If you're familiar with using Canvas's Speed Grader as a U of M faculty member, you'll find that GradeCraft doesn't offer a similar tool currently. However, GradeCraft provides alternative methods for providing feedback efficiently. Instructors can use the Quick Grade feature for quick and concise feedback or the Rubric Tool for more comprehensive assessment. Additionally, instructors can download student submissions, offer comments directly on the files, and then reattach them to submissions for in line commentary.
