So I've been teaching calculus for over 10 years, almost (with the exception of one summer) exclusively out of some flavor of Stewart. And I've been a fan of the web and delivering content over the internet since beginning—I was cobbling together course web pages in the 90s before Blackboard and fancy content management systems were around.
Conference tweets broadcast beyond hotel ballroom
This is not a "Why I tweet" post nor is it a "What twitter is for" post. But it's a nice anecdote about how twitter works in interesting ways.
We've just wrapped up the 12th annual Legacy of R.L. Moore Conference in Austin, Texas. It's one of my favorite conferences and I decided to see if I could organize some collective twittering.
The sky is not falling (anymore? yet?)
A few months ago David Bressoud (incoming president of the MAA) wrote an article for Notices of the AMS called "Is the Sky Still Falling?" It refers to a 1995 Notices article (titled "The Sky is Falling") which worried about a rapid decline in the number of students enrolling in mathematics courses.
Bressoud's article contains good news and bad news. The good news is that enrollment in college math courses is up. One bit of bad news is that enrollment in all college courses is up, too, and the percentage of enrollments which are math courses continues to drop.
Tooting my own horn
I'm happy to announce that I've been awarded a grant from the Educational Advancement Foundation to develop a graduate student/postdoc teaching seminar.
