Thanks for the comments Andrew. I find my engagement with online learning is really influenced by how well the course has been designed and how easy it is to navigate. I also find that I often share and discuss what I have found online with my colleagues that I coach with. I engage with something online but often think about it, reflect and process it through discussion with others when we meet. It highlights the complexity of understanding the learning process.
I think coach developers and coach educators can in a way act as mediators/curators but I would be wary of giving and directing advice to coaches. I would let coaches navigate the world of online opportunities themselves, discover things and then use me as a sounding board to chat and discuss the ideas and content they have found further. I'm undertaking this process at the moment. A fellow coach at our club is undertaking a MSc in Sports Coaching online. We have a weekly chat at training about what he is doing and what do I think about it. I'm kind of acting as a sense-check for him rather than a mediator or curator of material.
Something else I thinking about is Rhizomatic Learning and how applicable it is to coach education. You can google it and find out more, I'm sure you will find it interesting.
