4422: =head1 Bubble sheet grading routines
4423:
4424: For this documentation:
4425:
4426: 'scanline' refers to the full line of characters
4427: from the file that we are parsing that represents one entire sheet
4428:
4429: 'bubble line' refers to the data
4430: representing the line of bubbles that are on the physical bubble sheet
4431:
4432:
4433: The overall process is that a scanned in bubble sheet data is uploaded
4434: into a course. When a user wants to grade, they select a
4435: sequence/folder of resources, a file of bubble sheet info, and pick
4436: one of the predefined configurations for what each scanline looks
4437: like.
4438:
4439: Next each scanline is checked for any errors of either 'missing
4440: bubbles' (it's an error because it may have been mis-scanned
4441: because too light bubbling), 'double bubble' (each bubble line should
4442: have no more that one letter picked), invalid or duplicated CODE,
4443: invalid student ID
4444:
4445: If the CODE option is used that determines the randomization of the
4446: homework problems, either way the student ID is looked up into a
4447: username:domain.
4448:
4449: During the validation phase the instructor can choose to skip scanlines.
4450:
4451: After the validation phase, there are now 3 bubble sheet files
4452:
4453: scantron_original_filename (unmodified original file)
4454: scantron_corrected_filename (file where the corrected information has replaced the original information)
4455: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4456:
4457: Also there is a separate hash nohist_scantrondata that contains extra
4458: correction information that isn't representable in the bubble sheet
4459: file (see &scantron_getfile() for more information)
4460:
4461: After all scanlines are either valid, marked as valid or skipped, then
4462: foreach line foreach problem in the picked sequence, an ssi request is
4463: made that simulates a user submitting their selected letter(s) against
4464: the homework problem.
