It's Show Time: The Latest Projectors, Document Cameras, and Digital Whiteboards Help Educators Make a Good Impression in the Classroom. (Spotlight)

Article excerpt

Presentation technology is a growing product category in the education market, as more and more educators incorporate new tools into their teaching. Digital projectors, document cameras, and interactive whiteboards, in particular, are increasingly being used to help teachers integrate media-rich instruction into classrooms.

Today's digital projectors are smaller, lighter, and more powerful than even just a year ago. Educators can expect to find a unit with SVGA resolution (800 x 600 pixels) or better, and more than 1000 lumens of brightness, for under $2,000. That means teachers can project crisp images of PowerPoint presentations and other media, without having to turn out the lights. Some companies now offer wireless connectivity options, eliminating the need for cables between projector and computer.

While digital projectors are great for showing off 2-D computer graphics or video, document cameras are ideal for projecting 3-D objects, microscopic images, slides, and fine print on documents. This is especially useful in the science classroom, where a biology teacher, for instance, could display detailed images of local flora and fauna.

The electronic, or interactive, whiteboard is another tool putting a high-tech twist on teaching and learning. The technology records what's written on a "smart" whiteboard into a digital file or, conversely, projects electronic files from a computer onto the board. For example, teachers can capture their classroom lecture notes and then post them on a Web site along with links to additional materials. As with digital projectors, some whiteboards now work with Wi-Fi wireless networking technology.

Following are just some of the many presentation hardware tools available for education. For more detailed information on the features of a particular model, be sure to check the company Web site.
