Efektivitas Model Discovery Learning Berbantuan Ensiklopedia terhadap Pemahaman Konsep Materi Ekosistem Siswa Kelas X SMA

Abstract

This study aimed to determine the effectiveness of the Discovery Learning model assisted by an encyclopedia on students' conceptual understanding of ecosystem materials in tenth-grade senior high school students. The research employed a quantitative approach using a quasi-experimental method with a Nonequivalent Control Group Design. The population consisted of all tenth-grade students at SMA Karya Sekadau, while the sample was selected using purposive sampling to obtain an experimental class and a control class. The research instrument was a conceptual understanding test administered through pretest and posttest. Data were analyzed using normality tests, homogeneity tests, hypothesis testing, and learning improvement analysis. The results indicated that the implementation of the Discovery Learning model assisted by an encyclopedia had a more positive effect on students' conceptual understanding than conventional learning. Students in the experimental class demonstrated a higher improvement in conceptual understanding than those in the control class. Therefore, the Discovery Learning model assisted by an encyclopedia is effective in improving students' conceptual understanding of ecosystem materials.
