Abstract
Penelitian ini bertujuan untuk mengetahui pengaruh model Discovery Learning yang didukung oleh media PowerPoint interaktif terhadap pemahaman konsep matematis siswa kelas IV sekolah dasar. Selain itu, penelitian ini juga membandingkan hasil pemahaman konsep antara siswa yang belajar menggunakan model Discovery Learning berbantuan PowerPoint interaktif (kelompok eksperimen) dan siswa yang mendapatkan pembelajaran melalui model Problem Based Learning dengan media gambar cetak (kelompok kontrol). Pendekatan yang digunakan adalah kuasi eksperimen dengan desain Nonequivalent Control Group Design. Pengumpulan data dilakukan melalui tes uraian yang disusun berdasarkan enam indikator pemahaman konsep matematis. Analisis data dilakukan dengan Paired Sample t-Test, Independent Sample t-Test, dan regresi linier sederhana. Hasil penelitian menunjukkan bahwa siswa pada kelompok eksperimen mengalami peningkatan pemahaman yang lebih signifikan, ditunjukkan oleh rata-rata skor posttest sebesar 33,79 dibandingkan 29,38 pada kelompok kontrol. Analisis N-Gain juga mengonfirmasi keunggulan pendekatan Discovery Learning, dengan skor peningkatan sebesar 0,63 pada kelompok eksperimen dan 0,42 pada kelompok kontrol. Meskipun keduanya berada dalam kategori sedang, peningkatan pemahaman pada kelompok eksperimen secara kuantitatif lebih tinggi. ----- The aim of this research was to explore how the Discovery Learning model, supported by interactive PowerPoint media, influences the mathematical concept understanding of fourth-grade elementary students. Additionally, the study sought to compare the conceptual understanding outcomes between students exposed to Discovery Learning with interactive PowerPoint (experimental group) and those taught through the Problem Based Learning model using printed picture media (control group). This study adopted a quasi-experimental approach using a Nonequivalent Control Group Design. Data were collected using a descriptive test aligned with six established indicators of conceptual understanding in mathematics. Statistical analysis was conducted through Paired Sample t-Test, Independent Sample t-Test, and simple linear regression. Findings revealed that students in the experimental group showed a notably greater improvement, as reflected by their average posttest score of 33.79, compared to 29.38 in the control group. The average N-Gain analysis further confirmed the advantage of the Discovery Learning approach, with an improvement score of 0.63 for the experimental group and 0.42 for the control group. While both gains fell within the moderate category, the experimental group demonstrated a quantitatively higher increase in understanding.
