Rapid evolution in e-learning
The software program unleashed in this classroom is the brainchild of Salman Khan, an Ivy League-trained math whiz and the son of an immigrant single mother. Mr. Khan, 35, has become something of an online sensation with his Khan Academy math and science lessons on YouTube, which has attracted up to 3.5 million viewers a month.
Now he wants to weave those digital lessons into the fabric of the school curriculum — a more ambitious and as yet untested proposition.
This semester, at least 36 schools nationwide are trying out Mr. Khan’s experiment: splitting up the work of teaching between man and machine, and combining teacher-led lessons with computer-based lectures and exercises.
