5499: =head1 Bubble sheet grading routines
5500:
5501: For this documentation:
5502:
5503: 'scanline' refers to the full line of characters
5504: from the file that we are parsing that represents one entire sheet
5505:
5506: 'bubble line' refers to the data
5507: representing the line of bubbles that are on the physical bubblesheet
5508:
5509:
5510: The overall process is that a scanned in bubblesheet data is uploaded
5511: into a course. When a user wants to grade, they select a
5512: sequence/folder of resources, a file of bubblesheet info, and pick
5513: one of the predefined configurations for what each scanline looks
5514: like.
5515:
5516: Next each scanline is checked for any errors of either 'missing
5517: bubbles' (it's an error because it may have been mis-scanned
5518: because too light bubbling), 'double bubble' (each bubble line should
5519: have no more than one letter picked), invalid or duplicated CODE,
5520: invalid student/employee ID
5521:
5522: If the CODE option is used that determines the randomization of the
5523: homework problems, either way the student/employee ID is looked up into a
5524: username:domain.
5525:
5526: During the validation phase the instructor can choose to skip scanlines.
5527:
5528: After the validation phase, there are now 3 bubblesheet files
5529:
5530: scantron_original_filename (unmodified original file)
5531: scantron_corrected_filename (file where the corrected information has replaced the original information)
5532: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5533:
5534: Also there is a separate hash nohist_scantrondata that contains extra
5535: correction information that isn't representable in the bubblesheet
5536: file (see &scantron_getfile() for more information)
5537:
5538: After all scanlines are either valid, marked as valid or skipped, then
5539: foreach line foreach problem in the picked sequence, an ssi request is
5540: made that simulates a user submitting their selected letter(s) against
5541: the homework problem.

6337: and or randompick are in use.
6338: respnumlookup - Ref to hash mapping question numbers in bubble lines
6339: for current line to question number used for same question
6340: in "Master Sequence" (as seen by Course Coordinator).

10843: =head1 NAME
10844:
10845: Apache::grades
10846:
10847: =head1 SYNOPSIS
10848:
10849: Handles the viewing of grades.
10850:
10851: This is part of the LearningOnline Network with CAPA project
10852: described at http://www.lon-capa.org.
10853:
10854: =head1 OVERVIEW
10855:
10856: Do an ssi with retries:
10857: While I'd love to factor out this with the vesrion in lonprintout,
10858: 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
10859: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10860:
10861: At least the logic that drives this has been pulled out into loncommon.
10862:
10863:
10864:
10865: ssi_with_retries - Does the server side include of a resource.
10866: if the ssi call returns an error we'll retry it up to
10867: the number of times requested by the caller.
10868: If we still have a problem, no text is appended to the
10869: output and we set some global variables.
10870: to indicate to the caller an SSI error occurred.
10871: All of this is supposed to deal with the issues described
10872: in LON-CAPA BZ 5631 see:
10873: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10874: by informing the user that this happened.
10875:
10876: Parameters:
10877: resource - The resource to include. This is passed directly, without
10878: interpretation to lonnet::ssi.
10879: form - The form hash parameters that guide the interpretation of the resource
10880:
10881: retries - Number of retries allowed before giving up completely.
10882: Returns:
10883: On success, returns the rendered resource identified by the resource parameter.
10884: Side Effects:
10885: The following global variables can be set:
10886: ssi_error - If an unrecoverable error occurred this becomes true.
10887: It is up to the caller to initialize this to false
10888: if desired.
10889: ssi_error_resource - If an unrecoverable error occurred, this is the value
10890: of the resource that could not be rendered by the ssi
10891: call.
10892: ssi_error_message - The error string fetched from the ssi response
10893: in the event of an error.

10903:
10904: =item scantron_get_correction() :
10905:
10906: Builds the interface screen to interact with the operator to fix a
10907: specific error condition in a specific scanline
10908:
10909: Arguments:
10910: $r - Apache request object
10911: $i - number of the current scanline
10912: $scan_record - hash ref as returned from &scantron_parse_scanline()
10913: $scan_config - hash ref as returned from &get_scantron_config()
10914: $line - full contents of the current scanline
10915: $error - error condition, valid values are
10916: 'incorrectCODE', 'duplicateCODE',
10917: 'doublebubble', 'missingbubble',
10918: 'duplicateID', 'incorrectID'
10919: $arg - extra information needed
10920: For errors:
10921: - duplicateID - paper number that this studentID was seen before on
10922: - duplicateCODE - array ref of the paper numbers this CODE was
10923: seen on before
10924: - incorrectCODE - current incorrect CODE
10925: - doublebubble - array ref of the bubble lines that have double
10926: bubble errors
10927: - missingbubble - array ref of the bubble lines that have missing
10928: bubble errors
10929:
10930: $randomorder - True if exam folder has randomorder set
10931: $randompick - True if exam folder has randompick set
10932: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
10933: for current line to question number used for same question
10934: in "Master Seqence" (as seen by Course Coordinator).
10935: $startline - Reference to hash where key is question number (0 is first)
10936: and value is number of first bubble line for current student
10937: or code-based randompick and/or randomorder.
10938:
10939:
10940: =item scantron_get_maxbubble() :
10941:
10942: Arguments:
10943: $nav_error - Reference to scalar which is a flag to indicate a
10944: failure to retrieve a navmap object.
10945: if $nav_error is set to 1 by scantron_get_maxbubble(), the
10946: calling routine should trap the error condition and display the warning
10947: found in &navmap_errormsg().
10948:
10949: $scantron_config - Reference to bubblesheet format configuration hash.
10950:
10951: Returns the maximum number of bubble lines that are expected to
10952: occur. Does this by walking the selected sequence rendering the
10953: resource and then checking &Apache::lonxml::get_problem_counter()
10954: for what the current value of the problem counter is.
10955:
10956: Caches the results to $env{'form.scantron_maxbubble'},
10957: $env{'form.scantron.bubble_lines.n'},
10958: $env{'form.scantron.first_bubble_line.n'} and
10959: $env{"form.scantron.sub_bubblelines.n"}
10960: which are the total number of bubble lines, the number of bubble
10961: lines for response n and number of the first bubble line for response n,
10962: and a comma separated list of numbers of bubble lines for sub-questions
10963: (for optionresponse, matchresponse, and rankresponse items), for response n.
10964:
10965:
10966: =item scantron_validate_missingbubbles() :
10967:
10968: Validates all scanlines in the selected file to not have any
10969: answers that don't have bubbles that have not been verified
10970: to be bubble free.
10971:
10972: =item scantron_process_students() :
10973:
10974: Routine that does the actual grading of the bubblesheet information.
10975:
10976: The parsed scanline hash is added to %env
10977:
10978: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
10979: foreach resource , with the form data of
10980:
10981: 'submitted' =>'scantron'
10982: 'grade_target' =>'grade',
10983: 'grade_username'=> username of student
10984: 'grade_domain' => domain of student
10985: 'grade_courseid'=> of course
10986: 'grade_symb' => symb of resource to grade
10987:
10988: This triggers a grading pass. The problem grading code takes care
10989: of converting the bubbled letter information (now in %env) into a
10990: valid submission.
10991:
10992: =item scantron_upload_scantron_data() :
