4398: =head1 Bubble sheet grading routines
4399:
4400: For this documentation:
4401:
4402: 'scanline' refers to the full line of characters
4403: from the file that we are parsing that represents one entire sheet
4404:
4405: 'bubble line' refers to the data
4406: representing the line of bubbles that are on the physical bubble sheet
4407:
4408:
4409: The overall process is that a scanned in bubble sheet data is uploaded
4410: into a course. When a user wants to grade, they select a
4411: sequence/folder of resources, a file of bubble sheet info, and pick
4412: one of the predefined configurations for what each scanline looks
4413: like.
4414:
4415: Next each scanline is checked for any errors of either 'missing
4416: bubbles' (it's an error because it may have been missed scanned
4417: because too light bubbling), 'double bubble' (each bubble line should
4418: have no more that one letter picked), invalid or duplicated CODE,
4419: invalid student ID
4420:
4421: If the CODE option is used that determines the randomization of the
4422: homework problems, either way the student ID is looked up into a
4423: username:domain.
4424:
4425: During the validation phase the instructor can choose to skip scanlines.
4426:
4427: After the validation phase, there is now 3 bubble sheet files
4428:
4429: scantron_original_filename (unmodified original file)
4430: scantron_corrected_filename (file where the corrected information has replaced the original information)
