Integrating Islamic Values and Mathematical Communication Skills in the Relations and Functions Module

Abstract

In Islamic-based schools, mathematics instruction should be supported by engaging modules that encourage independent learning and integrate Islamic values with mathematical communication skills, enabling students to convey mathematical ideas effectively. This study aims to develop a valid, practical, and effective mathematics module integrating Islamic values and mathematical communication skills for the topic of relations and functions, and to determine students’ level of Islamic knowledge after its use. This research and development (R&D) study used the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation) and a One-Shot Case Study design for effectiveness testing. Conducted at SMPIT Az-Zuhra Islamic School Pusat, the subjects included eighth-grade students and experts. Data were collected via validation sheets for instructional material experts, Islamic studies experts, and educational technology experts, along with practicality and Islamic knowledge questionnaires, and a mathematical communication skills posttest. Data were analyzed using the Aiken index (validity), percentages (practicality and Islamic knowledge), and normality and one-sample t-tests (effectiveness). The module achieved a validity level of 0.83 (highly valid). Practicality reached 93.87% (small group) and 90.25% (limited group), both categorized as highly practical. Posttest results showed an average score of 79, exceeding the learning objective achievement criteria (KKTP) of 78. The one-sample t-test (〖-t〗_table<t_calculated, specifically -1.6753<0.3674) confirmed its effectiveness. Furthermore, students’ Islamic knowledge fell into the "very good" category. Thus, the developed module is valid, practical, effective, and suitable for mathematics education.
