What principle focuses on the best schedule for learning during an event?

The principle that focuses on the best schedule for learning during an event is distributed learning. This approach incorporates the idea of spacing out learning sessions over time rather than cramming information all at once. By distributing learning, participants can better absorb and retain information, which enhances long-term memory and understanding.

Distributed learning is particularly effective because it allows for periodic review of material, enables the learner to make connections across different topics, and accommodates the natural forgetting curve. By spacing out sessions, learners have time to process and apply what they've learned, leading to improved performance and knowledge retention.

In contrast, meaningful engagement refers to strategies that foster active involvement of participants but does not specifically address the timing of learning. Interactive techniques enhance participation and can be crucial for engagement, yet they do not inherently focus on scheduling. Feedback loops are essential for assessing understanding and providing opportunities for reflection, but again, they do not specifically relate to the timing of learning experiences. Thus, distributed learning stands out as the principle that prioritizes the timing and schedule of educational events for optimal learning outcomes.
