5692: =head1 Bubble sheet grading routines
5693:
5694: For this documentation:
5695:
5696: 'scanline' refers to the full line of characters
5697: from the file that we are parsing that represents one entire sheet
5698:
5699: 'bubble line' refers to the data
5700: representing the line of bubbles that are on the physical bubblesheet
5701:
5702:
5703: The overall process is that a scanned in bubblesheet data is uploaded
5704: into a course. When a user wants to grade, they select a
5705: sequence/folder of resources, a file of bubblesheet info, and pick
5706: one of the predefined configurations for what each scanline looks
5707: like.
5708:
5709: Next each scanline is checked for any errors of either 'missing
5710: bubbles' (it's an error because it may have been mis-scanned
5711: because too light bubbling), 'double bubble' (each bubble line should
5712: have no more than one letter picked), invalid or duplicated CODE,
5713: invalid student/employee ID
5714:
5715: If the CODE option is used that determines the randomization of the
5716: homework problems, either way the student/employee ID is looked up into a
5717: username:domain.
5718:
5719: During the validation phase the instructor can choose to skip scanlines.
5720:
5721: After the validation phase, there are now 3 bubblesheet files
5722:
5723: scantron_original_filename (unmodified original file)
5724: scantron_corrected_filename (file where the corrected information has replaced the original information)
5725: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5726:
5727: Also there is a separate hash nohist_scantrondata that contains extra
5728: correction information that isn't representable in the bubblesheet
5729: file (see &scantron_getfile() for more information)
5730:
5731: After all scanlines are either valid, marked as valid or skipped, then
5732: foreach line foreach problem in the picked sequence, an ssi request is
5733: made that simulates a user submitting their selected letter(s) against
5734: the homework problem.

11039: =head1 NAME
11040:
11041: Apache::grades
11042:
11043: =head1 SYNOPSIS
11044:
11045: Handles the viewing of grades.
11046:
11047: This is part of the LearningOnline Network with CAPA project
11048: described at http://www.lon-capa.org.
11049:
11050: =head1 OVERVIEW
11051:
11052: Do an ssi with retries:
11053: While I'd love to factor out this with the vesrion in lonprintout,
11054: 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
11055: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11056:
11057: At least the logic that drives this has been pulled out into loncommon.
11058:
11059:
11060:
11061: ssi_with_retries - Does the server side include of a resource.
11062: if the ssi call returns an error we'll retry it up to
11063: the number of times requested by the caller.
11064: If we still have a problem, no text is appended to the
11065: output and we set some global variables.
11066: to indicate to the caller an SSI error occurred.
11067: All of this is supposed to deal with the issues described
11068: in LON-CAPA BZ 5631 see:
11069: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11070: by informing the user that this happened.
11071:
11072: Parameters:
11073: resource - The resource to include. This is passed directly, without
11074: interpretation to lonnet::ssi.
11075: form - The form hash parameters that guide the interpretation of the resource
11076:
11077: retries - Number of retries allowed before giving up completely.
11078: Returns:
11079: On success, returns the rendered resource identified by the resource parameter.
11080: Side Effects:
11081: The following global variables can be set:
11082: ssi_error - If an unrecoverable error occurred this becomes true.
11083: It is up to the caller to initialize this to false
11084: if desired.
11085: ssi_error_resource - If an unrecoverable error occurred, this is the value
11086: of the resource that could not be rendered by the ssi
11087: call.
11088: ssi_error_message - The error string fetched from the ssi response
11089: in the event of an error.

11100: =item scantron_get_correction() :
11101:
11102: Builds the interface screen to interact with the operator to fix a
11103: specific error condition in a specific scanline
11104:
11105: Arguments:
11106: $r - Apache request object
11107: $i - number of the current scanline
11108: $scan_record - hash ref as returned from &scantron_parse_scanline()
11109: $scan_config - hash ref as returned from &Apache::lonnet::get_scantron_config()
11110: $line - full contents of the current scanline
11111: $error - error condition, valid values are
11112: 'incorrectCODE', 'duplicateCODE',
11113: 'doublebubble', 'missingbubble',
11114: 'duplicateID', 'incorrectID'
11115: $arg - extra information needed
11116: For errors:
11117: - duplicateID - paper number that this studentID was seen before on
11118: - duplicateCODE - array ref of the paper numbers this CODE was
11119: seen on before
11120: - incorrectCODE - current incorrect CODE
11121: - doublebubble - array ref of the bubble lines that have double
11122: bubble errors
11123: - missingbubble - array ref of the bubble lines that have missing
11124: bubble errors
11125:
11126: $randomorder - True if exam folder has randomorder set
11127: $randompick - True if exam folder has randompick set
11128: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
11129: for current line to question number used for same question
11130: in "Master Seqence" (as seen by Course Coordinator).
11131: $startline - Reference to hash where key is question number (0 is first)
11132: and value is number of first bubble line for current student
11133: or code-based randompick and/or randomorder.
11134:
11135:
11136: =item scantron_get_maxbubble() :
11137:
11138: Arguments:
11139: $nav_error - Reference to scalar which is a flag to indicate a
11140: failure to retrieve a navmap object.
11141: if $nav_error is set to 1 by scantron_get_maxbubble(), the
11142: calling routine should trap the error condition and display the warning
11143: found in &navmap_errormsg().
11144:
11145: $scantron_config - Reference to bubblesheet format configuration hash.
11146:
11147: Returns the maximum number of bubble lines that are expected to
11148: occur. Does this by walking the selected sequence rendering the
11149: resource and then checking &Apache::lonxml::get_problem_counter()
11150: for what the current value of the problem counter is.
11151:
11152: Caches the results to $env{'form.scantron_maxbubble'},
11153: $env{'form.scantron.bubble_lines.n'},
11154: $env{'form.scantron.first_bubble_line.n'} and
11155: $env{"form.scantron.sub_bubblelines.n"}
11156: which are the total number of bubble lines, the number of bubble
11157: lines for response n and number of the first bubble line for response n,
11158: and a comma separated list of numbers of bubble lines for sub-questions
11159: (for optionresponse, matchresponse, and rankresponse items), for response n.
11160:
11161:
11162: =item scantron_validate_missingbubbles() :
11163:
11164: Validates all scanlines in the selected file to not have any
11165: answers that don't have bubbles that have not been verified
11166: to be bubble free.
11167:
11168: =item scantron_process_students() :
11169:
11170: Routine that does the actual grading of the bubblesheet information.
11171:
11172: The parsed scanline hash is added to %env
11173:
11174: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
11175: foreach resource , with the form data of
11176:
11177: 'submitted' =>'scantron'
11178: 'grade_target' =>'grade',
11179: 'grade_username'=> username of student
11180: 'grade_domain' => domain of student
11181: 'grade_courseid'=> of course
11182: 'grade_symb' => symb of resource to grade
11183:
11184: This triggers a grading pass. The problem grading code takes care
11185: of converting the bubbled letter information (now in %env) into a
11186: valid submission.
11187:
11188: =item scantron_upload_scantron_data() :
11189:

11201: =item scantron_download_scantron_data() :
11202:
11203: Shows a list of the three internal files (original, corrected,
11204: skipped) for a specific bubblesheet data file that exists in the
11205: course.
11206:
11207: =item scantron_validate_ID() :
11208:
11209: Validates all scanlines in the selected file to not have any
11210: invalid or underspecified student/employee IDs
11211:
11212: =item navmap_errormsg() :
