Current Situation Of Preview Of Physics In Junior Middle School Based On STSE Education Concept Investigation And Research

This paper studies the current situation and optimization strategies of junior middle school students integrating the concepts of science,technology,society and environment in physics preview.The purpose is to encourage students to connect textbook knowledge with science and technology,human society and living environment in preview,so as to broaden students' vision,enhance students' interest in learning and stimulate students' thirst for knowledge.Based on reading literature and professional books,the author comprehensively uses educational research methods such as literature method and questionnaire survey from five dimensions(Students' understanding of Physics,Students' Scientific Literacy,Students' understanding of STSE,Students' views on Preview,Students' views on Teachers' arrangement of preview tasks)designed the questionnaire,The author distributed and recovered the questionnaire to 511 students in grade 2 and grade 3 of the internship school,carefully analyzed the results of the questionnaire,and put forward countermeasures to solve the problems.Among them,the problem found in dimension I of the questionnaire is that some students are not very clear about the research object of physics and can not effectively distinguish between physics and other subjects,so they do not take targeted strategies to preview physics knowledge.The optimization strategy is: implement the problem oriented preview strategy integrating STSE and highlighting the characteristics of physics;The problem found in dimension 2 of the questionnaire is that students' mastery of the basic knowledge of physics is not reliable enough,and they do not establish an inevitable connection between the process and steps of scientific inquiry and the correct experimental results.The optimization strategy of the design is: implement the strategy of highlighting experimental exploration and consolidating basic knowledge preview integrating STSE;The problems found in dimension 3 of the questionnaire are: students do not pay high attention to science,technology,society and environmental problems,do not seek a deep understanding of the problems related to science,technology,society and environment that they cannot explain,lack of research spirit,and do not pursue the career of scientific researchers.The design optimization strategy is: implement the model demonstration and guidance of integrating STSE,combined with the group cooperation preview strategy;The problem found in dimension 4of the questionnaire is that students' self-awareness of preview is not high on the premise that teachers do not assign preview tasks.The optimization strategy of the design is to implement the exercise preview strategy of integrating STSE design to solve practical problems.The problem found in dimension 5 of the questionnaire is that the preview task assigned by teachers is relatively general,which only requires students to have the behavior of preview,and there is no clear requirement for the goal to be achieved,resulting in students' unclear purpose of preview.The optimization strategy of the design is to implement the task driven preview plan preview strategy of integrating STSE.Finally,based on the synthesis of various countermeasures,the author designs a preview scheme integrating STSE elements,in order to expand students' vision to the greatest extent and stimulate students' interest in learning physics,so as to help students achieve the purpose of using what they have learned and applying what they have learned,promote students to combine learning with production practice,move towards society in the future,and contribute to the consolidation and development of China's modernization and socialism with characteristics.
