Using Mind Map To Optimize The Practice And Exploration Of The Junior High School Mathematics Lectures

In the study of mathematics in junior high school,students' solution of logarithm problem not only can directly reflect their understanding and mastery of mathematics knowledge,but also thinking ability.But in practice,many students can't solve mathematical problems easily,and they can't find the key to solving problems.All these because they can't grasp the knowledge well,or because of their single-mindedness etc.Therefore,mathematics exercises evaluation course is particularly important in junior high school.As a tool for thinking visualization,mind mapping is similar to the thinking way of the human brain.Therefore,Through the combination of theory and practice,this paper applies the mind maps in the middle school mathematics exercise evaluation class,in order to help the students to construct the knowledge system,to spread their thinking and to improve the teaching efficiency of the mathematics exercise evaluation class.In this paper,first of all,it summarized the general situation of research on thinking map and mathematical problem solving exercises at home and abroad by using the method of literature research.And it expounds the basic viewpoints of the brain science theory,schema theory,knowledge visualization theory and constructivism theory and the guidance of these theories to the study.At the same time,the reasons and advantages of applying thinking map to mathematics exercises evaluation class are analyzed.Secondly,by using the method of questionnaire,the student and the teacher were conducted a relevant questionnaire survey respectively,in order to understands and analyze the problems existing in the mathematics exercise evaluation course of the junior middle school at present;Thirdly,according to the existing problems,combined with the characteristics of the subject and the teaching content,the paper formulates the teaching steps of the mind map in the mathematics exercise evaluation class,applies the practical research,and uses the mind map in the actual teaching.Finally,through the questionnaire survey and student interview,the paper analyzed the results of practical research to test their application.The following conclusions are drawn from the study: it is feasible to use the mind maps in the teaching of mathematical exercises;Applying the mind maps can help students construct the knowledge system,improve problem-solving abilities and mathematics achievement,develop divergent thinking and inspire students' interest in learning and encourage students to actively study.
