Fig.1. What is a tutorial?
In my decade+ using these platforms (I first attempted a module of the Open & Distance Learning MA in 2000/2001)we've gone from 'computer-based learning' and 'web-based learning' to 'online learning' and 'e-learning' or 'eLearning'. 'MOOC' (Massive Open Online Course' is a dreadful term so 'Free Online Course' must surely be better?
It'll pan out over the years.
I have come to like 'hang-outs' (a term coined by Google) as an informal online gathering. A lecture online, is by default something akin to a 'TED lecture' surely? Webinars are a reasonable catch-all and perhaps what becomes of an OU Live moderated sessions?
Regarding tutorials, though traditionally small groups, a tutor and one or two, maybe three students for an hour - it is these asynchronous conversations that match this where the role of 'tutor' is taken by the educators, but also by well-informed contributors - this can happen here. The learning effect is, I would say the same, or very similar. You offer thoughts, these are challenged, or people agree and add or amend them and in this way you 'construct' meaning. Constructivism is one of the older 'learning theories', whereas 'connectivism' is very much a product of learning like this.
These is called a blog platform, yet it has affordance of what used to be called a 'Bulletin Board' (I did one of these with the OU in 2001. Think text messages strung together in a kind of Excel spreadsheet). A blog, for my money, has a modicum of independence of design, tools and sharing. Go see WordPress. I wouldn't change much here though. I cherish the new things I learn from people on totally different courses, the company and support that I know is here too.
