Abstract
The aim of this study was to analyze the effectiveness of learning materials through Realistic Mathematics Education Assisted by Geogebra Software (PBRME-G), as well as improving students’ mathematic problem solving ability. Learning materials developed were lesson plan, student book, student worksheet and mathematic problem solving ability test instrument. This research is a development research using the development model of Thiagarajan 4-D model. Learning materials that have met valid criteria according to experts, were tested in class X of SMK Swasta Harapan Mekar 1 Medan. The results of the analysis of the data obtained indicate that learning materials based on PBRME-G met the criteria of effectiveness and can improve mathematic problem solving ability. Based on the results of the study, it was suggested that mathematics teachers make an effort mathematic learning using learning materials based PBRME-G.
