On-line courses - Future Learn or Coursera

What age are your students? I teach at a school with some pretty bright kids and we have sort of faffed about with these a bit. Two things of varying success:

1. If a pupil is genuinely interested in a given subject area (or thinks they are), having a bit of a go at following one of the courses can give them a good insight into some areas they might otherwise not cover. It can also be a good point to gain 'supra-curricular' (yuk term) points - at least attempting a course shows genuine engagement with a subject and in the competitive business of university places can be useful in interview.
   
2. A sort of online reading group type affair. A guy in Physics tried it with (I think) something he thought some pupils in the Sixth Form would be interested in. They signed up, did a bit of logging on and then met periodically to discuss what had been covered. The teacher was then able to explain stuff or go over it etc.
   
   

I guess it depends what kind of students you are working with. Am happy to say more if you are interested.
