4997: =head1 Bubble sheet grading routines
4998:
4999: For this documentation:
5000:
5001: 'scanline' refers to the full line of characters
5002: from the file that we are parsing that represents one entire sheet
5003:
5004: 'bubble line' refers to the data
5005: representing the line of bubbles that are on the physical bubblesheet
5006:
5007:
5008: The overall process is that a scanned in bubblesheet data is uploaded
5009: into a course. When a user wants to grade, they select a
5010: sequence/folder of resources, a file of bubblesheet info, and pick
5011: one of the predefined configurations for what each scanline looks
5012: like.
5013:
5014: Next each scanline is checked for any errors of either 'missing
5015: bubbles' (it's an error because it may have been mis-scanned
5016: because too light bubbling), 'double bubble' (each bubble line should
5017: have no more that one letter picked), invalid or duplicated CODE,
5018: invalid student/employee ID
5019:
5020: If the CODE option is used that determines the randomization of the
5021: homework problems, either way the student/employee ID is looked up into a
5022: username:domain.
5023:
5024: During the validation phase the instructor can choose to skip scanlines.
5025:
5026: After the validation phase, there are now 3 bubblesheet files
5027:
5028: scantron_original_filename (unmodified original file)
5029: scantron_corrected_filename (file where the corrected information has replaced the original information)
5030: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5031:
5032: Also there is a separate hash nohist_scantrondata that contains extra
5033: correction information that isn't representable in the bubblesheet
5034: file (see &scantron_getfile() for more information)
5035:
5036: After all scanlines are either valid, marked as valid or skipped, then
5037: foreach line foreach problem in the picked sequence, an ssi request is
5038: made that simulates a user submitting their selected letter(s) against
5039: the homework problem.

9802: =head1 NAME
9803:
9804: Apache::grades
9805:
9806: =head1 SYNOPSIS
9807:
9808: Handles the viewing of grades.
9809:
9810: This is part of the LearningOnline Network with CAPA project
9811: described at http://www.lon-capa.org.
9812:
9813: =head1 OVERVIEW
9814:
9815: Do an ssi with retries:
9816: While I'd love to factor out this with the vesrion in lonprintout,
9817: 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
9818: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9819:
9820: At least the logic that drives this has been pulled out into loncommon.
9821:
9822:
9823:
9824: ssi_with_retries - Does the server side include of a resource.
9825: if the ssi call returns an error we'll retry it up to
9826: the number of times requested by the caller.
9827: If we still have a proble, no text is appended to the
9828: output and we set some global variables.
9829: to indicate to the caller an SSI error occurred.
9830: All of this is supposed to deal with the issues described
9831: in LonCAPA BZ 5631 see:
9832: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9833: by informing the user that this happened.
9834:
9835: Parameters:
9836: resource - The resource to include. This is passed directly, without
9837: interpretation to lonnet::ssi.
9838: form - The form hash parameters that guide the interpretation of the resource
9839:
9840: retries - Number of retries allowed before giving up completely.
9841: Returns:
9842: On success, returns the rendered resource identified by the resource parameter.
9843: Side Effects:
9844: The following global variables can be set:
9845: ssi_error - If an unrecoverable error occurred this becomes true.
9846: It is up to the caller to initialize this to false
9847: if desired.
9848: ssi_error_resource - If an unrecoverable error occurred, this is the value
9849: of the resource that could not be rendered by the ssi
9850: call.
9851: ssi_error_message - The error string fetched from the ssi response
9852: in the event of an error.

9863: =item scantron_get_correction() :
9864:
9865: Builds the interface screen to interact with the operator to fix a
9866: specific error condition in a specific scanline
9867:
9868: Arguments:
9869: $r - Apache request object
9870: $i - number of the current scanline
9871: $scan_record - hash ref as returned from &scantron_parse_scanline()
9872: $scan_config - hash ref as returned from &get_scantron_config()
9873: $line - full contents of the current scanline
9874: $error - error condition, valid values are
9875: 'incorrectCODE', 'duplicateCODE',
9876: 'doublebubble', 'missingbubble',
9877: 'duplicateID', 'incorrectID'
9878: $arg - extra information needed
9879: For errors:
9880: - duplicateID - paper number that this studentID was seen before on
9881: - duplicateCODE - array ref of the paper numbers this CODE was
9882: seen on before
9883: - incorrectCODE - current incorrect CODE
9884: - doublebubble - array ref of the bubble lines that have double
9885: bubble errors
9886: - missingbubble - array ref of the bubble lines that have missing
9887: bubble errors
9888:
9889: =item scantron_get_maxbubble() :
9890:
9891: Arguments:
9892: $nav_error - Reference to scalar which is a flag to indicate a
9893: failure to retrieve a navmap object.
9894: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9895: calling routine should trap the error condition and display the warning
9896: found in &navmap_errormsg().
9897:
9898: $scantron_config - Reference to bubblesheet format configuration hash.
9899:
9900: Returns the maximum number of bubble lines that are expected to
9901: occur. Does this by walking the selected sequence rendering the
9902: resource and then checking &Apache::lonxml::get_problem_counter()
9903: for what the current value of the problem counter is.
9904:
9905: Caches the results to $env{'form.scantron_maxbubble'},
9906: $env{'form.scantron.bubble_lines.n'},
9907: $env{'form.scantron.first_bubble_line.n'} and
9908: $env{"form.scantron.sub_bubblelines.n"}
9909: which are the total number of bubble, lines, the number of bubble
9910: lines for response n and number of the first bubble line for response n,
9911: and a comma separated list of numbers of bubble lines for sub-questions
9912: (for optionresponse, matchresponse, and rankresponse items), for response n.
9913:
9914:
9915: =item scantron_validate_missingbubbles() :
9916:
9917: Validates all scanlines in the selected file to not have any
9918: answers that don't have bubbles that have not been verified
9919: to be bubble free.
9920:
9921: =item scantron_process_students() :
9922:
9923: Routine that does the actual grading of the bubblesheet information.
9924:
9925: The parsed scanline hash is added to %env
9926:
9927: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9928: foreach resource , with the form data of
9929:
9930: 'submitted' =>'scantron'
9931: 'grade_target' =>'grade',
9932: 'grade_username'=> username of student
9933: 'grade_domain' => domain of student
9934: 'grade_courseid'=> of course
9935: 'grade_symb' => symb of resource to grade
9936:
9937: This triggers a grading pass. The problem grading code takes care
9938: of converting the bubbled letter information (now in %env) into a
9939: valid submission.
9940:
9941: =item scantron_upload_scantron_data() :

9955:
9956: Shows a list of the three internal files (original, corrected,
9957: skipped) for a specific bubblesheet data file that exists in the
9958: course.
9959:
9960: =item scantron_validate_ID() :
9961:
9962: Validates all scanlines in the selected file to not have any
9963: invalid or underspecified student/employee IDs
