4497: =head1 Bubble sheet grading routines
4498:
1.424 albertel 4499: For this documentation:
4500:
4501: 'scanline' refers to the full line of characters
4502: from the file that we are parsing that represents one entire sheet
4503:
4504: 'bubble line' refers to the data
4505: representing the line of bubbles that are on the physical bubble sheet
4506:
4507:
4508: The overall process is that a scanned in bubble sheet data is uploaded
4509: into a course. When a user wants to grade, they select a
4510: sequence/folder of resources, a file of bubble sheet info, and pick
4511: one of the predefined configurations for what each scanline looks
4512: like.
4513:
4514: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4515: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4516: because too light bubbling), 'double bubble' (each bubble line should
4517: have no more that one letter picked), invalid or duplicated CODE,
4518: invalid student ID
4519:
4520: If the CODE option is used that determines the randomization of the
4521: homework problems, either way the student ID is looked up into a
4522: username:domain.
4523:
4524: During the validation phase the instructor can choose to skip scanlines.
4525:
1.435 foxr 4526: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4527:
4528: scantron_original_filename (unmodified original file)
4529: scantron_corrected_filename (file where the corrected information has replaced the original information)
4530: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4531:
4532: Also there is a separate hash nohist_scantrondata that contains extra
4533: correction information that isn't representable in the bubble sheet
4534: file (see &scantron_getfile() for more information)
4535:
4536: After all scanlines are either valid, marked as valid or skipped, then
4537: foreach line foreach problem in the picked sequence, an ssi request is
4538: made that simulates a user submitting their selected letter(s) against
4539: the homework problem.
