4667: =head1 Bubble sheet grading routines
4668:
1.424 albertel 4669: For this documentation:
4670:
4671: 'scanline' refers to the full line of characters
4672: from the file that we are parsing that represents one entire sheet
4673:
4674: 'bubble line' refers to the data
4675: representing the line of bubbles that are on the physical bubble sheet
4676:
4677:
4678: The overall process is that a scanned in bubble sheet data is uploaded
4679: into a course. When a user wants to grade, they select a
4680: sequence/folder of resources, a file of bubble sheet info, and pick
4681: one of the predefined configurations for what each scanline looks
4682: like.
4683:
4684: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4685: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4686: because too light bubbling), 'double bubble' (each bubble line should
4687: have no more that one letter picked), invalid or duplicated CODE,
4688: invalid student ID
4689:
4690: If the CODE option is used that determines the randomization of the
4691: homework problems, either way the student ID is looked up into a
4692: username:domain.
4693:
4694: During the validation phase the instructor can choose to skip scanlines.
4695:
1.435 foxr 4696: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4697:
4698: scantron_original_filename (unmodified original file)
4699: scantron_corrected_filename (file where the corrected information has replaced the original information)
4700: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4701:
4702: Also there is a separate hash nohist_scantrondata that contains extra
4703: correction information that isn't representable in the bubble sheet
4704: file (see &scantron_getfile() for more information)
4705:
4706: After all scanlines are either valid, marked as valid or skipped, then
4707: foreach line foreach problem in the picked sequence, an ssi request is
4708: made that simulates a user submitting their selected letter(s) against
4709: the homework problem.
