Abstract

General Background: Education in elementary schools forms the foundation of human resource development, yet mathematics often becomes a major challenge due to students’ limited understanding of abstract concepts. Specific Background: At SDN 027/II Sungai Arang, nearly half of the fourth-grade students failed to reach the minimum competency score in fractions, caused by monotonous, teacher-centered methods and low engagement. Knowledge Gap: While the Indonesian Kurikulum Merdeka promotes student-centered, project-based learning, its empirical implementation in rural schools with limited resources remains underexplored. Aims: This study aimed to improve mathematics learning outcomes in fractions through the application of the Project-Based Learning (PjBL) model. Results: Conducted as Classroom Action Research in two cycles, the study revealed improvements in teacher performance (from 77.27% to 100%), student engagement (increase in highly active students from 6 to 12), and learning outcomes (mastery rising from 64% to 84%). Novelty: Unlike previous studies in better-equipped contexts, this research demonstrates the effectiveness of PjBL in a resource-limited elementary school, highlighting its adaptability and contextual relevance. Implications: The findings suggest that PjBL not only enhances conceptual mastery of fractions but also fosters critical thinking, collaboration, and motivation, thus offering a viable pedagogical strategy for advancing Kurikulum Merdeka in diverse educational settings. Highlights: PjBL improves student engagement and critical thinking. Learning outcomes in fractions increased from 64% to 84%. Effective even in resource-limited elementary schools.

Abstract

General Background: Mathematics is a fundamental discipline that supports technological advancement and cognitive development, yet it remains challenging for many elementary students due to its abstract nature. Specific Background: Observations at SDN 12/II Empelu revealed that Grade IV students showed low learning outcomes, with 47% failing to reach the minimum mastery criteria, largely due to conventional teacher-centered approaches and lack of engaging media. Knowledge Gap: Previous studies have examined the effectiveness of cooperative learning models such as Student Teams Achievement Division (STAD) or visual aids like puzzles separately, but few have integrated both strategies to address students’ conceptual and motivational difficulties in mathematics. Aims: This study aimed to improve mathematics learning processes and outcomes by combining the STAD model with puzzle media. Results: Conducted as Classroom Action Research in two cycles with 17 students, the findings indicated increased teacher performance (85% to 97%), student activeness (67% to 85%), and cognitive achievement (67% to 84%). Novelty: The research demonstrates the effectiveness of integrating STAD with puzzle media in mathematics learning within the Merdeka Curriculum, a combination not extensively studied in rural elementary contexts. Implications: This approach provides an innovative and practical strategy for fostering active, collaborative, and meaningful learning, offering a model that can be adapted for other mathematical topics and primary education settings.Highlight : STAD with puzzle media improved the learning process and student activeness. Teacher performance increased from good to very good between cycles. Student learning outcomes rose significantly from 67% to 84%.
