I (teacher) wrote a comment and posted a paper on the gradebook for the wrong student, how do I remove it?
Hi Mary B. Doyle - You can delete a comment within Speedgrader by click the "X" over to the right of your comment, as illustrated on a few screen captures here: How do I leave feedback comments for student submissions in SpeedGrader? This is true even if you left the comment by clicking the little "comment" icon in the Gradebook. While there is seemingly no way to remove a comment left in the Gradebook that way, the same comment will seen in Speedgrader for that assignment.
However, I hope that you muted this assignment. Because even though you remove a comment, depending on the student's notification settings for Submission Comments, s/he may have very well have been emailed the comment if the assignment was not muted.
Hope this helps a bit.
