The Effectiveness of JERAMAT Learning Management System Integrated with PBL-STEAM to Improve Students' Learning Outcomes on Two-Variable Linear Inequality Systems

Abstract

The integration of digital technology into mathematics learning is expected to enhance students' conceptual understanding and engagement. This study aimed to investigate the effectiveness of the JERAMAT Learning Management System (LMS), which integrates Problem-Based Learning (PBL), the STEAM approach, and ethnomathematics in learning Two-Variable Linear Inequality Systems (TVLIS). The study employed a Research and Development (R&D) approach using the ADDIE model involving 36 eleventh-grade students at SMA Negeri 6 Semarang. Data were collected through pre-test, post-test, classroom observations, and documentation, then analyzed using descriptive statistics and the Wilcoxon Signed-Rank Test. The results showed that the average score increased from 39.0 in the pre-test to 67.1 in the post-test. Statistical analysis also revealed a significant improvement in students' learning outcomes (p < 0.001). These findings indicate that JERAMAT is an effective digital learning platform for improving students' understanding of TVLIS through contextual, interactive, and technology-supported learning.
