This study aims to improve collaboration in thinking, pairing, and sharing of students in energy conversion learning. This study experimented with the think pair and share (TPS) type of cooperative method to get improvements in terms of activity and cooperation. The procedure of the study adopted the classroom action research of the Kemmis & Taggart model covering the stages of planning, implementation, observation and reflection. Data collection techniques using observation and documentation. The results showed that the application of the cooperative learning model type TPS method was able to increase collaboration in thinking, pairing, and sharing as evidenced by the results of observations of each cycle which increased the first cycle of 12.5% for student involvement and 25% for collaboration, the second cycle of 78,1% for student involvement and 53.1% for cooperation, and third cycle of 96.9% for student involvement and 100% for cooperation. It shows that the application of TPS is useful to be applied in energy conversion learning. Also, this research may need to be continued in other engineering courses which are dominated by theory and practicum.
