I have teachers who are using the Google Assignment feature of Schoology and they really seem to like it. However, students who have submitted assignments are still able to add suggestions to the document. Although they are suggestions and I can see that, a lot of my teachers are concerned that the students are editing the document. It does seemed to look like it too if you are not super comfortable with the settings. I have explained the process and the way to tell the difference, but both they and I think it is discouraging to be required to edit each document prior to grading. The digital submissions etc is supposed to streamline the process rather than add steps. Is there a way to restrict the students to only view the document and the teacher comments? Right now after submission the students have the ability to add suggestions.
