4358: =head1 Bubble sheet grading routines
4359:
1.424 albertel 4360: For this documentation:
4361:
4362: 'scanline' refers to the full line of characters
4363: from the file that we are parsing that represents one entire sheet
4364:
4365: 'bubble line' refers to the data
4366: representing the line of bubbles that are on the physical bubble sheet
4367:
4368:
4369: The overall process is that a scanned in bubble sheet data is uploaded
4370: into a course. When a user wants to grade, they select a
4371: sequence/folder of resources, a file of bubble sheet info, and pick
4372: one of the predefined configurations for what each scanline looks
4373: like.
4374:
4375: Next each scanline is checked for any errors of either 'missing
4376: bubbles' (it's an error because it may have been missed scanned
4377: because too light bubbling), 'double bubble' (each bubble line should
4378: have no more that one letter picked), invalid or duplicated CODE,
4379: invalid student ID
4380:
4381: If the CODE option is used that determines the randomization of the
4382: homework problems, either way the student ID is looked up into a
4383: username:domain.
4384:
4385: During the validation phase the instructor can choose to skip scanlines.
4386:
4387: After the validation phase, there is now 3 bubble sheet files
4388:
4389: scantron_original_filename (unmodified original file)
4390: scantron_corrected_filename (file where the corrected information has replaced the original information)
4391: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4392:
4393: Also there is a separate hash nohist_scantrondata that contains extra
4394: correction information that isn't representable in the bubble sheet
4395: file (see &scantron_getfile() for more information)
4396:
4397: After all scanlines are either valid, marked as valid or skipped, then
4398: foreach line foreach problem in the picked sequence, an ssi request is
4399: made that simulates a user submitting their selected letter(s) against
4400: the homework problem.
