Teaching Design And Practice Of Review Course In Senior High School Based On Physical Model

The Curriculum Standards of General High School Physics(2017 Edition)integrates the construction of physical model into the cultivation of students' core literacy,and the high school teaching research based on physical model construction is also increasing.This series of changes requires teachers to pay attention to cultivating senior high school students' physical model construction ability in class.For students,learning to build physical models is the basis of scientific thinking.The construction of a complex physical model often involves a lot of knowledge and requires students to have a strong comprehensive ability.This is the reason why most students still do not solve the problems or make mistakes after the new class.In the review class,through the construction of physical model,students can integrate the whole physical knowledge system,with the method of physical model construction,improve students' ability to solve problems,so as to meet the requirements of core literacy.This paper first understands the background and research significance of physical model construction in high school review class teaching by checking the relevant literature of "physical model construction" at home and abroad.Then it defines the relevant concepts,and analyzes the psychological and pedagogical ideas supporting the construction of physical model.Then,through the methods of questionnaire and interview,this paper investigates the students' ability of physical model construction and the current teaching situation of teachers based on physical model construction.The results show that although physical model construction has initially appeared in the front-line teaching,it does not reach the depth required in the new curriculum standard in the review class.In order to solve the problems found in this paper,I select two typical physical models for relevant teaching design,namely "spring model" and "conveyor belt model".And I practice them in the review class of the internship class.In practice,I guide students to experience the process of physical model construction,so as to achieve better teaching effect.In order to get the practical effect of this study,I compare the students' scores before and after the teaching of physical model construction in the review class.Through the improvement of the scores,it reflects that the construction of physical model does help most students form a huge physical knowledge system in the review class,help students solve the problems encountered in real life and lay a foundation for lifelong development.
