Although I am a librarian, I am also something of an educational technologist here, for lack of a better term. I keep track of technology that is developing and try to connect it to classes and instructors here.
I realized that I could promote the use of Pinterest to our Education students. I see plenty of our students on Pinterest already, but there is a small learning curve to using it effectively. So I contacted our Education Student Club and arranged to do a little show & tell. They took care of booking a room with a computer podium, and all the students brought in their laptops.
The first question I asked the group was to see how many of them had Pinterest accounts already. 100% of them did. My fear of telling them information they already knew was unfounded. The whole presentation was peppered with comments of surprise, realization, and understanding.
I have loaded my talk on SlideShare. Be sure to read the notes on each slide, as I made an effort to share the key points of my talk there.
