Abstract
The study aims to analyze the effect of the Discovery Learning model assisted by the interactive media Quizizz on students' critical thinking skills in mathematics at SMK Swasta Al-Ma'shum Sidodadi. The main background of this study is the low level of students' critical thinking skills in solving complex problems. The research method used was a quasi-experimental design with a nonequivalent control group design. The research sample consisted of the experimental class (Xth-2) implementing the Discovery Learning model assisted by Quizizz and the control class (Xth-1) using direct learning. Data were collected through a critical thinking skills test in the form of essay questions measuring indicators of interpretation, analysis, evaluation, and inference. The results of the data analysis showed a significant increase in the average critical thinking skills in the experimental class (80.65) compared to the control class (66.41). Hypothesis testing using an Independent Samples T-Test in SPSS 20 yielded a significance value of 0.000 < 0.05. These findings confirm that the integration of the discovery learning model with the Quizizz gamification media has a significant positive impact on improving students' critical thinking skills.
