Teaching Research On The Problem Of Dynamic Point In The Junior Middle School

In this paper,through the collection and collation of nearly five years of real problems in the cities of zhejiang province,it is found that more than 80% of the real problems in the real problems have a dynamic point problem,and most of them appear in the pressure axis of the12-point scale,which is enough to make them important.The dynamic point problem is widely used in the knowledge points of junior high school,which can be combined with the number axis,triangle,coordinate,quadrilateral,equation,function and so on.Because of this,the problem of dynamic point is very flexible and difficult,the students are not easy to understand and the scoring rate is very low.Because there is no unified,clear teaching standard and teaching method so far,the teaching of teachers has caused some problems.This paper designs a questionnaire survey based on the communication between students and front-line teachers to understand the students’ views and learning situation.I’ve divided into three chunks in the Settings of the questionnaire,and to increase the reliability of the student questionnaire,some of the questions are similar to the others;In order to make the students more intuitive to know what kind of topic is the moving point problem,so specially designed a geometry class action point problem to let the student prove.The survey was conducted on two different levels of schools in Wen zhou,with a total of 438 students from the eighth to ninth grade.Through the questionnaire data collection and analysis,find out the difficulties in students in learning and the learning theory of ausubel and constructivism theory,theory of poly a problem solving,and van hill theory as the foundation,according to zhejiang version of the eighth grade in the days of the knowledge and sums up exercises,devised a contains introduction,knowledge of teaching difficulty layer,and the teaching content always focus on the students are more confused about some of the type and scope of the concept of sports teaching cases.By the implementation of the teaching cases,the majority of students can be seen from the measured after compared with the teaching of the topic before no longer have a strong sense of fear,and can according to the problem solving steps and methods of the teacher,professor,in the original image annotation and write the number of related edge relationships,and carefully calculated.And a few of the students have been able to analyze the problems on their own,find the right,and use the terms of the title to solve the problem that’s a moderate level of difficulty.Through this study can help teachers realize the knowledge in which grade or plate last in action point problem teaching is appropriate,can also according to the knowledge of the concept of teaching for teachers to provide the certain reference value;It can also help students to have a deeper understanding of the problem of moving point,know how to find the entry point in the problem solving,and how to do the problem,which can greatly enhance the students’ learning confidence.
