Study On Teaching Strategies Of The Core Concept Of Mechanics In Senior High School

In recent years,the education circle has paid more and more attention to the teaching of core concepts.With the international community's attention to the teaching of core concepts,it has become a trend to organize classroom teaching centering on core concepts.Core concepts include a wide range of physical knowledge,which are concepts,principles or laws that are central to the structure of each discipline.Students' mastery of core concepts has a direct impact on their understanding of subject knowledge.Therefore,it is of vital importance for students to learn core concepts well.High school physics is one of the important courses of science education.Mechanics is the foundation of high school physics and the foundation of learning electromagnetics.Therefore,investigating the specific content of the core concepts of mechanics,analyzing the difficulties of students' learning,and proposing the teaching strategies of the core concepts of mechanics play an important role in both teachers' teaching and students' learning.Through the analysis of the high school physics curriculum standard,the high school physics teaching material,mechanics of high school physics teaching material,the core content of core concept,summed up the mechanics will be distributed to a line of these concepts into the questionnaire teachers,teachers through their own understanding of the importance of the concept of scale,it is concluded that high school physics mechanics of important core concept.In order to understand high school students' mastery of the core concepts of mechanics,FCI(Force Concept Inventory)questionnaire will be issued to students to evaluate the students,calculate the correct rate of each type of questions,and summarize the students' mastery of concepts.According to the survey results of front-line teachers and the analysis of students' mastery of core concepts,this paper puts forward the teaching strategies of core concepts,so as to play a guiding role in the teaching of front-line teachers.In the combing of textbooks and the investigation of front-line teachers,it is concluded that Newton's second law,the law of conservation of mechanical energy,the decomposition of force,the flat throw motion and the synthesis of force are the core concepts of mechanics.Based on the investigation of students,it is concluded that students' understanding of the core concepts is superficial,and they fail to truly understand the connotation and extension of the concepts,and they lack a deep understanding of the specific content of the concepts.According to the above survey results,core concept-centered teaching strategies are proposed,including four points: first,Strengthen teachers' teaching concept centering on core concepts and promote the teaching of core concepts;second,Introduce life situation into core concept teaching to stimulate students' interest in learning core concepts;third,Organize teaching around core concepts to help students understand core concepts;fourth,Change the evaluation method and promote students' mastery of the core concepts.
