DESAIN PEMBELAJARAN BANGUN RUANG SISI DATAR MELALUI PROBLEM BASED LEARNING BERBANTUAN GEOGEBRA

Abstract

This study aims to determine the use of the context of "cake" in learning flat-sided space, designing Hypothetical Learning Trajectory (HLT), and student perceptions of the integration of geogebra software in learning flat-sided space. The type of approach used in this research is Design Research. The essential characteristic  of  design  research  is  that  it  is  cyclic. The research subjects in the preliminary teaching were observed students' responses to the learning that had been designed and the initial HLT was tested to see students in passing the learning trajectory involving class VII Rasuna Said. The teaching experiment is a situation in actual teaching with the application of the revised HLT results involving class VII Jenderal Sudirman. The results of the data obtained were analyzed qualitatively. The results of the retrospective analysis showed that the use of cake context in learning flat-sided space through problem-based learning found problem solving and helped students in the connection between real-life contexts such as cakes with flat-sided space building material and made it easier for students to understand geogebra-assisted material.
