1923 -- the promise of radio:The Hertzian waves will carry education as they do music to the backwoods, isolated farms and into the mountains of Tennessee, Kentucky and West Virginia. The limitations of "the little red schoolhouse" will pass away; the country schoolteacher will be reinforced by college professors and other specialists. Radio will be an institution of learning as well as a medium for entertainment and communication. [*New York Times*, February 24, 1923]1941 -- the promise of television:While children may be bored and restless when merely listening to a speaker [on radio] without seeing him, living talent or motion pictures broadcast at a certain time to all schools in a given area will capture and hold their interest.

[Every discussion group on the Net]1999 -- the promise of virtual reality:Why should students be interested in flat-screen interaction with the world?

[MSNBC news item, coincidentally appearing on the release date for Microsoft's new, virtual reality software, "B U, B Me"]2010 -- at the dawn of a new era:The test scores of American students in math, science, reading, and writing continued their long-term decline last year. Some educators have taken consolation in the fact that certain indicators of hand-eye coordination are up. But all are calling for a renewed national commitment to the advanced educational technologies that will prepare our young people for the rest of this century.
