In a New York Times article, Pappano (2012) declared 2012 as ‘the year of the MOOC’. It was a year which saw a surge in interest in this new, open form of online higher education. While the initial hype around Massive Open Online Courses (MOOCs) subsided and their form has changed significantly from the first large-scale courses, more learners than ever are registered with the platforms, which have attracted substantial levels of investment. In this special collection, we bring together articles published in the Journal of Interactive Media in Education over the past ten years, which have focused upon MOOCs from a diverse range of research perspectives. First, we provide an overview of major events and trends in relation to MOOCs over the past ten years. We then take a closer look at the 25 papers published in JIME and included in the virtual special collection, arranged in relation to four main themes, including: situating MOOCs; learning design and roles; MOOCs and languages; and accessibility and inclusion.
