The study reports about the effectiveness of metacognitive-based learning model in learning mathematics covering learning completeness, students’ learning activities, teacher’s learning management skill, and students’ response. Metacognitve-based learning model is model applied in learning mathematics optimizing the student’s metacognitive skill, including five phase; (1) orientation, (2) presentation and information, (3) simulation, (4) guided training, and (5) self-training. The population of this study was taken from all of the Eleventh Year Students of SMA Negeri 4 Parepare in 2016/2017. Both samples of experimental and control class consist of 24 students for each. The data were analyzed by descriptive and inferential statistics. The result of this study shows that the results of the analysis shows that the results of learning mathematics of students who are taught by applying the model of learning model of metacognitive skills-based learning is better than the result of learning mathematics students who taught without applying a model of metacognitive skills-based learning on mathematical material.
