Grading Multiple Answer Questions

As an instructor in a large university physics course, I would like to have an additional grading option for each Multiple Answer question in which either (1) penalty credit deducted for each incorrect answer chosen = total question credit ÷ number of INCORRECT answers (rather than # of correct answers) or (2) the quiz creator can specify individually the amount (%) of credit to be deducted for each incorrect answer (or added for each correct answer).  The reason for this is that when the number of incorrect answer choices exceeds the number of correct answers, it is far too easy to get zero credit for choosing some incorrect answers along with correct answers.  The suggested grading schemes above allow that outcome to be avoided.  For reference, Blackboard's grading scheme for Multiple Answer questions included such options, so they are certainly feasible.  This option would help reduce student confusion and dissatisfaction with the grading of such questions.  My colleagues also support this suggestion.  Thank-you!
