I recently signed up to take a free online course, Human-Computer Interaction, through Stanford University. While I already have my master’s degree in HCI, I thought it would be a fun way to stay engaged and gain new insights into the field. That it was free certainly didn’t hurt. Unfortunately, I’m still waiting for the course to get off the ground—what was originally a January start date, was pushed back to March and has now been shelved as “under-development.” I’m still on the mailing list and hopeful that the course will be offered soon.

In this month’s Wired, writer Steven Leckart chronicles his experience taking another free Stanford University online course. This course, CS221: Introduction to Artificial Intelligence, was taught by Sebastian Thrun and Peter Norvig, and what started as an experiment of providing the course free to whomever wanted to take it quickly turned into something else—an astonishing 160,000 students signed up.

In both cases, the aim of these courses is to make learning accessible and free, opening up opportunities those who might not otherwise have them.  Coursera, the site the HCI course is offered through has several other courses available from Stanford University, the University of Michigan and the University of California–Berkley. While Thrun is spinning his course into a new company, Udacity devoted to creating a new education institution made entirely of free online courses, Massachusetts Institute of Technology is also currently exploring this concept with their own initiative MITx set to launch in Fall 2012.

How these courses and programs will affect the future of online learning, we can’t know, but it does bring up some interesting ideas. I’m not suggesting that DePaul should start offering free online classes, but I do think it will be interesting to watch as these programs evolve and expand. I think it’s important that as a university we keep track of our “competition.”
