Clickers would be to this process as a music score would be to a jam session.
The whole idea is chaotic interaction on the kid's side with an expert on the teacher's side. When I do it with math it's totally unscripted. I only start with a particular goal in mind and then I let it rip. I'm constantly analyzing for misconceptions, language hickups, arithmetic problems, process problems, etc. It's mentally grueling and physically exhausting.
There's no room for even a second's worth of technology. Technology would be an intrusion on a beautiful thing.
I've had some of my biggest problem students jumping up and down in this process yelling and thumping their chest saying "Yo! I'm smart!". These same kids, under discovery, eat their pencils and throw stuff.
No clickage. Not ever.
This seems like the moment to head on over to Amazon & pick up a copy of Weapons of Mass
Destruction Instruction: A Schoolteacher's Journey Through the Dark World of Compulsory Schooling. (thanks, V.)
