Abstract

Purpose – This study describes seventh-grade students’ mathematical connection ability in rational number topics at an Islamic Integrated Junior High School in Pekanbaru, prompted by recurring difficulties with cross-conceptual and contextual problem solving. Methodology – Using a descriptive qualitative design and purposive sampling, three Grade VII students were selected to represent high (DP), medium (KY), and low (IS) achievement. Data were gathered through a written test (three rational-number tasks) and in-depth interviews guided by NCTM (2000) mathematical connection indicators. Analysis included data reduction, indicator-based coding, test–interview triangulation, and conclusion drawing. Findings – DP satisfied all three indicators consistently. KY met some indicators but showed weaknesses in symbolization and contextual application. IS showed limited connections within mathematics, across disciplines, and to daily-life situations. Connection ability varied with conceptual understanding and independence, suggesting the need for more contextually and integratively focused instruction on rational numbers. Novelty – The study offers detailed qualitative profiles of mathematical connections in rational numbers across three distinct ability levels using NCTM (2000) indicators. Significance – Results support teachers, curriculum developers, and researchers in designing learning tasks and interventions that explicitly cultivate mathematical connections.

Abstract

The aim of this study is to develop a mathematics learning module based on the RBL model that incorporates Islamic values, specifically for the topic of compound probability. Additionally, the study seeks to determine whether the module is valid and effective in enhancing students' conceptual understanding. This study was motivated by students' low conceptual understanding of compound probability and the limited availability of independent, Islamic value-integrated learning materials based on RBL syntax. This study employs a Research and Development (R&D) approach based on the 4-D model, which comprises the stages of Define, Design, Develop, and Disseminate. The research subjects consisted of 22 students from class XI at MA IBS Riau. After data were collected using expert validation sheets and pre-test and post-test scores, a descriptive quantitative method was used to analyze them. The results showed that the developed module achieved an overall validity score of 84.29% (categorized as "very valid"). The effectiveness test yielded an average N-Gain score of 0.6914 (moderate category), with 77.3% of students achieving moderate-to-high learning gains and a classical mastery level of 54.55%. These results indicate that the RBL-based mathematics learning module, which incorporates Islamic values ​​into the topic of compound event probability, possesses a satisfactory level of validity and effectiveness. They also demonstrate its suitability as an alternative resource for independent learning, particularly in Islamic boarding schools
