SUBMISSIONS
CONSISTENCY
SECURITY
It’s sometimes unclear
whether assignments
have been successfully
posted to student
drop-boxes.
Instructors are not
consistent about
assignment deadlines,
with some permitting late
assignments and some
forbidding them.
Having assignment
grades posted on the
system as soon as
they’re ready is
convenient, as long as
it’s secure.
The size limit for
submitted assignments
sometimes makes it
difficult to submit
program files using
databases or images.
Some instructors post
assignments on the
system, but most still
provide hard copies in
class.
Separate logins are
not required when
students shift from
one course’s drop-box
to another’s.
USABILITY
Many icons are
provided, but they’re
small, often obscure,
and have long delays
before tool-tips
appear.
