Research On The Design Strategy Of High School Physics Homework Under The Background Of Core Literacy

"Ordinary high school physics curriculum standard"(2017 edition)is proposed to focus on core literacy of the students' physical disciplines and cultivate it.Make the students form their necessary quality and key ability adapting to the individual and social needs of lifelong learning.as one of the important means of teaching,homework is connected to the teachers and students,in and out of class.Current homework cannot meet the needs of improving students' core literacy.Therefore,this paper aims to summarize the homework design strategies suitable for improving students' core literacy through statistics,analysis and thinking.Firstly,this paper is based on the current research on homework design,homework mode and homework evaluation in home and abroad,to help the innovation of later job design strategies.Then with textbook exercises and open sections as an example,through text analysis of surface features and difficulty analysis,found that the homework problems with open column have the features of the following:number of physical exercises after class is moderate,the difficulty is reasonable,open section and the homework problems have the features of rich background,but also there are some exercises have no background,on the background of life accounted for big problems.In addition,questionnaire survey was conducted among students and interviews were conducted with teachers to understand the current situation of physical homework.Based on the analysis of real data,the current homework was found to be too difficult,simple in form and lack of stratification.Then,in view of the problems reflected in the current situation of students'homework,the author puts forward the following Suggestions to improve students'academic core quality:First,to enrich the types of assignments and attach equal importance to written practice;Secondly,physical samples are introduced to provide guidance for thinking.Third,combine the actual situation,pay attention to the original problem;Fourth,integrate frontier knowledge and penetrate the history of physics;Fifth,the hierarchical problem is set based on the knowledge difference.Finally,combining with job design strategy proposed in this paper,the teaching goal and direction of the university entrance exam for a compulsory 1 chapter 4 of the third quarter to operate Newton's second law case design,operation case of difficult homework exercises,set up different levels of homework,joined the rich life,science and technology background,enriched the problem situation,joined the original problem,increase the variety of exercises.Introduce the physics example in the difficult problem part,promote the student's problem solving ability.
