Hello Brian,
I do not teach (much to my regrets) but I have been thinking about what you
describe.
See below.

Hello,
I have a couple of classes where I teach introductory programming using
Python. What
I would love to have is for the students to go through a lot of very small
programs,
to learn the basic programming structure. Things like, return the maximum
in a list,
making lists with certain patterns, very simple string parsing,
etc. Unfortunately,
it takes a lot of time to grade such things by hand, so I would like to
automate it
as much as possible.
I envision a number of possible solutions. In one solution, I provide a
function
template with a docstring, and they have to fill it in to past a
doctest. Is there a
good (and safe) way to do that online? Something like having a student
post code,
and the doctest returns. I'd love to allow them to submit until they get
it, logging
each attempt.
I may have a partial solution. I (co-)wrote a program called Crunchy
(crunchy.sf.net)
which, among other features, allow automated correction of code that has to
satisfy a given docstring. As it stands, it only allows self-evaluation i.e.
there's no login required nor is the solution forwarded to someone else.
(This has been requested by others and may, eventually, be incorporated in
Crunchy.) So, as a tool for learning, it's working; the grading component
is simply not there. However, the code is open-source and you could adopt
it to your needs ;-)
André
Or perhaps there is a better way to do this sort of thing. How do others
who teach
Python handle this?
thanks,
Brian Blais
