I think this is the first time WJ has repeated a webinar topic in such a short period of time. That just proves to me what an important topic it is. Informal learning is instinctive for us humans. It's crucial to create environments that encourage and facilitate it and that certainly do not inhibit it.
I realized during the webinar that I was experiencing some valuable informal learning through the chat interactions---right in the midst of the more formal delivery by Lori. I learned about
Overdrive, which was completely new information to me. Some people find running chat distracting, but I think it's a fine example of providing an environment that maximizes learning and peer-to-peer knowledge sharing.
