I'm not sure where you're located... If not in N. America, you may not be familiar with a program put out by League for Innovation (www.league.org) called "LENs", or Learning Exchange Networks. It's predominantly U.S. based, but one of our local community colleges (Humber, in Toronto) was a member of the consortium that developed the materials. My predecessor researched options and determined this would be one of the best available, and when I took over the position on campus, I just kept the status quo, as it had garnered such a strong response.
The content is meant to be delivered in six modules, but I only cover three per semester and I take two afternoons to cover each; hence the 12 sessions in total. Our sessions are three hours. It's a terrific set of materials, if you ask me, and I have yet to come across anything that decidedly surpasses the quality. It feels very much like an 'add water and stir' kind of formula. I freshen it up every year by changing some of the activities, and we bring in our in-house experts on a variety of topics - anything from rubrics to technology in the classroom, etc - but generally the content is rock solid and easy to use. I mean, REALLY easy.
We haven't gone so far as to collect data that goes beyond your usual feedback form, but I'd say that the LENs sessions (as they've become known) are probably considered the hallmark of what comes out of my office, though I do a lot more.... And they are widely well regarded.
As a community college, our faculty are members of a union, and in some respects that actually makes life easier. Their participation in the sessions is a condition of employment when they're hired on. People who have been with us since before the establishment of this program still opt in for reasons I described earlier. I think they stay pretty willingly. :)
I wasn't aware of the League for Innovation (www.league.org) "LENs" Learning Exchange Networks modules. We have been developing and offering something similar without knowing this existed. Arrgg!
This is especially frustrating when our district is very active in the League. We, Foothill-DeAnza College District - are the "host" for the League for Innovation conference next week! I'm going as a volunteer, so I'll be on the look-out for more information.
BTW: Is anyone else going to the League for Innovation conference (www.league.org/i2009/) in Reno Nevada next week? I'll be there Sunday Mar 15 - Wed Mar 18. I'd love to meet up with fellow SCoPE-ers.
