Reasonable grouping is the premise of successful cooperative learning. In order to carry out effective group cooperative learning, students must be grouped reasonably first. Because there are differences in personality, gender, academic performance, learning ability, etc., the composition of the group should be decided by teachers and students, taking into account students' performance, personality, gender, communication ability and other factors. It is necessary to guide students to learn to get along with different people, especially those with poor communication skills and unsatisfactory academic performance, and strive for the progress of students in the group, requiring every member of the group to devote himself wholeheartedly and participate in the whole process. The number of people in each group should be appropriate and adjusted once every semester. The author divides the whole class into 10 groups (4 people in each group), appropriately shifts the students' seats according to the groups, and then combines them in the order of seats. This method is relatively simple to operate, the team members are relatively fixed, and the team leader can take turns.
