Do as much as you can electronically.
I love the instructors who ask for homework electronically. I even more love instructors who assign books that are available as e-books so I don't have to pay for shipping. I am so enamoured with people who don't require me to print things.
This is not an anti-book or anti-paper post, btw, but just a reminder that services like Google Docs and email attachments and Kindle for PC might save you a bit of cash on paper and ink while also keeping trees in the ground. And I'm all in favour of that, because I live in Austin and think any part of the city without shade is doing it wrong.
Are you a teacher who assigns (at least some) homework electronically? Do you avoid printing things? Should I go around Austin in the dead of night planting trees?
