Abstract

Students often struggle to identify relevant analog problems when solving new tasks, highlighting the need for teachers to design simple analog problems that serve as scaffolding. This study aims to analyze prospective teachers’ analogical reasoning processes in simplifying complex geometry problems using the Analogical Reasoning in Mathematics (ARM) framework. This qualitative research involved 34 prospective mathematics teachers from a public university in Surabaya, Indonesia. Participants were selected through purposive sampling based on their academic performance and prior coursework in geometry and problem solving. Data were collected through task-based interviews, written work, and observations during problem-simplification activities. The collected data were analyzed thematically, guided by the components of the ARM framework. The results indicate that prospective teachers with varying ability levels employed different analogical reasoning strategies to simplify complex problems through ARM activities. High-ability prospective teachers identified a broader range of student difficulties and adapted the problems into two-step analog problems featuring variations in visual representations, number of circles, and geometric shapes. Conversely, low-ability prospective teachers focused on difficulties related to verbal representation and the need for concrete numerical information, adapting the problems into single, highly simplified analog problems with specific images and numbers. Overall, prospective teachers actively utilized analogical reasoning to design analog problems that addressed student difficulties. Differences in ability were associated with the complexity of adaptation strategies and the depth of difficulty identification, underscoring the importance of training prospective teachers to integrate both approaches to effectively support student understanding.

Abstract

This Community Service Program aims to improve the competency of high school mathematics teachers in Magetan Regency in developing questions based on Higher Order Thinking Skills (HOTS). The training is designed to provide a deep understanding of HOTS concepts, including cognitive levels C4 (analysis), C5 (evaluation), and C6 (creation), and to equip teachers to design contextual, relevant questions that meet students' needs. With this approach, teachers are expected to produce questions that not only assess students' basic abilities but also foster their critical, creative, and analytical thinking. The training will be conducted through several stages: HOTS concept socialization, a question development workshop, classroom simulations, and post-training mentoring. Teachers will be trained to develop question outlines, select engaging contextual stimuli, and develop HOTS-based questions in accordance with the Merdeka Curriculum and Minimum Competency Assessment (MCA) standards. Additionally, a questionnaire will be used to assess teachers' understanding of the training material. Participants found this activity highly beneficial in improving teacher competency, both in material delivery, question development, and knowledge of the latest curriculum.

Abstract

Purpose: This study aims to analyze and precisely describe the profile of students' contextual problem-solving skills differentiated by their initial mathematical proficiency levels. Design/methodology/approach: This descriptive qualitative study involved two purposefully selected students (one with high and one with low mathematical ability). Data were systematically gathered utilizing written diagnostic tests and in-depth interviews, structured around four fundamental problem-solving indicators. Findings: Both subjects successfully satisfied the four basic problem-solving indicators. Nevertheless, the high-ability student exhibited superior cognitive mastery, evidenced by significantly clearer articulated resolution strategies and meticulous mathematical justifications in both test responses and interviews compared to the low-ability peer. Practical implications: These findings compel mathematics educators to operationalize differentiated instructional strategies, systematically tailoring pedagogical interventions to students' baseline proficiencies to optimally cultivate their contextual problem-solving capabilities. Originality/value: This research provides a microscopic perspective into the qualitative disparities in cognitive articulation and procedural detail between students of varying abilities, particularly highlighting nuances that persist even when baseline problem-solving metrics are ostensibly met.   Purpose: Penelitian ini bertujuan untuk menganalisis dan mendeskripsikan secara spesifik profil kemampuan pemecahan masalah kontekstual siswa berdasarkan perbedaan tingkat kemampuan awal matematika. Design/methodology/approach: Studi kualitatif ini melibatkan dua siswa (satu berkemampuan matematika tinggi dan satu rendah) sebagai subjek penelitian. Data dikumpulkan melalui instrumen tes tertulis dan wawancara mendalam yang dievaluasi menggunakan empat indikator pemecahan masalah. Findings: Kedua subjek pada dasarnya mampu memenuhi keempat indikator pemecahan masalah. Namun, subjek berkemampuan tinggi menunjukkan tingkat penguasaan yang lebih superior, ditandai dengan artikulasi strategi dan justifikasi matematis yang jauh lebih jelas dan terperinci pada hasil tes maupun wawancara dibandingkan subjek berkemampuan rendah. Practical implications: Temuan ini mendorong guru matematika untuk merancang strategi pembelajaran berdiferensiasi yang menyesuaikan intervensi pedagogis dengan profil kemampuan awal siswa untuk mengoptimalkan keterampilan pemecahan masalah kontekstual secara individu. Originality/value: Kajian ini memberikan wawasan mikroskopis mengenai kesenjangan kualitas artikulasi dan detail proses kognitif antara siswa dengan kemampuan berbeda, meskipun keduanya secara teknis mencapai ambang batas indikator dasar pemecahan masalah.

Abstract

Klasifikasi bahasa merupakan salah satu tugas dasar dalam pemrosesan bahasa alami (Natural Language Processing/NLP) yang berfungsi untuk mendeteksi bahasa dari suatu teks. Tugas ini menjadi semakin penting seiring meningkatnya penggunaan aplikasi multilingual seperti chatbot, platform digital global, dan sistem moderasi konten. Penelitian ini mengimplementasikan FastText sebagai model klasifikasi untuk mengidentifikasi bahasa menggunakan dataset multilingual dari Kaggle. FastText dipilih karena kemampuannya dalam memanfaatkan karakter n-gram dan subword representation, sehingga tetap mampu memberikan prediksi yang presisi meskipun teks yang digunakan sangat pendek atau memiliki variasi penulisan. Proses penelitian meliputi tahapan preprocessing teks, konversi label ke format FastText, pelatihan model, pengujian, serta evaluasi menggunakan metrik akurasi, precision, recall, F1-score, dan confusion matrix. Hasil evaluasi menunjukkan bahwa model FastText mampu mencapai akurasi lebih dari 90% dengan waktu pelatihan yang ringkas dan efisien. Temuan ini menegaskan bahwa FastText merupakan solusi praktis dan ringan untuk kebutuhan deteksi bahasa otomatis dalam skala besar. Selain itu, penelitian ini memberikan gambaran mengenai bagaimana metode klasifikasi berbasis embedding seperti FastText dapat diterapkan pada dataset multilingual dengan struktur yang beragam. Implementasi FastText dalam proyek ini menunjukkan bahwa pendekatan yang sederhana namun efektif tetap mampu memberikan performa kompetitif untuk tugas-tugas dasar NLP, sehingga dapat dijadikan referensi bagi pengembangan sistem NLP lain yang memerlukan tahap deteksi bahasa sebagai bagian awal pemrosesan. Di samping hasil performa yang baik, penelitian ini juga menunjukkan bahwa proses implementasi FastText relatif mudah dilakukan, sehingga cocok digunakan baik oleh pemula maupun pengembang yang membutuhkan solusi cepat untuk klasifikasi bahasa. Pendekatan ini dapat menjadi dasar bagi pengembangan model NLP yang lebih kompleks dan mendalam di masa mendatang.

Abstract

This study investigates the individual and collaborative designs of context-based numeracy tasks developed by mathematics teachers employing three different contexts, namely, Islamic inheritance law, population census, and genetics. The tasks were designed at different levels of knowing, applying, and reasoning. The obtained data were analyzed using PISA’s contextual framework and Indonesia’s cognitive taxonomy to evaluate task solvability, context type, context level, and cognitive demand. The results show significant differences: most individual designs remained at the knowing level (88.23%), had first-order contexts (88.23%), and had 19.05% of tasks that could not be solved due to insufficient information. Collaborative designs eliminated all tasks that could not be solved, increased the number of reasoning-level tasks from 7.84% to 24.39%, and removed all zero-order context levels. Both preferred social settings (52%), but collaborative designs showed more integration. For example, context-based numeracy problems created individually ask students to determine the percentage of Generation Z. In contrast, group-created problems ask them to analyze the impact of demographics on planning. These findings demonstrate the importance of teacher collaboration in increasing the authenticity and complexity of learning activities. Systematic collaboration frameworks should be incorporated into teacher professional development programs.

Abstract

Forest and land fires in Pelalawan Regency, Riau Province, represent a persistent and multidimensional environmental governance challenge shaped not only by ecological factors, but also by land-use change dynamics, plantation expansion, and the complexity of cross-sectoral and multi-level policy networks. This study aims to examine the interrelationships among land cover change, hotspot dynamics, and the structural configuration of the forest and land fire control policy network in Pelalawan Regency. The research adopts an integrated approach combining spatial analysis and policy network analysis. Spatial analysis assesses land cover change and the distribution of fire hotspots for the 2000–2022 period using Terra and Aqua satellite data from the Moderate Resolution Imaging Spectroradiometer (MODIS) with a confidence level of ≥50%, overlaid with land cover data from the Ministry of Environment and Forestry. Subsequently, policy network analysis is conducted using a Social Network Analysis (SNA) approach applied to 53 regulatory instruments at the national, provincial, and regency levels, measuring degree centrality, betweenness centrality, closeness centrality, and eigenvector centrality. The findings indicate that hotspot surges prior to 2016 are strongly correlated with plantation expansion and weak policy implementation effectiveness, despite the presence of an extensive normative regulatory framework. Law No. 32/2009 is identified as the most central normative node within the policy network, while the strengthening of operational policies after 2016 has contributed significantly to the reduction of forest and land fire incidents. This study underscores that the effectiveness of forest and land fire control is determined not by regulatory proliferation, but by the integration of policy networks and cross-sectoral implementation capacity.
