Hi,
This is a long email.
I've created a problem similar to one that has
been discussed on the list-serve before that is a
weak attempt at getting around the inability for
students reset their own submissions.
So, I've got the situation where when I test
the problem in my construction space and I enter data
that is out of range and I get the message from
Lon-Capa that says 'Incorrect'. Just what I
would expect from Lon-Capa for a question that
was answered incorrectly. However, once I've
published the problem and use it from a
course I don't get the 'Incorrect' for answers
out of range, I get the message 'Answer Submitted:
Your final submission will be graded after the due
date.' You can actually re-enter the correct data
and press the submit button and move on but many of
the students just quite right there even though we
tell them what to do.
Can someone else confirm this and is this bug
worthy?
Below is a copy of the problem set. It could be
cut and pasted. Brief description of the code:
-conditional statements and control the display of the
questions since some of the questions need lab data to be
entered before answers can be calculated for them.
-this is an attempt to allow students to re-enter that
lab data.
Thanks for any help.
