Improvements to bubblesheet grading and related localization
- Warning style for warning messages
- Use monospace font for mismatch table to allow proper comparison of mismatching grading data
- Move html tags outside phrase to be translated
- Move dynamic data outside phrase to be translated to actually allow translation
- Correct unbalanced tags (<p>)
- Consistent wording "Bubblesheet"

4832: =head1 Bubble sheet grading routines
4833:
4834: For this documentation:
4835:
4836: 'scanline' refers to the full line of characters
4837: from the file that we are parsing that represents one entire sheet
4838:
4839: 'bubble line' refers to the data
4840: representing the line of bubbles that are on the physical bubble sheet
4841:
4842:
4843: The overall process is that a scanned in bubble sheet data is uploaded
4844: into a course. When a user wants to grade, they select a
4845: sequence/folder of resources, a file of bubble sheet info, and pick
4846: one of the predefined configurations for what each scanline looks
4847: like.
4848:
4849: Next each scanline is checked for any errors of either 'missing
4850: bubbles' (it's an error because it may have been mis-scanned
4851: because too light bubbling), 'double bubble' (each bubble line should
4852: have no more that one letter picked), invalid or duplicated CODE,
4853: invalid student/employee ID
4854:
4855: If the CODE option is used that determines the randomization of the
4856: homework problems, either way the student/employee ID is looked up into a
4857: username:domain.
4858:
4859: During the validation phase the instructor can choose to skip scanlines.
4860:
4861: After the validation phase, there are now 3 bubble sheet files
4862:
4863: scantron_original_filename (unmodified original file)
4864: scantron_corrected_filename (file where the corrected information has replaced the original information)
4865: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4866:
4867: Also there is a separate hash nohist_scantrondata that contains extra
4868: correction information that isn't representable in the bubble sheet
4869: file (see &scantron_getfile() for more information)
4870:
4871: After all scanlines are either valid, marked as valid or skipped, then
4872: foreach line foreach problem in the picked sequence, an ssi request is
4873: made that simulates a user submitting their selected letter(s) against
4874: the homework problem.

9523: =head1 NAME
9524:
9525: Apache::grades
9526:
9527: =head1 SYNOPSIS
9528:
9529: Handles the viewing of grades.
9530:
9531: This is part of the LearningOnline Network with CAPA project
9532: described at http://www.lon-capa.org.
9533:
9534: =head1 OVERVIEW
9535:
9536: Do an ssi with retries:
9537: While I'd love to factor out this with the vesrion in lonprintout,
9538: 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
9539: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9540:
9541: At least the logic that drives this has been pulled out into loncommon.
9542:
9543:
9544:
9545: ssi_with_retries - Does the server side include of a resource.
9546: if the ssi call returns an error we'll retry it up to
9547: the number of times requested by the caller.
9548: If we still have a proble, no text is appended to the
9549: output and we set some global variables.
9550: to indicate to the caller an SSI error occurred.
9551: All of this is supposed to deal with the issues described
9552: in LonCAPA BZ 5631 see:
9553: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9554: by informing the user that this happened.
9555:
9556: Parameters:
9557: resource - The resource to include. This is passed directly, without
9558: interpretation to lonnet::ssi.
9559: form - The form hash parameters that guide the interpretation of the resource
9560:
9561: retries - Number of retries allowed before giving up completely.
9562: Returns:
9563: On success, returns the rendered resource identified by the resource parameter.
9564: Side Effects:
9565: The following global variables can be set:
9566: ssi_error - If an unrecoverable error occurred this becomes true.
9567: It is up to the caller to initialize this to false
9568: if desired.
9569: ssi_error_resource - If an unrecoverable error occurred, this is the value
9570: of the resource that could not be rendered by the ssi
9571: call.
9572: ssi_error_message - The error string fetched from the ssi response
9573: in the event of an error.

9581:
9582: =over
9583:
9584: =item scantron_get_correction() :
9585:
9586: Builds the interface screen to interact with the operator to fix a
9587: specific error condition in a specific scanline
9588:
9589: Arguments:
9590: $r - Apache request object
9591: $i - number of the current scanline
9592: $scan_record - hash ref as returned from &scantron_parse_scanline()
9593: $scan_config - hash ref as returned from &get_scantron_config()
9594: $line - full contents of the current scanline
9595: $error - error condition, valid values are
9596: 'incorrectCODE', 'duplicateCODE',
9597: 'doublebubble', 'missingbubble',
9598: 'duplicateID', 'incorrectID'
9599: $arg - extra information needed
9600: For errors:
9601: - duplicateID - paper number that this studentID was seen before on
9602: - duplicateCODE - array ref of the paper numbers this CODE was
9603: seen on before
9604: - incorrectCODE - current incorrect CODE
9605: - doublebubble - array ref of the bubble lines that have double
9606: bubble errors
9607: - missingbubble - array ref of the bubble lines that have missing
9608: bubble errors
9609:
9610: =item scantron_get_maxbubble() :
9611:
9612: Arguments:
9613: $nav_error - Reference to scalar which is a flag to indicate a
9614: failure to retrieve a navmap object.
9615: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9616: calling routine should trap the error condition and display the warning
9617: found in &navmap_errormsg().
9618:
9619: $scantron_config - Reference to bubblesheet format configuration hash.
9620:
9621: Returns the maximum number of bubble lines that are expected to
9622: occur. Does this by walking the selected sequence rendering the
9623: resource and then checking &Apache::lonxml::get_problem_counter()
9624: for what the current value of the problem counter is.
9625:
9626: Caches the results to $env{'form.scantron_maxbubble'},
9627: $env{'form.scantron.bubble_lines.n'},
9628: $env{'form.scantron.first_bubble_line.n'} and
9629: $env{"form.scantron.sub_bubblelines.n"}
9630: which are the total number of bubble, lines, the number of bubble
9631: lines for response n and number of the first bubble line for response n,
9632: and a comma separated list of numbers of bubble lines for sub-questions
9633: (for optionresponse, matchresponse, and rankresponse items), for response n.
9634:
9635:
9636: =item scantron_validate_missingbubbles() :
9637:
9638: Validates all scanlines in the selected file to not have any
9639: answers that don't have bubbles that have not been verified
9640: to be bubble free.
9641:
9642: =item scantron_process_students() :
9643:
9644: Routine that does the actual grading of the bubble sheet information.
9645:
9646: The parsed scanline hash is added to %env
9647:
9648: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9649: foreach resource , with the form data of
9650:
9651: 'submitted' =>'scantron'
9652: 'grade_target' =>'grade',
9653: 'grade_username'=> username of student
9654: 'grade_domain' => domain of student
9655: 'grade_courseid'=> of course
9656: 'grade_symb' => symb of resource to grade
9657:
9658: This triggers a grading pass. The problem grading code takes care
9659: of converting the bubbled letter information (now in %env) into a
9660: valid submission.
9661:
9662: =item scantron_upload_scantron_data() :
9663:
9664: Creates the screen for adding a new bubble sheet data file to a course.
9665:
9666: =item scantron_upload_scantron_data_save() :
9667:
9668: Adds a provided bubble information data file to the course if user
9669: has the correct privileges to do so.
9670:
9671: =item valid_file() :
9672:
9673: Validates that the requested bubble data file exists in the course.
9674:
9675: =item scantron_download_scantron_data() :
9676:
9677: Shows a list of the three internal files (original, corrected,
9678: skipped) for a specific bubble sheet data file that exists in the
9679: course.
9680:
9681: =item scantron_validate_ID() :
9682:
9683: Validates all scanlines in the selected file to not have any
9684: invalid or underspecified student/employee IDs
9685:
9686: =item navmap_errormsg() :
9687:
9688: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9689: Should be called whenever the request to instantiate a navmap object fails.
