Research On The Status Quo And Transformation Strategy Of Pre-concept Of Physics In Junior High School Based On The Connection Between Primary And Junior High School

Pre-concept is very important for the study of physics in junior high school.Students have already had certain knowledge base in their mind before they get into physics formally,and these existing knowledge may promote or hinder subsequent learning to some extent.We call such knowledge base pre-concept.This paper mainly studies the transformation strategy of pre-concept in junior high school physics.Firstly,by referring to literature,it makes a comparative study of the similarities and differences between the curriculum standards and textbooks of primary school science and junior high school physics,compares different expressions of the same knowledge point,and tries to find out the false pre-concept easily produced in primary school science textbooks.Then,through communicating with front-line physics teachers and taking into account the actual learning situation,a questionnaire was prepared to investigate the status quo and transformation of students’ pre-mechanics concepts.The survey results show that the first grade students generally have the typical mechanics preconcept,the second grade students have some changes in the preconcept but the wrong preconcept is still persistent.Finally,I put forward teaching transformation strategies based on cognitive conflict,situational creation,constructivism and group cooperation.It is expected to improve the efficiency of physics classroom teaching in junior high school.Then the transformation strategy is applied to practical teaching cases,combining theory with practice.
