Abstrak
Pembelajaran matematika SD, khususnya geometri, kerap menyulitkan siswa akibat rendahnya kemampuan visualisasi spasial. Penelitian ini menguji efektivitas model Discovery Learning berbantuan media BASUKI-MAT terhadap kemampuan visualisasi spasial siswa SD. Penelitian ini menggunakan metode kuantitatif dengan desain One Group Pretest-Posttest pada 40 siswa SD 1 Getas Pejaten tahun ajaran 2025/2026. Instrumen pretest dan posttest digunakan untuk pengumpulan data, yang kemudian dianalisis menggunakan uji normalitas serta N-Gain. Hasil uji normalitas Shapiro Wilk menunjukkan bahwa data berdistribusi normal. Sedangkan, hasil uji N-Gain sebesar 56,71% menempatkan pada kategori cukup efektif, didukung kenaikan rata-rata pada setiap indikator. Temuan ini memberikan kontribusi praktis bagi guru dalam merancang pembelajaran yang lebih interaktif. Kesimpulannya, model Discovery Learning berbantuan media BASUKI-MAT terbukti cukup efektif digunakan sebagai strategi alternatif untuk mengoptimalkan kemampuan visualisasi spasial matematika siswa SD secara berkelanjutan dan optimal.

Elementary geometry often challenges students due to weak spatial visualization skills. This study examines the effectiveness of the Discovery Learning model assisted by BASUKI-MAT media in enhancing elementary students’ mathematical spatial visualization. Employing a quantitative one-group pretest-posttest design, data were collected from 40 students at SD 1 Getas Pejaten during the 2025/2026 academic year. Pretest and posttest instruments measured skill development, with data analyzed using normality tests and N-Gain scores. Shapiro-Wilk results confirmed normally distributed data. The N-Gain score reached 56.71%, indicating moderate effectiveness, supported by consistent improvement across all indicators. These findings offer practical insights for teachers designing interactive mathematics instruction. Conclusively, Discovery Learning integrated with BASUKI-MAT serves as a moderately effective strategy to sustainably improve students’ spatial visualization abilities in mathematics.
