Abstract

Cylinder is one of the sub-materials in the curved side space building material which is considered quite difficult for students. Students often experience difficulties in understanding concepts, identifying properties, and solving problems related to cylinders. The use of local wisdom in teaching materials can help students understand the material of curved tube side shapes. Therefore, the purpose of this study is to design a learning trajectory to help students understand PMRI-based tube material based on ethnomathematics exploration. This study used the design research method which consisted of 3 stages, namely preliminary design, design experiment (pilot experiment and teaching experiment), and retrospective analysis. The subjects in this study were grade 9 students of SMP Negeri 6 Semarang. The learning trajectory in the context of ethnomathematics exploration consists of identifying cylinder shapes through listening to traditional Sesaji Rewanda stories, determining the surface area of a cylinder, determining the volume of a cylinder, and solving contextual problems related to cylinders. From a series of activities carried out, it can help students understand concepts and solve problems in tube material.
