Abstract
ABSTRAK Penelitian eksperimen semu ini bertujuan untuk menguji pengaruh model pembelajaran Problem-Based Learning terhadap kepercayaan diri siswa kelas V Sekolah Dasar pada mata pelajaran Ilmu Pengetahuan Sosial (IPS). Dengan menggunakan desain Nonequivalent Control Group Design terhadap sampel sebanyak 60 siswa, data dikumpulkan melalui angket kepercayaan diri yang disusun berdasarkan indikator Lauster dan selanjutnya dianalisis menggunakan uji-t sampel independen. Hasil penelitian menunjukkan adanya pengaruh yang signifikan secara statistik, dibuktikan dengan perolehan nilai t-hitung sebesar -15,962 (Sig.<0,05). Selain itu, kelas eksperimen mencapai skor N-Gain sebesar 64,82% yang termasuk dalam kategori "Cukup Efektif", secara signifikan melampaui skor kelas kontrol yang hanya mencapai 32,86% dengan kategori "Kurang Efektif". Sebagai simpulan, implementasi model Problem-Based Learning terbukti sangat efektif dalam meningkatkan kepercayaan diri siswa kelas V Sekolah Dasar. Kata Kunci: Problem-Based Learning, Kepercayaan Diri, Model Konvensional Pendekatan Ekspositori, IPS, SD. ***** ABSTRACT This quasi-experimental study aims to investigate the impact of the Problem-Based Learning model on the self-confidence of fifth-grade elementary school students in Social Studies. Employing a shattered Nonequivalent Control Group Design with a sample of 60 students, data were collected through a self-confidence questionnaire developed based on Lauster's indicators and subsequently analyzed using independent sample t-tests. The results indicate a statistically significant influence, evidenced by a t-value of -15.962 (Sig. < 0.05). Furthermore, the experimental group achieved an N-Gain score of 64.82%, categorized as "Moderately Effective", significantly outperforming the control group's score of only 32.86%, categorized as "Ineffective". In conclusion, the implementation of the Problem-Based Learning model is proven to be highly effective in enhancing the self-confidence of fifth-grade elementary school students. Keywords: Problem-Based Learning, Self-Confidence, Conventional Model with Expository Approach, Social Studies, Elementary School.
