1. Heterogeneity in the same group: students of different levels are grouped together, which is beneficial for students to help each other, promote each other and improve together, and the progress of activities is relatively unified. Factors to be considered include: grades, abilities, personality differences, gender, class cadre distribution, etc. ?

2. Homogeneity of different groups: maintaining the balance between groups is conducive to communication and competition between groups and to the evaluation of learning activities of each group.

Cooperative learning rules:

First of all, teachers should make clear the special significance of the group and let students know their responsibilities in the group-to contribute to the success of the whole group; Let them know that if one person in the group falls behind, it will affect the performance of the whole group.

Second, teachers should assign tasks and tasks to each group. There is a group leader in the group, whose main responsibility is to divide the work among the group members and organize them to discuss and communicate in an orderly manner. The group leader can rotate, so that every student can get all-round development. Third, we need to communicate in English. Teachers can post a list of commonly used words in class to help students speak, thus preventing communication in Chinese.

In order to better implement the above learning rules, teachers should teach and train students' cooperative skills. Now most students are only children and are used to the life of the "little emperor". Teachers should constantly teach them to respect and accept other people's different opinions, and learn to coordinate their relationship in cooperation, so as to learn from each other's strengths, understand each other and support each other. In addition, teachers must cultivate students to have good cooperative learning habits:

1. The habit of independent thinking, in order to avoid the phenomenon of "conformity" and blind conformity.

2. The habit of actively participating and speaking enthusiastically.

3. The habit of listening carefully.

4. Abide by classroom discipline and cooperative learning rules.
