Abstract

Penelitian ini bertujuan menjelaskan ketepatan soal yang digunakan untuk mengukur kemampuan CE matematis materi aljabar, mengetahui kemampuan CE matematis siswa yang diidentifikasi dari soal-soal yang diberikan dan menghasilkan soal tes CE yang efektif digunakan dalam proses pembelajaran. Metode penelitian pengembangan yang digunakan adalah model pengembangan 4-D (define, design, develop, diseminasi). Analisis data yang digunakan yaitu analisis kualitatif dan analisis kuantitatif. Analisis kualitatif dilakukan melalui analisis front-end, analisis peserta didik, dan one-to-one. Analisis kuantitatif dilakukan melalui uji validitas dan reliabilitas. Dengan analisis tersebut diperoleh hasil 10 instrumen tes yang dikembangkan untuk mengukur kemampuan CE siswa SMP pada materi PLSV memenuhi indikator akurasi dengan rata-rata 3,6 , validitas 0,42 dan  reliabilitas 0,59. Kemampuan CE mata pelajaran aljabar siswa SMP berada pada kriteria sangat rendah yaitu 3,06 (skala 0 – 10) dengan nilai terendah 0 dan tertinggi 10. Hasil penelitian menunjukan bahwa materi aljabar dengan penggunaan soal counter-example matematis memenuhi tingkat efektif dalam proses pembelajaran.

Abstract

Mathematical representation ability is an essential skill for students to understand mathematical concepts. Many studies have been conducted regarding this ability, but it is necessary to map existing research to provide a clearer picture of future research topics. This study aims to provide a bibliometric review of trends using mathematical representation skills in mathematics teaching research. The method in this study is bibliometric analysis, which aims to analyze and classify bibliographic material by presenting representative summaries of the literature in the Scopus database. The search was carried out using the keyword "mathematical representation" and selecting "article title" in the search menu in the Scopus.com database. Perish or Publish (PoP) software analyzes the author's name, number of document citations, document title, year of publication, document source, publisher, and document type. The results showed 99 publications and 357 citations related to mathematical representations, where the number of publications and citations fluctuated. The application of learning models and approaches, computer media, and analysis of mathematical representations is a research trend related to this variable. Therefore, paying attention to mathematical representations in learning mathematics and using effective strategies to improve students' mathematical representation abilities is essential. The findings of this study indicate the need to develop syntax and learning media based on mathematical representations to strengthen students' mathematical abilities.

Abstract

Background: Mathematical conceptual understanding remains a key issue in junior high school education. Innovation in learning media, such as digital tools, is needed to support effective learning. One promising approach is integrating Problem-Based Learning (PBL) with interactive digital media like E-flipbooks to enhance students’ engagement and comprehension in mathematics.Aim: This study aimed to develop a Problem-Based Learning-based E-flipbook that is valid, practical, and effective in improving students' mathematical concept understanding.Method: This research employed a Research and Development (R&D) design utilizing the ADDIE development model. The study participants were seventh-grade students from one of the public junior high schools located in the Batanghari Nuban sub-district during the 2024/2025 academic year. Data were collected through interviews, questionnaires, and mathematical concept comprehension tests. Data analysis involved expert validation, practicality indices, a proportion test, and a t-test.Results: The e-flipbook received high validity ratings from material experts (0.87) and media experts (0.90). Teacher and student responses indicated high practicality, with indices of 0.81 and 0.86, respectively. Additionally, over 60% of students demonstrated good understanding of mathematical concepts. The N-Gain and hypothesis test results showed a significant improvement in the experimental group compared to the control group.Conclusion: The e-flipbook developed through the problem-based learning approach was proven to be valid based on expert judgment, practical according to user responses, and effective in enhancing students’ mathematical concept understanding. These findings indicate that the integration of digital media and problem-based strategies can meaningfully support student learning. The product serves not only as a teaching aid but also as a tool to foster student engagement and active problem-solving. Therefore, this e-flipbook has the potential to be adopted as an innovative instructional resource in mathematics classrooms.
