[LON-CAPA-users] Reduced Points for multiple attempts

I have written improved help instructions for the spreadsheet grading to
implement conditional grading, and also to make spreadsheet templates for
grade categories and easily apply the templates to individual loncapa
problems. For example, once a template has been created for on assessment
for partial credit, the template can readily applied to other problems. I
also use templates for grade categories to copy awarded points to particular
columns so that they are quickly tabulated for each category.

The edits have not yet been incorporated into the help files (perhaps
because I have not committed the changes to the repository - I can't
remember the status of the draft!), but if you are interested, send me an
e-mail off-list, and I can share the draft.

My method does change the 'Points Awarded' in the spreadsheet view, but I
have not tested in the Assessment Chart mentioned by Doug Mills.

P.S. I support the ability to save/load spreadsheet files which makes the
above process easier to share between courses.

I would recommend using the LON-CAPA spreadsheet to implement this grading
scheme for display of grades within LON-CAPA.

As regards export to Blackboard Learn, it would be straightforward to modify
the existing grade export script used in your domain (for which I
implemented some speed-ups at the end of last year) to support points
calculations that incorporate number of tries used, given that the number of
tries used by each student on each problem part are already available in the
md5_<courseid>_performance table for each course.

Contact me off-list if you'd like to pursue that option.

One of the outcomes of my previous work on grade export for purdue is that
the next LON-CAPA release includes a new domain configuration (and
associated changes in LON-CAPA internals):

"Default lifetime (since last update) can be set for 'temporary' MySQL
tables containing student performance data (course's homeserver only) by
course type, (can be overridden in a specific course via DC's 'View or
modify a course')."
