This study aims to determine the effect of the RADEC (Read, Answer, Discuss, Explain, Create) learning model supported by Quizlet on students’ cognitive learning outcomes in Earth and Solar System material. The RADEC model emphasizes a structured learning sequence that stimulates students to actively read, answer comprehension questions, engage in group discussions, explain concepts, and finally create new products or representations of their knowledge. The integration of Quizlet as a digital learning tool is expected to strengthen this process by providing interactive learning features such as flashcards, quizzes, and games that increase motivation and engagement. The research employs a quasi-experimental design with a non-equivalent post-test control group. The population of this study is seventh-grade students of SMP Negeri 4 Pekanbaru, with two classes selected as samples: one experimental class using the RADEC model with Quizlet and one control class using conventional learning. The instrument applied is a cognitive test developed based on Bloom’s Taxonomy (C1–C6). Data were analyzed descriptively to compare mean scores and inferentially using an independent t-test to examine statistical significance. The findings show that the average score of the experimental class (82.13) is significantly higher than the control class (68.6), with a p-value of 0.000 < 0.05. These results indicate that the RADEC model supported by Quizlet is effective in enhancing students’ cognitive outcomes, particularly in higher-order thinking indicators such as analyzing and creating. The interactive nature of Quizlet not only reinforces students’ comprehension but also fosters independent learning and collaboration. In conclusion, the combination of RADEC learning with Quizlet provides a promising alternative learning strategy in science education. This approach not only improves cognitive achievement but also cultivates active participation, digital literacy, and creativity among students. Therefore, this model is recommended for broader implementation to optimize learning outcomes in Earth and Solar System topics and potentially in other areas of science education
