Hierarchical Construction And Teaching Strategies Of Physics Ideas In Senior High School Under The New Curriculum Standard

The "General High School Physics Curriculum Standard(2017 Edition)"(The following abbreviated to the "New Curriculum Standard")proposes that the core literacy of the discipline is a concentrated expression of the value of discipline education,and physics ideas occupy the first place among the core literacy of the four disciplines.Therefore,how to construct high school students’ physics ideas in physics teaching has become an important topic in current teaching research.It is against this background that this research conducts an in-depth analysis of physics ideas under the New Curriculum Standard,focusing on the question "How are physics ideas formed and how to promote the teaching of physics ideas?" The specific research contents are as following:First,a hierarchical model is constructed with physical concepts and physical laws as carriers,and then form sub-ideas with a lower degree of integration,and finally form physics ideas.The connotation and level of physics ideas are cleared through reading New Curriculum Standards carefully.Combining the formation process of ideas,a hierarchical model of physics ideas is constructed on the basis of the existing teaching model initially.Then starting from the content of the course,the conceptual physics concepts and laws are refined through sorting out the teaching requirements of courses involving physics ideas in the New Curriculum Standard Furthermore,the sub-ideas of the ideas of matter,movement and interaction,and energy are further divided,which finally completes the hierarchical model of the physics ideas.Second,teaching strategies are put forward on the construction of physics ideas.Questionnaire surveys are carried out on the teaching and learning of the current physics ideas construction in order to avoid the suggestion of teaching strategies being too subjective.Combining the current status quo and the requirements of the New Curriculum Standard for the teaching of physics ideas,the corresponding teaching strategies are designed from the three levels of the physics ideas hierarchy model.At the level of physics concepts and laws,five teaching strategies including idea-based and leading knowledge teaching are put forward;At the sub-ideas level,three teaching strategies including integrating into the history of physics and perceiving the evolution of concepts are proposed;At the idea level,two teaching strategies are proposed,including reviewing topics and integrating physics ideas,and a total of 10 teaching strategies are proposed.In the process of discussing teaching strategies,specific examples are used to explain in order to promote the further development of high school students’ physics ideas from lowlevel to high-level.Third,a teaching model based on idea construction is designed and case analysis are conducted.This research designs a teaching model by combining the teaching process and corresponding teaching strategies,and takes "Newton’s First Law" and "Electric Potential Energy and Electric Potential" as examples to illustrate the process of teaching design mode,in order to provide some reference suggestions for the teaching of high school physics ideas’ construction.
