A teacher is expected to know and understand about learning models and always be innovative in applying them in learning activities. Therefore, teaching mathematics in the old way, teachers who are active and continue to transfer their knowledge into the minds of students, it is time to replace it with a new way, learning must be student-centered, how students should learn one of them through cooperative learning. According to (Hudojo, 1998:5) "With the cooperative learning model, students are given the widest opportunity to develop themselves. It is time for the teacher as a knowledge provider to turn into a facilitator who facilitates students to be able to learn to construct their own knowledge. The question arises whether cooperative learning is effective in learning a two-variable system of linear equations? Can students develop or construct their own knowledge?

Related to this problem, an effective and appropriate learning model is STAD (Student Team Achievement Divisions) cooperative learning. According to Slavin (in Soedjadi, 1999:155) “STAD can be successful because this program teaches both group and individual efforts. So that the group is responsible for the individual learning of each group member. The group in STAD is a heterogeneous group consisting of a mixture of students according to performance level (high, medium, and low ability students), gender and ethnicity.It can be concluded that the STAD cooperative learning model is more effective than the conventional learning model in learning a two-variable linear equation system in class VIII of SMP Negeri 1 Darul Kamal. STAD TYPE cooperative learning makes students more active in class discussions compared to conventional learning.
