Research On Assignment Design Of High School Mathematics Unit Under The Background Of "Double Reduction"

In July 2021,the General Office of the Central Committee of the Communist Party of China and the General Office of the State Council issued the "Opinions On Further Reducing The Homework Burden And Off Campus Training Burden Of Students In Compulsory Education",making "reducing burden and improving quality" a core issue in homework design under the background of "Double Reduction".The overall design concept of unit assignments provides an effective path for balancing the workload and quality of assignments.How to reflect high-quality homework design in unit homework design and how to prepare unit homework are important issues that should be considered in unit homework research.Based on this,this study identified the following research questions:(1)What are the constituent elements of high school mathematics unit assignments in the context of "Double Reduction" ?(2)What are the principles and processes for designing high school mathematics unit assignments?(3)How effective is the practice of high school mathematics unit assignments based on the overall design concept?Therefore,based on literature analysis and interview research,this study constructs a unit assignment design framework,design principles,and design process under the background of "Double Reduction".At the same time,data was collected through questionnaire surveys and interviews to analyze the teacher’s homework design situation,their attitude towards unit homework design,influencing factors of homework design,and guidance on homework framework.The results showed that the teacher agreed with the overall design concept of unit homework.On this basis,with "Basic Elementary Function" as the content,the case study of high school mathematics unit homework based on the overall design idea is carried out.Finally,through questionnaire surveys and interviews,the effectiveness of implementing unit assignments based on the overall design concept was analyzed,The following conclusion is drawn:(1)Unit assignments help cultivate students’ interest in mathematics learning;(2)Unit assignments can effectively reduce students’ homework burden;(3)The implementation of layered homework and effective coordination with unit assignments can jointly promote students’ development.
