5505: =head1 Bubble sheet grading routines
5506:
5507: For this documentation:
5508:
5509: 'scanline' refers to the full line of characters
5510: from the file that we are parsing that represents one entire sheet
5511:
5512: 'bubble line' refers to the data
5513: representing the line of bubbles that are on the physical bubblesheet
5514:
5515:
5516: The overall process is that a scanned in bubblesheet data is uploaded
5517: into a course. When a user wants to grade, they select a
5518: sequence/folder of resources, a file of bubblesheet info, and pick
5519: one of the predefined configurations for what each scanline looks
5520: like.
5521:
5522: Next each scanline is checked for any errors of either 'missing
5523: bubbles' (it's an error because it may have been mis-scanned
5524: because too light bubbling), 'double bubble' (each bubble line should
5525: have no more than one letter picked), invalid or duplicated CODE,
5526: invalid student/employee ID
5527:
5528: If the CODE option is used that determines the randomization of the
5529: homework problems, either way the student/employee ID is looked up into a
5530: username:domain.
5531:
5532: During the validation phase the instructor can choose to skip scanlines.
5533:
5534: After the validation phase, there are now 3 bubblesheet files
5535:
5536: scantron_original_filename (unmodified original file)
5537: scantron_corrected_filename (file where the corrected information has replaced the original information)
5538: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5539:
5540: Also there is a separate hash nohist_scantrondata that contains extra
5541: correction information that isn't representable in the bubblesheet
5542: file (see &scantron_getfile() for more information)
5543:
5544: After all scanlines are either valid, marked as valid or skipped, then
5545: foreach line foreach problem in the picked sequence, an ssi request is
5546: made that simulates a user submitting their selected letter(s) against
5547: the homework problem.

10820: =head1 NAME
10821:
10822: Apache::grades
10823:
10824: =head1 SYNOPSIS
10825:
10826: Handles the viewing of grades.
10827:
10828: This is part of the LearningOnline Network with CAPA project
10829: described at http://www.lon-capa.org.
10830:
10831: =head1 OVERVIEW
10832:
10833: Do an ssi with retries:
10834: While I'd love to factor out this with the vesrion in lonprintout,
10835: 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
10836: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10837:
10838: At least the logic that drives this has been pulled out into loncommon.
10839:
10840:
10841:
10842: ssi_with_retries - Does the server side include of a resource.
10843: if the ssi call returns an error we'll retry it up to
10844: the number of times requested by the caller.
10845: If we still have a problem, no text is appended to the
10846: output and we set some global variables.
10847: to indicate to the caller an SSI error occurred.
10848: All of this is supposed to deal with the issues described
10849: in LON-CAPA BZ 5631 see:
10850: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10851: by informing the user that this happened.
10852:
10853: Parameters:
10854: resource - The resource to include. This is passed directly, without
10855: interpretation to lonnet::ssi.
10856: form - The form hash parameters that guide the interpretation of the resource
10857:
10858: retries - Number of retries allowed before giving up completely.
10859: Returns:
10860: On success, returns the rendered resource identified by the resource parameter.
10861: Side Effects:
10862: The following global variables can be set:
10863: ssi_error - If an unrecoverable error occurred this becomes true.
10864: It is up to the caller to initialize this to false
10865: if desired.
10866: ssi_error_resource - If an unrecoverable error occurred, this is the value
10867: of the resource that could not be rendered by the ssi
10868: call.
10869: ssi_error_message - The error string fetched from the ssi response
10870: in the event of an error.

10880:
10881: =item scantron_get_correction() :
10882:
10883: Builds the interface screen to interact with the operator to fix a
10884: specific error condition in a specific scanline
10885:
10886: Arguments:
10887: $r - Apache request object
10888: $i - number of the current scanline
10889: $scan_record - hash ref as returned from &scantron_parse_scanline()
10890: $scan_config - hash ref as returned from &Apache::lonnet::get_scantron_config()
10891: $line - full contents of the current scanline
10892: $error - error condition, valid values are
10893: 'incorrectCODE', 'duplicateCODE',
10894: 'doublebubble', 'missingbubble',
10895: 'duplicateID', 'incorrectID'
10896: $arg - extra information needed
10897: For errors:
10898: - duplicateID - paper number that this studentID was seen before on
10899: - duplicateCODE - array ref of the paper numbers this CODE was
10900: seen on before
10901: - incorrectCODE - current incorrect CODE
10902: - doublebubble - array ref of the bubble lines that have double
10903: bubble errors
10904: - missingbubble - array ref of the bubble lines that have missing
10905: bubble errors
10906:
10907: $randomorder - True if exam folder has randomorder set
10908: $randompick - True if exam folder has randompick set
10909: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
10910: for current line to question number used for same question
10911: in "Master Seqence" (as seen by Course Coordinator).
10912: $startline - Reference to hash where key is question number (0 is first)
10913: and value is number of first bubble line for current student
10914: or code-based randompick and/or randomorder.
10915:
10916:
10917: =item scantron_get_maxbubble() :
10918:
10919: Arguments:
10920: $nav_error - Reference to scalar which is a flag to indicate a
10921: failure to retrieve a navmap object.
10922: if $nav_error is set to 1 by scantron_get_maxbubble(), the
10923: calling routine should trap the error condition and display the warning
10924: found in &navmap_errormsg().
10925:
10926: $scantron_config - Reference to bubblesheet format configuration hash.
10927:
10928: Returns the maximum number of bubble lines that are expected to
10929: occur. Does this by walking the selected sequence rendering the
10930: resource and then checking &Apache::lonxml::get_problem_counter()
10931: for what the current value of the problem counter is.
10932:
10933: Caches the results to $env{'form.scantron_maxbubble'},
10934: $env{'form.scantron.bubble_lines.n'},
10935: $env{'form.scantron.first_bubble_line.n'} and
10936: $env{"form.scantron.sub_bubblelines.n"}
10937: which are the total number of bubble lines, the number of bubble
10938: lines for response n and number of the first bubble line for response n,
10939: and a comma separated list of numbers of bubble lines for sub-questions
10940: (for optionresponse, matchresponse, and rankresponse items), for response n.
10941:
10942:
10943: =item scantron_validate_missingbubbles() :
10944:
10945: Validates all scanlines in the selected file to not have any
10946: answers that don't have bubbles that have not been verified
10947: to be bubble free.
10948:
10949: =item scantron_process_students() :
10950:
10951: Routine that does the actual grading of the bubblesheet information.
10952:
10953: The parsed scanline hash is added to %env
10954:
10955: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
10956: foreach resource , with the form data of
10957:
10958: 'submitted' =>'scantron'
10959: 'grade_target' =>'grade',
10960: 'grade_username'=> username of student
10961: 'grade_domain' => domain of student
10962: 'grade_courseid'=> of course
10963: 'grade_symb' => symb of resource to grade
10964:
10965: This triggers a grading pass. The problem grading code takes care
10966: of converting the bubbled letter information (now in %env) into a
10967: valid submission.
10968:
10969: =item scantron_upload_scantron_data() :
10970:

10983:
10984: Shows a list of the three internal files (original, corrected,
10985: skipped) for a specific bubblesheet data file that exists in the
10986: course.
10987:
10988: =item scantron_validate_ID() :
10989:
10990: Validates all scanlines in the selected file to not have any
10991: invalid or underspecified student/employee IDs
10992:
10993: =item navmap_errormsg() :
10994:
10995: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
