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.

10884: =head1 NAME
10885:
10886: Apache::grades
10887:
10888: =head1 SYNOPSIS
10889:
10890: Handles the viewing of grades.
10891:
10892: This is part of the LearningOnline Network with CAPA project
10893: described at http://www.lon-capa.org.
10894:
10895: =head1 OVERVIEW
10896:
10897: Do an ssi with retries:
10898: While I'd love to factor out this with the vesrion in lonprintout,
10899: 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
10900: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10901:
10902: At least the logic that drives this has been pulled out into loncommon.
10903:
10904:
10905:
10906: ssi_with_retries - Does the server side include of a resource.
10907: if the ssi call returns an error we'll retry it up to
10908: the number of times requested by the caller.
10909: If we still have a problem, no text is appended to the
10910: output and we set some global variables.
10911: to indicate to the caller an SSI error occurred.
10912: All of this is supposed to deal with the issues described
10913: in LON-CAPA BZ 5631 see:
10914: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10915: by informing the user that this happened.
10916:
10917: Parameters:
10918: resource - The resource to include. This is passed directly, without
10919: interpretation to lonnet::ssi.
10920: form - The form hash parameters that guide the interpretation of the resource
10921:
10922: retries - Number of retries allowed before giving up completely.
10923: Returns:
10924: On success, returns the rendered resource identified by the resource parameter.
10925: Side Effects:
10926: The following global variables can be set:
10927: ssi_error - If an unrecoverable error occurred this becomes true.
10928: It is up to the caller to initialize this to false
10929: if desired.
10930: ssi_error_resource - If an unrecoverable error occurred, this is the value
10931: of the resource that could not be rendered by the ssi
10932: call.
10933: ssi_error_message - The error string fetched from the ssi response
10934: in the event of an error.

10944:
10945: =item scantron_get_correction() :
10946:
10947: Builds the interface screen to interact with the operator to fix a
10948: specific error condition in a specific scanline
10949:
10950: Arguments:
10951: $r - Apache request object
10952: $i - number of the current scanline
10953: $scan_record - hash ref as returned from &scantron_parse_scanline()
10954: $scan_config - hash ref as returned from &Apache::lonnet::get_scantron_config()
10955: $line - full contents of the current scanline
10956: $error - error condition, valid values are
10957: 'incorrectCODE', 'duplicateCODE',
10958: 'doublebubble', 'missingbubble',
10959: 'duplicateID', 'incorrectID'
10960: $arg - extra information needed
10961: For errors:
10962: - duplicateID - paper number that this studentID was seen before on
10963: - duplicateCODE - array ref of the paper numbers this CODE was
10964: seen on before
10965: - incorrectCODE - current incorrect CODE
10966: - doublebubble - array ref of the bubble lines that have double
10967: bubble errors
10968: - missingbubble - array ref of the bubble lines that have missing
10969: bubble errors
10970:
10971: $randomorder - True if exam folder has randomorder set
10972: $randompick - True if exam folder has randompick set
10973: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
10974: for current line to question number used for same question
10975: in "Master Seqence" (as seen by Course Coordinator).
10976: $startline - Reference to hash where key is question number (0 is first)
10977: and value is number of first bubble line for current student
10978: or code-based randompick and/or randomorder.
10979:
10980:
10981: =item scantron_get_maxbubble() :
10982:
10983: Arguments:
10984: $nav_error - Reference to scalar which is a flag to indicate a
10985: failure to retrieve a navmap object.
10986: if $nav_error is set to 1 by scantron_get_maxbubble(), the
10987: calling routine should trap the error condition and display the warning
10988: found in &navmap_errormsg().
10989:
10990: $scantron_config - Reference to bubblesheet format configuration hash.
10991:
10992: Returns the maximum number of bubble lines that are expected to
10993: occur. Does this by walking the selected sequence rendering the
10994: resource and then checking &Apache::lonxml::get_problem_counter()
10995: for what the current value of the problem counter is.
10996:
10997: Caches the results to $env{'form.scantron_maxbubble'},
10998: $env{'form.scantron.bubble_lines.n'},
10999: $env{'form.scantron.first_bubble_line.n'} and
11000: $env{"form.scantron.sub_bubblelines.n"}
11001: which are the total number of bubble lines, the number of bubble
11002: lines for response n and number of the first bubble line for response n,
11003: and a comma separated list of numbers of bubble lines for sub-questions
11004: (for optionresponse, matchresponse, and rankresponse items), for response n.
11005:
11006:
11007: =item scantron_validate_missingbubbles() :
11008:
11009: Validates all scanlines in the selected file to not have any
11010: answers that don't have bubbles that have not been verified
11011: to be bubble free.
11012:
11013: =item scantron_process_students() :
11014:
11015: Routine that does the actual grading of the bubblesheet information.
11016:
11017: The parsed scanline hash is added to %env
11018:
11019: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
11020: foreach resource , with the form data of
11021:
11022: 'submitted' =>'scantron'
11023: 'grade_target' =>'grade',
11024: 'grade_username'=> username of student
11025: 'grade_domain' => domain of student
11026: 'grade_courseid'=> of course
11027: 'grade_symb' => symb of resource to grade
11028:
11029: This triggers a grading pass. The problem grading code takes care
11030: of converting the bubbled letter information (now in %env) into a
11031: valid submission.
11032:
11033: =item scantron_upload_scantron_data() :

11047:
11048: Shows a list of the three internal files (original, corrected,
11049: skipped) for a specific bubblesheet data file that exists in the
11050: course.
11051:
11052: =item scantron_validate_ID() :
11053:
11054: Validates all scanlines in the selected file to not have any
11055: invalid or underspecified student/employee IDs
11056:
11057: =item navmap_errormsg() :
11058:
11059: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
