4935:
1.424 albertel 4936: For this documentation:
4937:
4938: 'scanline' refers to the full line of characters
4939: from the file that we are parsing that represents one entire sheet
4940:
4941: 'bubble line' refers to the data
4942: representing the line of bubbles that are on the physical bubble sheet
4943:
4944:
4945: The overall process is that a scanned in bubble sheet data is uploaded
4946: into a course. When a user wants to grade, they select a
4947: sequence/folder of resources, a file of bubble sheet info, and pick
4948: one of the predefined configurations for what each scanline looks
4949: like.
4950:
4951: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4952: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4953: because too light bubbling), 'double bubble' (each bubble line should
4954: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4955: invalid student/employee ID
1.424 albertel 4956:
4957: If the CODE option is used that determines the randomization of the
1.556 weissno 4958: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4959: username:domain.
4960:
4961: During the validation phase the instructor can choose to skip scanlines.
4962:
1.435 foxr 4963: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4964:
4965: scantron_original_filename (unmodified original file)
4966: scantron_corrected_filename (file where the corrected information has replaced the original information)
4967: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4968:
4969: Also there is a separate hash nohist_scantrondata that contains extra
4970: correction information that isn't representable in the bubble sheet
4971: file (see &scantron_getfile() for more information)
4972:
4973: After all scanlines are either valid, marked as valid or skipped, then
4974: foreach line foreach problem in the picked sequence, an ssi request is
4975: made that simulates a user submitting their selected letter(s) against
4976: the homework problem.

9556: =head1 NAME
9557:
9558: Apache::grades
9559:
9560: =head1 SYNOPSIS
9561:
9562: Handles the viewing of grades.
9563:
9564: This is part of the LearningOnline Network with CAPA project
9565: described at http://www.lon-capa.org.
9566:
9567: =head1 OVERVIEW
9568:
9569: Do an ssi with retries:
9570: While I'd love to factor out this with the vesrion in lonprintout,
9571: 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
9572: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9573:
9574: At least the logic that drives this has been pulled out into loncommon.
9575:
9576:
9577:
9578: ssi_with_retries - Does the server side include of a resource.
9579: if the ssi call returns an error we'll retry it up to
9580: the number of times requested by the caller.
9581: If we still have a proble, no text is appended to the
9582: output and we set some global variables.
9583: to indicate to the caller an SSI error occurred.
9584: All of this is supposed to deal with the issues described
9585: in LonCAPA BZ 5631 see:
9586: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9587: by informing the user that this happened.
9588:
9589: Parameters:
9590: resource - The resource to include. This is passed directly, without
9591: interpretation to lonnet::ssi.
9592: form - The form hash parameters that guide the interpretation of the resource
9593:
9594: retries - Number of retries allowed before giving up completely.
9595: Returns:
9596: On success, returns the rendered resource identified by the resource parameter.
9597: Side Effects:
9598: The following global variables can be set:
9599: ssi_error - If an unrecoverable error occurred this becomes true.
9600: It is up to the caller to initialize this to false
9601: if desired.
9602: ssi_error_resource - If an unrecoverable error occurred, this is the value
9603: of the resource that could not be rendered by the ssi
9604: call.
9605: ssi_error_message - The error string fetched from the ssi response
9606: in the event of an error.

9619: Builds the interface screen to interact with the operator to fix a
9620: specific error condition in a specific scanline
9621:
9622: Arguments:
9623: $r - Apache request object
9624: $i - number of the current scanline
9625: $scan_record - hash ref as returned from &scantron_parse_scanline()
9626: $scan_config - hash ref as returned from &get_scantron_config()
9627: $line - full contents of the current scanline
9628: $error - error condition, valid values are
9629: 'incorrectCODE', 'duplicateCODE',
9630: 'doublebubble', 'missingbubble',
9631: 'duplicateID', 'incorrectID'
9632: $arg - extra information needed
9633: For errors:
9634: - duplicateID - paper number that this studentID was seen before on
9635: - duplicateCODE - array ref of the paper numbers this CODE was
9636: seen on before
9637: - incorrectCODE - current incorrect CODE
9638: - doublebubble - array ref of the bubble lines that have double
9639: bubble errors

9641: bubble errors
9642:
9643: =item scantron_get_maxbubble() :
9644:
1.582 raeburn 9645: Arguments:
9646: $nav_error - Reference to scalar which is a flag to indicate a
9647: failure to retrieve a navmap object.
9648: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9649: calling routine should trap the error condition and display the warning
9650: found in &navmap_errormsg().
9651:
1.531 jms 9652: Returns the maximum number of bubble lines that are expected to
9653: occur. Does this by walking the selected sequence rendering the
9654: resource and then checking &Apache::lonxml::get_problem_counter()
9655: for what the current value of the problem counter is.
9656:
9657: Caches the results to $env{'form.scantron_maxbubble'},

9659: $env{'form.scantron.first_bubble_line.n'} and
9660: $env{"form.scantron.sub_bubblelines.n"}
9661: which are the total number of bubble, lines, the number of bubble
9662: lines for response n and number of the first bubble line for response n,
9663: and a comma separated list of numbers of bubble lines for sub-questions
9664: (for optionresponse, matchresponse, and rankresponse items), for response n.

9673: =item scantron_process_students() :
9674:
9675: Routine that does the actual grading of the bubble sheet information.
9676:
9677: The parsed scanline hash is added to %env
9678:
9679: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9680: foreach resource , with the form data of
9681:
9682: 'submitted' =>'scantron'
9683: 'grade_target' =>'grade',

9685: 'grade_domain' => domain of student
9686: 'grade_courseid'=> of course
9687: 'grade_symb' => symb of resource to grade
9688:
9689: This triggers a grading pass. The problem grading code takes care
9690: of converting the bubbled letter information (now in %env) into a
9691: valid submission.
