4530: =head1 Bubble sheet grading routines
4531:
1.424 albertel 4532: For this documentation:
4533:
4534: 'scanline' refers to the full line of characters
4535: from the file that we are parsing that represents one entire sheet
4536:
4537: 'bubble line' refers to the data
4538: representing the line of bubbles that are on the physical bubble sheet
4539:
4540:
4541: The overall process is that a scanned in bubble sheet data is uploaded
4542: into a course. When a user wants to grade, they select a
4543: sequence/folder of resources, a file of bubble sheet info, and pick
4544: one of the predefined configurations for what each scanline looks
4545: like.
4546:
4547: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4548: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4549: because too light bubbling), 'double bubble' (each bubble line should
4550: have no more that one letter picked), invalid or duplicated CODE,
4551: invalid student ID
4552:
4553: If the CODE option is used that determines the randomization of the
4554: homework problems, either way the student ID is looked up into a
4555: username:domain.
4556:
4557: During the validation phase the instructor can choose to skip scanlines.
4558:
1.435 foxr 4559: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4560:
4561: scantron_original_filename (unmodified original file)
4562: scantron_corrected_filename (file where the corrected information has replaced the original information)
4563: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4564:
4565: Also there is a separate hash nohist_scantrondata that contains extra
4566: correction information that isn't representable in the bubble sheet
4567: file (see &scantron_getfile() for more information)
4568:
4569: After all scanlines are either valid, marked as valid or skipped, then
4570: foreach line foreach problem in the picked sequence, an ssi request is
4571: made that simulates a user submitting their selected letter(s) against
4572: the homework problem.
