One of ed-tech’s most powerful zombies, the learning management system, not only refused to die this year, but one of its makers, Instructure, had its initial public offering.(The latest on INST on the NYSE.) In related zombie news, Reuters reported in July that the most infamous LMS provider, Blackboard, was up for sale (again). But it doesn’t appear that there’ve been any buyers as of yet. The company continues to lay off employees, but alas it’s probably not a fatal blow for that particular monster.
