I currently grade for a college calculus course, and I have graded for high school classes during my practicums. I just wanted to get some other opinions on something that is probably trivial to most. This probably applies to disciplines besides math (like science) as well. When you grade a 10 point problem that is half correct, do you give the student -5 or +5? (Similarly for any point value, this is just an example.) When I started grading, I would give them -5. Now I give them +5. It takes a little longer because I need to write a point value that they EARNED by each problem (whereas with the "-" system I did not write anything by a completely correct problem, I now write +10 or whatever it is worth), but I prefer it. Even though the grades come out the same, it makes me feel like grading is not punitive. I am not looking to catch them slipping up, I am looking to see where they have good insight and good ideas. Sometimes I may be a bit too generous with partial credit (heck, I usually give at least 1 out of 10 just for writing something instead of leaving it blank!), but I just think going through and trying to GIVE points instead of TAKE them makes grading more enjoyable. Any thoughts?
