The gap between the concept image and the concept definition will greatly affect a persons understanding of the concept. This study aims to reveal the gap between the concept image and the concept definition, and the causes of the emergence of the gap. The research subjects were 16 first-year mathematics students at one of the universities in Aceh, Indonesia. Data were obtained from the results of written tests and in-depth interviews. This qualitative research with a phenomenological study approach was analyzed descriptively. The results showed that the gap that occurs in the concept includes: the division of a non-zero number by zero yields infinity, the concept of dividing zero by zero is zero, the concept of dividing a number by zero is the same as the concept of the limit, e.g., , and the concept of the left-hand limit as means that the satisfied value of x is all negative numbers such that . The emergence of these concept images results from the subject's learning experience at school and a calculus course. This finding provides insights and considerations for educators to comprehensively introduce students to the concept of infinity to avoid misunderstandings in limit and next materials.

This study aims to explore the hidden mathematical concepts behind the rice farming activities of Pandanwangi Cianjur. The research method is qualitative research with an ethnographic approach. The research location is in Pandanwangi Cultural Village, Bunikasih Village, Warungkondang District, Cianjur Regency, West Java. Pandanwangi Cultural Village was deliberately built by the Cianjur Regency Government to further introduce pandanwangi rice, which is the superior local variety of Cianjur Regency. Pandawangi rice farmers' cultural activities contain mathematical concepts that arise when determining seed class, number of seeds, nursery preparation, final seed selection with salt solution, seeding in nurseries, nursery maintenance, preparation of planting land, planting, fertilization in planting areas, planting maintenance, harvest, and post-harvest. The findings of this study show that there are mathematical concepts in agricultural activities on geometric content, including determining points, lines, angles, the area of flat shapes, the similarity of flat shapes, and algebra, including comparisons, percentages, and social arithmetic. The results of the research can be used as a teaching module to facilitate learning for students in the school curriculum.

In Euclidean geometry, parallelism constitutes a foundational concept from which numerous geometric ideas are derived. Despite its fundamental role in geometry and its importance in developing deductive and logical reasoning, research on the concept of parallelism—particularly concerning students’ learning obstacles and corresponding didactical approaches—remains limited, especially in higher education contexts. This study investigates the construction of theorems related to parallelism conditions by examining learning obstacles and implementing a GeoGebra-based didactical design within the framework of the Theory of Didactical Situations. Employing a qualitative approach with a phenomenological hermeneutic design, the study involved 64 undergraduate students from the Mathematics Education Department of a public university in Aceh, Indonesia, to identify the learning obstacles, and 35 students who participated in the implementation of the designed instructional intervention. Data were collected through document analysis, interviews, classroom observations, and audio–video recordings. The data analysis followed the three stages proposed by Miles and Huberman: data reduction, data display, and conclusion drawing. The findings revealed that students’ understanding of the theorems concerning parallelism conditions was impeded by three primary types of learning obstacles: epistemological, didactical, and ontogenic. To address these challenges, a GeoGebra-based didactical design was developed and implemented. The results demonstrated that this design effectively mitigated the identified obstacles and facilitated students’ construction of the theorems of parallelism conditions. Furthermore, the implementation appeared to foster a gradual shift in students’ learning orientation from procedural toward conceptual understanding, although this transition was not entirely uniform. Finally, the study highlights the pedagogical significance of integrating didactical situation theory into the learning process and employing dynamic visualization tools such as GeoGebra to support the transition from empirical to deductive mathematical reasoning.

Literasi dan numerasi merupakan salah satu keterampilan penting karena membantu manusia dalam memahami dan menyelesaikan masalah yang muncul dalam kehidupan sehari-hari. Pengabdian ini dilatarbelakangi oleh pentingnya penguatan terhadap keterampilan literasi dan numerasi yang dilakukan mulai dari sejak dini termasuk melalui proses pembelajaran di sekolah, baik dasar maupun perguruan tinggi. Meskipun begitu, penanaman numerasi di sekolah bukan berarti bahwa semua guru mengajarkan matematika, tetapi bagaimana guru mengintegrasikan numerasi dalam kurikulum melalui pembelajaran lintas mata Pelajaran. Guru masih kesulitan dalam mengembangkan modul ajar yang mengintegrasikan keterampilan literasi numerasi. Pengabdian ini bertujuan untuk menguatkan pemahaman guru terkait konsep literasi numerasi dan meningkatkan kemampuan guru lintas mata pelajaran dalam mengidentifikasi konten matematika untuk merancang modul ajar yang mengintegrasikan keterampilan numerasi. Metode pelatihan dan pendampingan dilakukan secara synchronous dan asynchonous di SMPN 6 Garut dengan peserta dari berbagai guru mata pelajaran. Hasil pengabdian menunjukkan terdapat penguatan pemahaman konsep literasi numerasi dengan capaian > 80% untuk masing-masing aspek, dan 8 kelompok guru mata pelajaran (100%) mampu mengidentifikasi konten matematika yang tepat untuk diintegrasikan pada modul ajar dengan capaian konten numerasi yang teridentifikasi sebesar 80 % (4 dari 5 domain matematika), selain itu guru mampu mengidentifikasi konteks personal, sosial budaya maupun saintifik dalam bidang ilmu yang diampu sebagai konteks masalah pada modifikasi modul ajar yang mengintegrasikan keterampilan numerasi. Domain bilangan menjadi tututan numerasi paling dominan dibandingkan domain matematika lainnya seperti aljabar, pengukuran, data dan ketidakpastian serta geometri. Kegiatan pengabdian berimplikasi juga terhadap peningkatan literasi digital guru dalam berkolaborasi dengan memanfaatkan spreadsheet dan google document.

The importance of mathematical creative thinking skills in the 21st century differs from the creative thinking skills of current elementary school students. A 5th-grade student at a public elementary school in West Bandung Regency, Indonesia, has low levels of creative thinking. This study aimed to analyze fifth-grade students' mathematical creative thinking skills during problem-solving, identify the underlying causes of their low performance, and propose instructional strategies to foster their development. The method used was qualitative, with a descriptive–interpretive design. Participants comprised 15 fifth-grade students from a single public elementary school in West Bandung Regency, Indonesia, selected via convenience sampling. The primary research instrument was the researcher, supported by a creative thinking skills test instrument and an interview guide. The results of this study are 1 student had a high level of creative thinking skills able to achieve indicators of flexibility, originality, awareness, and elaboration; 1 student had a moderate level of creative thinking skills able to achieve indicators of originality, awareness, and elaboration; and 13 students had low levels of creative thinking skills able to achieve indicators of fluency/originality/awareness/originality and awareness/ had not even achieved all indicators of mathematical creative thinking skills. Further analysis revealed fundamental misconceptions, particularly confusion between area and perimeter, fragmented procedural reasoning, and limited metacognitive verification during mathematical problem-solving. To improve students’ creative thinking skills, it is recommended to use learning activities oriented towards problem- and project-based learning, realistic mathematics, and mathematics textbooks that also support the problem-solving process. In conclusion, most fifth-grade students demonstrate low levels of mathematical creative thinking skills, shaped by conceptual misconceptions and limited metacognitive regulation, underscoring the importance of targeted, conceptually grounded, and problem-oriented instructional interventions. Keywords: creative thinking skills, mathematics, problem-solving.

Critical thinking skills are crucial for students to analyze and solve problems effectively, yet many still struggle in apply them comprehensively. This study aimed to examine students' critical thinking skills using a qualitative descriptive approach. The study used an essay-based assessment developed based on the framework of Perkins and Susilo et al., which includes four main indicators: clarification, judgment, inference, and strategy development. The findings indicated that students demonstrated partial critical thinking skills; most could analyze or clarify problems, while some could present problems with reasoning or examples and draw compelling conclusions. However, many students still struggled to develop effective problem-solving strategies. These results imply the need for improved instruction that places greater emphasis on strengthening problem-solving skills to enhance students' overall critical thinking skills.

The ability to solve mathematical word problems is an important skill for elementary school students because it involves contextual understanding and mathematical reasoning. However, in practice, students still often make mistakes in solving addition and subtraction word problems. This study aims to analyze the types and patterns of errors made by third-grade elementary school students in solving addition and subtraction word problems based on Newman's technique stages. This study used a descriptive qualitative approach with third-grade elementary school students in Sumedang Regency as subjects. Data were obtained through a written test consisting of three contextual word problems that were completed individually. Data analysis was carried out by identifying errors in the stages of reading, understanding the problem, transformation, process skills, and writing the final answer. The results showed that the most dominant errors occurred at the problem comprehension and transformation stages, especially in interpreting keywords and determining the correct mathematical operations. Errors at the process skills and final answer writing stages were also found, but these tended to be a consequence of previous errors. The conclusion of this study shows that students' errors in word problems are not only caused by their arithmetic abilities, but are more influenced by their weak contextual analysis and mathematical reasoning skills. Mathematics learning needs to emphasize the strengthening of mathematical literacy and the use of the Newman Technique as a tool for diagnosing students' learning difficulties.

Abstrak: This study aims to analyze the effectiveness of GASING Method (Easy, Fun, and Enjoyable) in improving numeracy competencies among teachers and students in Teluk Wondama Regency, West Papua one of Indonesia's underdeveloped frontier regions. Using a quantitative approach with a pre-experimental one-group pretest-posttest design, the study involved 46 teachers and 96 students from various primary schools who participated in a three-week intensive program (10–30 June 2025). The research instruments consisted of written arithmetic tests covering five core competencies: Basic Number Sense (Bakal Kubagi), Addition, Multiplication, Subtraction, and Division. Results demonstrated highly significant improvements: teachers' mean scores increased from 32.33 (pre-test) to 79.83 (post-test) with an N-Gain of 0.702 (High category), while students' mean scores rose from 10.51 (pre-test) to 75.51 (diagnostic test) with an N-Gain of 0.727 (High category). Paired Sample t-Test analyses revealed statistically significant differences (α = 0.05) across all measured competencies. Both groups' N-Gain scores substantially exceeded the international average of 0.34 reported in comparable intervention studies (Westphale et al., 2022). These findings demonstrate that the GASING Method with its sequential concrete–abstract–mental computation approach delivered through playful, interactive activities is an effective and replicable solution for addressing the numeracy crisis in Indonesia's remote regions. This research contributes to evidence-based education policy development in underserved areas and reinforces the importance of integrated interventions targeting both teachers and students simultaneously within a unified learning ecosystem.
