Investigation And Research On The Concept Of Pre-magnetic Field In High School Physics

Students do not enter the classroom with a blank brain,but with their own experience in learning and life after learning,that is,pre-concept.Therefore,before teachers teach students,it is necessary to have a thorough understanding of what pre-concepts students have about the content they are going to learn,which is conducive to teachers’better teaching and students’ learning.The magnetic field is an important part of physics learning in high school.Students have many preconceptions that interfere with learning before they study.Therefore,the study of the preconceptions of magnetic field is helpful to teaching.Firstly,the paper consulted the literature at home and abroad,sorted out the literature,summarized the current situation of the research,and analyzed the related theory of the preconception;on the basis of the analysis of the textbooks of senior high school,interviewed the excellent front-line teachers,and understood the problems that students had in the process of learning the magnetic field.Finally,based on the questionnaire CSEM from abroad,a questionnaire about the preconception of physical magnetic field in senior high school is compiled.This paper investigates the pre-concept of magnetic field in senior high school physics by using the questionnaire of pre-concept of magnetic field in senior high school physics.The survey found that students:1.There are some wrong preconceptions in the understanding of the concept of "field" in magnetic field.2.There are erroneous preconceptions in the understanding of knowledge superimposed by ampere force,Lorentz force and magnetic field.3.There are wrong preconceptions in the knowledge understanding of "magnetic induction line"Some students were interviewed,and the reasons for the erroneous preconceptions formed by the students before learning the knowledge of magnetic field were summarized as follows:the influence of life concept;the solidification of thinking mode;the establishment of inappropriate physical model;the lack of curiosity and the neglect of the preconceptions in the mind.According to the results of the study,three teaching suggestions are put forward.1.Pay attention to the preconception of students’existence and explore actively.2.Contrast the new concept with the former one and establish the connection.3.Pay attention to linking with reality and form a knowledge system...
