How do you learn eLearning?
I'm going to look at this question from several perspectives. Firstly, as a teacher who attempts to utilise eLearning in my practice I have historically relied on "gut intuition" and anecdotal experience to decide to utilise those technologies I am most comfortable with myself in my teaching. In particular, Google Apps for Education (Drive, YouTube etc) seem to meet a lot of needs that just seemed to make sense to me as well as engage the students and result in (apparent) motivation. Of course what I have not considered enough is whether or not doing things in this way actually improved educational outcomes for the students. Carrying out a detailed inquiry into the impact of these activities seemed a very daunting task given all the other work that keeps piling up. So - in short - it seems like a lot of guesswork really, tempered by critical reflection to the extent that I thought "Did that seem to work?"
I think in the first place I've been lucky in that I've never struggled to get a grip on the technology in the first place. Particularly cloud-based apps such as Google Drive, which allows students real-time collaboration, and Google Sites, which allows students to easily build portfolios of their learning and teachers to easily coordinate blended learning approaches etc.
