The concept of cooperative learning is an attempt of western educators to develop a group learning method for
increased learning efficiency. Slavin (1995) and Strommen (1995) stated that cooperative learning can be employed
effectively to all levels of teaching and learning facilitation. This included mathematics subject, reading, writing,
and Science subject as well as subjects which need computer to help solve complex problems and facilitate
convenience in cooperative learning. Uslik and Walker (1994) and Serra (1997) claimed that cooperative learning
can be managed in various forms in which it comprises 2-6 learners depending on types of learning activities.
However, one research finds that a group of 4-5 learners is the most appropriate.
