Cooperative learning involves small groups working together to improve their understanding of a subject. Each member is responsible for their own learning and helping others. Collaborative learning also involves groups working together, but is based on the idea that learning occurs through social interaction and discussion within the group. Both approaches aim to make learning more participatory by giving students active roles rather than having them passively receive knowledge. The key differences are that cooperative learning divides work among group members, while collaborative learning involves more discussion and joint problem solving.
