The Science of Accelerated Learning: How Spaced Repetition Changes Everything

Psychologist Hermann Ebbinghaus established the "Forgetting Curve" in the late 19th century. His experiments revealed that without intervention, we forget approximately 50% of what we learn within one hour, 70% by the end of the day, and 90% within a week.

Spaced repetition is the specific technique to counteract this. Instead of reviewing information all at once (massed practice), it breaks learning into intervals: 1 day, 3 days, 1 week, 1 month. Each review strengthens the neural pathway, shifting the curve downward. When you review at the optimal moment—just as you are about to forget—you maximize retention with minimal cognitive load.

Implementing this in a traditional MOOC is difficult because the pacing is usually self-directed and rigid. Launchly solves this through our cohort-based structure. We don't just release a video; we release a module with a specific deadline.

Our system is built on micro-assessments. After learning a concept, you cannot proceed to the next lecture until you demonstrate competency on a spaced quiz. This ensures that the information moves from short-term to long-term memory before the next concept is introduced. The cohort creates a social rhythm that reinforces the scientific rhythm.
