I like the idea of guiding students, giving them a little more information each time they ask for help. I also think they should get the right answer. I am big about partial credit. If they got a number wrong, they got a number wrong. But I also believe in giving them a lot of credit if they have the right steps. With Expert TA’s true partial credit grading system, instructors can do both.

With my students, I found that Expert TA was a way for them to help themselves, rather than seeing it as something that is just being assigned so they can get a grade. Initially, I set it up so they lose very little for clicking hints. I also gave them up to 10 different times to submit an answer. They are able to work through a problem on their own rather than being worried that asking for hints would get them a zero.
