4663: =head1 Bubble sheet grading routines
4664:
1.424 albertel 4665: For this documentation:
4666:
4667: 'scanline' refers to the full line of characters
4668: from the file that we are parsing that represents one entire sheet
4669:
4670: 'bubble line' refers to the data
4671: representing the line of bubbles that are on the physical bubble sheet
4672:
4673:
4674: The overall process is that a scanned in bubble sheet data is uploaded
4675: into a course. When a user wants to grade, they select a
4676: sequence/folder of resources, a file of bubble sheet info, and pick
4677: one of the predefined configurations for what each scanline looks
4678: like.
4679:
4680: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4681: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4682: because too light bubbling), 'double bubble' (each bubble line should
4683: have no more that one letter picked), invalid or duplicated CODE,
4684: invalid student ID
4685:
4686: If the CODE option is used that determines the randomization of the
4687: homework problems, either way the student ID is looked up into a
4688: username:domain.
4689:
4690: During the validation phase the instructor can choose to skip scanlines.
4691:
1.435 foxr 4692: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4693:
4694: scantron_original_filename (unmodified original file)
4695: scantron_corrected_filename (file where the corrected information has replaced the original information)
4696: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4697:
4698: Also there is a separate hash nohist_scantrondata that contains extra
4699: correction information that isn't representable in the bubble sheet
4700: file (see &scantron_getfile() for more information)
4701:
4702: After all scanlines are either valid, marked as valid or skipped, then
4703: foreach line foreach problem in the picked sequence, an ssi request is
4704: made that simulates a user submitting their selected letter(s) against
4705: the homework problem.
