Research On The Teaching Of Classical Exercises Of Electromagnetic Induction Based On Core Literacy

The core accomplishment of physics discipline mainly includes four aspects: "physical concept","scientific thinking","scientific inquiry","scientific attitude and responsibility".The 2017 edition of Common High School Physics Curriculum Standards clearly points out that high school physics curriculum should further promote the cultivation and development of students' core literacy of physics on the basis of compulsory education.In the implementation of teaching practice,how to penetrate physical science core literacy into teaching,to integrate the knowledge,skills,attitudes and values,to help students set up the correct values,trains the student to adapt to the social development need the essential character and key ability,it is worth every physics teacher research topic.In the classroom,the selection of classic textbook exercises for teaching is not only an indispensable link,but also an important way to cultivate students' core quality of physics discipline.It plays an important role in helping students consolidate the knowledge they have learned,and cultivating students' problem-solving ability,logical thinking ability and communication ability.However,there are few studies on some classical exercises in physics textbooks at present.Therefore,based on physical discipline core literacy teaching goals,choose high school physics "electromagnetic induction" section of a classical problem as the breakthrough point,take the literature research,questionnaire investigation,case analysis and other methods,in optimization of the constructivism theory,teaching theory and bruner's cognitive theory as the theoretical basis,to carry out the following several aspects of the research is necessary.First,through the introduction of the research background and research status of the review,to determine the research content and research methods,the significance of the study and the reason for the selection of classic exercises.Second,it defines the relevant concepts and expounds the theoretical basis of the research.Thirdly,on the basis of the analysis of the content of the "electromagnetic induction" chapter,the content of the classic exercise "Lenzi Double Ring" in different versions of the textbook is analyzed and compared,which sets up a knowledge framework for the research of this topic.Fourthly,the classical exercises based on the Lenz Double Ring experiment are explored and developed.Through inquiry,the impact of "lenz 2-ring experiment" closed loop and open aluminium ring move the nature of reason is that the strength of the magnet magnetic,and magnet near or far away from the way,the size of the aluminum ring diameter,the width of plates,the thickness of aluminium,aluminium ring opening size,factors such as the distance between the two aluminum ring has nothing to do,and based on "lenz 2-ring" experiment is improved and innovative development.Fifthly,based on the experimental exploration of "Lenz Double Ring",the chapter of "Electromagnetic Induction" is taken as an example to summarize the teaching strategies of high school physics exercises.Sixth,carry out the discussion on the teaching design based on the "Lenz Double Ring" experimental activities,so as to provide some reference for the teaching of front-line teachers.Seventh,summarize the research on this topic,reflect on the existing deficiencies and improvement measures.
