Action Research Of Feynman Learning Method Applied To The Mathematics Review Class In Junior Three ——Taking Quadratic Function Teaching As An Example

As an important form of classroom teaching in junior three,review class plays a key role in helping students sort out the knowledge they have learned,form a knowledge framework,improve mathematical thinking,clarify thinking methods,and improve the efficiency of problem solving.In order to improve the review efficiency,teachers must change the cramming-style teaching and give full play to the subjective initiative of students.Feynman learning method is an efficient learning method.It can help people grasp concepts,methods or knowledge quickly,clearly and accurately.Therefore,this paper tries to integrate Feynman learning method into mathematics review class of junior three,so as to construct a more efficient review teaching mode.This study intends to solve the following three problems: 1.How is the development of mathematics review course in grade three? 2.How to carry out math review lessons in junior three under the guidance of Feynman learning method? 3.Is it effective to integrate Feynman learning method into math review lessons of junior three?This research selects part of grade 3 students from a middle school in Chongqing as the research object to carry out action research.Before the teaching action was carried out,the author used the questionnaire survey method to understand the current situation of the mathematics review course in junior three,and analyzed the problems existing in the mathematics review course.Next,the author carried out two rounds of action research in the experimental class and the control class,respectively reviewed the algebraic maxima problem and the existence of right triangles in the comprehensive application of quadratic functions,and put forward two teaching cases.Finally,through the analysis of the students' pre-test and post-test scores and the analysis of the questionnaire,the author understands the changes of students' problem-solving ability,cognitive level and learning emotion.As for the first research question,the author found that the mathematics review courses in junior three are mostly "teacher full of lectures" or "combination of lectures and exercises".Students' attitude towards the review courses is not optimistic,their learning initiative is not strong,and their interest in mathematics learning is low.For the second research question,the author adjusted and innovated Feynman's learning method according to the requirements of the mathematics review course in junior three,and obtained the strategy of Feynman learning method applying to mathematics review course in junior three,including the pre-class preparation stage,classroom implementation stage and post-class improvement stage.The classroom implementation stage is divided into four links: link one is teacher guidance,with example to see the whole,link two is to teach to promote learning,discover blind spots,link three is to simulate teaching,show style,link four is summary condensed,thinking for progress.As for the third research question,the author found that the application of the Feynman learning method in the review class can significantly improve students' cognitive level and academic performance,help students improve learning attitude,and enhance their review confidence.
