Abstract

Purpose: This study explore the self-determination profiles of postgraduate mathematics education students, emphasizing how autonomy, competence, and relatedness contribute to their readiness and motivation to pursue teaching as a professional career. Method: A quantitative-descriptive approach was employed, using a validated self-determination questionnaire distributed to 47 postgraduate students and alumni from 2020 to 2024. The instrument measured three SDT dimensions (autonomy, competence, and relatedness) through 24 positive and negative statements. Descriptive and comparative analyses were applied to identify dominant motivational patterns. Finding: Findings revealed high mean scores for autonomy and competence, indicating students’ confidence in decision-making and mastery of pedagogical knowledge. Relatedness also scored strongly, reflecting solid interpersonal engagement with peers and lecturers. Collectively, these outcomes depict a balanced SDT profile among future mathematics teachers. Significance: The study demonstrates that strong self-determination enhances students’ readiness to enter the teaching profession with intrinsic motivation, pedagogical confidence, and collaborative awareness. Strengthening these three SDT dimensions within teacher education curricula can cultivate mathematics educators who are reflective, adaptive, and committed to continuous professional development. This research underscores that fostering autonomy, competence, and relatedness is not only central to improving mathematics learning but also to shaping sustainable teacher professionalism in the modern educational landscape.

Abstract

This study aims to describe the mathematical literacy skills of male Grade IX students SMP Negeri 6 Medan, to describe the mathematical literacy skills of female Grade IX students SMP Negeri 6 Medan, and to determine the level of achievement of mathematical literacy skills of Grade IX students SMP Negeri 6 Medan. This research is a descriptive qualitative study. The subjects of this research were 26 students of class IX-K at SMP Negeri 6 Medan in the academic year 2025/2026. Data collection in this study was carried out through mathematical literacy tests and interviews. The results of the study show: (1) Male students had average percentage scores on three indicators of mathematical literacy, namely understanding (43.33%), application (50%), and reasoning (8.33%). (2) Female students had average percentage scores on three indicators of mathematical literacy, namely understanding (68.18%), application (81.82%), and reasoning (40.91%). (3) The achievement level of mathematical literacy skills for female students was 61.11%, which falls into the ‘fair’ category, while the achievement level for male students was 47.22%, which falls into the ‘poor’ category.

Abstract

This study aims to analyze the mental models and geometric strategies of prospective mathematics teachers in representing plane figures, particularly triangles and quadrilaterals. A qualitative descriptive method was employed involving 27 undergraduate students from Universitas Negeri Medan in the 2023/2024 academic year. Data were collected through a structured drawing task covering various types of triangles and quadrilaterals and were analyzed using data reduction, data display, and conclusion drawing techniques. The findings reveal that students predominantly rely on prototypical representations in drawing geometric figures, such as right, isosceles, and equilateral triangles, as well as squares and rectangles. Their partitioning strategies are also dominated by simple approaches, particularly vertical and horizontal divisions, which are considered cognitively efficient and easier to execute. These results indicate that students’ mental models are strongly influenced by prior learning experiences, visual prototypes, and cognitive load during problem-solving processes. Overall, students’ mental representations have not yet fully developed toward flexible and formal conceptual understanding in geometry.

Abstract

Kemampuan komunikasi matematika siswa masih sangat rendah. Penelitian ini bertujuan untuk menganalisis pengaruh model pembelajaran Two Stay Two Stray terhadap kemampuan komunikasi matematis siswa kelas XI. Sampel penelitian adalah siswa kelas XI Sains A2 dan A4 yang berjumlah 72 siswa. Metode yang digunakan adalah quasi eksperiment dengan desain penelitian pretest-posttest control group design. Instrumen penelitian berupa lima tes uraian untuk mengukur kemampuan komunikasi matematis. Data dianalisis menggunakan Independent Sample T-Test dengan nilai signifikansi yang diperoleh yaitu 0,000, dari hasil tersebut diketahui bahwa nilai signifikansi 0,000 < 0,05. Adapun nilai effect size sebesar 1,7 yang menunjukkan bahwa terdapat pengaruh model Two Stay Two Stray sebesar 95,5% terhadap kemampuan komunikasi matematis siswa kelas XI. Dengan demikian, dapat disimpulkan bahwa terdapat pengaruh model pembelajaran Two Stay Two Stray terhadap kemampuan komunikasi matematis siswa kelas XI. Students' mathematical communication ability in schools are still very low. This study aims to analyze the effect of the two stay two stray learning model on the mathematical communication ability of grade XI students. The research sample was 72 grade XI A2 and A4 Science students. The method used was a quasi-experimental study with a pretest-posttest control group design. The research instrument was five essay tests to measure mathematical communication ability. The data were analyzed using the Independent Sample T-Test with a significance value of 0,000, from these results it is known that the significance value of 0,000 < 0,05. The effect size value of 1,7 indicates that there is an influence of the Two Stay Two Stray model of 95,5% on the mathematical communication ability of grade XI students. Thus, it can be concluded that there is an influence of the Two Stay Two Stray learning model on the mathematical communication ability of grade XI students.
