Reflections Chapter 3 - How can the cost of digital devices be justified when the functions they perform are so limited in number and scope?

Digital devices may have limited function, but their are may ways the functions they do have can be used. Most digital devices work with other technology over a five- to seven- year spread, this means they will work with older or newer computers and extends their value. Digital Media Players have many educational uses, that allow students to have easy access to digital and video files through internet interface much like iTunes. Digital Cameras give students to have an interactive and creative way to create presentations.  Personal response systems, much like used on trivia game shows, give teachers the ability to poll students while teaching to measure understanding of topics. All these digital devised provide easy ways to send and receive data. So although they may have limited function they can be used in many ways. They have huge educational value.
