4404: =head1 Bubble sheet grading routines
4405:
1.424 albertel 4406: For this documentation:
4407:
4408: 'scanline' refers to the full line of characters
4409: from the file that we are parsing that represents one entire sheet
4410:
4411: 'bubble line' refers to the data
4412: representing the line of bubbles that are on the physical bubble sheet
4413:
4414:
4415: The overall process is that a scanned in bubble sheet data is uploaded
4416: into a course. When a user wants to grade, they select a
4417: sequence/folder of resources, a file of bubble sheet info, and pick
4418: one of the predefined configurations for what each scanline looks
4419: like.
4420:
4421: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4422: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4423: because too light bubbling), 'double bubble' (each bubble line should
4424: have no more that one letter picked), invalid or duplicated CODE,
4425: invalid student ID
4426:
4427: If the CODE option is used that determines the randomization of the
4428: homework problems, either way the student ID is looked up into a
4429: username:domain.
4430:
4431: During the validation phase the instructor can choose to skip scanlines.
4432:
1.435 foxr 4433: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4434:
4435: scantron_original_filename (unmodified original file)
4436: scantron_corrected_filename (file where the corrected information has replaced the original information)
4437: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4438:
4439: Also there is a separate hash nohist_scantrondata that contains extra
4440: correction information that isn't representable in the bubble sheet
4441: file (see &scantron_getfile() for more information)
4442:
4443: After all scanlines are either valid, marked as valid or skipped, then
4444: foreach line foreach problem in the picked sequence, an ssi request is
4445: made that simulates a user submitting their selected letter(s) against
4446: the homework problem.
