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

Low student interest and achievement in mathematics remain important educational issues that require attention in Gorontalo Province. This condition calls for a development program that is not only competition-oriented but also capable of fostering learning motivation, self-confidence, competitiveness, critical thinking skills, and problem-solving abilities. This community service activity was implemented through the 2025 Mathematics Scientific League (LIMIT ’25) as a platform for developing the academic potential of senior high school students across Gorontalo Province. The purpose of this activity was to provide an educational, healthy, collaborative, and inspiring mathematics competition for students while strengthening networks among schools, teachers, university students, and higher education institutions. The implementation method used a community-based participatory action approach consisting of socialization, participant registration, technical preparation, competition implementation, evaluation, and reflection. This activity involved lecturers and university students as organizers, mathematics teachers as mentors, and students as the main participants. LIMIT ’25 was attended by 34 teams or 68 students from six regencies/cities in Gorontalo Province. Based on the implementation results, observations, evaluations, and participant reflections, this activity encouraged active student participation, increased positive competitive spirit, strengthened teamwork, and provided a challenging and meaningful mathematics learning experience. Participants also had the opportunity to test their conceptual understanding, reasoning strategies, and decision-making accuracy in solving non-routine problems. In addition, this activity created a space for communication among senior high school mathematics teachers in supporting sustainable student achievement development. This program can also be replicated as an annual agenda to expand the impact of regional mathematics development. Thus, LIMIT ’25 demonstrates its potential as a medium for mathematics achievement development, numeracy literacy strengthening, and community-based educational ecosystem development in Gorontalo through sustainable collaboration between universities and schools
