5257: =head1 Bubble sheet grading routines
5258:
5259: For this documentation:
5260:
5261: 'scanline' refers to the full line of characters
5262: from the file that we are parsing that represents one entire sheet
5263:
5264: 'bubble line' refers to the data
5265: representing the line of bubbles that are on the physical bubblesheet
5266:
5267:
5268: The overall process is that a scanned in bubblesheet data is uploaded
5269: into a course. When a user wants to grade, they select a
5270: sequence/folder of resources, a file of bubblesheet info, and pick
5271: one of the predefined configurations for what each scanline looks
5272: like.
5273:
5274: Next each scanline is checked for any errors of either 'missing
5275: bubbles' (it's an error because it may have been mis-scanned
5276: because too light bubbling), 'double bubble' (each bubble line should
5277: have no more than one letter picked), invalid or duplicated CODE,
5278: invalid student/employee ID
5279:
5280: If the CODE option is used that determines the randomization of the
5281: homework problems, either way the student/employee ID is looked up into a
5282: username:domain.
5283:
5284: During the validation phase the instructor can choose to skip scanlines.
5285:
5286: After the validation phase, there are now 3 bubblesheet files
5287:
5288: scantron_original_filename (unmodified original file)
5289: scantron_corrected_filename (file where the corrected information has replaced the original information)
5290: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5291:
5292: Also there is a separate hash nohist_scantrondata that contains extra
5293: correction information that isn't representable in the bubblesheet
5294: file (see &scantron_getfile() for more information)
5295:
5296: After all scanlines are either valid, marked as valid or skipped, then
5297: foreach line foreach problem in the picked sequence, an ssi request is
5298: made that simulates a user submitting their selected letter(s) against
5299: the homework problem.

10568: =head1 NAME
10569:
10570: Apache::grades
10571:
10572: =head1 SYNOPSIS
10573:
10574: Handles the viewing of grades.
10575:
10576: This is part of the LearningOnline Network with CAPA project
10577: described at http://www.lon-capa.org.
10578:
10579: =head1 OVERVIEW
10580:
10581: Do an ssi with retries:
10582: While I'd love to factor out this with the vesrion in lonprintout,
10583: 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
10584: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10585:
10586: At least the logic that drives this has been pulled out into loncommon.
10587:
10588:
10589:
10590: ssi_with_retries - Does the server side include of a resource.
10591: if the ssi call returns an error we'll retry it up to
10592: the number of times requested by the caller.
10593: If we still have a problem, no text is appended to the
10594: output and we set some global variables.
10595: to indicate to the caller an SSI error occurred.
10596: All of this is supposed to deal with the issues described
10597: in LON-CAPA BZ 5631 see:
10598: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10599: by informing the user that this happened.
10600:
10601: Parameters:
10602: resource - The resource to include. This is passed directly, without
10603: interpretation to lonnet::ssi.
10604: form - The form hash parameters that guide the interpretation of the resource
10605:
10606: retries - Number of retries allowed before giving up completely.
10607: Returns:
10608: On success, returns the rendered resource identified by the resource parameter.
10609: Side Effects:
10610: The following global variables can be set:
10611: ssi_error - If an unrecoverable error occurred this becomes true.
10612: It is up to the caller to initialize this to false
10613: if desired.
10614: ssi_error_resource - If an unrecoverable error occurred, this is the value
10615: of the resource that could not be rendered by the ssi
10616: call.
10617: ssi_error_message - The error string fetched from the ssi response
10618: in the event of an error.

10628:
10629: =item scantron_get_correction() :
10630:
10631: Builds the interface screen to interact with the operator to fix a
10632: specific error condition in a specific scanline
10633:
10634: Arguments:
10635: $r - Apache request object
10636: $i - number of the current scanline
10637: $scan_record - hash ref as returned from &scantron_parse_scanline()
10638: $scan_config - hash ref as returned from &get_scantron_config()
10639: $line - full contents of the current scanline
10640: $error - error condition, valid values are
10641: 'incorrectCODE', 'duplicateCODE',
10642: 'doublebubble', 'missingbubble',
10643: 'duplicateID', 'incorrectID'
10644: $arg - extra information needed
10645: For errors:
10646: - duplicateID - paper number that this studentID was seen before on
10647: - duplicateCODE - array ref of the paper numbers this CODE was
10648: seen on before
10649: - incorrectCODE - current incorrect CODE
10650: - doublebubble - array ref of the bubble lines that have double
10651: bubble errors
10652: - missingbubble - array ref of the bubble lines that have missing
10653: bubble errors
10654:
10655: $randomorder - True if exam folder has randomorder set
10656: $randompick - True if exam folder has randompick set
10657: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
10658: for current line to question number used for same question
10659: in "Master Seqence" (as seen by Course Coordinator).
10660: $startline - Reference to hash where key is question number (0 is first)
10661: and value is number of first bubble line for current student
10662: or code-based randompick and/or randomorder.
10663:
10664:
10665: =item scantron_get_maxbubble() :
10666:
10667: Arguments:
10668: $nav_error - Reference to scalar which is a flag to indicate a
10669: failure to retrieve a navmap object.
10670: if $nav_error is set to 1 by scantron_get_maxbubble(), the
10671: calling routine should trap the error condition and display the warning
10672: found in &navmap_errormsg().
10673:
10674: $scantron_config - Reference to bubblesheet format configuration hash.
10675:
10676: Returns the maximum number of bubble lines that are expected to
10677: occur. Does this by walking the selected sequence rendering the
10678: resource and then checking &Apache::lonxml::get_problem_counter()
10679: for what the current value of the problem counter is.
10680:
10681: Caches the results to $env{'form.scantron_maxbubble'},
10682: $env{'form.scantron.bubble_lines.n'},
10683: $env{'form.scantron.first_bubble_line.n'} and
10684: $env{"form.scantron.sub_bubblelines.n"}
10685: which are the total number of bubble lines, the number of bubble
10686: lines for response n and number of the first bubble line for response n,
10687: and a comma separated list of numbers of bubble lines for sub-questions
10688: (for optionresponse, matchresponse, and rankresponse items), for response n.
10689:
10690:
10691: =item scantron_validate_missingbubbles() :
10692:
10693: Validates all scanlines in the selected file to not have any
10694: answers that don't have bubbles that have not been verified
10695: to be bubble free.
10696:
10697: =item scantron_process_students() :
10698:
10699: Routine that does the actual grading of the bubblesheet information.
10700:
10701: The parsed scanline hash is added to %env
10702:
10703: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
10704: foreach resource , with the form data of
10705:
10706: 'submitted' =>'scantron'
10707: 'grade_target' =>'grade',
10708: 'grade_username'=> username of student
10709: 'grade_domain' => domain of student
10710: 'grade_courseid'=> of course
10711: 'grade_symb' => symb of resource to grade
10712:
10713: This triggers a grading pass. The problem grading code takes care
10714: of converting the bubbled letter information (now in %env) into a
10715: valid submission.
10716:
10717: =item scantron_upload_scantron_data() :

10734: course.
10735:
10736: =item scantron_validate_ID() :
10737:
10738: Validates all scanlines in the selected file to not have any
10739: invalid or underspecified student/employee IDs
