5438:
1.424 albertel 5439: For this documentation:
5440:
5441: 'scanline' refers to the full line of characters
5442: from the file that we are parsing that represents one entire sheet
5443:
5444: 'bubble line' refers to the data
1.659 raeburn 5445: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5446:
5447:
1.659 raeburn 5448: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5449: into a course. When a user wants to grade, they select a
1.659 raeburn 5450: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5451: one of the predefined configurations for what each scanline looks
5452: like.
5453:
5454: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5455: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5456: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5457: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5458: invalid student/employee ID
1.424 albertel 5459:
5460: If the CODE option is used that determines the randomization of the
1.556 weissno 5461: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5462: username:domain.
5463:
5464: During the validation phase the instructor can choose to skip scanlines.
5465:
1.659 raeburn 5466: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5467:
5468: scantron_original_filename (unmodified original file)
5469: scantron_corrected_filename (file where the corrected information has replaced the original information)
5470: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5471:
5472: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5473: correction information that isn't representable in the bubblesheet
1.424 albertel 5474: file (see &scantron_getfile() for more information)
5475:
5476: After all scanlines are either valid, marked as valid or skipped, then
5477: foreach line foreach problem in the picked sequence, an ssi request is
5478: made that simulates a user submitting their selected letter(s) against
5479: the homework problem.

10761:
10762: Apache::grades
10763:
10764: =head1 SYNOPSIS
10765:
10766: Handles the viewing of grades.
10767:
10768: This is part of the LearningOnline Network with CAPA project
10769: described at http://www.lon-capa.org.
10770:
10771: =head1 OVERVIEW
10772:
10773: Do an ssi with retries:
1.715 bisitz 10774: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10775: 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
10776: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10777:
10778: At least the logic that drives this has been pulled out into loncommon.
10779:
10780:
10781:
10782: ssi_with_retries - Does the server side include of a resource.
10783: if the ssi call returns an error we'll retry it up to
10784: the number of times requested by the caller.
1.715 bisitz 10785: If we still have a problem, no text is appended to the
1.531 jms 10786: output and we set some global variables.
10787: to indicate to the caller an SSI error occurred.
10788: All of this is supposed to deal with the issues described
1.715 bisitz 10789: in LON-CAPA BZ 5631 see:
1.531 jms 10790: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10791: by informing the user that this happened.
10792:
10793: Parameters:
10794: resource - The resource to include. This is passed directly, without
10795: interpretation to lonnet::ssi.
10796: form - The form hash parameters that guide the interpretation of the resource
10797:
10798: retries - Number of retries allowed before giving up completely.
10799: Returns:
10800: On success, returns the rendered resource identified by the resource parameter.
10801: Side Effects:
10802: The following global variables can be set:
10803: ssi_error - If an unrecoverable error occurred this becomes true.
10804: It is up to the caller to initialize this to false
10805: if desired.
10806: ssi_error_resource - If an unrecoverable error occurred, this is the value
10807: of the resource that could not be rendered by the ssi
10808: call.
10809: ssi_error_message - The error string fetched from the ssi response
10810: in the event of an error.

10820:
1.671 raeburn 10821: =head1 Routines to display previous version of a Task for a specific student
10822:
10823: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10824: can receive another opportunity. Access to tasks is slot-based. If a slot
10825: requires a proctor to check-in the student, a new version of the Task will
10826: be created when the student is checked in to the new opportunity.
10827:
10828: If a particular student has tried two or more versions of a particular task,
10829: the submission screen provides a user with vgr privileges (e.g., a Course
10830: Coordinator) the ability to display a previous version worked on by the
10831: student. By default, the current version is displayed. If a previous version
10832: has been selected for display, submission data are only shown that pertain
10833: to that particular version, and the interface to submit grades is not shown.
