<![CDATA[Trigonometry instruction in mathematics education is often perceived as abstract and insufficiently interactive, with limited integration of Islamic values. This study aimed to develop and implement a web-based trigonometry learning application integrating Islamic values as a supplementary learning resource. The application integrates instructional materials, interactive quizzes, educational games, and assignments to support student learning. This study employed a Research and Development (R&D) approach using the ADDIE model. Data were collected through lecturer interviews, needs-assessment questionnaires, expert validation, and student-response questionnaires. The application was validated by five experts, comprising two mathematics content experts, one Islamic studies expert, and two media experts, using validation instruments based on a Likert scale. Expert validation indicated that the application was highly feasible, with scores of 93.75% from mathematics content experts, 91.67% from the Islamic studies expert, and 94.50% from media experts. In addition, responses from 21 first-semester students yielded a score of 88.57%, categorized as “Very Positive.” These findings indicate that the developed application met the established feasibility criteria and received positive student responses, supporting its potential use as a supplementary learning resource for trigonometry instruction.]]>
