A Study On The Teaching Practice Of Junior High School Physics Based On The Concept Of "Interdisciplinary Practice"

In April 2022,the Ministry of Education issued the Physics Curriculum Standards for Compulsory Education(hereinafter referred to as "the 2022 version of the curriculum standards"),which defines "interdisciplinary practice" as one of the primary themes of the curriculum content,under which three secondary themes of "Physics and daily life","Physics and engineering practice" and "Physics and social development" are established.Physics and Daily Life","Physics and Engineering Practice" and "Physics and Social Development",which require at least 10% of the total lesson time for teaching physics.The aim is to develop students’ interdisciplinary skills,their ability to apply knowledge to analyse and solve problems and to develop their creative thinking."Interdisciplinary practice" is a brand new theme in the 2022 edition of the Curriculum,which is a concrete expression of the proposal in the Compulsory Education Curriculum Programme(2022 edition)to"strengthen curriculum integration and focus on linkages".This is a concrete manifestation of the proposal of the Compulsory Education Curriculum Programme(2022 Edition)to"strengthen curriculum alignment and focus on connections".Therefore,this study is based on the concept of "interdisciplinary practice" in the design of junior high school physics teaching,aiming to provide reference cases and implementation methods for front-line teachers to carry out interdisciplinary practice activities in the future.This study defines the concept of "interdisciplinary practice" based on literature and related books,and identifies the target of the study;proposes a strategy for selecting the theme of interdisciplinary practice activities,taking the Shanghai-Yue version of the Year 8Physics textbook as an example,and combing the content of the standard with the contents of the textbook to find out the contents of the theme suitable for interdisciplinary practice activities;identifies the principles of teaching design as subjectivity,integration,practicality and Micro-crossover design.The design process is based on the concept of "interdisciplinary practice" : formulation of an authentic problem-design and implementation of a solution-testing and optimisation-presentation and communication of results.-Presentation and exchange of results.Finally,a case study is designed and implemented according to the teaching process.In this study,the teaching practice of "Craftsmanship spirit,making steelyard" was used as an example,and the effectiveness of the teaching was analysed using questionnaires and student interviews: according to the satisfaction questionnaire,83.3% of the students expressed their willingness to continue learning physics in the form of interdisciplinary practical activities in the future.The problem-solving skills of the students were analysed using SPSS 21.0 and there was a significant difference in their problem-solving skills before and after the teaching(t=-2.857<0,p=0.007),so the interdisciplinary practical activities were able to stimulate students’ interest and develop their skills.In summary,the design of my teaching cases based on the theoretical study of the concept of "interdisciplinary practice" is practical and operational,and provides some reference value for the implementation of interdisciplinary practice activities in secondary school physics teaching.
