Abstract

Reflective thinking is the ability of a person to select the knowledge he has to solve the problem at hand, starting from analyzing the problem, evaluating, to concluding. This study aims to describe the reflective thinking skills of students of class VIII C SMP N 1 Pundong in solving mathematical problems in the subject matter of relations and functions. This type of research is descriptive qualitative. The subjects of this study were 26 students taken using the purposive sampling method. The results of this study indicate that the percentage of achievement in the first indicator of reflective thinking describes a case based on mathematical concepts of 72.11%. The second indicator of reflective thinking to identify mathematical concepts or formulas involved in mathematical problems is 54.81%. The third indicator of reflective thinking draws an analogy from two similar cases of 24.04%. The fourth indicator of reflective thinking evaluates based on mathematical concepts was 38.46%. And the fifth indicator of reflective thinking makes conclusions using mathematical concepts by 42.31%.
