Disruptive innovation in the lecture theatre

The Economist:

DROPPING out of university to launch a start-up is old hat. The twist with Joseph Cohen, Dan Getelman and Jim Grandpre is that their start-up aims to improve how universities work. In May 2011 the three founders quit the University of Pennsylvania to launch Coursekit, soon rebranded as Lore, which has already raised $6m to develop what Mr Cohen, its 21-year-old chief executive, describes as a “social-learning network for the classroom”.
Lore is part of a trend that builds on the familiarity with social networking that has come with the success of Facebook. It customises the rules of a network to meet the specific needs of students. Anyone teaching a class would reasonably worry that students using Facebook were gossiping rather than learning useful information from their network of friends. Lore allows teachers to control exactly who is in the network (by issuing a class-membership code) and to see how they are using it. They can also distribute course materials, contact students, manage tests and grades, and decide what to make public and what to keep private. Students can also interact with each other.
