Abstract

Artikel ini membahas tentang pengembangan modul dan video pembelajaran matematika pada materi Dimensi Tiga. Pengembangan dengan menggunakan model ASSURE, yaitu Analyzer learner, State standards and objectives, Select strategies, Technology media and materials, Utilize technology, Require learner participation, dan Evaluate and revise. Kualitas modul dan video dalam pengembangan ini dilihat dari dua aspek yaitu validitas dan kepraktisan. Instrumen penelitian yang digunakan adalah lembar validasi modul dan video, lembar angket respon peserta didik dan lembar angket respon guru. Hasil penelitian mengungkapkan penilaian dari validator terhadap modul dan video memperoleh kriteria valid. Selanjutnya, penerapan modul dan video dalam pembelajaran mendapatkan respon positif dari guru dengan rata-rata persentase 86.08% dan respon positif dari peserta didik dengan rata-rata persentase 77.56%. Nilai rata-rata respon guru dan peserta didik ini menunjukkan kategori sangat baik, sehingga modul dan video dapat dikatakan memenuhi kriteria kepraktisan. Hal ini menunjukkan bahwa modul dan video pembelajaran memenuhi aspek valid dan praktis sehingga layak digunakan dalam pembelajaran.

Abstract

This study aims to explore the understanding of the concept of exponents of mathematics education students in terms of cognitive style. This type of research is qualitative with a case study approach. The subjects in this study were 2 mathematics education students consisting of 1 student with reflective cognitive style and 1 student with impulsive cognitive style. The instruments used in this study were 2 items of exponent problem solving and interview guidelines. The results showed that Reflective Cognitive Style Subjects were able to fulfill all indicators of understanding the concept of exponents, namely indicators of exponent problem solving, identifying positive, negative, and zero exponents, using exponent rules, understanding roots and fractions as exponents, and identifying and correcting exponent misconceptions. Meanwhile, Impulsive Cognitive Style Subjects were only able to fulfill 4 indicators of understanding the concept of exponents. Impulsive Cognitive Style Subjects were not able to fulfill the indicators of identifying and correcting exponent misconceptions. The advantage in this study is to fill the gap in the literature by connecting the understanding of the concept of exponents and cognitive style variations. Furthermore, making mathematics education students as research targets. It offers novelty because their understanding of exponents has direct implications on how they teach the concept in the future.

Abstract

Penelitian ini bertujuan untuk menawarkan perspektif baru dalam eksplorasi nilai konstanta matematika π melalui studi analitis estimasi nilainya. Pendekatan yang digunakan adalah perhitungan luas dan keliling poligon beraturan yang didasarkan pada rumus luas segitiga dan aturan kosinus. Nilai π yang diperoleh dari perhitungan poligon dibandingkan dengan nilai π yang umum dikenal hingga delapan digit desimal (3,14159265). Hasil penelitian menunjukkan bahwa meskipun jari-jari lingkaran divariasikan, nilai konstanta yang dihasilkan dari perhitungan luas poligon bersegi 71094 identik dengan nilai π hingga delapan digit desimal. Sementara itu, perhitungan keliling poligon bersegi 25406 juga menghasilkan nilai konstanta yang identik dengan nilai π hingga delapan digit desimal (3,14159265). Namun, untuk perhitungan keliling poligon bersisi 71094 menghasilkan nilai konstanta dengan perbedaan satu digit desimal terakhir (3,14159266). Studi ini memberikan wawasan mengenai konvergensi nilai π melalui pendekatan geometris poligon beraturan.

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.
