What is it about?
This study investigates whether teachers turning on their webcams in online classes helps or hinders students’ learning. Using lab experiments with eye-tracking and brainwave measurements, the researchers found that having the teacher’s camera on can sometimes distract students and reduce focus on lesson content. However, a strong sense of social presence—the feeling of connection in a virtual classroom—can balance these effects and improve memorisation. The findings suggest that online teaching strategies should carefully consider when and how webcams are used.

Why is it important?
This work is unique because it combines neuroscience tools with educational research, offering objective evidence on how students focus and remember. The findings are timely in a world where online learning continues to grow. By showing the importance of social presence, the study provides valuable guidance for designing online classes that are both engaging and effective.
Perspectives
From my point of view, this research shows that “human connection” is as important online as it is in face-to-face classrooms. Technology alone doesn’t guarantee learning—it’s the way teachers use it that makes the difference. The takeaway is that educators should blend technical tools with strategies that foster community and interaction.
