Today I discovered that my department chair had ordered a set of Auspen refillable whiteboard markers for me and a number of extra markers for my students. If you’ve never seen them before, Auspens are refillable dry erase markers—when the ink runs out, you simply unscrew the top, and put in a few drops of ink, reseal the marker and you’re back to writing. They’re wonderful, not too expensive ($1.50/marker), and so much better for the planet than disposable markers. They also don’t smell bad either.
One bit of caution. If you do get these markers you’ll need to get in the habit of recapping them when you finish wiring, and developing some good marker care and feeding habits among your students. See Kelly O’Shea’s post on marker buckets for some pro tips for marker care.
