1.424 albertel 4802: For this documentation:
4803:
4804: 'scanline' refers to the full line of characters
4805: from the file that we are parsing that represents one entire sheet
4806:
4807: 'bubble line' refers to the data
4808: representing the line of bubbles that are on the physical bubble sheet
4809:
4810:
4811: The overall process is that a scanned in bubble sheet data is uploaded
4812: into a course. When a user wants to grade, they select a
4813: sequence/folder of resources, a file of bubble sheet info, and pick
4814: one of the predefined configurations for what each scanline looks
4815: like.
4816:
4817: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4818: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4819: because too light bubbling), 'double bubble' (each bubble line should
4820: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4821: invalid student/employee ID
1.424 albertel 4822:
4823: If the CODE option is used that determines the randomization of the
1.556 weissno 4824: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4825: username:domain.
4826:
4827: During the validation phase the instructor can choose to skip scanlines.
4828:
1.435 foxr 4829: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4830:
4831: scantron_original_filename (unmodified original file)
4832: scantron_corrected_filename (file where the corrected information has replaced the original information)

9398: =head1 NAME
9399:
9400: Apache::grades
9401:
9402: =head1 SYNOPSIS
9403:
9404: Handles the viewing of grades.
9405:
9406: This is part of the LearningOnline Network with CAPA project
9407: described at http://www.lon-capa.org.
9408:
9409: =head1 OVERVIEW
9410:
9411: Do an ssi with retries:
9412: While I'd love to factor out this with the vesrion in lonprintout,
9413: 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
9414: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9415:
9416: At least the logic that drives this has been pulled out into loncommon.
9417:
9418:
9419:
9420: ssi_with_retries - Does the server side include of a resource.
9421: if the ssi call returns an error we'll retry it up to
9422: the number of times requested by the caller.
9423: If we still have a proble, no text is appended to the
9424: output and we set some global variables.
9425: to indicate to the caller an SSI error occurred.
9426: All of this is supposed to deal with the issues described
9427: in LonCAPA BZ 5631 see:
9428: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9429: by informing the user that this happened.
9430:
9431: Parameters:
9432: resource - The resource to include. This is passed directly, without
9433: interpretation to lonnet::ssi.
9434: form - The form hash parameters that guide the interpretation of the resource
9435:
9436: retries - Number of retries allowed before giving up completely.
9437: Returns:
9438: On success, returns the rendered resource identified by the resource parameter.
9439: Side Effects:
9440: The following global variables can be set:
9441: ssi_error - If an unrecoverable error occurred this becomes true.
9442: It is up to the caller to initialize this to false
9443: if desired.
9444: ssi_error_resource - If an unrecoverable error occurred, this is the value
9445: of the resource that could not be rendered by the ssi
9446: call.
9447: ssi_error_message - The error string fetched from the ssi response
9448: in the event of an error.

9459: =item scantron_get_correction() :
9460:
9461: Builds the interface screen to interact with the operator to fix a
9462: specific error condition in a specific scanline
9463:
9464: Arguments:
9465: $r - Apache request object
9466: $i - number of the current scanline
9467: $scan_record - hash ref as returned from &scantron_parse_scanline()
9468: $scan_config - hash ref as returned from &get_scantron_config()
9469: $line - full contents of the current scanline
9470: $error - error condition, valid values are
9471: 'incorrectCODE', 'duplicateCODE',
9472: 'doublebubble', 'missingbubble',
9473: 'duplicateID', 'incorrectID'
9474: $arg - extra information needed
9475: For errors:
9476: - duplicateID - paper number that this studentID was seen before on
9477: - duplicateCODE - array ref of the paper numbers this CODE was
9478: seen on before
9479: - incorrectCODE - current incorrect CODE
9480: - doublebubble - array ref of the bubble lines that have double
9481: bubble errors
9482: - missingbubble - array ref of the bubble lines that have missing
9483: bubble errors
9484:
9485: =item scantron_get_maxbubble() :
9486:
1.582 raeburn 9487: Arguments:
9488: $nav_error - Reference to scalar which is a flag to indicate a
9489: failure to retrieve a navmap object.
9490: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9491: calling routine should trap the error condition and display the warning
9492: found in &navmap_errormsg().
9493:
1.531 jms 9494: Returns the maximum number of bubble lines that are expected to
9495: occur. Does this by walking the selected sequence rendering the
9496: resource and then checking &Apache::lonxml::get_problem_counter()
9497: for what the current value of the problem counter is.
9498:
9499: Caches the results to $env{'form.scantron_maxbubble'},
9500: $env{'form.scantron.bubble_lines.n'},
9501: $env{'form.scantron.first_bubble_line.n'} and
9502: $env{"form.scantron.sub_bubblelines.n"}
9503: which are the total number of bubble, lines, the number of bubble
9504: lines for response n and number of the first bubble line for response n,
9505: and a comma separated list of numbers of bubble lines for sub-questions
9506: (for optionresponse, matchresponse, and rankresponse items), for response n.

9514:
9515: =item scantron_process_students() :
9516:
9517: Routine that does the actual grading of the bubble sheet information.
9518:
9519: The parsed scanline hash is added to %env
9520:
9521: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9522: foreach resource , with the form data of
9523:
9524: 'submitted' =>'scantron'
9525: 'grade_target' =>'grade',
9526: 'grade_username'=> username of student
9527: 'grade_domain' => domain of student
9528: 'grade_courseid'=> of course
9529: 'grade_symb' => symb of resource to grade
9530:
9531: This triggers a grading pass. The problem grading code takes care
9532: of converting the bubbled letter information (now in %env) into a
9533: valid submission.

9552: course.
9553:
9554: =item scantron_validate_ID() :
