Although our site is dedicated mainly to projectors, and this blog focuses mostly on classroom projectors, we would be remiss if we did not include information on document cameras --especially due to the large number of site visitors who are involved in education or training. I started thinking about document cameras this morning after I forked over nearly $90 for replacement ink cartridges for my printer. Stewing over the expense got me on a train of thinking that led to my local school district, the budget cuts and how this technology can help schools save a dramatic amount of money on paper and photocopying.
Document cameras, also less commonly known as visual presenters digital visualizers, docucams and digital overheads, are real-time image capture devices for displaying an object to a large audience. The best thing about a document camera is that it is quick and easy, making it likely the best way for a newcomer to classroom technology to introduce it into the classroom environment. Aside from the benefits to visual and hands-on learners alike, a document camera can be used to impact copying expenses. For example, rather than creating 60 copies of an exam which uses significant ink and paper, a teacher could simply place the exam on the document camera and allow the students to pull out their own neotebook paper. Better yet, if they use a clicker response system they won't even need any paper at all.
