5942: =head1 Bubble sheet grading routines
5943:
5944: For this documentation:
5945:
5946: 'scanline' refers to the full line of characters
5947: from the file that we are parsing that represents one entire sheet
5948:
5949: 'bubble line' refers to the data
5950: representing the line of bubbles that are on the physical bubblesheet
5951:
5952:
5953: The overall process is that a scanned in bubblesheet data is uploaded
5954: into a course. When a user wants to grade, they select a
5955: sequence/folder of resources, a file of bubblesheet info, and pick
5956: one of the predefined configurations for what each scanline looks
5957: like.
5958:
5959: Next each scanline is checked for any errors of either 'missing
5960: bubbles' (it's an error because it may have been mis-scanned
5961: because too light bubbling), 'double bubble' (each bubble line should
5962: have no more than one letter picked), invalid or duplicated CODE,
5963: invalid student/employee ID
5964:
5965: If the CODE option is used that determines the randomization of the
5966: homework problems, either way the student/employee ID is looked up into a
5967: username:domain.
5968:
5969: During the validation phase the instructor can choose to skip scanlines.
5970:
5971: After the validation phase, there are now 3 bubblesheet files
5972:
5973: scantron_original_filename (unmodified original file)
5974: scantron_corrected_filename (file where the corrected information has replaced the original information)
5975: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5976:
5977: Also there is a separate hash nohist_scantrondata that contains extra
5978: correction information that isn't representable in the bubblesheet
5979: file (see &scantron_getfile() for more information)
5980:
5981: After all scanlines are either valid, marked as valid or skipped, then
5982: foreach line foreach problem in the picked sequence, an ssi request is
5983: made that simulates a user submitting their selected letter(s) against
5984: the homework problem.

11411: =head1 NAME
11412:
11413: Apache::grades
11414:
11415: =head1 SYNOPSIS
11416:
11417: Handles the viewing of grades.
11418:
11419: This is part of the LearningOnline Network with CAPA project
11420: described at http://www.lon-capa.org.
11421:
11422: =head1 OVERVIEW
11423:
11424: Do an ssi with retries:
11425: While I'd love to factor out this with the vesrion in lonprintout,
11426: 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
11427: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11428:
11429: At least the logic that drives this has been pulled out into loncommon.
11430:
11431:
11432:
11433: ssi_with_retries - Does the server side include of a resource.
11434: if the ssi call returns an error we'll retry it up to
11435: the number of times requested by the caller.
11436: If we still have a problem, no text is appended to the
11437: output and we set some global variables.
11438: to indicate to the caller an SSI error occurred.
11439: All of this is supposed to deal with the issues described
11440: in LON-CAPA BZ 5631 see:
11441: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11442: by informing the user that this happened.
11443:
11444: Parameters:
11445: resource - The resource to include. This is passed directly, without
11446: interpretation to lonnet::ssi.
11447: form - The form hash parameters that guide the interpretation of the resource
11448:
11449: retries - Number of retries allowed before giving up completely.
11450: Returns:
11451: On success, returns the rendered resource identified by the resource parameter.
11452: Side Effects:
11453: The following global variables can be set:
11454: ssi_error - If an unrecoverable error occurred this becomes true.
11455: It is up to the caller to initialize this to false
11456: if desired.
11457: ssi_error_resource - If an unrecoverable error occurred, this is the value
11458: of the resource that could not be rendered by the ssi
11459: call.
11460: ssi_error_message - The error string fetched from the ssi response
11461: in the event of an error.

11471:
11472: =item scantron_get_correction() :
11473:
11474: Builds the interface screen to interact with the operator to fix a
11475: specific error condition in a specific scanline
11476:
11477: Arguments:
11478: $r - Apache request object
11479: $i - number of the current scanline
11480: $scan_record - hash ref as returned from &scantron_parse_scanline()
11481: $scan_config - hash ref as returned from &Apache::lonnet::get_scantron_config()
11482: $line - full contents of the current scanline
11483: $error - error condition, valid values are
11484: 'incorrectCODE', 'duplicateCODE',
11485: 'doublebubble', 'missingbubble',
11486: 'duplicateID', 'incorrectID'
11487: $arg - extra information needed
11488: For errors:
11489: - duplicateID - paper number that this studentID was seen before on
11490: - duplicateCODE - array ref of the paper numbers this CODE was
11491: seen on before
11492: - incorrectCODE - current incorrect CODE
11493: - doublebubble - array ref of the bubble lines that have double
11494: bubble errors
11495: - missingbubble - array ref of the bubble lines that have missing
11496: bubble errors
11497:
11498: $randomorder - True if exam folder (or a sub-folder) has randomorder set
11499: $randompick - True if exam folder (or a sub-folder) has randompick set
11500: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
11501: for current line to question number used for same question
11502: in "Master Seqence" (as seen by Course Coordinator).
11503: $startline - Reference to hash where key is question number (0 is first)
11504: and value is number of first bubble line for current student
11505: or code-based randompick and/or randomorder.
11506:
11507:
11508: =item scantron_get_maxbubble() :
11509:
11510: Arguments:
11511: $nav_error - Reference to scalar which is a flag to indicate a
11512: failure to retrieve a navmap object.
11513: if $nav_error is set to 1 by scantron_get_maxbubble(), the
11514: calling routine should trap the error condition and display the warning
11515: found in &navmap_errormsg().
11516:
11517: $scantron_config - Reference to bubblesheet format configuration hash.
11518:
11519: Returns the maximum number of bubble lines that are expected to
11520: occur. Does this by walking the selected sequence rendering the
11521: resource and then checking &Apache::lonxml::get_problem_counter()
11522: for what the current value of the problem counter is.
11523:
11524: Caches the results to $env{'form.scantron_maxbubble'},
11525: $env{'form.scantron.bubble_lines.n'},
11526: $env{'form.scantron.first_bubble_line.n'} and
11527: $env{"form.scantron.sub_bubblelines.n"}
11528: which are the total number of bubble lines, the number of bubble
11529: lines for response n and number of the first bubble line for response n,
11530: and a comma separated list of numbers of bubble lines for sub-questions
11531: (for optionresponse, matchresponse, and rankresponse items), for response n.
11532:
11533:
11534: =item scantron_validate_missingbubbles() :
11535:
11536: Validates all scanlines in the selected file to not have any
11537: answers that don't have bubbles that have not been verified
11538: to be bubble free.
11539:
11540: =item scantron_process_students() :
11541:
11542: Routine that does the actual grading of the bubblesheet information.
11543:
11544: The parsed scanline hash is added to %env
11545:
11546: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
11547: foreach resource , with the form data of
11548:
11549: 'submitted' =>'scantron'
11550: 'grade_target' =>'grade',
11551: 'grade_username'=> username of student
11552: 'grade_domain' => domain of student
11553: 'grade_courseid'=> of course
11554: 'grade_symb' => symb of resource to grade
11555:
11556: This triggers a grading pass. The problem grading code takes care
11557: of converting the bubbled letter information (now in %env) into a
11558: valid submission.
11559:
11560: =item scantron_upload_scantron_data() :

11575: Shows a list of the three internal files (original, corrected,
11576: skipped) for a specific bubblesheet data file that exists in the
11577: course.
11578:
11579: =item scantron_validate_ID() :
11580:
11581: Validates all scanlines in the selected file to not have any
11582: invalid or underspecified student/employee IDs
11583:
11584: =item navmap_errormsg() :
