Online learning cannot replace the social and emotional growth that happens in a physical classroom. I've taught high school for nine years, and the shift to remote classes in 2020 made me realize how much students lose when they're not sitting next to peers—debating ideas, reading body language, or just laughing during lunch break. Even with better platforms and interactive tools now, the lack of spontaneous human connection is a gap that no video call can fill, especially for teenagers who are still developing social skills.
