Thinking about what is thought in this term relates to students' awareness of their ability to develop various ways which may be taken in solving a problem is known as metacognition. The existence of metacognition is very important for students in solving mathematical problems. This is a qualitative study using the grade VII students having medium ability as the subjects. The results of the study obtained that through intervention conducted by the researchers in 5 meetings, metacognition capability emerged in the subjects so that with their own ability they are able to solve mathematical problems provided. Keywords:Metacognition; Problem Solving Every day in our life we must often be faced by problems since problem and problem solving process are parts of the self-maturation process which must be passed and the self-existence of as an individual or as a part of environment. Thus, the ability to solve a problem is a skill which must be owned by someone to be able to take a better life. The discussion in this study is not intended for the whole problems, but rather focuses on problems related to mathematics lesson at school. Problems in mathematics lesson at school is a routine and non-routine problem and related with a given concept and related to mathematics. If a student in the class can solve mathematical problems given during the learning process, the formulation of learning objectives which have been formulated are achieved. Therefore, the ability of students to solve mathematical problems needs to be trained so that students are able to solve existing problems in mathematics. Students need to have problem solving skills (NCTM, 2014; Posamentier & Krulik, 2009). Posamentier & Krulik, 2009say that mathematical problem solving is a basic skill in learning mathematics. Mathematical problem solving is a general goal of mathematics learning, problem solving includes methods, procedures, and strategies are the core and major process in the mathematics curriculum. NCTM (2014) says that problem-solving ability is one of mathematical abilities which students must possess. To assist students in developing problem-solving skills, the important thing which needs to get attention is how the students' thinking process in solving a problem is. Desoete, Roeyers, & Buysse(1996)statement that the main purpose of teaching problem-solving in mathematics is not only to equip students with a set of skills or processes but rather to allow students to think about what they are thinking.
