Young, J. (2009) Teaching with Twitter: Not for the Faint of Heart Chronicle of Higher Education, November 22
Interesting article on use of Twitter and Hotseat for providing backchat during lecture classes at Purdue University. Also includes a digital video interview with one of the professors using Twitter.
Again, an excellent example of using new technology to re-inforce traditional teaching rather than looking at new delivery methods.
