abstract={This study aims to analyze the effectiveness of learning media using a <i>Geogebra</i>-assisted realistic approach to improve the mathematical spatial abilities of junior high school students. This type of research is a research development using a modification of the development model of Thiagarajan, Semmel and Semmel (1974). The stages of this research are define, design, develop, and disseminate. In this study compiled learning tools and instruments, namely: RPP, LAS, <i>geogebra</i>-assisted learning media, spatial ability tests. Try out conducted at student of class VIII-7 as much 40 people and VIII-6 as much people at MTsN 2 Medan. The results showed that learning media using a <i>Geogebra</i>-assisted realistic approach met the effective criteria of completeness spatial ability reaching 87.5% and learning time not much different from the usual learning time.},
