School reform with YouTube videos: Khan Academy
In this WSJ piece, Sal Khan, founder of Khan Academy, describes his pilot program in Los Altos, CA schools:
In order to help teachers customize their instruction, [Khan Academy] created a dashboard of robust data for them to follow, linked to their students' online exercises. Students don't move on to more advanced concepts until they have mastered basic ones. Those who get "stuck" promptly receive help, often from peers who are already proficient in a subject. The overall effect has been to create a more collaborative classroom culture.
Khan Academy is one of the most important projects in the world, really worth getting to know if you haven't already. Sal gave a tremendous talk at Gel 2010 last year describing it:
(The next Gel is Gel 2011, coming up on April 28-30.)
Montessori kids from the age of 6 do this as a basic part of their education. Divided into age groups instead of by grade - 3-6 yrs, 6-9, 9-12 etc - the older students are expected to teach the lsssons and works to their younger peers as part of completion and mastery.
