4568: =head1 Bubble sheet grading routines
4569:
1.424 albertel 4570: For this documentation:
4571:
4572: 'scanline' refers to the full line of characters
4573: from the file that we are parsing that represents one entire sheet
4574:
4575: 'bubble line' refers to the data
4576: representing the line of bubbles that are on the physical bubble sheet
4577:
4578:
4579: The overall process is that a scanned in bubble sheet data is uploaded
4580: into a course. When a user wants to grade, they select a
4581: sequence/folder of resources, a file of bubble sheet info, and pick
4582: one of the predefined configurations for what each scanline looks
4583: like.
4584:
4585: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4586: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4587: because too light bubbling), 'double bubble' (each bubble line should
4588: have no more that one letter picked), invalid or duplicated CODE,
4589: invalid student ID
4590:
4591: If the CODE option is used that determines the randomization of the
4592: homework problems, either way the student ID is looked up into a
4593: username:domain.
4594:
4595: During the validation phase the instructor can choose to skip scanlines.
4596:
1.435 foxr 4597: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4598:
4599: scantron_original_filename (unmodified original file)
4600: scantron_corrected_filename (file where the corrected information has replaced the original information)
4601: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4602:
4603: Also there is a separate hash nohist_scantrondata that contains extra
4604: correction information that isn't representable in the bubble sheet
4605: file (see &scantron_getfile() for more information)
4606:
4607: After all scanlines are either valid, marked as valid or skipped, then
4608: foreach line foreach problem in the picked sequence, an ssi request is
4609: made that simulates a user submitting their selected letter(s) against
4610: the homework problem.
