The Effect of the Problem Based Learning (PBL) Model Assisted by Quizizz Media on IPAS Learning Outcomes of Grade IV Elementary School Students in Sanggau Regency

Abstract : Background: Social Science and Natural Science (IPAS) learning in elementary schools faces significant challenges, particularly in teaching the topic of social and cultural diversity in Indonesia. Conventional, teacher-centered approaches have failed to stimulate students’ critical thinking skills and active engagement, especially in the multi-ethnic context of Sanggau Regency, West Kalimantan. Objectives: This study aims to: (1) test the significant effect of the Problem Based Learning (PBL) model assisted by Quizizz media on IPAS learning outcomes of Grade IV students; (2) describe the effectiveness of Quizizz in improving motivation and cognitive learning outcomes on the social and cultural diversity topic through PBL; and (3) analyze differences in learning outcomes between students taught using PBL assisted by Quizizz and those taught using conventional methods at SD Negeri in Sanggau Regency. Methods: This study employs a quantitative approach with a Quasi-Experimental Research method using a Non-Equivalent Control Group Design. The study population comprises 45 Grade IV students across three SD Negeri in Sanggau Regency: SD Negeri 01 Sanggau (experimental), SD Negeri 02 Balai Karangan (experimental), and SD Negeri 14 Sekumpai (control). Samples were selected using purposive sampling. Data collection instruments include direct observation sheets, teacher performance observation sheets, a learning achievement test (20 multiple-choice items via Quizizz), and interview guidelines. Data were analyzed using descriptive statistics, normality test (Kolmogorov-Smirnov/Shapiro-Wilk), homogeneity test (Levene’s test), Independent Sample t-Test, and N-Gain score. Expected Findings: Based on the theoretical framework and relevant prior research, it is hypothesized that the PBL model assisted by Quizizz media will have a significant positive effect on IPAS learning outcomes, demonstrate greater effectiveness in increasing motivation and cognitive learning outcomes compared to conventional methods, and produce a statistically significant difference in post-test scores between the experimental and control groups. Conclusion: The PBL model assisted by Quizizz media is projected to be a contextually relevant, effective, and innovative approach to improving IPAS learning outcomes in the local cultural context of Sanggau Regency, providing empirical evidence to support its broader adoption in elementary social and science education in Indonesia.
