Watched a very instructive and inspiring 20 minute video on TED:
http://www.ted.com/talks/daphne_koller_what_we_re_learning_from_online_education.html
Some nice points mentioned in the talk:
From 1985 to 2011, the cost of higher education (college tuition and fees) has had a 559% increase. This is about two and a half times more than the increase in all consumer items, and about one and a half times more than the increase in costs of medical care.
A study published in Science in 2011 titled "Retrieval Practice Produces More Learning than Elaborate Studying with Concept Mapping" by J. Karpicke and J. Blunt concluded that simple retrieval practice is nearly 150% more effective than repeated study without retrieval practice.
Active Learning improves attendance, engagement and learning. Active Learning as opposed to passive lecturing involves more interactions with the students and encouraging them to think and be creative.
The 2 Sigma Problem: Individual Tutoring produces achievement scores which are two standard deviations better than normal classroom lecturing. This is from a study by Benjamin Bloom in 1984.
Apart from these nice points, she gave lots of information about her new venture. Along with her fellow Professor at Stanford - Andrew Ng - she opened an online site called coursera to provide free online courses in collaboration with the top universities from around the world.
What is surprising is that she did not mention coursera's two main competitors:
Udacity founded by Sebastian Thrun and others
edX founded jointly by Harvard and MIT
