theodp writes: Code.org's AP Computer Science offering won't be going mainstream until the 2016-2017 school year. In the meantime, NewsWorks' Avi Wolfman-Arent reports that Rupert Murdoch's Amplify MOOC just wrapped up its second year of offering AP Computer Science A. And unlike Microsoft TEALS, Google CS First, and Code.org — programs constrained by the number of volunteers, teacher and classroom availability, professional development requirements, and money — Murdoch's AP CS MOOC holds the promise of open-access, unlimited-enrollment, learn-anywhere-and-anytime classes, a la Coursera, Udacity and EdX. So, did Microsoft, Google, Amazon, Facebook, and their leaders place a $30 million bet on the wrong horse when it comes to AP Computer Science scalability? And, even if they've got a more scalable model, will Murdoch's Amplify and schools be willing to deal with higher MOOC failure rates, and allow large numbers of students to try — and possibly drop or fail — AP CS without economic or academic consequences?
