I will allow a student under my university's policy to resubmit an assignment to earn additional points unless I determine that the assignment contained evidence of academic dishonesty. I refer the paper to the university's committee to review my concerns for academic dishonesty.
I will encounter instances of a "teaching moment", if the academic issue is minor and not deliberate, I will accept the assignment and award the appropriate number of points. I will not refer this assignment to the university for academic discipline.
I will allow a student to submit the correct assignment if the original submission was submitted in error. That is, I receive a marketing paper for my economic course.
If a student has totally missed the mark, I allow a revision only if they discuss the revision and agree on the maximum points that could be returned to the grade book.
I consider every communication with a student as a teaching opportunity and avoid, whenever possible, making an evaluation a time for "punishment"
