VIS employs Project-Based Learning (PBL) as the core teaching methodology across all grades, hosting an annual all-school PBL Spring Exhibition (six editions from 2021 to 2026). PBL emphasizes cross-disciplinary integration, real-world problem-solving, and alignment with the UN's Sustainable Development Goals (SDGs). Students design, build, and implement locally-focused solutions — developing into active learners and global citizens.
