I think Flickr, or any other image program, would be great to use in a classroom. In the reading by Will Richardson, he mentioned that Flickr is an easy place for teachers and students to experiment with not only creating, but publishing content other than text. I think this is true and I like this idea. I feel like students only practice with technology when it deals with writing/typing, so we should change things up a bit and let students practice with pictures.
Flickr would be a great way to let parents see what is going on in the classroom. The teacher could take pictures of students projects or just every day activities and upload them onto the website for parents to look at and share comments. It would be a great way for parents to have a sense of what is going on in their children’s class.

Lots of writing teachers use Flickr as a source for story-starters and creative writing exercises. Depending upon your desired content/age level, you may be able to use Flickr for other innovative projects as well.
