5263: =head1 Bubble sheet grading routines
5264:
5265: For this documentation:
5266:
5267: 'scanline' refers to the full line of characters
5268: from the file that we are parsing that represents one entire sheet
5269:
5270: 'bubble line' refers to the data
5271: representing the line of bubbles that are on the physical bubblesheet
5272:
5273:
5274: The overall process is that a scanned in bubblesheet data is uploaded
5275: into a course. When a user wants to grade, they select a
5276: sequence/folder of resources, a file of bubblesheet info, and pick
5277: one of the predefined configurations for what each scanline looks
5278: like.
5279:
5280: Next each scanline is checked for any errors of either 'missing
5281: bubbles' (it's an error because it may have been mis-scanned
5282: because too light bubbling), 'double bubble' (each bubble line should
5283: have no more than one letter picked), invalid or duplicated CODE,
5284: invalid student/employee ID
5285:
5286: If the CODE option is used that determines the randomization of the
5287: homework problems, either way the student/employee ID is looked up into a
5288: username:domain.
5289:
5290: During the validation phase the instructor can choose to skip scanlines.
5291:
5292: After the validation phase, there are now 3 bubblesheet files
5293:
5294: scantron_original_filename (unmodified original file)
5295: scantron_corrected_filename (file where the corrected information has replaced the original information)
5296: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5297:
5298: Also there is a separate hash nohist_scantrondata that contains extra
5299: correction information that isn't representable in the bubblesheet
5300: file (see &scantron_getfile() for more information)
5301:
5302: After all scanlines are either valid, marked as valid or skipped, then
5303: foreach line foreach problem in the picked sequence, an ssi request is
5304: made that simulates a user submitting their selected letter(s) against
5305: the homework problem.

10574: =head1 NAME
10575:
10576: Apache::grades
10577:
10578: =head1 SYNOPSIS
10579:
10580: Handles the viewing of grades.
10581:
10582: This is part of the LearningOnline Network with CAPA project
10583: described at http://www.lon-capa.org.
10584:
10585: =head1 OVERVIEW
10586:
10587: Do an ssi with retries:
10588: While I'd love to factor out this with the vesrion in lonprintout,
10589: 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
10590: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10591:
10592: At least the logic that drives this has been pulled out into loncommon.
10593:
10594:
10595:
10596: ssi_with_retries - Does the server side include of a resource.
10597: if the ssi call returns an error we'll retry it up to
10598: the number of times requested by the caller.
10599: If we still have a problem, no text is appended to the
10600: output and we set some global variables.
10601: to indicate to the caller an SSI error occurred.
10602: All of this is supposed to deal with the issues described
10603: in LON-CAPA BZ 5631 see:
10604: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10605: by informing the user that this happened.
10606:
10607: Parameters:
10608: resource - The resource to include. This is passed directly, without
10609: interpretation to lonnet::ssi.
10610: form - The form hash parameters that guide the interpretation of the resource
10611:
10612: retries - Number of retries allowed before giving up completely.
10613: Returns:
10614: On success, returns the rendered resource identified by the resource parameter.
10615: Side Effects:
10616: The following global variables can be set:
10617: ssi_error - If an unrecoverable error occurred this becomes true.
10618: It is up to the caller to initialize this to false
10619: if desired.
10620: ssi_error_resource - If an unrecoverable error occurred, this is the value
10621: of the resource that could not be rendered by the ssi
10622: call.
10623: ssi_error_message - The error string fetched from the ssi response
10624: in the event of an error.

10635: =item scantron_get_correction() :
10636:
10637: Builds the interface screen to interact with the operator to fix a
10638: specific error condition in a specific scanline
10639:
10640: Arguments:
10641: $r - Apache request object
10642: $i - number of the current scanline
10643: $scan_record - hash ref as returned from &scantron_parse_scanline()
10644: $scan_config - hash ref as returned from &get_scantron_config()
10645: $line - full contents of the current scanline
10646: $error - error condition, valid values are
10647: 'incorrectCODE', 'duplicateCODE',
10648: 'doublebubble', 'missingbubble',
10649: 'duplicateID', 'incorrectID'
10650: $arg - extra information needed
10651: For errors:
10652: - duplicateID - paper number that this studentID was seen before on
10653: - duplicateCODE - array ref of the paper numbers this CODE was
10654: seen on before
10655: - incorrectCODE - current incorrect CODE
10656: - doublebubble - array ref of the bubble lines that have double
10657: bubble errors
10658: - missingbubble - array ref of the bubble lines that have missing
10659: bubble errors
10660:
10661: $randomorder - True if exam folder has randomorder set
10662: $randompick - True if exam folder has randompick set
10663: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
10664: for current line to question number used for same question
10665: in "Master Seqence" (as seen by Course Coordinator).
10666: $startline - Reference to hash where key is question number (0 is first)
10667: and value is number of first bubble line for current student
10668: or code-based randompick and/or randomorder.
10669:
10670:
10671: =item scantron_get_maxbubble() :
10672:
10673: Arguments:
10674: $nav_error - Reference to scalar which is a flag to indicate a
10675: failure to retrieve a navmap object.
10676: if $nav_error is set to 1 by scantron_get_maxbubble(), the
10677: calling routine should trap the error condition and display the warning
10678: found in &navmap_errormsg().
10679:
10680: $scantron_config - Reference to bubblesheet format configuration hash.
10681:
10682: Returns the maximum number of bubble lines that are expected to
10683: occur. Does this by walking the selected sequence rendering the
10684: resource and then checking &Apache::lonxml::get_problem_counter()
10685: for what the current value of the problem counter is.
10686:
10687: Caches the results to $env{'form.scantron_maxbubble'},
10688: $env{'form.scantron.bubble_lines.n'},
10689: $env{'form.scantron.first_bubble_line.n'} and
10690: $env{"form.scantron.sub_bubblelines.n"}
10691: which are the total number of bubble lines, the number of bubble
10692: lines for response n and number of the first bubble line for response n,
10693: and a comma separated list of numbers of bubble lines for sub-questions
10694: (for optionresponse, matchresponse, and rankresponse items), for response n.
10695:
10696:
10697: =item scantron_validate_missingbubbles() :
10698:
10699: Validates all scanlines in the selected file to not have any
10700: answers that don't have bubbles that have not been verified
10701: to be bubble free.
10702:
10703: =item scantron_process_students() :
10704:
10705: Routine that does the actual grading of the bubblesheet information.
10706:
10707: The parsed scanline hash is added to %env
10708:
10709: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
10710: foreach resource , with the form data of
10711:
10712: 'submitted' =>'scantron'
10713: 'grade_target' =>'grade',
10714: 'grade_username'=> username of student
10715: 'grade_domain' => domain of student
10716: 'grade_courseid'=> of course
10717: 'grade_symb' => symb of resource to grade
10718:
10719: This triggers a grading pass. The problem grading code takes care
10720: of converting the bubbled letter information (now in %env) into a
10721: valid submission.
10722:
10723: =item scantron_upload_scantron_data() :

10738: Shows a list of the three internal files (original, corrected,
10739: skipped) for a specific bubblesheet data file that exists in the
10740: course.
10741:
10742: =item scantron_validate_ID() :
10743:
10744: Validates all scanlines in the selected file to not have any
10745: invalid or underspecified student/employee IDs
10746:
10747: =item navmap_errormsg() :
