Projectors: The Big Picture
Gamble-Risley, Michelle
T.H.E. Journal, v33 n10 p24-32 May 2006
In the past, projection systems were large, heavy, and unwieldy and cost $3,000 to $5,000. Setup was fraught with the challenges of multiple wires plugged into the backs of desktop computers, often causing confusion about what went where. Systems were sometimes so difficult to set up that teachers had to spend pre-class time putting them together. Now, thanks to new and emerging technologies, the experience of using the projector has been completely transformed. State-of-the-art, lightweight projection systems (some new models weigh as little as five pounds) offer advanced features and capabilities at prices less than $1,000. Many of the latest systems provide plug-and-play setup capabilities, project clear and vibrant colors, include controls for adjusting brightness, and work with wireless laptops to reduce the mess and nuisance of jumbles of tangled wires. These sophisticated systems can now be used by teachers to breathe life into what--in the absence of a projector--would be stagnant, linear, paperbound experiences. This article discusses the projector's value and its potential applications in classrooms. It also provides helpful tips to school districts that are planning to invest in new projection systems.
