Cooperative learning is an instructional strategy where small teams of students work together on learning activities. It supports students of all ability levels and needs. Examples of cooperative learning activities include Round Robin, where students take turns contributing items to a category, and jigsaw activities, where each student researches a part of a topic and shares it with their group. The benefits of cooperative learning include developing higher-order thinking skills, increasing retention, building self-esteem, and promoting social and communication skills.
