Abstract

This study aims to develop and produce valid and practical teaching materials on circles using GeoGebra for students and teachers in grade XI at MAN 2 Tanah Datar. The research method used was Research and Development (R&D) by adapting the 4D development model, which was limited to three main stages, namely Define, Design, and Develop. Data collection instruments included a validation sheet for experts and a practicality questionnaire. The data analysis technique used was a percentage formula for validity analysis and practicality analysis. The results showed that the teaching materials developed had a validity level of 87.12% with a very valid criterion. The level of practicality through trials at MAN 2 Tanah Datar showed an average student response score of 85.13% (very practical) and a teacher response of 79.63% (practical). Based on these results, it can be concluded that this GeoGebra-assisted Circle teaching material is feasible and very practical to use as a support for the mathematics learning process at the school. The implication of this research is the availability of interactive learning media that can help students visualize circle concepts with the aid of technology.
