Classroom clickers and iPods get most of the news-media attention, but document cameras could be the next tech tools to become classroom must-haves, writes Susan Brooks-Young in T.H.E. Journal.
The cameras resemble overhead projectors for the digital era: The devices can display documents and three-dimensional objects on projection screens, televisions, or computer monitors,. Some models, Ms. Brooks-Young writes, even let people freeze and annotate captured images.
Since the cameras are fairly easy for teachers and students to use, plenty of schools are starting to buy them in bulk, and at least a few colleges seem to be following suit. (Thanks to The Kept-Up Academic Librarian for the link.) —Brock Read
