Research On Teaching Strategies Based On The Core Concept Of Physics Mechanics In Senior High School

In the actual teaching,it is found that many students' cognition of physical concepts,laws and methods tends to be fragmented,scattered and isolated.The core concept of physics occupies the center of the discipline structure and is the backbone of the discipline knowledge system,including concepts,principles and laws,etc.It has the characteristics of domination,integration and portability.Teaching centering on core concepts can help guide students to build internal relations among knowledge,break the isolated situation among important concepts,and promote students' knowledge integration and development centering on core concepts.There are many concepts of mechanics involved in the curriculum standards and textbooks.This study puts forward "Research on the teaching strategies of the core concepts of physical mechanics in senior high school",and integrates and summarizes the core concepts of the mechanics part,hoping to provide some theoretical basis and strategic reference for the majority of physics teachers in the teaching process of the core concepts.The main contents of this study are as follows:1.Make a comparison between the 2017 version and the 2003 version of the course standard in terms of course structure,teaching content and teaching Suggestions,and define the direction of the course reform.2.Compared the changes in content structure,column setting,exercise writing and other aspects of the new and old textbooks of PEP edition,interviewed front-line teachers,analyzed and determined the core concepts of each theme module of the new textbooks of PEP Edition.3.A questionnaire survey was conducted among 31 physics teachers in Jilin Provincial Experimental Middle School.Newton's second law,kinetic energy theorem,conservation of mechanical energy,Acceleration and uniform variable linear motion are the most important core concepts in high school physics and mechanics.4.Analyze the distribution of physical mechanics test sites in the national College entrance Examination of the past three years,and verify the results of teacher questionnaire.5.Put forward the teaching strategy of the core concept of physics and mechanics in senior high school,including the following three points:(1)Organize teaching with core concepts as the focus;(2)Situational creation as the carrier and problem-driven as the approach;(3)To improve the key ability,the achievement of discipline accomplishment as the foothold.
