"Interdisciplinary Practice" Theme Teaching Research Of Junior Physics

With the development of economic globalisation,all governments want to enhance comprehensive national power through education reform,so as to improve national core competitiveness.China’s Compulsory Education Curriculum Programme(2022 Edition)clearly puts forward the basic principles of "strengthening curriculum integration and focusing on correlation" and "changing the way of educating people and highlighting practice",requiring at least 10% of the lesson time of each subject curriculum to be devoted to the theme of "interdisciplinary practice" is to be studied.The Physics Curriculum for Compulsory Education(2022 Edition)therefore includes an important new level 1 theme of "interdisciplinary practice",which is based on innovation and comprehensiveness and requires students to apply their subject knowledge to solve real-life problems,to "learn by doing","learn by using" and "learn by creating",in order to enhance the overall quality of students and to nurture the talents needed by the country.The main research elements of this thesis are as follows:Firstly,the thesis provides a systematic overview of the current situation and development process of interdisciplinary teaching at home and abroad,defines the concept of "interdisciplinary practice",interprets the characteristics,content requirements and academic requirements of the subject of "interdisciplinary practice" in the curriculum,and clarifies the connotation of the subject of "interdisciplinary practice".Secondly,in order to understand the difficulties and needs of front-line junior secondary physics teachers in teaching the theme of "interdisciplinary practice",the thesis conducted questionnaires and interviews,analysed the survey data and summarised the findings.The results of this part of the research and analysis provide a practical basis for the development of subsequent teaching strategies and the design of teaching cases.Thirdly,the thesis gives strategies and suggestions for teaching "interdisciplinary practice" in junior high school physics from three dimensions: topic selection,planning and implementation,and evaluation.In the dimension of topic selection,the thesis gives materials for teaching the theme of "interdisciplinary practice" under three secondary themes and discusses the entry point for the selection of "interdisciplinary practice" from the perspective of the analysis of the learning situation.In the dimension of planning and implementation,the thesis provides teaching strategies and recommendations for "interdisciplinary practice" in terms of teaching objectives,planning programmes and practice processes.In the evaluation dimension,the thesis constructs a pluralistic evaluation system from three aspects of subject diversification,content multidimensionality and method diversification,and gives specific teaching strategies and suggestions.The thesis enriches the implementation of "interdisciplinary practice" through strategies and recommendations in the three dimensions mentioned above.Finally,the thesis designs teaching cases for each of the three "interdisciplinary practice" secondary themes in the curriculum.In terms of physics and everyday life,a case study on "From Myopic to Telescopic" was designed,with three lessons and eight tasks,including the construction of a junior high school optics system,vision correction and the making of a model camera.In terms of physics and engineering practice,a teaching case of "Ubiquitous Forces" has been designed,with a total of 3 lessons and 6 tasks,including the construction of a junior high school mechanics system and the making of a spring force gauge.In terms of physics and social development,a teaching case of "Environmental Protection in Action" has been designed,with a total of 2 lessons and 4 tasks,including the construction of a physical concept of energy transformation and transfer,and an investigation report session.The design of this part of the teaching case focuses on the development of students’ core literacies and provides a rich source of material for frontline teachers to carry out "interdisciplinary practice" thematic teaching,making up for the lack of "interdisciplinary practice" cases.This thesis takes the theme of ’interdisciplinary practice’ as its research topic.Through questionnaires and interviews,it analyses the current situation of teaching,proposes strategies and suggestions for teaching the theme of ’interdisciplinary practice’,and designs three teaching cases,which are of great significance for the in-depth understanding and effective implementation of the theme of ’interdisciplinary practice’.
