MVI: Zeal co-founder and former Rocketship Education CEO John Danner is a firm believer in the lean startup. On his blog, he offers his two cents on how the MVP (minimum viable product) approach highlights "similarities between engineering and instruction." Online learning will work best, he says, when it delivers "Minimum Viable Instruction" that "tests what [students] each need and gives them just enough to keep going." (Hopefully, this blurb was minimally viably interesting.)
