The "Elmo Document Camera" is considered a great teaching resource by many (so it seems). There are many websites which offer the documentation camera, including school outfitters and elmousa. There are several different types of cameras and projectors offered.
Unlike the projectors of old, these cameras have HDMI input, USB port, attachment lenses, and image mate software. Not all the cameras offer these features. Some seem pretty basic, such as the P30S (which has USB and is SD card ready). The P30S the basic projector, for moving and still images. For those who just want to go extremely basic (as if any of these are truly a basic projector), the Notebook Digital Document Camera is the way to go.
One of the best things about all these cameras is, they may be one of the most useful classroom tools a teacher can have. Teachers do not always have access to a computer, but this technology allows teachers to present information. There is even a new one which can record student's understanding of the presentation. All adjustments (color, zoom, etc.) can be made by remote control. Images can be shown in singles or in panels, and the educator can choose to click to the image or set a timer, and the camera can be connected through computer or directly to a projector.
This item could be useful for story telling, timeline, focusing in on objects such as rocks and minerals, viewing maps, math problems, flash cards, test reviews, quizzes, tests, or student presentations. The projector can be used on a white board for students to write on during lessons. It can also reduce the amount of words a teacher has to write during a lesson, giving her time to focus on teaching rather than writing and teaching. Most of all, Visual and kinesthetic learners can benefit greatly from this technology.
The only negative might be, learning how to use and apply this technology. However, that's not really a reason not to try it. The other negative may be, the school might not always have these in the classroom. The camera might have to be checked out from the library.
Even so, using this type of technology can be great for the whole classroom. Just doing simple lessons with the projector can be helpful to students and educators. Despite the negatives, it is a piece of technology that should be introduced and used.
