Abstract

Abstrack Mathematics learning, particularly on solid geometry, still faces challenges in students’ conceptual understanding and engagement due to the dominance of conventional teaching approaches. This study aims to analyze the needs and design an e-book based on Problem Based Learning (PBL) as an alternative innovative teaching material. The method used is library research by reviewing relevant literature on mathematics education, PBL, and digital learning media. The e-book design refers to the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation, with this study focusing on the analysis and design stages. The results indicate that the e-book is systematically designed by integrating PBL, starting from problem orientation, investigation, to evaluation, and is supported by multimedia elements such as images, animations, and videos. This integration produces a contextual, interactive design that supports independent learning. Therefore, the contextually designed PBL-based e-book has the potential to serve as an effective learning medium to enhance students’ conceptual understanding and promote more active, interactive, and independent learning processes.

Abstract

This study aims to describe students’ strategies and creativity in solving mathematical literacy problems. Mathematical literacy requires students not only to understand mathematical concepts but also to select appropriate problem-solving strategies and apply creative thinking in various contexts. Therefore, understanding how students use strategies and demonstrate creativity in solving mathematical literacy problems becomes important. The research employed a qualitative descriptive method involving junior high school students who were categorized into high, medium, and low ability levels based on the results of a mathematical literacy problem-solving test. The main instruments were the researchers themselves, while the supporting instruments included a mathematical literacy test, interview guidelines, and validation sheets. Data were collected through two stages of testing and two stages of interviews, and triangulation was employed to ensure data validity. In addition, triangulation across methods and time was employed to enhance the validity of the data. The results showed that students demonstrated different strategies and levels of creativity in solving problems. Students in the high-ability category were able to understand problems well, choose appropriate strategies, and exhibit all indicators of creativity—fluency, flexibility, and novelty. Medium-ability students showed fluency and novelty or flexibility and novelty, while low-ability students generally did not meet any creativity indicators due to difficulties in understanding the problems and selecting proper strategies.

Abstract

Kajian tentang integrasi etnomatematika dan Augmented Reality (AR) dalam pembelajaran geometri belum banyak memusatkan perhatian pada proses representasi visual matematis siswa secara mendalam. Penelitian ini bertujuan mendeskripsikan representasi visual matematis siswa kelas VIII dalam pembelajaran matematika berbasis etnomatematika berbantuan Augmented Reality pada materi bangun ruang sisi datar. Penelitian menggunakan pendekatan kualitatif dengan jenis studi kasus yang dilaksanakan di SMP Negeri 1 Kairatu, Kabupaten Seram Bagian Barat, Maluku. Subjek penelitian terdiri atas tiga siswa yang mewakili kategori representasi visual reproduktif, transisional, dan konseptual. Data dikumpulkan melalui observasi pembelajaran, LKPD berbasis AR, dokumentasi hasil kerja siswa, dan wawancara semi-terstruktur. Objek budaya Maluku yang digunakan meliputi Masjid Tua Wapauwe, Gereja Tua Imanuel, Rumah Tua Lating Nustapy, dan Benteng Amsterdam. Hasil penelitian menunjukkan bahwa representasi visual matematis siswa tahapdikategorikan dalam tiga kategori representasi visual. Pada kategori reproduktif, siswa menyalin bentuk visual objek budaya tanpa menghubungkannya dengan konsep bangun ruang. Pada kategori transisional, siswa mulai mendekomposisi objek ke dalam bentuk balok, prisma, atau limas, namun masih mengalami kesulitan pada jaring-jaring dan hubungan antarsisi. Pada kategori konseptual, siswa mampu mengubah tampilan AR menjadi sketsa, jaring-jaring, tabel unsur, rumus, dan penjelasan matematis yang bermakna. AR efektif membantu visualisasi, tetapi pemahaman konseptual tetap memerlukan scaffolding dan refleksi terarah dari guru.

Abstract

This study aims to analyze learning needs and design Deep Learning-based teaching materials on the topic of Systems of Linear Equations in Two Variables (SLETV). The study employed a Research and Development (R&D) approach using the ADDIE model, limited to the analysis and design stages. The data sources were obtained through literature studies, including scientific journals, reference books, and previous studies related to Deep Learning, mathematics teaching materials, and SLETV topics. The data analysis technique used was descriptive qualitative analysis. The results showed that SLETV learning is still predominantly procedure-oriented, causing students difficulties in understanding concepts, modeling mathematical problems, and solving contextual problems. Based on these findings, Deep Learning-based teaching materials were designed by integrating the dimensions of meaningful, mindful, and joyful learning through contextual problem presentation, concept exploration activities, discussions, reflections, and problem-solving exercises. The teaching materials were systematically designed to include learning objectives, concept maps, learning materials, student activities, exercises, reflections, and evaluations. These teaching materials are expected to support more meaningful mathematics learning and help students understand SLETV concepts more deeply.

Abstract

Penelitian ini bertujuan untuk mengeksplorasi kemampuan berpikir geometri siswa SD dalam menyelesaikan masalah matematika melalui media pembelajaran berbasis Augmented Reality (AR) berdasarkan teori Van Hiele. Penelitian menggunakan pendekatan kuantitatif dengan desain penelitian eksplorasi terhadap 32 siswa kelas VI MIT Daarunnaim Wayame. Hasil penelitian menunjukkan bahwa kemampuan berpikir geometri siswa terkonsentrasi pada level visualisasi (28,13%), analisis (28,13%), dan deduksi informal (31,25%), dengan sedikit siswa mencapai level deduksi formal (9,38%) dan rigor (3,13%). Implementasi media pembelajaran berbasis AR efektif meningkatkan kemampuan berpikir geometri siswa pada level 0 hingga level 3 (p < 0,05), dengan peningkatan terbesar pada level deduksi informal. Terdapat korelasi positif signifikan antara kualitas interaksi dengan media AR dan peningkatan kemampuan berpikir geometri, dengan tingkat keterlibatan interaktif sebagai faktor terkuat (r = 0,826). Analisis klaster mengidentifikasi tiga kelompok siswa berdasarkan respons terhadap pembelajaran berbasis AR yang berkorelasi dengan tingkat peningkatan kemampuan mereka. Penelitian ini menyimpulkan bahwa media pembelajaran berbasis AR berpotensi signifikan mengembangkan kemampuan berpikir geometri siswa SD sesuai teori Van Hiele, namun implementasinya perlu mempertimbangkan aspek pedagogis, teknologis, dan karakteristik individual siswa.

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.

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

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.
