Instructors may give feedback in various ways. The available options are in the Feedback types section of the assignment's settings page.

Comment inline: With online text submissions, this allows the instructor to give feedback directly on the students' work, in a similar way to grading on paper.

Feedback comments: This allows graders to leave comments about the students' submissions, as well as grades.

Offline grading worksheet: This gives the instructor a link to download the grading list as a spreadsheet. They will then be able to enter grades and feedback comments offline, and then re-upload the sheet. 

Feedback files: This allows graders to upload files with feedback when marking. These files may be the marked-up student assignments, documents with comments, a completed marking guide, or spoken audio feedback.
