<![CDATA[This study aimed to develop GeoGebra-assisted interactive learning media on the topic of gradients for junior high school students that are valid and practical for use in mathematics learning. This research employed the Research and Development (RD) method using the 4D model, which consists of the define, design, develop, and disseminate stages. The trial subjects consisted of 15 eighth-grade students of SMP Negeri 1 Tanjung Pura. The research instruments included media expert validation sheets, material expert validation sheets, and student response questionnaires. The results showed that the developed media met the validity criteria based on the media expert validation results with an average score of 3.61 and the material expert validation score of 3.66. In addition, the media received positive responses from students with an average score of 3.63, indicating that it was practical for use in learning activities. The GeoGebra-assisted interactive learning media was able to help students understand the concept of gradients visually and interactively. Therefore, the developed media is feasible to be used as an alternative mathematics learning medium in junior high schools.]]>
