Teachers keep reinventing-the-wheel. Openoffice is taught over and over
again, not only in formal educaiton, but also in non-profits and in
for-profit companies. My website's goal is to collect tutorials that can be
used in place of reinventing-the-wheel.
I agree that having a central repository of teaching resources is a good
idea. One of the big stumbling blocks we've been having with using
Manhattan vs. WebCT is the lack of content exchange and re-usable
material available to teachers. I wonder if there are other sites out
there with 'open' material that you could use to populate your own site
with.
