Implementation of STEM-Based PBL with Quizizz and Mentimeter Media on Student Learning Outcomes

Abstract

An effective learning model and appropriate media are essential to optimize students’ understanding and learning outcomes. This study aims to find out if there are differences in student learning results when using the Problem-Based Learning STEM model with Quizizz media compared to Mentimeter media. This study uses a quantitative method with an experimental design and a sample selected through random sampling, consisting of two experimental groups taught using the STEM-based Problem-Based Learning model with different media, namely Quizizz and Mentimeter. The research instrument is a validated multiple-choice learning outcome test, and the data are analyzed using normality and homogeneity tests, as well as hypothesis testing with paired sample t-test andindependent t-test. The paired sample t-test results showed a significant improvement in learning outcomes before and after the treatment in both classes (significance 0.000 ≤ 0.05), while the independent t-test results indicated a significant difference in learning outcomes between the two experimental classes (significance 0.000 ≤ 0.05). The implementation of the STEM-based ProblemBased Learning model with the help of digital learning media (Quizizz and Mentimeter) is effective in improving students' learning outcomes on stoichiometry material; however, Quizizz proved to be superior to Mentimeter in this study.
