Like spiders in boots, on-line instructors wear 8 shoes.I don't think the roles for on-line teaching are any different than for F2F teaching. The context and delivery are different. The strategies and tools are different. But the roles are the same. Like a green teacher just off the boat and thrown into a class of 25 screaming kids, there will be a lot of learning as you go and mistakes made. I also know that after a few rounds, the comfort level increases dramatically and the quality increases exponentially.
I know I'll have a lot to learn if I ever wear that headset for a paycheck but I'm confident I'll be able to have a pretty good start and go up from there.
I thought I'd try a Popplet once.
