The Application Of The Number Form Combining Idea In Countryside Junior Middle School

The number form combining idea is one of the most important mathematical ideas,unifying the two parts of mathematics: number and form.This paper mainly based on the countryside junior middle school,to explore the application of the number form combining idea in mathematics teaching.Based on lots of correlational studies,I chose research methods: investigation method,interview method and experimental method.In combination with the Study's background,I set up the following study questions: first,understanding the mathematics teaching current situation of using this idea in rural junior middle school.Second,study the influence on students' grade by permeating the idea;Third,study the influence on students' interest by permeating the idea.This study got to know current teaching situation of the idea in rural areas through investigation.The result of this investigation showed that the current teaching situation is not optimistic.The details as follow: Although mathematics teachers think the number form combining idea of mathematics learning is very important,they rarely penetrate the idea in the actual teaching;Students basically only heard this idea,and what the meaning of this idea is not clear;Many students can't draw the gform accuratly according to relationship between the numbers when they use the idea.According to the problems found in the questionnaire,the author studied the strategy combining with relevant theoretical knowledge.The specific strategies are permeating the number form combining idea in concept teaching,consolidating the idea in exploring solution teaching,applying the idea in problem-solving teaching,digging the idea in stage review.Based on the above research,the author has carried on the practice and to investigate the effect of practice analysis.Getting the following conclusion: first,the number form combining idea used in the countryside junior middle school mathematics teaching can improve students' math scores;second,the number form combining idea used in the countryside junior middle school mathematics teaching has greatly improved the students' interest in mathematics learning,and students began to actively take time study mathematics.Finally,I get the full-text conclusion,offering some teaching suggestions for mathematics teachers in class.
