Abstract

This research aims to describe students' reflective thinking in solving open-ended problems in plane figure. This research is a case study. The subject was seven graders of SMP N 8 Malang 2018/2019. The research instrument was mathematical open ended test about plane figure. Subjects were chosen based on reflective thinking characteristics of the seven graders. The data collection technique was done by giving the test to the subjects, and the subjects solved the test in writing while doing think out loud. Data analysis was done by: (a) reducting data, (b) displaying data (c) making a conclusion. The results showed that the description of students' reflective thinking in solving open-ended problems in plane figure included three characteristics. The first characteristic includes stages: (1) students have difficulty understanding the problem; (2) describe it; (3) compile plans for more than three of these considerations; and (4) implementing a problem solving plan, linking information that is owned by the problem, explaining it well, and checking again. The second characteristic includes: (1) students have difficulty understanding the problem; (2) describe it; (3) draw up a plan on these three considerations; and (4) implementing a problem solving plan, explaining three problem solving solutions, and linking information that is owned by the problem. The third characteristic includes (1) students have difficulty understanding the problem; (2) describe it; (3) develop a plan for each of these considerations; and (4) implementing a problem solving plan, explaining less than 3 problem solving solutions, linking information that is owned by the problem. The implication of this research is to develop the understanding of students and teachers in learning that can improve reflective thinking in solving each mathematical problem solving.
