Study On The Geometry Review Lesson Of "Perimeter And Area" In Primary School

Geometry teaching is an important part of mathematics education in primary school,which plays an important role in review course of mathematics teaching in primary school.It makes student consolidate and strengthen the knowledge that they have learned to solves the combine problem of the relation among spot and line and surface by summarizing and arranging geometry knowledge in different stages.At present,the teaching research on geometry in the education industry mainly focuses on the field of new teaching course,and seldom focuses on geometry review course.The geometry review course is composed by students,teachers and the review knowledge so this research focuses on three elements to analyze that Taking the perimeter and area knowledge points of basic geometric figures as the teaching carrier of review class,the three problems are studied respectively through three typical geometry review classes,which are that No.1: What is the relationship between exercises design and students' effective learning behavior in geometry review class? No.2: What are the effective review methods for teachers in geometry review class? And No.3: How does the knowledge of geometry review penetrate into the cultivation of students' mathematical core literacy?In the research on the relationship between exercise design and students' effective learning behavior,I mainly use the method of observation in field to study the participation and effectiveness of students' effective in learning behavior in the classroom.Through the design of observation form and observation records in the whole process of the classroom,finally collected the analysis record data to research and draw conclusions.In the research of teachers' effective review methods,we mainly use the method of after-class questionnaire survey.Under the method of teachers' differentiated review teaching,we investigate the degree of students' receiving knowledge.We design the questionnaire and collect the information of students' receiving knowledge according to the two ways of subjective and objective evaluation.At last,we make a summary analysis and research to make the conclusion;In the aspect of how to infiltrate the review knowledge into the research in mathematics core literacy,we mainly use the interviewmethod of teachers to evaluate the cultivation of mathematics core literacy,and design the interview outline to interview several teachers in teaching,and finally collect and summarize the interview evaluation to make the conclusions.Through analysis and research,the following conclusions have been made on three issues as below:1)Whether the exercises are designed properly directly affects the students' effective learning behavior.Only when the "Three Focuses" are achieved,can the effectiveness of the students' learning behavior be improved;2)The core of review teaching is to focus on the combination of knowledge fragmentation and systematic review.The effective review methods include three types: heuristic education of teachers,variable teaching and systematic review;3)The cultivation of students' core literacy should be combined with the integration and penetration of review knowledge points.First,we should create a good classroom learning atmosphere,secondly,we should carry out ingenious exercise design,and thirdly,we should pay attention to the life-oriented design of teaching exercise.In the end,We put forward the three teaching suggestions for geometry review class in primary school.
