4540: =head1 Bubble sheet grading routines
4541:
1.424 albertel 4542: For this documentation:
4543:
4544: 'scanline' refers to the full line of characters
4545: from the file that we are parsing that represents one entire sheet
4546:
4547: 'bubble line' refers to the data
4548: representing the line of bubbles that are on the physical bubble sheet
4549:
4550:
4551: The overall process is that a scanned in bubble sheet data is uploaded
4552: into a course. When a user wants to grade, they select a
4553: sequence/folder of resources, a file of bubble sheet info, and pick
4554: one of the predefined configurations for what each scanline looks
4555: like.
4556:
4557: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4558: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4559: because too light bubbling), 'double bubble' (each bubble line should
4560: have no more that one letter picked), invalid or duplicated CODE,
4561: invalid student ID
4562:
4563: If the CODE option is used that determines the randomization of the
4564: homework problems, either way the student ID is looked up into a
4565: username:domain.
4566:
4567: During the validation phase the instructor can choose to skip scanlines.
4568:
1.435 foxr 4569: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4570:
4571: scantron_original_filename (unmodified original file)
4572: scantron_corrected_filename (file where the corrected information has replaced the original information)
4573: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4574:
4575: Also there is a separate hash nohist_scantrondata that contains extra
4576: correction information that isn't representable in the bubble sheet
4577: file (see &scantron_getfile() for more information)
4578:
4579: After all scanlines are either valid, marked as valid or skipped, then
4580: foreach line foreach problem in the picked sequence, an ssi request is
4581: made that simulates a user submitting their selected letter(s) against
4582: the homework problem.
