Research On Design And Practice Of Junior High School Physics Hierarchical Homework

Homework is a link between teachers and students and a part of teaching activities.In terms of function,homework can not only help students better grasp and consolidate physics knowledge in class,improve physics learning ability and exercise physics thinking.It can also help teachers check the teaching effect and adjust the teaching strategies and methods in time.However,in the actual teaching process,the phenomenon of "emphasizing teaching" and "undervaluing homework" often exists.The form of homework objectives is single,the difficulty of homework content is not screened,and the individual differences of students are ignored.Therefore,this study carries out the research on physical hierarchical homework according to the individual differences of students.This paper combs and summarizes the current status of physics stratified homework at home and abroad through literature research,finds the effective theoretical basis for the stratified design of physics homework,and defines the concept of physics stratified homework,which is a form of homework adopted in teaching practice in order to achieve the balanced development of students and improve the learning of different students’ physics courses at different levels.In order to ensure the effectiveness and pertinentiousness of this study,questionnaire survey was conducted from the two aspects of first-line junior middle school physics teachers and students to understand the status quo of junior middle school physics homework as well as teachers’ and students’ attitudes and views on layered physics homework.Then four problems existed in junior middle school physics homework were found according to the survey results.That is,the quantity of work needs to be adjusted,the difficulty of work content lacks hierarchy,the type of work is monotonous,and the method of job evaluation is mechanical.Based on humanistic learning theory,multiple intelligences theory,the theory of proximal development area and the theory of individualized teaching,based on the problems existing in the current junior high school physics homework,this paper puts forward five strategies for the hierarchical homework design of junior high school physics from the theoretical level.That is,to clarify the assignment direction according to the curriculum standards,set the assignment objectives according to the teaching objectives,set the assignment difficulty according to the assignment difficulty model,enrich the assignment types,design diversified assignments,and establish and improve the assignment evaluation system.Through the teaching practice of stratified homework,the strategy of physics stratified homework design in junior high school is applied,and the practical effect of physics stratified homework in junior high school is tested through questionnaires,students’ scores before and after testing,case studies and other aspects.The research results show that:(1)the implementation of physics stratified homework can effectively improve students’ interest in physics learning.(2)The implementation of layered physical homework can improve students’ enthusiasm and initiative in completing homework and enhance the effectiveness of homework.(3)The implementation of layered physics homework can improve students’ physics scores and promote the cultivation of students’ physics core literacy.
