In this article, the developers of seven Language Massive Open Online
Courses (LMOOCs), Icelandic Online (IOL, https://icelandiconline.com/),
describe the technological and pedagogical principles that have contributed
to the program’s longevity. Development began in 2001 with a courseware
system later upgraded to a multiplatform app. Over 80,000 users have
completed one or more of the curated and pedagogically driven courses, which
are monitored by a tracking system. The tracking system and follow-up
surveys generate unique, large-scale empirical data enabling sustained
engagement with participants’ views and behaviors as they go through the
courses, some of which are offered in three different delivery modes.
Finally, further development projects based on the versatile IOL
non-language specific, multiplatform system are presented, including Virtual
Reality (VR) projects, courses in other languages, and L2 literacy courses
for children.
