Having the ability to grade HW assignments with annotation tools is a great idea; however, from my experience thus far, the system needs retooling.  1) It is not clear that you need to save each mark that you make otherwise if you enter the grade and go back to the assignment, your feedback and comments will not be there. The small check box that comes up is actually the "saving" mechanism. How does one suppose to know that the check mark means saving? 2) When I am using my stylus pen because I have a 2-1 laptop, the screen page moves as I am correcting HW. This causes marks to occur in places they should not occur because the page is shifting with each correction. I am not sure why when correcting a small box area is highlighted, and this is what is causing the shifting. Also, the check mark box that appears is located right in the place where you are grading, often times not allowing you to finish your comment.  This in itself almost makes the annotation tools worthless because there is so much extra work that I have to do, it slows you down, and it becomes frustrating.  3) You can only use the annotation tools when students upload a document. Unfortunately, some assignments are not necessary for student to create and save a document, but the system does not allow you to correct assignments of students that are submitted in the text box.  ...
