Pengembangan GeoGebra Classroom Pada Materi Transformasi Geometri

Abstract

This research and development aims to develop GeoGebra Classroom learning media on valid and practical geometry transformation materials. This study involved 5 validators consisting of expert lecturers and mathematics teachers and 21 students of SMAN 2 Cianjur who were the subject of a limited trial. Data were collected using product validity instruments and product practicality instruments. The collected data were analyzed using percentage values which were converted into qualitative form using the criteria of product validity and practicality. The results of this study inform that the GeoGebra Classroom on the geometry transformation material developed is very valid with a percentage value of 93.00% and very practical with a percentage value of 85.87%. Following up on the findings of this study, the GeoGebra Classroom is suitable to be used as a medium for learning mathematics in the classroom as well as for student self-study.
