Has science or technology revealed any secrets recently that would change how you teach these topics? For example, when I studied electronics as a kid, the theory was that electrons travelled through conductors at almost the speed of light. I think it's now well know that individual electrons actually travel through conductors quite slowly.

I don't know when did you learn that, but no physicist worth their salt would say that by mid 1930s at the latest, I'd hope.
