Kata Kunci: hasil belajar matematika, numbered heads together (NHT) Abstract This study aims to disclose information and discuss the improvement of Mathematics Learning Outcomes through the Numbered Heads Together (NHT) Cooperative Learning Model for Class XI Science 1 SMA Negeri 7 Bengkulu City. This type of research is classroom action research (CAR). The main characteristic of classroom action research is that there are certain actions to improve and perfect the learning process in the classroom. This research consists of two cycles, each cycle contains four activities, among others; (1) Planning, (2) Action Implementation, (3) Observation, (4) Reflection. This research was carried out at SMA Negeri 7 Bengkulu City. The subjects in this study were students of class XI IPA 1 SMA Negeri 7 Bengkulu City, totaling 36 people. This research was conducted in the odd semester of the 2020/2021 school year. Data collection in this study was carried out using field notes, student worksheets, written tests, and documentation. The data analysis technique uses the percentage formula. The results of this study indicate that the increasing of student learning outcomes in mathematics Rafter they studied through Numbered Heads Together (NHT) cooperative learning model. This can be seen from the students' understanding and mastery of the material that has been delivered by the teacher so far. Students' learning mastery increased from pre-cycle, first-cycle, and second-cycle, which were 38%, 67%, and 86%.Keywords: Mathematics Learning Outcomes, Numbered Heads Together (NHT)
