Why it works
The protégé effect
Students worked harder to learn material when they were teaching it to a computer agent than when they were learning it for themselves.
Chase, Chin, Oppezzo & Schwartz (2009), Journal of Science Education and Technology
Explaining beats re-reading
Explaining material to others led to better understanding and recall than simply studying it again.
Fiorella & Mayer (2013), Contemporary Educational Psychology
