Abstract

This study presents a systematic literature review analyzing the validity and practicality of GeoGebra-supported mathematics learning modules. The purpose is to evaluate the scientific quality and classroom feasibility of these modules based on empirical evidence from published research between 2013 and 2023. A total of 27 studies were synthesized using PRISMA guidelines to assess content, construct, and instructional design validity, as well as ease of use, time efficiency, and user response. Findings indicate that most modules demonstrate high content validity through expert validation and curriculum alignment, and are perceived as practical and engaging by teachers and students. However, gaps exist in empirical validation of learning constructs and in the integration of cognitive load principles within instructional design. Challenges such as extended implementation time, technical barriers, and insufficient teacher training affect practicality in real classroom settings. The study concludes that while GeoGebra-supported modules hold strong potential for enhancing mathematics learning, their effectiveness depends on pedagogical soundness, systematic development, and contextual support. Standardized evaluation frameworks and improved teacher readiness are recommended for sustainable implementation.

Abstract

This study develops and validates a Hypothetical Learning Trajectory (HLT) integrating everyday life science contexts within Realistic Mathematics Education (RME) framework for teaching social arithmetic to seventh-grade students. Through design research methodology involving three students with varying mathematical abilities, the research examined how contextually rich learning activities scaffold students' progression from informal to formal mathematical reasoning. Results demonstrated significant improvements in conceptual understanding across all ability levels, with most substantial gains observed among lower-ability students (143.8% improvement). Qualitative analysis revealed students' transformation from procedural memorization to conceptual reasoning, with contextual barriers rather than cognitive limitations identified as primary impediments to mathematical understanding. The HLT successfully facilitated students' development of meaningful connections between mathematical procedures and real-world applications, particularly in profit-loss scenarios and taxation calculations. These findings indicate that RME-based contextual integration creates effective pathways to conceptual mastery, offering inclusive learning opportunities that address persistent gaps between classroom mathematics and practical application. The research contributes to both theoretical understanding of mathematics learning trajectories and practical instructional design for meaningful mathematics education.

Abstract

This quasi-experimental study examined the effect of the Project, Activity, Cooperative Learning, and Exercise (PACE) model on eighth-grade students' mathematical communication ability in solid geometry. Forty students from SMPN 6 Model Kota Sungai Penuh were assigned to an experimental group (PACE model) and a control group (conventional instruction). Both groups received six learning sessions on cubes and cuboids, followed by a six-item essay test assessing three communication indicators: written text, drawing, and mathematical expressions. Data analysis using independent samples t-test revealed the experimental group achieved a significantly higher mean score (81.25, high category) compared to the control group (73.125, moderate category); t(38) = 2.899, p = 0.006. The rejection of the null hypothesis confirmed that PACE implementation positively influenced students' ability to express mathematical ideas through verbal explanations, accurate visual representations, and appropriate symbolic notations. The model's project-based and collaborative components effectively scaffolded students' articulation of geometric concepts, demonstrating its pedagogical value for enhancing mathematical discourse in Indonesian lower secondary classrooms.

Abstract

This study aimed to develop and evaluate a Two Stay Two Stray (TSTS)-integrated digital flipbook electronic worksheet (E-LKPD) designed to enhance mathematical problem-solving abilities among eighth-grade students. Employing the Plomp research and development model, the product underwent systematic expert validation, iterative usability testing, and classroom-based field evaluation. Results indicated that both the teaching module and E-LKPD achieved "Very Valid" status, with mean validity scores of 3.47 and 3.54 respectively across content, instructional design, graphics, and language dimensions. Practicality assessments yielded "Very Practical" ratings: 90% for the teaching module and 84.26% for the E-LKPD during field testing. Effectiveness was demonstrated by 80% of students achieving mastery on a mathematical problem-solving assessment, surpassing the predefined 65% success threshold. These findings confirm that integrating the structured TSTS cooperative learning protocol within an interactive digital flipbook format can effectively support the development of mathematical problem-solving competencies. The developed product offers a scalable, curriculum-aligned instructional resource that bridges cooperative pedagogy with technology-enhanced learning.
