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.

10849: =head1 NAME
10850:
10851: Apache::grades
10852:
10853: =head1 SYNOPSIS
10854:
10855: Handles the viewing of grades.
10856:
10857: This is part of the LearningOnline Network with CAPA project
10858: described at http://www.lon-capa.org.
10859:
10860: =head1 OVERVIEW
10861:
10862: Do an ssi with retries:
10863: While I'd love to factor out this with the vesrion in lonprintout,
10864: 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
10865: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10866:
10867: At least the logic that drives this has been pulled out into loncommon.
10868:
10869:
10870:
10871: ssi_with_retries - Does the server side include of a resource.
10872: if the ssi call returns an error we'll retry it up to
10873: the number of times requested by the caller.
10874: If we still have a problem, no text is appended to the
10875: output and we set some global variables.
10876: to indicate to the caller an SSI error occurred.
10877: All of this is supposed to deal with the issues described
10878: in LON-CAPA BZ 5631 see:
10879: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10880: by informing the user that this happened.
10881:
10882: Parameters:
10883: resource - The resource to include. This is passed directly, without
10884: interpretation to lonnet::ssi.
10885: form - The form hash parameters that guide the interpretation of the resource
10886:
10887: retries - Number of retries allowed before giving up completely.
10888: Returns:
10889: On success, returns the rendered resource identified by the resource parameter.
10890: Side Effects:
10891: The following global variables can be set:
10892: ssi_error - If an unrecoverable error occurred this becomes true.
10893: It is up to the caller to initialize this to false
10894: if desired.
10895: ssi_error_resource - If an unrecoverable error occurred, this is the value
10896: of the resource that could not be rendered by the ssi
10897: call.
10898: ssi_error_message - The error string fetched from the ssi response
10899: in the event of an error.

10909:
10910: =item scantron_get_correction() :
10911:
10912: Builds the interface screen to interact with the operator to fix a
10913: specific error condition in a specific scanline
10914:
10915: Arguments:
10916: $r - Apache request object
10917: $i - number of the current scanline
10918: $scan_record - hash ref as returned from &scantron_parse_scanline()
10919: $scan_config - hash ref as returned from &get_scantron_config()
10920: $line - full contents of the current scanline
10921: $error - error condition, valid values are
10922: 'incorrectCODE', 'duplicateCODE',
10923: 'doublebubble', 'missingbubble',
10924: 'duplicateID', 'incorrectID'
10925: $arg - extra information needed
10926: For errors:
10927: - duplicateID - paper number that this studentID was seen before on
10928: - duplicateCODE - array ref of the paper numbers this CODE was
10929: seen on before
10930: - incorrectCODE - current incorrect CODE
10931: - doublebubble - array ref of the bubble lines that have double
10932: bubble errors
10933: - missingbubble - array ref of the bubble lines that have missing
10934: bubble errors
10935:
10936: $randomorder - True if exam folder has randomorder set
10937: $randompick - True if exam folder has randompick set
10938: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
10939: for current line to question number used for same question
10940: in "Master Seqence" (as seen by Course Coordinator).
10941: $startline - Reference to hash where key is question number (0 is first)
10942: and value is number of first bubble line for current student
10943: or code-based randompick and/or randomorder.
10944:
10945:
10946: =item scantron_get_maxbubble() :
10947:
10948: Arguments:
10949: $nav_error - Reference to scalar which is a flag to indicate a
10950: failure to retrieve a navmap object.
10951: if $nav_error is set to 1 by scantron_get_maxbubble(), the
10952: calling routine should trap the error condition and display the warning
10953: found in &navmap_errormsg().
10954:
10955: $scantron_config - Reference to bubblesheet format configuration hash.
10956:
10957: Returns the maximum number of bubble lines that are expected to
10958: occur. Does this by walking the selected sequence rendering the
10959: resource and then checking &Apache::lonxml::get_problem_counter()
10960: for what the current value of the problem counter is.
10961:
10962: Caches the results to $env{'form.scantron_maxbubble'},
10963: $env{'form.scantron.bubble_lines.n'},
10964: $env{'form.scantron.first_bubble_line.n'} and
10965: $env{"form.scantron.sub_bubblelines.n"}
10966: which are the total number of bubble lines, the number of bubble
10967: lines for response n and number of the first bubble line for response n,
10968: and a comma separated list of numbers of bubble lines for sub-questions
10969: (for optionresponse, matchresponse, and rankresponse items), for response n.
10970:
10971:
10972: =item scantron_validate_missingbubbles() :
10973:
10974: Validates all scanlines in the selected file to not have any
10975: answers that don't have bubbles that have not been verified
10976: to be bubble free.
10977:
10978: =item scantron_process_students() :
10979:
10980: Routine that does the actual grading of the bubblesheet information.
10981:
10982: The parsed scanline hash is added to %env
10983:
10984: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
10985: foreach resource , with the form data of
10986:
10987: 'submitted' =>'scantron'
10988: 'grade_target' =>'grade',
10989: 'grade_username'=> username of student
10990: 'grade_domain' => domain of student
10991: 'grade_courseid'=> of course
10992: 'grade_symb' => symb of resource to grade
10993:
10994: This triggers a grading pass. The problem grading code takes care
10995: of converting the bubbled letter information (now in %env) into a
10996: valid submission.
10997:
10998: =item scantron_upload_scantron_data() :
10999:

11014: skipped) for a specific bubblesheet data file that exists in the
11015: course.
11016:
11017: =item scantron_validate_ID() :
11018:
11019: Validates all scanlines in the selected file to not have any
11020: invalid or underspecified student/employee IDs
