The Development of Mathematics Textbooks Based on the Integration of Science and the Qur'an in Madrasah Aliyah

This study investigates the development of a mathematics textbook that integrates Qur'anic science and spiritual values with national curriculum standards at Madrasah Aliyah Darut Taqwa Sengonagung Pasuruan. The aim of the research is to assess the current use of textbooks in grade X mathematics, design a new textbook that incorporates Qur'anic teachings, evaluate its effectiveness in enhancing students' understanding of mathematical concepts, and gather feedback from students and teachers. Using the Research and Development (R&D) method with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation), the study reveals that the existing mathematics textbook lacked integration of religious and spiritual values despite students' strong religious backgrounds. The newly developed textbook addresses this gap by combining mathematical principles with Qur'anic values. Expert validation confirmed the textbook's content, language, and media quality. Field testing showed that its implementation significantly increased student engagement, interest, and academic performance, with an N-Gain score of 0.43, indicating substantial positive impact.
