4413: =head1 Bubble sheet grading routines
4414:
1.424 albertel 4415: For this documentation:
4416:
4417: 'scanline' refers to the full line of characters
4418: from the file that we are parsing that represents one entire sheet
4419:
4420: 'bubble line' refers to the data
4421: representing the line of bubbles that are on the physical bubble sheet
4422:
4423:
4424: The overall process is that a scanned in bubble sheet data is uploaded
4425: into a course. When a user wants to grade, they select a
4426: sequence/folder of resources, a file of bubble sheet info, and pick
4427: one of the predefined configurations for what each scanline looks
4428: like.
4429:
4430: Next each scanline is checked for any errors of either 'missing
4431: bubbles' (it's an error because it may have been missed scanned
4432: because too light bubbling), 'double bubble' (each bubble line should
4433: have no more that one letter picked), invalid or duplicated CODE,
4434: invalid student ID
4435:
4436: If the CODE option is used that determines the randomization of the
4437: homework problems, either way the student ID is looked up into a
4438: username:domain.
4439:
4440: During the validation phase the instructor can choose to skip scanlines.
4441:
4442: After the validation phase, there is now 3 bubble sheet files
4443:
4444: scantron_original_filename (unmodified original file)
4445: scantron_corrected_filename (file where the corrected information has replaced the original information)
4446: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4447:
4448: Also there is a separate hash nohist_scantrondata that contains extra
4449: correction information that isn't representable in the bubble sheet
4450: file (see &scantron_getfile() for more information)
4451:
4452: After all scanlines are either valid, marked as valid or skipped, then
4453: foreach line foreach problem in the picked sequence, an ssi request is
4454: made that simulates a user submitting their selected letter(s) against
4455: the homework problem.
