4825:
1.424 albertel 4826: For this documentation:
4827:
4828: 'scanline' refers to the full line of characters
4829: from the file that we are parsing that represents one entire sheet
4830:
4831: 'bubble line' refers to the data
4832: representing the line of bubbles that are on the physical bubble sheet
4833:
4834:
4835: The overall process is that a scanned in bubble sheet data is uploaded
4836: into a course. When a user wants to grade, they select a
4837: sequence/folder of resources, a file of bubble sheet info, and pick
4838: one of the predefined configurations for what each scanline looks
4839: like.
4840:
4841: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4842: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4843: because too light bubbling), 'double bubble' (each bubble line should
4844: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4845: invalid student/employee ID
1.424 albertel 4846:
4847: If the CODE option is used that determines the randomization of the
1.556 weissno 4848: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4849: username:domain.
4850:
4851: During the validation phase the instructor can choose to skip scanlines.
4852:
1.435 foxr 4853: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4854:
4855: scantron_original_filename (unmodified original file)
4856: scantron_corrected_filename (file where the corrected information has replaced the original information)
4857: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4858:
4859: Also there is a separate hash nohist_scantrondata that contains extra
4860: correction information that isn't representable in the bubble sheet
4861: file (see &scantron_getfile() for more information)
4862:
4863: After all scanlines are either valid, marked as valid or skipped, then
4864: foreach line foreach problem in the picked sequence, an ssi request is
4865: made that simulates a user submitting their selected letter(s) against
4866: the homework problem.

9505: =head1 NAME
9506:
9507: Apache::grades
9508:
9509: =head1 SYNOPSIS
9510:
9511: Handles the viewing of grades.
9512:
9513: This is part of the LearningOnline Network with CAPA project
9514: described at http://www.lon-capa.org.
9515:
9516: =head1 OVERVIEW
9517:
9518: Do an ssi with retries:
9519: While I'd love to factor out this with the vesrion in lonprintout,
9520: 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
9521: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9522:
9523: At least the logic that drives this has been pulled out into loncommon.
9524:
9525:
9526:
9527: ssi_with_retries - Does the server side include of a resource.
9528: if the ssi call returns an error we'll retry it up to
9529: the number of times requested by the caller.
9530: If we still have a proble, no text is appended to the
9531: output and we set some global variables.
9532: to indicate to the caller an SSI error occurred.
9533: All of this is supposed to deal with the issues described
9534: in LonCAPA BZ 5631 see:
9535: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9536: by informing the user that this happened.
9537:
9538: Parameters:
9539: resource - The resource to include. This is passed directly, without
9540: interpretation to lonnet::ssi.
9541: form - The form hash parameters that guide the interpretation of the resource
9542:
9543: retries - Number of retries allowed before giving up completely.
9544: Returns:
9545: On success, returns the rendered resource identified by the resource parameter.
9546: Side Effects:
9547: The following global variables can be set:
9548: ssi_error - If an unrecoverable error occurred this becomes true.
9549: It is up to the caller to initialize this to false
9550: if desired.
9551: ssi_error_resource - If an unrecoverable error occurred, this is the value
9552: of the resource that could not be rendered by the ssi
9553: call.
9554: ssi_error_message - The error string fetched from the ssi response
9555: in the event of an error.

9572: $r - Apache request object
9573: $i - number of the current scanline
9574: $scan_record - hash ref as returned from &scantron_parse_scanline()
9575: $scan_config - hash ref as returned from &get_scantron_config()

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

9590: bubble errors

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

9610: $env{'form.scantron.first_bubble_line.n'} and
9611: $env{"form.scantron.sub_bubblelines.n"}
9612: which are the total number of bubble, lines, the number of bubble
9613: lines for response n and number of the first bubble line for response n,

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