4524: =head1 Bubble sheet grading routines
4525:
1.424 albertel 4526: For this documentation:
4527:
4528: 'scanline' refers to the full line of characters
4529: from the file that we are parsing that represents one entire sheet
4530:
4531: 'bubble line' refers to the data
4532: representing the line of bubbles that are on the physical bubble sheet
4533:
4534:
4535: The overall process is that a scanned in bubble sheet data is uploaded
4536: into a course. When a user wants to grade, they select a
4537: sequence/folder of resources, a file of bubble sheet info, and pick
4538: one of the predefined configurations for what each scanline looks
4539: like.
4540:
4541: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4542: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4543: because too light bubbling), 'double bubble' (each bubble line should
4544: have no more that one letter picked), invalid or duplicated CODE,
4545: invalid student ID
4546:
4547: If the CODE option is used that determines the randomization of the
4548: homework problems, either way the student ID is looked up into a
4549: username:domain.
4550:
4551: During the validation phase the instructor can choose to skip scanlines.
4552:
1.435 foxr 4553: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4554:
4555: scantron_original_filename (unmodified original file)
4556: scantron_corrected_filename (file where the corrected information has replaced the original information)
4557: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4558:
4559: Also there is a separate hash nohist_scantrondata that contains extra
4560: correction information that isn't representable in the bubble sheet
4561: file (see &scantron_getfile() for more information)
4562:
4563: After all scanlines are either valid, marked as valid or skipped, then
4564: foreach line foreach problem in the picked sequence, an ssi request is
4565: made that simulates a user submitting their selected letter(s) against
4566: the homework problem.
