A Study On Pre-service Physics Teachers' Ability To Analyze Problems Of Junior High School Students

Teaching of the physical exercises is an important part of physics teaching,which function can be summarized as: to enable students to clarify the vague physical concepts and rules or incorrect understanding;promoting and consolidating the formation of knowledge structure of physics;promoting the formation of solution structure;improving the accuracy and speed of solving problems;setting up creative thinking,cultivating creative the ability of solving problems.[1] Teachers can also have a more profound and clear understanding of the learning situation of the students to understand the situation of the students' knowledge.However,for the newly admitted students,who are lack of actual contact with students,often have an understanding with surface for the error of students.Even because of the universality of the problem,they ignore the effective information reflected in the students' exercise and usually explain the mistakes from students: "careless" and "wrong formula " "did not understand the concept " ······and for these "errors" hidden behind the information without further,resulting in teaching cannot be more effective and immediate.At the beginning of this study,through the questionnaire survey of pre-service and in-service teachers,we found that 97.05% of physics teachers think that the ability to analyze the students' exercise errors is a professional skill that teachers should possess And a good ability of error analysis,help teachers to carry out education and teaching work.Therefore,this paper based on the theory,focusing on the following three aspects of the research and preliminary investigation: 1)preservice teachers of junior high school students survey error analysis ability;2)effect of pre-service teachers' ability of error analysis of factor;3)Strategy of improving pre-service teachers' ability of error analysis.The error analysis of the concept of the ability of explanation,the author has referred to the Southwestern University Peng Aihui's PhD thesis,analysis ability to define mathematical errors: in order to ensure students' learning efficiency and success mathematics Teachers think students' errors as the object and identify,interpret,evaluate and correct those errors [2].This paper is based on the investigation of pre-service teachers to the students' physical exercises in the solution of the error as the object of thinking,and survey the teachers' ability of identification,interpretation,evaluation and correction of students' errors.Based on the investigation on the pre-service physics teachers in two normal universities of Southwestern University and Chongqing Normal University,the main conclusions are as follows:1)the present situation of junior middle school physics teachers' ability of error analysisThe ability of error analysis of physics teachers in junior high school is still in the stage of improvement,Its ability to analyze students' errors mainly lies in the incomplete analysis level,Most pre-service teachers are able to identify students' errors,but the ability to interpret,evaluate,and correct them is not enough.Mainly in: Teaching knowledge,Physics knowledge is not enough.most of pre-service teachers are not familiar with the teaching materials and syllabus,who can't Correct the error combined with the specific circumstances of the students and the focus of knowledge.2)Factors affecting junior high school physics teachers' ability of error analysisAccording to the feedback from the questionnaire and interview,we can see that the pre-service teachers think that the influence degree of each factor is different.Teachers' knowledge and teachers' beliefs are considered to be the two main factors that affect the pre-service teachers' ability of error analysis.3)Strategies for improving the ability of error analysis of junior high school physics teachersThere are two ways to improve the ability of error analysis of physics teachers in junior middle school:Internal cause: As the main body of the development of the error analysis ability,the pre-service teachers should have the consciousness and self-drive to improve their teaching ability.They should try their best to master the knowledge of physics,at the same time,they should learn the knowledge of pedagogy and psychology.Teaching skills,Putonghua,especially the logic of language that teachers should be further training.Pre-service physics teachers should be more with some excellent in-service teachers to learn,more contact with the high school students.knowledge from the practice is the most reliable.Colleges: It is necessary for colleges and universities to set up relevant courses for the training of pre-service teachers' ability of error analysis,especially to guide the pre-service teachers to identify,explain,evaluate and correct the errors of the students.In order to make the pre-service teachers have a preliminary understanding of the mistakes and mistakes made by the middle school students in the study of physics,they can improve their self-efficacy.
