No two teachers have the same students, so they should be able to serve their students in different ways.
I’m a fan of Randall Munroe, the guy behind the Web comic XKCD and the book What If?. I’m also a big supporter of the effort to end polio. So anything that combines Randall and polio eradication is great in my book.
Here's a strip Randall drew for us in honor of World Polio Day. I got a kick out of it and thought I'd share it with you.
