4526: =head1 Bubble sheet grading routines
4527:
4528: For this documentation:
4529:
4530: 'scanline' refers to the full line of characters
4531: from the file that we are parsing that represents one entire sheet
4532:
4533: 'bubble line' refers to the data
4534: representing the line of bubbles that are on the physical bubble sheet
4535:
4536:
4537: The overall process is that a scanned in bubble sheet data is uploaded
4538: into a course. When a user wants to grade, they select a
4539: sequence/folder of resources, a file of bubble sheet info, and pick
4540: one of the predefined configurations for what each scanline looks
4541: like.
4542:
4543: Next each scanline is checked for any errors of either 'missing
4544: bubbles' (it's an error because it may have been mis-scanned
4545: because too light bubbling), 'double bubble' (each bubble line should
4546: have no more that one letter picked), invalid or duplicated CODE,
4547: invalid student ID
4548:
4549: If the CODE option is used that determines the randomization of the
4550: homework problems, either way the student ID is looked up into a
4551: username:domain.
4552:
4553: During the validation phase the instructor can choose to skip scanlines.
4554:
4555: After the validation phase, there are now 3 bubble sheet files
4556:
4557: scantron_original_filename (unmodified original file)
4558: scantron_corrected_filename (file where the corrected information has replaced the original information)
4559: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4560:
4561: Also there is a separate hash nohist_scantrondata that contains extra
4562: correction information that isn't representable in the bubble sheet
4563: file (see &scantron_getfile() for more information)
4564:
4565: After all scanlines are either valid, marked as valid or skipped, then
4566: foreach line foreach problem in the picked sequence, an ssi request is
4567: made that simulates a user submitting their selected letter(s) against
4568: the homework problem.
