The Practice Of Integrating The History Of Physics Into The Teaching Of "Electrical And Magnetic" Unit In Junior High School

Both the old and new editions of the "Compulsory Education Physics Curriculum Standards" emphasize the cultivation of students' scientific inquiry ability.The process of teachers guiding students to explore physical phenomena is actually the process of cultivating students' scientific inquiry ability.Under the "double reduction" policy,parents have put forward higher requirements for the teaching quality of schools,so it is urgent to change the teaching design of physics classrooms in a specific and targeted way.One of the aims of education in the history of physics is to cultivate students' scientific inquiry ability and scientific spirit.Therefore,taking the ninth grade physics "Electrical and Magnetic" unit of the People's Education Edition as the research object,carrying out the design of integrating the relevant history of physics into unit teaching,in order to inject new vitality into the quality and efficiency of junior high school physics classroom teaching.In the unit "Electrical and Magnetic",the process of human exploration of electrical and magnetic phenomena is selected as the main line of unit teaching design.Taking the history of physics as the main carrier,we will carry out practical research on unit teaching design to fully present the humanistic education function of the history of physics.There are six chapters in this paper,which are divided into two parts:theory and practice.In the theoretical part,the literature research method is used.First,collect the research status of "physics history" and "unit teaching design" by domestic and foreign scholars,and clarify the research background,purpose and significance of this paper.Then,define the concepts of "physics history" and "unit instructional design" to provide theoretical support for research from the aspects of pedagogy and psychology.Finally,according to the unit teaching design steps,devise a case of "Electrical and Magnetic" unit teaching design.In the practical part,a questionnaire survey method is used.Based on the investigation of the application of the history of physics and unit design in the actual teaching of the junior teachers and students of four middle schools in Yingkou area,it provides a practical basis for the integration of the history of physics into the unit teaching of "Electrical and Magnetic".According to the experimental method,teaching practice is carried out in two classes.The experimental class is taught in accordance with the teaching design case of the "Electrical and Magnetic" unit,and the control class is taught in the traditional teaching mode.After the teaching activities,the practical effect of integrating the history of physics into the teaching design of "Electrical and Magnetic" is analyzed from three aspects: students' classroom performance,unit test results and interviews with students.The practical results show that taking the history of physics as the main body,the unit teaching in "Electrical and Magnetic" can improve students' scientific inquiry ability.Designing unit teaching content based on the historical development process of electrical and magnetic can promote the development of students' scientific thinking.Help students build the knowledge structure of this unit,and solve the problem of mixed content and difficult memory.In the process of exploration,students dare to criticize and question physical phenomena,make bold guesses and assumptions,and have the courage to explore,and improve their cognitive level in the process of personally operating experiments.Finally,summarize and reflect,aiming to provide reference for the teaching of first-line junior high school physics teachers,and let the idea of integrating the history of physics and unit teaching design play a greater role in the physics classroom of junior high school.
