BIG DEAL: According to market research firm CB Insights, venture capital investments in edtech companies during the first 6 months of 2013 ($481M) was down 26% from 2012 ($650M). But it sees no signs of an edtech bubble, but rather "an early part of Ed Tech's maturation...with the majority deals still in early/seed stages." Still, there were some notable big deals. In CB Insight's recent roundup of the 10 largest edtech rounds in 2013, Laureate Education ($150M), Lynda.com ($103M), and Open English ($65M) take the top three spots. Coursera is a close fourth with $63M B round (after a belated $20M addition in November). There's still three weeks left in the year and Christmas is coming---will someone else make the list?
