Waiting to be graded area? Or not marked Completed until graded?
Once my students submit their assignments, they think they are good as it moves the work to the Completed section. HOWEVER, I have students who have turned in work by accident without realizing it, or who turn it in so any parents who check just see that they have no more Assignments due. From what I can tell, when I return Assignments that were not complete or need something fixed, it stays in their Completed section, which they don't always look at unless their the type of student who really likes to check teacher feedback. Could work not be moved to the Completed section until it is graded, have a section for Waiting to be graded, or bump any returned work back to under Assignments (and they can move it to completed if they just hit the return button again if they don't have to fix anything)???
