How to improve the effectiveness of group cooperative learning in primary school mathematics classroom

"Group cooperative learning" is a teaching form to acquire knowledge through division of labor, mutual communication and comprehensive generalization. In the process of group learning, students learn to listen, express and cooperate, learn to learn from each other's strengths, constantly revise their own views and form group opinions. In a word, let the students' personality develop in an all-round way. But in reality, group learning is not satisfactory, and there are many phenomena, such as centralized leadership, lively pseudo-cooperative pseudo-learning, or a stagnant pool. Then, how to make "group cooperative learning" truly implemented and students' personality fully developed? The author believes that there are several ways to strengthen the effectiveness of group cooperative learning in mathematics classroom:

First of all, establishing a cooperative group with reasonable structure is the premise of effective cooperative learning.

Teachers should pay attention to the rationality of the structure when establishing cooperative groups. First, the number of groups should be reasonable, generally four people are appropriate, not more than six people. Too many students are not conducive to the organization and communication between students, and there are bound to be spectators in group learning and communication, especially some students with introverted personality or low consciousness, which is not conducive to the development of these students; Too few people can't achieve the purpose of communication; Second, grouping should follow the principle of "taking advantage of disadvantages, promoting disadvantages with advantages, and competing within groups". Teachers should group students according to their differences in knowledge base, learning ability and personality characteristics, so that students with different characteristics and levels can be optimally combined, so that each group has high, medium and low level students. This grouping not only helps students complement and promote each other, but also lays the foundation for fair competition among all groups in the class. Third, team members should be energetic. You can change roles according to the individual characteristics of the members in the group during the learning process, or you can recommend a new group leader according to the performance of the students in the group, and the former group leader will assist in cooperative learning. This not only makes students feel fresh, enhances their interest in cooperative learning, but also changes their long-term position in the group, that is, some students are always in a controlling position and some students are always in a subordinate position, which provides opportunities for each student to develop.

Secondly, making an orderly cooperation procedure is the guarantee of effective cooperative learning.

In class, this phenomenon often happens. After the teacher asks questions, let the students discuss them immediately, and there will be a heated discussion in the classroom immediately. But with a little attention, it is not difficult to find the disorder after this false excitement. Some groups, several people express their opinions at the same time, and don't listen to others at all, let alone cooperate; In some groups, only two better students are discussing, while others do nothing; In some groups, you push me around and wait. The main reason is the lack of rules in group cooperative learning.
