The Select Multiple Answer Regrade Tool or "S.M.A.R.T. Button" is a custom feature added to Canvas by the SON Instructional Design team based on code developed by James Jones and Avi Naiman and discovered by James Henson following some discussion in the Canvas Community.

The S.M.A.R.T. button contains the number of questions on the student's assessment that would be affected by clicking the button. The button will not show if it would not make any changes to the assessment. The S.M.A.R.T. button is disabled (grayed-out) after being run, but left visible on the screen so that you can see how many questions were affected. Using the button will change every select multiple answer question that has received partial credit. If you only want to grade, for example, question 5 using all or nothing and the rest as partial credit, you'll still need to do that manually.

Please make any additional Canvas regrades prior to using the S.M.A.R.T. button. If you regrade a question using Canvas, it may override changes that you made using the S.M.A.R.T. button and you may need to repeat the process of using the S.M.A.R.T. button.

How To:

Login to Canvas and go to the quiz page for the assessment that needs to have the Select Multiple Answer questions regraded as "All or Nothing".
Click on the SpeedGrader^TM link from the right-hand menu.
In the header of your assessment (if there are Select Multiple Answer questions that need to be regraded for the individual student) you will see the S.M.A.R.T. button with a number badge indicating how many questions need to be regraded for that student.
Click the S.M.A.R.T. button to re-grade the questions. You will notice that the S.M.A.R.T button becomes "grayed-out" and the Final Score will adjust to the new score.
Click on Update Scores to finalize and change the students score in the Gradebook. Once you have clicked Update Scores and the page has reloaded you will notice that both the Final Score and Grade _ out of ## now match.
Move to the next student and repeat the steps above.
