This research aims to determine the effectiveness of Accelerate Learning Cycle (ALC) model on the mathematics learning outcomes at the seventh-grade students of SMP Mahaputra Tello Makassar. The type of research was pre-experimental research. The sample of the research was the seventh-grade students of SMP Mahaputra Tello Makassar. Data processing used descriptive statistics, the average score of students' mathematics learning outcomes by applying the Accelerate Learning Cycle (ALC) model of 50.65 was in the less category. Meanwhile, students' mathematics learning outcomes after applying the Accelerate Learning Cycle (ALC) model increased in the medium category after seeing the gain value of 0.6 with an average score of 79.94 mathematics learning outcomes in the medium category. Students’ activities during the implementation of Accelerate Learning Cycle (ALC) model were in the active category and student responses after the implementation of Accelerate Learning Cycle (ALC) model were in positive category. Based on these results, it can be concluded that the Accelerate Learning Cycle (ALC) model was effective on mathematics learning outcomes of the seventh-grade students of SMP Mahaputra Tello Makassar.
