4377: =head1 Bubble sheet grading routines
4378:
1.424 albertel 4379: For this documentation:
4380:
4381: 'scanline' refers to the full line of characters
4382: from the file that we are parsing that represents one entire sheet
4383:
4384: 'bubble line' refers to the data
4385: representing the line of bubbles that are on the physical bubble sheet
4386:
4387:
4388: The overall process is that a scanned in bubble sheet data is uploaded
4389: into a course. When a user wants to grade, they select a
4390: sequence/folder of resources, a file of bubble sheet info, and pick
4391: one of the predefined configurations for what each scanline looks
4392: like.
4393:
4394: Next each scanline is checked for any errors of either 'missing
4395: bubbles' (it's an error because it may have been missed scanned
4396: because too light bubbling), 'double bubble' (each bubble line should
4397: have no more that one letter picked), invalid or duplicated CODE,
4398: invalid student ID
4399:
4400: If the CODE option is used that determines the randomization of the
4401: homework problems, either way the student ID is looked up into a
4402: username:domain.
4403:
4404: During the validation phase the instructor can choose to skip scanlines.
4405:
4406: After the validation phase, there is now 3 bubble sheet files
4407:
4408: scantron_original_filename (unmodified original file)
4409: scantron_corrected_filename (file where the corrected information has replaced the original information)
4410: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4411:
4412: Also there is a separate hash nohist_scantrondata that contains extra
4413: correction information that isn't representable in the bubble sheet
4414: file (see &scantron_getfile() for more information)
4415:
4416: After all scanlines are either valid, marked as valid or skipped, then
4417: foreach line foreach problem in the picked sequence, an ssi request is
4418: made that simulates a user submitting their selected letter(s) against
4419: the homework problem.
