I did this about this time last year. Though then it was buried at the end of a much longer post about other things.
This is simply a bonus for any of my spring 2013 undergrads who happen to be reading this: Cut-and-paste any full entry from this blog and send it to me in an email. For every full course week left in the semester after your email lands in my inbox, I’ll add 0.5 points to your course grade. You’re free to share this information with your classmates if you so choose . . . but not on the course website. If news of this bonus ever lands there, the bonus goes away, and all previously awarded benefits will be taken away. And, perhaps needless to say, this is a one-time-only bonus for anyone who happens to collect it.
(For the curious out there, last year, out of 20 students who could have claimed this bonus, only 4 did.)
