When it comes to choosing between a projector and a flat-panel display, experts advise looking at screen size, viewing angle, life span, and durability. They also suggest doing a total cost of ownership, which includes the price of replacement projector bulbs. Sometimes, though, it’s easier to get the facts from your colleagues. That’s why we asked a couple of teachers to tell us…

Why I Like My Flat-Panel Display…

¦ Students love looking at it. “Every student wants to look at a large and beautiful screen,” says Chris Craft, a sixth-grade Spanish and Latin teacher at CrossRoads Middle School in Columbia, South Carolina. “They are unusual in classrooms, so they’re motivational.”

¦ The diverse input set. Teachers appreciate being able to connect the display to a variety of inputs. “I can hook it up to our computers, to cable, or to our in-house video service to deliver media content,” says Steven Anderson, district instructional technologist at Winston-Salem/Forsyth County Schools in Winston-Salem, North Carolina. “It does a lot more than just display images from a computer. It’s versatile.”

¦ The fantastic sound. “Because the display is mounted, the built-in sound bounces off the wall and fills the room,” Craft says. “When I’m playing a video, every kid can easily hear what’s going on.”

¦ It is user-friendly. “You plug in the computer, hit two buttons, and it’s fired up,” Anderson says.

¦ There are no awkward moments. No matter how close he gets to the display when pointing out content, Craft doesn’t have to be concerned about something projecting onto his back.

¦ It handles high-definition content. “Our digital document cameras have high-definition lenses, so the detail we can see on threedimensional objects and through microscopes is incredible,” says Anderson. ”When viewed through a projector—even ours, which have high lumens levels—there is still a great amount of detail lost. When viewed with our highdefinition flat-panel displays, very little if any detail is lost.”

¦ It makes financial sense. “Three years ago we had 51; now we have more than 60,” Anderson says. “They keep getting bigger, but the cost has stayed the same.”

Why I Dislike My Flat-Panel Display…

¦ The comparatively high initial cost. The up-front cost is higher than that of a projector, according to Anderson. Because of the high price of replacement bulbs, however, a projector costs more in the long run.

¦ It can be hard to see. “It’s a learning process of where and how high to hang them,” Anderson says. “Sometimes the only available wall has sunlight coming in. Projectors can be moved around.”

Why I Like My High-End Projector…

¦ The wand. Craft’s projector has a wand that functions the way a Wii remote does, letting him interact, at a distance, with his board or with content.

¦ The diverse input set. The many inputs include HDMI and VGA.

¦ The terrific projection. Craft’s projector is short throw and can display a large image from a short distance away.

¦ It handles high-definition content. “A lot of good content is being made available in HD,” says Craft. “For example, I use carefully selected YouTube videos that are available in full HD. I can easily embed them into my lesson and play them in full HD.”

¦ Today’s projectors have cool features. Craft loves the moderator feature, which enables him to display the screen from any laptop connected to it (via a network). The narrator feature turns down the video so that he can be heard above it.

Why I Dislike My High-End Projector…

¦ You have to replace the bulb. The life expectancy of the average projector bulb is 2,000 hours. “Bulbs are outrageously expensive—especially the high-end ones, which cost $700 or $800,” Anderson says. “You pay for the projectors five times over because of the bulb replacement.”

Document Camera — Now You See It

Teachers say that document cameras change the way they teach. Because the cameras allow them to place any object under the lens and project it in full color onto a large screen, teachers say, they help them manage the classroom, keep students engaged, and can lead to increased retention.
