4501: =head1 Bubble sheet grading routines
4502:
1.424 albertel 4503: For this documentation:
4504:
4505: 'scanline' refers to the full line of characters
4506: from the file that we are parsing that represents one entire sheet
4507:
4508: 'bubble line' refers to the data
4509: representing the line of bubbles that are on the physical bubble sheet
4510:
4511:
4512: The overall process is that a scanned in bubble sheet data is uploaded
4513: into a course. When a user wants to grade, they select a
4514: sequence/folder of resources, a file of bubble sheet info, and pick
4515: one of the predefined configurations for what each scanline looks
4516: like.
4517:
4518: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4519: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4520: because too light bubbling), 'double bubble' (each bubble line should
4521: have no more that one letter picked), invalid or duplicated CODE,
4522: invalid student ID
4523:
4524: If the CODE option is used that determines the randomization of the
4525: homework problems, either way the student ID is looked up into a
4526: username:domain.
4527:
4528: During the validation phase the instructor can choose to skip scanlines.
4529:
1.435 foxr 4530: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4531:
4532: scantron_original_filename (unmodified original file)
4533: scantron_corrected_filename (file where the corrected information has replaced the original information)
4534: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4535:
4536: Also there is a separate hash nohist_scantrondata that contains extra
4537: correction information that isn't representable in the bubble sheet
4538: file (see &scantron_getfile() for more information)
4539:
4540: After all scanlines are either valid, marked as valid or skipped, then
4541: foreach line foreach problem in the picked sequence, an ssi request is
4542: made that simulates a user submitting their selected letter(s) against
4543: the homework problem.
