Mathigon – an interactive, personalized mathematics textbook
It really feels like we're on the cusp of a textbook similar to the Primer in Neal Stephenson's 'The Diamond Age: Or, A Young Lady's Illustrated Primer'.<p>As in, something that learns your interests and customizes to your tastes while still teaching.  A textbook that is able to diagnose common misunderstandings from a set of wrong answers to a problem set and evolve its teaching methods.<p>If advertising networks have effectively personalized propaganda on Facebook and whatnot and games like The Walking Dead are able to change script based on popular choices made by all players, we should be able to apply the same technology to personalized learning at scale.
