5333: =head1 Bubble sheet grading routines
5334:
5335: For this documentation:
5336:
5337: 'scanline' refers to the full line of characters
5338: from the file that we are parsing that represents one entire sheet
5339:
5340: 'bubble line' refers to the data
5341: representing the line of bubbles that are on the physical bubblesheet
5342:
5343:
5344: The overall process is that a scanned in bubblesheet data is uploaded
5345: into a course. When a user wants to grade, they select a
5346: sequence/folder of resources, a file of bubblesheet info, and pick
5347: one of the predefined configurations for what each scanline looks
5348: like.
5349:
5350: Next each scanline is checked for any errors of either 'missing
5351: bubbles' (it's an error because it may have been mis-scanned
5352: because too light bubbling), 'double bubble' (each bubble line should
5353: have no more than one letter picked), invalid or duplicated CODE,
5354: invalid student/employee ID
5355:
5356: If the CODE option is used that determines the randomization of the
5357: homework problems, either way the student/employee ID is looked up into a
5358: username:domain.
5359:
5360: During the validation phase the instructor can choose to skip scanlines.
5361:
5362: After the validation phase, there are now 3 bubblesheet files
5363:
5364: scantron_original_filename (unmodified original file)
5365: scantron_corrected_filename (file where the corrected information has replaced the original information)
5366: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5367:
5368: Also there is a separate hash nohist_scantrondata that contains extra
5369: correction information that isn't representable in the bubblesheet
5370: file (see &scantron_getfile() for more information)
5371:
5372: After all scanlines are either valid, marked as valid or skipped, then
5373: foreach line foreach problem in the picked sequence, an ssi request is
5374: made that simulates a user submitting their selected letter(s) against
5375: the homework problem.

10658: =head1 NAME
10659:
10660: Apache::grades
10661:
10662: =head1 SYNOPSIS
10663:
10664: Handles the viewing of grades.
10665:
10666: This is part of the LearningOnline Network with CAPA project
10667: described at http://www.lon-capa.org.
10668:
10669: =head1 OVERVIEW
10670:
10671: Do an ssi with retries:
10672: While I'd love to factor out this with the vesrion in lonprintout,
10673: 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
10674: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10675:
10676: At least the logic that drives this has been pulled out into loncommon.
10677:
10678:
10679:
10680: ssi_with_retries - Does the server side include of a resource.
10681: if the ssi call returns an error we'll retry it up to
10682: the number of times requested by the caller.
10683: If we still have a problem, no text is appended to the
10684: output and we set some global variables.
10685: to indicate to the caller an SSI error occurred.
10686: All of this is supposed to deal with the issues described
10687: in LON-CAPA BZ 5631 see:
10688: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10689: by informing the user that this happened.
10690:
10691: Parameters:
10692: resource - The resource to include. This is passed directly, without
10693: interpretation to lonnet::ssi.
10694: form - The form hash parameters that guide the interpretation of the resource
10695:
10696: retries - Number of retries allowed before giving up completely.
10697: Returns:
10698: On success, returns the rendered resource identified by the resource parameter.
10699: Side Effects:
10700: The following global variables can be set:
10701: ssi_error - If an unrecoverable error occurred this becomes true.
10702: It is up to the caller to initialize this to false
10703: if desired.
10704: ssi_error_resource - If an unrecoverable error occurred, this is the value
10705: of the resource that could not be rendered by the ssi
10706: call.
10707: ssi_error_message - The error string fetched from the ssi response
10708: in the event of an error.

10720:
10721: Builds the interface screen to interact with the operator to fix a
10722: specific error condition in a specific scanline
10723:
10724: Arguments:
10725: $r - Apache request object
10726: $i - number of the current scanline
10727: $scan_record - hash ref as returned from &scantron_parse_scanline()
10728: $scan_config - hash ref as returned from &get_scantron_config()
10729: $line - full contents of the current scanline
10730: $error - error condition, valid values are
10731: 'incorrectCODE', 'duplicateCODE',
10732: 'doublebubble', 'missingbubble',
10733: 'duplicateID', 'incorrectID'
10734: $arg - extra information needed
10735: For errors:
10736: - duplicateID - paper number that this studentID was seen before on
10737: - duplicateCODE - array ref of the paper numbers this CODE was
10738: seen on before
10739: - incorrectCODE - current incorrect CODE
10740: - doublebubble - array ref of the bubble lines that have double
10741: bubble errors
10742: - missingbubble - array ref of the bubble lines that have missing
10743: bubble errors
10744:
10745: $randomorder - True if exam folder has randomorder set
10746: $randompick - True if exam folder has randompick set
10747: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
10748: for current line to question number used for same question
10749: in "Master Seqence" (as seen by Course Coordinator).
10750: $startline - Reference to hash where key is question number (0 is first)
10751: and value is number of first bubble line for current student
10752: or code-based randompick and/or randomorder.
10753:
10754:
10755: =item scantron_get_maxbubble() :
10756:
10757: Arguments:
10758: $nav_error - Reference to scalar which is a flag to indicate a
10759: failure to retrieve a navmap object.
10760: if $nav_error is set to 1 by scantron_get_maxbubble(), the
10761: calling routine should trap the error condition and display the warning
10762: found in &navmap_errormsg().
10763:
10764: $scantron_config - Reference to bubblesheet format configuration hash.
10765:
10766: Returns the maximum number of bubble lines that are expected to
10767: occur. Does this by walking the selected sequence rendering the
10768: resource and then checking &Apache::lonxml::get_problem_counter()
10769: for what the current value of the problem counter is.
10770:
10771: Caches the results to $env{'form.scantron_maxbubble'},
10772: $env{'form.scantron.bubble_lines.n'},
10773: $env{'form.scantron.first_bubble_line.n'} and
10774: $env{"form.scantron.sub_bubblelines.n"}
10775: which are the total number of bubble lines, the number of bubble
10776: lines for response n and number of the first bubble line for response n,
10777: and a comma separated list of numbers of bubble lines for sub-questions
10778: (for optionresponse, matchresponse, and rankresponse items), for response n.
10779:
10780:
10781: =item scantron_validate_missingbubbles() :
10782:
10783: Validates all scanlines in the selected file to not have any
10784: answers that don't have bubbles that have not been verified
10785: to be bubble free.
10786:
10787: =item scantron_process_students() :
10788:
10789: Routine that does the actual grading of the bubblesheet information.
10790:
10791: The parsed scanline hash is added to %env
10792:
10793: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
10794: foreach resource , with the form data of
10795:
10796: 'submitted' =>'scantron'
10797: 'grade_target' =>'grade',

10799: 'grade_domain' => domain of student
10800: 'grade_courseid'=> of course
10801: 'grade_symb' => symb of resource to grade
10802:
10803: This triggers a grading pass. The problem grading code takes care
10804: of converting the bubbled letter information (now in %env) into a
10805: valid submission.
10806:
10807: =item scantron_upload_scantron_data() :
