The purpose of this research is to analyze: 1) the students metacognitive ability in mathematical problems solving, 2) difficulties experienced by students’ metacognitive in mathematical problem solving, 3) process of students’ metacognitive answer in mathematical problem solving. This research is as qualitative descriptive research aimed to describe the students’ metacognitive ability in mathematical problem solving with problem-based-learning model. Subject in this research is class VII in SMP Negeri 4 Bendahara Aceh Tamiang. The subjects consisted of four students; one in high-ability student, one medium-ability student, one low-ability student, and one with the most wrong answers. The data is obtained from the essay test and depth interview. While the object of ths research is the students’ metacognitive ability in problems solving by learning mathematics with problem based learning model on the subject of integers and fractions. based on the analysis of research data, the result that: 1) the mathematical problem solving ability of students with high category at the level of metacognitive Strategic Use, the students medium category at the level of metacognitive Aware Use, and low category at the level of metacognitive Tacit Use. 2) metacognitive difficulties experienced by students in solving mathematical problems include difficulty facts, concepts, principles, and procedures.
