The Science of Spaced Repetition

Have you ever wondered why some learning methods work better than others? The secret lies in understanding how our brains naturally process and store information.

What is Spaced Repetition?

Spaced repetition is a learning technique that involves reviewing information at increasing intervals over time. Instead of cramming, you revisit material just as you’re about to forget it.

The Forgetting Curve

German psychologist Hermann Ebbinghaus discovered the “forgetting curve” in 1885. His research showed that:

• After 1 day, we forget about 70% of new information
• The rate of forgetting slows over time
• Each review strengthens memory and extends retention

How QuizFerret Implements It

Our algorithm tracks your performance on every quiz and automatically:

1. Identifies weak spots - Words you struggle with appear more frequently
2. Reinforces mastery - Successfully recalled words are reviewed at longer intervals
3. Optimizes timing - Reviews are scheduled just before predicted forgetting

Real Results

Users who practice consistently with spaced repetition:

• Retain 80% more vocabulary after 6 months
• Achieve fluency 2x faster than traditional methods
• Report higher confidence in real conversations
