Having checked out the 12 Essentials for Integrating technology posted by Free tech for teachers(both links are on the side bar), I did a little test run of animoto, a service that allows you to create presentations from your photos and video clips. Easy, but not as quick as advertised. It took a little while for the video to be rendered and sent to my email account, however that is my only minor complaint.
I literally thru together a bunch of photos from a field trip I did with my grade sixes, and voila! I have a cool little memento of the trip. Check out the above link.
In terms of applications for teachers, we take a lot of photos at our school, so it would be easy for me to assign a photo essay type project as a HW assignment to sum up an activity, have them share it on our blog. I’m sure with more thought I could come up with lots of other applications for it.
