The instructional methodology known as Cooperative Learning is, of course, cooperative. Implementing extensive Cooperative Learning strategies effectively in the classroom takes skill, however. I recommend Designing Groupwork, Strategies For the Heterogeneous Classroomby Elizabeth G. Cohen (Teacher’s College Press ©1986). Among quickie cooperative learning strategies, I like the following

• Jigsaw
• Fishbowl
• Collaborative Concept-Webbing
• Brainstorming of all kinds
• Mural-making
