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 bubble sheet
4997:
4998:
4999: The overall process is that a scanned in bubble sheet data is uploaded
5000: into a course. When a user wants to grade, they select a
5001: sequence/folder of resources, a file of bubble sheet 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 bubble sheet 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 bubble sheet
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.

9659: =head1 NAME
9660:
9661: Apache::grades
9662:
9663: =head1 SYNOPSIS
9664:
9665: Handles the viewing of grades.
9666:
9667: This is part of the LearningOnline Network with CAPA project
9668: described at http://www.lon-capa.org.
9669:
9670: =head1 OVERVIEW
9671:
9672: Do an ssi with retries:
9673: While I'd love to factor out this with the vesrion in lonprintout,
9674: 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
9675: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9676:
9677: At least the logic that drives this has been pulled out into loncommon.
9678:
9679:
9680:
9681: ssi_with_retries - Does the server side include of a resource.
9682: if the ssi call returns an error we'll retry it up to
9683: the number of times requested by the caller.
9684: If we still have a proble, no text is appended to the
9685: output and we set some global variables.
9686: to indicate to the caller an SSI error occurred.
9687: All of this is supposed to deal with the issues described
9688: in LonCAPA BZ 5631 see:
9689: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9690: by informing the user that this happened.
9691:
9692: Parameters:
9693: resource - The resource to include. This is passed directly, without
9694: interpretation to lonnet::ssi.
9695: form - The form hash parameters that guide the interpretation of the resource
9696:
9697: retries - Number of retries allowed before giving up completely.
9698: Returns:
9699: On success, returns the rendered resource identified by the resource parameter.
9700: Side Effects:
9701: The following global variables can be set:
9702: ssi_error - If an unrecoverable error occurred this becomes true.
9703: It is up to the caller to initialize this to false
9704: if desired.
9705: ssi_error_resource - If an unrecoverable error occurred, this is the value
9706: of the resource that could not be rendered by the ssi
9707: call.
9708: ssi_error_message - The error string fetched from the ssi response
9709: in the event of an error.

9719:
9720: =item scantron_get_correction() :
9721:
9722: Builds the interface screen to interact with the operator to fix a
9723: specific error condition in a specific scanline
9724:
9725: Arguments:
9726: $r - Apache request object
9727: $i - number of the current scanline
9728: $scan_record - hash ref as returned from &scantron_parse_scanline()
9729: $scan_config - hash ref as returned from &get_scantron_config()
9730: $line - full contents of the current scanline
9731: $error - error condition, valid values are
9732: 'incorrectCODE', 'duplicateCODE',
9733: 'doublebubble', 'missingbubble',
9734: 'duplicateID', 'incorrectID'
9735: $arg - extra information needed
9736: For errors:
9737: - duplicateID - paper number that this studentID was seen before on
9738: - duplicateCODE - array ref of the paper numbers this CODE was
9739: seen on before
9740: - incorrectCODE - current incorrect CODE
9741: - doublebubble - array ref of the bubble lines that have double
9742: bubble errors
9743: - missingbubble - array ref of the bubble lines that have missing
9744: bubble errors
9745:
9746: =item scantron_get_maxbubble() :
9747:
9748: Arguments:
9749: $nav_error - Reference to scalar which is a flag to indicate a
9750: failure to retrieve a navmap object.
9751: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9752: calling routine should trap the error condition and display the warning
9753: found in &navmap_errormsg().
9754:
9755: Returns the maximum number of bubble lines that are expected to
9756: occur. Does this by walking the selected sequence rendering the
9757: resource and then checking &Apache::lonxml::get_problem_counter()
9758: for what the current value of the problem counter is.
9759:
9760: Caches the results to $env{'form.scantron_maxbubble'},
9761: $env{'form.scantron.bubble_lines.n'},
9762: $env{'form.scantron.first_bubble_line.n'} and
9763: $env{"form.scantron.sub_bubblelines.n"}
9764: which are the total number of bubble, lines, the number of bubble
9765: lines for response n and number of the first bubble line for response n,
9766: and a comma separated list of numbers of bubble lines for sub-questions
9767: (for optionresponse, matchresponse, and rankresponse items), for response n.
9768:
9769:
9770: =item scantron_validate_missingbubbles() :
9771:
9772: Validates all scanlines in the selected file to not have any
9773: answers that don't have bubbles that have not been verified
9774: to be bubble free.
9775:
9776: =item scantron_process_students() :
9777:
9778: Routine that does the actual grading of the bubble sheet information.
9779:
9780: The parsed scanline hash is added to %env
9781:
9782: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9783: foreach resource , with the form data of
9784:
9785: 'submitted' =>'scantron'
9786: 'grade_target' =>'grade',
9787: 'grade_username'=> username of student
9788: 'grade_domain' => domain of student
9789: 'grade_courseid'=> of course
9790: 'grade_symb' => symb of resource to grade
9791:
9792: This triggers a grading pass. The problem grading code takes care
9793: of converting the bubbled letter information (now in %env) into a
9794: valid submission.
9795:
9796: =item scantron_upload_scantron_data() :
9797:
9798: Creates the screen for adding a new bubble sheet data file to a course.
9799:
9800: =item scantron_upload_scantron_data_save() :
9801:
9802: Adds a provided bubble information data file to the course if user
9803: has the correct privileges to do so.
9804:
9805: =item valid_file() :
9806:
9807: Validates that the requested bubble data file exists in the course.
9808:
9809: =item scantron_download_scantron_data() :
9810:
9811: Shows a list of the three internal files (original, corrected,
9812: skipped) for a specific bubble sheet data file that exists in the
9813: course.
9814:
9815: =item scantron_validate_ID() :
9816:
9817: Validates all scanlines in the selected file to not have any
9818: invalid or underspecified student/employee IDs
9819:
9820: =item navmap_errormsg() :
9821:
9822: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9823: Should be called whenever the request to instantiate a navmap object fails.
