Research On The Concept Transformation Of "Electromagnetic Induction" In The Physics Of High School Based On Core Concept

Electromagnetic induction is nowadays one of the core concepts of high school physics curriculum.Since the electromagnetic induction concept is quite abstract and scattered,how to apply the concept to teaching and research based on the core concepts of electromagnetic induction,to promote the student to the deep understanding of the concept and electromagnetic induction,to help students construct good cognitive structure and to improve the students' thinking ability has become a focus in the study of this article.The thesis carefully combed the education theory and research results of the concept change based on the theory of constructivism.By analyzing the structure and function of electromagnetic induction and the physical thinking ability of high school students as we ll as high school physics teachers' understanding of the key concepts of physics and electromagnetic induction,the thesis determines the related key concepts of electromagnetic induction is one of the core concept of high school physics,and the important concepts of electromagnetic induction.Then study them in turn.The thesis surveyed high school students in terms of the preconcept of electromagnetic induction to get students' existent preconcept and their misconception and analyze and summarize the underlying causes.At the same time,the two classes that had been taught were investigate to find students' misconception and the causes of the students' learning difficulties.Through the analysis of the survey results,the teaching strategy of the concept transformation of electromagnetic induction is constructed,and the teaching strategy of "electromagnetic induction" is designed.It mainly summarizes three stages.The first stage aims at the analysis of the causes of pre-high school students' pre-concept formation and the analysis of the study,so as to better detect the cognitive structure of the students.The second stage is to stimulate students' cognitive conflict and construct their cognitive structure effectively.The third phase,from taking the co ncept of electromagnetic induction core concepts associated,applied scientific thinking methods and the construction of the physical model from three Angle to construct a scientific system of physical concepts of electromagnetic induction to effectively solve the students' cognitive conflict and realize the change of core concept “electromagnetic induction”.Thus,a teaching strategy for transforming the concept of electromagnetic induction was constructed.According to the strategy of concept change of the research,teaching practice were conducted in the experimental classes focused on teaching design.At last the results of the implementation of the concept change strategy were tested by comparing with the reference class and careful statistical analysis.
