4805: =head1 Bubble sheet grading routines
4806:
4807: For this documentation:
4808:
4809: 'scanline' refers to the full line of characters
4810: from the file that we are parsing that represents one entire sheet
4811:
4812: 'bubble line' refers to the data
4813: representing the line of bubbles that are on the physical bubble sheet
4814:
4815:
4816: The overall process is that a scanned in bubble sheet data is uploaded
4817: into a course. When a user wants to grade, they select a
4818: sequence/folder of resources, a file of bubble sheet info, and pick
4819: one of the predefined configurations for what each scanline looks
4820: like.
4821:
4822: Next each scanline is checked for any errors of either 'missing
4823: bubbles' (it's an error because it may have been mis-scanned
4824: because too light bubbling), 'double bubble' (each bubble line should
4825: have no more that one letter picked), invalid or duplicated CODE,
4826: invalid student/employee ID
4827:
4828: If the CODE option is used that determines the randomization of the
4829: homework problems, either way the student/employee ID is looked up into a
4830: username:domain.
4831:
4832: During the validation phase the instructor can choose to skip scanlines.
4833:
4834: After the validation phase, there are now 3 bubble sheet files
4835:
4836: scantron_original_filename (unmodified original file)
4837: scantron_corrected_filename (file where the corrected information has replaced the original information)
4838: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4839:
4840: Also there is a separate hash nohist_scantrondata that contains extra
4841: correction information that isn't representable in the bubble sheet
4842: file (see &scantron_getfile() for more information)
4843:
4844: After all scanlines are either valid, marked as valid or skipped, then
4845: foreach line foreach problem in the picked sequence, an ssi request is
4846: made that simulates a user submitting their selected letter(s) against
4847: the homework problem.

9486: =head1 NAME
9487:
9488: Apache::grades
9489:
9490: =head1 SYNOPSIS
9491:
9492: Handles the viewing of grades.
9493:
9494: This is part of the LearningOnline Network with CAPA project
9495: described at http://www.lon-capa.org.
9496:
9497: =head1 OVERVIEW
9498:
9499: Do an ssi with retries:
9500: While I'd love to factor out this with the vesrion in lonprintout,
9501: 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
9502: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9503:
9504: At least the logic that drives this has been pulled out into loncommon.
9505:
9506:
9507:
9508: ssi_with_retries - Does the server side include of a resource.
9509: if the ssi call returns an error we'll retry it up to
9510: the number of times requested by the caller.
9511: If we still have a proble, no text is appended to the
9512: output and we set some global variables.
9513: to indicate to the caller an SSI error occurred.
9514: All of this is supposed to deal with the issues described
9515: in LonCAPA BZ 5631 see:
9516: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9517: by informing the user that this happened.
9518:
9519: Parameters:
9520: resource - The resource to include. This is passed directly, without
9521: interpretation to lonnet::ssi.
9522: form - The form hash parameters that guide the interpretation of the resource
9523:
9524: retries - Number of retries allowed before giving up completely.
9525: Returns:
9526: On success, returns the rendered resource identified by the resource parameter.
9527: Side Effects:
9528: The following global variables can be set:
9529: ssi_error - If an unrecoverable error occurred this becomes true.
9530: It is up to the caller to initialize this to false
9531: if desired.
9532: ssi_error_resource - If an unrecoverable error occurred, this is the value
9533: of the resource that could not be rendered by the ssi

9548:
9549: Builds the interface screen to interact with the operator to fix a
9550: specific error condition in a specific scanline
9551:
9552: Arguments:
9553: $r - Apache request object
9554: $i - number of the current scanline
9555: $scan_record - hash ref as returned from &scantron_parse_scanline()
9556: $scan_config - hash ref as returned from &get_scantron_config()
9557: $line - full contents of the current scanline
9558: $error - error condition, valid values are
9559: 'incorrectCODE', 'duplicateCODE',
9560: 'doublebubble', 'missingbubble',
9561: 'duplicateID', 'incorrectID'
9562: $arg - extra information needed
9563: For errors:
9564: - duplicateID - paper number that this studentID was seen before on
9565: - duplicateCODE - array ref of the paper numbers this CODE was
9566: seen on before
9567: - incorrectCODE - current incorrect CODE
9568: - doublebubble - array ref of the bubble lines that have double
9569: bubble errors

9571: bubble errors

9573: =item scantron_get_maxbubble() :
9574:
9575: Arguments:
9576: $nav_error - Reference to scalar which is a flag to indicate a
9577: failure to retrieve a navmap object.
9578: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9579: calling routine should trap the error condition and display the warning
9580: found in &navmap_errormsg().
9581:
9582: $scantron_config - Reference to bubblesheet format configuration hash.
9583:
9584: Returns the maximum number of bubble lines that are expected to
9585: occur. Does this by walking the selected sequence rendering the
9586: resource and then checking &Apache::lonxml::get_problem_counter()
9587: for what the current value of the problem counter is.
9588:
9589: Caches the results to $env{'form.scantron_maxbubble'},
9590: $env{'form.scantron.bubble_lines.n'},
9591: $env{'form.scantron.first_bubble_line.n'} and
9592: $env{"form.scantron.sub_bubblelines.n"}
9593: which are the total number of bubble, lines, the number of bubble
9594: lines for response n and number of the first bubble line for response n,
9595: and a comma separated list of numbers of bubble lines for sub-questions
9596: (for optionresponse, matchresponse, and rankresponse items), for response n.

9607: Routine that does the actual grading of the bubble sheet information.
9608:
9609: The parsed scanline hash is added to %env
9610:
9611: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9612: foreach resource , with the form data of
9613:
9614: 'submitted' =>'scantron'
9615: 'grade_target' =>'grade',
9616: 'grade_username'=> username of student
9617: 'grade_domain' => domain of student
9618: 'grade_courseid'=> of course
9619: 'grade_symb' => symb of resource to grade
9620:
9621: This triggers a grading pass. The problem grading code takes care
