4585: =head1 Bubble sheet grading routines
4586:
4587: For this documentation:
4588:
4589: 'scanline' refers to the full line of characters
4590: from the file that we are parsing that represents one entire sheet
4591:
4592: 'bubble line' refers to the data
4593: representing the line of bubbles that are on the physical bubble sheet
4594:
4595:
4596: The overall process is that a scanned in bubble sheet data is uploaded
4597: into a course. When a user wants to grade, they select a
4598: sequence/folder of resources, a file of bubble sheet info, and pick
4599: one of the predefined configurations for what each scanline looks
4600: like.
4601:
4602: Next each scanline is checked for any errors of either 'missing
4603: bubbles' (it's an error because it may have been mis-scanned
4604: because too light bubbling), 'double bubble' (each bubble line should
4605: have no more that one letter picked), invalid or duplicated CODE,
4606: invalid student ID
4607:
4608: If the CODE option is used that determines the randomization of the
4609: homework problems, either way the student ID is looked up into a
4610: username:domain.
4611:
4612: During the validation phase the instructor can choose to skip scanlines.
4613:
4614: After the validation phase, there are now 3 bubble sheet files
4615:
4616: scantron_original_filename (unmodified original file)
4617: scantron_corrected_filename (file where the corrected information has replaced the original information)
4618: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4619:
4620: Also there is a separate hash nohist_scantrondata that contains extra
4621: correction information that isn't representable in the bubble sheet
4622: file (see &scantron_getfile() for more information)
4623:
4624: After all scanlines are either valid, marked as valid or skipped, then
4625: foreach line foreach problem in the picked sequence, an ssi request is
4626: made that simulates a user submitting their selected letter(s) against
4627: the homework problem.
