Quasi-experimental design improved critical thinking skills in chemistry students, indicating the PBL model may enhance learning outcomes.
Key Points
The implementation of the PBL model significantly improved critical thinking skills in students, particularly in analysis and inference.
Students in the experimental group saw their average critical thinking score rise from 62.1 to 84.7, while the control group increased from 61.8 to 70.5.
This quasi-experimental study involved chemistry education students from Christian University of Indonesia, assessing their critical thinking abilities.
The findings support broad adoption of the PBL model in higher education to foster better critical thinking development.
