Case Design And Practice Of Teaching Chemistry In Junior High School Based On Interdisciplinary Integration

With the development of society’s need for all-round talents and the deepening of the new curriculum reform,students’ interdisciplinary learning ability has also been put forward to higher requirements.2022 edition of the compulsory education chemistry curriculum standards clearly put forward the need to carry out interdisciplinary practical activities and infiltrate students’ existing life experiences and knowledge of other disciplines into the chemistry classroom.Interdisciplinary teaching has become a hot issue of current research,but the literature involving the front line of basic education is relatively small and has greater research significance.In order to understand the current situation and development trend of research on interdisciplinary and transdisciplinary teaching,to clarify the research direction and significance of this topic,and to take the principle of unity consciousness and the psychological principle of humanistic psychology,constructivist learning theory,pragmatic education theory,and learning migration theory as the guiding ideology,domestic and foreign literature were analyzed.The questionnaire survey and data analysis revealed that there are problems such as junior high school students’ lack of in-depth knowledge about the connection between subjects,and teachers’ failure to commonly use interdisciplinary integration in a variety of lesson types in the actual classroom.From the interviews,it was concluded that teachers were supportive of interdisciplinary teaching in junior high school chemistry,but there were difficulties in implementing it due to the knowledge reserve of other subjects and lack of time.Based on the current state of teaching theory and practice,strategies for teaching interdisciplinary integration in junior high school chemistry are proposed in four aspects: content selection,context creation,curriculum structure,and students’ roles.Based on the strategies,this thesis selects three sections of the junior high school textbook of the Human Education version: water purification,rational use and development of fuels,and important nutrients in human body."In "Water Purification",the theme is water,and the intersection with life,biology,geography,and physics is searched for,and the historical development of water purification is used as a clue to explore the process of water purification.The theme of "Rational Development and Utilization of Fuels" is based on fuels,looking for the intersection with physics and history,exploring the use of automobile fuels in different periods based on the knowledge of heat engines,learning about fossil fuels,and building an interdisciplinary concept;"Important Nutrients in Human Body" is based on nutrients,looking for the intersection with life,labor education,biology,and physics,creating the professional situation of a nutritionist,and exploring and learning about the composition,types,and functions of different nutrients.The course explores the composition,types and effects of different nutrients.Through student interviews,it was found that the interdisciplinary teaching curriculum could achieve the expected goals of stimulating students’ interest in learning chemistry,creating a good classroom atmosphere,helping students better understand the essence of knowledge,improving students’ scientific literacy,and cultivating students’ sense of social responsibility and patriotism.The study found that interdisciplinary integration education is not only more effective in developing students’ core chemistry knowledge and ability to integrate multidisciplinary knowledge to solve problems,but also has greater value in developing the interdisciplinary talent that society needs.
