Abstract

This study was motivated by students’ low conceptual understanding of mathematics, as indicated by the results of the Programme for International Student Assessment (PISA), as well as mathematics instruction that remains abstract and lacks context. Therefore, the development of instructional materials capable of linking mathematical concepts to real-world situations requires innovation. The objective of this study is to create STEM-based instructional materials that meet valid, practical, and effective standards by using the Realistic Mathematics Education (RME) approach for the topic of curved-edged three-dimensional shapes in Grade 10 MIPA at SMA in Bone. This study is a research and development (R&D) project using the ADDIE model, which includes the analysis, design, development, implementation, and evaluation stages. The research subjects consisted of subject matter experts, design experts, teachers, and 10th-grade students. An abstract is often presented separately from the article, so it must be able to stand-alone. Data collection techniques included interviews, questionnaires, and achievement tests. The data obtained were analyzed using descriptive statistical techniques to assess the validity, practicality, and effectiveness of the developed instructional materials. This study is expected to produce STEM-based instructional materials that can enhance students’ understanding of geometric concepts through contextual and meaningful learning that utilizes local culture as a learning resource. Therefore, the developed instructional materials can serve as an innovation.

Abstract

The low level of students’ conceptual understanding in plane geometry is caused by learning practices that are still oriented toward memorizing formulas, thus requiring innovative learning media that can support meaningful understanding. This study aims to analyze the needs and design a contextual-based interactive e-book for plane geometry material for eighth-grade students in junior high school. This research employs a conceptual design approach using the Research and Development (R&D) method, limited to the stages of needs analysis and product design. Data were obtained through a literature review related to digital learning media, interactive e-books, and contextual approaches, and were analyzed using descriptive qualitative techniques. The results indicate that the interactive e-book is designed with a systematic structure, including concept maps, gradual material presentation, and the integration of interactive features such as animations, videos, and exercises. The contextual approach embedded in the e-book enables students to understand mathematical concepts through their connection to real-life situations. Therefore, the contextual-based interactive e-book contributes as a potential learning medium to improve students’ conceptual understanding and to support more active, interactive, and independent learning.

Abstract

Penelitian ini bertujuan mendeskripsikan kesalahan mahasiswa dalam menerapkan algoritma Metode Posisi Palsu menggunakan bahasa pemrograman PHP melalui pendekatan Computational Thinking–Error Analysis Framework (CT–EAF). Desain penelitian yang digunakan adalah deskriptif kualitatif dengan menganalisis tugas akhir mahasiswa yang terdiri atas dokumentasi algoritma dan kode yang dapat dieksekusi. Analisis meliputi reduksi data, klasifikasi kesalahan, serta interpretasi berdasarkan dimensi computational thinking dan kategori kesalahan matematika. Temuan penelitian menunjukkan bahwa mahasiswa mengalami berbagai kesulitan dalam menerjemahkan konsep matematika ke dalam struktur komputasi dan dalam mengevaluasi ketepatan hasil iterasi. Sebagian besar kesalahan terkait dengan tantangan dalam mengabstraksikan rumus matematika Metode Posisi Palsu ke dalam logika program, serta keterbatasan refleksi dan debugging terhadap hasil komputasi. Kesalahan dalam abstraksi terutama meliputi penggunaan operator yang tidak tepat, kesalahan tanda kurung, atau penerjemahan rumus Metode Posisi Palsu yang keliru, sementara kesalahan evaluasi berkaitan dengan pengabaian kriteria konvergensi numerik ∣f(c)∣ < ε atau |Δc| < ε. Integrasi CT–EAF memberikan perspektif yang komprehensif mengenai hubungan antara proses berpikir algoritmik mahasiswa dan jenis kesalahan konseptual serta prosedural yang mereka lakukan. Penelitian ini menegaskan pentingnya penguatan computational thinking dan literasi algoritmik dalam pembelajaran metode numerik. Pendekatan CT–EAF berfungsi sebagai kerangka yang efektif untuk memandu mahasiswa menghubungkan konsep matematika dengan logika komputasi, sehingga mendorong proses pembelajaran yang menekankan pemahaman konseptual dan penalaran algoritmik, bukan sekadar menghasilkan output komputasional.

Abstract

Discrete Mathematics learning at the university level requires high-level reasoning skills and deep conceptual understanding, particularly in the topic of recursive relations. However, in instructional practice, students still experience various learning difficulties that affect the quality of their understanding. This study aims to identify students’ learning obstacles in recursive relations as a preliminary study within the framework of Didactical Design Research (DDR). A qualitative approach was employed by analyzing students’ responses to true–false items accompanied by written justifications administered in a final examination. The data were analyzed to identify learning obstacles based on ontogenic and epistemological perspectives. The findings indicate that students experience learning obstacles characterized by the inappropriate use of prior mathematical knowledge, limited ability to provide conceptual justifications, and a tendency toward procedural reasoning in contexts that require deeper conceptual analysis. These results suggest that students’ difficulties in recursive relations cannot be separated from the didactical situations framing the learning process. This preliminary study provides a foundation for the development of didactical designs in subsequent research, with the conceptual integration of the Case Method to reconstruct more meaningful learning situations in Discrete Mathematics.

Abstract

Mathematical literacy is an essential 21st-century competency that plays a crucial role in supporting individuals’ abilities to reason, solve problems, and make data-driven decisions across various real-life contexts. Along with the growing global attention to mathematical literacy, particularly through international assessments such as the PISA, research in this field has expanded rapidly in both quantity and scope. However, findings reported across different journals remain fragmented, highlighting the need for a systematic mapping to obtain a comprehensive overview of research trends, distributions, and future directions in mathematical literacy studies. This study aims to examine the relevance of mathematical literacy as a focus for future research, identify research trends and distributions, and explore the theoretical and practical implications for subsequent studies. The research employed a Systematic Literature Review combined with bibliometric analysis of 268 Scopus-indexed articles published up to December 15, 2025. The literature selection process followed the PRISMA framework, while bibliometric mapping and visualization were conducted using VOSviewer software. The results indicate a significant upward trend in publications since 2016, peaking in the 2023–2025 period, suggesting that mathematical literacy remains a highly relevant and prominent topic in mathematics education research. Geographically, Indonesia emerged as the largest contributor and a central hub in international research collaboration networks. Keyword co-occurrence analysis revealed the dominance of themes related to mathematical literacy, students, gender differences, psychology, PISA, and controlled studies. Nevertheless, notable research gaps persist, particularly regarding the integration of digital learning media. These findings provide important theoretical and practical foundations for the advancement of future research and instructional innovations in mathematical literacy.
