I set up a Twitter account last year and didn't stick with it. I don't think anyone really cares to know that I'm headed to the grocery store or am just back from buying shoes. Have you seen that commercial? I laugh every time! I don't have a smart phone. I've had the same phone since I first started dating my husband five years ago. If I did have a smart phone, then I'd maybe keep up with stuff like this. I was reading through some of the suggested readings for this thing, and I did come away with these two ideas: 1) You can learn to say what you need to say in short, succinct statements. 2) Need help with something? Someone out there is bound to have some sort of advice or opinion. For educational use, you can follow people in the edu world, but you can also create an account for your students to reply to. Keep them on their toes- ask meaningful questions and see what they have to say in response.
I LOVED reading about back-channeling, and I loved how it was described as passing notes during the presentation! I think this would be really useful in professional development courses. Sometimes you have a question you're dying to ask, but then you either forget or there ends up being zero time. I think back-channeling would be awesome in a classroom setting especially for those students who are too shy. As a teacher, you can gauge how the lesson is going- what do I need to re-teach? What do I need to go more in-depth on? Students can also start up conversations that you would never have even thought of.
