Abstract
The aims of this research was to find the effectiveness of learning devices based on realistic mathematics education, as well as improving mathematic spatial ability and motivation of SMP Negeri 2 Pulo Bandring students’ grade IX. This research is a development research using the Dick & Carey development model. The results of the analysis of the data obtained indicate that learning materials based on realistic mathematics education met the criteria of effectiveness, it was found that students completed classically ≥ 85% of students got a minimum score of ≥75, achievement of learning objectives, positive students responses and learning time equal to ordinary learning. Based on the results of the study, it was suggested that mathematics teachers make an effort mathematica learning using learning devices based on realistic mathematics education.
