4416: =head1 Bubble sheet grading routines
4417:
1.424 albertel 4418: For this documentation:
4419:
4420: 'scanline' refers to the full line of characters
4421: from the file that we are parsing that represents one entire sheet
4422:
4423: 'bubble line' refers to the data
4424: representing the line of bubbles that are on the physical bubble sheet
4425:
4426:
4427: The overall process is that a scanned in bubble sheet data is uploaded
4428: into a course. When a user wants to grade, they select a
4429: sequence/folder of resources, a file of bubble sheet info, and pick
4430: one of the predefined configurations for what each scanline looks
4431: like.
4432:
4433: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4434: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4435: because too light bubbling), 'double bubble' (each bubble line should
4436: have no more that one letter picked), invalid or duplicated CODE,
4437: invalid student ID
4438:
4439: If the CODE option is used that determines the randomization of the
4440: homework problems, either way the student ID is looked up into a
4441: username:domain.
4442:
4443: During the validation phase the instructor can choose to skip scanlines.
4444:
1.435 foxr 4445: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4446:
4447: scantron_original_filename (unmodified original file)
4448: scantron_corrected_filename (file where the corrected information has replaced the original information)
4449: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4450:
4451: Also there is a separate hash nohist_scantrondata that contains extra
4452: correction information that isn't representable in the bubble sheet
4453: file (see &scantron_getfile() for more information)
4454:
4455: After all scanlines are either valid, marked as valid or skipped, then
4456: foreach line foreach problem in the picked sequence, an ssi request is
4457: made that simulates a user submitting their selected letter(s) against
4458: the homework problem.
