Abstract

Mathematical problem-solving ability is a crucial competence in 21st-century education. However, many elementary school students still experience difficulties in connecting mathematical concepts with real-life contexts because classroom instruction often emphasizes procedural knowledge rather than meaningful understanding. This study aims to design a PBL-RME-STEAM learning framework to enhance mathematical problem-solving skills in elementary education. The study employed a design-based research (DBR) approach consisting of four stages: analysis, design, development, and evaluation. The framework integrates the principles of Problem-Based Learning (PBL), Realistic Mathematics Education (RME), and STEAM education to facilitate contextual problem situations, mathematical modeling, and collaborative investigation. The research produced a learning framework and instructional materials, including lesson plans and student worksheets. The design was validated by two mathematics education experts and three mathematics teachers with master^s degrees. The validation results showed that the developed framework and instructional materials achieved a high level of validity and feasibility (M = 4.8/5), indicating that the framework is highly appropriate for implementation in elementary mathematics learning. The proposed framework provides both conceptual and practical guidance for implementing contextual and interdisciplinary mathematics learning.
