Abstract

Real Analysis is often a gatekeeper course in mathematics education, marking the difficult transition from computational calculus to formal axiomatic proof. Prospective mathematics teachers frequently struggle to construct rigorous proofs, even for fundamental properties. This study employs Newman's Error Analysis (NEA) to analyze the epistemological obstacles underlying these struggles. This descriptive qualitative case study involved 15 fifth-semester undergraduates at Universitas Muhammadiyah Makassar who completed a diagnostic proof test on field properties. Analysis of student work revealed that none made errors at the 'Reading' stage. Instead, errors clustered at higher cognitive stages: 3 students exhibited Comprehension errors, 5 made Transformation errors, 4 showed Process Skills errors, and 3 made Encoding errors. From this cohort, four subjects, each exemplifying one of these non-reading error types, were selected for in-depth semi-structured interviews. The findings indicate a hierarchical breakdown in proof construction specifically for the theorem: "If a ≠ 0 and a ∈ ℝ, prove that  ≠ 0." Students either failed to translate verbal understanding into explicit premises (Comprehension), could not operationalize an indirect proof strategy (Transformation), neglected to justify algebraic steps with axioms (Process Skills), or omitted formal concluding statements (Encoding). The study concludes that errors often perceived as "carelessness" can be symptoms of deeper epistemological obstacles, such as viewing proof as a computational ritual rather than a formal, communicative argument. These findings underscore the need for explicit instruction on proof mechanics and structure, even when students possess correct mathematical intuition.

Abstract

The material of Three-Variable Linear Equation Systems (TVLES) possesses high complexity that potentially causes excessive cognitive load for students. This research is a preliminary study aimed at analyzing students' learning difficulties and mapping the requirements for developing digital learning media to reduce this cognitive load. Specifically, this study addresses two research questions: (1) which TVLES sub-skills are the most difficult and what types of errors dominate? and (2) what media feature preferences are prioritized by students and teachers? The research method employed is a descriptive quantitative-qualitative (mixed-methods) approach to provide a comprehensive overview of the subjects' conditions. The research subjects consisted of 24 tenth-grade students at SMA Negeri 13 Gowa who had completed the TVLES material in the 2024/2025 academic year. Data collection techniques utilized source triangulation, including student needs analysis questionnaires, grade document analysis, in-depth interviews, and student work error analysis using conceptual, procedural, and computational coding frameworks. The results indicated low student learning outcomes, with a class average of 68.96 and a classical mastery rate of only 33.3%. Identified difficulties were consistent with indicators of cognitive overload, particularly the inability to model word problems (88%), indicating excessive information load on working memory. Based on preference analysis, 95.8% of students stated the necessity of developing Google Sites-based media containing step-by-step explanatory videos. The research concludes that the identified design requirements suggest the development of Google Sites as a strategic direction with the potential to reduce extraneous cognitive load and facilitate independent learning.
MENINGKATKAN HASIL BELAJAR MATEMATIKA MATERI OPERASI HITUNG PERKALIAN SISWA KELAS III UPT SDN 163 PINRANG MELALUI PENERAPAN MEDIA MULTIPLAY CARDS Nur Handayani Ismail; Nasrun Nasrun; Ma’rup Ma’rup

Abstract

Penelitian ini dilatarbelakangi oleh rendahnya hasil belajar matematika siswa kelas III UPT SDN 163 Pinrang pada materi operasi hitung perkalian. Permasalahan tersebut ditunjukkan oleh rendahnya partisipasi siswa dalam proses pembelajaran, kurangnya kepercayaan diri, kecenderungan bergantung pada teman yang dianggap lebih mampu, serta hasil belajar yang belum mencapai Kriteria Ketercapaian Tujuan Pembelajaran (KKTP). Penelitian ini bertujuan untuk meningkatkan hasil belajar matematika siswa pada materi operasi hitung perkalian melalui penerapan media Multiplay Cards. Penelitian ini menggunakan metode Penelitian Tindakan Kelas (PTK) yang dilaksanakan dalam dua siklus, dengan setiap siklus terdiri atas empat pertemuan. Setiap siklus meliputi tahap perencanaan, pelaksanaan tindakan, observasi, dan refleksi. Subjek penelitian adalah 19 siswa kelas III UPT SDN 163 Pinrang tahun ajaran 2025/2026 yang terdiri atas 12 siswa laki-laki dan 7 siswa perempuan. Hasil penelitian menunjukkan bahwa penerapan media Multiplay Cards mampu meningkatkan hasil belajar matematika siswa. Penggunaan media berbasis permainan kartu menjadikan pembelajaran lebih menarik, interaktif, serta meningkatkan keaktifan dan motivasi belajar siswa. Nilai rata-rata hasil belajar siswa meningkat dari 56% pada siklus I menjadi 76% pada siklus II, sedangkan ketuntasan belajar klasikal meningkat dari 21% menjadi 79%. Dengan demikian, penerapan media Multiplay Cards efektif dalam meningkatkan hasil belajar matematika siswa pada materi operasi hitung perkalian di kelas III UPT SDN 163 Pinrang.
