Through twitter, you can learn about instructional strategies, tech tools, and the various current "initiatives" in public education. You can take part in professional chats with other educators around the world. (And the state, try searching for "INeLearn" on a Thursday night.). Basically, you get to choose your own professional development and the possibilities are endless.
I've found that if an educator does not like twitter, they probably don't know how to use it to discover their personal and professional interests. If anyone would like to learn how to get started and use it professionally, let me know.
You can use twitter with your students, too. Last week, my fourth period class joined other high school students in talking to physicists, astrophysicists, and college professors about the asteroid and meteor events. @timwilhelmus recently tweeted this website http://bit.ly/X8f12w. Lots of ideas on how to use twitter there. If you already are on twitter, could you comment below with your username? We can make sure that we're all connected :)
Anyway, I've had a very hard couple of weeks. @kevinhoneycutt (who spoke at a past elearning revolution event) retweeted this video. It made me laugh because I definitely related to it this past week. The script is the result of a girl trying to teach a younger girl how to subtract. Not a great example of how amazing twitter can be as choose-your-own PD, but hey, it made me laugh.
