After how many minutes of passive learning do students generally begin to lose focus?

Research in educational psychology indicates that passive learning, where information is delivered without interactive engagement, tends to result in decreased focus after a certain period. Studies often suggest that students typically maintain attention for about 15 to 20 minutes during lectures or presentations. This time frame is critical as it suggests that after 15 to 20 minutes, the brain's ability to retain information diminishes significantly.

In practice, this reinforces the importance of incorporating interactive elements into teaching methods, such as discussions, questions, or activities, to re-engage students and enhance retention. While some may argue for shorter or longer attention spans, the consensus tends to center around this 15 to 20-minute mark as a guideline for effective teaching practices.
