Abstract

This research aims to determine the effect of the Problem-Based Learning (PBL) model with the Realistic Mathematics Education (RME) approach on students' mathematical communication skills. This research approach uses a quantitative approach with an experimental research type, a quasi-experimental type with a pretest-posttest control design. The population in this study was 107 MTs Guppi Buntu Barana students. The research sample consisted of 36 students. The sampling technique uses Cluster Random Sampling. Tests and observations were carried out for data collection. The research instruments used in this research were mathematical communication ability test questions and observation sheets. Data analysis techniques use descriptive statistical analysis and inferential statistical analysis. The results of this research show that the average mathematical communication ability of students in classes that do not use the PBL model with the RME approach from pretest to post-test increased from 34.50 to 81.56, with an increase of 47.06. The mathematical communication skills of students in classes that use the PBL model with the RME approach obtained an average score from pretest to posttest that increased from 40.39 to 89.72, with an increase of 49.33. So, the PBL model with the RME approach has a significant influence on students' mathematical communication skills.

Abstract

Pembelajaran matematika di Sekolah Dasar masih menghadapi tantangan serius, terutama dalam mengakomodasi perbedaan kemampuan belajar siswa, keterbatasan waktu guru, serta tuntutan adaptasi terhadap perkembangan teknologi digital. Kondisi ini menuntut adanya upaya pemberdayaan guru yang tidak hanya berfokus pada penguasaan materi, tetapi juga pada penguatan kapasitas pedagogis melalui pemanfaatan teknologi yang relevan dan kontekstual. Artikel ini bertujuan untuk mengkaji dan merumuskan pendekatan penguatan kapasitas guru Sekolah Dasar dalam pembelajaran matematika melalui integrasi Deep Learning sebagai pendekatan pembelajaran adaptif di era digital. Metode yang digunakan adalah studi kepustakaan dengan pendekatan deskriptif kualitatif, melalui penelaahan dan sintesis literatur ilmiah yang relevan terkait Deep Learning, pendidikan matematika dasar, dan pemberdayaan guru. Hasil kajian menunjukkan bahwa integrasi Deep Learning berpotensi mendukung guru dalam merancang pembelajaran matematika yang lebih terpersonalisasi, mendeteksi kesulitan belajar siswa secara dini, serta mengurangi beban administratif melalui pemanfaatan sistem penilaian otomatis. Temuan ini menegaskan bahwa Deep Learning tidak berfungsi sebagai pengganti peran guru, melainkan sebagai alat pendukung yang memperkuat pengambilan keputusan pedagogis berbasis data. Dalam konteks pengabdian kepada masyarakat, pendekatan ini dapat diimplementasikan melalui pelatihan literasi data, pendampingan pemanfaatan platform pembelajaran adaptif, serta penerapan model pembelajaran hibrida yang menempatkan guru sebagai fasilitator utama. Kajian ini diharapkan dapat menjadi rujukan konseptual bagi program pengabdian yang berfokus pada peningkatan kualitas pembelajaran matematika di Sekolah Dasar secara berkelanjutan dan responsif terhadap perkembangan teknologi.

Abstract

This study aims to develop a Linktree-based learning media for the Introduction to Education course that is valid and practical. This research employed a Research and Development (R&D) method using the ADDIE model, which consists of Analyze, Design, Develop, Implement, and Evaluate stages. In the analysis phase, a need assessment was conducted to identify students’ needs for technology-based learning media. The results indicated that most students require learning media that are flexible, interactive, and accessible online. The developed product is a digital Linktree platform containing various learning features such as brainstorming, videos, materials, motivation, and quizzes. The validation results showed that the media achieved a score of 93.25% (very valid), while the material validation reached 94% (very valid). The practicality test results showed 96.3% in the small group test and 96.2% in the field test, both categorized as very practical. Therefore, the developed Linktree-based learning media is feasible to be used in the learning process.

Abstract

This descriptive qualitative study maps the locations and etiological factors of mathematical errors among eighth-grade students in solving Linear Equations in Two Variables (LETV), analyzed through cognitive style typologies. Using purposive sampling, five representative subjects two Field Independent (FI) and three Field Dependent (FD) students—were selected. Data triangulation involved the Group Embedded Figures Test (GEFT), a problem-solving test, and clinical interviews, analyzed through an interactive model of reduction, display, and verification. Results indicate that FI students commit conceptual errors due to lack of thoroughness, principle errors from personalized methods, and procedural errors from unsystematic approaches. Conversely, FD students exhibit conceptual errors from misunderstanding prerequisites, principle errors in mathematical modeling, and procedural errors due to inappropriate methods and low arithmetic accuracy. The study emphasizes the necessity of instructional differentiation: teachers should provide systematization exercises for FI students to minimize carelessness and intensive scaffolding for FD students to improve their transformation of word problems into formal models. This approach aims to reduce cognitive barriers by addressing specific learning characteristics.
