4850: 'bubble line' refers to the data
4851: representing the line of bubbles that are on the physical bubble sheet
4852:
4853:
4854: The overall process is that a scanned in bubble sheet data is uploaded
4855: into a course. When a user wants to grade, they select a
4856: sequence/folder of resources, a file of bubble sheet info, and pick
4857: one of the predefined configurations for what each scanline looks
4858: like.
4859:
4860: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4861: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4862: because too light bubbling), 'double bubble' (each bubble line should
4863: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4864: invalid student/employee ID
1.424 albertel 4865:
4866: If the CODE option is used that determines the randomization of the
1.556 weissno 4867: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4868: username:domain.
4869:
4870: During the validation phase the instructor can choose to skip scanlines.

1.435 foxr 4872: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4873:
4874: scantron_original_filename (unmodified original file)
4875: scantron_corrected_filename (file where the corrected information has replaced the original information)
4876: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4877:
4878: Also there is a separate hash nohist_scantrondata that contains extra
4879: correction information that isn't representable in the bubble sheet
4880: file (see &scantron_getfile() for more information)
4881:
4882: After all scanlines are either valid, marked as valid or skipped, then
4883: foreach line foreach problem in the picked sequence, an ssi request is
4884: made that simulates a user submitting their selected letter(s) against
4885: the homework problem.

9465: =head1 NAME
9466:
9467: Apache::grades
9468:
9469: =head1 SYNOPSIS
9470:
9471: Handles the viewing of grades.
9472:
9473: This is part of the LearningOnline Network with CAPA project
9474: described at http://www.lon-capa.org.
9475:
9476: =head1 OVERVIEW
9477:
9478: Do an ssi with retries:
9479: While I'd love to factor out this with the vesrion in lonprintout,
9480: 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
9481: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9482:
9483: At least the logic that drives this has been pulled out into loncommon.
9484:
9485:
9486:
9487: ssi_with_retries - Does the server side include of a resource.
9488: if the ssi call returns an error we'll retry it up to
9489: the number of times requested by the caller.
9490: If we still have a proble, no text is appended to the
9491: output and we set some global variables.
9492: to indicate to the caller an SSI error occurred.
9493: All of this is supposed to deal with the issues described
9494: in LonCAPA BZ 5631 see:
9495: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9496: by informing the user that this happened.
9497:
9498: Parameters:
9499: resource - The resource to include. This is passed directly, without
9500: interpretation to lonnet::ssi.
9501: form - The form hash parameters that guide the interpretation of the resource
9502:
9503: retries - Number of retries allowed before giving up completely.
9504: Returns:
9505: On success, returns the rendered resource identified by the resource parameter.
9506: Side Effects:
9507: The following global variables can be set:
9508: ssi_error - If an unrecoverable error occurred this becomes true.
9509: It is up to the caller to initialize this to false
9510: if desired.
9511: ssi_error_resource - If an unrecoverable error occurred, this is the value
9512: of the resource that could not be rendered by the ssi
9513: call.
9514: ssi_error_message - The error string fetched from the ssi response
9515: in the event of an error.

9527:
9528: Builds the interface screen to interact with the operator to fix a
9529: specific error condition in a specific scanline
9530:
9531: Arguments:
9532: $r - Apache request object
9533: $i - number of the current scanline
9534: $scan_record - hash ref as returned from &scantron_parse_scanline()
9535: $scan_config - hash ref as returned from &get_scantron_config()
9536: $line - full contents of the current scanline
9537: $error - error condition, valid values are
9538: 'incorrectCODE', 'duplicateCODE',
9539: 'doublebubble', 'missingbubble',
9540: 'duplicateID', 'incorrectID'
9541: $arg - extra information needed
9542: For errors:
9543: - duplicateID - paper number that this studentID was seen before on
9544: - duplicateCODE - array ref of the paper numbers this CODE was
9545: seen on before
9546: - incorrectCODE - current incorrect CODE
9547: - doublebubble - array ref of the bubble lines that have double
9548: bubble errors
9549: - missingbubble - array ref of the bubble lines that have missing
9550: bubble errors
9551:
9552: =item scantron_get_maxbubble() :
9553:
1.582 raeburn 9554: Arguments:
9555: $nav_error - Reference to scalar which is a flag to indicate a
9556: failure to retrieve a navmap object.
9557: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9558: calling routine should trap the error condition and display the warning
9559: found in &navmap_errormsg().
9560:
1.531 jms 9561: Returns the maximum number of bubble lines that are expected to
9562: occur. Does this by walking the selected sequence rendering the
9563: resource and then checking &Apache::lonxml::get_problem_counter()
9564: for what the current value of the problem counter is.
9565:
9566: Caches the results to $env{'form.scantron_maxbubble'},
9567: $env{'form.scantron.bubble_lines.n'},
9568: $env{'form.scantron.first_bubble_line.n'} and
9569: $env{"form.scantron.sub_bubblelines.n"}
9570: which are the total number of bubble, lines, the number of bubble
9571: lines for response n and number of the first bubble line for response n,
9572: and a comma separated list of numbers of bubble lines for sub-questions
9573: (for optionresponse, matchresponse, and rankresponse items), for response n.

9581:
9582: =item scantron_process_students() :
9583:
9584: Routine that does the actual grading of the bubble sheet information.
9585:
9586: The parsed scanline hash is added to %env
9587:
9588: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9589: foreach resource , with the form data of
9590:
9591: 'submitted' =>'scantron'
9592: 'grade_target' =>'grade',
9593: 'grade_username'=> username of student
9594: 'grade_domain' => domain of student
9595: 'grade_courseid'=> of course
9596: 'grade_symb' => symb of resource to grade
9597:
9598: This triggers a grading pass. The problem grading code takes care
9599: of converting the bubbled letter information (now in %env) into a
9600: valid submission.

9619: course.
9620:
