5492: =head1 Bubble sheet grading routines
5493:
5494: For this documentation:
5495:
5496: 'scanline' refers to the full line of characters
5497: from the file that we are parsing that represents one entire sheet
5498:
5499: 'bubble line' refers to the data
5500: representing the line of bubbles that are on the physical bubblesheet
5501:
5502:
5503: The overall process is that a scanned in bubblesheet data is uploaded
5504: into a course. When a user wants to grade, they select a
5505: sequence/folder of resources, a file of bubblesheet info, and pick
5506: one of the predefined configurations for what each scanline looks
5507: like.
5508:
5509: Next each scanline is checked for any errors of either 'missing
5510: bubbles' (it's an error because it may have been mis-scanned
5511: because too light bubbling), 'double bubble' (each bubble line should
5512: have no more than one letter picked), invalid or duplicated CODE,
5513: invalid student/employee ID
5514:
5515: If the CODE option is used that determines the randomization of the
5516: homework problems, either way the student/employee ID is looked up into a
5517: username:domain.
5518:
5519: During the validation phase the instructor can choose to skip scanlines.
5520:
5521: After the validation phase, there are now 3 bubblesheet files
5522:
5523: scantron_original_filename (unmodified original file)
5524: scantron_corrected_filename (file where the corrected information has replaced the original information)
5525: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5526:
5527: Also there is a separate hash nohist_scantrondata that contains extra
5528: correction information that isn't representable in the bubblesheet
5529: file (see &scantron_getfile() for more information)
5530:
5531: After all scanlines are either valid, marked as valid or skipped, then
5532: foreach line foreach problem in the picked sequence, an ssi request is
5533: made that simulates a user submitting their selected letter(s) against
5534: the homework problem.

6330: and or randompick are in use.
6331: respnumlookup - Ref to hash mapping question numbers in bubble lines
6332: for current line to question number used for same question
6333: in "Master Sequence" (as seen by Course Coordinator).

10827: =head1 NAME
10828:
10829: Apache::grades
10830:
10831: =head1 SYNOPSIS
10832:
10833: Handles the viewing of grades.
10834:
10835: This is part of the LearningOnline Network with CAPA project
10836: described at http://www.lon-capa.org.
10837:
10838: =head1 OVERVIEW
10839:
10840: Do an ssi with retries:
10841: While I'd love to factor out this with the vesrion in lonprintout,
10842: 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
10843: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10844:
10845: At least the logic that drives this has been pulled out into loncommon.
10846:
10847:
10848:
10849: ssi_with_retries - Does the server side include of a resource.
10850: if the ssi call returns an error we'll retry it up to
10851: the number of times requested by the caller.
10852: If we still have a problem, no text is appended to the
10853: output and we set some global variables.
10854: to indicate to the caller an SSI error occurred.
10855: All of this is supposed to deal with the issues described
10856: in LON-CAPA BZ 5631 see:
10857: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10858: by informing the user that this happened.
10859:
10860: Parameters:
10861: resource - The resource to include. This is passed directly, without
10862: interpretation to lonnet::ssi.
10863: form - The form hash parameters that guide the interpretation of the resource
10864:
10865: retries - Number of retries allowed before giving up completely.
10866: Returns:
10867: On success, returns the rendered resource identified by the resource parameter.
10868: Side Effects:
10869: The following global variables can be set:
10870: ssi_error - If an unrecoverable error occurred this becomes true.
10871: It is up to the caller to initialize this to false
10872: if desired.
10873: ssi_error_resource - If an unrecoverable error occurred, this is the value
10874: of the resource that could not be rendered by the ssi
10875: call.
10876: ssi_error_message - The error string fetched from the ssi response
10877: in the event of an error.

10887:
10888: =item scantron_get_correction() :
10889:
10890: Builds the interface screen to interact with the operator to fix a
10891: specific error condition in a specific scanline
10892:
10893: Arguments:
10894: $r - Apache request object
10895: $i - number of the current scanline
10896: $scan_record - hash ref as returned from &scantron_parse_scanline()
10897: $scan_config - hash ref as returned from &get_scantron_config()
10898: $line - full contents of the current scanline
10899: $error - error condition, valid values are
10900: 'incorrectCODE', 'duplicateCODE',
10901: 'doublebubble', 'missingbubble',
10902: 'duplicateID', 'incorrectID'
10903: $arg - extra information needed
10904: For errors:
10905: - duplicateID - paper number that this studentID was seen before on
10906: - duplicateCODE - array ref of the paper numbers this CODE was
10907: seen on before
10908: - incorrectCODE - current incorrect CODE
10909: - doublebubble - array ref of the bubble lines that have double
10910: bubble errors
10911: - missingbubble - array ref of the bubble lines that have missing
10912: bubble errors
10913:
10914: $randomorder - True if exam folder has randomorder set
10915: $randompick - True if exam folder has randompick set
10916: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
10917: for current line to question number used for same question
10918: in "Master Seqence" (as seen by Course Coordinator).
10919: $startline - Reference to hash where key is question number (0 is first)
10920: and value is number of first bubble line for current student
10921: or code-based randompick and/or randomorder.
10922:
10923:
10924: =item scantron_get_maxbubble() :
10925:
10926: Arguments:
10927: $nav_error - Reference to scalar which is a flag to indicate a
10928: failure to retrieve a navmap object.
10929: if $nav_error is set to 1 by scantron_get_maxbubble(), the
10930: calling routine should trap the error condition and display the warning
10931: found in &navmap_errormsg().
10932:
10933: $scantron_config - Reference to bubblesheet format configuration hash.
10934:
10935: Returns the maximum number of bubble lines that are expected to
10936: occur. Does this by walking the selected sequence rendering the
10937: resource and then checking &Apache::lonxml::get_problem_counter()
10938: for what the current value of the problem counter is.
10939:
10940: Caches the results to $env{'form.scantron_maxbubble'},
10941: $env{'form.scantron.bubble_lines.n'},
10942: $env{'form.scantron.first_bubble_line.n'} and
10943: $env{"form.scantron.sub_bubblelines.n"}
10944: which are the total number of bubble lines, the number of bubble
10945: lines for response n and number of the first bubble line for response n,
10946: and a comma separated list of numbers of bubble lines for sub-questions
10947: (for optionresponse, matchresponse, and rankresponse items), for response n.
10948:
10949:
10950: =item scantron_validate_missingbubbles() :
10951:
10952: Validates all scanlines in the selected file to not have any
10953: answers that don't have bubbles that have not been verified
10954: to be bubble free.
10955:
10956: =item scantron_process_students() :
10957:
10958: Routine that does the actual grading of the bubblesheet information.
10959:
10960: The parsed scanline hash is added to %env
10961:
10962: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
10963: foreach resource , with the form data of
10964:
10965: 'submitted' =>'scantron'
10966: 'grade_target' =>'grade',
10967: 'grade_username'=> username of student
10968: 'grade_domain' => domain of student
10969: 'grade_courseid'=> of course
10970: 'grade_symb' => symb of resource to grade
10971:
10972: This triggers a grading pass. The problem grading code takes care
10973: of converting the bubbled letter information (now in %env) into a
10974: valid submission.
10975:
10976: =item scantron_upload_scantron_data() :
