This study aims to analyse students' mathematical representation understanding on matrix material through the integration of real context-based technology. The problem raised in this research is the low ability of students in connecting matrix concepts with real-life situations. To answer these problems, this research used a descriptive qualitative approach with a case study design. The research subjects involved 29 grade XI students at SMK Negeri 1 Sekayu, who were grouped into seven groups. The sampling technique was purposive, while data were collected through tests and questionnaires. The data were analysed descriptively to identify students' mathematical representation patterns, including pictorial, symbolic and verbal representations. The results showed that the integration of Google Maps in matrix learning strengthened students' conceptual understanding through real spatial visualisation. This approach significantly improves students' ability to represent mathematical concepts, as well as encourages motivation, engagement and collaboration during the learning process. In addition, the findings underline the relevance of the real context-based approach in Indonesian Realistic Mathematics Education (PMRI), which makes learning more applicable and meaningful. The conclusion of this study is that the integration of Google Maps has a positive influence on students' mathematical representation skills, especially on matrix material. For future research, it is recommended to explore the application of similar technology in other mathematics materials and analyse its effect on students' problem solving.   Translated with DeepL.com (free version) Penelitian ini bertujuan untuk menganalisis pemahaman representasi matematis siswa pada materi matriks melalui integrasi teknologi berbasis konteks nyata.

Abstract

Effective mathematical communication is essential for developing conceptual understanding and applying mathematics in real-life contexts. However, empirical studies consistently report that students' mathematical communication skills remain insufficiently developed, highlighting a critical gap in instructional practices that effectively foster these competencies. The Realistic Mathematics Education (RME) approach, grounded in six core principles—reality, levels, intertwinement, activity, interactivity, and guidance—has demonstrated promise in promoting meaningful and contextualized learning. Yet, there is limited empirical research that systematically investigates how these principles specifically support the enhancement of students’ mathematical communication. This study addresses that gap by examining how the application of RME principles contributes to the development of communication skills in junior high school mathematics classrooms. Utilizing a qualitative research design, data were gathered from nine schools across three districts through focus group discussions, lesson plan analysis, and classroom observations. Participants included RME experts, education policymakers, school principals, and mathematics teachers. Thematic analysis was conducted to identify how the six RME principles are operationalized in practice and how they align with indicators of students’ mathematical communication. The findings reveal that each principle plays a distinct yet interconnected role in supporting communication—particularly through meaningful contexts, dialogic interactions, and structured teacher guidance. The study offers empirical support for the broader adoption of RME and highlights its potential to increase teacher motivation and instructional quality. It further underscores the importance of sustained professional development—such as mentoring and lesson study—in enhancing teachers' capacity to implement RME effectively. Future research should focus on developing RME-based instructional materials and digital tools, including GeoGebra-integrated worksheets and context-rich problem sets, to amplify its impact within mathematics education in Indonesia.

Abstract

Statistical literacy has emerged as a central competence in mathematics education, particularly for prospective teachers who must be able to interpret, analyze, and critically evaluate data in a world increasingly shaped by information and statistics. However, previous research shows that many prospective teachers continue to struggle with developing statistical literacy, especially in connecting abstract concepts to meaningful contexts. This gap highlights the need for instructional designs that not only strengthen statistical reasoning but also draw on culturally embedded practices to enhance relevance and engagement. Addressing this challenge, the present study develops a Local Instructional Theory (LIT) that supports prospective teachers’ statistical literacy through the integration of local cultural contexts in South Sumatra, designed within the framework of Realistic Mathematics Education (RME) as adapted in Indonesia, namely Pendidikan Matematika Realistik Indonesia (PMRI). Employing a design research methodology, the study was conducted in three phases: a preliminary investigation, a design experiment (pilot and teaching experiment), and a retrospective analysis. The resulting LIT was structured around three context-based learning trajectories, each targeting a key dimension of statistical literacy: data visualization, data interpretation, and critical evaluation. Instructional activities were grounded in authentic cultural contexts—such as Pempek demand during Ramadan, the Bekarang Iwak fishing tradition, and coffee productivity in Pagar Alam—which were used to bridge statistical concepts with learners lived experiences. Findings from the teaching experiments indicate that prospective teachers demonstrated notable shifts from procedural to conceptual reasoning and from descriptive analysis to reflective critique. Participants also showed improved ability to select appropriate graphical representations, interpret contextual data, and critically assess the credibility and sufficiency of statistical information. These outcomes underscore the potential of culturally relevant instructional design to foster holistic statistical literacy. The study contributes both theoretically and practically by offering a validated model for integrating cultural contexts into mathematics education, thereby enriching prospective teachers’ curriculum and providing a replicable approach for diverse educational settings.
