Abstract

Abstract

This research aimed to describe students"™ mathematical reasoning ability on the solid geometry matter of XII Grade MIPA SMA Negeri 4 Pontianak. The research method used was descriptive and the form of this research was case study. Subject of this research was students of XII MIPA 2 Class which consist 32 students. The techniques of data collection were mathematical reasoning ability test and interview. The results in this research shows that students"™ mathematical reasoning ability fall into the medium, low, and very low category, because there are 7 students (21,88%) were in very low category, 6 students (18,75%) were in low category, 17 students (53,13%) were in medium category, 2 students (6,25%) were in high category, and no students (0%) were in very high category. Some affect the students mathematical reasoning ability were in medium, low, and very low category because some students have not been able to form a conjecture and gives reason on their conjecture, most of the students can"™t mathematic manipulating, and some students can"™t finding a patterns against a mathematical phenomenon.
