| At present,China’s education reform is at a critical stage,at the 19th meeting of the Central Committee for Comprehensively Deepening Reform on May 21st 2021,it was pointed out that"One of the most prominent problems of the compulsory education is that the burden of primary and secondary school students is too heavy and the problems of short-sightedness and utilitarianism have not been fundamentally solved".Under the background of the current"double reduction"policy,changing the status quo that junior high school students’mathematics after-school homework is mainly characterized by exercise training,and integrating mathematical practice homework into after-school homework,which will be of great value for junior high school students to reduce the mathematics learning burden,increase efficiency,cultivate mathematical literacy and increase interest in mathematics.Through the literature research on the practical homework of mathematics in junior high school,this paper defines the practical homework of mathematics in junior high school as a form of mathematics homework that is designed according to students’knowledge and experience,with the goal of improving mathematical literacy,cultivating practical ability and developing mathematical emotions.The paper also summarizes the current domestic and foreign research status of junior high school mathematics practical homework and draws the theoretical basis of this paper.In order to understand the current status of the implementation of junior high school mathematics practical homework,this paper has developed a questionnaire and interview outline for junior high school teachers and students,from the results of the investigation,we find that there are some problems in the process of implementing the practical work of mathematics in junior middle school.In the aspect of students,one is the lack of practical homework experience,the other is the bad habit of practical homework,and the third is the lack of practical consciousness,fourth,the lack of reflection on practical homework;On the part of teachers,first,the source of practical work is single,second,the difficulty of practical work lacks hierarchy,third,the problem of practical work lacks openness,fourth,the goal of practical work lacks effective design,the fifth is the lack of scientific evaluation of practical work,the sixth is the lack of practical work feedback attention.The research found that(1)the test-taking atmosphere is strong,the proportion of written assignments is too large,(2)the type of mathematical practice assignments is single,(3)the mathematical practice assignments lack connection with real life,(4)the mathematical practice assignments lack overall design,(5)There is no established standard for the evaluation of mathematics practical homework,and(6)the lack of attention to the feedback of mathematics practical homework is the main reason for the problems of the current mathematics practical homework in junior high school.Therefore,this paper puts forward some suggestions to solve the problems existing in the current junior high school mathematics practical homework,one is to enrich the number and types of junior high school mathematics practical homework;The other is to widen the source of junior high school mathematics practical homework,and to keep in close contact with life;The third is to optimize the design of junior high school mathematics practical homework;The fourth is to value the evaluation of junior high school mathematics practical homework,to improve the quality of learning;The fifth is to value the feedback of junior high school mathematics practical homework,to achieve the reduction of burden and increase efficiency;The sixth is to establish a supporting system for practical homework in junior high school mathematics.Based on the above research,in order to verify the practicability,operability and effectiveness of these suggestions,provide a basis for the research of this paper and also provide a reference for first-line junior high school mathematics teachers,the author carried out educational experiments in internship school,the experiment results show that mathematical practical homework is conducive to improving the mathematics performance of junior high school students,helping to cultivate junior high school students’mathematical literacy,improving students’awareness of cooperation and practice,cultivating mathematics interest,and making students feel the close connection between mathematics and life. |
