The formation of cooperative learning groups is an effective basis for cooperative learning. In primary school Chinese classroom teaching, I consciously group students of different levels from the teaching content and students' reality. Under normal circumstances, the front and back tables are grouped by four people, and four people work next to each other, which makes it easier to change the requirements for space and space. Organize democratic election of students 1 group leader and 1 recorder, and be responsible for organizing discussion and cooperative learning. After the group cooperative learning, the Democratic Party recommended 1 students to report the cooperative learning situation to the whole class or teachers, and other students in the group supplemented or corrected it, so that everyone in the group could play a role, give full play to their personal strengths, learn from each other's strong points and improve together. Teachers should also guide students to take turns to play roles according to the actual situation, so that everyone has the opportunity to perform and exercise. Personal ability is limited, and learning tasks can be better accomplished through teamwork.

2 reasonable guidance to improve the effectiveness of group cooperative learning

Teachers are the organizers, guides and collaborators of group cooperative learning. Therefore, it is very important to give full play to the leading role of teachers. Teachers should guide students to put forward cooperative learning goals and cooperative communication methods according to the content of teaching materials, and teach students cooperative learning skills. When group cooperative learning encounters problems, teachers can participate in the group, discuss with students and help students solve the problems. Cooperation and exchange should be carried out on the premise of equality with students. In this way, the feelings between teachers and students are more pleasant and cordial, which is conducive to cultivating students' ability to solve problems, thus improving the effectiveness of group cooperation.
