Math 15 Partial Credit Policy:
Since we are interested in the fundamental concepts of the calculus,
producing a correct numeric result is not the primary measure of success.
Instead, the process that leads to the answer will play an important role
in all the materials you turn in on quizzes and exams. A correct answer
with an incorrect method or explanation will receive little credit, while a
correct method with minor errors leading to an incorrect answer will
receive more credit. Your ability to explain what you are doing will be
taken into account in awarding partial credit; if I have to guess about
whether you understood what you did, you will receive less credit.
Many students feel that it is better to say something, even if you
know it is wrong, in hopes of getting some partial credit; however, this
really makes you look like you don't know what you are doing, and you
should avoid doing it. It is far better to admit that you don't know how
to do a problem and get extra help from me, either from explanations that I
write on your homework, or from coming to see me during office hours. My
grading will try to reinforce this approach:
- You will start with a certain number of points to begin with;
- Leaving the problem blank will get you that number of points;
- When you say correct things, you will get more points;
- When you say incorrect things, you will lose points.
So if you don't understand the problem, it may be better for you to say
nothing at all than to try to bluff your way through it. Also, if you say
some good things and some bad things, you may end up right back where you
started. It is to your benefit to think carefully about what you say.
I will try to write lots of comments on your work before I turn it
back. You should remember that this is to try to help you understand where
you have made errors, so if there is a lot of red ink on your paper, try
not to take this to mean that you are a terrible math student or a bad
person. It is my job to make these kinds of comments, and it is the only
way to learn where you need to work harder. Because of this, I spend most
of my time writing about what you did wrong, so you may not see as
many "good jobs" as you would like to see, and it may seem that I'm picking
on you. Remember that I am trying to help you understand where your work
is the weakest.
My marks have the following meanings:
- When you say something that I was looking for, I'll put a checkmark
next to it to indicate this. Lots of checkmarks is a good thing. Some
students have told me that in their high schools a check meant a mistake; here
it means that something is correct, so don't be confused.
- If you say something particularly well, or say something perceptive or
beyond the material that I expected you to get, I'll say "good job" or
"nice observation" or some such thing. I do not say this simply because
you got a problem right, but because you did something beyond what I
expected.
- If I say "OK" rather than giving a checkmark, this means that I'm
accepting what you say only grudgingly. Usually it means that what you
said is true but that you have not fully explained it, or that there are
subtleties that you have not seemed to grasp. It may also mean that there
is a better way of saying this, or a better reason to use. It may also
mean that what you say isn't quite true, but is wrong for technical or
subtle reasons, though I'll let it pass. You may want to ask me more about
why what you did isn't quite right.
As always, if you don't understand something that I've written on your
paper, or if you can't read my writing, please come see me about it and
I'll try to explain it.
