The experimental class using PBL and PhET Colorado achieved a science skills proficiency rate of 79.41%, while the control group only reached 39.16%.
This study utilized a quasi-experimental design with pretest-posttest control groups to assess the impact of PBL on seventh-grade students.
The results indicate that employing PBL with PhET Colorado media may effectively enhance students' learning outcomes and science process skills.
