This Classroom Action Research aims to improve students' HOTS (High Order Thinking Skills) and Social Studies learning outcomes through the application of Carousel Feedback and Round Table cooperative learning methods. This study was based on a model proposed by Elliott and was implemented for three cycles. The subjects were 30 female students of the eight graders of Junior High School Islam Terpadu Darul Azhar, South East Aceh, Aceh, Indonesia. The data collection instruments include observation, test, interview, and documentation. The data were obtained from pre and post-test of each cycle. The findings revealed that Carousel Feedback and Round Table cooperative learning models could increase students' HOTS and Social Studies learning outcomes. The habit of giving time to the students to think, providing scaffolding, observing students' activity, asking questions, discussing in groups, analyzing the results and providing feedback are the examples of activities that should be familiarized.
