Abstract:

The purpose of this study was to describe critical thinking process of students in solving mathematical problems based on the framework of Polya. Therefore, this study classified as a descriptive qualitative research. These research subjects were 32 junior high school students of grade 7. The data collection begins with students solving mathematical problems about geometry (trapezoid). If in the process of completion, students experiencing the critical thinking they would be selected as the subject of study and further their thinking process explored. The occurrence of critical thinking in students characterized by the student's behavior that constructs and evaluate the strategies used to solve the problem. The results showed that the students' critical thinking process in solving mathematical problems with the framework of Polya include low critical thinking, medium critical thinking, and strong critical thinking.
