<![CDATA[This research was conducted with the aim of improving the biology learning outcomes of class XI IPS 1 students in the 2018/2019 academic year at SMA Negeri 1 Merangin through the STAD type cooperative learning model. This research is a Classroom Action Research (CAR). The subjects of this study were students of class XI IPS 1, totaling 28 students. The research was conducted in two cycles and each cycle consisted of two meetings. Data collection techniques in this study used observation sheets, diary journals, and tests. The data obtained were analyzed by means of reduction, data exposure and conclusions. Descriptive data analysis was also carried out for observational data and daily journal entries.
