Practice Research On Teaching Of Mathematics Ideology Of Structure

The formation of the thought method of mathematical construction is formed in the teaching activities,gradually formed a kind of mathematical knowledge,it is an important mathematical thought method in middle school,but because of its implicit content,and has the characteristics of flexibility,in the actual teaching process met with a lot of difficulties and problems.Therefore,based on the importance of mathematical structural-thinking method and the difficulties in the teaching of mathematical structural-thinking method,this study is conducted in three aspects.Second,the teaching countermeasure of the thought method of mathematical construction;Third,the implementation of teaching cases and effect analysis.Constructional thought requires a high degree of flexibility in the mastery of knowledge,and students will encounter many difficulties in the application process.The reasons include not only the lack of solid mastery of knowledge,but also the defects of students' thinking ability.Therefore,the author conducted a test and interview analysis on the learning status and reasons of the thought and method of mathematical construction of middle school students.Second,students lack of good habits of thinking;Third,the students' abilit y to master and apply construction methods is weak.Then,this study adopts the survey method of interview to further analyze the reasons for this situation: 1.Students lack intuitive thinking and creative thinking;2.Students' psychological barriers affect their learning attitude;3.Students' cognitive structure is not perfect.In order to solve the existing problems,the author based on the construction of three periods of thought and method,respectively for the three periods of teaching countermeasures and teaching design practice.1.Cultivate thinking ability in teaching: from analogy association to processing and creation;From problem consciousness to inquiry consciousness.2.To introduce the characteristics and applications of mathematical structural thinking method in teaching: teaching countermeasures in the process of mathematical concept generation;Teaching countermeasures in the forming process of mathematical conclusion;Teaching countermeasures in the process of solving mathematical problems.3.Generalize the types and methods of construction in teaching: constructing algebraic models and geometric models.By using the class instance for students,teachers and the interview method,analyzes the teaching effect is obtained the following conclusion: the teaching of mathematical structural thought method,the main results are deepened students understanding of the structural thought method and mobilize the classroom atmosphere,improve the students' learning enthusiasm,cultivate the students' thinking ability.
