Utilizing Quizizz to Enhance Formative Assessment in the Classroom

The purpose of this study was to investigate the effectiveness of Quizizz as a formative assessment tool in improving student learning outcomes, motivation, and classroom engagement. This study used a mixed-methods approach with a quasi-experimental design, involving ninth-grade students from UPT SMP Negeri 4 Tamalatea during the 2024–2025 academic year. A total of 35 students were selected through purposive sampling and divided into two groups: an experimental class (19 students) using Quizizz and a control class (16 students) using traditional paper-based assessments. Data were collected through pre-tests and post-tests, student questionnaires, classroom observations, and interviews with teachers and students. Quantitative results showed that the experimental group experienced significant improvements in learning outcomes. The average score of the pre-test in the experimental class was 47.63, which increased to 62.63 on the post-test, while the control class only increased from 37.50 to 46.81. The results of the paired sample t-test showed a significant difference in scores (p < 0.05), and further regression analysis confirmed that motivation and engagement had a significant influence on the effectiveness of Quizizz-based assessment (sig = 0.001). Qualitative findings supported these results, revealing that students found the platform fun, motivating, and supportive of collaborative learning. The study concluded that the use of Quizizz as a formative assessment tool significantly improved student learning outcomes and fostered a more engaging and motivating classroom environment.
