5319:
5320: 'scanline' refers to the full line of characters
5321: from the file that we are parsing that represents one entire sheet
5322:
5323: 'bubble line' refers to the data
5324: representing the line of bubbles that are on the physical bubblesheet
5325:
5326:
5327: The overall process is that a scanned in bubblesheet data is uploaded
5328: into a course. When a user wants to grade, they select a
5329: sequence/folder of resources, a file of bubblesheet info, and pick
5330: one of the predefined configurations for what each scanline looks
5331: like.
5332:
5333: Next each scanline is checked for any errors of either 'missing
5334: bubbles' (it's an error because it may have been mis-scanned

10636: =head1 NAME
10637:
10638: Apache::grades
10639:
10640: =head1 SYNOPSIS
10641:
10642: Handles the viewing of grades.
10643:
10644: This is part of the LearningOnline Network with CAPA project
10645: described at http://www.lon-capa.org.
10646:
10647: =head1 OVERVIEW
10648:
10649: Do an ssi with retries:
10650: While I'd love to factor out this with the vesrion in lonprintout,
10651: 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
10652: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10653:
10654: At least the logic that drives this has been pulled out into loncommon.
10655:
10656:
10657:
10658: ssi_with_retries - Does the server side include of a resource.
10659: if the ssi call returns an error we'll retry it up to
10660: the number of times requested by the caller.
10661: If we still have a problem, no text is appended to the
10662: output and we set some global variables.
10663: to indicate to the caller an SSI error occurred.
10664: All of this is supposed to deal with the issues described
10665: in LON-CAPA BZ 5631 see:
10666: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10667: by informing the user that this happened.
10668:
10669: Parameters:
10670: resource - The resource to include. This is passed directly, without
10671: interpretation to lonnet::ssi.
10672: form - The form hash parameters that guide the interpretation of the resource
10673:
10674: retries - Number of retries allowed before giving up completely.
10675: Returns:
10676: On success, returns the rendered resource identified by the resource parameter.
10677: Side Effects:
10678: The following global variables can be set:
10679: ssi_error - If an unrecoverable error occurred this becomes true.
10680: It is up to the caller to initialize this to false
10681: if desired.
10682: ssi_error_resource - If an unrecoverable error occurred, this is the value
10683: of the resource that could not be rendered by the ssi
10684: call.
10685: ssi_error_message - The error string fetched from the ssi response
10686: in the event of an error.

10698:
10699: Builds the interface screen to interact with the operator to fix a
10700: specific error condition in a specific scanline
10701:
10702: Arguments:
10703: $r - Apache request object
10704: $i - number of the current scanline
10705: $scan_record - hash ref as returned from &scantron_parse_scanline()
10706: $scan_config - hash ref as returned from &get_scantron_config()
10707: $line - full contents of the current scanline
10708: $error - error condition, valid values are
10709: 'incorrectCODE', 'duplicateCODE',
10710: 'doublebubble', 'missingbubble',
10711: 'duplicateID', 'incorrectID'
10712: $arg - extra information needed
10713: For errors:
10714: - duplicateID - paper number that this studentID was seen before on
10715: - duplicateCODE - array ref of the paper numbers this CODE was
10716: seen on before
10717: - incorrectCODE - current incorrect CODE
10718: - doublebubble - array ref of the bubble lines that have double
10719: bubble errors
10720: - missingbubble - array ref of the bubble lines that have missing
10721: bubble errors
10722:
10723: $randomorder - True if exam folder has randomorder set
10724: $randompick - True if exam folder has randompick set
10725: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
10726: for current line to question number used for same question
10727: in "Master Seqence" (as seen by Course Coordinator).
10728: $startline - Reference to hash where key is question number (0 is first)
10729: and value is number of first bubble line for current student
10730: or code-based randompick and/or randomorder.
10731:
10732:
10733: =item scantron_get_maxbubble() :
10734:
10735: Arguments:
10736: $nav_error - Reference to scalar which is a flag to indicate a
10737: failure to retrieve a navmap object.
10738: if $nav_error is set to 1 by scantron_get_maxbubble(), the
10739: calling routine should trap the error condition and display the warning
10740: found in &navmap_errormsg().
10741:
10742: $scantron_config - Reference to bubblesheet format configuration hash.
10743:
10744: Returns the maximum number of bubble lines that are expected to
10745: occur. Does this by walking the selected sequence rendering the
10746: resource and then checking &Apache::lonxml::get_problem_counter()
10747: for what the current value of the problem counter is.
10748:
10749: Caches the results to $env{'form.scantron_maxbubble'},
10750: $env{'form.scantron.bubble_lines.n'},
10751: $env{'form.scantron.first_bubble_line.n'} and
10752: $env{"form.scantron.sub_bubblelines.n"}
10753: which are the total number of bubble lines, the number of bubble
10754: lines for response n and number of the first bubble line for response n,
10755: and a comma separated list of numbers of bubble lines for sub-questions
10756: (for optionresponse, matchresponse, and rankresponse items), for response n.
10757:
10758:
10759: =item scantron_validate_missingbubbles() :
10760:
10761: Validates all scanlines in the selected file to not have any
10762: answers that don't have bubbles that have not been verified
10763: to be bubble free.
10764:
10765: =item scantron_process_students() :
10766:
10767: Routine that does the actual grading of the bubblesheet information.
10768:
10769: The parsed scanline hash is added to %env
10770:
10771: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
10772: foreach resource , with the form data of
10773:
10774: 'submitted' =>'scantron'
10775: 'grade_target' =>'grade',
10776: 'grade_username'=> username of student
10777: 'grade_domain' => domain of student
10778: 'grade_courseid'=> of course
10779: 'grade_symb' => symb of resource to grade
10780:
10781: This triggers a grading pass. The problem grading code takes care
10782: of converting the bubbled letter information (now in %env) into a
10783: valid submission.
10784:
10785: =item scantron_upload_scantron_data() :

10799:
10800: Shows a list of the three internal files (original, corrected,
10801: skipped) for a specific bubblesheet data file that exists in the
10802: course.
10803:
10804: =item scantron_validate_ID() :
10805:
10806: Validates all scanlines in the selected file to not have any
10807: invalid or underspecified student/employee IDs
10808:
10809: =item navmap_errormsg() :
10810:
10811: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
