Research On The Determination Of Core Concepts And Teaching Strategies Of High School Physics

High school physics,as an important subject in the high school science education,can help students understand the world and cultivate their science thinking.In recent years,China's science education has paid more and more attention to the core concepts.In the "Ordinary High School Physics Curriculum Standards" promulgated in 2017,it is clearly proposed to cultivate students' physical core literacy,focusing on process evaluation to promote the development of core literacy.The cultivation of core literacy is inseparable from the core concept learning.Clarifying the core concept of high school physics and carrying out effective teaching activities around it is the most basic requirement,the most core method and the most effective way to help students improve the literacy of physics.Based on the above background,the purpose of this paper is trying to explore the core concepts and its brief descriptions of high school physics in the textbooks by text combing and questionnaires.Through some methods such as literature analysis and teaching case analysis,some effective strategies for corresponding teaching around core concepts are briefly described.The conclusions of this study are:(1)Through the lengthy combing of high school physics textbooks and the questionnaires and summary results issued to front-line teachers,the author summarizes ten core concepts from high school physics.They are "force and movement","work and energy","electrostatic field and magnetic field","changeable electromagnetic field","molecular dynamics theory","thermodynamic law","fluctucation and its property","conservation of momentum","atomic structure and nucleus",and "wave-particle duality and relativity".(2)In view of some difficulties existed in daily teaching,based on the existing literature and front-line teaching practice,an effective strategy for carrying out corresponding teaching around the core concept is proposed:first,attach importance to the teaching of core concepts and enhance the awareness of core concept teaching;second,organize the teaching links around the core concepts and step efforts to strengthen the core concept teaching.Third,carry out effective teaching at the center of core concepts and realize the daily teaching.
