Which concept relates to the effectiveness of educational techniques over time?

The effectiveness of educational techniques over time is best captured by the concept of distributed practice. This technique involves spreading out learning sessions over time rather than cramming information in a short period. Research consistently shows that learning is more durable and long-lasting when distributed across multiple sessions, allowing for better retention of information and a deeper understanding of the material.

Alternatively, massed practice involves learning a large amount of material in a single session, which often leads to quick forgetting and superficial learning. Reinforced learning, while important, focuses more on the reinforcement of previously learned material rather than the method or scheduling of study sessions. Cognitive rehearsal refers to the mental practice of skills or material, but it does not specifically address how learning effectiveness can be enhanced over time through proper timing and spaced intervals.
