Pengaruh model pembelajaran somatic, auditory, visual, intellectual terhadap kemampuan representasi matematis peserta didik

Abstract

Penelitian ini menganalisis perkembangan kemampuan representasi matematis selama penerapan model Somatic, Auditory, Visual, Intellectual (SAVI) dan menguji perbedaan capaian akhir dengan pembelajaran konvensional pada materi Barisan dan Deret. Penelitian menggunakan pendekatan deskriptif dan eksperimen semu dengan rancangan non-equivalent posttest-only control group design. Sampel terdiri atas 72 peserta didik kelas XI Fase F SMAN 1 Koto XI Tarusan tahun ajaran 2026/2027, yaitu 36 peserta didik pada kelas eksperimen dan 36 pada kelas kontrol. Perkembangan kelas eksperimen ditelaah melalui enam kuis, sedangkan capaian akhir diukur dengan tes uraian tiga soal. Rata-rata nilai kuis meningkat dari 59,52 pada kuis pertama menjadi 80,10 pada kuis keenam. Rata-rata tes akhir kelas eksperimen adalah 70,26 (median = 72,5; SD = 23,6), sedangkan kelas kontrol 62,85 (median = 67; SD = 17,5). Uji normalitas menunjukkan data kedua kelompok tidak berdistribusi normal; karena itu digunakan uji Mann–Whitney. Hasilnya menunjukkan perbedaan yang signifikan secara statistik dengan p = 0,042 (uji satu arah sebagaimana hipotesis penelitian). Temuan mendukung potensi SAVI dalam konteks penelitian ini, tetapi generalisasi dibatasi oleh penggunaan dua kelas pada satu sekolah dan rancangan tanpa pretest pada kelompok sampel.
