4999: =head1 Bubble sheet grading routines
5000:
5001: For this documentation:
5002:
5003: 'scanline' refers to the full line of characters
5004: from the file that we are parsing that represents one entire sheet
5005:
5006: 'bubble line' refers to the data
5007: representing the line of bubbles that are on the physical bubblesheet
5008:
5009:
5010: The overall process is that a scanned in bubblesheet data is uploaded
5011: into a course. When a user wants to grade, they select a
5012: sequence/folder of resources, a file of bubblesheet info, and pick
5013: one of the predefined configurations for what each scanline looks
5014: like.
5015:
5016: Next each scanline is checked for any errors of either 'missing
5017: bubbles' (it's an error because it may have been mis-scanned
5018: because too light bubbling), 'double bubble' (each bubble line should
5019: have no more that one letter picked), invalid or duplicated CODE,
5020: invalid student/employee ID
5021:
5022: If the CODE option is used that determines the randomization of the
5023: homework problems, either way the student/employee ID is looked up into a
5024: username:domain.
5025:
5026: During the validation phase the instructor can choose to skip scanlines.
5027:
5028: After the validation phase, there are now 3 bubblesheet files
5029:
5030: scantron_original_filename (unmodified original file)
5031: scantron_corrected_filename (file where the corrected information has replaced the original information)
5032: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5033:
5034: Also there is a separate hash nohist_scantrondata that contains extra
5035: correction information that isn't representable in the bubblesheet
5036: file (see &scantron_getfile() for more information)
5037:
5038: After all scanlines are either valid, marked as valid or skipped, then
5039: foreach line foreach problem in the picked sequence, an ssi request is
5040: made that simulates a user submitting their selected letter(s) against
5041: the homework problem.

9775: =head1 NAME
9776:
9777: Apache::grades
9778:
9779: =head1 SYNOPSIS
9780:
9781: Handles the viewing of grades.
9782:
9783: This is part of the LearningOnline Network with CAPA project
9784: described at http://www.lon-capa.org.
9785:
9786: =head1 OVERVIEW
9787:
9788: Do an ssi with retries:
9789: While I'd love to factor out this with the vesrion in lonprintout,
9790: 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
9791: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9792:
9793: At least the logic that drives this has been pulled out into loncommon.
9794:
9795:
9796:
9797: ssi_with_retries - Does the server side include of a resource.
9798: if the ssi call returns an error we'll retry it up to
9799: the number of times requested by the caller.
9800: If we still have a proble, no text is appended to the
9801: output and we set some global variables.
9802: to indicate to the caller an SSI error occurred.
9803: All of this is supposed to deal with the issues described
9804: in LonCAPA BZ 5631 see:
9805: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9806: by informing the user that this happened.
9807:
9808: Parameters:
9809: resource - The resource to include. This is passed directly, without
9810: interpretation to lonnet::ssi.
9811: form - The form hash parameters that guide the interpretation of the resource
9812:
9813: retries - Number of retries allowed before giving up completely.
9814: Returns:
9815: On success, returns the rendered resource identified by the resource parameter.
9816: Side Effects:
9817: The following global variables can be set:
9818: ssi_error - If an unrecoverable error occurred this becomes true.
9819: It is up to the caller to initialize this to false
9820: if desired.
9821: ssi_error_resource - If an unrecoverable error occurred, this is the value
9822: of the resource that could not be rendered by the ssi
9823: call.
9824: ssi_error_message - The error string fetched from the ssi response
9825: in the event of an error.

9836: =item scantron_get_correction() :
9837:
9838: Builds the interface screen to interact with the operator to fix a
9839: specific error condition in a specific scanline
9840:
9841: Arguments:
9842: $r - Apache request object
9843: $i - number of the current scanline
9844: $scan_record - hash ref as returned from &scantron_parse_scanline()
9845: $scan_config - hash ref as returned from &get_scantron_config()
9846: $line - full contents of the current scanline
9847: $error - error condition, valid values are
9848: 'incorrectCODE', 'duplicateCODE',
9849: 'doublebubble', 'missingbubble',
9850: 'duplicateID', 'incorrectID'
9851: $arg - extra information needed
9852: For errors:
9853: - duplicateID - paper number that this studentID was seen before on
9854: - duplicateCODE - array ref of the paper numbers this CODE was
9855: seen on before
9856: - incorrectCODE - current incorrect CODE
9857: - doublebubble - array ref of the bubble lines that have double
9858: bubble errors
9859: - missingbubble - array ref of the bubble lines that have missing
9860: bubble errors
9861:
9862: =item scantron_get_maxbubble() :
9863:
9864: Arguments:
9865: $nav_error - Reference to scalar which is a flag to indicate a
9866: failure to retrieve a navmap object.
9867: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9868: calling routine should trap the error condition and display the warning
9869: found in &navmap_errormsg().
9870:
9871: $scantron_config - Reference to bubblesheet format configuration hash.
9872:
9873: Returns the maximum number of bubble lines that are expected to
9874: occur. Does this by walking the selected sequence rendering the
9875: resource and then checking &Apache::lonxml::get_problem_counter()
9876: for what the current value of the problem counter is.
9877:
9878: Caches the results to $env{'form.scantron_maxbubble'},
9879: $env{'form.scantron.bubble_lines.n'},
9880: $env{'form.scantron.first_bubble_line.n'} and
9881: $env{"form.scantron.sub_bubblelines.n"}
9882: which are the total number of bubble, lines, the number of bubble
9883: lines for response n and number of the first bubble line for response n,
9884: and a comma separated list of numbers of bubble lines for sub-questions
9885: (for optionresponse, matchresponse, and rankresponse items), for response n.
9886:
9887:
9888: =item scantron_validate_missingbubbles() :
9889:
9890: Validates all scanlines in the selected file to not have any
9891: answers that don't have bubbles that have not been verified
9892: to be bubble free.
9893:
9894: =item scantron_process_students() :
9895:
9896: Routine that does the actual grading of the bubblesheet information.
9897:
9898: The parsed scanline hash is added to %env
9899:
9900: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9901: foreach resource , with the form data of
9902:
9903: 'submitted' =>'scantron'
9904: 'grade_target' =>'grade',
9905: 'grade_username'=> username of student
9906: 'grade_domain' => domain of student
9907: 'grade_courseid'=> of course
9908: 'grade_symb' => symb of resource to grade
9909:
9910: This triggers a grading pass. The problem grading code takes care
9911: of converting the bubbled letter information (now in %env) into a
9912: valid submission.
9913:
9914: =item scantron_upload_scantron_data() :
9915:

9919:
9920: Adds a provided bubble information data file to the course if user
9921: has the correct privileges to do so.
9922:
9923: =item valid_file() :
9924:
9925: Validates that the requested bubble data file exists in the course.
9926:
9927: =item scantron_download_scantron_data() :
9928:
9929: Shows a list of the three internal files (original, corrected,
9930: skipped) for a specific bubblesheet data file that exists in the
9931: course.
9932:
9933: =item scantron_validate_ID() :
9934:
9935: Validates all scanlines in the selected file to not have any
9936: invalid or underspecified student/employee IDs
9937:
9938: =item navmap_errormsg() :
9939:
9940: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9941: Should be called whenever the request to instantiate a navmap object fails.
