4654: =head1 Bubble sheet grading routines
4655:
4656: For this documentation:
4657:
4658: 'scanline' refers to the full line of characters
4659: from the file that we are parsing that represents one entire sheet
4660:
4661: 'bubble line' refers to the data
4662: representing the line of bubbles that are on the physical bubble sheet
4663:
4664:
4665: The overall process is that a scanned in bubble sheet data is uploaded
4666: into a course. When a user wants to grade, they select a
4667: sequence/folder of resources, a file of bubble sheet info, and pick
4668: one of the predefined configurations for what each scanline looks
4669: like.
4670:
4671: Next each scanline is checked for any errors of either 'missing
4672: bubbles' (it's an error because it may have been mis-scanned
4673: because too light bubbling), 'double bubble' (each bubble line should
4674: have no more that one letter picked), invalid or duplicated CODE,
4675: invalid student ID
4676:
4677: If the CODE option is used that determines the randomization of the
4678: homework problems, either way the student ID is looked up into a
4679: username:domain.
4680:
4681: During the validation phase the instructor can choose to skip scanlines.
4682:
4683: After the validation phase, there are now 3 bubble sheet files
4684:
4685: scantron_original_filename (unmodified original file)
4686: scantron_corrected_filename (file where the corrected information has replaced the original information)
4687: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4688:
4689: Also there is a separate hash nohist_scantrondata that contains extra
4690: correction information that isn't representable in the bubble sheet
4691: file (see &scantron_getfile() for more information)
4692:
4693: After all scanlines are either valid, marked as valid or skipped, then
4694: foreach line foreach problem in the picked sequence, an ssi request is
4695: made that simulates a user submitting their selected letter(s) against
4696: the homework problem.
