5959: =head1 Bubble sheet grading routines
5960:
5961: For this documentation:
5962:
5963: 'scanline' refers to the full line of characters
5964: from the file that we are parsing that represents one entire sheet
5965:
5966: 'bubble line' refers to the data
5967: representing the line of bubbles that are on the physical bubblesheet
5968:
5969:
5970: The overall process is that a scanned in bubblesheet data is uploaded
5971: into a course. When a user wants to grade, they select a
5972: sequence/folder of resources, a file of bubblesheet info, and pick
5973: one of the predefined configurations for what each scanline looks
5974: like.
5975:
5976: Next each scanline is checked for any errors of either 'missing
5977: bubbles' (it's an error because it may have been mis-scanned
5978: because too light bubbling), 'double bubble' (each bubble line should
5979: have no more than one letter picked), invalid or duplicated CODE,
5980: invalid student/employee ID
5981:
5982: If the CODE option is used that determines the randomization of the
5983: homework problems, either way the student/employee ID is looked up into a
5984: username:domain.
5985:
5986: During the validation phase the instructor can choose to skip scanlines.
5987:
5988: After the validation phase, there are now 3 bubblesheet files
5989:
5990: scantron_original_filename (unmodified original file)
5991: scantron_corrected_filename (file where the corrected information has replaced the original information)
5992: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5993:
5994: Also there is a separate hash nohist_scantrondata that contains extra
5995: correction information that isn't representable in the bubblesheet
5996: file (see &scantron_getfile() for more information)
5997:
5998: After all scanlines are either valid, marked as valid or skipped, then
5999: foreach line foreach problem in the picked sequence, an ssi request is
6000: made that simulates a user submitting their selected letter(s) against
6001: the homework problem.

11499: =head1 NAME
11500:
11501: Apache::grades
11502:
11503: =head1 SYNOPSIS
11504:
11505: Handles the viewing of grades.
11506:
11507: This is part of the LearningOnline Network with CAPA project
11508: described at http://www.lon-capa.org.
11509:
11510: =head1 OVERVIEW
11511:
11512: Do an ssi with retries:
11513: While I'd love to factor out this with the vesrion in lonprintout,
11514: 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
11515: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11516:
11517: At least the logic that drives this has been pulled out into loncommon.
11518:
11519:
11520:
11521: ssi_with_retries - Does the server side include of a resource.
11522: if the ssi call returns an error we'll retry it up to
11523: the number of times requested by the caller.
11524: If we still have a problem, no text is appended to the
11525: output and we set some global variables.
11526: to indicate to the caller an SSI error occurred.
11527: All of this is supposed to deal with the issues described
11528: in LON-CAPA BZ 5631 see:
11529: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11530: by informing the user that this happened.
11531:
11532: Parameters:
11533: resource - The resource to include. This is passed directly, without
11534: interpretation to lonnet::ssi.
11535: form - The form hash parameters that guide the interpretation of the resource
11536:
11537: retries - Number of retries allowed before giving up completely.
11538: Returns:
11539: On success, returns the rendered resource identified by the resource parameter.
11540: Side Effects:
11541: The following global variables can be set:
11542: ssi_error - If an unrecoverable error occurred this becomes true.
11543: It is up to the caller to initialize this to false
11544: if desired.
11545: ssi_error_resource - If an unrecoverable error occurred, this is the value
11546: of the resource that could not be rendered by the ssi
11547: call.
11548: ssi_error_message - The error string fetched from the ssi response
11549: in the event of an error.

11560: =item scantron_get_correction() :
11561:
11562: Builds the interface screen to interact with the operator to fix a
11563: specific error condition in a specific scanline
11564:
11565: Arguments:
11566: $r - Apache request object
11567: $i - number of the current scanline
11568: $scan_record - hash ref as returned from &scantron_parse_scanline()
11569: $scan_config - hash ref as returned from &Apache::lonnet::get_scantron_config()
11570: $line - full contents of the current scanline
11571: $error - error condition, valid values are
11572: 'incorrectCODE', 'duplicateCODE',
11573: 'doublebubble', 'missingbubble',
11574: 'duplicateID', 'incorrectID'
11575: $arg - extra information needed
11576: For errors:
11577: - duplicateID - paper number that this studentID was seen before on
11578: - duplicateCODE - array ref of the paper numbers this CODE was
11579: seen on before
11580: - incorrectCODE - current incorrect CODE
11581: - doublebubble - array ref of the bubble lines that have double
11582: bubble errors
11583: - missingbubble - array ref of the bubble lines that have missing
11584: bubble errors
11585:
11586: $randomorder - True if exam folder (or a sub-folder) has randomorder set
11587: $randompick - True if exam folder (or a sub-folder) has randompick set
11588: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
11589: for current line to question number used for same question
11590: in "Master Seqence" (as seen by Course Coordinator).
11591: $startline - Reference to hash where key is question number (0 is first)
11592: and value is number of first bubble line for current student
11593: or code-based randompick and/or randomorder.
11594:
11595:
11596: =item scantron_get_maxbubble() :
11597:
11598: Arguments:
11599: $nav_error - Reference to scalar which is a flag to indicate a
11600: failure to retrieve a navmap object.
11601: if $nav_error is set to 1 by scantron_get_maxbubble(), the
11602: calling routine should trap the error condition and display the warning
11603: found in &navmap_errormsg().
11604:
11605: $scantron_config - Reference to bubblesheet format configuration hash.
11606:
11607: Returns the maximum number of bubble lines that are expected to
11608: occur. Does this by walking the selected sequence rendering the
11609: resource and then checking &Apache::lonxml::get_problem_counter()
11610: for what the current value of the problem counter is.
11611:
11612: Caches the results to $env{'form.scantron_maxbubble'},
11613: $env{'form.scantron.bubble_lines.n'},
11614: $env{'form.scantron.first_bubble_line.n'} and
11615: $env{"form.scantron.sub_bubblelines.n"}
11616: which are the total number of bubble lines, the number of bubble
11617: lines for response n and number of the first bubble line for response n,
11618: and a comma separated list of numbers of bubble lines for sub-questions
11619: (for optionresponse, matchresponse, and rankresponse items), for response n.
11620:
11621:
11622: =item scantron_validate_missingbubbles() :
11623:
11624: Validates all scanlines in the selected file to not have any
11625: answers that don't have bubbles that have not been verified
11626: to be bubble free.
11627:
11628: =item scantron_process_students() :
11629:
11630: Routine that does the actual grading of the bubblesheet information.
11631:
11632: The parsed scanline hash is added to %env
11633:
11634: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
11635: foreach resource , with the form data of
11636:
11637: 'submitted' =>'scantron'
11638: 'grade_target' =>'grade',
11639: 'grade_username'=> username of student
11640: 'grade_domain' => domain of student
11641: 'grade_courseid'=> of course
11642: 'grade_symb' => symb of resource to grade
11643:
11644: This triggers a grading pass. The problem grading code takes care
11645: of converting the bubbled letter information (now in %env) into a
11646: valid submission.
11647:
11648: =item scantron_upload_scantron_data() :

11667: =item scantron_validate_ID() :
11668:
11669: Validates all scanlines in the selected file to not have any
11670: invalid or underspecified student/employee IDs
11671:
11672: =item navmap_errormsg() :
