4366: =head1 Bubble sheet grading routines
4367:
1.424 albertel 4368: For this documentation:
4369:
4370: 'scanline' refers to the full line of characters
4371: from the file that we are parsing that represents one entire sheet
4372:
4373: 'bubble line' refers to the data
4374: representing the line of bubbles that are on the physical bubble sheet
4375:
4376:
4377: The overall process is that a scanned in bubble sheet data is uploaded
4378: into a course. When a user wants to grade, they select a
4379: sequence/folder of resources, a file of bubble sheet info, and pick
4380: one of the predefined configurations for what each scanline looks
4381: like.
4382:
4383: Next each scanline is checked for any errors of either 'missing
4384: bubbles' (it's an error because it may have been missed scanned
4385: because too light bubbling), 'double bubble' (each bubble line should
4386: have no more that one letter picked), invalid or duplicated CODE,
4387: invalid student ID
4388:
4389: If the CODE option is used that determines the randomization of the
4390: homework problems, either way the student ID is looked up into a
4391: username:domain.
4392:
4393: During the validation phase the instructor can choose to skip scanlines.
4394:
4395: After the validation phase, there is now 3 bubble sheet files
4396:
4397: scantron_original_filename (unmodified original file)
4398: scantron_corrected_filename (file where the corrected information has replaced the original information)
4399: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4400:
4401: Also there is a separate hash nohist_scantrondata that contains extra
4402: correction information that isn't representable in the bubble sheet
4403: file (see &scantron_getfile() for more information)
4404:
4405: After all scanlines are either valid, marked as valid or skipped, then
4406: foreach line foreach problem in the picked sequence, an ssi request is
4407: made that simulates a user submitting their selected letter(s) against
4408: the homework problem.
