What study technique involves spreading out learning over multiple sessions to improve retention?

Spaced learning is a study technique that is based on the principle of distributing study sessions over time, rather than cramming all at once into a single session. This approach leverages the spacing effect, which suggests that information is better retained when learning events are spaced apart rather than massed together. By allowing time between study sessions, learners give their brains a chance to consolidate the information, leading to improved long-term retention and recall.

In contrast, rehearsal focuses on repeatedly practicing or going over material without necessarily involving a spread-out study schedule. Cramming involves attempting to learn a large amount of information in a short period, typically leading to lower retention rates and increased stress. Active recall, while highly effective, involves testing oneself on the material rather than focusing on the timing of study sessions. Therefore, the best choice for the technique that emphasizes spreading out learning over time is indeed spaced learning.
