Analysis of the Difficulty of Students on Visualization Ability Mathematics Based on Learning Obstacles

Abstract

—This research based on the students who have a difficulty solving Sistem Persamaan Linear Tiga Variabel (SPLTV) problems. The difficulty can be seen from the mistakes made by students when solving SPLTV problems. Student mistakes result in learning obstacles when understanding and solving SPLTV problems. One factor causing this to happen is the lack of students' mathematical visualization abilities. This research aimed to determine the students' mathematical visualization abilities based on ontogenic obstacles. The method used in this research is a qualitative descriptive method by identifying answer mistakes made by students when conducting a written test in the form of a description of the questions then the results of the answers are analysed according to learning obstacles that occur in students. The analysis was also strengthened by the answers of the students' interviews. The results showed that there were jumps in thinking experienced by students in the form of jumps from arithmetic thought patterns to algebraic mind-set. Which is a learning obstacle that is ontogenic obstacles. So in general students' mathematical visualization abilities based on ontogenic obstacles experienced by students are relatively low.
