1.424 albertel 4825: For this documentation:
4826:
4827: 'scanline' refers to the full line of characters
4828: from the file that we are parsing that represents one entire sheet
4829:
4830: 'bubble line' refers to the data
4831: representing the line of bubbles that are on the physical bubble sheet
4832:
4833:
4834: The overall process is that a scanned in bubble sheet data is uploaded
4835: into a course. When a user wants to grade, they select a
4836: sequence/folder of resources, a file of bubble sheet info, and pick
4837: one of the predefined configurations for what each scanline looks
4838: like.
4839:
4840: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4841: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4842: because too light bubbling), 'double bubble' (each bubble line should
4843: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4844: invalid student/employee ID
1.424 albertel 4845:
4846: If the CODE option is used that determines the randomization of the
1.556 weissno 4847: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4848: username:domain.
4849:
4850: During the validation phase the instructor can choose to skip scanlines.
4851:
1.435 foxr 4852: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4853:
4854: scantron_original_filename (unmodified original file)
4855: scantron_corrected_filename (file where the corrected information has replaced the original information)
4856: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4857:
4858: Also there is a separate hash nohist_scantrondata that contains extra
4859: correction information that isn't representable in the bubble sheet
4860: file (see &scantron_getfile() for more information)
4861:
4862: After all scanlines are either valid, marked as valid or skipped, then
4863: foreach line foreach problem in the picked sequence, an ssi request is
4864: made that simulates a user submitting their selected letter(s) against
4865: the homework problem.

9504: =head1 NAME
9505:
9506: Apache::grades
9507:
9508: =head1 SYNOPSIS
9509:
9510: Handles the viewing of grades.
9511:
9512: This is part of the LearningOnline Network with CAPA project
9513: described at http://www.lon-capa.org.
9514:
9515: =head1 OVERVIEW
9516:
9517: Do an ssi with retries:
9518: While I'd love to factor out this with the vesrion in lonprintout,
9519: that would either require a data coupling between modules, which I refuse to perpetuate (there's quite enough of that already), or would require the invention of another infrastructure
9520: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9521:
9522: At least the logic that drives this has been pulled out into loncommon.
9523:
9524:
9525:
9526: ssi_with_retries - Does the server side include of a resource.
9527: if the ssi call returns an error we'll retry it up to
9528: the number of times requested by the caller.
9529: If we still have a proble, no text is appended to the
9530: output and we set some global variables.
9531: to indicate to the caller an SSI error occurred.
9532: All of this is supposed to deal with the issues described
9533: in LonCAPA BZ 5631 see:
9534: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9535: by informing the user that this happened.
9536:
9537: Parameters:
9538: resource - The resource to include. This is passed directly, without
9539: interpretation to lonnet::ssi.
9540: form - The form hash parameters that guide the interpretation of the resource
9541:
9542: retries - Number of retries allowed before giving up completely.
9543: Returns:
9544: On success, returns the rendered resource identified by the resource parameter.
9545: Side Effects:
9546: The following global variables can be set:
9547: ssi_error - If an unrecoverable error occurred this becomes true.
9548: It is up to the caller to initialize this to false
9549: if desired.
9550: ssi_error_resource - If an unrecoverable error occurred, this is the value
9551: of the resource that could not be rendered by the ssi
9552: call.
9553: ssi_error_message - The error string fetched from the ssi response
9554: in the event of an error.

9571: $r - Apache request object
9572: $i - number of the current scanline
9573: $scan_record - hash ref as returned from &scantron_parse_scanline()
9574: $scan_config - hash ref as returned from &get_scantron_config()

9579: 'duplicateID', 'incorrectID'
9580: $arg - extra information needed
9581: For errors:
9582: - duplicateID - paper number that this studentID was seen before on
9583: - duplicateCODE - array ref of the paper numbers this CODE was
9584: seen on before
9585: - incorrectCODE - current incorrect CODE
9586: - doublebubble - array ref of the bubble lines that have double
9587: bubble errors

9589: bubble errors

1.582 raeburn 9593: Arguments:
9594: $nav_error - Reference to scalar which is a flag to indicate a
9595: failure to retrieve a navmap object.
9596: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9597: calling routine should trap the error condition and display the warning
9598: found in &navmap_errormsg().
9599:
1.649 raeburn 9600: $scantron_config - Reference to bubblesheet format configuration hash.
9601:
1.531 jms 9602: Returns the maximum number of bubble lines that are expected to
9603: occur. Does this by walking the selected sequence rendering the

9606:
9607: Caches the results to $env{'form.scantron_maxbubble'},

9609: $env{'form.scantron.first_bubble_line.n'} and
9610: $env{"form.scantron.sub_bubblelines.n"}
9611: which are the total number of bubble, lines, the number of bubble
9612: lines for response n and number of the first bubble line for response n,

9623: =item scantron_process_students() :
9624:
9625: Routine that does the actual grading of the bubble sheet information.
9626:
9627: The parsed scanline hash is added to %env
9628:
9629: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9630: foreach resource , with the form data of
9631:
9632: 'submitted' =>'scantron'
9633: 'grade_target' =>'grade',

9637: 'grade_symb' => symb of resource to grade
9638:
9639: This triggers a grading pass. The problem grading code takes care
