Recently NPR did a story that had the general title The Online Education Revolution Drifts Off Course. And yet the article was focused solely on MOOCs (massive open online courses). Let's be clear that MOOCs are just one part of the so-called online learning revolution. (Don't forget blended learning, the flipped classroom, etc). The story was a strong critique on MOOCs and their effectiveness.
