Jared Cooney Horvath warns that expanding educational technology is lowering children’s cognitive abilities.
He notes the U.S. edtech industry is worth $400 bn (£295 bn) versus the UK’s £6.5 bn, that 88% of U.S. districts provide one-to-one computers, and that PISA data links greater school screen time to lower test scores.
