Research On The Design Of Junior High School Mathematics Homework Under The "Double Reduction" Policy

The heavy academic burden of students has always been an important concern of the country,and homework burden is one of the main sources of academic burden.Since the establishment of New China,China has introduced a series of policies to reduce the learning burden of students.The "double reduction" policy issued in 2021 is a major decision made by the Party Central Committee to promote the great rejuvenation of the Chinese nation,which puts higher requirements on students’ homework.The purpose is to improve the quality of homework design,reduce the burden of students’ homework,and promote the healthy and comprehensive development of students.Therefore,this study takes secondary school quadratic functions as an example to explore homework design in the context of "double subtraction".The following issues will be addressed during the research process:(1)What is the current situation of homework design for junior high school mathematics in the context of double subtraction?(2)How to construct the design framework of math homework and design math homework cases?(3)How about the effect of homework design after math class?This study first analyzed and sorted out relevant literature through the literature research method to clarify the current development status of homework research.On this basis,a teacher’s questionnaire is designed from two dimensions: homework concept and homework design,and a student’s questionnaire is designed from two dimensions: homework assignment and homework effect.Using questionnaire surveys and teacher interviews,the current status of math homework design for grade9 in junior high school is obtained.The main performance is as follows: teachers narrowly believe that homework after class is to consolidate knowledge and is the continuation of the classroom;In the process of designing homework,there is a weak awareness of thinking about homework goals;The job type is single,and most of them are basic types of jobs;The lack of hierarchical design in job design is still a one-size-fits-all approach;The subject and means of operation evaluation are single.Then,based on the current situation of homework design,in the context of "double subtraction",this study proposes to strictly follow the principles of scientificity,diversity,purposefulness,diversity,and development to design and implement after-school homework using quadratic functions as an example.While designing homework,this study constructs a framework for homework design from three aspects: homework objectives,homework content,and homework evaluation,and designs specific homework cases based on this framework.Finally,in order to verify the effectiveness of the homework designed by the framework,evaluation criteria are designed from both macro and micro dimensions to evaluate the after-school homework design.The recognition of the design framework through teacher evaluation can help teachers design reasonable homework after class and reduce the workload of students.
