5456:
1.424 albertel 5457: For this documentation:
5458:
5459: 'scanline' refers to the full line of characters
5460: from the file that we are parsing that represents one entire sheet
5461:
5462: 'bubble line' refers to the data
1.659 raeburn 5463: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5464:
5465:
1.659 raeburn 5466: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5467: into a course. When a user wants to grade, they select a
1.659 raeburn 5468: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5469: one of the predefined configurations for what each scanline looks
5470: like.
5471:
5472: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5473: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5474: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5475: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5476: invalid student/employee ID
1.424 albertel 5477:
5478: If the CODE option is used that determines the randomization of the
1.556 weissno 5479: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5480: username:domain.
5481:
5482: During the validation phase the instructor can choose to skip scanlines.
5483:
1.659 raeburn 5484: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5485:
5486: scantron_original_filename (unmodified original file)
5487: scantron_corrected_filename (file where the corrected information has replaced the original information)
5488: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5489:
5490: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5491: correction information that isn't representable in the bubblesheet
1.424 albertel 5492: file (see &scantron_getfile() for more information)
5493:
5494: After all scanlines are either valid, marked as valid or skipped, then
5495: foreach line foreach problem in the picked sequence, an ssi request is
5496: made that simulates a user submitting their selected letter(s) against
5497: the homework problem.

10778: =head1 NAME
10779:
10780: Apache::grades
10781:
10782: =head1 SYNOPSIS
10783:
10784: Handles the viewing of grades.
10785:
10786: This is part of the LearningOnline Network with CAPA project
10787: described at http://www.lon-capa.org.
10788:
10789: =head1 OVERVIEW
10790:
10791: Do an ssi with retries:
1.715 bisitz 10792: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10793: 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
10794: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10795:
10796: At least the logic that drives this has been pulled out into loncommon.
10797:
10798:
10799:
10800: ssi_with_retries - Does the server side include of a resource.
10801: if the ssi call returns an error we'll retry it up to
10802: the number of times requested by the caller.
1.715 bisitz 10803: If we still have a problem, no text is appended to the
1.531 jms 10804: output and we set some global variables.
10805: to indicate to the caller an SSI error occurred.
10806: All of this is supposed to deal with the issues described
1.715 bisitz 10807: in LON-CAPA BZ 5631 see:
1.531 jms 10808: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10809: by informing the user that this happened.
10810:
10811: Parameters:
10812: resource - The resource to include. This is passed directly, without
10813: interpretation to lonnet::ssi.
10814: form - The form hash parameters that guide the interpretation of the resource
10815:
10816: retries - Number of retries allowed before giving up completely.
10817: Returns:
10818: On success, returns the rendered resource identified by the resource parameter.
10819: Side Effects:
10820: The following global variables can be set:
10821: ssi_error - If an unrecoverable error occurred this becomes true.
10822: It is up to the caller to initialize this to false
10823: if desired.
10824: ssi_error_resource - If an unrecoverable error occurred, this is the value
10825: of the resource that could not be rendered by the ssi
10826: call.
10827: ssi_error_message - The error string fetched from the ssi response
10828: in the event of an error.
10829:

10840:
10841: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10842: can receive another opportunity. Access to tasks is slot-based. If a slot
10843: requires a proctor to check-in the student, a new version of the Task will
10844: be created when the student is checked in to the new opportunity.
10845:
10846: If a particular student has tried two or more versions of a particular task,
10847: the submission screen provides a user with vgr privileges (e.g., a Course
10848: Coordinator) the ability to display a previous version worked on by the
10849: student. By default, the current version is displayed. If a previous version
10850: has been selected for display, submission data are only shown that pertain
