4988: =head1 Bubble sheet grading routines
4989:
4990: For this documentation:
4991:
4992: 'scanline' refers to the full line of characters
4993: from the file that we are parsing that represents one entire sheet
4994:
4995: 'bubble line' refers to the data
4996: representing the line of bubbles that are on the physical bubblesheet
4997:
4998:
4999: The overall process is that a scanned in bubblesheet data is uploaded
5000: into a course. When a user wants to grade, they select a
5001: sequence/folder of resources, a file of bubblesheet info, and pick
5002: one of the predefined configurations for what each scanline looks
5003: like.
5004:
5005: Next each scanline is checked for any errors of either 'missing
5006: bubbles' (it's an error because it may have been mis-scanned
5007: because too light bubbling), 'double bubble' (each bubble line should
5008: have no more that one letter picked), invalid or duplicated CODE,
5009: invalid student/employee ID
5010:
5011: If the CODE option is used that determines the randomization of the
5012: homework problems, either way the student/employee ID is looked up into a
5013: username:domain.
5014:
5015: During the validation phase the instructor can choose to skip scanlines.
5016:
5017: After the validation phase, there are now 3 bubblesheet files
5018:
5019: scantron_original_filename (unmodified original file)
5020: scantron_corrected_filename (file where the corrected information has replaced the original information)
5021: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5022:
5023: Also there is a separate hash nohist_scantrondata that contains extra
5024: correction information that isn't representable in the bubblesheet
5025: file (see &scantron_getfile() for more information)
5026:
5027: After all scanlines are either valid, marked as valid or skipped, then
5028: foreach line foreach problem in the picked sequence, an ssi request is
5029: made that simulates a user submitting their selected letter(s) against
5030: the homework problem.

9670: =head1 NAME
9671:
9672: Apache::grades
9673:
9674: =head1 SYNOPSIS
9675:
9676: Handles the viewing of grades.
9677:
9678: This is part of the LearningOnline Network with CAPA project
9679: described at http://www.lon-capa.org.
9680:
9681: =head1 OVERVIEW
9682:
9683: Do an ssi with retries:
9684: While I'd love to factor out this with the vesrion in lonprintout,
9685: 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
9686: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9687:
9688: At least the logic that drives this has been pulled out into loncommon.
9689:
9690:
9691:
9692: ssi_with_retries - Does the server side include of a resource.
9693: if the ssi call returns an error we'll retry it up to
9694: the number of times requested by the caller.
9695: If we still have a proble, no text is appended to the
9696: output and we set some global variables.
9697: to indicate to the caller an SSI error occurred.
9698: All of this is supposed to deal with the issues described
9699: in LonCAPA BZ 5631 see:
9700: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9701: by informing the user that this happened.
9702:
9703: Parameters:
9704: resource - The resource to include. This is passed directly, without
9705: interpretation to lonnet::ssi.
9706: form - The form hash parameters that guide the interpretation of the resource
9707:
9708: retries - Number of retries allowed before giving up completely.
9709: Returns:
9710: On success, returns the rendered resource identified by the resource parameter.
9711: Side Effects:
9712: The following global variables can be set:
9713: ssi_error - If an unrecoverable error occurred this becomes true.
9714: It is up to the caller to initialize this to false
9715: if desired.
9716: ssi_error_resource - If an unrecoverable error occurred, this is the value
9717: of the resource that could not be rendered by the ssi
9718: call.
9719: ssi_error_message - The error string fetched from the ssi response
9720: in the event of an error.

9730:
9731: =item scantron_get_correction() :
9732:
9733: Builds the interface screen to interact with the operator to fix a
9734: specific error condition in a specific scanline
9735:
9736: Arguments:
9737: $r - Apache request object
9738: $i - number of the current scanline
9739: $scan_record - hash ref as returned from &scantron_parse_scanline()
9740: $scan_config - hash ref as returned from &get_scantron_config()
9741: $line - full contents of the current scanline
9742: $error - error condition, valid values are
9743: 'incorrectCODE', 'duplicateCODE',
9744: 'doublebubble', 'missingbubble',
9745: 'duplicateID', 'incorrectID'
9746: $arg - extra information needed
9747: For errors:
9748: - duplicateID - paper number that this studentID was seen before on
9749: - duplicateCODE - array ref of the paper numbers this CODE was
9750: seen on before
9751: - incorrectCODE - current incorrect CODE
9752: - doublebubble - array ref of the bubble lines that have double
9753: bubble errors
9754: - missingbubble - array ref of the bubble lines that have missing
9755: bubble errors
9756:
9757: =item scantron_get_maxbubble() :
9758:
9759: Arguments:
9760: $nav_error - Reference to scalar which is a flag to indicate a
9761: failure to retrieve a navmap object.
9762: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9763: calling routine should trap the error condition and display the warning
9764: found in &navmap_errormsg().
9765:
9766: Returns the maximum number of bubble lines that are expected to
9767: occur. Does this by walking the selected sequence rendering the
9768: resource and then checking &Apache::lonxml::get_problem_counter()
9769: for what the current value of the problem counter is.
9770:
9771: Caches the results to $env{'form.scantron_maxbubble'},
9772: $env{'form.scantron.bubble_lines.n'},
9773: $env{'form.scantron.first_bubble_line.n'} and
9774: $env{"form.scantron.sub_bubblelines.n"}
9775: which are the total number of bubble, lines, the number of bubble
9776: lines for response n and number of the first bubble line for response n,
9777: and a comma separated list of numbers of bubble lines for sub-questions
9778: (for optionresponse, matchresponse, and rankresponse items), for response n.
9779:
9780:
9781: =item scantron_validate_missingbubbles() :
9782:
9783: Validates all scanlines in the selected file to not have any
9784: answers that don't have bubbles that have not been verified
9785: to be bubble free.
9786:
9787: =item scantron_process_students() :
9788:
9789: Routine that does the actual grading of the bubblesheet information.
9790:
9791: The parsed scanline hash is added to %env
9792:
9793: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9794: foreach resource , with the form data of
9795:
9796: 'submitted' =>'scantron'
9797: 'grade_target' =>'grade',
9798: 'grade_username'=> username of student
9799: 'grade_domain' => domain of student
9800: 'grade_courseid'=> of course
9801: 'grade_symb' => symb of resource to grade
9802:
9803: This triggers a grading pass. The problem grading code takes care
9804: of converting the bubbled letter information (now in %env) into a
9805: valid submission.
9806:
9807: =item scantron_upload_scantron_data() :
9808:
9809: Creates the screen for adding a new bubblesheet data file to a course.
9810:
9811: =item scantron_upload_scantron_data_save() :
9812:
9813: Adds a provided bubble information data file to the course if user
9814: has the correct privileges to do so.
9815:
9816: =item valid_file() :
9817:
9818: Validates that the requested bubble data file exists in the course.
9819:
9820: =item scantron_download_scantron_data() :
9821:
9822: Shows a list of the three internal files (original, corrected,
9823: skipped) for a specific bubblesheet data file that exists in the
9824: course.
9825:
9826: =item scantron_validate_ID() :
9827:
9828: Validates all scanlines in the selected file to not have any
9829: invalid or underspecified student/employee IDs
9830:
9831: =item navmap_errormsg() :
9832:
9833: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9834: Should be called whenever the request to instantiate a navmap object fails.
