This article features Khan Academy which offers an online math program and short video lectures embedded in the "module", or math concept, that fit students' goals. By now, more than 1 million people have watched the online video in which Salman Khan--a charming MIT math whiz, Harvard Business School graduate, and former Boston hedge-fund analyst--explains how he began tutoring his New Orleans cousins in math by posting short lessons for them on YouTube. In November 2010, Los Altos agreed to pilot Khan Academy with two classes of 5th graders and two classes of 7th graders and provide Khan with feedback to refine the web site and tools. By summer 2011, some 250 school districts, charter schools, and independent schools were asking to be part of the pilot--Khan chose only a dozen--and have Khan staff work with them to integrate the videos, data dashboard, and other tools into their math curriculum. Test results at both Los Altos and Oakland's Envision Academy of Arts and Technology--the only two pilots to have any results so far--suggest that Khan Academy is working.
