Method 1: Using folder (As AL Rachels said, enable separate
groups; Change Student permission: Manage files in folder=Allow)
Pros: Easy to use
Cons: If you have 10 groups, then you need to create 10 folders, change permission 10 times, setup access restrictions 10 times. If you want a link from your 'Front page' to the folders, again, 10 URL links, 10 restriction settings. Inside the folders, no record of history, no ownership of files, students can delete others' files.
Method 2: Using Wiki (enable separate groups).
Pros: Easy for teacher, just set ‘Group mode=Separate groups’. All files show who is the owner; Changes are recorded into the history Tab; and versions can be rolled back when needed.
Cons: Students have to learn how to use Wiki.
Method 3: Using Group Assignment (You don’t have to enable separate groups, just set ‘Group submission setting=Yes)
Pros: Easy for teacher, as long as groups are there, all done. Easy for students, just like a normal assignment submission. Good for all group members to work on ONE word file.
Cons: Among group members, students can see who is the owner of a file, but can edit/delete a file, no rollback function.
Method 4: Using a Database activity (Just import the preset attached, make sure you have enabled separate groups )
Pros: Easy to use, simple interface, all files shows ownership, time tag, student can make comments to each other, but won’t be able to delete others’ files.
Cons: Teachers have to learn how to build a Database if they want more features than the one attached. Please go to Database forum if they have any question.
