Investigation And Countermeasures Research On Teaching Present Situation Of Mathematics Unit Review Lesson In Junior Middle School

The first question to be paid attention to in the unit review class teaching is how to get rid of the teaching constraints of reciprocating lessons in the unit review class,and unify the knowledge structure,mathematical basic principles,mathematical problem solving methods and mathematical ideas into an organic whole,which is beneficial to Students' understanding of the relationship between mathematics knowledge goes further,and it is also more conducive to the development of students' mathematical thinking,and thus enhances the core literacy of mathematics.In view of the problems existing in the junior high school mathematics unit review class,the author first conducted a questionnaire survey of students and teachers and interviews with teachers.Secondly,in order to find the status quo of changing the junior high school mathematics unit review class,read and deeply analyze the relevant literature.Research,combined with existing research experience at home and abroad,to express their own views.Through investigation,it is found that the current situation of junior high school mathematics unit review class teaching is explained from two aspects:(1)from the perspective of students' level: students are lack of enthusiasm for unit review lessons,lack of initiative in unit review,lack of planning and timely review;The mathematics unit review class is the exercise class or the examination paper explains the evaluation class and the topic lacks the bright administrative level and the gradient which should have,the mathematics unit review method is quite simple.(2)from the perspective of the level of teachers,the overall concept of teachers is weak,the teaching mode of mathematics unit review lesson is single,and the teaching effect of mathematics unit review lesson is not good.Based on the results of the survey and interview,this study analyzes and proposes relevant strategies as follows :(1)change teachers' ideas and fully realize the value and function of unit review lesson;(2)improving teaching methods;(3)strengthen the training of comprehensive questions and focus on reflection;(4)improve the overall concept of teachers;(5)improve students' ability to edit questions by themselves.According to these strategies,the overall teaching design of this chapter is carried out in accordance with the teaching mode of “vertical combing of knowledge,horizontal communication of knowledge,infiltration of mathematical thinking and comprehensive application”,hoping to provide some help for front-line teachers.
