There is a website www.informationliteracy.org that has compiled IL lesson plans for all age groups. There a few well designed lessons for first year college students that offer interesting ideas for making lessons more student-centered. One in particular uses playing cards to demonstrate how using AND or OR will change your search results - it sounds kind of fun!
There is also a tool called BuILder - to create web-based lessons which in my undergrad days were called "webquests". I created a short lesson to teach the Periodical Locator just to see how it works. Click here if you want to check it out. The program is a bit clunky to use and it took me about 3 hours to develop this one lesson, but I like the idea behind it. It's the kind of thing you could use to break up a long lesson of lecture by giving the students something to learn on their own. There is probably opportunity to create similar lessons using NetOp features - I just haven't figured them all out yet! I'll keep you posted.
The site also has a section of Teaching Ideas, which are not fully developed lessons but brief ideas for instruction.
