Leveling Of J Unior High School Student Mathematical Communication In Solving Open Ended Problem

This research aims to describe the leveling of students’ mathematical communication in solving open ended problem on geometrical problem. This qualitative research took 2 students of VIII MTS Maslakul Huda Sluke, Rembang municipal as the subjects. The subjects were selected based on varieties of students in communicating mathematical ideas both written and spoken. The steps to select subjects were: (1) providing open ended problem solving questions with geometrical material, (2) conducting interview based on task to confirm students answers revealed in written, and (3) categorizing the subjects into 4 levels. The data collection techniques were problem solving task and interview. The data analysis used qualitative data analysis. The findings showed that: (1) students’ mathematical communications both written and spoken were at level one. It was students’ explanations in solving open ended problems of geometrical materials were limited only on several concepts, (2) students’ explanations in solving the problem were partially correct.
