5494: =head1 Bubble sheet grading routines
5495:
5496: For this documentation:
5497:
5498: 'scanline' refers to the full line of characters
5499: from the file that we are parsing that represents one entire sheet
5500:
5501: 'bubble line' refers to the data
5502: representing the line of bubbles that are on the physical bubblesheet
5503:
5504:
5505: The overall process is that a scanned in bubblesheet data is uploaded
5506: into a course. When a user wants to grade, they select a
5507: sequence/folder of resources, a file of bubblesheet info, and pick
5508: one of the predefined configurations for what each scanline looks
5509: like.
5510:
5511: Next each scanline is checked for any errors of either 'missing
5512: bubbles' (it's an error because it may have been mis-scanned
5513: because too light bubbling), 'double bubble' (each bubble line should
5514: have no more than one letter picked), invalid or duplicated CODE,
5515: invalid student/employee ID
5516:
5517: If the CODE option is used that determines the randomization of the
5518: homework problems, either way the student/employee ID is looked up into a
5519: username:domain.
5520:
5521: During the validation phase the instructor can choose to skip scanlines.
5522:
5523: After the validation phase, there are now 3 bubblesheet files
5524:
5525: scantron_original_filename (unmodified original file)
5526: scantron_corrected_filename (file where the corrected information has replaced the original information)
5527: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5528:
5529: Also there is a separate hash nohist_scantrondata that contains extra
5530: correction information that isn't representable in the bubblesheet
5531: file (see &scantron_getfile() for more information)
5532:
5533: After all scanlines are either valid, marked as valid or skipped, then
5534: foreach line foreach problem in the picked sequence, an ssi request is
5535: made that simulates a user submitting their selected letter(s) against
5536: the homework problem.

10829: =head1 NAME
10830:
10831: Apache::grades
10832:
10833: =head1 SYNOPSIS
10834:
10835: Handles the viewing of grades.
10836:
10837: This is part of the LearningOnline Network with CAPA project
10838: described at http://www.lon-capa.org.
10839:
10840: =head1 OVERVIEW
10841:
10842: Do an ssi with retries:
10843: While I'd love to factor out this with the vesrion in lonprintout,
10844: 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
10845: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10846:
10847: At least the logic that drives this has been pulled out into loncommon.
10848:
10849:
10850:
10851: ssi_with_retries - Does the server side include of a resource.
10852: if the ssi call returns an error we'll retry it up to
10853: the number of times requested by the caller.
10854: If we still have a problem, no text is appended to the
10855: output and we set some global variables.
10856: to indicate to the caller an SSI error occurred.
10857: All of this is supposed to deal with the issues described
10858: in LON-CAPA BZ 5631 see:
10859: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10860: by informing the user that this happened.
10861:
10862: Parameters:
10863: resource - The resource to include. This is passed directly, without
10864: interpretation to lonnet::ssi.
10865: form - The form hash parameters that guide the interpretation of the resource
10866:
10867: retries - Number of retries allowed before giving up completely.
10868: Returns:
10869: On success, returns the rendered resource identified by the resource parameter.
10870: Side Effects:
10871: The following global variables can be set:
10872: ssi_error - If an unrecoverable error occurred this becomes true.
10873: It is up to the caller to initialize this to false
10874: if desired.
10875: ssi_error_resource - If an unrecoverable error occurred, this is the value
10876: of the resource that could not be rendered by the ssi
10877: call.
10878: ssi_error_message - The error string fetched from the ssi response
10879: in the event of an error.

10889:
10890: =item scantron_get_correction() :
10891:
10892: Builds the interface screen to interact with the operator to fix a
10893: specific error condition in a specific scanline
10894:
10895: Arguments:
10896: $r - Apache request object
10897: $i - number of the current scanline
10898: $scan_record - hash ref as returned from &scantron_parse_scanline()
10899: $scan_config - hash ref as returned from &get_scantron_config()
10900: $line - full contents of the current scanline
10901: $error - error condition, valid values are
10902: 'incorrectCODE', 'duplicateCODE',
10903: 'doublebubble', 'missingbubble',
10904: 'duplicateID', 'incorrectID'
10905: $arg - extra information needed
10906: For errors:
10907: - duplicateID - paper number that this studentID was seen before on
10908: - duplicateCODE - array ref of the paper numbers this CODE was
10909: seen on before
10910: - incorrectCODE - current incorrect CODE
10911: - doublebubble - array ref of the bubble lines that have double
10912: bubble errors
10913: - missingbubble - array ref of the bubble lines that have missing
10914: bubble errors
10915:
10916: $randomorder - True if exam folder has randomorder set
10917: $randompick - True if exam folder has randompick set
10918: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
10919: for current line to question number used for same question
10920: in "Master Seqence" (as seen by Course Coordinator).
10921: $startline - Reference to hash where key is question number (0 is first)
10922: and value is number of first bubble line for current student
10923: or code-based randompick and/or randomorder.
10924:
10925:
10926: =item scantron_get_maxbubble() :
10927:
10928: Arguments:
10929: $nav_error - Reference to scalar which is a flag to indicate a
10930: failure to retrieve a navmap object.
10931: if $nav_error is set to 1 by scantron_get_maxbubble(), the
10932: calling routine should trap the error condition and display the warning
10933: found in &navmap_errormsg().
10934:
10935: $scantron_config - Reference to bubblesheet format configuration hash.
10936:
10937: Returns the maximum number of bubble lines that are expected to
10938: occur. Does this by walking the selected sequence rendering the
10939: resource and then checking &Apache::lonxml::get_problem_counter()
10940: for what the current value of the problem counter is.
10941:
10942: Caches the results to $env{'form.scantron_maxbubble'},
10943: $env{'form.scantron.bubble_lines.n'},
10944: $env{'form.scantron.first_bubble_line.n'} and
10945: $env{"form.scantron.sub_bubblelines.n"}
10946: which are the total number of bubble lines, the number of bubble
10947: lines for response n and number of the first bubble line for response n,
10948: and a comma separated list of numbers of bubble lines for sub-questions
10949: (for optionresponse, matchresponse, and rankresponse items), for response n.
10950:
10951:
10952: =item scantron_validate_missingbubbles() :
10953:
10954: Validates all scanlines in the selected file to not have any
10955: answers that don't have bubbles that have not been verified
10956: to be bubble free.
10957:
10958: =item scantron_process_students() :
10959:
10960: Routine that does the actual grading of the bubblesheet information.
10961:
10962: The parsed scanline hash is added to %env
10963:
10964: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
10965: foreach resource , with the form data of
10966:
10967: 'submitted' =>'scantron'
10968: 'grade_target' =>'grade',
10969: 'grade_username'=> username of student
10970: 'grade_domain' => domain of student
10971: 'grade_courseid'=> of course
10972: 'grade_symb' => symb of resource to grade
10973:
10974: This triggers a grading pass. The problem grading code takes care
10975: of converting the bubbled letter information (now in %env) into a
10976: valid submission.
10977:
10978: =item scantron_upload_scantron_data() :
