Research On The Structural Characteristics And Avoidance Strategies Of Common Flawed Questions In Middle School Physics

Nowadays,the Ministry of education has issued many policy documents on "reducing the burden" for students and teachers,so that students can better return to campus and improve the level of homework management.To correctly understand the educational function of homework,we should not only control the total amount of homework,but also improve the quality of homework.Focusing on the physics homework of middle school students,we can find that the form of students' physics homework is mainly physics topics.As the basic unit of homework,the topic is of great value.By sorting out the common physics problems in recent years,it is found that some problems themselves are wrong,and even some defective problems frequently appear in the middle and college entrance examination papers,in the classroom and various learning materials.In advocating burden reduction today,this undoubtedly increases the burden on students and teachers in a disguised form,which is very different from the concept advocated by all sectors of society.This paper will summarize the common "defect problems" in middle school physics,clarify the problem structure,analyze the problems of wrong propositions,and put forward the corresponding avoidance strategies.This paper discusses three main problems: how to search the typical defects of concentrated physics.How to deeply analyze the error causes and structural characteristics of common defect problems in middle school physics according to the structural model.How to put forward corresponding avoidance strategies according to the research results of defect problems.In order to solve these three research problems,firstly,collect the common defect problems in middle school physics in recent years,read and study a large number of relevant literature,books and various examination papers,and sort out the problems and various answers;Secondly,analyze and sort out the relevant models of question type structure,and introduce the question type structure model selected in this paper;Thirdly,make a deep study of the collected defect problems,analyze the problem structure of the defect problems by using the analysis model,and point out the problem;Finally,it puts forward targeted avoidance strategies according to the existing problems.
