4407: =head1 Bubble sheet grading routines
4408:
1.424 albertel 4409: For this documentation:
4410:
4411: 'scanline' refers to the full line of characters
4412: from the file that we are parsing that represents one entire sheet
4413:
4414: 'bubble line' refers to the data
4415: representing the line of bubbles that are on the physical bubble sheet
4416:
4417:
4418: The overall process is that a scanned in bubble sheet data is uploaded
4419: into a course. When a user wants to grade, they select a
4420: sequence/folder of resources, a file of bubble sheet info, and pick
4421: one of the predefined configurations for what each scanline looks
4422: like.
4423:
4424: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4425: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4426: because too light bubbling), 'double bubble' (each bubble line should
4427: have no more that one letter picked), invalid or duplicated CODE,
4428: invalid student ID
4429:
4430: If the CODE option is used that determines the randomization of the
4431: homework problems, either way the student ID is looked up into a
4432: username:domain.
4433:
4434: During the validation phase the instructor can choose to skip scanlines.
4435:
1.435 foxr 4436: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4437:
4438: scantron_original_filename (unmodified original file)
4439: scantron_corrected_filename (file where the corrected information has replaced the original information)
4440: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4441:
4442: Also there is a separate hash nohist_scantrondata that contains extra
4443: correction information that isn't representable in the bubble sheet
4444: file (see &scantron_getfile() for more information)
4445:
4446: After all scanlines are either valid, marked as valid or skipped, then
4447: foreach line foreach problem in the picked sequence, an ssi request is
4448: made that simulates a user submitting their selected letter(s) against
4449: the homework problem.
