5703: =head1 Bubble sheet grading routines
5704:
5705: For this documentation:
5706:
5707: 'scanline' refers to the full line of characters
5708: from the file that we are parsing that represents one entire sheet
5709:
5710: 'bubble line' refers to the data
5711: representing the line of bubbles that are on the physical bubblesheet
5712:
5713:
5714: The overall process is that a scanned in bubblesheet data is uploaded
5715: into a course. When a user wants to grade, they select a
5716: sequence/folder of resources, a file of bubblesheet info, and pick
5717: one of the predefined configurations for what each scanline looks
5718: like.
5719:
5720: Next each scanline is checked for any errors of either 'missing
5721: bubbles' (it's an error because it may have been mis-scanned
5722: because too light bubbling), 'double bubble' (each bubble line should
5723: have no more than one letter picked), invalid or duplicated CODE,
5724: invalid student/employee ID
5725:
5726: If the CODE option is used that determines the randomization of the
5727: homework problems, either way the student/employee ID is looked up into a
5728: username:domain.
5729:
5730: During the validation phase the instructor can choose to skip scanlines.
5731:
5732: After the validation phase, there are now 3 bubblesheet files
5733:
5734: scantron_original_filename (unmodified original file)
5735: scantron_corrected_filename (file where the corrected information has replaced the original information)
5736: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5737:
5738: Also there is a separate hash nohist_scantrondata that contains extra
5739: correction information that isn't representable in the bubblesheet
5740: file (see &scantron_getfile() for more information)
5741:
5742: After all scanlines are either valid, marked as valid or skipped, then
5743: foreach line foreach problem in the picked sequence, an ssi request is
5744: made that simulates a user submitting their selected letter(s) against
5745: the homework problem.

11054: =head1 NAME
11055:
11056: Apache::grades
11057:
11058: =head1 SYNOPSIS
11059:
11060: Handles the viewing of grades.
11061:
11062: This is part of the LearningOnline Network with CAPA project
11063: described at http://www.lon-capa.org.
11064:
11065: =head1 OVERVIEW
11066:
11067: Do an ssi with retries:
11068: While I'd love to factor out this with the vesrion in lonprintout,
11069: 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
11070: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11071:
11072: At least the logic that drives this has been pulled out into loncommon.
11073:
11074:
11075:
11076: ssi_with_retries - Does the server side include of a resource.
11077: if the ssi call returns an error we'll retry it up to
11078: the number of times requested by the caller.
11079: If we still have a problem, no text is appended to the
11080: output and we set some global variables.
11081: to indicate to the caller an SSI error occurred.
11082: All of this is supposed to deal with the issues described
11083: in LON-CAPA BZ 5631 see:
11084: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11085: by informing the user that this happened.
11086:
11087: Parameters:
11088: resource - The resource to include. This is passed directly, without
11089: interpretation to lonnet::ssi.
11090: form - The form hash parameters that guide the interpretation of the resource
11091:
11092: retries - Number of retries allowed before giving up completely.
11093: Returns:
11094: On success, returns the rendered resource identified by the resource parameter.
11095: Side Effects:
11096: The following global variables can be set:
11097: ssi_error - If an unrecoverable error occurred this becomes true.
11098: It is up to the caller to initialize this to false
11099: if desired.
11100: ssi_error_resource - If an unrecoverable error occurred, this is the value
11101: of the resource that could not be rendered by the ssi
11102: call.
11103: ssi_error_message - The error string fetched from the ssi response
11104: in the event of an error.

11116:
11117: Builds the interface screen to interact with the operator to fix a
11118: specific error condition in a specific scanline
11119:
11120: Arguments:
11121: $r - Apache request object
11122: $i - number of the current scanline
11123: $scan_record - hash ref as returned from &scantron_parse_scanline()
11124: $scan_config - hash ref as returned from &Apache::lonnet::get_scantron_config()
11125: $line - full contents of the current scanline
11126: $error - error condition, valid values are
11127: 'incorrectCODE', 'duplicateCODE',
11128: 'doublebubble', 'missingbubble',
11129: 'duplicateID', 'incorrectID'
11130: $arg - extra information needed
11131: For errors:
11132: - duplicateID - paper number that this studentID was seen before on
11133: - duplicateCODE - array ref of the paper numbers this CODE was
11134: seen on before
11135: - incorrectCODE - current incorrect CODE
11136: - doublebubble - array ref of the bubble lines that have double
11137: bubble errors
11138: - missingbubble - array ref of the bubble lines that have missing
11139: bubble errors
11140:
11141: $randomorder - True if exam folder has randomorder set
11142: $randompick - True if exam folder has randompick set
11143: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
11144: for current line to question number used for same question
11145: in "Master Seqence" (as seen by Course Coordinator).
11146: $startline - Reference to hash where key is question number (0 is first)
11147: and value is number of first bubble line for current student
11148: or code-based randompick and/or randomorder.
11149:
11150:
11151: =item scantron_get_maxbubble() :
11152:
11153: Arguments:
11154: $nav_error - Reference to scalar which is a flag to indicate a
11155: failure to retrieve a navmap object.
11156: if $nav_error is set to 1 by scantron_get_maxbubble(), the
11157: calling routine should trap the error condition and display the warning
11158: found in &navmap_errormsg().
11159:
11160: $scantron_config - Reference to bubblesheet format configuration hash.
11161:
11162: Returns the maximum number of bubble lines that are expected to
11163: occur. Does this by walking the selected sequence rendering the
11164: resource and then checking &Apache::lonxml::get_problem_counter()
11165: for what the current value of the problem counter is.
11166:
11167: Caches the results to $env{'form.scantron_maxbubble'},
11168: $env{'form.scantron.bubble_lines.n'},
11169: $env{'form.scantron.first_bubble_line.n'} and
11170: $env{"form.scantron.sub_bubblelines.n"}
11171: which are the total number of bubble lines, the number of bubble
11172: lines for response n and number of the first bubble line for response n,
11173: and a comma separated list of numbers of bubble lines for sub-questions
11174: (for optionresponse, matchresponse, and rankresponse items), for response n.
11175:
11176:
11177: =item scantron_validate_missingbubbles() :
11178:
11179: Validates all scanlines in the selected file to not have any
11180: answers that don't have bubbles that have not been verified
11181: to be bubble free.
11182:
11183: =item scantron_process_students() :
11184:
11185: Routine that does the actual grading of the bubblesheet information.
11186:
11187: The parsed scanline hash is added to %env
11188:
11189: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
11190: foreach resource , with the form data of
11191:
11192: 'submitted' =>'scantron'
11193: 'grade_target' =>'grade',
11194: 'grade_username'=> username of student
11195: 'grade_domain' => domain of student
11196: 'grade_courseid'=> of course
11197: 'grade_symb' => symb of resource to grade
11198:
11199: This triggers a grading pass. The problem grading code takes care
11200: of converting the bubbled letter information (now in %env) into a
11201: valid submission.
11202:
11203: =item scantron_upload_scantron_data() :

11216: =item scantron_download_scantron_data() :
11217:
11218: Shows a list of the three internal files (original, corrected,
11219: skipped) for a specific bubblesheet data file that exists in the
11220: course.
11221:
11222: =item scantron_validate_ID() :
11223:
11224: Validates all scanlines in the selected file to not have any
11225: invalid or underspecified student/employee IDs
11226:
11227: =item navmap_errormsg() :
11228:
11229: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
