This study aims to analyze the effect of the Creative Problem Solving (CPS) learning model on students’ creative thinking skills in sound wave material. This research employed a quasi-experimental method using a post-test only control group design. The study was conducted in the second semester of the 2025/2026 academic year at SMAN 15 Pekanbaru. The population consisted of 145 eleventh-grade students, while the sample included two classes selected using simple random sampling, namely the experimental class (38 students) and the control class (35 students). The method involved the implementation of the CPS model in the experimental class and conventional learning in the control class. Data were collected using an essay-based creative thinking test. The results showed that the average creative thinking score of students in the experimental class was 2.89 (categorized as creative), which was higher than that of the control class with a score of 2.34 (categorized as moderately creative). The Independent Sample t-test revealed a significance value of less than 0.05, indicating a significant difference between the two groups. In conclusion, the Creative Problem Solving (CPS) learning model is effective in improving students’ creative thinking skills in sound wave learning.
