In case this news has not yet made it into Classroom 2.0,
Jonathon Feinberg who created
Wordle has recently taken several steps to make it safe for classroom use. I quote from his blog:
"I’m happy to announce that from now on, the Wordle front page will never feature images or links that are inappropriate for classroom use. It's now possible to configure an institution's "site-blocking" software to keep Wordle safe for classroom use.
Simply have your networking administrator block the following base URLs (i.e. block all URLs that begin with the given text, and not merely those literal URLs.) :
*
http://www.wordle.net/gallery
*
http://www.wordle.net/next
*
http://www.wordle.net/random
and your users will not see anything that's not safe for classrooms. You’ll still be able to save your work, bookmark your individual Wordle creations, print them out, and share the URLs of saved Wordles with each other and with families.Please let me know whether this works out for you in your school or other institution."
For educational uses of Wordle, you can take a look at my own blog:
Small Changes; BIG RETURNS. I think I may have all the kids in our school list the 5 words they associate with being back in week one and get a couple of them create a word cloud for our school.
