5548: =head1 Bubble sheet grading routines
5549:
5550: For this documentation:
5551:
5552: 'scanline' refers to the full line of characters
5553: from the file that we are parsing that represents one entire sheet
5554:
5555: 'bubble line' refers to the data
5556: representing the line of bubbles that are on the physical bubblesheet
5557:
5558:
5559: The overall process is that a scanned in bubblesheet data is uploaded
5560: into a course. When a user wants to grade, they select a
5561: sequence/folder of resources, a file of bubblesheet info, and pick
5562: one of the predefined configurations for what each scanline looks
5563: like.
5564:
5565: Next each scanline is checked for any errors of either 'missing
5566: bubbles' (it's an error because it may have been mis-scanned
5567: because too light bubbling), 'double bubble' (each bubble line should
5568: have no more than one letter picked), invalid or duplicated CODE,
5569: invalid student/employee ID
5570:
5571: If the CODE option is used that determines the randomization of the
5572: homework problems, either way the student/employee ID is looked up into a
5573: username:domain.
5574:
5575: During the validation phase the instructor can choose to skip scanlines.
5576:
5577: After the validation phase, there are now 3 bubblesheet files
5578:
5579: scantron_original_filename (unmodified original file)
5580: scantron_corrected_filename (file where the corrected information has replaced the original information)
5581: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5582:
5583: Also there is a separate hash nohist_scantrondata that contains extra
5584: correction information that isn't representable in the bubblesheet
5585: file (see &scantron_getfile() for more information)
5586:
5587: After all scanlines are either valid, marked as valid or skipped, then
5588: foreach line foreach problem in the picked sequence, an ssi request is
5589: made that simulates a user submitting their selected letter(s) against
5590: the homework problem.

10953: =head1 NAME
10954:
10955: Apache::grades
10956:
10957: =head1 SYNOPSIS
10958:
10959: Handles the viewing of grades.
10960:
10961: This is part of the LearningOnline Network with CAPA project
10962: described at http://www.lon-capa.org.
10963:
10964: =head1 OVERVIEW
10965:
10966: Do an ssi with retries:
10967: While I'd love to factor out this with the vesrion in lonprintout,
10968: 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
10969: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10970:
10971: At least the logic that drives this has been pulled out into loncommon.
10972:
10973:
10974:
10975: ssi_with_retries - Does the server side include of a resource.
10976: if the ssi call returns an error we'll retry it up to
10977: the number of times requested by the caller.
10978: If we still have a problem, no text is appended to the
10979: output and we set some global variables.
10980: to indicate to the caller an SSI error occurred.
10981: All of this is supposed to deal with the issues described
10982: in LON-CAPA BZ 5631 see:
10983: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10984: by informing the user that this happened.
10985:
10986: Parameters:
10987: resource - The resource to include. This is passed directly, without
10988: interpretation to lonnet::ssi.
10989: form - The form hash parameters that guide the interpretation of the resource
10990:
10991: retries - Number of retries allowed before giving up completely.
10992: Returns:
10993: On success, returns the rendered resource identified by the resource parameter.
10994: Side Effects:
10995: The following global variables can be set:
10996: ssi_error - If an unrecoverable error occurred this becomes true.
10997: It is up to the caller to initialize this to false
10998: if desired.
10999: ssi_error_resource - If an unrecoverable error occurred, this is the value
11000: of the resource that could not be rendered by the ssi
11001: call.
11002: ssi_error_message - The error string fetched from the ssi response
11003: in the event of an error.

11013:
11014: =item scantron_get_correction() :
11015:
11016: Builds the interface screen to interact with the operator to fix a
11017: specific error condition in a specific scanline
11018:
11019: Arguments:
11020: $r - Apache request object
11021: $i - number of the current scanline
11022: $scan_record - hash ref as returned from &scantron_parse_scanline()
11023: $scan_config - hash ref as returned from &get_scantron_config()
11024: $line - full contents of the current scanline
11025: $error - error condition, valid values are
11026: 'incorrectCODE', 'duplicateCODE',
11027: 'doublebubble', 'missingbubble',
11028: 'duplicateID', 'incorrectID'
11029: $arg - extra information needed
11030: For errors:
11031: - duplicateID - paper number that this studentID was seen before on
11032: - duplicateCODE - array ref of the paper numbers this CODE was
11033: seen on before
11034: - incorrectCODE - current incorrect CODE
11035: - doublebubble - array ref of the bubble lines that have double
11036: bubble errors
11037: - missingbubble - array ref of the bubble lines that have missing
11038: bubble errors
11039:
11040: $randomorder - True if exam folder has randomorder set
11041: $randompick - True if exam folder has randompick set
11042: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
11043: for current line to question number used for same question
11044: in "Master Seqence" (as seen by Course Coordinator).
11045: $startline - Reference to hash where key is question number (0 is first)
11046: and value is number of first bubble line for current student
11047: or code-based randompick and/or randomorder.
11048:
11049:
11050: =item scantron_get_maxbubble() :
11051:
11052: Arguments:
11053: $nav_error - Reference to scalar which is a flag to indicate a
11054: failure to retrieve a navmap object.
11055: if $nav_error is set to 1 by scantron_get_maxbubble(), the
11056: calling routine should trap the error condition and display the warning
11057: found in &navmap_errormsg().
11058:
11059: $scantron_config - Reference to bubblesheet format configuration hash.
11060:
11061: Returns the maximum number of bubble lines that are expected to
11062: occur. Does this by walking the selected sequence rendering the
11063: resource and then checking &Apache::lonxml::get_problem_counter()
11064: for what the current value of the problem counter is.
11065:
11066: Caches the results to $env{'form.scantron_maxbubble'},
11067: $env{'form.scantron.bubble_lines.n'},
11068: $env{'form.scantron.first_bubble_line.n'} and
11069: $env{"form.scantron.sub_bubblelines.n"}
11070: which are the total number of bubble lines, the number of bubble
11071: lines for response n and number of the first bubble line for response n,
11072: and a comma separated list of numbers of bubble lines for sub-questions
11073: (for optionresponse, matchresponse, and rankresponse items), for response n.
11074:
11075:
11076: =item scantron_validate_missingbubbles() :
11077:
11078: Validates all scanlines in the selected file to not have any
11079: answers that don't have bubbles that have not been verified
11080: to be bubble free.
11081:
11082: =item scantron_process_students() :
11083:
11084: Routine that does the actual grading of the bubblesheet information.
11085:
11086: The parsed scanline hash is added to %env
11087:
11088: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
11089: foreach resource , with the form data of
11090:
11091: 'submitted' =>'scantron'
11092: 'grade_target' =>'grade',
11093: 'grade_username'=> username of student
11094: 'grade_domain' => domain of student
11095: 'grade_courseid'=> of course
11096: 'grade_symb' => symb of resource to grade
11097:
11098: This triggers a grading pass. The problem grading code takes care
11099: of converting the bubbled letter information (now in %env) into a
11100: valid submission.
11101:
11102: =item scantron_upload_scantron_data() :
11103:

11116:
11117: Shows a list of the three internal files (original, corrected,
11118: skipped) for a specific bubblesheet data file that exists in the
11119: course.
11120:
11121: =item scantron_validate_ID() :
11122:
11123: Validates all scanlines in the selected file to not have any
11124: invalid or underspecified student/employee IDs
11125:
11126: =item navmap_errormsg() :
11127:
11128: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
