A Classroom Software Boom, but Mixed Results Despite the Hype - NYTimes.com:
"Carnegie, one of the most respected of the educational software firms, is hardly alone in overpromising or misleading. The Web site of Houghton Mifflin Harcourt says that “based on scientific research, Destination Reading is a powerful early literacy and adolescent literacy program,” but it fails to mention that it was one of the products the Department of Education found in 2009 not to have statistically significant effects on test scores.
Similarly, Pearson’s Web site cites several studies of its own to support its claim that Waterford Early Learning improves literacy, without acknowledging the same 2009 study’s conclusion that it had little impact."
