This blog could also be a very interesting discussion for another time. What I would like to briefly cover is not what people's different backgrounds are, but more what they could be, and how it doesn't really matter. Canvas has now been taught to academics from all over my institution in all the different disciplines and sub-disciplines that that entails. The original Canvas Facilitators at my institution were PhD students from all over the University. What we do for out academic careers really has nothing to do with it. By training I am an archaeologist, I have worked in Egypt and visit museums all over the place for my research. In my studies I have had a bit of exposure to different technologies and without talking myself up I am competent at a number of them. That was probably part of the reason why I was offered a job to teach Canvas to others, my day job involves teaching and my skills included technology.
I have had some emails recently of people saying that things are a bit too difficult or that they "don't understand this stuff". In particular I have had people saying that this guide on how to manage the lecture recordings is too difficult iframes (UoA Lecture Recordings) because it involves a little bit of copy and paste html. The second people see that they seem to switch off or dismiss it immediately. To be honest, I don't really know a great deal of html either, but I can figure it out if needed. That is the main skill that I see lacking in people who find these things too hard, they simply need to give it a go and try figure it out. These people are Academics from all disciplines. There are other people at the other end of the spectrum of course, who understand it and improve on it, which is great.
So, with Canvas, it doesn't really matter what you do if Canvas or e-learning is not your main job, it can be learnt either way. It doesn't matter if you don't do computer science or use computers for much beyond documents and email. I see Canvas as an augmentation of my teaching skills. Does it have anything to do with archaeology? No of course not, but that doesn't mean I'm not willing to sit down and figure it out. So if Canvas is not your day job, that doesn't matter, it can be figured out with patience, willingness, and time.
