Abstract

Minimum competency assessment is a basic competency that all students need to be able to develop their own abilities and play an active role in society in positive activities. Minimum competency assessment aims to measure students' cognitive learning outcomes which include reading literacy and numeracy competencies. This study aims to determine the types of errors made by students in solving algebraic domain numeracy problems based on the kastolan theory, namely: (1) conceptual errors, (2) procedural errors, (3) technical errors. The research that has been conducted is a qualitative descriptive study with a research instrument of three AKM type algebra essay questions on 26 class VIII 3 students at SMP N 1 Tambusai. The results obtained based on the results of student answer sheets include: (1) conceptual errors of 30.76%, procedural errors of 38.46%, and technical errors of 32.05%. It can be concluded that the mistakes that students often make are procedural errors. The results of this study provide an overview of the various errors made by students in solving algebraic domain AKM problems, so that they can determine follow-up actions so that students' numeracy skills become better.

Abstract

Kelompok usaha pengrajin gula aren di desa Desa Rambah Tengah Hulu merupakan pengrajin gula aren skala rumah tangga yang memproduksi gula aren secara tradisional. Teknologi yang digunakan berasal dari teknologi turun temurun termasuk proses pengemasan produk dan belum memiliki label, PIRT, dan Nomor Izin Berusaha. Saat ini produk gula aren yang dihasilkan para pengrajin juga masih dalam satu bentuk produk saja yaitu gula aren berbentuk balok. Berdasarkan informasi dari pengrajin bahwa mereka belum memahami tentang cara membuat produk hasil gula aren selain dari gula aren cetak/balok, artinya para pengrajin memiliki keterbatasan pengetahuan tentang potensi pembuatan gula aren menjadi produk lainnya, misalkan gula semut. Untuk meningkatkan pendapatan para pengrajin gula aren maka perlu ditingkatkan nilai tambah dari gula aren itu sendiri, sehingga tujuan dari pengabdian ini adalah perbaikan kemasan dan diversifikasi gula aren menjadi gula semut. Metode pelaksanaan kegiatan adalah pertama-tama pengrajin diberi penyuluhan tentang pentingnya NIB dan PIRT serta cara pengurusannya, selanjutnya para pengrajin diberi pelatihan tentang teknik pembuatan gula semut dan cara pengoperasian alatnya. Hasil dari pelaksanaan kegiatan ini yaitu Rata-rata pemahaman mitra tentang pentingnya NIB dan PIRT serta cara pengurusannya sudah mencapai 88%. Selanjutnya sebanyak 100% mitra sudah mengetahui tentang gula semut, cara pembuatan gula semut dan tahapan pembuatan gula semut. Mitra sudah memiliki alat pembuatan gula semut.

Abstract

Penelitian ini mengkaji novel Vegetarian karya Han Kang (2017) dengan menggunakan teori trauma, konsep postmemory Marianne Hirsch, serta konsep acting out dan working through oleh Dominick LaCapra. Penelitian ini merupakan penelitian kualitatif dengan pendekatan analisis teks melalui teknik close reading untuk menjawab (1) bagaimana trauma individu Yeong Hye dan mekanisme postmemory direpresentasikan dalam novel? dan (2) bagaimana dinamika acting out dan working through yang dialami oleh Yeong Hye. Hasil penelitian menunjukkan bahwa Yeong Hye mengalami trauma karena peristiwa pembunuhan anjing dan karena kekerasan fisik yang ia alami sejak kecil. Melalui konsep postmemory Marianne Hirsch, penceritaan langsung dan pengalaman afektif dari relasi ayah-anak menunjukkan mekanisme postmemory, di mana generasi kedua menyerap memori traumatis dari generasi pertama. Dalam novel ini, Yeong Hye merespons trauma yang ia alami tersebut dengan acting out, tetapi ia gagal dalam proses working through karena tidak adanya bantuan dari orang-orang terdekatnya hingga dia berakhir pada upaya penghancuran diri yang ekstrim.

Abstract

Twenty-first-century learning requires teachers, particularly prospective mathematics teachers, to possess strong mathematical literacy in order to guide students in understanding, applying, and interpreting mathematics in various real-life contexts. This study aimed to develop a valid and reliable mathematical literacy assessment instrument for prospective mathematics teachers by adopting the 4-D development model. The instrument focused on counting techniques and probability concepts, aligned with the AKM/IEA mathematical literacy cognitive levels of knowing, applying, and reasoning. The trial participants consisted of 64 undergraduate students enrolled in the mathematics education program at the second, third, and fourth-year levels. Content validity analysis using Aiken’s index indicated that all items were valid, with coefficients ranging from 0.80 to 0.95. Furthermore, construct validity testing through Confirmatory Factor Analysis (CFA) demonstrated adequate convergent validity, as indicated by an Average Variance Extracted (AVE) value of 0.581 and a composite reliability (ρc) value of 0.815. These findings indicate that the developed mathematical literacy assessment instrument meets validity and reliability criteria and is therefore suitable for use as an item bank in basic statistics courses or related subjects.

Abstract

Purpose – Students’ mathematical problem-solving ability remains low, particularly in the topic of relations and functions, as evidenced by frequent errors in solving problem-solving tasks. This study aims to identify and analyze the types of errors made by eighth-grade students in solving mathematical problem-solving questions on relations and functions using Newman’s Error Analysis. Methodology – This study employed a qualitative, descriptive research design. The participants were 29 Grade VIII.6 students from State Junior High School 1 Rambah. Data were collected through written problem-solving tests, semi-structured interviews, and documentation. The data were analyzed using Newman’s Error Analysis framework, which includes reading, comprehension, transformation, process skills, and encoding stages, following the steps of data reduction, data display, and conclusion drawing. Findings – The results indicated that the least frequent error was reading errors (36.2%), followed by comprehension errors (91.4%) and transformation errors (89.7%). The most frequent errors were process skills errors and encoding errors, each occurring in 100% of students’ responses. These findings suggest that students experience significant difficulties in executing mathematical procedures and expressing final answers correctly. Novelty – This study provides a detailed error profile of students’ problem-solving processes on relations and functions using Newman’s Error Analysis, highlighting critical stages where students consistently fail. Significance – The findings benefit mathematics teachers, curriculum developers, and researchers by providing insights into common student errors and supporting the development of instructional strategies that utilize students’ errors as learning resources to improve problem-solving ability.

Abstract

Purpose – Mathematical communication is essential in 21st-century mathematics learning because it enables students to represent, explain, and interpret ideas when solving contextual problems. This study aimed to describe seventh-grade students’ mathematical communication in solving algebraic word problems. Methodology – A qualitative descriptive design was used. Seventh-grade students at SMP Negeri 3 Rambah Hilir were purposively selected to represent high-, middle-, and low-achieving groups based on classroom performance and test results. Data were collected using an algebraic word-problem written test and semi-structured interviews. Analysis followed data reduction, data display, and conclusion drawing. Mathematical communication was examined using three indicators: (1) translating contexts/diagrams into mathematical language or models; (2) explaining mathematical ideas and relationships in writing; and (3) reading and interpreting written mathematical representations. Findings – Students’ mathematical communication was low. High-achieving students met all indicators, producing accurate representations and coherent written reasoning. Middle-achieving students generally met indicators (1) and (3), but their written explanations (indicator 2) were incomplete or unclear. Low-achieving students struggled across indicators, particularly in forming algebraic models and interpreting representations, leading to incorrect or incomplete solutions. The results highlight the need for explicit scaffolding of representation, written explanation, and interpretation in algebraic word-problem instruction. Novelty – This study offers an indicator-based profile of mathematical communication in algebraic word-problem solving across achievement levels using combined test and interview evidence. Significance – The findings support teachers and curriculum developers in designing learning activities and assessments that strengthen communication, representation, and reasoning in junior secondary algebra.
