Analysis Of Physics Classroom Teaching In Middle School Based On Nature Of Science

The research participants are physics teachers in the middle school,this research uses the questionnaire survey method to understand the present situation of the views about nature of science(NOS)of in-service physics teachers in some areas of our country.By analyzing regional differences,we can understand the gap between the physics teachers' view of NOS in our province and the developed regions(Shenzhen),and analyze the influence of gender,educational background,teaching age,professional titles and other variables on physics teachers' view of NOS.This paper uses the framework of NOS teaching analysis to make an example analysis of classroom teaching video.taking Newton's first law teaching content as an example,This paper analyzes the teacher's teaching behavior from the perspective of NOS,making a comparative study between the conventional class and open class,summarizing their differences,looks for the teaching behavior that effectively promotes the development of students' NOS,and provides a reference for the physics teachers in middle school to carry out scientific nature education.This paper is divided into six chapters: The first chapter is the introduction,which introduces the background and significance of the NOS education and the methods used in this thesis.The second chapter summarizes the development cognition of the concept of the NOS at home and abroad from the perspective of the development of philosophy of science,summarizes the research status of the NOS education from the point of view of teaching,and defines the related concepts.It is pointed out that the focus of this thesis is on the investigation of the view about NOS of middle school physics teachers and the analysis of teaching behaviors.The third chapter is the investigation of the present situation of the view about NOS of middle school physics teachers in some areas of China,the questionnaire is carried out on 119 in-service teachers and the data are processed by SPSS statistical software.The fourth chapter introduces the establishment of the framework of the NOS teaching analysis,the process of teaching video analysis and the use of related software.The fifth chapter takes the teaching video of "Newton's First Law" as the carrier,and selects the national middle school physics young teacher teaching competition,the reform innovation competition,the famous teacher teaching competition,in the conventional course teaching each two video lessons to make the lesson analysis and the contrast research.The sixth chapter is the research conclusions and prospects of this paper.Through the investigation,it is found that the middle school physics teachers in our province have a certain understanding of the NOS,but the level is not high;there is an imbalance in the cognitive level of the three dimensions of the NOS;compared with the developed regions(Shenzhen),the understanding of the dimension of scientific inquiry by physics teachers in middle schools in our province is significantly lower than that in developed regions,there is no significantdifference in gender,teaching age,professional title,academic qualifications and other variables.Through the sample video analysis,it is found that teachers adopt more implicit teaching methods in classroom teaching,but the explicit methods and reflective teaching strategies are not enough;In the process of teaching,the infiltration of the three dimensions of the NOS is uneven,and there are some defects in the education of the dimension of scientific cause.There is a phenomenon of simplifying the process of experimental inquiry in the regular classroom teaching;the teaching of the NOS needs a certain carrier,and teachers need to excavate the teaching content of the essence of science implied in the teaching materials.
