Hi Mike - I've done four MOOC courses in the past. For me the 3 hours is optimistic, more like 6, but it depends on the course, how much knowledge you already have and how much time you spend on the blogs with others. The interaction is part of the learning process although it doesn't usually contribute to the end grade. The lectures are not time dependent, sometimes there is a way of downloading a pdf transcript or a video file. With the Future learn courses there tends to be one peer reviewed assignment and a number of tests on the way through the course. From what I have read I think we will be asked to post photographs. Since the courses are free you can always sign up and complete as much as you can, if it's run again you can repeat it, if you don't need tthe certificate there is usually someone lurking on the course site well after the official end of the course to peer review. Good luck in your new job
I have recently retired, lots of time no money Fortunately I bought a scope when I was working, which I have now dusted off. Maybe all that rain last year deterred me from getting full use out of it. I have signed up for a MOOC (Free! from Future Learn) on Orion run by the Open University - anyone else tried this? I have a lot to learn, let's hope the weather is kind in January when the course starts.
