ABSTRACT
Creative thinking ability is a cognitive activity or thought process that enables individuals to generate new and beneficial ideas. One instructional model that can be implemented to develop students' creative thinking skills is the Project-Based Learning (PjBL) model. This study aims to apply the Project-Based Learning (PjBL) model to enhance the creative thinking skills of eighth-grade students on the topic of the human excretory system. The research method used a Pre-Experimental design with a One-Group Pretest-Posttest approach. The subjects of the study consisted of 24 eighth-grade students from SMP State 1 Bulawa Junior High School. Data collection techniques included written tests, observations, and student response questionnaires, analyzed using a quantitative descriptive approach. The results indicate that the implementation of the learning model achieved an average percentage of 92%, categorized as very good. Student activity obtained an average percentage of 65%, categorized as fairly good. Student responses reached an average percentage of 88%, categorized as very good. The overall pretest results showed an average percentage of 50%, categorized as less creative, while the posttest results demonstrated an average percentage of 88%, categorized as creative. Additionally, the average percentage of product scores from each group was 77%, categorized as creative. Therefore, it can be concluded that the implementation of the Project-Based Learning model in the human excretory system topic was successfully conducted and had a positive impact on students' creative thinking skills in the eighth grade of SMP State 1 Bulawa Junior High School.
