Interesting to notice that there is still this common belief among people that if it is online and it shows in Google, you can use it! No problem with copyright, whatsoever.
I'm glad, though, that more and more, as part of a movement towards digital literacy, Creative Commons is becoming more of a common word. At least, that's what we try to do, make students and educators conscious of the importance of giving credit to the author of an artifact. Not an easy task, but each one of us who learn about it, should tell it at least to another person initiating a movement pro-Creative Commons. Is there an easy and more professional-look than Flickr Creative Commons? Flickr is, by far, my favorite place to search for Creative Commons licensed photos.
Funny that I've been writing about it in the eTutors course at Casa Thomas Jefferson, and I just came across two wonderful resources to take presentations to another level:
Sheryll Terrel's post http://teacherbootcamp.edublogs.org/2010/11/14/creative-common-high-resolution-images-on-flickr/
and this very informative presentation by Esther Wojicicki:
Creative Commons: How to Spread Your Ideas Using CC Licenses
View more presentations from Palo Alto High, Creative Commons, Hewlett Foundation.
By the way, this is a presentation in the Global Education Conference, worth taking a peak!
So, the next time you present, go for Creative Commons and spread the word about it.
