4562: =head1 Bubble sheet grading routines
4563:
4564: For this documentation:
4565:
4566: 'scanline' refers to the full line of characters
4567: from the file that we are parsing that represents one entire sheet
4568:
4569: 'bubble line' refers to the data
4570: representing the line of bubbles that are on the physical bubble sheet
4571:
4572:
4573: The overall process is that a scanned in bubble sheet data is uploaded
4574: into a course. When a user wants to grade, they select a
4575: sequence/folder of resources, a file of bubble sheet info, and pick
4576: one of the predefined configurations for what each scanline looks
4577: like.
4578:
4579: Next each scanline is checked for any errors of either 'missing
4580: bubbles' (it's an error because it may have been mis-scanned
4581: because too light bubbling), 'double bubble' (each bubble line should
4582: have no more that one letter picked), invalid or duplicated CODE,
4583: invalid student ID
4584:
4585: If the CODE option is used that determines the randomization of the
4586: homework problems, either way the student ID is looked up into a
4587: username:domain.
4588:
4589: During the validation phase the instructor can choose to skip scanlines.
4590:
4591: After the validation phase, there are now 3 bubble sheet files
4592:
4593: scantron_original_filename (unmodified original file)
4594: scantron_corrected_filename (file where the corrected information has replaced the original information)
4595: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4596:
4597: Also there is a separate hash nohist_scantrondata that contains extra
4598: correction information that isn't representable in the bubble sheet
4599: file (see &scantron_getfile() for more information)
4600:
4601: After all scanlines are either valid, marked as valid or skipped, then
4602: foreach line foreach problem in the picked sequence, an ssi request is
4603: made that simulates a user submitting their selected letter(s) against
4604: the homework problem.
