Abstract

Three-dimensional material, particularly the topic of distance and angles between geometric elements, is one of the most difficult parts for high school students because it requires high visualization and spatial reasoning skills. This study aims to develop a systematic algorithmic strategy to solve distance and angle problems in three-dimensional space in a more structured and student-friendly manner. The research approach used is qualitative-descriptive with analysis of textbooks, curriculum documents, and empirical experiences in teaching spatial geometry. The results of the study produced two main algorithms, namely the distance algorithm and the angle algorithm, each of which is arranged in logical steps starting from translating the problem into a drawing, identifying auxiliary triangles, analyzing the types of triangles, to applying relevant trigonometric theorems such as Pythagoras and the cosine rule. This strategy has been proven to strengthen the connection between students' conceptual understanding and procedural skills in solving problems. The systematic application of algorithms helps students build spatial visualization skills, improve thinking efficiency, and foster algorithmic thinking patterns in mathematics learning.

Abstract

This study aims to analyze the creativity level of Mathematics Education students at Muhammadiyah University Gorontalo in the Basic Statistics course. Creativity is understood as the ability to think divergently, which plays a role in mastering mathematical concepts and applying ideas in real contexts. The method used is a descriptive quantitative approach with a sample of 13 students selected purposively. Data were obtained through a creativity questionnaire based on Torrance's four indicators, namely fluency, flexibility, originality, and elaboration. The instrument used a 1–5 Likert scale, with categories: 1 = strongly disagree, 2 = disagree, 3 = unsure, 4 = agree, and 5 = strongly agree. The data were analyzed using descriptive statistics and the Kolmogorov–Smirnov and Shapiro–Wilk normality tests with the help of SPSS 26. The results showed that 2 students (15.4%) were in the low category, 7 students (53.8%) were in the medium category, and 4 students (30.8%) were in the high category with an average of 58.1%. The Kolmogorov–Smirnov significance value was 0.093 and the Shapiro–Wilk value was 0.238 (> 0.05), indicating that the data were normally distributed. These findings confirm that student creativity is in the moderate category and needs to be improved, especially in terms of flexibility of thinking and originality.

Abstract

Penelitian ini bertujuan untuk mengeksplorasi sejauh mana perbedaan gender mempengaruhi numerasi matematika mahasiswa PGSD. Jenis penelitian ini adalah kualitatif dengan pendekatan studi kasus. Subjek dalam penelitian ini adalah 2 mahasiswa dengan kemampuan kategori tinggi. Instrumen yang digunakan adalah 2 butir soal Asesemen Kompetensi Minimum dan pedoman wawancara. Metode yang digunakan untuk pengumpulan data yakni metode tes, wawancara, dan domunentasi. Teknik analisis data yang digunakan adalah model Miles, Huberman, dan Saldana yang meliputi kondensasi data, penyajian data, dan penarikan kesimpulan. Perbedaan gender dalam konteks ini tidak mennujukkan perbedaan signifikan dalam kemampuan berhitung, tetapi terlihat pada pendekatan berpikir dan kedalaman pemahaman konsep matematis. Subjek Laki-Laki cenderung berpikir analitik, logis, dan reflektif, menunjukkan keunggulan dalam pemahaman konsep dan strategi pemecahan masalah. Subjek Perempuan berpikir tekstual, prosedural, dan sistematis, menunjukkan keunggulan dalam ketelitian dan keteraturan langkah, tetapi masih kurang dalam pemahaman makna konseptual dan evaluasi hasil. Dengan demikian, perbedaan gender berpengaruh pada gaya kognitif dan strategi numerasi matematika, bukan pada kemampuan berhitung dasar. Subjek Laki-Laki lebih menonjol pada penalaran konseptual, sedangkan Subjek Perempuan lebih kuat pada ketelitian prosedural.

Abstract

This study aims to develop and test the validity of pretest and posttest instruments for measuring students' mathematical reasoning and creativity in the development of STEM-based e-modules integrated with the Project-Based Learning (PjBL) model. Mathematical reasoning and creativity are considered higher-order thinking skills that are important in understanding mathematical concepts and solving contextual problems. The research was conducted at SMP Negeri 1 Telaga, Gorontalo Regency, using the ADDIE Research and Development (R&D) model, which was limited to the analysis, design, and instrument development stages. The research instruments were pretest and posttest tests of students' mathematical reasoning and creativity, which were compiled based on competency indicators and mathematical thinking ability indicators. The instruments were validated by subject matter experts and education practitioners using a Likert scale. Data analysis techniques used content validity analysis to determine the level of instrument feasibility. The results showed that the developed pretest and posttest instruments were highly valid and feasible for measuring students' mathematical reasoning and creativity. These findings form the basis for conducting practicality and effectiveness tests of the STEM-PjBL-based mathematics e-module in the next stage of research.

Abstract

This study describes students’ thinking processes in solving inverse proportion problems based on mathematical ability. The study employed a qualitative descriptive design involving three students categorized as having high, moderate, and low mathematical ability. Data were collected through a written inverse proportion task and task-based interviews organized according to four problem-solving stages: understanding the problem, devising a plan, carrying out the plan, and looking back. The task asked students to determine the completion time when 20 workers who could finish a job in 30 days were increased to 50 workers. The results showed that the high-ability student recognized the inverse relation, used the constant-product model 20 × 30 = 50 × x, obtained 12 days, and verified the answer. The moderate-ability student treated the situation as direct proportion by writing 20 : 50 = 30 : x, indicating relational misconception. The low-ability student recognized the inverse relation but had difficulty with multiplication and division and did not check the answer. The findings imply that inverse proportion instruction should emphasize contextual relations, strategy selection, computational fluency, and reflective checking.
