Design And Teaching Research Of Junior High School Chemistry Interdisciplinary Practice

Entering the new era of economic globalization,with the rapid development of science and technology and increasingly intense competition among various countries,the requirement for our country to train talents in innovative science and technology is constantly increased.According to the Chemistry Curriculum Standards for Full-time Compulsory Education(2022edition),at least 10% of class hours should be devoted to interdisciplinary subject learning.Interdisciplinary practice activities can strengthen the connection between chemistry and other disciplines,and this teaching method of practical education can improve the core quality of students.Therefore,the implementation of interdisciplinary themed activity teaching in junior middle school is of practical significance to meet the needs of the country’s comprehensive innovative talent training.The main work and results of this research are as follows:In the theoretical research part,literature research method is used to analyze the relevant researches on interdisciplinary teaching and comprehensive practice activities at home and abroad,to clarify the concepts of interdisciplinary and chemical interdisciplinary practice activities,and to discriminate the related concepts of activity curriculum,comprehensive curriculum,interdisciplinary practice activity and comprehensive practice activity curriculum.Through the analysis of the interdisciplinary practice activities in chemistry,the origin,characteristics,types and teaching value are clarified.With the support of relevant theories,the design principles and design process of interdisciplinary practice activities in chemistry are proposed,and the schemes such as the selection of activity theme,the formulation of activity objectives,the design of dominant tasks and sub-tasks,the determination of activity results,and the design of the whole process evaluation are discussed.Summarize the general process of chemistry interdisciplinary activity design.In the practical research part,according to the design process of interdisciplinary practice activities of chemistry proposed in the theory part,the teaching case of "Water quality testing and self-made water purifier" of interdisciplinary practice activities of chemistry was designed and practiced in junior chemistry class.The teaching effect of interdisciplinary practice activities in chemistry was tested by classroom rating scale and semi-structured interview.The results show that the process of chemistry interdisciplinary practice activities designed by this research has a guiding effect on the study of chemistry interdisciplinary practice activities in junior middle school,which is conducive to improving students’ cooperative exploration ability and problem-solving ability,and plays a positive role in the study of chemistry.
