4499: =head1 Bubble sheet grading routines
4500:
1.424 albertel 4501: For this documentation:
4502:
4503: 'scanline' refers to the full line of characters
4504: from the file that we are parsing that represents one entire sheet
4505:
4506: 'bubble line' refers to the data
4507: representing the line of bubbles that are on the physical bubble sheet
4508:
4509:
4510: The overall process is that a scanned in bubble sheet data is uploaded
4511: into a course. When a user wants to grade, they select a
4512: sequence/folder of resources, a file of bubble sheet info, and pick
4513: one of the predefined configurations for what each scanline looks
4514: like.
4515:
4516: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4517: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4518: because too light bubbling), 'double bubble' (each bubble line should
4519: have no more that one letter picked), invalid or duplicated CODE,
4520: invalid student ID
4521:
4522: If the CODE option is used that determines the randomization of the
4523: homework problems, either way the student ID is looked up into a
4524: username:domain.
4525:
4526: During the validation phase the instructor can choose to skip scanlines.
4527:
1.435 foxr 4528: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4529:
4530: scantron_original_filename (unmodified original file)
4531: scantron_corrected_filename (file where the corrected information has replaced the original information)
4532: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4533:
4534: Also there is a separate hash nohist_scantrondata that contains extra
4535: correction information that isn't representable in the bubble sheet
4536: file (see &scantron_getfile() for more information)
4537:
4538: After all scanlines are either valid, marked as valid or skipped, then
4539: foreach line foreach problem in the picked sequence, an ssi request is
4540: made that simulates a user submitting their selected letter(s) against
4541: the homework problem.
