Freshness loss. Thus, fatigue or feeling tired to make marriage into a How is it being there?
in my opinion, a good wife to marry a man is the greatest blessing in life.
very vague reference to the hearts of every man, how to define the
one, recalling the original really did not know the thing to marry a wife.
has been, since that is not too stupid, but I could not understand why a bride then. frank fall in love a lot of women really like children have so-called love and be loved, it seems like all of us worked hard with the excitement before, too depressed, to cry over. Unfortunately, the same can not seem destined to have a perfect ending love. Obviously, marriage and love is different is times they engaged in the process of confusing the object with a daughter to marry, but marriage is not clear as Well? for parents to complete the task? or drift, How ever.
good life should be said to be grinding out a good couple. which is not born a woman would be Dun Dun meters with meters, they really would not have to eat with it? How can men do not enjoy being miserable! suggested some women complain about men In the . a good day is not is critical.
four, every man selfish.
eating a bowl of pot think it is common problem for men, women relative to married this post is somewhat self-restraint. Turning off the rails, no matter what factors are responsible for marriage. every man is selfish, think of ways out about having a quiet and would not allow soup at home, his wife, in fact, quite a lot of women self-discipline.
short, to marry man a good wife is a blessing for a lifetime.

Kind of moment I finally understand love and miss
Click here for more pictures
a lovelorn girl, her very deeply hurt, I feel the whole world abandoned her, and even thought of death. She vowed never to fall in love in this life. She took the news told a boy, so the boy began to comfort her, encourage her, funny text messages every day prepared to make her happy. In this way, the girl gradually recovering from the pain, but also to become, and as lively past.
suddenly One day, the girl did not receive messages sent to him, felt a sense of loss and anxiety. she asked herself: not to think of him, but the boy's shadow looming in my mind is always floating around. she felt that strange thoughts, and love the feeling of the original not the same. When she was in love, the kind of thoughts like fire Like blazing, burning constantly, eating all their own, account for all their soul, in addition to thinking things can no longer do anything; and now, she can not tell, she never was there such a miss is faint, but nothing a little everywhere, but always need to pay anything to feel a warmth, like the corner of the room put a bouquet of lilies and a touch of fragrance filled the entire room, but not you deliberately think, make you feel uncomfortable.
girl determined to figure it out. One day, the boy called her to ask whether she had recently had fun. chatting chatting, she suddenly asked the boy why no women friend introduced him to do one. She asked when the heart beats very fast, but put on a joking tone. When the boy said, Well, do not know that to the courage, she suddenly said: think about me. ; she was not willing to ask: like, say: love and miss: This yearning is peaceful, is warm, it is not mixed with any thoughts, without any exclusive taste, without any idea of possession. girl suddenly remembered the boy once said, this world is only three colors: red , blue and green. Red is the impulse, passion, is to destroy all their forces; blue is depression, is profound, is the sink all their forces; green is peaceful, is a comfort, is to soothe all the power; after red love blue romance, then missing the green is your best Chicken Soup.
love the time is? weeks, months, or years? But no matter how long overdue love always . And this miss it, will never expire. beyond the feelings of love and friendship, is this yearning. Find a spiritual haven, you can safely go to parking; find a spiritual guardian angel, will never disoriented; When you find one, you're the happiest person in the world hh

New Development of International Trade Theory
International Economics, international trade theory is an important part of the open under the conditions of micro-economics, international trade theory in the main goods and services exchanged between countries to study the reasons for international commodity exchange, results, and related policy . scope of the study of international trade theory also includes the international flow of factors of production and international transfer of technical knowledge. the one hand, factors of production and technical knowledge as a particular commodity has its own international market, on the other hand, as factor inputs for goods and services play an important role in the production. International trade theory also studied the economic growth, technological change and trade interaction, from the dynamic analysis of international trade on the causes and consequences of change.
see from the history of economics, international trade theory can be traced back fifteenth century and early sixteenth century mercantilist doctrine. Smith and Ricardo's trade theory, labor is the only factor of production, production technology is a given exogenous variable, constant returns to scale production. Smith and Ricardo trade theory is part of the system of classical economic theory, known as the resource endowments Start with a new method to study the causes and consequences of trade, the study of new trade structure and trade policy, the creation of a series of new doctrine. After ten years of development, these theories have gradually matured. which has been incorporated as part of the textbook, Another part of the continuing discussion, is still the forefront of trade issues, and this paper will briefly describe these new developments in trade theory and explains its significance to China trade policy.
one, economies of scale, imperfect competition, industrial between developed countries and the same industry, trade
propose a new interpretation of the reasons for the trade is mainly developed from the late seventies the . Paul Krugman (Paul Krugman). this theory to the economies of scale in production and world markets based on imperfect competition explain the rapid industrial growth after the war between the country and the same industry, trade between.
economies of scale, trade theory [(1) a] development is based on two theories with different assumptions on the past: (1) production with economies of scale; (2) competition in the international market is incomplete.
specific stresses in the increase. In the participation in international trade before the enterprise is only for domestic demand. Since the limited domestic market demand, companies can not produce too much, so that the production costs and product prices have remained at a high level.
If the enterprises to participate in international trade, product market will be facing the expansion of domestic demand and foreign demand, companies can increase production. As the economies of scale in production stage, the production increase but reduced the average cost of the product, which in the international market increased the competitiveness.
the diversity of the industrial products, either State can not cover all the products of a sector, so that the international division of labor and trade is inevitable. But the specific focus on countries which produce a product which is there is no fixed pattern, both natural (competition) which can also be protocol division of labor. But the developed countries, industrial products between the comparative advantage.
Second, international trade, technology spillover, and economic growth
the late eighties early nineties, the international trade theory research is to focus on international trade and technological progress, the relationship between economic growth to be . in the economics literature, although there are many theoretical explanations of technology in trade and economic growth in the role, but a series of studies put the latest technology as an endogenous variable, not only to discuss the impact of technology on trade, but also of international trade, economic growth in the role of technological progress. to technological changes, imperfect competition, economies of scale and economic growth combined study is the latest development of international trade theory and cutting-edge topics.
the International Trade Theory The backdrop of new development in the post-war pattern of international trade change. in the use of economies of scale and imperfect competition theory that the current . Why are there economies of scale? industry economies of scale and how the formation of the international division of labor? If that technology development is an important difference and one of the reasons, then, how is the technology, development, delivery? technology development and international trade, economic growth relationship is? caused these issues of great interest to international economists. Scholars of international trade theory and growth theory combining the ideas put forward many new.
In recent years, study international economics, international trade, technical change and economic growth in many articles. its theoretical origin, it can be divided into two parts along the Ricardian model, still the technology as an exogenous variable , but from the dynamic point of view of technological change on trade patterns and the impact of national welfare, the other put the technology as an endogenous variable, not only how the impact of technology trade and growth, while the technology development as research, investment, trade and a result of economic growth, changes in research technology, international trade and economic growth in the relationship between each other.
1. technology as an exogenous variable in the trade and growth theory
(1) technical differences in the formation of trade patterns < br> In addition to (Makusen and Svenson, 1985) assumed in their study the proportion of resource allocation between the two countries are the same preferences and needs. production required more than two factor inputs, but do not have economies of scale. But if the two countries in the production Technically there are some subtle differences, labor productivity will be slightly different. in the two countries trade, countries will export their products relatively high factor productivity.
Davis (Davis) in his 1994 study Suppose two countries are also the two industries. The first of an industry produces a single product, and the second industry produces two products can not be completely replaced. Suppose one of them in the second production of the industry with foreign strategic there are technical differences in the production of a product which is technically slightly better than others. In conditions of free trade, factor prices equal to production and export of the country will make the product, while other countries will be the production of export another product.
Markusen, Svensson and Davis study shows that even in the constant returns to scale and perfectly competitive market, the technical differences between the products can also lead to the same industry (intramindustry) trade.
(2) technological change on trade patterns and welfare of
Krugman of the technological progress in 1986 on the welfare of developed and developing countries. In his model, he assumes there are two categories of countries: more technologically advanced countries (developed countries) and the technology is relatively backward countries (developing countries), the products are divided into two categories: technology-intensive products with non-technology-intensive products. These assumptions and Heck Break Seoul m Ohlin model somewhat similar, and its development is: If the technical change of (regardless of why the change), will benefit national trade patterns and what impact?
If such technological advances in developed countries, the result is no harm. First, the developed countries in terms of its technical higher, more advanced products, and as already leading in technology, newer technologies have not faced any competition, no threat to other countries , could not it also threatens other countries, so it is good and technological progress. Second, backward countries did not hurt, because the technology gap, and to the less advanced countries more space to develop and catch up. so technological progress occurs In the advanced countries is beneficial to both of these two groups of countries. For the only disadvantage is that advanced countries do have some technical advantages of the products, technology advances and production and export capacity, has the potential to lower prices of these products, trade conditions may become unfavorable.
if technical progress occurs in less advanced countries? Krugman that the result is narrowing the gap between the two countries, advanced countries of the original is a competition against them. backward countries because of their ability to produce such products and reduce imports, resulting in two results: First, the decline in the prices of these products, the advanced countries of the negative, and second, if such a product requires intensive use of already scarce backward country resources, then the backward countries is also unfavorable.
2. technology as endogenous variables of trade and growth theory
the other hand the development of trade theory is to technology as an endogenous variable to analyze, study the technical changes reasons, but also of technological progress as a result of production and trade patterns of trade and social welfare. technological change, there are two sources, one is passive, not out by the study of development, but from the case, Dry learned is learned through economic behavior, called created. This technical change is an innovation (innovation). technological innovation is the research and development in general (Research and Development, referred to as the R & D) results.
(1) ) and learning process sometimes is not the original purpose, but in other economic activities engaged in production or a natural byproduct of the time. As the owner of advanced technology, and sometimes it is not intended for sale or distribution of their technology, but in the trade or other economic activity the natural output of the technology, known as the technology The. technological spillovers, but also can be divided into international and domestic, inter-industry and industry in several different situations.
a) international spillover
international spillover refers to the technology through direct or indirect (eg through trade) transmitted to other countries, so that producers in other countries have gradually mastered these techniques.
To illustrate the technology in the international spillovers, we assume there are two countries: A countries and B countries, countries in the production of two products, X and Y. In both countries there is no trade, the country produced by the country's production technology and resource allocation decisions, A comparative advantage of state-owned production of X, B Y, the country will have comparative advantage in production. If the two trade occurred, according to can not be a monopoly, commodity trade through technology spillovers have a variety of different results. a situation, A would have been the country's comparative advantage in production of goods X, but B countries more advanced production technology X, there is an absolute advantage. A State B State introduced the production of goods X technology to improve the productivity of do have a comparative advantage. This result played a comparative advantage on its own resources, is conducive to long-term growth A country. In addition, commodity X is B countries have been relatively short term, the division of labor between the two countries after no longer in production and trade. A country can produce more X B countries, the import prices, but also conducive to B countries. this technology spillover to the original from absolute advantage do not have a comparative advantage of A Y. countries, this technology is a result of the introduction of import substitution-oriented growth, but B is a threat for the country and the competition. If A country Y requires intensive use of production its scarce resources, the country's long-term development of A is not necessarily beneficial. trade and technological spillovers are likely to develop into the br> b) domestic technology spillover
domestic technology spillover refers to the technology spread within the country. Because of geography, language, culture and other reasons, the domestic spillover faster than the learning of foreign technology.
eighties later, Krugman, and Lucas (Lucas), respectively, discussed the problem of domestic technology spillover. In Krugman (1987) model, he assumed the two countries A and B, produces a range of products. which Congress in any number of production technology in the initial lead. Despite the international spread of technology, but the domestic technology spillover will be faster. With the passage of time and a faster process of domestic technology spillovers, the The original will accelerate the development of leading industry possible, the original comparative advantage will increase, differences between countries to expand.
Lucas (1988) model and is somewhat similar to Krugman, but he assumed a number of countries, producing two products: X and Y. countries in the same labor and labor productivity, but technical knowledge of the two products different levels of the original master. Some countries produce X, and some countries produce Y, the formation of the first international division of labor. As technology spillover in the country, producing countries X and Y will produce a professional production in their respective continuous improvement in labor productivity, so that the countries the two products on the mastery of technical knowledge gap is growing. In general, countries in the international division of labor is hard to change, unless the product with the growth rate of labor productivity is not on the rate of price decline to change the original status of the international division of labor, a product from production to production of another product, can only be had in those countries on the edge (marginal country).
Crew Gehman and the Lucas analysis shows: the first of a country's comparative advantage, industry selection and position in the international division of labor may be with its own technical knowledge and resources, but also on factors that may be due to chance, but the initial industry structure once formed, the spillover of domestic production technology allows a country's productivity in these industries increased faster than other countries, will make the country's leading position in these industries is more consolidated. This explains why, in a sense Some countries specialize in certain industries, while others specialize in other industries, which is a spillover of domestic relations. Moreover, once formed a production patterns, change is not easy, because the scale of the industry and the domestic spillover will continue to improve labor productivity, as long as the cost of labor productivity growth rate is lower than the growth rate, it will be profitable and continue to exist. the history of a country in determining the long-term patterns of production and trade play an important role.
c) inter-industry and industry technology spillover
spillover can occur between different sectors (intermindustry) and within the same industry, although the different products in many industries, but many of the resources used are the same, How to improve factor productivity of the industries are all promoted. In addition, where the technological advantage may also be spillover to other sectors to other industries also increased productivity, and impact on long-term development of society. [(1) c]
the same industry may have different industry groups (industry clusters), the Group's production technology producing similar products, but not identical. and abroad compared to similar industry groups, the production will have different advantages. international trade and the resulting competition and technology spillovers will shorten the Industry Group the technology gap.
(2) Development (R & D) and technological innovation (Innovation)
Another source of technological change technological innovation, it is an investment, research and development results. New Technology development mainly in: a) improve factor productivity, with limited resources to produce more products, or to ensure that the case of production, use fewer resources; b) improvement of product quality and new product development.
technological innovation or development of technical progress in the degree of specialization can occur. With the production of the social division of labor more and more detailed, a final product can be turned into a business enterprise to produce as many. the same enterprise also can be divided into many sectors, each sector produces only one product components. high degree of specialization so that each department is focused only on a small scale mass production of parts in this specific production, enterprises are likely to profit by reducing costs. In other words, degree of specialization not only the profit obtained from the final product, every production processes are independent, have the possibility of profit. the pursuit of profit to production Technology has improved on every aspect of power.
developing technical progress are often in the development of new products obtained. Market competition has forced enterprises to continuously develop new products or improve product quality, thus creating new technologies.
and a country can be substantial progress in developing technologies, requires two necessary conditions: (1) protection of intellectual property, because there is no protection, develop new products and their benefits the risk asymmetry, but also no incentive to invest in research. (2) To encourage research and investment. Although learning by doing can improve the technology, but there are limits, after all, after all, had to cut the gap with the advanced technology, technical leader of a country in order to be have developed type of technological progress, but the development of technical progress is needed to guarantee the legal and investment.
international trade and development-oriented technical change are mutually reinforcing relationship, the impact of trade on technological innovation, not only through the international market competition is forcing countries to develop new technologies and new products, but also to countries through the international spillover opportunities for mutual inspiration. The new technologies not only the behavior of individual countries, and to become the joint efforts of all countries. Here there is a side economies of scale in technology development problem. In a sense, the international flow of trade and technology research and development can make the formation of , on this basis to further develop a process and not repeat the same. Of course, doing so requires a lot of political and technological conditions, but from the perspective of economics, this is a way of optimal allocation of resources.
another On the one hand, technological innovation can affect trade patterns. in technology as an exogenous variable and the Why are there gaps. technology as endogenous variables of the model have revealed the technology gap is the root cause. Throughout history, we can see that, although the technology and the international foreign overflow process of learning by doing is technically possible to shorten the gap between countries, national existing resources and technology to a country's long-term development and the status in the international division of labor still plays an important role. Therefore, to enhance investment in research and development to develop new technologies to improve the status of a country's trade long-term economic growth and ensure the necessary measures.
three new theory of international trade and further reform and opening up to China over the past fifteen years
revelation, although we have made great achievements in the opening, but still trade policy Many traditional ideas. We made many efforts in the export, but hesitates to open up the domestic market. resumption of GATT status in the application process, we expand imports and open markets into the GATT as a the price is right to have to bear some kind of the protection of certain industries is necessary, can be understood. The question is, how to choose protected objects? ways in which to protect? protect the future and at what price? We must fully estimate the costs of protection, and efforts to minimum cost to achieve our development objectives advanced or infant industries.
classical and neoclassical trade theory has analyzed the protection to consumers and the national welfare brought about by the loss. spillover and learning by doing on the theory and for us to reveal the loss of protection . computers and other knowledge products and general consumer goods, not the same, the use of computers and the popularization of science and technology contains the spread and labor productivity. computers can bring rapid spread of the external effects can not be measured in monetary Moreover, computer development of the industry is not about hardware but the software only on the basis of popularity in order to have sufficient human capital and market demand for software development. by way of trade barriers to protect infant industries, the cost and results must be considered .
trade theory of economies of scale for our trade policy has also put forward many new ideas, new trade theory reveals the contemporary international market competition and the monopoly of trade-oriented features of industrial products, industrial products, the diversity makes any A country can have sufficient resources to produce and export all of the industrial products. International trade has become more and more space, even within the same industry may also import and export of both. modern international competition is not limited to pros and cons of individual products, so we do not need to restrict the import of foreign high-quality products, do not have to produce the foreign accounts through protection advantage. opening up some markets does not mean that the domestic industry can not develop a similar . others produced a few types of models, we can focus our resources or new production of other types of models, and reduce costs through economies of scale to export.
how to make the economies of scale in some industries? economies of scale made in trade theory a factor. If the Government can properly select some promising and can give full play to their advantages in resources industries, through policy support, to help them reach a certain scale of production, then to their own interests and development will be beneficial. This focus on trade protection long-term strategic development of a country, known as the protection. It takes a period of industrial protection, and then transfer. protection purposes only hope that the period of protection, makes the industry itself produce a technological spillover and self-growing capacity in the short term to improve productivity and competitiveness. Protection of the time is short, the protection industry is changing. Paul Krugman borrowed Givens (Givens, 1982) to say, its called Band).
whether it is the policy of free trade is be considered. what the policy of what industry, should have analyzed the pros and cons as accurate as possible. is not a new theory of international trade tells us that the issue should not be protected, but to our trade policy provides more options to consider problems. simply use trade barriers to protect infant industries is a passive way and the old, the price is not small. but from a strategic point of view of the development of certain products (not necessarily the whole industry) may bring about the implementation of protection long-term advantages and benefits, but these products may not be infant industries, means of protection are not necessarily barriers to trade, can be less costly industrial policy or consumer policy, protection should be a short period of time, this protection is a kinds of positive and promising protection.

see from the history of economics, international trade theory can be traced back fifteenth century and early sixteenth century mercantilist doctrine. Smith and Ricardo's trade theory, labor is the only factor of production, production technology is a given exogenous variable, constant returns to scale production. Smith and Ricardo trade theory is part of the system of classical economic theory, known as the resource endowments Start with a new method to study the causes and consequences of trade, the study of new trade structure and trade policy, the creation of a series of new doctrine. After ten years of development, these theories have gradually matured. which has been incorporated as part of the textbook, Another part of the continuing discussion, is still the forefront of trade issues, and this paper will briefly describe these new developments in trade theory and explains its significance to China trade policy.
one, economies of scale, imperfect competition, industrial between developed countries and the same industry, trade
propose a new interpretation of the reasons for the trade is mainly developed from the late seventies the . Paul Krugman (Paul Krugman). this theory to the economies of scale in production and world markets based on imperfect competition explain the rapid industrial growth after the war between the country and the same industry, trade between.
economies of scale, trade theory [(1) a] development is based on two theories with different assumptions on the past: (1) production with economies of scale; (2) competition in the international market is incomplete.
specific stresses in the increase. In the participation in international trade before the enterprise is only for domestic demand. Since the limited domestic market demand, companies can not produce too much, so that the production costs and product prices have remained at a high level.
If the enterprises to participate in international trade, product market will be facing the expansion of domestic demand and foreign demand, companies can increase production. As the economies of scale in production stage, the production increase but reduced the average cost of the product, which in the international market increased the competitiveness.
the diversity of the industrial products, either State can not cover all the products of a sector, so that the international division of labor and trade is inevitable. But the specific focus on countries which produce a product which is there is no fixed pattern, both natural (competition) which can also be protocol division of labor. But the developed countries, industrial products between the comparative advantage.
Second, international trade, technology spillover, and economic growth
the late eighties early nineties, the international trade theory research is to focus on international trade and technological progress, the relationship between economic growth to be . in the economics literature, although there are many theoretical explanations of technology in trade and economic growth in the role, but a series of studies put the latest technology as an endogenous variable, not only to discuss the impact of technology on trade, but also of international trade, economic growth in the role of technological progress. to technological changes, imperfect competition, economies of scale and economic growth combined study is the latest development of international trade theory and cutting-edge topics.
the International Trade Theory The backdrop of new development in the post-war pattern of international trade change. in the use of economies of scale and imperfect competition theory that the current . Why are there economies of scale? industry economies of scale and how the formation of the international division of labor? If that technology development is an important difference and one of the reasons, then, how is the technology, development, delivery? technology development and international trade, economic growth relationship is? caused these issues of great interest to international economists. Scholars of international trade theory and growth theory combining the ideas put forward many new.
In recent years, study international economics, international trade, technical change and economic growth in many articles. its theoretical origin, it can be divided into two parts along the Ricardian model, still the technology as an exogenous variable , but from the dynamic point of view of technological change on trade patterns and the impact of national welfare, the other put the technology as an endogenous variable, not only how the impact of technology trade and growth, while the technology development as research, investment, trade and a result of economic growth, changes in research technology, international trade and economic growth in the relationship between each other.
1. technology as an exogenous variable in the trade and growth theory
(1) technical differences in the formation of trade patterns < br> In addition to (Makusen and Svenson, 1985) assumed in their study the proportion of resource allocation between the two countries are the same preferences and needs. production required more than two factor inputs, but do not have economies of scale. But if the two countries in the production Technically there are some subtle differences, labor productivity will be slightly different. in the two countries trade, countries will export their products relatively high factor productivity.
Davis (Davis) in his 1994 study Suppose two countries are also the two industries. The first of an industry produces a single product, and the second industry produces two products can not be completely replaced. Suppose one of them in the second production of the industry with foreign strategic there are technical differences in the production of a product which is technically slightly better than others. In conditions of free trade, factor prices equal to production and export of the country will make the product, while other countries will be the production of export another product.
Markusen, Svensson and Davis study shows that even in the constant returns to scale and perfectly competitive market, the technical differences between the products can also lead to the same industry (intramindustry) trade.
(2) technological change on trade patterns and welfare of
Krugman of the technological progress in 1986 on the welfare of developed and developing countries. In his model, he assumes there are two categories of countries: more technologically advanced countries (developed countries) and the technology is relatively backward countries (developing countries), the products are divided into two categories: technology-intensive products with non-technology-intensive products. These assumptions and Heck Break Seoul m Ohlin model somewhat similar, and its development is: If the technical change of (regardless of why the change), will benefit national trade patterns and what impact?
If such technological advances in developed countries, the result is no harm. First, the developed countries in terms of its technical higher, more advanced products, and as already leading in technology, newer technologies have not faced any competition, no threat to other countries , could not it also threatens other countries, so it is good and technological progress. Second, backward countries did not hurt, because the technology gap, and to the less advanced countries more space to develop and catch up. so technological progress occurs In the advanced countries is beneficial to both of these two groups of countries. For the only disadvantage is that advanced countries do have some technical advantages of the products, technology advances and production and export capacity, has the potential to lower prices of these products, trade conditions may become unfavorable.
if technical progress occurs in less advanced countries? Krugman that the result is narrowing the gap between the two countries, advanced countries of the original is a competition against them. backward countries because of their ability to produce such products and reduce imports, resulting in two results: First, the decline in the prices of these products, the advanced countries of the negative, and second, if such a product requires intensive use of already scarce backward country resources, then the backward countries is also unfavorable.
2. technology as endogenous variables of trade and growth theory
the other hand the development of trade theory is to technology as an endogenous variable to analyze, study the technical changes reasons, but also of technological progress as a result of production and trade patterns of trade and social welfare. technological change, there are two sources, one is passive, not out by the study of development, but from the case, Dry learned is learned through economic behavior, called created. This technical change is an innovation (innovation). technological innovation is the research and development in general (Research and Development, referred to as the R & D) results.
(1) ) and learning process sometimes is not the original purpose, but in other economic activities engaged in production or a natural byproduct of the time. As the owner of advanced technology, and sometimes it is not intended for sale or distribution of their technology, but in the trade or other economic activity the natural output of the technology, known as the technology The. technological spillovers, but also can be divided into international and domestic, inter-industry and industry in several different situations.
a) international spillover
international spillover refers to the technology through direct or indirect (eg through trade) transmitted to other countries, so that producers in other countries have gradually mastered these techniques.
To illustrate the technology in the international spillovers, we assume there are two countries: A countries and B countries, countries in the production of two products, X and Y. In both countries there is no trade, the country produced by the country's production technology and resource allocation decisions, A comparative advantage of state-owned production of X, B Y, the country will have comparative advantage in production. If the two trade occurred, according to can not be a monopoly, commodity trade through technology spillovers have a variety of different results. a situation, A would have been the country's comparative advantage in production of goods X, but B countries more advanced production technology X, there is an absolute advantage. A State B State introduced the production of goods X technology to improve the productivity of do have a comparative advantage. This result played a comparative advantage on its own resources, is conducive to long-term growth A country. In addition, commodity X is B countries have been relatively short term, the division of labor between the two countries after no longer in production and trade. A country can produce more X B countries, the import prices, but also conducive to B countries. this technology spillover to the original from absolute advantage do not have a comparative advantage of A Y. countries, this technology is a result of the introduction of import substitution-oriented growth, but B is a threat for the country and the competition. If A country Y requires intensive use of production its scarce resources, the country's long-term development of A is not necessarily beneficial. trade and technological spillovers are likely to develop into the br> b) domestic technology spillover
domestic technology spillover refers to the technology spread within the country. Because of geography, language, culture and other reasons, the domestic spillover faster than the learning of foreign technology.
eighties later, Krugman, and Lucas (Lucas), respectively, discussed the problem of domestic technology spillover. In Krugman (1987) model, he assumed the two countries A and B, produces a range of products. which Congress in any number of production technology in the initial lead. Despite the international spread of technology, but the domestic technology spillover will be faster. With the passage of time and a faster process of domestic technology spillovers, the The original will accelerate the development of leading industry possible, the original comparative advantage will increase, differences between countries to expand.
Lucas (1988) model and is somewhat similar to Krugman, but he assumed a number of countries, producing two products: X and Y. countries in the same labor and labor productivity, but technical knowledge of the two products different levels of the original master. Some countries produce X, and some countries produce Y, the formation of the first international division of labor. As technology spillover in the country, producing countries X and Y will produce a professional production in their respective continuous improvement in labor productivity, so that the countries the two products on the mastery of technical knowledge gap is growing. In general, countries in the international division of labor is hard to change, unless the product with the growth rate of labor productivity is not on the rate of price decline to change the original status of the international division of labor, a product from production to production of another product, can only be had in those countries on the edge (marginal country).
Crew Gehman and the Lucas analysis shows: the first of a country's comparative advantage, industry selection and position in the international division of labor may be with its own technical knowledge and resources, but also on factors that may be due to chance, but the initial industry structure once formed, the spillover of domestic production technology allows a country's productivity in these industries increased faster than other countries, will make the country's leading position in these industries is more consolidated. This explains why, in a sense Some countries specialize in certain industries, while others specialize in other industries, which is a spillover of domestic relations. Moreover, once formed a production patterns, change is not easy, because the scale of the industry and the domestic spillover will continue to improve labor productivity, as long as the cost of labor productivity growth rate is lower than the growth rate, it will be profitable and continue to exist. the history of a country in determining the long-term patterns of production and trade play an important role.
c) inter-industry and industry technology spillover
spillover can occur between different sectors (intermindustry) and within the same industry, although the different products in many industries, but many of the resources used are the same, How to improve factor productivity of the industries are all promoted. In addition, where the technological advantage may also be spillover to other sectors to other industries also increased productivity, and impact on long-term development of society. [(1) c]
the same industry may have different industry groups (industry clusters), the Group's production technology producing similar products, but not identical. and abroad compared to similar industry groups, the production will have different advantages. international trade and the resulting competition and technology spillovers will shorten the Industry Group the technology gap.
(2) Development (R & D) and technological innovation (Innovation)
Another source of technological change technological innovation, it is an investment, research and development results. New Technology development mainly in: a) improve factor productivity, with limited resources to produce more products, or to ensure that the case of production, use fewer resources; b) improvement of product quality and new product development.
technological innovation or development of technical progress in the degree of specialization can occur. With the production of the social division of labor more and more detailed, a final product can be turned into a business enterprise to produce as many. the same enterprise also can be divided into many sectors, each sector produces only one product components. high degree of specialization so that each department is focused only on a small scale mass production of parts in this specific production, enterprises are likely to profit by reducing costs. In other words, degree of specialization not only the profit obtained from the final product, every production processes are independent, have the possibility of profit. the pursuit of profit to production Technology has improved on every aspect of power.
developing technical progress are often in the development of new products obtained. Market competition has forced enterprises to continuously develop new products or improve product quality, thus creating new technologies.
and a country can be substantial progress in developing technologies, requires two necessary conditions: (1) protection of intellectual property, because there is no protection, develop new products and their benefits the risk asymmetry, but also no incentive to invest in research. (2) To encourage research and investment. Although learning by doing can improve the technology, but there are limits, after all, after all, had to cut the gap with the advanced technology, technical leader of a country in order to be have developed type of technological progress, but the development of technical progress is needed to guarantee the legal and investment.
international trade and development-oriented technical change are mutually reinforcing relationship, the impact of trade on technological innovation, not only through the international market competition is forcing countries to develop new technologies and new products, but also to countries through the international spillover opportunities for mutual inspiration. The new technologies not only the behavior of individual countries, and to become the joint efforts of all countries. Here there is a side economies of scale in technology development problem. In a sense, the international flow of trade and technology research and development can make the formation of , on this basis to further develop a process and not repeat the same. Of course, doing so requires a lot of political and technological conditions, but from the perspective of economics, this is a way of optimal allocation of resources.
another On the one hand, technological innovation can affect trade patterns. in technology as an exogenous variable and the Why are there gaps. technology as endogenous variables of the model have revealed the technology gap is the root cause. Throughout history, we can see that, although the technology and the international foreign overflow process of learning by doing is technically possible to shorten the gap between countries, national existing resources and technology to a country's long-term development and the status in the international division of labor still plays an important role. Therefore, to enhance investment in research and development to develop new technologies to improve the status of a country's trade long-term economic growth and ensure the necessary measures.
three new theory of international trade and further reform and opening up to China over the past fifteen years
revelation, although we have made great achievements in the opening, but still trade policy Many traditional ideas. We made many efforts in the export, but hesitates to open up the domestic market. resumption of GATT status in the application process, we expand imports and open markets into the GATT as a the price is right to have to bear some kind of the protection of certain industries is necessary, can be understood. The question is, how to choose protected objects? ways in which to protect? protect the future and at what price? We must fully estimate the costs of protection, and efforts to minimum cost to achieve our development objectives advanced or infant industries.
classical and neoclassical trade theory has analyzed the protection to consumers and the national welfare brought about by the loss. spillover and learning by doing on the theory and for us to reveal the loss of protection . computers and other knowledge products and general consumer goods, not the same, the use of computers and the popularization of science and technology contains the spread and labor productivity. computers can bring rapid spread of the external effects can not be measured in monetary Moreover, computer development of the industry is not about hardware but the software only on the basis of popularity in order to have sufficient human capital and market demand for software development. by way of trade barriers to protect infant industries, the cost and results must be considered .
trade theory of economies of scale for our trade policy has also put forward many new ideas, new trade theory reveals the contemporary international market competition and the monopoly of trade-oriented features of industrial products, industrial products, the diversity makes any A country can have sufficient resources to produce and export all of the industrial products. International trade has become more and more space, even within the same industry may also import and export of both. modern international competition is not limited to pros and cons of individual products, so we do not need to restrict the import of foreign high-quality products, do not have to produce the foreign accounts through protection advantage. opening up some markets does not mean that the domestic industry can not develop a similar . others produced a few types of models, we can focus our resources or new production of other types of models, and reduce costs through economies of scale to export.
how to make the economies of scale in some industries? economies of scale made in trade theory a factor. If the Government can properly select some promising and can give full play to their advantages in resources industries, through policy support, to help them reach a certain scale of production, then to their own interests and development will be beneficial. This focus on trade protection long-term strategic development of a country, known as the protection. It takes a period of industrial protection, and then transfer. protection purposes only hope that the period of protection, makes the industry itself produce a technological spillover and self-growing capacity in the short term to improve productivity and competitiveness. Protection of the time is short, the protection industry is changing. Paul Krugman borrowed Givens (Givens, 1982) to say, its called Band).
whether it is the policy of free trade is be considered. what the policy of what industry, should have analyzed the pros and cons as accurate as possible. is not a new theory of international trade tells us that the issue should not be protected, but to our trade policy provides more options to consider problems. simply use trade barriers to protect infant industries is a passive way and the old, the price is not small. but from a strategic point of view of the development of certain products (not necessarily the whole industry) may bring about the implementation of protection long-term advantages and benefits, but these products may not be infant industries, means of protection are not necessarily barriers to trade, can be less costly industrial policy or consumer policy, protection should be a short period of time, this protection is a kinds of positive and promising protection.

On the physical classroom smile 』『 three Daming County, Hebei Province Hongmiao
Dan Guangling
a successful high school physical education, whether it is the usual classroom teaching or teaching and research courses, race courses, should be Three Smiles essential, but the focus here to discuss the use of teaching methods are not correct or not, but how to play to the characteristics of existing materials to make teaching more with fun, active classroom atmosphere. In general, we like to choose their own familiar or the implementation of the contents of good teaching, it will be more handy. But Select the rhythm of male teachers may be teaching activities, or the content of female teachers face football and so on. At this time we are required to find and use features to create classroom materials on the br> students are teaching the subjects, must give full play to their main role, from passive acceptance to active learning. To make the students in the classroom, praise, less criticism, teachers too serious, will inevitably produce a sense of distance and the students a sense of fear, if the first reaction of the students finish the exercise is to observe teachers face during practice and not feel the satisfaction, then the student will always are let them think demonstration, explanation is the most accurate infected students. but beyond that, teachers should also not be pro-mei, get along with, willing to work with teachers, with the completion of teaching tasks.
teachers and students more intimate. on the part of the game in this class, when the first pass after the game finished, winning cheers from a group of not very warm, when the end of the game with the second time, I side direction to the team, while made to them to be cheering the I deliberately shook his head and said:
in the classroom teaching, adequate preparation is the foundation, in the classroom to do the unique new idea, any one class would be the best.
physics experiment teaching and training of student ability

soul of a nation experimental science, the discovery of physical laws and the establishment of physical theory must be based strictly based on physical experiments, and are subject to experimental test. Therefore, in physics teaching, especially in the experimental teaching, pay attention to constantly motivate the students through observation, comparison, experiment, induction, analogy and other means of exploring the various assumptions and conjecture proposed the development of their sense of innovation is particularly important to obvious. in high school physics experiment teaching how to cultivate creativity in our students do?
one demonstration experiment is an exploratory variable experiment, students of innovation
in the past, the general classroom demonstration experiment as the main teacher, the students merely spectators, not directly involved, detrimental to their innovative ability. to explore the demonstration experiment to experiment, so that students to the brain, hands, tongue, students play the main role, which will help stimulate the creative thinking of students.
Second, using a variety of experimental methods, active students thinking.
experimental groups for students, we to help students master the test based on the principle that allows students to use different equipment, different experimental procedure for experiments. In the experiment, students need to be trade-offs in a variety of factors, from information on the screen. This requires the students to set goals around the corner process, there is a global perspective and good compromise adaptable in different situations, the resilience of students, students of abstraction have been integrated skills training and development.
Third, the creation of test questions to promote student innovation
innovative teaching capacity development is the study of the elements, leading, find sex, inductive and other organic combination, which requires creative teachers in the experimental application of modern teaching methods and teaching methods, will be a variety of teaching methods to optimize the combination of can also be developed to create activities to encourage students to create.
Fourth, maintaining a positive attitude, active exploration and research
positive that, you one step ahead, one step ahead, you're ahead of an era. Learning is not easy, need to a strong determination and positive attitude, otherwise, only halfway, nothing. the learning process in physics experiments to note the following points: 1, analysis of student grouping experiments .2 anomalies occurred, observe the teacher The demonstration experiment .3, .4 to do extra small experiments, careful analysis of physical phenomena in everyday life.
by physical experiments, not only to achieve the material presented for each experiment experimental purposes, for routine experimental verification of education; but also scientific experiments literacy students, combining theory with practical and realistic scientific style, meticulous serious scientific attitude; more importantly, by grouping experiments, classroom demonstration, a small experiment and extra-curricular physical phenomena in everyday life close observation and diligent in thinking, students take the initiative to study the spirit of exploration and creative discovery, and solve new practical problems.
reflect the chemical experiment of teaching the art of Yongnian County, Hebei Province, the second

one enlightening
the unity of opposites is the teaching and learning the nature of relationships. With the deepening of the implementation of quality education, people's educational concept is gradually changing, from teaching to self-transition, and fully reflects the leading role of teachers and students in the dominant position. in Teaching Teachers inspire and induction of students into teaching art as well. Chemistry is a lab-based disciplines, to enrich their experience and knowledge, can not do without chemical experiment; to create new products is also inseparable from the chemical experiment. chemistry experiment is to train students in creative thinking the best way.
demonstration experiment for the teaching and student of existing experimental content, methods and steps for improvement; also need to be supplemented with teaching some of the key experimental demonstration experiment or students. clever idea, well-designed discoverers and explorers of the students placed in the position. With the problem of layers of depth, not only to enable students to consolidate their knowledge, but also feelings of success and happiness in the innovation, the activation of the innovative thinking, improve innovation capabilities. With deepening of the reform of education and teaching, research study is the information age, the embodiment of the school educational requirements, is a teacher's own innovation performance, innovation capability is one of students we try and practice, and research study can not do without experiment.
Third, the lack of aesthetic beauty of
education is incomplete education, education is not complete full development is difficult to train qualified personnel. aesthetic is reflected in all aspects of education including the teaching of chemistry experiments . students to experiment not only training the basic skills, but also shape the United States, reflecting the source of the United States. Experiments show that under the correct guidance of teachers, students observe the experiment experimental discipline, flexible operation, bold but cautious, fully embodies the psychological quality of the United States, experimental operation the United States.
four scientific
chemistry is a natural science, natural science, of course inseparable from the experiments, development of education in high school chemistry experiment more prominent importance. Experiment shows the process of education itself is not only scientific and reflects the teacher's education in the experiment to develop attitudes and develop students in the experimental scientific method of learning. experiment is a scientific question, for thinking is not just a scientific issue based on past experience and knowledge of all , but according to the environmental issues and basic principles, bold vision, careful argument.
chemistry experiment is the continuous development of improved survival and the basis for the emotional and students in the experiment, operation of the skill, the students interest of all to show the art high school chemistry experiment. how to better play to the art of high school chemistry experiment, each chemical educators deserve our research and exploration.

the teaching of biology students thinking
comparison Cixian Hebei government-run school district to spend the new
Hu compare the activities of thinking is creative thinking and effective a way of thinking common components. It refers to two or more under the same or similar characteristics comparison between things, from one thing to speculate on some known characteristics of the corresponding features of other things, the existence of differences in seeking common ground, with the divergent, resulting in new knowledge, draw conclusions and creative. Comparative Biology students have the obvious advantage of thinking, teachers should give full play to the advantages of comparative thinking ability of students.
First, comparative thinking in teaching status and role of
1. for the concept of teaching is conducive to deepening the understanding of the concept of students in the teaching process, using comparative way of thinking of students to different real discrimination looks like the problems linked to enable students to accurately grasp the essence of the concept, impressive, not easy to forget, but also allows students to also remember a few similar concepts. long-term effect, it will improve their thinking ability.
2 to impart new knowledge, help students to consolidate old knowledge, deepen their understanding of new knowledge and memory of new knowledge in teaching, teachers should make full use of existing knowledge, application of comparative thinking, linking the old and new knowledge, differences in seeking the same, with the divergent guide students to draw knowledge .
3, for review of teaching is beneficial to the students the knowledge or the total systematic review by periodic review, the biological knowledge of the system to link up to form the overall concept. in the review stage, the method used to compare similar Even the concept of the opposite order for the systematic knowledge of materials is conducive to store memories in the brain, is conducive to positive transfer of knowledge, is conducive to the comprehensive thinking ability students.
two main methods of thinking Cultivation of comparative thinking
not only for teachers, student learning is an important and effective method. In teaching, teachers should carefully study materials, depending on the content, select the comparison of different methods used to organize the teaching.
1 tabular comparison law is a teacher in explaining biological concepts, principles, through the prompt internal relations of things, summarized the similarities, differences or common law, and expressed in the form of tables, to facilitate students to compare induction and flexible memory.
2 biological analysis and comparison method mix, knowledge complexity, by their nature, characteristics, comparative analysis of internal links, to make the knowledge and systematic. In teaching, can be used before and after contact, compared to explain, explain the system so that students grasp the characteristics of knowledge based on the complete control of biological knowledge.
3 biology test comparison method is an experimental science. the so-called comparative experiment is based on the experimental purpose, the subjects were divided into two (or more), One is the control, as a comparison standard, one (or more) is an experimental subject, its treatment measures taken, and then observe and compare the experimental results or changes in the experimental data to test conclusions drawn.
4 Photo Comparative Law this method. It helps to highlight the structure and function, form a unified structure and living environment and enhance the knowledge of the inner links and highlights the evolutionary point of view, so that students easily identify, understand, remember and master. both vertical comparisons but also horizontal comparison, through the systematic analysis and comparison of different categories and summarized the similarities and biological characteristics, the biology of learning from hard shift, simplify.
optimize the development of mathematics teaching thinking skills of students
Hebei County Canton Province Canton City School Shi Lanyu Pingjhen
Central School is both a controlled process of teaching the process of information flow, the task is completed the main way of teaching mathematics. on the formation of the teaching process optimization of various structural control and regulation system , it is a large area to improve the quality of primary school mathematics teaching the key. Therefore, as in the leading role in the process of teaching teachers, with particular emphasis on optimizing the development of mathematics teaching one student's thinking ability
, motivational, the quality of students thought the intention
direct promotion of human motivation is internal motivation of the activities and power, the psychologist Bruner to personality, his activities are dominated by interest in all the activities to be effective for a certain interest in a prerequisite. interested can generate motivation, student learning is one of the important sources of power, with interest, teaching to achieve good effect.
Second, increasing entropy with information to enhance the density
to stimulate thinking, thinking, activities must be effective control of the process of teaching a planned and purposeful transfer of information with entropy, to improve the density of thinking.
1. to the internal language students to think independently. mathematics teaching, students can give full play to make learning initiative, which requires teachers to students as thinking requires, but also to leave some space for students to think independently. In teaching students to think about and then do it. to enable students to speech and action control to gradually play a conscious role in promoting the thinking of the inner speech to promote logical thinking capabilities of students. modern education concept that mathematics teaching is the teaching of mathematics activities, namely, the teaching of thinking activity. Language is usually thought of thinking is the language of shell hh shown as the carrier. the student's cognitive law school students with the operation, the hands should, think for the expression of dynamic combination of mouth, that is, from the logical thinking. the main thinking things are good at different levels in the vertical and horizontal two aspects of development, to the depth and breadth of development issues to achieve a comprehensive understanding of things. To this end, teachers should pay attention to the process of teaching in mathematics to reveal mathematical essence of the problem, to help students improve their thinking ability concise. In problem-solving process, the first overall analysis of the issues, build mathematical models of thinking, and then outside to the inside, revealing the essence of problems. when the problem tends to resolve after from here, a systematic study related issues, so that you can solve a problem for solving a class of problems, that analogy. to question the application of training, for example, teachers should be good from the horizontal, vertical, reverse, multi-level system , the evolution of multi-up, expand, deepen, in order to improve mathematics teaching in the density and capacity. are the only way to achieve not increase the burden on students, but also the purpose of improving teaching quality.
optimize the mathematics classroom teaching, development thinking ability of students, teaching objectives must be clear, focused teaching, teaching methods and reasonable in order to ensure teaching effectiveness and reduce the heavy burden of students to implement.
how to improve the plug-speak, write, then teaching
Hebei Qiuxian Center School Liuzeng Jun
Nanxincun shop now language teaching, learning and more emphasis in the text for students to explore the main angle, in fact, pay more attention to the process of writing and pay attention to the main body of students a sense, become the passive subject traction to the idea of active extension. From the Process of writing instruction, to establish the status of students, students living in close contact, attention to the role of emotional power, it is an important guiding principle. in the composition process of teaching teachers to stimulate student life, learning memory the basis of emotion into the teachers to enable students to create scenarios, scenarios linked together, encouraging students to express the idea of an orderly end to form the text for the results.
one. music into the title, sparking memories of the
Picture Talk, write, then the fourth volume is used in teaching moral education course wall charts students in the first volume Kantuxuewen the introduction of teaching background. from the effects of view, students interested in this interesting situation to be aroused. and memories Ye Hao, Ye Hao gave the students a set of scenarios is the emotional experience of beauty is a harmony, peace atmosphere, and viewer of teaching the subject is different, which in turn will enable students to gradually realize the contrast of emotional meaning map.
II. inspire enthusiasm, and guide students in learning activities
the owner, just follow education law, to create a relaxed, harmonious, democratic atmosphere of teaching, students can fully active, lively, vivid development. When the wall charts show, the students have a surprised expression, because the four theme emerged in a chart stray geese encountered fierce attack eagle, and finally with the help of geese out of danger. This is formed into the atmosphere different. Although Figure meaning is obvious, but let the children speak out is not easy. I designed Some links and take advantage of causal factors to stimulate students to think and express enthusiasm, let them say to each other, said that in public.
III. full praise, attention to composition class of all those heads at
flexible, open-minded The students are the most active, because they first read map views, clear thinking, a more accurate expression of confidence is also very full. In contrast to those thinking more slowly, not very well express less confidence in the students, always fear of students and teachers because of the error is ridiculed. so full attention to writing in the teaching experience of all students, in a timely manner the ability of students to the differences between different levels of feedback and help them. When students start the discussion, I take the initiative to go to express difficult or courageous which small groups of students, guide and encourage them to tell the hearts want to say. In the summary after the discussion, ask them to answer some of the problems have been resolved some of the simple, gradually build confidence.
truly student-centered teaching ideas and teaching practice is a cyclical process of rising above think, do, feel only my teaching practice in a small attempt, the quality of education in the spring ready to get more opportunity to practice and is willing to humble to the cause of educational reform to make its own contribution. This article inappropriate invited the experts and teachers criticized the correction.
discussion method of teaching in geography skills
name of Hebei Province Zhimin
County high schools to discuss experimental method is a student-centered activities in their own teaching methods. If a reasonable discussion method used, the classroom is the stage of active learning, classroom to become a student of positive thinking, wisdom flash of inspiration place. If the use of Debu appropriate, classroom teachers will become the stage monologue.
one to discuss the contents of the class discussion to select the right
is a problem and show the phenomenon of teachers to guide students to express their views or argument. To get the students have to say, an arguable, there insights to discuss the choice of topics should be carefully planned, well thought-off, classroom time is limited, if it is granted a new lesson, discussion questions should not be too much, usually 2 -3 title is appropriate. discussion questions to be refined expression, tempting. subject to appropriate content, not beyond what they have learned, is not confined to existing knowledge, to maintain moderate difficulty.
Second, the timing of the discussion
class discussions to fully start the general situation to go through to set (or background rendering) - Free Discussion - express opinions - students summarize the four stages. To complete this process, teachers must give students adequate free discussion time, linked together, mobilize the enthusiasm of the students a real and inherent potential, so that the classroom may be heated arguments have led to the wonderful whimsy. to discuss what you really need long time, there is no set number, the teacher should flexibility, as the case. but if we can do the following prior work, class discussions can not only save time, but also to ensure the effectiveness of the discussion.
of the discussions of the spatial organization of the discussion should take at least two reasonable
individual, the classroom model for fixed, said the space to discuss the form of two commonly used at the same table, or around, four discussion. Although the discussion is only the form of spatial organization, but the spatial arrangement are reasonable, it can mobilize the initiative and enthusiasm of students . If we can discuss arrangements for u-space, or spatial organization are free to change, it is more improved. In short, the spatial organization should be conducive to enthusiastic participation of all students, should be beneficial to highlight the brilliant speech.
four to discuss the composition of staff
to be flexible under normal circumstances, the composition of discussion groups are free to staff, usually at the same table, the students around, with discussion. Of course, at the same table know each other before and after the harmonious relationship, may be able to cooperate happily and successfully complete the discussion of issues . But I found by observation, discussion groups following distinctive, often discussed in class to become hot zone. one of like-minded friends together to discuss, to speak their minds, the same point of view is easy; II, together with a discussion of male and female students , can stimulate the expression of individual desire; Third, there is active participation in discussion groups, can lead to rhythm, set off a national debate; four learning styles mix together to discuss complementary and can promote each other, Yangchangbuduan, can provide comprehensive view.
discuss personnel, teachers should also be actively involved, but the identity of the authority of teachers not to provide information, do not answer to the authority of the students are mistaken judgments, will not necessarily have to lead a pre-discussion definite conclusions. teachers often do, is to actively guide students center around the question to speak and to promote interaction among students, active play to the organizers, the role of regulator.
In summary, the discussion method use is conditional, it is necessary to consider the content of the right issues, but also to arrange your time, space, personnel, or even have to consider the discipline of the class, and student self-control and so on. Generally speaking, the teaching of the new phase of knowledge , in the basic skills training, when students not prepared in time, is not suitable for use discussion method.
heuristic history teaching Yongnian County, Hebei Province, along the south
towns compared the total school Xu Zhou
heuristic method of teaching is the soul of a variety of teaching methods, should permeate all aspects of the teaching activities, and implement the teaching process from beginning to end. Teachers model and the general requirements in a typical combination of teaching and guidance combined with the additional phase to the positive the principle of cooperation under the guidance may take the form of a variety of inspiration. heuristics in the form below to talk a bit superficial understanding.
one, is asking teachers to inspire the most commonly used is an inspiration in the form, that is based on teaching The focus on key issues raised enlightening. It is often the key place in the textbooks, the turning point and extended at the other proposed moderate difficulty also is conducive to the resonance between teachers and students. Meanwhile, we must refer to the students the correct way of thinking, analyzing problems from the correct position.
Second, it is instructive to ask the opposite question from the perspective of teachers or other point to ask questions, stimulate their thinking and deepen the students understanding of the nature of historical knowledge and train students with Marxist theory the ability to analyze and solve problems.
Third, inspired this observation is the use of pictures, objects, slides and video, such as enhanced visual image rendering ability of students to form a historical representation and thinking in images, and then coaching and inspiring teachers to explain the logic into the next so that students find out the laws or strengthen understanding of the nature of historical knowledge.
four scenarios inspired by this teacher agitation with noble emotion, fun and artistic language, or audio-visual means to render the atmosphere and heighten the theme of historical events or historical figures to life, the formation of a mood, to enhance emotional memory and enable students to receive education from.
V, reasoning is based on the historical development inspired the causal relations and internal relations, inspire students to logical reasoning, and draw valid conclusions.
VI is based on historical facts to determine enlightening, after pulling points, increased to reflect the understanding of the law of development of the height of things, to determine the historical conclusion is that with non.
seven, it is instructive to compare the corresponding two sides of an issue, or to compare different knowledge of history, through inspiration, so that students learn more about understanding of the connotation and extension of knowledge.
eight, inspired by analogy is a common property of some historical knowledge of classification, comparison, inspiring students to find similarities and differences, to enable students to accurately grasp the true meaning of historical knowledge. Meanwhile, to improve ability to identify great benefit of students.
nine, inspired by the convergence of certain historical facts is a comprehensive, through inspiration, come to logical conclusion, so that students understand the historical knowledge of the feelings to rational knowledge, access to deep , a strong concept or theory.
ten, the proliferation of inspiration is a problem-centered, multi-angle questions for students to layers of deep thinking, re-combination of knowledge, multi-access to knowledge, is the thinking of a variety of answers inspired form. It can develop students ability to work, but also can stimulate the enthusiasm of the students and the creative spirit. For example, say this issue through to a given problem, and guide students to think multi-enable students to firmly grasp the basics, and flexible use of learned knowledge, replicability, by analogy.
heuristic could take different forms, but in principle only A: that teachers play a leading role in the premise, fully mobilize the enthusiasm of the students, initiative and creativity, based on their mastery of knowledge, capacity and ideological education for the purpose.
the wisdom of building the language classroom
Solid Zhen Ping County, Hebei Province wide central school curriculum
PATHOLOGY expected life of the classroom should be met, the mind similar to the classroom, is Zhiyiwennan place, the truth is through dialogue to explore the place. This class is a complex, dynamically generated, it is always in the ordered and disordered development of the integration. Therefore, today's educational needs of our personnel to construct, with the wisdom to practice.
you how to play the educational wisdom of constructing a new language class do?
one, with the wisdom Optimize Teaching Design
instructional design blueprint for classroom teaching. Optimize Teaching Design, it is necessary to ascertain a thorough understanding of course content and learning on the basis of the situation, seize the few entry point:
(a) of the inventive, the creation of the new situation.
We often have such a feeling: a many times on old texts, seems to have been hard to dig out new ideas, but some people still can Off the beaten track, the old text on a new level. Creative instructional design is always the charm.
(b) of the discerning, digging training points.
target language class should be implemented in the ontology language of the text experience on the perception . superficial learning a language should not have a large area of Our language classroom presents a different kind of exciting.
(c) imaginative, design development practice.
to expand our practice in the language classroom nowadays is very common. We see the expansion of good practice can be timely focus for the break, and resolve difficult service; good development practice to develop the students thinking, and promote the use of knowledge transfer; good design practice to expand flashing brilliant teacher of wisdom.
Second, with the wisdom to control the language classroom.
sway talented classroom teachers and the wisdom of the stage. classroom teachers is a complex challenge, it is dynamically generated and can create many exciting moments.
(a) random clever Reviews
Teachers timely and appropriate reviews, they are trying to dialogue with the soul is thought the collision sparks, but also the wisdom to lead a higher level. We should develop intelligent, distinctive language assessment for students while in the mental and physical pleasure crops and inspiration.
(b) take advantage of the opportunity generation
Health and development process, classroom teaching is the ever-changing, and resourcefulness of teachers is actually a kind of mental art is long out of practice teaching practice.
(c) to calmly deal with
a teacher of wisdom, to capture opportunities from the embarrassment, of mediocre to wonderful, miraculous, educating people play the harmonious melody. on the classroom a species reflects the profound cultural literacy.
In short, the language which is full of ideas, full of spirit, full of wisdom of the discipline. The classroom is a more challenging place full of wisdom. language education as an art of existence, does have its the unique magic of amazing. which is what we as educators need to continue the pursuit of a thing.

Dan Guangling
a successful high school physical education, whether it is the usual classroom teaching or teaching and research courses, race courses, should be Three Smiles essential, but the focus here to discuss the use of teaching methods are not correct or not, but how to play to the characteristics of existing materials to make teaching more with fun, active classroom atmosphere. In general, we like to choose their own familiar or the implementation of the contents of good teaching, it will be more handy. But Select the rhythm of male teachers may be teaching activities, or the content of female teachers face football and so on. At this time we are required to find and use features to create classroom materials on the br> students are teaching the subjects, must give full play to their main role, from passive acceptance to active learning. To make the students in the classroom, praise, less criticism, teachers too serious, will inevitably produce a sense of distance and the students a sense of fear, if the first reaction of the students finish the exercise is to observe teachers face during practice and not feel the satisfaction, then the student will always are let them think demonstration, explanation is the most accurate infected students. but beyond that, teachers should also not be pro-mei, get along with, willing to work with teachers, with the completion of teaching tasks.
teachers and students more intimate. on the part of the game in this class, when the first pass after the game finished, winning cheers from a group of not very warm, when the end of the game with the second time, I side direction to the team, while made to them to be cheering the I deliberately shook his head and said:
in the classroom teaching, adequate preparation is the foundation, in the classroom to do the unique new idea, any one class would be the best.

It helps to highlight the structure and function, form a unified structure and living environment and enhance the knowledge of the inner links and highlights the evolutionary point of view, so that students easily identify, understand, remember and master. both vertical comparisons but also horizontal comparison, through the systematic analysis and comparison of different categories and summarized the similarities and biological characteristics, the biology of learning from hard shift, simplify.
optimize the development of mathematics teaching thinking skills of students
Hebei County Canton Province Canton City School Shi Lanyu Pingjhen
Central School is both a controlled process of teaching the process of information flow, the task is completed the main way of teaching mathematics. on the formation of the teaching process optimization of various structural control and regulation system , it is a large area to improve the quality of primary school mathematics teaching the key. Therefore, as in the leading role in the process of teaching teachers, with particular emphasis on optimizing the development of mathematics teaching one student's thinking ability
, motivational, the quality of students thought the intention
direct promotion of human motivation is internal motivation of the activities and power, the psychologist Bruner to personality, his activities are dominated by interest in all the activities to be effective for a certain interest in a prerequisite. interested can generate motivation, student learning is one of the important sources of power, with interest, teaching to achieve good effect.
Second, increasing entropy with information to enhance the density
to stimulate thinking, thinking, activities must be effective control of the process of teaching a planned and purposeful transfer of information with entropy, to improve the density of thinking.
1. to the internal language students to think independently. mathematics teaching, students can give full play to make learning initiative, which requires teachers to students as thinking requires, but also to leave some space for students to think independently. In teaching students to think about and then do it. to enable students to speech and action control to gradually play a conscious role in promoting the thinking of the inner speech to promote logical thinking capabilities of students. modern education concept that mathematics teaching is the teaching of mathematics activities, namely, the teaching of thinking activity. Language is usually thought of thinking is the language of shell hh shown as the carrier. the student's cognitive law school students with the operation, the hands should, think for the expression of dynamic combination of mouth, that is, from the logical thinking. the main thinking things are good at different levels in the vertical and horizontal two aspects of development, to the depth and breadth of development issues to achieve a comprehensive understanding of things. To this end, teachers should pay attention to the process of teaching in mathematics to reveal mathematical essence of the problem, to help students improve their thinking ability concise. In problem-solving process, the first overall analysis of the issues, build mathematical models of thinking, and then outside to the inside, revealing the essence of problems. when the problem tends to resolve after from here, a systematic study related issues, so that you can solve a problem for solving a class of problems, that analogy. to question the application of training, for example, teachers should be good from the horizontal, vertical, reverse, multi-level system , the evolution of multi-up, expand, deepen, in order to improve mathematics teaching in the density and capacity. are the only way to achieve not increase the burden on students, but also the purpose of improving teaching quality.
optimize the mathematics classroom teaching, development thinking ability of students, teaching objectives must be clear, focused teaching, teaching methods and reasonable in order to ensure teaching effectiveness and reduce the heavy burden of students to implement.
how to improve the plug-speak, write, then teaching
Hebei Qiuxian Center School Liuzeng Jun
Nanxincun shop now language teaching, learning and more emphasis in the text for students to explore the main angle, in fact, pay more attention to the process of writing and pay attention to the main body of students a sense, become the passive subject traction to the idea of active extension. From the Process of writing instruction, to establish the status of students, students living in close contact, attention to the role of emotional power, it is an important guiding principle. in the composition process of teaching teachers to stimulate student life, learning memory the basis of emotion into the teachers to enable students to create scenarios, scenarios linked together, encouraging students to express the idea of an orderly end to form the text for the results.

This is formed into the atmosphere different. Although Figure meaning is obvious, but let the children speak out is not easy. I designed Some links and take advantage of causal factors to stimulate students to think and express enthusiasm, let them say to each other, said that in public.
III. full praise, attention to composition class of all those heads at
flexible, open-minded The students are the most active, because they first read map views, clear thinking, a more accurate expression of confidence is also very full. In contrast to those thinking more slowly, not very well express less confidence in the students, always fear of students and teachers because of the error is ridiculed. so full attention to writing in the teaching experience of all students, in a timely manner the ability of students to the differences between different levels of feedback and help them. When students start the discussion, I take the initiative to go to express difficult or courageous which small groups of students, guide and encourage them to tell the hearts want to say. In the summary after the discussion, ask them to answer some of the problems have been resolved some of the simple, gradually build confidence.
truly student-centered teaching ideas and teaching practice is a cyclical process of rising above think, do, feel only my teaching practice in a small attempt, the quality of education in the spring ready to get more opportunity to practice and is willing to humble to the cause of educational reform to make its own contribution.

discussion method of teaching in geography skills
name of Hebei Province Zhimin
County high schools to discuss experimental method is a student-centered activities in their own teaching methods. If a reasonable discussion method used, the classroom is the stage of active learning, classroom to become a student of positive thinking, wisdom flash of inspiration place. If the use of Debu appropriate, classroom teachers will become the stage monologue.
one to discuss the contents of the class discussion to select the right
is a problem and show the phenomenon of teachers to guide students to express their views or argument. To get the students have to say, an arguable, there insights to discuss the choice of topics should be carefully planned, well thought-off, classroom time is limited, if it is granted a new lesson, discussion questions should not be too much, usually 2 -3 title is appropriate. discussion questions to be refined expression, tempting. subject to appropriate content, not beyond what they have learned, is not confined to existing knowledge, to maintain moderate difficulty.
Second, the timing of the discussion
class discussions to fully start the general situation to go through to set (or background rendering) - Free Discussion - express opinions - students summarize the four stages. To complete this process, teachers must give students adequate free discussion time, linked together, mobilize the enthusiasm of the students a real and inherent potential, so that the classroom may be heated arguments have led to the wonderful whimsy. to discuss what you really need long time, there is no set number, the teacher should flexibility, as the case. but if we can do the following prior work, class discussions can not only save time, but also to ensure the effectiveness of the discussion.
of the discussions of the spatial organization of the discussion should take at least two reasonable
individual, the classroom model for fixed, said the space to discuss the form of two commonly used at the same table, or around, four discussion. Although the discussion is only the form of spatial organization, but the spatial arrangement are reasonable, it can mobilize the initiative and enthusiasm of students . If we can discuss arrangements for u-space, or spatial organization are free to change, it is more improved. In short, the spatial organization should be conducive to enthusiastic participation of all students, should be beneficial to highlight the brilliant speech.
four to discuss the composition of staff
to be flexible under normal circumstances, the composition of discussion groups are free to staff, usually at the same table, the students around, with discussion. Of course, at the same table know each other before and after the harmonious relationship, may be able to cooperate happily and successfully complete the discussion of issues . But I found by observation, discussion groups following distinctive, often discussed in class to become hot zone. one of like-minded friends together to discuss, to speak their minds, the same point of view is easy; II, together with a discussion of male and female students , can stimulate the expression of individual desire; Third, there is active participation in discussion groups, can lead to rhythm, set off a national debate; four learning styles mix together to discuss complementary and can promote each other, Yangchangbuduan, can provide comprehensive view.
discuss personnel, teachers should also be actively involved, but the identity of the authority of teachers not to provide information, do not answer to the authority of the students are mistaken judgments, will not necessarily have to lead a pre-discussion definite conclusions. teachers often do, is to actively guide students center around the question to speak and to promote interaction among students, active play to the organizers, the role of regulator.
In summary, the discussion method use is conditional, it is necessary to consider the content of the right issues, but also to arrange your time, space, personnel, or even have to consider the discipline of the class, and student self-control and so on. Generally speaking, the teaching of the new phase of knowledge , in the basic skills training, when students not prepared in time, is not suitable for use discussion method.
heuristic history teaching Yongnian County, Hebei Province, along the south
towns compared the total school Xu Zhou
heuristic method of teaching is the soul of a variety of teaching methods, should permeate all aspects of the teaching activities, and implement the teaching process from beginning to end. Teachers model and the general requirements in a typical combination of teaching and guidance combined with the additional phase to the positive the principle of cooperation under the guidance may take the form of a variety of inspiration. heuristics in the form below to talk a bit superficial understanding.
one, is asking teachers to inspire the most commonly used is an inspiration in the form, that is based on teaching The focus on key issues raised enlightening. It is often the key place in the textbooks, the turning point and extended at the other proposed moderate difficulty also is conducive to the resonance between teachers and students. Meanwhile, we must refer to the students the correct way of thinking, analyzing problems from the correct position.
Second, it is instructive to ask the opposite question from the perspective of teachers or other point to ask questions, stimulate their thinking and deepen the students understanding of the nature of historical knowledge and train students with Marxist theory the ability to analyze and solve problems.
Third, inspired this observation is the use of pictures, objects, slides and video, such as enhanced visual image rendering ability of students to form a historical representation and thinking in images, and then coaching and inspiring teachers to explain the logic into the next so that students find out the laws or strengthen understanding of the nature of historical knowledge.
four scenarios inspired by this teacher agitation with noble emotion, fun and artistic language, or audio-visual means to render the atmosphere and heighten the theme of historical events or historical figures to life, the formation of a mood, to enhance emotional memory and enable students to receive education from.
V, reasoning is based on the historical development inspired the causal relations and internal relations, inspire students to logical reasoning, and draw valid conclusions.
VI is based on historical facts to determine enlightening, after pulling points, increased to reflect the understanding of the law of development of the height of things, to determine the historical conclusion is that with non.
seven, it is instructive to compare the corresponding two sides of an issue, or to compare different knowledge of history, through inspiration, so that students learn more about understanding of the connotation and extension of knowledge.
eight, inspired by analogy is a common property of some historical knowledge of classification, comparison, inspiring students to find similarities and differences, to enable students to accurately grasp the true meaning of historical knowledge. Meanwhile, to improve ability to identify great benefit of students.
nine, inspired by the convergence of certain historical facts is a comprehensive, through inspiration, come to logical conclusion, so that students understand the historical knowledge of the feelings to rational knowledge, access to deep , a strong concept or theory.
ten, the proliferation of inspiration is a problem-centered, multi-angle questions for students to layers of deep thinking, re-combination of knowledge, multi-access to knowledge, is the thinking of a variety of answers inspired form. It can develop students ability to work, but also can stimulate the enthusiasm of the students and the creative spirit. For example, say this issue through to a given problem, and guide students to think multi-enable students to firmly grasp the basics, and flexible use of learned knowledge, replicability, by analogy.
heuristic could take different forms, but in principle only A: that teachers play a leading role in the premise, fully mobilize the enthusiasm of the students, initiative and creativity, based on their mastery of knowledge, capacity and ideological education for the purpose.
