The method of this study was design research type validation studies which were aimed to prove the learning theories. Research design consisted of three phases, those are preliminary, experiment design, and retrospective analysis. This research was conducted in SD negeri 3 OKU by involving fifth grade students. The data of this research was collected by using video, documentation, pre-test, the students’ activity sheets, post-test, and interview. The data were analyzed qualitatively.
