A Study On The Relationship Between “Electricity And Magnetic” On The Basis Of Learning Progression

When students study the relationship between electricity and magnetism in high school,many students think that part of the content is too difficult and the content span is too long.This study is based on the advanced theory of learning,aimed at closely linking the junior-senior high school "electricity and magnetic" relationship and narrowing the content span to help students successfully completed the transition of knowledge from junior high school to senior high school.Finally effectively solve the learning difficulty caused by the lack of convergence from the transition of "electricity and magnetic" knowledge from junior high school to senior high school.This study consists of three parts:Study one: The study is a comparative analysis of the teaching content of the relationship between electricity and magnetism in the junior and senior high school.Compared with the concept of "electricity and magnetism" in the junior-senior high school and the standard of course content,we can find out the span of knowledge accurately,and provide the basis for the determination of advanced level and end point.Study two: Constructing the learning progressions of the relationship between“electricity and magnetism”in junior and senior high schools.The first part:analyzing research results about electromagnetic concept of junior high school and interviewing with junior high school physics teachers,we can know the performance of the third grade students to provide theoretical support for the determination of the starting point;The second part:analyzing of the research results of the electromagnetic concept in high school,which can provide reference for the establishment of the concept test volume.On this basis,combining with the SOLO theory,we establish 6 important concepts test in the relationship between “electricity and magnetism”,and test and analyze the senior high school students.The results detect the levels of students' understanding of the 6 concepts and misconceptions.All of these work is aimed at providing the basis for dividing detail “order” of the level.The third part: Adopting the longitudinal research method,we focus on the twoadvanced latitudes of electromagnetism and magnetism and electricity,and construct the advanced theory of "electricity and magnetism",which aims at providing a theoretical framework for the teaching design of the connection between "electricity and magnetism".Study Three:A Study on the Teaching Plan of "electricity and magnetic" relationship based on advanced learning.Taking the induction current as an example,this paper designs a feasible teaching method by using the teaching strategy of concept change or concept reorganization,which could help students solve the cognitive conflict,and establish a correct understanding of the concept of induced current,and achieve the teaching objectives.The main conclusions of this study :First,the students learn electromagnetic content in the junior high school,which can help students to deeply understand the relationship between “electricity and magnetism”;Second,using the method of longitudinal study to build learning progressions of the relationship between “electricity and magnetism” in junior-senior high school,we will describe the development path of the students' thinking in detail,and find out closest connection of the junior and senior high school about the relationship between“electricity and magnetism”;Third,analyzing the description of learning progressions about the relationship between “electricity and magnetism”,which can clear the concept of student's myth and the obstacles of the "order",and can help teachers select the concept of teaching strategies and design teaching activities meeting the students' cognitive development.The ultimate goal is to achieve the layers of teaching content progressive and close.
