Abstract

Innovative and engaging learning media are needed to overcome elementary school students' low interest and difficulty in understanding basic math operations. Therefore, this study aims to develop and test the validity, practicality, and effectiveness of educational game-based math learning media in understanding basic math calculation operations called Astromath. This media is designed to assist elementary school students in understanding mathematical concepts more enjoyably and interactively. The research employed the Research and Development (R&D) method with the ADDIE development model, which includes the stages of analysis, design, development, implementation, and evaluation. Two material experts validated with a result of 85.83% (very valid category) and two media experts with a result of 90% (very valid category). The practicality test was conducted on two teachers and four first-grade elementary school students. The results of the teachers' assessments showed an average score percentage of 84.37%, categorized as very practical. In comparison, the students' practicality test results obtained an average percentage of 91.1%, which also fell into the very practical category. Furthermore, the pre-test and post-test results demonstrated a significant increase in students' understanding after using Astromath. Therefore, Astromath is declared effective, practical, and suitable for use as an alternative interactive and enjoyable learning media in elementary schools.

Abstract

Pembelajaran konsep distribusi Bernoulli masih dirasakan abstrak oleh mahasiswa sehingga diperlukan media konkret yang dapat menjembatani pemahaman antara teori dan pengalaman empiris. Penelitian ini bertujuan mengembangkan media Bernoulli Box berbantuan LKPD untuk mengenalkan konsep dasar Distribusi Bernoulli serta mengetahui validitas dan kepraktisan produk yang dikembangkan. Metode penelitian menggunakan Design Research tipe Development Studies yang meliputi preliminary phase dan prototyping phase melalui self-evaluation, expert review, one-to-one, dan small group. Subjek penelitian yaitu sembilan mahasiswa semester 1 Program Studi Pendidikan Matematika Universitas Sriwijaya yang dipilih secara purposive. Data dikumpulkan melalui walkthrough, lembar validasi, observasi, tes dalam LKPD, wawancara, dan angket kepraktisan, kemudian dianalisis secara deskriptif. Hasil validasi ahli menunjukkan bahwa Bernoulli Box dan LKPD memiliki validitas isi, konstruk, dan bahasa yang baik. Uji one-to-one dan small group menunjukkan bahwa mahasiswa mampu mengikuti aktivitas dalam LKPD secara mandiri dan memahami dua kemungkinan hasil percobaan Bernoulli dengan benar. Hasil angket kepraktisan memperoleh persentase 98,08% yang termasuk kategori sangat praktis. Dengan demikian, media dan LKPD yang dikembangkan layak digunakan sebagai alternatif pembelajaran untuk memperkuat pemahaman konsep Distribusi Bernoulli.
