4936:
1.424 albertel 4937: For this documentation:
4938:
4939: 'scanline' refers to the full line of characters
4940: from the file that we are parsing that represents one entire sheet
4941:
4942: 'bubble line' refers to the data
4943: representing the line of bubbles that are on the physical bubble sheet
4944:
4945:
4946: The overall process is that a scanned in bubble sheet data is uploaded
4947: into a course. When a user wants to grade, they select a
4948: sequence/folder of resources, a file of bubble sheet info, and pick
4949: one of the predefined configurations for what each scanline looks
4950: like.
4951:
4952: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4953: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4954: because too light bubbling), 'double bubble' (each bubble line should
4955: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4956: invalid student/employee ID
1.424 albertel 4957:
4958: If the CODE option is used that determines the randomization of the
1.556 weissno 4959: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4960: username:domain.
4961:
4962: During the validation phase the instructor can choose to skip scanlines.
4963:
1.435 foxr 4964: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4965:
4966: scantron_original_filename (unmodified original file)
4967: scantron_corrected_filename (file where the corrected information has replaced the original information)
4968: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4969:
4970: Also there is a separate hash nohist_scantrondata that contains extra
4971: correction information that isn't representable in the bubble sheet
4972: file (see &scantron_getfile() for more information)
4973:
4974: After all scanlines are either valid, marked as valid or skipped, then
4975: foreach line foreach problem in the picked sequence, an ssi request is
4976: made that simulates a user submitting their selected letter(s) against
4977: the homework problem.

9557: =head1 NAME
9558:
9559: Apache::grades
9560:
9561: =head1 SYNOPSIS
9562:
9563: Handles the viewing of grades.
9564:
9565: This is part of the LearningOnline Network with CAPA project
9566: described at http://www.lon-capa.org.
9567:
9568: =head1 OVERVIEW
9569:
9570: Do an ssi with retries:
9571: While I'd love to factor out this with the vesrion in lonprintout,
9572: 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
9573: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9574:
9575: At least the logic that drives this has been pulled out into loncommon.
9576:
9577:
9578:
9579: ssi_with_retries - Does the server side include of a resource.
9580: if the ssi call returns an error we'll retry it up to
9581: the number of times requested by the caller.
9582: If we still have a proble, no text is appended to the
9583: output and we set some global variables.
9584: to indicate to the caller an SSI error occurred.
9585: All of this is supposed to deal with the issues described
9586: in LonCAPA BZ 5631 see:
9587: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9588: by informing the user that this happened.
9589:
9590: Parameters:
9591: resource - The resource to include. This is passed directly, without
9592: interpretation to lonnet::ssi.
9593: form - The form hash parameters that guide the interpretation of the resource
9594:
9595: retries - Number of retries allowed before giving up completely.
9596: Returns:
9597: On success, returns the rendered resource identified by the resource parameter.
9598: Side Effects:
9599: The following global variables can be set:
9600: ssi_error - If an unrecoverable error occurred this becomes true.
9601: It is up to the caller to initialize this to false
9602: if desired.
9603: ssi_error_resource - If an unrecoverable error occurred, this is the value
9604: of the resource that could not be rendered by the ssi
9605: call.
9606: ssi_error_message - The error string fetched from the ssi response
9607: in the event of an error.

9619:
9620: Builds the interface screen to interact with the operator to fix a
9621: specific error condition in a specific scanline
9622:
9623: Arguments:
9624: $r - Apache request object
9625: $i - number of the current scanline
9626: $scan_record - hash ref as returned from &scantron_parse_scanline()
9627: $scan_config - hash ref as returned from &get_scantron_config()
9628: $line - full contents of the current scanline
9629: $error - error condition, valid values are
9630: 'incorrectCODE', 'duplicateCODE',
9631: 'doublebubble', 'missingbubble',
9632: 'duplicateID', 'incorrectID'
9633: $arg - extra information needed
9634: For errors:
9635: - duplicateID - paper number that this studentID was seen before on
9636: - duplicateCODE - array ref of the paper numbers this CODE was
9637: seen on before
9638: - incorrectCODE - current incorrect CODE
9639: - doublebubble - array ref of the bubble lines that have double
9640: bubble errors
9641: - missingbubble - array ref of the bubble lines that have missing
9642: bubble errors
9643:
9644: =item scantron_get_maxbubble() :
9645:
1.582 raeburn 9646: Arguments:
9647: $nav_error - Reference to scalar which is a flag to indicate a
9648: failure to retrieve a navmap object.
9649: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9650: calling routine should trap the error condition and display the warning
9651: found in &navmap_errormsg().
9652:
1.531 jms 9653: Returns the maximum number of bubble lines that are expected to
9654: occur. Does this by walking the selected sequence rendering the
9655: resource and then checking &Apache::lonxml::get_problem_counter()
9656: for what the current value of the problem counter is.
9657:
9658: Caches the results to $env{'form.scantron_maxbubble'},
9659: $env{'form.scantron.bubble_lines.n'},
9660: $env{'form.scantron.first_bubble_line.n'} and
9661: $env{"form.scantron.sub_bubblelines.n"}
9662: which are the total number of bubble, lines, the number of bubble
9663: lines for response n and number of the first bubble line for response n,
9664: and a comma separated list of numbers of bubble lines for sub-questions
9665: (for optionresponse, matchresponse, and rankresponse items), for response n.

9673:
9674: =item scantron_process_students() :
9675:
9676: Routine that does the actual grading of the bubble sheet information.
9677:
9678: The parsed scanline hash is added to %env
9679:
9680: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9681: foreach resource , with the form data of
9682:
9683: 'submitted' =>'scantron'
9684: 'grade_target' =>'grade',
9685: 'grade_username'=> username of student
9686: 'grade_domain' => domain of student
9687: 'grade_courseid'=> of course
9688: 'grade_symb' => symb of resource to grade
9689:
9690: This triggers a grading pass. The problem grading code takes care
9691: of converting the bubbled letter information (now in %env) into a
9692: valid submission.
9693:
