The Research Of Designing Hierarchical Homework And Practical From Perspective Of Key Competencies In Junior Middle School

With the in-depth development of education reform,how to cultivate students’ core quality of subject has gradually become a focus of attention in the current education field.The "double reduction" policy emphasizes on improving the quality of job design,strengthening the research of job design,and enhancing the pertinence and effectiveness of the job.For mathematics discipline,homework,as an important part of mathematics teaching activities to test teaching results,often has the characteristics of abstractness,rigor and application.In the face of the new curriculum changes and the requirements of the "double reduction" policy,in order to promote the development of students’ core qualities,improve the quality of homework design and reduce students’ workload,it is an important direction to carry out research on math homework design.Aiming at the problems existing in junior middle school math homework,this paper conducts hierarchical homework design and practical research based on the new curriculum standard from two dimensions of students’ knowledge mastery and literacy development,providing a feasible idea for front-line teachers to carry out hierarchical homework design of junior middle school math under key competencies.This paper mainly focuses on the following questions:(1)What is the significance of the research on junior middle school math homework design based on key competencies?(2)What are the main problems existing in junior middle school math homework at this stage?(3)According to what stratification standards,how to design junior high school math homework?(4)What is the effect of the practice test of junior high school mathematics stratified homework?This paper conducts a research on key competencies and the design and practice of junior middle school mathematics hierarchical homework.The full text is composed of five chapters:The first chapter describes the research background and significance,the research status and research methods of key competencies,math homework and hierarchical homework at home and abroad.The second chapter summarizes the core concepts and theoretical basis used in the research process,including the concepts of mathematical key competencies,mathematical homework,mathematical homework design,mathematical hierarchical homework,the theory of the nearest development zone,the theory of multiple intelligences,and the theory of objective classification.The third chapter uses the questionnaire survey method to conduct a questionnaire survey on the current situation of junior middle school math homework,and analyzes seven aspects of homework time,quantity,type,difficulty,content,correction and feedback,and stratification of homework.The problems are summarized into five aspects: heavy homework quantity burden,little content richness,uneven difficulty,monotonous type,and difficult stratification.The fourth chapter,according to the design purpose and principle of the work,carries out the hierarchical design of mathematical work from the level of knowledge and ability,introduces the hierarchical basis and hierarchical method,and finally gives the design process of mathematical hierarchical work.The fifth chapter,based on the mathematics hierarchical homework design process of junior high school,carries out the homework case design and analysis of part of the content of Chapter 4,Volume 1,Grade 8 edition of Beijing Normal University Edition.Based on this case,carries out the practical research of hierarchical homework,obtains the feasible practical research results of hierarchical homework design,and finally gives the relevant suggestions of junior high school mathematics homework design.
