4837: =head1 Bubble sheet grading routines
4838:
4839: For this documentation:
4840:
4841: 'scanline' refers to the full line of characters
4842: from the file that we are parsing that represents one entire sheet
4843:
4844: 'bubble line' refers to the data
4845: representing the line of bubbles that are on the physical bubblesheet
4846:
4847:
4848: The overall process is that a scanned in bubblesheet data is uploaded
4849: into a course. When a user wants to grade, they select a
4850: sequence/folder of resources, a file of bubblesheet info, and pick
4851: one of the predefined configurations for what each scanline looks
4852: like.
4853:
4854: Next each scanline is checked for any errors of either 'missing
4855: bubbles' (it's an error because it may have been mis-scanned
4856: because too light bubbling), 'double bubble' (each bubble line should
4857: have no more that one letter picked), invalid or duplicated CODE,
4858: invalid student/employee ID
4859:
4860: If the CODE option is used that determines the randomization of the
4861: homework problems, either way the student/employee ID is looked up into a
4862: username:domain.
4863:
4864: During the validation phase the instructor can choose to skip scanlines.
4865:
4866: After the validation phase, there are now 3 bubblesheet files
4867:
4868: scantron_original_filename (unmodified original file)
4869: scantron_corrected_filename (file where the corrected information has replaced the original information)
4870: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4871:
4872: Also there is a separate hash nohist_scantrondata that contains extra
4873: correction information that isn't representable in the bubblesheet
4874: file (see &scantron_getfile() for more information)
4875:
4876: After all scanlines are either valid, marked as valid or skipped, then
4877: foreach line foreach problem in the picked sequence, an ssi request is
4878: made that simulates a user submitting their selected letter(s) against
4879: the homework problem.

9601: =head1 NAME
9602:
9603: Apache::grades
9604:
9605: =head1 SYNOPSIS
9606:
9607: Handles the viewing of grades.
9608:
9609: This is part of the LearningOnline Network with CAPA project
9610: described at http://www.lon-capa.org.
9611:
9612: =head1 OVERVIEW
9613:
9614: Do an ssi with retries:
9615: While I'd love to factor out this with the vesrion in lonprintout,
9616: 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
9617: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9618:
9619: At least the logic that drives this has been pulled out into loncommon.
9620:
9621:
9622:
9623: ssi_with_retries - Does the server side include of a resource.
9624: if the ssi call returns an error we'll retry it up to
9625: the number of times requested by the caller.
9626: If we still have a proble, no text is appended to the
9627: output and we set some global variables.
9628: to indicate to the caller an SSI error occurred.
9629: All of this is supposed to deal with the issues described
9630: in LonCAPA BZ 5631 see:
9631: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9632: by informing the user that this happened.
9633:
9634: Parameters:
9635: resource - The resource to include. This is passed directly, without
9636: interpretation to lonnet::ssi.
9637: form - The form hash parameters that guide the interpretation of the resource
9638:
9639: retries - Number of retries allowed before giving up completely.
9640: Returns:
9641: On success, returns the rendered resource identified by the resource parameter.
9642: Side Effects:
9643: The following global variables can be set:
9644: ssi_error - If an unrecoverable error occurred this becomes true.
9645: It is up to the caller to initialize this to false
9646: if desired.
9647: ssi_error_resource - If an unrecoverable error occurred, this is the value
9648: of the resource that could not be rendered by the ssi
9649: call.
9650: ssi_error_message - The error string fetched from the ssi response
9651: in the event of an error.

9661:
9662: =item scantron_get_correction() :
9663:
9664: Builds the interface screen to interact with the operator to fix a
9665: specific error condition in a specific scanline
9666:
9667: Arguments:
9668: $r - Apache request object
9669: $i - number of the current scanline
9670: $scan_record - hash ref as returned from &scantron_parse_scanline()
9671: $scan_config - hash ref as returned from &get_scantron_config()
9672: $line - full contents of the current scanline
9673: $error - error condition, valid values are
9674: 'incorrectCODE', 'duplicateCODE',
9675: 'doublebubble', 'missingbubble',
9676: 'duplicateID', 'incorrectID'
9677: $arg - extra information needed
9678: For errors:
9679: - duplicateID - paper number that this studentID was seen before on
9680: - duplicateCODE - array ref of the paper numbers this CODE was
9681: seen on before
9682: - incorrectCODE - current incorrect CODE
9683: - doublebubble - array ref of the bubble lines that have double
9684: bubble errors
9685: - missingbubble - array ref of the bubble lines that have missing
9686: bubble errors
9687:
9688: =item scantron_get_maxbubble() :
9689:
9690: Arguments:
9691: $nav_error - Reference to scalar which is a flag to indicate a
9692: failure to retrieve a navmap object.
9693: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9694: calling routine should trap the error condition and display the warning
9695: found in &navmap_errormsg().
9696:
9697: $scantron_config - Reference to bubblesheet format configuration hash.
9698:
9699: Returns the maximum number of bubble lines that are expected to
9700: occur. Does this by walking the selected sequence rendering the
9701: resource and then checking &Apache::lonxml::get_problem_counter()
9702: for what the current value of the problem counter is.
9703:
9704: Caches the results to $env{'form.scantron_maxbubble'},
9705: $env{'form.scantron.bubble_lines.n'},
9706: $env{'form.scantron.first_bubble_line.n'} and
9707: $env{"form.scantron.sub_bubblelines.n"}
9708: which are the total number of bubble, lines, the number of bubble
9709: lines for response n and number of the first bubble line for response n,
9710: and a comma separated list of numbers of bubble lines for sub-questions
9711: (for optionresponse, matchresponse, and rankresponse items), for response n.
9712:
9713:
9714: =item scantron_validate_missingbubbles() :
9715:
9716: Validates all scanlines in the selected file to not have any
9717: answers that don't have bubbles that have not been verified
9718: to be bubble free.
9719:
9720: =item scantron_process_students() :
9721:
9722: Routine that does the actual grading of the bubblesheet information.
9723:
9724: The parsed scanline hash is added to %env
9725:
9726: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9727: foreach resource , with the form data of
9728:
9729: 'submitted' =>'scantron'
9730: 'grade_target' =>'grade',
9731: 'grade_username'=> username of student
9732: 'grade_domain' => domain of student
9733: 'grade_courseid'=> of course
9734: 'grade_symb' => symb of resource to grade
9735:
9736: This triggers a grading pass. The problem grading code takes care
9737: of converting the bubbled letter information (now in %env) into a
9738: valid submission.
9739:
9740: =item scantron_upload_scantron_data() :
9741:
9742: Creates the screen for adding a new bubblesheet data file to a course.
9743:
9744: =item scantron_upload_scantron_data_save() :
9745:
9746: Adds a provided bubble information data file to the course if user
9747: has the correct privileges to do so.
9748:
9749: =item valid_file() :
9750:
9751: Validates that the requested bubble data file exists in the course.
9752:
9753: =item scantron_download_scantron_data() :
9754:
9755: Shows a list of the three internal files (original, corrected,
9756: skipped) for a specific bubblesheet data file that exists in the
9757: course.
9758:
9759: =item scantron_validate_ID() :
9760:
9761: Validates all scanlines in the selected file to not have any
9762: invalid or underspecified student/employee IDs
9763:
9764: =item navmap_errormsg() :
9765:
9766: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9767: Should be called whenever the request to instantiate a navmap object fails.
