4364: =head1 Bubble sheet grading routines
4365:
4366: For this documentation:
4367:
4368: 'scanline' refers to the full line of characters
4369: from the file that we are parsing that represents one entire sheet
4370:
4371: 'bubble line' refers to the data
4372: representing the line of bubbles that are on the physical bubble sheet
4373:
4374:
4375: The overall process is that a scanned in bubble sheet data is uploaded
4376: into a course. When a user wants to grade, they select a
4377: sequence/folder of resources, a file of bubble sheet info, and pick
4378: one of the predefined configurations for what each scanline looks
4379: like.
4380:
4381: Next each scanline is checked for any errors of either 'missing
4382: bubbles' (it's an error because it may have been missed scanned
4383: because too light bubbling), 'double bubble' (each bubble line should
4384: have no more that one letter picked), invalid or duplicated CODE,
4385: invalid student ID
4386:
4387: If the CODE option is used that determines the randomization of the
4388: homework problems, either way the student ID is looked up into a
4389: username:domain.
4390:
4391: During the validation phase the instructor can choose to skip scanlines.
4392:
4393: After the validation phase, there is now 3 bubble sheet files
4394:
4395: scantron_original_filename (unmodified original file)
4396: scantron_corrected_filename (file where the corrected information has replaced the original information)
4397: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4398:
4399: Also there is a separate hash nohist_scantrondata that contains extra
4400: correction information that isn't representable in the bubble sheet
4401: file (see &scantron_getfile() for more information)
4402:
4403: After all scanlines are either valid, marked as valid or skipped, then
4404: foreach line foreach problem in the picked sequence, an ssi request is
4405: made that simulates a user submitting their selected letter(s) against
4406: the homework problem.
