When a Stanford University professor offered a free online course in artificial intelligence in 2011, he had no idea that the experiment would attract 160,000 students from 190 countries and generate a wave of publicity.

That’s one of many examples of how technology is reshaping education around the world. From the rapid proliferation of massive open online courses (MOOCs), to the widespread use of mobile devices that support a variety of “blended learning” models (part online, part bricks-and-mortar based), technology is creating new challenges and opportunities for educational institutions of all types, from early education to universities.
