Students have different geometric thinking abilities when studying geometry. According to Van Hiele's theory, the ability to think geometrically is grouped into 5 levels, namely level 0 (visual), level 1 (analysis), level 2 (formal deduction), level 3 (informal deduction), and level 4 (rigor). Appropriate tastes, of course, support individuals' ability to think geometrically. In the choice, there are 2 categories, namely affirmatory intuition and anticipatory intuition. This study will describe the ability to think geometrically in terms of student intuition. This research method is descriptive qualitative. The subjects of this study were third-semester students of the mathematics education study program at a private university in Semarang who had taken a spatial geometry course. The data were obtained from the Van Hiele level evaluation tests, observations, and interviews, which were then triangulated. The interview subjects were taken by three students based on each level of geometric thinking. The results showed that students were at level 1, level 2, and level 3. At level 1, students tended to use affirmatory intuition. At level 2, students use affirmatory and anticipatory intuition. At level 3, students use affirmatory and anticipatory intuition. Further research needs to increase geometric thinking skills by training students' intuition. [ABSTRACT FROM AUTHOR] |
