Research On The Physical Core Concepts Of Magnetic Field And The Learning Progression In Senior High School

The study of senior high school physics courses is a process of conceptualizing the explanation of scientific facts.Obtaining the core concepts that integrate the discipline of physics can lay a foundation for students' lifelong development.In essence,learning progression is a thought process that gradually deepens the understanding of core concepts and tends to be complex.It is a concrete manifestation of the conceptualization process of scientific fact explanation.Therefore,building the learning progression of core concepts can help students form a good knowledge structure and deeply understand scientific concepts.The complex and abstract physical concepts of magnetic field in senior high school require high thinking ability of students,which makes it difficult for some teachers and students to teach and learn.Therefore,this study will build the learning progression of the physical core concepts of magnetic field in senior high school,and expect to help the physical concept teaching of magnetic field in senior high school.This thesis consists of the following three parts:Part one: sorting out the elementary and senior high school physics curriculum standards and textbooks of People's Education Press,sorting out the basic concepts of magnetic field,and drawing concept maps,and interviewing front-line teachers,and searching out the physical core concepts of magnetic field in senior high school.Part two: constructing the learning progression's hypothesis of the physical core concepts of magnetic field in senior high school.Based on the physical core concepts,determining the learning progression's dimensions;according to the elementary and senior high school physics curriculum standards,textbook of People's Education Press,SOLO classification theory and the development of students' reasoning mode,dividing the learning progression's level;preliminarily constructing the learning progression's hypothesis of the physical core concepts of magnetic field in senior high school.Part three: testing the learning progression's hypothesis of the physical core concepts of magnetic field in senior high school.According to the hypothesis,developing the test paper named The Physical Learning Test Paper of Magnetic Field in Senior high school.This test paper was developed to explore students' mastery of the concept of magnetic field,and the learning progression's hypothesis was revised according to the test results.This thesis mainly got the following conclusions:The physical core concepts of magnetic field in senior high school are magnetic induction line,magnetic induction,ampere force and lorentz force.The physical core concepts of magnetic field in senior high school could correctly reflect students' thinking development path.
