A Practical Study Of The Construction Of The Scientific Nature Of Physics Normal Students

High school physics curriculum standards clearly put forward: lead students to understand the nature of science.Physics teachers' understanding of the nature of science and their emphasis on the education of the nature of science are the key to the implementation of curriculum standards.As pre-service teachers,the construction of physics normal students' view of the nature of science is very important for their future career development.Firstly,this paper uses the literature research method to sort out the connotation of the nature of science,the research on the view of the nature of science of middle school students and pre-service teachers,the teaching strategies to construct the view of the nature of science,and the questionnaire measurement of the view of the nature of science.Based on the existing research results,eight dimensions of the view of the nature of science are summarized,and two groups of practice activities are used as teaching intervention to explore the impact of practice intervention on the construction of the view of the nature of science of normal physics students.Before the practice,VANSK scale was used to investigate the views of the nature of science of sophomore normal college students in a university in Nanjing.After that,normal university students participated in two practical activities.The first one was "tug-of-war with books",in which students were required to understand the physical principles through scientific inquiry steps and write practice reports after students' exploration.The second was a series of activities called "Science Caravan",which included several small experiments.Normal students participated in the production and explanation.After the activity,they accepted the interview.After the two activities,VANSK scale was used for investigation again,and SPSS software was used for pre-and post-test analysis.At the same time,practice report and interview content were analyzed.The results are as follows:1.Practical activities have a significant effect on the construction of normal physics students' view of the nature of science,and their scores in all dimensions have been improved.2.After the practical activities,the differences of normal physics students' views of the nature of science still exist in all dimensions,but the range of differences is reduced.3.It is found that there is no significant difference between normal physics students in the three aspects of practicality,creativity,social and cultural influence and penetration of science.Finally,the following suggestions are put forward on the construction of normal physics students' view of the nature of science:1.Increase the number of practical activities in teaching and promote the understanding of the nature of science in practice.2.In view of the weak points of students' view of the nature of science,the study of history of science should be interspersed with practice.3.Enrich the forms of practical activities and improve the cognitive level of the nature of science from different dimensions.4.To promote students' view of the nature of science from two aspects of practice and theory learning.
