Implementation of Case Based Learning Model on Vibration and Wave Materials on Student's Cognitivie Learning Outcomes of Grade VIII SMPN 7 Pekanbaru

Abstract

This research further emphasizes the contribution of the Case Based Learning (CBL) model in improving students’ cognitive learning outcomes on vibration and wave materials in grade VIII of SMPN 7 Pekanbaru. The implementation of the CBL model was designed to provide students with real-life cases related to vibrations and waves, encouraging them to analyze, discuss, and solve problems collaboratively. Through this process, students were actively engaged in constructing their knowledge, which led to better conceptual understanding compared to conventional learning that tends to be more teacher-centered. The analysis of the results indicates that the experimental group that received treatment using the CBL model not only achieved a higher average score (73.13) compared to the control group (61.87) but also showed greater improvement in critical thinking and problem-solving abilities. This suggests that CBL creates meaningful learning experiences by linking abstract physical concepts with practical applications, which is essential for enhancing students’ long-term retention and comprehension. Furthermore, the significance test confirmed that the difference in learning outcomes between the experimental and control classes was statistically significant, validating the effectiveness of the CBL approach. These findings imply that CBL is not only an effective alternative learning model for improving cognitive outcomes but also a pedagogical strategy that supports the development of higher-order thinking skills (HOTS) among junior high school students. In conclusion, the implementation of the Case Based Learning model on vibration and wave materials has proven to positively influence students’ cognitive learning achievements. This model can serve as a recommendation for teachers to foster more student-centered learning environments and to integrate problem-solving strategies that relate scientific concepts to real-world contexts. The study highlights the potential of CBL to be widely applied in science education as a means to cultivate more effective, engaging, and impactful learning processes in the classroom.
