Can a computer lecture better than a human?

I’m going to prime the pump a little bit for my K12 Online presentation next week…

My fifth-grade daughter’s math homework this weekend required her to find out what a radian or a grad was (hint: both are ways besides degrees to measure angles). We hit ye olde Google and quickly found this helpful (and free) learning activity from Wisconsin Online:


Bam! Ten minutes later my daughter and I had learned what a radian was (the animation was much more helpful than the mere definitions that we found), answered correctly all of the self-assessment questions, and were ready to move forward.

Okay, we actually weren’t ready to move forward because we thought the animation was so cool that we set up a Wisconsin Online account and dug around for other interesting tutorials. In other words, we were passionate, self-directed, engaged learners, prompted by a single question from my daughter’s math book.

I’ve thought about that moment quite a bit the last couple of days. Of course my mind started wandering to the K12 Online Conference, the TED videos, various podcasts, the MIT Open Courseware project, and other similar online multimedia resources. As my mind meandered around, it dug up a question:

Can a computer lecture better than a human?

That question’s not quite accurate, because there’s still a human behind every online learning activity. What I mean is that there are quite a number of examples on the Web of ways that we can learn and assess ourselves on fairly complex material using video lectures, animations, simulations, video games, and the like. As these resources grow in number – fueled by easy-to-learn, increasingly-powerful software that allows average citizens to create learning objects – and are organized and collected by individual experts, organizations like Wisconsin Online, or group efforts, it’s going to become unbelievably easy to find a variety of ways other than text to learn about almost anything we want. This will be especially true if we are intentional about it and actively work to fill in needed gaps.
