I, like you probably, have to pick out some goals for any given school year. Lately, part of our goals have had to be under some technology sub-domains. One of them happens to mention online collaboration and you do some self rating, etc, etc. I'm not sure if the experience I had (and have frequently) on Twitter last week can be neatly summarized into "never/sometimes/always."
A week ago I was sitting around getting some things together during my planning period and had an impromptu discussion on the necessity of trig identities:
- This happened in the middle of the school day in about 20 minutes
- Bowman got a series of opinions about his question
- More people than Bowman got something out of this
Most Pre-Cal teachers probably struggle with this question. And most likely, people teaching higher level math topics don't have a lot of local resources on the issue. Having that second opinion to validate a teaching move or direction is so key.
My local math department is great. My global math department is fannnnnntastic.
