Abstract

Purpose: This study aims to develop an open-ended diagnostic test to identify pre-service mathematics teachers’ Dominant Mathematical Representations (DMR) in Real Analysis, with a specific focus on convergent sequences. Method: A Research and Development (R&D) approach was employed using Plomp’s development model, which includes preliminary research, prototyping, and assessment phases. The diagnostic instrument was constructed based on representational theory and consisted of six open-ended tasks designed to elicit representational choice, integration, and transferability. Content validity and linguistic clarity were evaluated by two mathematics education experts and one language expert. A limited field trial involving 19 pre-service mathematics teachers was conducted to examine the instrument’s validity and practicality. Data were collected through the diagnostic test, expert validation sheets, and a student response questionnaire, and analyzed descriptively using qualitative feedback and quantitative percentage-based indicators. Findings: The results indicate that the developed diagnostic test demonstrates strong content validity, with a mean validity score of 85.4%, classified as very valid. The practicality evaluation yielded a mean score of 83.7%, indicating that the instrument is very practical in terms of clarity, format, language, and time allocation. Expert review confirmed alignment between the test items and the DMR construct, while student responses indicated feasibility and comprehensibility. Significance: This study contributes to mathematics education assessment by operationalizing Dominant Mathematical Representations as an explicitly assessable construct through open-ended diagnostic tasks, providing a foundation for representation-sensitive instruction in Real Analysis.

Abstract

The development of Artificial Intelligence (AI) technology opens up significant opportunities for improving the quality of mathematics learning. However, many high school mathematics teachers are still unfamiliar with the use of AI, particularly the use of the Python programming language as a learning support medium. This community service activity aims to improve the knowledge, understanding, and skills of high school Mathematics MGMP teachers in utilizing Python-based AI technology in the learning process. The implementation method includes a preparatory stage in the form of coordination with partners, observation, and interviews to identify teacher needs, and an implementation stage consisting of two training sessions. The first training phase focused on providing conceptual material regarding AI applications in learning, while the second training phase included practical assistance in creating AI-based learning media using Python. The results of the activity showed an increase in teachers' understanding of AI concepts and practical skills in using Python to develop simple interactive quizzes in mathematics learning. Furthermore, participants demonstrated active and collaborative participation throughout the activity. Thus, this community service activity contributed to improving teachers' technological literacy and encouraging innovation in more interactive mathematics learning. It is recommended that similar activities be carried out continuously with a broader scope of material to optimize the use of AI in learning

Abstract

This study develops and evaluates an instructional model that integrates Guided Discovery Learning with Mathematical Reasoning and Proving (MRP) Tasks to support undergraduate students’ construction of mathematical proofs in Real Analysis. The research focuses on two foundational criteria in instructional development, namely validity and practicality. Expert review involving five specialists produced high Aiken V and ICC values, indicating strong conceptual coherence, structural alignment, and reliability of judgment across components of the model. Practicality was examined through one to one evaluation, small group testing, and a field implementation involving lecturers and students. Across these stages, the model received high ratings for clarity of instructional flow, readability of tasks, feasibility of classroom enactment, and support for structured reasoning processes. The findings demonstrate that the model is both theoretically sound and operationally feasible, providing a coherent pedagogical trajectory that guides learners from exploration toward formal proof construction. This study contributes a validated instructional model and establishes a foundation for future research on its effectiveness and broader applicability in advanced mathematics learning.

Abstract

Mathematical abstraction is an important aspect in mathematics learning, especially in helping students form and understand geometric concepts such as quadrilaterals. However, in practice, students' mathematical abstraction process does not always occur uniformly. This is due to differences in individual characteristics, one of which is learning style. Therefore, this study aims to describe the profile of students' mathematical abstraction in forming the concept of quadrilaterals in terms of learning style. This study uses a qualitative approach with a descriptive type. The research subjects consisted of three seventh-grade junior high school students with visual, auditory, and kinesthetic learning styles. Data were collected through a learning style questionnaire, mathematical abstraction tasks on quadrilaterals, and interviews. Data analysis used data condensation, data display, and conclusion drawing and verification. The results of the study showed that students' mathematical abstraction processes differed in each learning style. Visual students were able to go through all aspects of mathematical abstraction (recognizing, building-with, constructing, and consolidation) gradually by utilizing visual representations. Auditory students also achieved all aspects by relying on verbal understanding, although the constructing and consolidation aspects were not systematically arranged. Meanwhile, kinesthetic students rely more on concrete experiences and physical activity in recognizing and consolidating. Therefore, it can be concluded that learning styles determine how students carry out the mathematical abstraction process in forming the concept of quadrilaterals, so this needs to be taken into consideration when designing mathematics learning.

Abstract

Keterampilan berpikir kreatif merupakan kompetensi penting yang harus dikembangkan pada siswa. Namun, pembelajaran di sekolah masih berpusat pada guru dan belum sepenuhnya memperhatikan kebutuhan belajar serta karaktersitik siswa sehingga keterampilan berpikir kreatif siswa masih rendah. Penelitian ini bertujuan untuk mengetahui pengaruh pembelajaran berdiferensiasi terhadap keterampilan berpikir kreatif siswa dalam pembelajaran matematika ditinjau dari motivasi belajar. Penelitian menggunakan pendekatan kuantitatif dengan jenis penelitian eksperimen semu dan desain faktorial 2×3. Populasi penelitian adalah seluruh siswa kelas VII SMP Negeri se-Kecamatan Sirenja, dengan sampel diambil menggunakan teknik simple random sampling sehingga diperoleh dua kelas di SMP Negeri 3 Sirenja, yaitu kelas eksperimen yang menerapkan pembelajaran berdiferensiasi (n=31) dan kelas kontrol yang menerapkan pembelajaran konvensional (n=32). Data dikumpulkan menggunakan tes keterampilan berpikir kreatif dan angket motivasi belajar. Analisis data dilakukan menggunakan uji Independent Sample t-test dan ANOVA dua arah. Hasil penelitian menunjukkan: (1) terdapat pengaruh signifikan pembelajaran berdiferensiasi terhadap keterampilan berpikir kreatif siswa (sig. 0,020 < 0,05); (2) tidak terdapat pengaruh signifikan pembelajaran berdiferensiasi terhadap keterampilan berpikir kreatif siswa yang memiliki motivasi belajar tinggi (sig. 0,089 > 0,05); (3) terdapat pengaruh signifikan pembelajaran berdiferensiasi terhadap keterampilan berpikir kreatif siswa yang memiliki motivasi belajar sedang (sig. 0,035 < 0,05); (4) terdapat pengaruh signifikan pembelajaran berdiferensiasi terhadap keterampilan berpikir kreatif siswa yang memiliki motivasi belajar rendah (sig. 0,007 < 0,05); dan (5) tidak terdapat interaksi signifikan antara pembelajaran berdiferensiasi dan motivasi belajar terhadap keterampilan berpikir kreatif siswa (sig. 0,499 > 0,05). Temuan ini mengimplikasikan bahwa pembelajaran berdiferensiasi efektif meningkatkan keterampilan berpikir kreatif, terutama bagi siswa dengan motivasi belajar sedang dan rendah.

Abstract

Purpose: This study explores the reflective processes of prospective mathematics teachers in proof construction, analyzed through Toulmin’s argumentation framework and Surbeck’s reflective thinking phases. Method: This study employed a qualitative case study design. Twenty prospective mathematics teachers at a university in Palu City were asked to solve a mathematical proof task. Their solutions were categorized into four types, representing variations in argumentation and reflective processes. One participant from each type was selected for interviews to obtain more in-depth insights. The collected data were analyzed using thematic analysis, involving coding and theme development guided by Toulmin’s and Surbeck’s frameworks. Findings: The results indicate that prospective teachers who demonstrated a relatively complete reflective process in proof construction were able to identify relevant information, develop logical reasoning, and evaluate their proof steps. In contrast, those who exhibited transitional, limited, and minimally developed reflective processes showed increasing difficulties in constructing and evaluating their proofs. Significance: These findings suggest the need to integrate reflective thinking and structured argumentation explicitly in proof-based instruction, particularly by supporting students in developing and evaluating warrants and backing during proof construction.
