I am the local evangelist for the #MTBoS. At least once a day, the phrase “this teacher I know on Twitter” or “this blog I read” or “the online community of which I am a part” comes out of my mouth. For example, the fabulous post on two column proofs by Math With Bad Drawings not only sparked a debate among my office mates, but I also passed it along to my Assistant Principal, and it is becoming the cornerstone of our Geometry curriculum revision effort.
I mentor a new teacher in my department whose courseload is all Algebra 1 (which I do not teach), so I have someone to which I can refer all of the great Algebra 1 ideas I read on line, like this great post on combining like terms at Simplify With Me. When I sent her @jreulbach’s post on 4 4’s, she used it the next day with great success, which sent her fragile first year teacher ego soaring.
I’ve passed along MathMunch (jeez – I’ve got the poster on my office door!), read Dan Meyer’s The Unengageables post out loud to groups of teachers (no wonder I’m so popular), and run a local professional development session on Desmos. Looking back through my email, I see that I am frequently sharing the incredible resources that is on my screen, in my phone, at my fingertips, every day. I’m still the only person I know actively tweeting (my children don’t, my students [most of them] don’t, my colleagues don’t), but I’m getting the word out. My teaching and my life have been greatly enriched by this MathTwitterBlogoSphere – and I will continue to share the wealth in my local community.
