4845: =head1 Bubble sheet grading routines
4846:
4847: For this documentation:
4848:
4849: 'scanline' refers to the full line of characters
4850: from the file that we are parsing that represents one entire sheet
4851:
4852: 'bubble line' refers to the data
4853: representing the line of bubbles that are on the physical bubble sheet
4854:
4855:
4856: The overall process is that a scanned in bubble sheet data is uploaded
4857: into a course. When a user wants to grade, they select a
4858: sequence/folder of resources, a file of bubble sheet info, and pick
4859: one of the predefined configurations for what each scanline looks
4860: like.
4861:
4862: Next each scanline is checked for any errors of either 'missing
4863: bubbles' (it's an error because it may have been mis-scanned
4864: because too light bubbling), 'double bubble' (each bubble line should
4865: have no more that one letter picked), invalid or duplicated CODE,
4866: invalid student/employee ID
4867:
4868: If the CODE option is used that determines the randomization of the
4869: homework problems, either way the student/employee ID is looked up into a
4870: username:domain.
4871:
4872: During the validation phase the instructor can choose to skip scanlines.
4873:
4874: After the validation phase, there are now 3 bubble sheet files
4875:
4876: scantron_original_filename (unmodified original file)
4877: scantron_corrected_filename (file where the corrected information has replaced the original information)
4878: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4879:
4880: Also there is a separate hash nohist_scantrondata that contains extra

9392: =head1 NAME
9393:
9394: Apache::grades
9395:
9396: =head1 SYNOPSIS
9397:
9398: Handles the viewing of grades.
9399:
9400: This is part of the LearningOnline Network with CAPA project
9401: described at http://www.lon-capa.org.
9402:
9403: =head1 OVERVIEW
9404:
9405: Do an ssi with retries:
9406: While I'd love to factor out this with the vesrion in lonprintout,
9407: 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
9408: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9409:
9410: At least the logic that drives this has been pulled out into loncommon.
9411:
9412:
9413:
9414: ssi_with_retries - Does the server side include of a resource.
9415: if the ssi call returns an error we'll retry it up to
9416: the number of times requested by the caller.
9417: If we still have a proble, no text is appended to the
9418: output and we set some global variables.
9419: to indicate to the caller an SSI error occurred.
9420: All of this is supposed to deal with the issues described
9421: in LonCAPA BZ 5631 see:
9422: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9423: by informing the user that this happened.
9424:
9425: Parameters:
9426: resource - The resource to include. This is passed directly, without
9427: interpretation to lonnet::ssi.
9428: form - The form hash parameters that guide the interpretation of the resource
9429:
9430: retries - Number of retries allowed before giving up completely.
9431: Returns:
9432: On success, returns the rendered resource identified by the resource parameter.
9433: Side Effects:
9434: The following global variables can be set:
9435: ssi_error - If an unrecoverable error occurred this becomes true.
9436: It is up to the caller to initialize this to false
9437: if desired.
9438: ssi_error_resource - If an unrecoverable error occurred, this is the value
9439: of the resource that could not be rendered by the ssi
9440: call.
9441: ssi_error_message - The error string fetched from the ssi response
9442: in the event of an error.

9455: Builds the interface screen to interact with the operator to fix a

9457:
9458: Arguments:
9459: $r - Apache request object
9460: $i - number of the current scanline
9461: $scan_record - hash ref as returned from &scantron_parse_scanline()
9462: $scan_config - hash ref as returned from &get_scantron_config()
9463: $line - full contents of the current scanline
9464: $error - error condition, valid values are
9465: 'incorrectCODE', 'duplicateCODE',
9466: 'doublebubble', 'missingbubble',
9467: 'duplicateID', 'incorrectID'
9468: $arg - extra information needed
9469: For errors:
9470: - duplicateID - paper number that this studentID was seen before on
9471: - duplicateCODE - array ref of the paper numbers this CODE was
9472: seen on before
9473: - incorrectCODE - current incorrect CODE
9474: - doublebubble - array ref of the bubble lines that have double
9475: bubble errors

9477: bubble errors

9482: $nav_error - Reference to scalar which is a flag to indicate a
9483: failure to retrieve a navmap object.
9484: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9485: calling routine should trap the error condition and display the warning
9486: found in &navmap_errormsg().
9487:
9488: Returns the maximum number of bubble lines that are expected to
9489: occur. Does this by walking the selected sequence rendering the
9490: resource and then checking &Apache::lonxml::get_problem_counter()
9491: for what the current value of the problem counter is.
9492:
9493: Caches the results to $env{'form.scantron_maxbubble'},
9494: $env{'form.scantron.bubble_lines.n'},
9495: $env{'form.scantron.first_bubble_line.n'} and
9496: $env{"form.scantron.sub_bubblelines.n"}
9497: which are the total number of bubble, lines, the number of bubble
9498: lines for response n and number of the first bubble line for response n,
9499: and a comma separated list of numbers of bubble lines for sub-questions
9500: (for optionresponse, matchresponse, and rankresponse items), for response n.
