This condition was indicated by students' lack of initiative in learning, dependence on teachers, and limited ability to understand concepts in depth. Therefore, a learning model that can create an active, interactive, and enjoyable learning environment is needed, one of which is the Game Based Learning (GBL) model assisted by QuizWhizzer. This study aims to examine the effectiveness of the Game Based Learning (GBL) model assisted by QuizWhizzer on the learning independence and Social Studies conceptual understanding of fourth-grade students. This study employed a quantitative approach with a quasi-experimental method. The population consisted of all fourth-grade students, with a sample of 50 students. Data were collected using a validated learning independence questionnaire and a conceptual understanding test. Data analysis was conducted using normality tests, homogeneity tests, an independent samples t-test, and an N-gain test. The results showed that: first, the Game Based Learning (GBL) model assisted by QuizWhizzer was moderately effective in improving students' learning independence, as indicated by a Sig. (2-tailed) value of < 0.001 and an N-gain score of 60.71%. Second, the Game Based Learning (GBL) model assisted by QuizWhizzer was moderately effective in improving students' Social Studies conceptual understanding, as indicated by a Sig. (2-tailed) value of < 0.001 and an N-gain score of 61.17%. Thus, the Game Based Learning (GBL) model assisted by QuizWhizzer was moderately effective in improving the learning independence and Social Studies conceptual understanding of fourth-grade students.371.36 Metode Pengajaran, Metode Pembelajaran2026-08-13UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS ILMU TARBIYAH DAN KEGURUANThesis
