There’s been quite a bit of discussion about the pedagogical effectiveness of massive open online courses, but in truth, most of the pedagogical strategies employed by MOOCs have been used for many years in other contexts.  In a paper published in the journal First Monday, Australian researchers David George Glance, Martin Forsey and Miles Riley do a thorough review of the published research addressing the most common MOOC pedagogical strategies.  Here’s the abstract:

In 2011, the respective roles of higher education institutions and students worldwide were brought into question by the rise of the massive open online course (MOOC). MOOCs are defined by signature characteristics that include: lectures formatted as short videos combined with formative quizzes; automated assessment and/or peer and self–assessment and an online forum for peer support and discussion. Although not specifically designed to optimise learning, claims have been made that MOOCs are based on sound pedagogical foundations that are at the very least comparable with courses offered by universities in face–to–face mode. To validate this, we examined the literature for empirical evidence substantiating such claims. Although empirical evidence directly related to MOOCs was difficult to find, the evidence suggests that there is no reason to believe that MOOCs are any less effective a learning experience than their face–to–face counterparts. Indeed, in some aspects, they may actually improve learning outcomes.
