Investigation And Research On The Version Of Beijing Normal University In Seventh Grade Mathematics Textbooks In Problem Situations (on) A

The Experimental Textbook Mathematics for Compulsory Education,based on the China’s mathematics’standards in2001,was published by Beijing Normal University. large numbers of problem situation be used in teaching materials, it is a new breakthrough in education reform. So whether the situation is beneficial to teaching, Teachers and students opinions are the same, Or what are the differences, What are the problem situation in the teaching material of the window and the insufficiency, These are issues worthy of study. So the problem situation in teaching materials to do the following several aspects of research:Through a lot of literature, mastered the theoretical knowledge about problem situation of certain principles, methods and setting question circumstances. Of problem situation concept, and to define the problem situation of this study, this article mainly problem situation in teaching material as the research starting point. Finally, through reading some related scholars on the research of the problem situation, understand the current situation of the problem situation and main problems.The author to Beijing normal university version (on) the seventh grade math textbooks as a starting point, In light of the problem situation, set up a certain principles, The author divided the problem situation in teaching materials into five categories:(1) real situation (2) the transition situation (3) to explore the situation (4) the game situation (5)false situation. For each problem situation and frequency of list, intuitive to see the proportion in the whole textbook.The author through the investigation in the form of questionnaire combined with depth interviews, Conducts the investigation and study for teachers and students respectively.Teachers and the students’ question in the questionnaire, some of the same, Purpose is to want to know in the two different groups of the same issues are consistent, The results found that, Students in the eyes of problem situation and teachers are not exactly the same. Such as students like the game class problem situation, While teachers think of such a situation is not conducive to teaching. There are part of the problem is not the same, Purpose is to want to interview, Understand their teaching some real ideas and Suggestions. Such as students feel problem situation can be very good to help them understand the knowledge, Just some problem situation like discount shopping situation is not easy to understand. Most teachers awareness of the problem situation is not enough, Only problem situation as the introduction of the content of the new lesson. Each relevant investigation made in the form of charts, So that readers can clearly know the difference and correlation.Finally the author combined with the teaching material analysis and the result of the investigation and study, This teaching material on "flash" and "deficiency" two aspects of the summary, Teaching materials of the problem situation more rich content, Involves the range is wide, Embodies the students as the main body of the teaching methods, Also left a very sufficient space to teachers’ teaching. But there are some shortage of place, On the way of the teaching material arrangement to use has risen in a spiral way, But the logic is not particularly close, Is not conducive to the formation of students’ logical thinking; In the transition of the teaching material content is not perfect, Knowledge is not compact; Some of the content expression not accurate enough, May bring inconvenience for this part of the learning; And the situation of setting transition or inappropriate, These are all need to improve, To further improve.In the end, The author respectively gives some Suggestions on teaching materials, teachers, teaching, The history of mathematics textbooks should add some problem situation, Penetration of mathematical culture appropriately, In present mathematical charm at the same time can promote students’ mathematical understanding; Teachers is mainly to improve their culture and the cultivation of quality, To be able to "creative, strategy use teaching material, The author also in this paper have certain cases, Help readers to understand some of my views; In the aspect of teaching,hope can mainly aimed at the problem situation in teaching material, Play a role of some of the problem situation, foster strengths and circumvent weaknesses, Effectively make good use of teaching materials made to some of the problem situation, Hope can have certain help for education reform.
