What is online learning in museums?

I've been reflecting quite a lot recently on what online learning means in a museum context. 

Is it just for schools?

Or just for schools and children outside schools?

Or for schools, children and adults taking part in a formal course?

Or is it for everyone? 

What constitutes learning in an online context?

Is it learning that takes place when you're looking at something online?

Or is it the delivery online of tools that help you learn on- and offline?

And where do you see responsibility for online learning as sitting within a museum?

I obviously have views of my own on all these things, and I may blog about them at some point, but I'm interested to hear what other people think and what museum online learning is seen as being. 

Please leave your comments here if you have a view on this! I'd be really interested to hear people's thoughts. And please feel free to raise further questions too if you have any!

Thanks all!
