Development of learning media based on Geogebra software on the topic of trigonometric ratios

Abstract

In line with the development of information technology, mathematics learning innovations need to be continuously carried out by teachers and researchers. The topic of trigonometric ratios is one of the difficult math topics for students, so it is necessary to make learning media so that students are easy to learn. This study aims to develop interactive learning media based on Geogebra on the material of trigonometric ratios. The type of research used is research and development (R&D). This learning media development model was developed based on the ADDIE (Analysis, Design, Development, Implementation, Evaluation) development model. The test subjects in this study were grade 10 vocational high school students. Based on the results of trials conducted on the developed media, data obtained from the validation results of media experts with an average of 3.59 and being in the valid category. The results of the student response questionnaire showed that the Geogebra software-based learning media received a positive response with an average score of 3,48 so it was in the practical category to use. The implementation of learning with the help of Geogebra software gets an assessment of 3,46, so it is in the good category. The results of this development research can be utilized by teachers or researchers in the development of mathematics learning on the topic of trigonometric ratios.
