1.424 albertel 5082: For this documentation:
5083:
5084: 'scanline' refers to the full line of characters
5085: from the file that we are parsing that represents one entire sheet
5086:
5087: 'bubble line' refers to the data
1.659 raeburn 5088: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5089:
5090:
1.659 raeburn 5091: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5092: into a course. When a user wants to grade, they select a
1.659 raeburn 5093: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5094: one of the predefined configurations for what each scanline looks
5095: like.
5096:
5097: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5098: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5099: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5100: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5101: invalid student/employee ID
1.424 albertel 5102:
5103: If the CODE option is used that determines the randomization of the
1.556 weissno 5104: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5105: username:domain.
5106:
5107: During the validation phase the instructor can choose to skip scanlines.
5108:
1.659 raeburn 5109: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5110:
5111: scantron_original_filename (unmodified original file)
5112: scantron_corrected_filename (file where the corrected information has replaced the original information)
5113: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5114:
5115: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5116: correction information that isn't representable in the bubblesheet
1.424 albertel 5117: file (see &scantron_getfile() for more information)
5118:
5119: After all scanlines are either valid, marked as valid or skipped, then
5120: foreach line foreach problem in the picked sequence, an ssi request is
5121: made that simulates a user submitting their selected letter(s) against
5122: the homework problem.

10352:
10353: Apache::grades
10354:
10355: =head1 SYNOPSIS
10356:
10357: Handles the viewing of grades.
10358:
10359: This is part of the LearningOnline Network with CAPA project
10360: described at http://www.lon-capa.org.
10361:
10362: =head1 OVERVIEW
10363:
10364: Do an ssi with retries:
10365: While I'd love to factor out this with the vesrion in lonprintout,
10366: 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
10367: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10368:
10369: At least the logic that drives this has been pulled out into loncommon.
10370:
10371:
10372:
10373: ssi_with_retries - Does the server side include of a resource.
10374: if the ssi call returns an error we'll retry it up to
10375: the number of times requested by the caller.
10376: If we still have a proble, no text is appended to the
10377: output and we set some global variables.
10378: to indicate to the caller an SSI error occurred.
10379: All of this is supposed to deal with the issues described
10380: in LonCAPA BZ 5631 see:
10381: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10382: by informing the user that this happened.
10383:
10384: Parameters:
10385: resource - The resource to include. This is passed directly, without
10386: interpretation to lonnet::ssi.
10387: form - The form hash parameters that guide the interpretation of the resource
10388:
10389: retries - Number of retries allowed before giving up completely.
10390: Returns:
10391: On success, returns the rendered resource identified by the resource parameter.
10392: Side Effects:
10393: The following global variables can be set:
10394: ssi_error - If an unrecoverable error occurred this becomes true.
10395: It is up to the caller to initialize this to false
10396: if desired.
10397: ssi_error_resource - If an unrecoverable error occurred, this is the value
10398: of the resource that could not be rendered by the ssi
10399: call.
10400: ssi_error_message - The error string fetched from the ssi response
10401: in the event of an error.

1.671 raeburn 10412: =head1 Routines to display previous version of a Task for a specific student
10413:
10414: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10415: can receive another opportunity. Access to tasks is slot-based. If a slot
10416: requires a proctor to check-in the student, a new version of the Task will
10417: be created when the student is checked in to the new opportunity.
10418:
10419: If a particular student has tried two or more versions of a particular task,
10420: the submission screen provides a user with vgr privileges (e.g., a Course
10421: Coordinator) the ability to display a previous version worked on by the
10422: student. By default, the current version is displayed. If a previous version
10423: has been selected for display, submission data are only shown that pertain
10424: to that particular version, and the interface to submit grades is not shown.
