It would be great if there was a box that the student needed to check before they were allowed to see the assignment grade. This would show that they have read and understand the instructor comments before viewing the grade. Too many students are just looking at the grade and ignoring the comments. I will input the same comments week after week and the students are not changing their behavior or taking any of the suggestions made by the instructor.
It would be a box they would check and next to it would state, "I acknowledge and understand the comments made by the instructor for this assignment." Once the box is checked the student could then view their grade. This provides accountability to the student and as well as instructor to ensure they are providing quality feedback to the students.
