Abstract

The background of this study is the difficulty of teaching mathematical concepts in topics that require spatial skills. Flat-sided three-dimensional shapes are one such topic that requires strong spatial skills. One alternative teaching approach that can be applied is Realistic Mathematics Education (RME). This study aims to design a learning trajectory for the topic of flat-sided three-dimensional shapes. The research method used is design research, consisting of three stages: preparation, design experimentation, and retrospective analysis. This study involved five eighth-grade students at a Madrasah Tsanawiyah. The study formulated a hypothetical learning trajectory (HLT) consisting of three student learning activities: 1) explaining the differences between the elements of prisms and pyramids; 2) understanding the concepts and determining the surface areas of prisms and pyramids; and 3) explaining and determining the volumes of prisms.
