Research On The Application Of Mind Map In The Review Class Of Elementary School Mathematics Unit

Unit review is a basic course type of primary school mathematics classroom teaching.Effective unit review can improve students' overall cognition level of knowledge,systematize knowledge system and knowledge structure,and promote students to form optimal knowledge network and thinking network.However,the current primary school mathematics review class unit,the traditional classroom practice dull as ditch water,the sea tactical,it is difficult to attract the attention of students,especially the students is still in the first stage,due to the level of knowledge and ability to construct limited knowledge for observation,induction,summary,refining and combing ability of knowledge the structure of the low.Through the research on the application of the unit review course based on the mind map,the author explores the effective unit review.In this paper,brain science and knowledge visualization for scientific theory,based on Constructionist and effective learning education theory basis,try to change the research status of the first stage unit recitation of primary school mathematics review class,optimize teaching effect,structure system of knowledge construction,encourage students to actively participate in knowledge structure,promote students to form optimization knowledge network and network thinking.For teachers to teach unit review lesson,improve the teaching quality of unit review,provide the reference of teaching practice and the blueprint of teaching model.In this study,42 students in the second grade Qingdao Wenchang primary school class 2 as the experimental class,with 42 students in the second grade class 6 as the control class,to the second grade of Qingdao edtionupper volume "preliminary understanding" unit review lesson as the experimental content angle.In the experimental class 2,grade two,we used the creation of situations,sorting out the review--combing the Internet,the main body Internalization--the comprehensive application and the overall improvement.Before class,the students arrange the knowledge of this unit by thinking map,the teacher collects the students' works,and sums up the connotation of the students' combing of knowledge.To the classroom,the students exchange sufficient time for students to sort out the knowledge,go to student exchanges,deepen cooperation in;for students not easy to comb out the knowledge,through group cooperation,complement each other and arouse the students' thinking,in the process of communication,teachers to capture students the idea of "knowledge",will construct the knowledge module,so as to develop and improve the students' knowledge system.After the knowledge network is established and the knowledge system is clear,it is necessary to select the pertinent,open and effective exercises to improve the students' comprehensive ability.In the process of reviewing their knowledge points and combing the knowledge system,the students accumulate learning experience,perfect the thinking map,and improve the ability of combing knowledge.In the control class 6 classes of the second grade,the teacher adopts the traditional teaching mode,to review the knowledge-Standard Practice--Comment trap--a review of ascension to complete the unit review.In the teaching process,with groups of teachers also for the students' classroom language,knowledge system combing,exercise compliance and other aspects of the class monitor.From the data analysis,the results of the students in the experimental class are more stable,the gap between the students is relatively small and the students' achievements are more stable.Based on the experimental data,we analyzed students' basic knowledge mastery,flexibility and problem-solving ability based on mind map review unit.It provides optimization strategies for the application of mind map in the first learning unit review class,and personally goes through the carding and construction of knowledge system,forming a personalized review system,improving the effectiveness of self review,in order to promote the improvement of students' mathematics literacy.
