This article is the result of research aims to describe the patterns and characteristics of the process of metacognition student of mathematics in solving calculus problems. Description was done by looking at changes in "awareness," "evaluation," and "regulation" as components of metacognition. The changes in components of metacognition seen by the emergence of indicators for each indicator were described in descriptors. To see the changes, the researcher used the instrument consisting of calculus problems, metacognition questionnaires, observation sheet, and interviews. Researcher gave calculus to 23 students who followed the course of differential calculus. The research data were in the form of the works of the students, transcript "think-aloud," metacognition questionnaire results, observations using the observation sheet, and a transcript of the interview. Based on research data obtained, the research subjects were categorized in the high-ability students, medium, and low. Data were analyzed using constant comparison method of Glaser and Strauss. Based on data, analysis can be concluded that the pattern and characteristics of the change process "awareness," "evaluation" and "regulation" mathematic students in solving calculus problems can be distinguished in the process of metacognition complete with the order, complete metacognition was not with the order, and metacognition incomplete.
