5326:
1.424 albertel 5327: For this documentation:
5328:
5329: 'scanline' refers to the full line of characters
5330: from the file that we are parsing that represents one entire sheet
5331:
5332: 'bubble line' refers to the data
1.659 raeburn 5333: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5334:
5335:
1.659 raeburn 5336: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5337: into a course. When a user wants to grade, they select a
1.659 raeburn 5338: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5339: one of the predefined configurations for what each scanline looks
5340: like.
5341:
5342: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5343: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5344: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5345: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5346: invalid student/employee ID
1.424 albertel 5347:
5348: If the CODE option is used that determines the randomization of the
1.556 weissno 5349: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5350: username:domain.
5351:
5352: During the validation phase the instructor can choose to skip scanlines.
5353:
1.659 raeburn 5354: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5355:
5356: scantron_original_filename (unmodified original file)
5357: scantron_corrected_filename (file where the corrected information has replaced the original information)
5358: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5359:
5360: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5361: correction information that isn't representable in the bubblesheet
1.424 albertel 5362: file (see &scantron_getfile() for more information)
5363:
5364: After all scanlines are either valid, marked as valid or skipped, then
5365: foreach line foreach problem in the picked sequence, an ssi request is
5366: made that simulates a user submitting their selected letter(s) against
5367: the homework problem.

10627:
10628: Apache::grades
10629:
10630: =head1 SYNOPSIS
10631:
10632: Handles the viewing of grades.
10633:
10634: This is part of the LearningOnline Network with CAPA project
10635: described at http://www.lon-capa.org.
10636:
10637: =head1 OVERVIEW
10638:
10639: Do an ssi with retries:
1.715 bisitz 10640: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10641: 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
10642: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10643:
10644: At least the logic that drives this has been pulled out into loncommon.
10645:
10646:
10647:
10648: ssi_with_retries - Does the server side include of a resource.
10649: if the ssi call returns an error we'll retry it up to
10650: the number of times requested by the caller.
1.715 bisitz 10651: If we still have a problem, no text is appended to the
1.531 jms 10652: output and we set some global variables.
10653: to indicate to the caller an SSI error occurred.
10654: All of this is supposed to deal with the issues described
1.715 bisitz 10655: in LON-CAPA BZ 5631 see:
1.531 jms 10656: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10657: by informing the user that this happened.
10658:
10659: Parameters:
10660: resource - The resource to include. This is passed directly, without
10661: interpretation to lonnet::ssi.
10662: form - The form hash parameters that guide the interpretation of the resource
10663:
10664: retries - Number of retries allowed before giving up completely.
10665: Returns:
10666: On success, returns the rendered resource identified by the resource parameter.
10667: Side Effects:
10668: The following global variables can be set:
10669: ssi_error - If an unrecoverable error occurred this becomes true.
10670: It is up to the caller to initialize this to false
10671: if desired.
10672: ssi_error_resource - If an unrecoverable error occurred, this is the value
10673: of the resource that could not be rendered by the ssi
10674: call.
10675: ssi_error_message - The error string fetched from the ssi response
10676: in the event of an error.

1.671 raeburn 10687: =head1 Routines to display previous version of a Task for a specific student
10688:
10689: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10690: can receive another opportunity. Access to tasks is slot-based. If a slot
10691: requires a proctor to check-in the student, a new version of the Task will
10692: be created when the student is checked in to the new opportunity.
10693:
10694: If a particular student has tried two or more versions of a particular task,
10695: the submission screen provides a user with vgr privileges (e.g., a Course
10696: Coordinator) the ability to display a previous version worked on by the
10697: student. By default, the current version is displayed. If a previous version
10698: has been selected for display, submission data are only shown that pertain
10699: to that particular version, and the interface to submit grades is not shown.
