Spaced practice significantly improves second language learning with specific patterns for long-term memory

In short: A meta-analysis of 48 experiments involving 3,411 participants found that spacing out practice sessions has a medium-to-large positive effect on learning a second language. The research compared different methods of timing, such as massed versus spaced practice and varying the length and consistency of those intervals.

The study highlights that while shorter intervals are just as effective as longer ones for immediate recall, longer spacing is superior for retaining information over time. Additionally, researchers found no significant difference between using equal intervals or expanding them as practice progresses.

This meta-analysis synthesized 98 effect sizes from previous experiments to identify broad trends. However, the variability in results across different studies was influenced by several factors, including the specific learning target, the number of sessions, and the type of activity performed.

Why it matters: To remember a new language longer, it is better to space out your practice over time rather than cramming.
