Research On The Teaching Of Mathematics Learning In Junior High School Based On Mind Map

The exercises course of middle school mathematics can deepen and consolidate students' understanding of the learned knowledge,exercise students' mathematical thinking ability,and echo with the new teaching.It plays a role of secondary consolidation,and can also be used as a means of evaluation to prompt students to find out and fill in the gaps in time,so that teachers can make clear the weak points of students' knowledge,and then carry out targeted teaching.Through literature review,it is found that there are some problems in the current junior middle school mathematics exercise teaching,such as the old teaching concept of some teachers,students are not interested in the exercise class,the teacher's topic selection is not typical enough,the teaching method is relatively simple,the lack of attention to the students' subjectivity status,and the effect of the exercise class is not good.And mind map has the characteristics of visualization and structure,which matches with mathematical thinking.It is helpful for students to establish knowledge network and strengthen the relationship between knowledge when it is applied to the teaching of mathematical exercises.Therefore,this paper intends to explore the application of mind map in junior middle school mathematics exercises teaching.This paper intends to solve the following three problems:(1)to investigate the current situation of junior high school mathematics exercise teaching;(2)to construct the teaching mode of junior high school mathematics exercise based on mind map;(3)to carry out the experimental research of junior high school mathematics exercise teaching based on mind map,and to explore the effectiveness of the teaching mode.First of all,using the method of questionnaire to investigate the current situation of junior middle school mathematics exercises teaching,the research finds that there are the following problems in the exercises class at this stage:(1)the teacher's preparation before the exercises class is not enough,some teachers have no lesson plans for the exercises class,and the selection of the exercises is relatively random;(2)the way of explanation of the exercises is not scientific enough,and the arrangement of the exercises is not reasonable;(3)the students' further reflection after exercise class is not enough,and their ability to solve problems is limited.Secondly,on the basis of relevant theoretical analysis and thinking,the paper constructs the teaching mode of junior middle school mathematics exercises based on mind map,which includes pre class preparation,classroom teaching,consolidation after class.The pre class preparation includes teachers' activities and students' activities.the teacher's activities are as follows:(1)define the teaching objectives,sort out the key and difficult points in teaching;(2)draw the mind map;(3)select the exercises;(4)solve the questions and mark the knowledge points;(5)establish the compound mind map.Students' activities are as follows:(1)review and sort out knowledge points;(2)draw the mind map;(3)solve the problems and mark the knowledge points.The classroom teaching is divided into seven parts:(1)guide students to improve the mind map;(2)guide students to improve the marking of knowledge points;(3)review knowledge points according to the logical sequence of mind map;(4)explain the exercises under the corresponding knowledge points;(5)summarize and review the corresponding knowledge points and their applications;(6)mark the exercise information in mind map,and gradually establish a composite mind map(7)review and summarize the composite mind map.The third link to the seventh link is the cycle link,and the judgment condition is whether all knowledge points have been reviewed.After class consolidation is mainly to apply the compound mind map established in the class to the follow-up learning.Finally,two classes with the same basic level of mathematics are selected to conduct a experimental research,one is the experimental class and the other is the control class.The experimental research of junior middle school mathematics exercises teaching based on mind map is carried out to explore the effectiveness of the teaching mode of exercises.The results show that the performance of the experimental class is significantly higher than that of the control class,which means that the teaching mode based on mind map is effective.
