Example:
Class Name: English 12
Section: Period 3
Cons of "Students can view file": students can chat with each other on the document and you can imagine how quickly that can get out of hand.
Cons of "Students can edit the file": it is what it says. All students will be able to edit the SAME file. Picture Lord of the Flies in the digital era.
It will record who says what but that doesn't always mean students will behave.
You can delete posts from students.
Students CAN unsubmit and resubmit an assignment but everything in Google Classroom is always TIMESTAMPED.
