Are computers counterproductive to a child's development?

Wittenberg University education professor and former computer teacher Lowell Monke thinks so, and has written a provocative essay arguing that, among other things, computers render children "less animated and less capable of appreciating what it means to be alive, what it means to belong in the world as a biological, social being," and "teach children a manipulative way of engaging the world.” His polemic is partially supported by evidence (.pdf academic paper; BBC gloss here) indicating that, above a certain threshold, computer use is correlated with lower test scores. The latest salvo in the continuing debate over education and the culture of simulation. [from MetaFilter.com]
