Exploration Of Efficient Cooperative Learning Model Of Junior Middle School Mathematics Based On Dynamic Groupin

The promulgation of the "Mathematics Curriculum Standards for Compulsory Education(2022 Edition)" signifies a necessary and crucial step in the reform of mathematics curriculum in compulsory education in China.In the current educational practice,the real educational value of group cooperative learning has not been brought into play due to the influence of various factors.This paper summarizes the key articles related to cooperative learning and dynamic grouping,makes a systematic analysis of the existing research results to obtain research ideas and methods,and defines the concepts of cooperative learning and dynamic grouping.This paper summarizes the research status of cooperative learning and dynamic grouping at home and abroad,and expounds the theoretical basis of cooperative learning and dynamic grouping.Through the design of students’ questionnaires and teacher interview questions,this paper investigates the present situation of the application of group cooperative learning in the current educational practice,and designs the teaching control experiment scheme in the later stage and puts it into practice based on the present situation of the problem.In the later stage of the experiment,the test model of students’ core literacy level was designed,the test paper was compiled,and the experimental data were analyzed descriptively.The preliminary conclusions are as follows:There is a positive correlation between students’ mathematics achievement and students’ cooperative learning level;There is no significant difference between students’ gender and cooperative learning level;Most students are not familiar with the concept of dynamic grouping.Generally speaking,in the traditional static group cooperative learning process,students’ inquiry and understanding ability,representation and systematization ability,planning and execution ability,monitoring and reflection ability have not been fully developed.By comparison,it can be found that cooperative learning can be used as a favorable carrier to improve students’ mathematical literacy,and dynamic grouping is an effective catalyst to achieve the formation of students’ core literacy.Group cooperative learning based on dynamic grouping is very effective in the transformation of students with learning difficulties,the cultivation of the backbone and the excellence of top students,and plays a significant role in improving students’ comprehensive mathematical literacy.This shows that it is reasonable and necessary to change the traditional static grouping mechanism and apply the group cooperative learning mode under the dynamic grouping mechanism.
