Abstract


Problem solving strategies have an important role in the process of mathematical problem solving. Mathematical problem solving strategies is a method used in the process of solving mathematical problem to find solution to mathematical problems. The purpose of this study is to describe the mathematical problem solving strategies of junior high school students in terms of high, medium, and low mathematical abilities. This research is a qualitative descriptive study. Subjects in this study consisted of three student of class IX  junior high school even semester. The instrument in this study was a mathematics ability test, mathematics problem solving test, and interview guidelines. This research was started by giving a mathematical ability test to categorize students into high, medium, and low mathematical ability groups. Then, each student is given a problem solving test. From the result of the test, each student was chosen from the category of mathematical ability group to be the subject of research and interviewed. Consideration of taking the subject is based on student strategies when completing a mathematical problem solving test that is student who use the most strategies out of all students in each category of mathematical ability. Beside that, another consideration is that the student can solving questions correctly and have good communication skills. The result in this study indicate that, 1) student with high mathematical ability in solving mathematical problems using strategies making a drawing, logical reasoning, guess and test, and finding a pattern. 2) Student with medium mathematical ability in solving mathematical problems using strategies making a drawing and logical reasoning. 3) Student with low mathematical ability in solving mathematical problems using strategies making a drawing. This research provides an understanding of mathematical abilities as well as improving the selection and use of strategies to solve mathematical problems.
