Abstract
Mathematics learning on exponent material still faces challenges in terms of understanding abstract concepts, low student learning motivation, and limited interactive learning media. This study aims to: (1) develop interactive Scratch-based learning media using the MDLC model on exponent material, (2) determine the level of validity of learning media according to media and material experts, and (3) determine the level of practicality of learning media according to students. This type of research is Research and Development (R&D) using the Multimedia Development Life Cycle (MDLC) development model, which consists of six stages: Concept, Design, Material Collecting, Assembly, Testing, and Distribution. The research subjects are 2 lecturers as validity subjects and 17 students as practical subjects. The research instruments are media and material expert validation sheets, and student practicality questionnaires. The data analysis technique uses descriptive analysis for validity and practicality. The results of the study showed: (1) interactive learning media assisted by Scratch was successfully developed through six MDLC stages with interesting interactive features and in accordance with the characteristics of junior high school students, (2) the learning media obtained a validity level of 97.5% from media and material experts with the category ^very valid^, (3) the learning media received a practical response of 82.9% from students with the category ^very good^. Interactive learning media, Scratch-based on the topic of exponents, has been proven to be valid and practical, so it can be recommended as an alternative, innovative mathematics learning media.
