Developing learning trajectories with the RME of phytagorean theorem

Abstract

Abstract There are three main parts of the hypothetical learning trajectory (HLT), are (1) learning objectives, (2) learning activities, (3) student understanding and problem solving strategies. The researcher tried to develop a context that helped students in finding the concept of the pythagorean theorem using the RME approach. In this study, the type of research used by researchers was design research developed by Gravemeijer and Cobb. There are three phases in design research according to Gravemeijer and Cobb, namely preliminary design, experimental design, and retrospective analysis. In this paper, researchers describe limited to the first phase of design research.
