Following the FTI last May, I focused my Twitter account on feeds relevant to my professional life. I am still trying to figure out exactly what “professional” in this context means — right now, basically it means, “Stuff I like reading on Twitter while I’m at work.” Here are some “people” I follow:

But the most useful part of Twitter has been connecting with other math professors and math educators. I’ve found out about really fantastic resources from them, and I have no idea how I’d ever learn about things without them.

Great things I learned about via Twitter:

  1. The open-source graphing plotter “Graph”: http://www.padowan.dk/
  2. This open-source, free, activity-based calculus book: http://opencalculus.wordpress.com/
  3. How to do Origami in Geogebra: http://www.geogebratube.org/material/show/id/883
  4. Why we need more women math majors: http://kinlin.com/blog/2012/09/why-we-need-more-women-math-majors/
  5. The Wolfram|Alpha Chrome extension: http://wolframalpha.tumblr.com/post/33907023300/download-the-wolfram-alpha-chrome-extension
