I've never counted how many short online courses I have done since I graduated with the MA in Open and Distance Education in 2013. I did a further two modules of the MAODE straight up - as if to finish the set and because I couldn't let go of learning; I still can't.
Since then, if asked how many courses I had done I might have said 11 or so. Maybe I would have muttered that I'd done around 11 on FutureLearn, 6 on Coursera and a couple of other one offs, such as a course with Oxford Brookes on Teaching in Higher Education.
I have just done a tally.
Since FutureLearn launched in 2012 I have signed up for no fewer than 45 of their courses, including the first on Web Sciences from the University of Southampton. Of these I completed 17 and went the full hog and got certificates for 6.
Coursera knows how to keep the time-wasters at bay. You pay upfront! This explains why I have signed up for 8 courses and completed 7. These have been on Learning How to Learn, Photography and Search Engine Optimisation. I also did the Coursera Community Mentor course and become a mentor on the first two modules mentioned here.
I also took the 8 week Take Your Teaching Online course from OpenLearn. Do it! This one's free
Meanwhile, out in the real world, I do life drawing. Not so much in lock down. But there's some contrast. Life-drawing and learning to sail!
