The Impact of Project-Based Learning (PjBL) Model on Secondary Students’ Creative Thinking Skills

This is the authors' abstract. We don't add key points for this paper.

This study aims to identify the impact of using the project-based learning (PjBL) model compared to the direct instruction learning model on secondary school students' creative thinking (CT) skills. Quasi-experimental with pretest-posttest control group design was carried out to achieve the research objectives. Fifty secondary school students randomly chosen as experimental group (n = 25) and control group (n = 25) participated in the study. Eight essay tests were used to collect students' CT based on fluency, flexibility, originality, and elaboration indicators. Data were analyzed descriptively (n-gain) and statistically using paired t-test and independent sample t-test. The result shows that students' CT significantly improved after learning for the experimental group (n-gain = 0.47; p < 0.05) and the control group (n-gain = 0.25; p < 0.05). However, students' CT in the experimental group was significantly different compared to the control group achievement (p < 0.05). Thus, the conclusion proposed that the PjBL model significantly impacts secondary school students' CT skills on the temperature and expansion material.
