One of the things I love about Twitter is the opportunity it provides for feedback on creative work. And thinking about teaching and learning mathematics is some of the most creative work I know. I’m still amazed when folks I’ve never met in real life take time out of their day to help me improve. Here’s a case in that beautiful point. Points, …

Time for a #slowmathchat Shift

I’ve shared here on the blog, and also in several recent conference sessions, that Twitter has changed my life. No exaggeration. Not even in the slightest. I’ve heard similar sentiments from quite a few others, including this from John Stevens: @mjfenton from blog posts to new resources to shoulders to lean on, the #MTBoS has done more for my career …

NCTM Nashville 2015

I spent Wednesday through Friday of last week in Nashville, TN for the 2015 NCTM Regional Conference and Exposition. Instead of writing a full-blown recap (bedtime approaches) I’ll simply share a question that’s been on my mind since my return flight touched down in Fresno late Friday night. Okay, it’s not really a question, but a series of questions. Here goes: What …

True Confessions

True confession #1: Twitter changed my life. That may sound strange, considering the following: I generally hate social media. I joined that Facebook thing all you kids talk about all the time, then decided it was a waste and deleted my account. When I first heard about Twitter, I thought, “Who cares what Bieber had for breakfast?!” I didn’t start texting until 2009. When I …

Why Twitter?

Earlier this week, as part of a larger workshop on mathematics and technology, I gave an introduction to Twitter as a digital collaboration playground for educators. I wanted to give my “pitch” using more than my own words, so the night before I posted this: Hey #MTBoS, can you give me 140 characters on how Twitter impacts your teaching life? Gathering responses to …

I love Twitter. I think I’m on record in several places with this. (Actually, it’s probably more along the lines of “I love the Twitter,” just because it’s more fun to say it that way. Go ahead, give it a try.) I love Twitter chats. This is probably less well known. And the less-well-known-ness is likely a result of my general lack of participation in …
