4531: =head1 Bubble sheet grading routines
4532:
1.424 albertel 4533: For this documentation:
4534:
4535: 'scanline' refers to the full line of characters
4536: from the file that we are parsing that represents one entire sheet
4537:
4538: 'bubble line' refers to the data
4539: representing the line of bubbles that are on the physical bubble sheet
4540:
4541:
4542: The overall process is that a scanned in bubble sheet data is uploaded
4543: into a course. When a user wants to grade, they select a
4544: sequence/folder of resources, a file of bubble sheet info, and pick
4545: one of the predefined configurations for what each scanline looks
4546: like.
4547:
4548: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4549: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4550: because too light bubbling), 'double bubble' (each bubble line should
4551: have no more that one letter picked), invalid or duplicated CODE,
4552: invalid student ID
4553:
4554: If the CODE option is used that determines the randomization of the
4555: homework problems, either way the student ID is looked up into a
4556: username:domain.
4557:
4558: During the validation phase the instructor can choose to skip scanlines.
4559:
1.435 foxr 4560: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4561:
4562: scantron_original_filename (unmodified original file)
4563: scantron_corrected_filename (file where the corrected information has replaced the original information)
4564: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4565:
4566: Also there is a separate hash nohist_scantrondata that contains extra
4567: correction information that isn't representable in the bubble sheet
4568: file (see &scantron_getfile() for more information)
4569:
4570: After all scanlines are either valid, marked as valid or skipped, then
4571: foreach line foreach problem in the picked sequence, an ssi request is
4572: made that simulates a user submitting their selected letter(s) against
4573: the homework problem.
