The purpose of this research are to describe the process of implementation of the Cooperative learning models type Think Pair Share (TPS) to increase the activity and student chemistry learning achievement in class VII A SMP N 2 Kalibawang. Type of research is action research class carried out in two cycles, where eachcycle consist of four stages, namely (1) planning, (2) implementating, (3) observating, and (4) reflecting. The subjects in this research are student of class SMP N 2 Kalibawang, amounting to 32 students while the object in this research is the activity and student learning achievement. Data obtained in this research include: student learning achievement drawn from the test results as the end of cycle and the activity of students drawn from the observation sheets. The results showed an increase in every indicator of student activity proceeds. In the first cycle the average value of the activity indicator of 73,44% increased in the second cycle into 82,81%.
