4787:
1.424 albertel 4788: For this documentation:
4789:
4790: 'scanline' refers to the full line of characters
4791: from the file that we are parsing that represents one entire sheet
4792:
4793: 'bubble line' refers to the data
4794: representing the line of bubbles that are on the physical bubble sheet
4795:
4796:
4797: The overall process is that a scanned in bubble sheet data is uploaded
4798: into a course. When a user wants to grade, they select a
4799: sequence/folder of resources, a file of bubble sheet info, and pick
4800: one of the predefined configurations for what each scanline looks
4801: like.
4802:
4803: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4804: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4805: because too light bubbling), 'double bubble' (each bubble line should
4806: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4807: invalid student/employee ID
1.424 albertel 4808:
4809: If the CODE option is used that determines the randomization of the
1.556 weissno 4810: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4811: username:domain.
4812:
4813: During the validation phase the instructor can choose to skip scanlines.
4814:
1.435 foxr 4815: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4816:
4817: scantron_original_filename (unmodified original file)
4818: scantron_corrected_filename (file where the corrected information has replaced the original information)
4819: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4820:
4821: Also there is a separate hash nohist_scantrondata that contains extra
4822: correction information that isn't representable in the bubble sheet
4823: file (see &scantron_getfile() for more information)
4824:
4825: After all scanlines are either valid, marked as valid or skipped, then
4826: foreach line foreach problem in the picked sequence, an ssi request is
4827: made that simulates a user submitting their selected letter(s) against
4828: the homework problem.

9468: =head1 NAME
9469:
9470: Apache::grades
9471:
9472: =head1 SYNOPSIS
9473:
9474: Handles the viewing of grades.
9475:
9476: This is part of the LearningOnline Network with CAPA project
9477: described at http://www.lon-capa.org.
9478:
9479: =head1 OVERVIEW
9480:
9481: Do an ssi with retries:
9482: While I'd love to factor out this with the vesrion in lonprintout,
9483: 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
9484: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9485:
9486: At least the logic that drives this has been pulled out into loncommon.
9487:
9488:
9489:
9490: ssi_with_retries - Does the server side include of a resource.
9491: if the ssi call returns an error we'll retry it up to
9492: the number of times requested by the caller.
9493: If we still have a proble, no text is appended to the
9494: output and we set some global variables.
9495: to indicate to the caller an SSI error occurred.
9496: All of this is supposed to deal with the issues described
9497: in LonCAPA BZ 5631 see:
9498: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9499: by informing the user that this happened.
9500:
9501: Parameters:
9502: resource - The resource to include. This is passed directly, without
9503: interpretation to lonnet::ssi.
9504: form - The form hash parameters that guide the interpretation of the resource
9505:
9506: retries - Number of retries allowed before giving up completely.
9507: Returns:
9508: On success, returns the rendered resource identified by the resource parameter.
9509: Side Effects:
9510: The following global variables can be set:
9511: ssi_error - If an unrecoverable error occurred this becomes true.
9512: It is up to the caller to initialize this to false
9513: if desired.
9514: ssi_error_resource - If an unrecoverable error occurred, this is the value
9515: of the resource that could not be rendered by the ssi
9516: call.
9517: ssi_error_message - The error string fetched from the ssi response
9518: in the event of an error.

9531: Builds the interface screen to interact with the operator to fix a

9533:
9534: Arguments:
9535: $r - Apache request object
9536: $i - number of the current scanline
9537: $scan_record - hash ref as returned from &scantron_parse_scanline()
9538: $scan_config - hash ref as returned from &get_scantron_config()
9539: $line - full contents of the current scanline
9540: $error - error condition, valid values are
9541: 'incorrectCODE', 'duplicateCODE',
9542: 'doublebubble', 'missingbubble',
9543: 'duplicateID', 'incorrectID'
9544: $arg - extra information needed
9545: For errors:
9546: - duplicateID - paper number that this studentID was seen before on
9547: - duplicateCODE - array ref of the paper numbers this CODE was
9548: seen on before
9549: - incorrectCODE - current incorrect CODE
9550: - doublebubble - array ref of the bubble lines that have double
9551: bubble errors

9553: bubble errors

9555: =item scantron_get_maxbubble() :

1.582 raeburn 9557: Arguments:
9558: $nav_error - Reference to scalar which is a flag to indicate a
9559: failure to retrieve a navmap object.
9560: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9561: calling routine should trap the error condition and display the warning
9562: found in &navmap_errormsg().
9563:
1.649 ! raeburn 9564: $scantron_config - Reference to bubblesheet format configuration hash.
! 9565:
1.531 jms 9566: Returns the maximum number of bubble lines that are expected to
9567: occur. Does this by walking the selected sequence rendering the
9568: resource and then checking &Apache::lonxml::get_problem_counter()
9569: for what the current value of the problem counter is.
9570:
9571: Caches the results to $env{'form.scantron_maxbubble'},

9573: $env{'form.scantron.first_bubble_line.n'} and
9574: $env{"form.scantron.sub_bubblelines.n"}
9575: which are the total number of bubble, lines, the number of bubble
9576: lines for response n and number of the first bubble line for response n,

9587: =item scantron_process_students() :
9588:
9589: Routine that does the actual grading of the bubble sheet information.
9590:
9591: The parsed scanline hash is added to %env
9592:
9593: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9594: foreach resource , with the form data of
9595:

9601: 'grade_symb' => symb of resource to grade
9602:
