To add Notes or Feedback to a students submission for internal moderation (that students cannot see) you go to Gradebook and click on the Marks tab.

Then if you have marked the students’ work it should have a mark displayed. Simply click on their mark and select Feedback & Notes.

 
 
 
Then use the Marker Notes text box to add notes or feedback and click Save.
