This study aimed to develop Scratch-based interactive learning media for applied algebra using the 4D development model, consisting of the define, design, develop, and disseminate stages. The research addressed students’ difficulties in understanding and applying algebraic concepts in contextual problem-solving and the limited availability of interactive digital learning media. The development process involved needs analysis, prototype design, and media implementation using Scratch with interactive materials and game-based exercises. The feasibility of the media was evaluated through material and media validation conducted by mathematics education lecturers. At the same time, user acceptance was examined through a User Acceptance Test (UAT) involving ten prospective mathematics teachers. Data were analyzed using percentage-based scoring. The results indicated that the developed media achieved a very good level of feasibility in terms of material quality, content coverage, instructional design, ease of use, and visual aspects. The UAT results also showed a very high level of user acceptance across functionality, program presentation, and language and typography aspects. Furthermore, evaluation using the Dr. Scratch application yielded a score of 20 out of 21, placing the media in the Master category. These findings suggest that the Scratch-based interactive learning media is feasible and well accepted, with potential to support motivation, mathematical learning performance, and the development of computational thinking in applied algebra learning.
