5507: =head1 Bubble sheet grading routines
5508:
5509: For this documentation:
5510:
5511: 'scanline' refers to the full line of characters
5512: from the file that we are parsing that represents one entire sheet
5513:
5514: 'bubble line' refers to the data
5515: representing the line of bubbles that are on the physical bubblesheet
5516:
5517:
5518: The overall process is that a scanned in bubblesheet data is uploaded
5519: into a course. When a user wants to grade, they select a
5520: sequence/folder of resources, a file of bubblesheet info, and pick
5521: one of the predefined configurations for what each scanline looks
5522: like.
5523:
5524: Next each scanline is checked for any errors of either 'missing
5525: bubbles' (it's an error because it may have been mis-scanned
5526: because too light bubbling), 'double bubble' (each bubble line should
5527: have no more than one letter picked), invalid or duplicated CODE,
5528: invalid student/employee ID
5529:
5530: If the CODE option is used that determines the randomization of the
5531: homework problems, either way the student/employee ID is looked up into a
5532: username:domain.
5533:
5534: During the validation phase the instructor can choose to skip scanlines.
5535:
5536: After the validation phase, there are now 3 bubblesheet files
5537:
5538: scantron_original_filename (unmodified original file)
5539: scantron_corrected_filename (file where the corrected information has replaced the original information)
5540: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5541:
5542: Also there is a separate hash nohist_scantrondata that contains extra
5543: correction information that isn't representable in the bubblesheet
5544: file (see &scantron_getfile() for more information)
5545:
5546: After all scanlines are either valid, marked as valid or skipped, then
5547: foreach line foreach problem in the picked sequence, an ssi request is
5548: made that simulates a user submitting their selected letter(s) against
5549: the homework problem.

10851: =head1 NAME
10852:
10853: Apache::grades
10854:
10855: =head1 SYNOPSIS
10856:
10857: Handles the viewing of grades.
10858:
10859: This is part of the LearningOnline Network with CAPA project
10860: described at http://www.lon-capa.org.
10861:
10862: =head1 OVERVIEW
10863:
10864: Do an ssi with retries:
10865: While I'd love to factor out this with the vesrion in lonprintout,
10866: 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
10867: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10868:
10869: At least the logic that drives this has been pulled out into loncommon.
10870:
10871:
10872:
10873: ssi_with_retries - Does the server side include of a resource.
10874: if the ssi call returns an error we'll retry it up to
10875: the number of times requested by the caller.
10876: If we still have a problem, no text is appended to the
10877: output and we set some global variables.
10878: to indicate to the caller an SSI error occurred.
10879: All of this is supposed to deal with the issues described
10880: in LON-CAPA BZ 5631 see:
10881: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10882: by informing the user that this happened.
10883:
10884: Parameters:
10885: resource - The resource to include. This is passed directly, without
10886: interpretation to lonnet::ssi.
10887: form - The form hash parameters that guide the interpretation of the resource
10888:
10889: retries - Number of retries allowed before giving up completely.
10890: Returns:
10891: On success, returns the rendered resource identified by the resource parameter.
10892: Side Effects:
10893: The following global variables can be set:
10894: ssi_error - If an unrecoverable error occurred this becomes true.
10895: It is up to the caller to initialize this to false
10896: if desired.
10897: ssi_error_resource - If an unrecoverable error occurred, this is the value
10898: of the resource that could not be rendered by the ssi
10899: call.
10900: ssi_error_message - The error string fetched from the ssi response
10901: in the event of an error.

10911:
10912: =item scantron_get_correction() :
10913:
10914: Builds the interface screen to interact with the operator to fix a
10915: specific error condition in a specific scanline
10916:
10917: Arguments:
10918: $r - Apache request object
10919: $i - number of the current scanline
10920: $scan_record - hash ref as returned from &scantron_parse_scanline()
10921: $scan_config - hash ref as returned from &get_scantron_config()
10922: $line - full contents of the current scanline
10923: $error - error condition, valid values are
10924: 'incorrectCODE', 'duplicateCODE',
10925: 'doublebubble', 'missingbubble',
10926: 'duplicateID', 'incorrectID'
10927: $arg - extra information needed
10928: For errors:
10929: - duplicateID - paper number that this studentID was seen before on
10930: - duplicateCODE - array ref of the paper numbers this CODE was
10931: seen on before
10932: - incorrectCODE - current incorrect CODE
10933: - doublebubble - array ref of the bubble lines that have double
10934: bubble errors
10935: - missingbubble - array ref of the bubble lines that have missing
10936: bubble errors
10937:
10938: $randomorder - True if exam folder has randomorder set
10939: $randompick - True if exam folder has randompick set
10940: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
10941: for current line to question number used for same question
10942: in "Master Seqence" (as seen by Course Coordinator).
10943: $startline - Reference to hash where key is question number (0 is first)
10944: and value is number of first bubble line for current student
10945: or code-based randompick and/or randomorder.
10946:
10947:
10948: =item scantron_get_maxbubble() :
10949:
10950: Arguments:
10951: $nav_error - Reference to scalar which is a flag to indicate a
10952: failure to retrieve a navmap object.
10953: if $nav_error is set to 1 by scantron_get_maxbubble(), the
10954: calling routine should trap the error condition and display the warning
10955: found in &navmap_errormsg().
10956:
10957: $scantron_config - Reference to bubblesheet format configuration hash.
10958:
10959: Returns the maximum number of bubble lines that are expected to
10960: occur. Does this by walking the selected sequence rendering the
10961: resource and then checking &Apache::lonxml::get_problem_counter()
10962: for what the current value of the problem counter is.
10963:
10964: Caches the results to $env{'form.scantron_maxbubble'},
10965: $env{'form.scantron.bubble_lines.n'},
10966: $env{'form.scantron.first_bubble_line.n'} and
10967: $env{"form.scantron.sub_bubblelines.n"}
10968: which are the total number of bubble lines, the number of bubble
10969: lines for response n and number of the first bubble line for response n,
10970: and a comma separated list of numbers of bubble lines for sub-questions
10971: (for optionresponse, matchresponse, and rankresponse items), for response n.
10972:
10973:
10974: =item scantron_validate_missingbubbles() :
10975:
10976: Validates all scanlines in the selected file to not have any
10977: answers that don't have bubbles that have not been verified
10978: to be bubble free.
10979:
10980: =item scantron_process_students() :
10981:
10982: Routine that does the actual grading of the bubblesheet information.
10983:
10984: The parsed scanline hash is added to %env
10985:
10986: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
10987: foreach resource , with the form data of
10988:
10989: 'submitted' =>'scantron'
10990: 'grade_target' =>'grade',
10991: 'grade_username'=> username of student
10992: 'grade_domain' => domain of student
10993: 'grade_courseid'=> of course
10994: 'grade_symb' => symb of resource to grade
10995:
10996: This triggers a grading pass. The problem grading code takes care
10997: of converting the bubbled letter information (now in %env) into a
10998: valid submission.
10999:
11000: =item scantron_upload_scantron_data() :

11016: skipped) for a specific bubblesheet data file that exists in the
11017: course.

11019: =item scantron_validate_ID() :
11020:
11021: Validates all scanlines in the selected file to not have any
11022: invalid or underspecified student/employee IDs
