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

10627: =head1 NAME
10628:
10629: Apache::grades
10630:
10631: =head1 SYNOPSIS
10632:
10633: Handles the viewing of grades.
10634:
10635: This is part of the LearningOnline Network with CAPA project
10636: described at http://www.lon-capa.org.
10637:
10638: =head1 OVERVIEW
10639:
10640: Do an ssi with retries:
10641: While I'd love to factor out this with the vesrion in lonprintout,
10642: 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
10643: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10644:
10645: At least the logic that drives this has been pulled out into loncommon.
10646:
10647:
10648:
10649: ssi_with_retries - Does the server side include of a resource.
10650: if the ssi call returns an error we'll retry it up to
10651: the number of times requested by the caller.
10652: If we still have a problem, no text is appended to the
10653: output and we set some global variables.
10654: to indicate to the caller an SSI error occurred.
10655: All of this is supposed to deal with the issues described
10656: in LON-CAPA BZ 5631 see:
10657: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10658: by informing the user that this happened.
10659:
10660: Parameters:
10661: resource - The resource to include. This is passed directly, without
10662: interpretation to lonnet::ssi.
10663: form - The form hash parameters that guide the interpretation of the resource
10664:
10665: retries - Number of retries allowed before giving up completely.
10666: Returns:
10667: On success, returns the rendered resource identified by the resource parameter.
10668: Side Effects:
10669: The following global variables can be set:
10670: ssi_error - If an unrecoverable error occurred this becomes true.
10671: It is up to the caller to initialize this to false
10672: if desired.
10673: ssi_error_resource - If an unrecoverable error occurred, this is the value
10674: of the resource that could not be rendered by the ssi
10675: call.
10676: ssi_error_message - The error string fetched from the ssi response
10677: in the event of an error.

10688: =item scantron_get_correction() :
10689:
10690: Builds the interface screen to interact with the operator to fix a
10691: specific error condition in a specific scanline
10692:
10693: Arguments:
10694: $r - Apache request object
10695: $i - number of the current scanline
10696: $scan_record - hash ref as returned from &scantron_parse_scanline()
10697: $scan_config - hash ref as returned from &get_scantron_config()
10698: $line - full contents of the current scanline
10699: $error - error condition, valid values are
10700: 'incorrectCODE', 'duplicateCODE',
10701: 'doublebubble', 'missingbubble',
10702: 'duplicateID', 'incorrectID'
10703: $arg - extra information needed
10704: For errors:
10705: - duplicateID - paper number that this studentID was seen before on
10706: - duplicateCODE - array ref of the paper numbers this CODE was
10707: seen on before
10708: - incorrectCODE - current incorrect CODE
10709: - doublebubble - array ref of the bubble lines that have double
10710: bubble errors
10711: - missingbubble - array ref of the bubble lines that have missing
10712: bubble errors
10713:
10714: $randomorder - True if exam folder has randomorder set
10715: $randompick - True if exam folder has randompick set
10716: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
10717: for current line to question number used for same question
10718: in "Master Seqence" (as seen by Course Coordinator).
10719: $startline - Reference to hash where key is question number (0 is first)
10720: and value is number of first bubble line for current student
10721: or code-based randompick and/or randomorder.
10722:
10723:
10724: =item scantron_get_maxbubble() :
10725:
10726: Arguments:
10727: $nav_error - Reference to scalar which is a flag to indicate a
10728: failure to retrieve a navmap object.
10729: if $nav_error is set to 1 by scantron_get_maxbubble(), the
10730: calling routine should trap the error condition and display the warning
10731: found in &navmap_errormsg().
10732:
10733: $scantron_config - Reference to bubblesheet format configuration hash.
10734:
10735: Returns the maximum number of bubble lines that are expected to
10736: occur. Does this by walking the selected sequence rendering the
10737: resource and then checking &Apache::lonxml::get_problem_counter()
10738: for what the current value of the problem counter is.
10739:
10740: Caches the results to $env{'form.scantron_maxbubble'},
10741: $env{'form.scantron.bubble_lines.n'},
10742: $env{'form.scantron.first_bubble_line.n'} and
10743: $env{"form.scantron.sub_bubblelines.n"}
10744: which are the total number of bubble lines, the number of bubble
10745: lines for response n and number of the first bubble line for response n,
10746: and a comma separated list of numbers of bubble lines for sub-questions
10747: (for optionresponse, matchresponse, and rankresponse items), for response n.
10748:
10749:
10750: =item scantron_validate_missingbubbles() :
10751:
10752: Validates all scanlines in the selected file to not have any
10753: answers that don't have bubbles that have not been verified
10754: to be bubble free.
10755:
10756: =item scantron_process_students() :
10757:
10758: Routine that does the actual grading of the bubblesheet information.
10759:
10760: The parsed scanline hash is added to %env
10761:
10762: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
10763: foreach resource , with the form data of
10764:
10765: 'submitted' =>'scantron'
10766: 'grade_target' =>'grade',
10767: 'grade_username'=> username of student
10768: 'grade_domain' => domain of student
10769: 'grade_courseid'=> of course
10770: 'grade_symb' => symb of resource to grade
10771:
10772: This triggers a grading pass. The problem grading code takes care
10773: of converting the bubbled letter information (now in %env) into a
10774: valid submission.
10775:
10776: =item scantron_upload_scantron_data() :

10789: =item scantron_download_scantron_data() :
10790:
10791: Shows a list of the three internal files (original, corrected,
10792: skipped) for a specific bubblesheet data file that exists in the
10793: course.
10794:
10795: =item scantron_validate_ID() :
10796:
10797: Validates all scanlines in the selected file to not have any
10798: invalid or underspecified student/employee IDs
10799:
10800: =item navmap_errormsg() :
10801:
10802: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
