Document Camera Research and A Version of an Opaque Projector

http://farm1.static.flickr.com/44/110851360_6d785fd811_m.jpg

According to The Journal June 2007, the document camera is the new hot technology. For you younger teachers, this technology in a bulker form existed many many many years ago. It was called an opaque projector. Teachers could put an object, a picture, an article, or a book on it and it would project the object to a huge size. We used it for a myriad of classroom activities from science comparisons to looking at students’ writing. I found a 1964 article on the opaque projector “The opaque projector as used in a kindergarten and first grade”

Do we have information on what the advantages and disadvantage of the opaque project were in class? Do we have “best practices” for using the opaque projector? Or we are starting from scratch in our use of the document camera? If so, why? I thought we were in the age of “scientific-based research”? Why do we get “hype” and not research? Why cannot we instantly start to use the document camera for greater student learning instead of going through the trail and tribulation stage?

Smartphones over Tablets February 9, 2013

Students do not always carry their tablets with them. For example, Mary may not take her tablet to swim practice but she will have her smartphone with her. Just […]
