According to the Society for Information Display (SID), the key feature educators consider when purchasing new projectors is image quality. Manufacturers provide resolution, brightness and contrast figures to evaluate performance, but these specifications don’t address color quality. A new metric released by SID, color light output (CLO), will allow educators to evaluate color performance between competing projector models quickly and accurately. CLO or color brightness should be the same as the white brightness or white light output to ensure that images are vibrant.
With a vast number of new software and Web-based reading programs on the market, students of all ages and abilities can target specific reading skills, such as comprehension, fluency, phonemic awareness and vocabulary. In addition, access has changed greatly over the last couple of years. Students no longer need to be in a computer lab to use Web-based programs; they can use laptops or tablets as part of a one-to-one computing program or their own devices if their school has a bring-your-own-device policy.
With over 200,000 applications available for Apple’s iPad and thousands more for Android devices, educators and students must sift through a lot of apps to find effective learning tools. An app is software that allows users to perform specific tasks on a mobile device.
Instantly transform any image or object into digital, interactive content with document cameras, also known as visual presenters. Companies that create these products have come a long way in the last few years, as document cameras are now more compact, mobile and interactive.
While Facebook and Google+ are popular social networks for everyday life, dozens of other networks have been created to provide safe and effective social learning environments for K12 education. Social learning networks (SLNs) allow students to learn 21st-century skills. Students can build online portfolios and resumes and collaborate with peers through project-based learning, which will help them in college or the workforce.
In the last few years, smartphones have moved quickly from banned to embraced in K12 schools as educators have realized that mobile learning devices engage students, enhance the teaching of 21st-century skills, and instantly check for understanding with student response applications. Districts have started upgrading their wireless networks to accommodate one-to-one technology initiatives, while others follow a “bring your own device” (BYOD) policy.
Since the U.S. Green Building Council launched LEED (Leadership in Energy and Environmental Design) for Schools certification in 2007, building sustainable, eco-friendly facilities has become the norm for new construction and is statewide policy in 13 states. However, there is still much to be done with the approximately 99,000 existing public schools across the United States. According to “A National Action Plan for Greening America’s Schools” (Sundance, 2011), on average, green schools save $100,000 per year on operating costs. Over 10 years, America’s schools could save $20 billion.
While today's K12 classrooms use more multimedia than ever before, typically it is the visual technologies—such as projectors, interactive whiteboards and television displays—that receive most of the attention in the marketplace. The audio component is just as important, however, and can often be overlooked. That is rapidly changing, and a number of companies are beginning to design classroom audio systems to meet a growing demand for better sound.
While tablet computers like the iPad get more attention, eBook readers—comparatively simpler devices designed specifically for reading electronic versions of books, magazines and newspapers—are currently selling in greater numbers and at a faster rate than tablets. E-book readers also hold much appeal for education, and for the same reasons they are increasing in popularity with consumers: ever-improving features and growing capabilities for displaying a variety of content, for a fraction of the price of most full-featured tablet PCs.
