If you are still using an overhead projector, you need to check about upgrading to a document camera. Document cameras allow a teacher to put anything under the camera for all the class to see. Items can range from a news article to a color photograph. I use mine often as a vehicle for students to share their work with the class. They simply come up to my desk and place their writing under the camera lens. The image appears on my whiteboard and from that point, the entire class can take part in the editing process.
I have linked a site with 50 ideas for using document cameras in your classroom. Another plus is that you can face the class with ease. This makes it possible for you to address student concerns quickly since you are facing them throughout the instructional delivery. Prices? There is a wide range from $300 to $6,000. Mine is about $700 and worth every penny!
What technology do you use in your class? If you had all the money you could ever hope for to use for your classroom/students, what technology would you buy and why?
