On Wednesday, free online tutorial service Khan Academy will launch a new series of instructional videos covering the field of computer science.
Shantanu Sinha, Khan Academy president and COO, called the curriculum "pure magic," in another Twitter message.
Backed by ads as well as donations by Google and the Bill and Melinda Gates Foundation, the not-for-profit Khan Academy offers over 3,300 short instructional videos on basic math, biology, chemistry, physics and other subjects. The videos have been praised for how they explain complicated ideas in small, easily understandable chunks. The organization's roots are in videos that Salman Khan created and posted on YouTube starting in 2006 as part of his efforts to tutor some young cousins in math.
Since its incorporation as a nonprofit in 2008, Khan has grown to be one of the most popular self-paced online schools. The organization's YouTube channel has attracted 370,000 subscribers and over 174 million video views. The videos are organized so that users can systematically learn an entire subject, such as trigonometry or calculus. The organization also provides statistics, badges and suggested paths of learning to further motivate users.
While Khan has created a lot of good will among its users, observers of higher education caution at the limits of the organization's video-based approach.
"Khan Academy is great for learning about lots of different subjects. But it's not really adequate for learning those subjects on a level that really makes a difference in the world," wrote Robert Talbert, a mathematics professor at Grand Valley State University,in a widely discussed blog post on the Chronicle of Higher Education Web site.
Neither Resig nor Khan Academy immediately responded to requests for comment.
