Abstract

The development of technology 4.0 plays an important role in education, increasingly sophisticated technology is a means to produce learning media. The role of learning media in the teaching and learning process is very important for educators today, one of the learning media is Geogebra Software. This study aims to produce mathematics learning media assisted by Geogebra Software in the form of learning videos on the material tangent to a circle for class VIII junior high school students that are tested valid. This study develops learning media using the ADDIE model which consists of 5 stages, namely Analysis, Design, Development, Implementation, and Evaluation. In the ADDIE model, researchers did not use the Implementation and Evaluation stages due to the Covid-19 pandemic so that the learning process was carried out online. The instrument of data collection in this research is the validation sheet of learning media. The nontest technique in the form of a questionnaire is a data collection technique used in this study involving 2 Mathematics Education Lecturers and 2 Mathematics Teachers. Data analysis technique The research is quantitative descriptive analysis. The results of the analysis of the media aspect is 82.65%, content aspect is 90.15% and language is 85.41%, so the overall average is 85.87%. Based on the results of research and development can concluded that the validation results of learning media assisted by Geogebra Software on the material tangent to a circle for class VIII junior high school students are included in the category very valid.
