I stopped grading homework this year. It isn't worth anything. Not "points", not a percent. I also noticed that I was assigning less and less. I have a mixed feelings about this. Reading Dan Myer about this made me feel better. I wonder if he still feels the same as he did four years ago.
Not giving out points for papers filled with work of dubious value was definitely a good decision. I don't think I'll ever go back. Now how much to assign and how to maximize class time. That's still the battle.
