Research On The Problem Chains Design Strategy Based On The Core Literacy Of Physics

Cultivating and developing the core literacy of students in physics is not only a requirement of the times,but also a particularly important part of physics teaching in senior high school.However,there are still the following problems in the current physics classroom teaching in senior high school: teachers determine the way of teaching and presentation of knowledge according to their many years of teaching experience,and students passively accept it.In the classroom,too much emphasis on teachers and knowledge as the main body,and the development of students' ability is ignored.In order to meet the new requirements of the new curriculum standards for physics teaching in senior high school,we tried to find a possible way to cultivate and develop the core literacy of physics for senior high school students.At the same time,it also provides more teaching strategies which cultivate and develop the core literacy of high school students in physics for the frontline teachers.In view of this,this paper focuses on the problem chain design strategy based on the core literacy of physics.By studying and combing the relevant literature,this contents finds out the problems existing in the current physics classroom teaching in senior high school,as well as the new requirements for physics teaching put forward by the core literacy of physics.This paper puts forward the possible ways to cultivate and develop the core literacy of physics for senior high school students from the perspectives of epistemology and classroom teaching.This study summarizes the advantages of using problem chains to cultivate and develop physics core literacy of senior high school students,and gives the design principles of problem chain based on physics core literacy: Thinking-driven,the foothold of problem chain design,inspiration,the key point of problem chain design,simple and inefficient,avoidance of problem chain design.In different stages of physics classroom teaching,different strategies for designing problem chain are summarized:problem-situation as the strategy in the physics classroom situation creation stage,inquiry-construction as the strategy in the analysis and solution stage of physical problems,induction-summary as the strategy in the induction and summary stage of physics concepts and laws,and promotion-application as the strategy in the understanding and consolidation stage of physical knowledge.We presented the teaching examples of "exploring the production conditions of induced current","Lenz Law" and "Faraday Law of Electro-Magnetic Induction" in the fourth chapter of Senior High School Physics elective 3-2(people's Education Publishing House).After the end of teaching,the scores of the experimental group and the control group were collected and analyzed,and the data were analyzed and evaluated by SPSS 20.0.through the comparison,it is found that the strategy of problem chain design can really promote the cultivation and development of senior school students' core literacy of physics.On the basis of this study,we given the teaching path and suggestions for the problem chain teaching based on the core literacy of physics,enriches the teaching strategies of front-line teachers,and conduct useful discussions for the better training and development of the core literacy of high school students.
