4367: =head1 Bubble sheet grading routines
4368:
4369: For this documentation:
4370:
4371: 'scanline' refers to the full line of characters
4372: from the file that we are parsing that represents one entire sheet
4373:
4374: 'bubble line' refers to the data
4375: representing the line of bubbles that are on the physical bubble sheet
4376:
4377:
4378: The overall process is that a scanned in bubble sheet data is uploaded
4379: into a course. When a user wants to grade, they select a
4380: sequence/folder of resources, a file of bubble sheet info, and pick
4381: one of the predefined configurations for what each scanline looks
4382: like.
4383:
4384: Next each scanline is checked for any errors of either 'missing
4385: bubbles' (it's an error because it may have been missed scanned
4386: because too light bubbling), 'double bubble' (each bubble line should
4387: have no more that one letter picked), invalid or duplicated CODE,
4388: invalid student ID
4389:
4390: If the CODE option is used that determines the randomization of the
4391: homework problems, either way the student ID is looked up into a
4392: username:domain.
4393:
4394: During the validation phase the instructor can choose to skip scanlines.
4395:
4396: After the validation phase, there is now 3 bubble sheet files
4397:
4398: scantron_original_filename (unmodified original file)
4399: scantron_corrected_filename (file where the corrected information has replaced the original information)
4400: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4401:
4402: Also there is a separate hash nohist_scantrondata that contains extra
4403: correction information that isn't representable in the bubble sheet
4404: file (see &scantron_getfile() for more information)
4405:
4406: After all scanlines are either valid, marked as valid or skipped, then
4407: foreach line foreach problem in the picked sequence, an ssi request is
4408: made that simulates a user submitting their selected letter(s) against
4409: the homework problem.
