Research On The Core Concepts Of Physical Mechanics And Teaching Strategies In Junior High School

The core concept of physics is located in the backbone of the discipline,which can organize and integrate the foundation of the knowledge of the discipline.Persistent and in-depth learning of core concepts to achieve a deeper understanding will be beneficial to the learning of related concepts and the establishment of knowledge structure.Therefore,the teaching of core concepts plays an important role in physics teaching.It is found that there is little research on the core concept of middle school physics,especially the core concept of middle school physics.This research mainly determines the core concepts of physics and mechanics in junior high school,such as velocity,force,Newton's first law,pressure,and work,through content analysis,logical thread diagram among concepts,investigation and other methods.On this basis,according to the theory of physics teaching and the teaching practice,this paper puts forward the teaching strategies of four core concepts of physics in junior high school.
