1.424 albertel 4990: For this documentation:
4991:
4992: 'scanline' refers to the full line of characters
4993: from the file that we are parsing that represents one entire sheet
4994:
4995: 'bubble line' refers to the data
1.596.2.6 raeburn 4996: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 4997:
4998:
1.596.2.6 raeburn 4999: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5000: into a course. When a user wants to grade, they select a
1.596.2.6 raeburn 5001: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5002: one of the predefined configurations for what each scanline looks
5003: like.
5004:
5005: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5006: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5007: because too light bubbling), 'double bubble' (each bubble line should
5008: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 5009: invalid student/employee ID
1.424 albertel 5010:
5011: If the CODE option is used that determines the randomization of the
1.556 weissno 5012: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5013: username:domain.
5014:
5015: During the validation phase the instructor can choose to skip scanlines.
5016:
1.596.2.6 raeburn 5017: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5018:
5019: scantron_original_filename (unmodified original file)
5020: scantron_corrected_filename (file where the corrected information has replaced the original information)
5021: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5022:
5023: Also there is a separate hash nohist_scantrondata that contains extra
1.596.2.6 raeburn 5024: correction information that isn't representable in the bubblesheet
1.424 albertel 5025: file (see &scantron_getfile() for more information)
5026:
5027: After all scanlines are either valid, marked as valid or skipped, then
5028: foreach line foreach problem in the picked sequence, an ssi request is
5029: made that simulates a user submitting their selected letter(s) against
5030: the homework problem.

9673: =head1 NAME
9674:
9675: Apache::grades
9676:
9677: =head1 SYNOPSIS
9678:
9679: Handles the viewing of grades.
9680:
9681: This is part of the LearningOnline Network with CAPA project
9682: described at http://www.lon-capa.org.
9683:
9684: =head1 OVERVIEW
9685:
9686: Do an ssi with retries:
9687: While I'd love to factor out this with the vesrion in lonprintout,
9688: 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
9689: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9690:
9691: At least the logic that drives this has been pulled out into loncommon.
9692:
9693:
9694:
9695: ssi_with_retries - Does the server side include of a resource.
9696: if the ssi call returns an error we'll retry it up to
9697: the number of times requested by the caller.
9698: If we still have a proble, no text is appended to the
9699: output and we set some global variables.
9700: to indicate to the caller an SSI error occurred.
9701: All of this is supposed to deal with the issues described
9702: in LonCAPA BZ 5631 see:
9703: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9704: by informing the user that this happened.
9705:
9706: Parameters:
9707: resource - The resource to include. This is passed directly, without
9708: interpretation to lonnet::ssi.
9709: form - The form hash parameters that guide the interpretation of the resource
9710:
9711: retries - Number of retries allowed before giving up completely.
9712: Returns:
9713: On success, returns the rendered resource identified by the resource parameter.
9714: Side Effects:
9715: The following global variables can be set:
9716: ssi_error - If an unrecoverable error occurred this becomes true.
9717: It is up to the caller to initialize this to false
9718: if desired.
9719: ssi_error_resource - If an unrecoverable error occurred, this is the value
9720: of the resource that could not be rendered by the ssi
9721: call.
9722: ssi_error_message - The error string fetched from the ssi response
9723: in the event of an error.

9734: =item scantron_get_correction() :
9735:
9736: Builds the interface screen to interact with the operator to fix a
9737: specific error condition in a specific scanline
9738:
9739: Arguments:
9740: $r - Apache request object
9741: $i - number of the current scanline
9742: $scan_record - hash ref as returned from &scantron_parse_scanline()
9743: $scan_config - hash ref as returned from &get_scantron_config()
9744: $line - full contents of the current scanline
9745: $error - error condition, valid values are
9746: 'incorrectCODE', 'duplicateCODE',
9747: 'doublebubble', 'missingbubble',
9748: 'duplicateID', 'incorrectID'
9749: $arg - extra information needed
9750: For errors:
9751: - duplicateID - paper number that this studentID was seen before on
9752: - duplicateCODE - array ref of the paper numbers this CODE was
9753: seen on before
9754: - incorrectCODE - current incorrect CODE
9755: - doublebubble - array ref of the bubble lines that have double
9756: bubble errors
9757: - missingbubble - array ref of the bubble lines that have missing
9758: bubble errors
9759:
9760: =item scantron_get_maxbubble() :
9761:
1.582 raeburn 9762: Arguments:
9763: $nav_error - Reference to scalar which is a flag to indicate a
9764: failure to retrieve a navmap object.
9765: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9766: calling routine should trap the error condition and display the warning
9767: found in &navmap_errormsg().
9768:
1.531 jms 9769: Returns the maximum number of bubble lines that are expected to
9770: occur. Does this by walking the selected sequence rendering the
9771: resource and then checking &Apache::lonxml::get_problem_counter()
9772: for what the current value of the problem counter is.
9773:
9774: Caches the results to $env{'form.scantron_maxbubble'},
9775: $env{'form.scantron.bubble_lines.n'},
9776: $env{'form.scantron.first_bubble_line.n'} and
9777: $env{"form.scantron.sub_bubblelines.n"}
9778: which are the total number of bubble, lines, the number of bubble
9779: lines for response n and number of the first bubble line for response n,
9780: and a comma separated list of numbers of bubble lines for sub-questions
9781: (for optionresponse, matchresponse, and rankresponse items), for response n.

9791:
1.596.2.6 raeburn 9792: Routine that does the actual grading of the bubblesheet information.
1.531 jms 9793:
9794: The parsed scanline hash is added to %env
9795:
9796: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9797: foreach resource , with the form data of
9798:
9799: 'submitted' =>'scantron'
9800: 'grade_target' =>'grade',
9801: 'grade_username'=> username of student
9802: 'grade_domain' => domain of student
9803: 'grade_courseid'=> of course
9804: 'grade_symb' => symb of resource to grade
9805:
9806: This triggers a grading pass. The problem grading code takes care
9807: of converting the bubbled letter information (now in %env) into a
9808: valid submission.
