Development of a web-based learning application for a trigonometry course with integrated Islamic values

Abstract

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.
