Application Of "Problem Group Teaching Method" In Junior High School Mathematics Review Course From The Perspective Of Large Unit

With the comprehensive popularization of compulsory education,the educational needs have changed.The Revised Mathematics Curriculum Standards for Compulsory Education in 2022 not only strengthens the orientation of curriculum education,requires the establishment of curriculum objectives oriented to core literacy,but also optimizes the structure of curriculum content,requires the design of curriculum content that reflects structural characteristics,that is,emphasizes large unit teaching.The "question group teaching method" is a common teaching method in the middle school mathematics review class,and has achieved good teaching results in the long-term teaching practice.So how can the "problem group teaching method" be effectively applied to large unit teaching to help students form core mathematical literacy?This paper will focus on these issues:How to effectively apply the "question group teaching method" to the large unit teaching,including the implementation procedures,implementation strategies,implementation principles and precautions of the "question group teaching method" in the large unit review course.Whether it is feasible to apply the "question group teaching method" to the large unit review class in junior high school.Compared with the traditional unit review method,whether the application of "question group teaching method" in junior high school mathematics review course from the perspective of large unit can improve students’ performance and help to form a good mathematical core literacy and mathematical thinking ability.For the above questions,the author conducts research through literature analysis,questionnaire survey,interview,case study and experimental research.First of all,through reading the domestic and foreign literature on "problem group teaching method" and "large unit teaching",it will be sorted out and summarized to lay a good foundation for further research.Then put forward the implementation procedure of the "question group teaching method" in the large unit review class: display the knowledge structure chart of the large unit-show the question group prepared before the class-organize students to think independently-exchange and cooperation between teachers and students-summarize and reflect together;The implementation strategy of "question group teaching method" is to set up high-quality question groups,grasp the macro,seize the opportunity,students’ initiative,teachers’ leadership,flexible use of generative resources,repeat and expand,and pay attention to reflection;The implementation principle of the "question group teaching method" is to base on the textbook,consolidate the foundation,appropriately expand,pay attention to the structural integration of knowledge modules,control the difficulty,step by step,spiral up,and compete for the right training based on the learning situation.And try to take the review course of the large unit of function as an example,take the function knowledge system as a large unit,review in an integrated way,explore the teaching design of the large unit of mathematics with the "problem group teaching method" as the review method,help students form the core quality of mathematics,and promote students’ cognitive development.Finally,take the "function" large unit review teaching as an example to carry out the teaching experiment.Through the questionnaire survey,teacher interview,performance analysis and problem solving analysis,the experimental conclusion is obtained:(1)It is feasible and operable to apply the "problem group teaching method" to the large unit review class in junior high school.(2)Compared with the traditional unit review method,the application of "question group teaching method" in junior high school mathematics review course from the perspective of large unit can improve students’ performance and help to form good core mathematical literacy and mathematical thinking ability.
