5549: =head1 Bubble sheet grading routines
5550:
5551: For this documentation:
5552:
5553: 'scanline' refers to the full line of characters
5554: from the file that we are parsing that represents one entire sheet
5555:
5556: 'bubble line' refers to the data
5557: representing the line of bubbles that are on the physical bubblesheet
5558:
5559:
5560: The overall process is that a scanned in bubblesheet data is uploaded
5561: into a course. When a user wants to grade, they select a
5562: sequence/folder of resources, a file of bubblesheet info, and pick
5563: one of the predefined configurations for what each scanline looks
5564: like.
5565:
5566: Next each scanline is checked for any errors of either 'missing
5567: bubbles' (it's an error because it may have been mis-scanned
5568: because too light bubbling), 'double bubble' (each bubble line should
5569: have no more than one letter picked), invalid or duplicated CODE,
5570: invalid student/employee ID
5571:
5572: If the CODE option is used that determines the randomization of the
5573: homework problems, either way the student/employee ID is looked up into a
5574: username:domain.
5575:
5576: During the validation phase the instructor can choose to skip scanlines.
5577:
5578: After the validation phase, there are now 3 bubblesheet files
5579:
5580: scantron_original_filename (unmodified original file)
5581: scantron_corrected_filename (file where the corrected information has replaced the original information)
5582: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5583:
5584: Also there is a separate hash nohist_scantrondata that contains extra
5585: correction information that isn't representable in the bubblesheet
5586: file (see &scantron_getfile() for more information)
5587:
5588: After all scanlines are either valid, marked as valid or skipped, then
5589: foreach line foreach problem in the picked sequence, an ssi request is
5590: made that simulates a user submitting their selected letter(s) against
5591: the homework problem.

10954: =head1 NAME
10955:
10956: Apache::grades
10957:
10958: =head1 SYNOPSIS
10959:
10960: Handles the viewing of grades.
10961:
10962: This is part of the LearningOnline Network with CAPA project
10963: described at http://www.lon-capa.org.
10964:
10965: =head1 OVERVIEW
10966:
10967: Do an ssi with retries:
10968: While I'd love to factor out this with the vesrion in lonprintout,
10969: 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
10970: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10971:
10972: At least the logic that drives this has been pulled out into loncommon.
10973:
10974:
10975:
10976: ssi_with_retries - Does the server side include of a resource.
10977: if the ssi call returns an error we'll retry it up to
10978: the number of times requested by the caller.
10979: If we still have a problem, no text is appended to the
10980: output and we set some global variables.
10981: to indicate to the caller an SSI error occurred.
10982: All of this is supposed to deal with the issues described
10983: in LON-CAPA BZ 5631 see:
10984: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10985: by informing the user that this happened.
10986:
10987: Parameters:
10988: resource - The resource to include. This is passed directly, without
10989: interpretation to lonnet::ssi.
10990: form - The form hash parameters that guide the interpretation of the resource
10991:
10992: retries - Number of retries allowed before giving up completely.
10993: Returns:
10994: On success, returns the rendered resource identified by the resource parameter.
10995: Side Effects:
10996: The following global variables can be set:
10997: ssi_error - If an unrecoverable error occurred this becomes true.
10998: It is up to the caller to initialize this to false
10999: if desired.
11000: ssi_error_resource - If an unrecoverable error occurred, this is the value
11001: of the resource that could not be rendered by the ssi
11002: call.
11003: ssi_error_message - The error string fetched from the ssi response
11004: in the event of an error.

11014:
11015: =item scantron_get_correction() :
11016:
11017: Builds the interface screen to interact with the operator to fix a
11018: specific error condition in a specific scanline
11019:
11020: Arguments:
11021: $r - Apache request object
11022: $i - number of the current scanline
11023: $scan_record - hash ref as returned from &scantron_parse_scanline()
11024: $scan_config - hash ref as returned from &get_scantron_config()
11025: $line - full contents of the current scanline
11026: $error - error condition, valid values are
11027: 'incorrectCODE', 'duplicateCODE',
11028: 'doublebubble', 'missingbubble',
11029: 'duplicateID', 'incorrectID'
11030: $arg - extra information needed
11031: For errors:
11032: - duplicateID - paper number that this studentID was seen before on
11033: - duplicateCODE - array ref of the paper numbers this CODE was
11034: seen on before
11035: - incorrectCODE - current incorrect CODE
11036: - doublebubble - array ref of the bubble lines that have double
11037: bubble errors
11038: - missingbubble - array ref of the bubble lines that have missing
11039: bubble errors
11040:
11041: $randomorder - True if exam folder has randomorder set
11042: $randompick - True if exam folder has randompick set
11043: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
11044: for current line to question number used for same question
11045: in "Master Seqence" (as seen by Course Coordinator).
11046: $startline - Reference to hash where key is question number (0 is first)
11047: and value is number of first bubble line for current student
11048: or code-based randompick and/or randomorder.
11049:
11050:
11051: =item scantron_get_maxbubble() :
11052:
11053: Arguments:
11054: $nav_error - Reference to scalar which is a flag to indicate a
11055: failure to retrieve a navmap object.
11056: if $nav_error is set to 1 by scantron_get_maxbubble(), the
11057: calling routine should trap the error condition and display the warning
11058: found in &navmap_errormsg().
11059:
11060: $scantron_config - Reference to bubblesheet format configuration hash.
11061:
11062: Returns the maximum number of bubble lines that are expected to
11063: occur. Does this by walking the selected sequence rendering the
11064: resource and then checking &Apache::lonxml::get_problem_counter()
11065: for what the current value of the problem counter is.
11066:
11067: Caches the results to $env{'form.scantron_maxbubble'},
11068: $env{'form.scantron.bubble_lines.n'},
11069: $env{'form.scantron.first_bubble_line.n'} and
11070: $env{"form.scantron.sub_bubblelines.n"}
11071: which are the total number of bubble lines, the number of bubble
11072: lines for response n and number of the first bubble line for response n,
11073: and a comma separated list of numbers of bubble lines for sub-questions
11074: (for optionresponse, matchresponse, and rankresponse items), for response n.
11075:
11076:
11077: =item scantron_validate_missingbubbles() :
11078:
11079: Validates all scanlines in the selected file to not have any
11080: answers that don't have bubbles that have not been verified
11081: to be bubble free.
11082:
11083: =item scantron_process_students() :
11084:
11085: Routine that does the actual grading of the bubblesheet information.
11086:
11087: The parsed scanline hash is added to %env
11088:
11089: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
11090: foreach resource , with the form data of
11091:
11092: 'submitted' =>'scantron'
11093: 'grade_target' =>'grade',
11094: 'grade_username'=> username of student
11095: 'grade_domain' => domain of student
11096: 'grade_courseid'=> of course
11097: 'grade_symb' => symb of resource to grade
11098:
11099: This triggers a grading pass. The problem grading code takes care
11100: of converting the bubbled letter information (now in %env) into a
11101: valid submission.
11102:
11103: =item scantron_upload_scantron_data() :

11118: Shows a list of the three internal files (original, corrected,
11119: skipped) for a specific bubblesheet data file that exists in the
11120: course.
11121:
11122: =item scantron_validate_ID() :
11123:
11124: Validates all scanlines in the selected file to not have any
11125: invalid or underspecified student/employee IDs
11126:
11127: =item navmap_errormsg() :
11128:
11129: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
