We've all heard that technology will change education as we know it. But many next-big-things introduced in recent years have failed to live up to that potential. In his recent book The World Is Open: How Web Technology Is Revolutionizing Education, Curtis Bonk argues that what has been missing is convergence. Bonk outlines 10 technology trends that, when combined in whole or in part, can transform learning. And, Bonk notes, it is likely that something entirely new will result from the mix. But while he enthuses about possibilities, he’s also cautious. Spontaneous use of emergent technology, or the inclusion of a new tool just because it is a sexy thing to do, will not bring about positive change in learning, he says.
