Teachers can leave feedback on student annotations on any assignment. To access student annotations, go to the Assignments page for the class and click "Dashboard" for the particular assignment.
From the Dashboard page, click "Student Annotations" in the menu on the left. You can switch between students using the drop-down in the top-right of the Student Annotations page. You can click the "SEE LATEST ANNOTATIONS" button to view any new annotations added by that student since the last page load.
After choosing a student's name from the drop-down, click on an annotation to provide feedback. This will reveal the exact segment the student annotated underlined in green, as well as a "Reply..." box. Add your comment in the box and then click the REPLY button to publish the comment. As soon as you add your comment, the student will see it on their assignment if they refresh the page.
To edit or delete your comment, click the three stacked dots in the upper right-hand corner of the comment box and then select Edit Reply or Delete Reply.
Teachers can comment on a student annotations at any point, including before or after a student has submitted an assignment. However, please note that students can only annotate an assignment before they have submitted it.
