4993: =head1 Bubble sheet grading routines
4994:
4995: For this documentation:
4996:
4997: 'scanline' refers to the full line of characters
4998: from the file that we are parsing that represents one entire sheet
4999:
5000: 'bubble line' refers to the data
5001: representing the line of bubbles that are on the physical bubblesheet
5002:
5003:
5004: The overall process is that a scanned in bubblesheet data is uploaded
5005: into a course. When a user wants to grade, they select a
5006: sequence/folder of resources, a file of bubblesheet info, and pick
5007: one of the predefined configurations for what each scanline looks
5008: like.
5009:
5010: Next each scanline is checked for any errors of either 'missing
5011: bubbles' (it's an error because it may have been mis-scanned
5012: because too light bubbling), 'double bubble' (each bubble line should
5013: have no more that one letter picked), invalid or duplicated CODE,
5014: invalid student/employee ID
5015:
5016: If the CODE option is used that determines the randomization of the
5017: homework problems, either way the student/employee ID is looked up into a
5018: username:domain.
5019:
5020: During the validation phase the instructor can choose to skip scanlines.
5021:
5022: After the validation phase, there are now 3 bubblesheet files
5023:
5024: scantron_original_filename (unmodified original file)
5025: scantron_corrected_filename (file where the corrected information has replaced the original information)
5026: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5027:
5028: Also there is a separate hash nohist_scantrondata that contains extra
5029: correction information that isn't representable in the bubblesheet
5030: file (see &scantron_getfile() for more information)
5031:
5032: After all scanlines are either valid, marked as valid or skipped, then
5033: foreach line foreach problem in the picked sequence, an ssi request is
5034: made that simulates a user submitting their selected letter(s) against
5035: the homework problem.

9693: =head1 NAME
9694:
9695: Apache::grades
9696:
9697: =head1 SYNOPSIS
9698:
9699: Handles the viewing of grades.
9700:
9701: This is part of the LearningOnline Network with CAPA project
9702: described at http://www.lon-capa.org.
9703:
9704: =head1 OVERVIEW
9705:
9706: Do an ssi with retries:
9707: While I'd love to factor out this with the vesrion in lonprintout,
9708: 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
9709: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9710:
9711: At least the logic that drives this has been pulled out into loncommon.
9712:
9713:
9714:
9715: ssi_with_retries - Does the server side include of a resource.
9716: if the ssi call returns an error we'll retry it up to
9717: the number of times requested by the caller.
9718: If we still have a proble, no text is appended to the
9719: output and we set some global variables.
9720: to indicate to the caller an SSI error occurred.
9721: All of this is supposed to deal with the issues described
9722: in LonCAPA BZ 5631 see:
9723: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9724: by informing the user that this happened.
9725:
9726: Parameters:
9727: resource - The resource to include. This is passed directly, without
9728: interpretation to lonnet::ssi.
9729: form - The form hash parameters that guide the interpretation of the resource
9730:
9731: retries - Number of retries allowed before giving up completely.
9732: Returns:
9733: On success, returns the rendered resource identified by the resource parameter.
9734: Side Effects:
9735: The following global variables can be set:
9736: ssi_error - If an unrecoverable error occurred this becomes true.
9737: It is up to the caller to initialize this to false
9738: if desired.
9739: ssi_error_resource - If an unrecoverable error occurred, this is the value
9740: of the resource that could not be rendered by the ssi
9741: call.
9742: ssi_error_message - The error string fetched from the ssi response
9743: in the event of an error.

9753:
9754: =item scantron_get_correction() :
9755:
9756: Builds the interface screen to interact with the operator to fix a
9757: specific error condition in a specific scanline
9758:
9759: Arguments:
9760: $r - Apache request object
9761: $i - number of the current scanline
9762: $scan_record - hash ref as returned from &scantron_parse_scanline()
9763: $scan_config - hash ref as returned from &get_scantron_config()
9764: $line - full contents of the current scanline
9765: $error - error condition, valid values are
9766: 'incorrectCODE', 'duplicateCODE',
9767: 'doublebubble', 'missingbubble',
9768: 'duplicateID', 'incorrectID'
9769: $arg - extra information needed
9770: For errors:
9771: - duplicateID - paper number that this studentID was seen before on
9772: - duplicateCODE - array ref of the paper numbers this CODE was
9773: seen on before
9774: - incorrectCODE - current incorrect CODE
9775: - doublebubble - array ref of the bubble lines that have double
9776: bubble errors
9777: - missingbubble - array ref of the bubble lines that have missing
9778: bubble errors
9779:
9780: =item scantron_get_maxbubble() :
9781:
9782: Arguments:
9783: $nav_error - Reference to scalar which is a flag to indicate a
9784: failure to retrieve a navmap object.
9785: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9786: calling routine should trap the error condition and display the warning
9787: found in &navmap_errormsg().
9788:
9789: Returns the maximum number of bubble lines that are expected to
9790: occur. Does this by walking the selected sequence rendering the
9791: resource and then checking &Apache::lonxml::get_problem_counter()
9792: for what the current value of the problem counter is.
9793:
9794: Caches the results to $env{'form.scantron_maxbubble'},
9795: $env{'form.scantron.bubble_lines.n'},
9796: $env{'form.scantron.first_bubble_line.n'} and
9797: $env{"form.scantron.sub_bubblelines.n"}
9798: which are the total number of bubble, lines, the number of bubble
9799: lines for response n and number of the first bubble line for response n,
9800: and a comma separated list of numbers of bubble lines for sub-questions
9801: (for optionresponse, matchresponse, and rankresponse items), for response n.
9802:
9803:
9804: =item scantron_validate_missingbubbles() :
9805:
9806: Validates all scanlines in the selected file to not have any
9807: answers that don't have bubbles that have not been verified
9808: to be bubble free.
9809:
9810: =item scantron_process_students() :
9811:
9812: Routine that does the actual grading of the bubblesheet information.
9813:
9814: The parsed scanline hash is added to %env
9815:
9816: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9817: foreach resource , with the form data of
9818:
9819: 'submitted' =>'scantron'
9820: 'grade_target' =>'grade',
9821: 'grade_username'=> username of student
9822: 'grade_domain' => domain of student
9823: 'grade_courseid'=> of course
9824: 'grade_symb' => symb of resource to grade
9825:
9826: This triggers a grading pass. The problem grading code takes care
9827: of converting the bubbled letter information (now in %env) into a
9828: valid submission.
9829:
9830: =item scantron_upload_scantron_data() :
9831:
9832: Creates the screen for adding a new bubblesheet data file to a course.
9833:
9834: =item scantron_upload_scantron_data_save() :
9835:
9836: Adds a provided bubble information data file to the course if user
9837: has the correct privileges to do so.
9838:
9839: =item valid_file() :
9840:
9841: Validates that the requested bubble data file exists in the course.
9842:
9843: =item scantron_download_scantron_data() :
9844:
9845: Shows a list of the three internal files (original, corrected,
9846: skipped) for a specific bubblesheet data file that exists in the
9847: course.
9848:
9849: =item scantron_validate_ID() :
9850:
9851: Validates all scanlines in the selected file to not have any
9852: invalid or underspecified student/employee IDs
9853:
9854: =item navmap_errormsg() :
9855:
9856: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9857: Should be called whenever the request to instantiate a navmap object fails.
