<![CDATA[This research is a quantitative research that aims to determine the effect of the case-based learning model on the learning outcomes of Pancasila education students about norms in my life in grade V of Sikumana 1 Public Elementary School. This research uses the Pre-Experimental Design method with the form of One Group Pretest-Posttest Design. The population and sample in this study were all 21 students of grade VB of Sikumana 1 Public Elementary School in the 2025/2026 academic year. The sampling technique used simple random sampling. Data collection techniques were carried out through tests and documentation with instruments in the form of pretest and posttest questions totaling 20 multiple choice items that have been validated by experts. The results of the reliability test using Cronbach Alpha showed a value of 0.968 with high criteria. The results showed that the pretest and posttest data were normally distributed with a significance value of 0.133 and 0.244 (> 0.05), and homogeneous with a significance value of 0.067 (> 0.05). The results of the hypothesis test using the Paired Sample T-Test showed a significance value (2-tailed) of 0.001 (<0.05), indicating a significant difference between learning outcomes before and after treatment. The average pretest score of 66.43 increased to 87.62 in the posttest. The effect size calculation using Cohen's d was 2.84, which is considered very large. Therefore, it can be concluded that the use of the case-based learning model has a significant and very effective effect on improving student learning outcomes.
