Quasi-experimental study shows STEM-PjBL enhances problem solving in alternative energy materials among students, suggesting effective teaching strategies.
Key Points
STEM-PjBL learning significantly improves problem solving skills in students compared to traditional approaches.
The experimental class exhibited an N-Gain of 0.65, while the control class showed an N-Gain of 0.44, demonstrating better outcomes.
A quasi-experimental design with a non-equivalent control group was employed to assess the effectiveness of the intervention.
These findings indicate that STEM-PjBL can be a vital educational approach at high school levels.
