5333: one of the predefined configurations for what each scanline looks
5334: like.
5335:
5336: Next each scanline is checked for any errors of either 'missing
5337: bubbles' (it's an error because it may have been mis-scanned
5338: because too light bubbling), 'double bubble' (each bubble line should
5339: have no more than one letter picked), invalid or duplicated CODE,
5340: invalid student/employee ID
5341:
5342: If the CODE option is used that determines the randomization of the
5343: homework problems, either way the student/employee ID is looked up into a
5344: username:domain.
5345:
5346: During the validation phase the instructor can choose to skip scanlines.
5347:
5348: After the validation phase, there are now 3 bubblesheet files
5349:
5350: scantron_original_filename (unmodified original file)
5351: scantron_corrected_filename (file where the corrected information has replaced the original information)
5352: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5353:
5354: Also there is a separate hash nohist_scantrondata that contains extra
5355: correction information that isn't representable in the bubblesheet
5356: file (see &scantron_getfile() for more information)
5357:
5358: After all scanlines are either valid, marked as valid or skipped, then
5359: foreach line foreach problem in the picked sequence, an ssi request is
5360: made that simulates a user submitting their selected letter(s) against
5361: the homework problem.

7795:
7796: Arguments:
7797: $r - Apache request object.
7798: $question - The question number to prompt for.
7799: $scan_config - The scantron file configuration hash.
7800: $scan_record - Reference to the hash that has the the parsed scanlines.
7801: $error - Type of error
7802: $randomorder - True if randomorder in use.

7817: type problems render as separate sub-questions,
7818: in exam mode. This hash contains a
7819: comma-separated list of the lines per
7820: sub-question.
7821: %responsetype_per_response - essayresponse, formularesponse,
7822: stringresponse, imageresponse, reactionresponse,
7823: and organicresponse type problem parts can have
7824: multiple lines per response if the weight
7825: assigned exceeds 10. In this case, only

7827: than one line might contain bubbles, e.g.
7828: bubbling of: line 1 - J, line 2 - J,

10639: =head1 NAME
10640:
10641: Apache::grades
10642:
10643: =head1 SYNOPSIS
10644:
10645: Handles the viewing of grades.
10646:
10647: This is part of the LearningOnline Network with CAPA project
10648: described at http://www.lon-capa.org.
10649:
10650: =head1 OVERVIEW
10651:
10652: Do an ssi with retries:
10653: While I'd love to factor out this with the vesrion in lonprintout,
10654: 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
10655: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10656:
10657: At least the logic that drives this has been pulled out into loncommon.
10658:
10659:
10660:
10661: ssi_with_retries - Does the server side include of a resource.
10662: if the ssi call returns an error we'll retry it up to
10663: the number of times requested by the caller.
10664: If we still have a problem, no text is appended to the
10665: output and we set some global variables.
10666: to indicate to the caller an SSI error occurred.
10667: All of this is supposed to deal with the issues described
10668: in LON-CAPA BZ 5631 see:
10669: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10670: by informing the user that this happened.
10671:
10672: Parameters:
10673: resource - The resource to include. This is passed directly, without
10674: interpretation to lonnet::ssi.
10675: form - The form hash parameters that guide the interpretation of the resource
10676:
10677: retries - Number of retries allowed before giving up completely.
10678: Returns:
10679: On success, returns the rendered resource identified by the resource parameter.
10680: Side Effects:
10681: The following global variables can be set:
10682: ssi_error - If an unrecoverable error occurred this becomes true.
10683: It is up to the caller to initialize this to false
10684: if desired.
10685: ssi_error_resource - If an unrecoverable error occurred, this is the value
10686: of the resource that could not be rendered by the ssi
10687: call.
10688: ssi_error_message - The error string fetched from the ssi response
10689: in the event of an error.

10701:
10702: Builds the interface screen to interact with the operator to fix a
10703: specific error condition in a specific scanline
10704:
10705: Arguments:
10706: $r - Apache request object
10707: $i - number of the current scanline
10708: $scan_record - hash ref as returned from &scantron_parse_scanline()
10709: $scan_config - hash ref as returned from &get_scantron_config()
10710: $line - full contents of the current scanline
10711: $error - error condition, valid values are
10712: 'incorrectCODE', 'duplicateCODE',
10713: 'doublebubble', 'missingbubble',
10714: 'duplicateID', 'incorrectID'
10715: $arg - extra information needed
10716: For errors:
10717: - duplicateID - paper number that this studentID was seen before on
10718: - duplicateCODE - array ref of the paper numbers this CODE was
10719: seen on before
10720: - incorrectCODE - current incorrect CODE
10721: - doublebubble - array ref of the bubble lines that have double
10722: bubble errors
10723: - missingbubble - array ref of the bubble lines that have missing
10724: bubble errors
10725:
10726: $randomorder - True if exam folder has randomorder set
10727: $randompick - True if exam folder has randompick set
10728: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
10729: for current line to question number used for same question
10730: in "Master Seqence" (as seen by Course Coordinator).
10731: $startline - Reference to hash where key is question number (0 is first)
10732: and value is number of first bubble line for current student
10733: or code-based randompick and/or randomorder.
10734:
10735:
10736: =item scantron_get_maxbubble() :
10737:
10738: Arguments:
10739: $nav_error - Reference to scalar which is a flag to indicate a
10740: failure to retrieve a navmap object.
10741: if $nav_error is set to 1 by scantron_get_maxbubble(), the
10742: calling routine should trap the error condition and display the warning
10743: found in &navmap_errormsg().
10744:
10745: $scantron_config - Reference to bubblesheet format configuration hash.
10746:
10747: Returns the maximum number of bubble lines that are expected to
10748: occur. Does this by walking the selected sequence rendering the
10749: resource and then checking &Apache::lonxml::get_problem_counter()
10750: for what the current value of the problem counter is.
10751:
10752: Caches the results to $env{'form.scantron_maxbubble'},
10753: $env{'form.scantron.bubble_lines.n'},
10754: $env{'form.scantron.first_bubble_line.n'} and
10755: $env{"form.scantron.sub_bubblelines.n"}
10756: which are the total number of bubble lines, the number of bubble
10757: lines for response n and number of the first bubble line for response n,
10758: and a comma separated list of numbers of bubble lines for sub-questions
10759: (for optionresponse, matchresponse, and rankresponse items), for response n.
10760:
10761:
10762: =item scantron_validate_missingbubbles() :
10763:
10764: Validates all scanlines in the selected file to not have any
10765: answers that don't have bubbles that have not been verified
10766: to be bubble free.
10767:
10768: =item scantron_process_students() :
10769:
10770: Routine that does the actual grading of the bubblesheet information.
10771:
10772: The parsed scanline hash is added to %env
10773:
10774: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
10775: foreach resource , with the form data of
10776:
10777: 'submitted' =>'scantron'
10778: 'grade_target' =>'grade',

10780: 'grade_domain' => domain of student
10781: 'grade_courseid'=> of course
10782: 'grade_symb' => symb of resource to grade
10783:
10784: This triggers a grading pass. The problem grading code takes care
10785: of converting the bubbled letter information (now in %env) into a
10786: valid submission.
10787:
10788: =item scantron_upload_scantron_data() :

10804: skipped) for a specific bubblesheet data file that exists in the
10805: course.
10806:
10807: =item scantron_validate_ID() :
10808:
10809: Validates all scanlines in the selected file to not have any
10810: invalid or underspecified student/employee IDs
10811:
10812: =item navmap_errormsg() :
10813:
10814: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
