The Effect of Van Hiele Learning Model Based Geogebra on Students’ Spatial Ability

Abstract

This research aimed to discover the effect of Model Van Hiele Based Geogebra on Students Spatial Ability. The population of this research is all Students at University Muhammadiyah of Prof. DR. HAMKA. The sample in this research are students of the second semester of the mathematics education study program. This research was conducted online due to COVID-19. The research method used is quasi-experimental. Data collection used a mathematical spatial ability test instrument. The data analysis technique used a t-test. The result showed that students mathematical spatial ability treated with the Model Van Hiele Based Geogebra was not higher than whose mathematical spatial ability of students treated with the conventional models. That is due to several factors, namely internal and external factors.
