If your students are saving their files to e.g. /sharedStuff
and /sharedStuff is grouped to Students
and the permissions on /sharedStuff include the sgid bit (see 
http://en.wikipedia.org/wiki/Setgid)
then /the files that get created there will belong to Student group/, 
and folks in Student group will be able to do .... whatever the 
permission bits for the file permit.

mkdir /sharedStuff
chgrp Students /sharedStuff
chmod 2770 /sharedStuff

That allows the owner (presumably root) and folks in Students group to 
create & view files in /sharedStuff.
The permissions on the files actually control access, but I think umask 
defaults to 002, so I think the default will be that anyone in the 
Students group will probably be able to read/write those files.

best,
