<![CDATA[The purpose of this study was to improve the learning outcomes of biology through the rotating trio exchange learning model for class XI students of SMA Negeri 23 Maluku Tengah. This research was conducted in the 2020/2021 school year. This type of research is classroom action research. As a subject, students of class XI totaled 24 students. The research was carried out in 2 cycles and each cycle consisted of 4 stages, namely; planning, implementing, observing, and reflecting. The results obtained indicate that the application of the rotating trio exchange model carried out is evident from the completeness of the learning outcomes of the first cycle students by 25% and at the end of the second cycle has increased to 100%. The score of the observation of student learning activities in cycle I was 54.17%, and at the end of the second cycle it increased to 95.83%, which means that it was categorized as very good.
