The development of technology in the twenty-first century has progressed very rapidly. Technological advancements in indinesia have had a significant impact on various aspects of life, include the field of education. Education is one of the efforts to improve the quality of individuals in order to face the advancement of science and technology. This study aims to develop and produce interactive learning media based on Geogebra in mathematics subjects and to determine student learning outcomes in mathematics subjects. This type of research is research and development (R&D) which refers to the ADDIE development model. Based on the results of the study, the validation of learning media obtained a total average of 3.71 including the very valid category, while the validation of the material obtained a total average of 3.76 including the very valid category, thus the learning media was declared valid. The learning media was declared practical based on the very positive and very good responses given by students and mathematics teachers, which were 3.62 or 89.61% and 3.87 or 96.87% respectively. The learning media was declared effective because it was able to improve students' mathematics learning outcomes as seen from the increase in the average student mathematics learning outcomes before and after using the learning media from 34.09 to 76.80 and the n-gain result of 0.65 which showed an increase in students' mathematics learning outcomes included in the "moderate" category. Based on the results of the research and development model, Geogebra media can be considered valid, practical, and effective.
