Improving Students' Understanding of Chemistry Concepts and Environmental Sensitivity through the Implementation of the Project-Based Learning (PJBL) Model Based on the Socio-Scientific Issue (SSI) Approach

Increasingly complex environmental problems require education that fosters students' scientific sensitivity and understanding. This study aims to improve students' understanding of chemical concepts and environmental sensitivity through the application of a Project-Based Learning model based on Socio-Scientific Issues. The method used was a quasi-experimental design with a non-equivalent control group, implemented for one semester in Chemistry Education students. The results showed a significant increase in conceptual understanding and environmental awareness. Contextual project-based learning has been proven to integrate science with real social issues. In conclusion, this approach is effective and feasible to be implemented as a transformative learning strategy in higher education.
