This is a PDF of an important publication challenging the use of technology by young children. It's about eight years old now, but the information in it is more important than ever, as the various standards and pacing guides push technology use down to the lower grades.
Something of a follow-up to the Fool's Gold publication, this document more specifically addresses the idea of "technology literacy". It takes a broader view of tech literacy, encouraging the reader to see it as a social thing, not just the ability to use different kinds of software. It contains a good critique of ISTE. Should be mandatory reading for any tech in education program.
