I don't think you can set ownership in that way.  If the file-dropping
user belongs to the group owner of the directory, then you can set
default GROUP ownership by making the directory setgid (chmod g+s
DIRECTORY).

But ... I think that applies only to files which are created in the
directory, not files which are copied to it. (try it to see if that's
how it works for you)

My simpleminded fix would be to set a cron job to run periodically
(even every minute, I suppose).  Something like:

find DIRECTORY -type f -print0|xargs -0 --no-run-if-empty chown TEACHER

or

find DIRECTORY -type f -print0|xargs -0 --no-run-if-empty chmod 740
