4586: =head1 Bubble sheet grading routines
4587:
4588: For this documentation:
4589:
4590: 'scanline' refers to the full line of characters
4591: from the file that we are parsing that represents one entire sheet
4592:
4593: 'bubble line' refers to the data
4594: representing the line of bubbles that are on the physical bubble sheet
4595:
4596:
4597: The overall process is that a scanned in bubble sheet data is uploaded
4598: into a course. When a user wants to grade, they select a
4599: sequence/folder of resources, a file of bubble sheet info, and pick
4600: one of the predefined configurations for what each scanline looks
4601: like.
4602:
4603: Next each scanline is checked for any errors of either 'missing
4604: bubbles' (it's an error because it may have been mis-scanned
4605: because too light bubbling), 'double bubble' (each bubble line should
4606: have no more that one letter picked), invalid or duplicated CODE,
4607: invalid student ID
4608:
4609: If the CODE option is used that determines the randomization of the
4610: homework problems, either way the student ID is looked up into a
4611: username:domain.
4612:
4613: During the validation phase the instructor can choose to skip scanlines.
4614:
4615: After the validation phase, there are now 3 bubble sheet files
4616:
4617: scantron_original_filename (unmodified original file)
4618: scantron_corrected_filename (file where the corrected information has replaced the original information)
4619: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4620:
4621: Also there is a separate hash nohist_scantrondata that contains extra
4622: correction information that isn't representable in the bubble sheet
4623: file (see &scantron_getfile() for more information)
4624:
4625: After all scanlines are either valid, marked as valid or skipped, then
4626: foreach line foreach problem in the picked sequence, an ssi request is
4627: made that simulates a user submitting their selected letter(s) against
4628: the homework problem.
