<![CDATA[Despite the growing interest in contextualizing mathematics education, research integrating Qur’an contexts into mathematics instruction remains limited. Prior studies have largely concentrated on conventional teaching methods, Qur’an-centered instruction, or Problem-based Learning (PBL) as independent approaches. This study addresses a critical gap by integrating Qur’an contexts into integer learning, supported by problem-based learning and facilitated through a technology-enhanced Electronic Student Worksheet (E-SW). The primary objective of this study is to design and assess the reliability and applicability of a Quran-based E-SW using the PBL framework for teaching integers to 7th-grade junior high school students. Employing a Research and Development (R&D) methodology with the ADDIE development model—comprising analysis, design, development, implementation, and evaluation phases—this research utilizes expert validation sheets and student practicality questionnaires as instruments. The study sample consists of 7th-grade students from SMP IT LHI Yogyakarta, with class 7B selected through purposive sampling. Validation results indicate that the E-SW meets established validity criteria, with scores from subject matter and media experts reaching 99 and 91, respectively, both classified as "Good." Practicality testing revealed positive student responses, yielding a practicality score of 61, categorized as "Practical." Furthermore, a paired sample t-test demonstrated a statistically significant improvement in student performance between pretest and posttest results, with a significance (2-tailed) value below 0.05 and an average N-Gain score of 0.4391, which is classified as moderate. These findings suggest that the Quran-based E-SW, structured around the PBL model, effectively enhances students' problem-solving abilities and is suitable for educational use.]]>
