I'm lucky enough to teach in a school that has small classes; I get to be very accessible to the students. There is some auto-grading, but most homework I grade by hand and give partial credit.

But if my classes were 300 people, I couldn't do that.

I also have relaxed deadlines so students can take more time if they need it, and request it in advance.

The object is to learn stuff. That's where I'm aiming.
