1.424 albertel 5108: For this documentation:
5109:
5110: 'scanline' refers to the full line of characters
5111: from the file that we are parsing that represents one entire sheet
5112:
5113: 'bubble line' refers to the data
1.659 raeburn 5114: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5115:
5116:
1.659 raeburn 5117: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5118: into a course. When a user wants to grade, they select a
1.659 raeburn 5119: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5120: one of the predefined configurations for what each scanline looks
5121: like.
5122:
5123: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5124: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5125: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5126: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5127: invalid student/employee ID
1.424 albertel 5128:
5129: If the CODE option is used that determines the randomization of the
1.556 weissno 5130: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5131: username:domain.
5132:
5133: During the validation phase the instructor can choose to skip scanlines.
5134:
1.659 raeburn 5135: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5136:
5137: scantron_original_filename (unmodified original file)
5138: scantron_corrected_filename (file where the corrected information has replaced the original information)
5139: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5140:
5141: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5142: correction information that isn't representable in the bubblesheet
1.424 albertel 5143: file (see &scantron_getfile() for more information)
5144:
5145: After all scanlines are either valid, marked as valid or skipped, then
5146: foreach line foreach problem in the picked sequence, an ssi request is
5147: made that simulates a user submitting their selected letter(s) against
5148: the homework problem.

10378:
10379: Apache::grades
10380:
10381: =head1 SYNOPSIS
10382:
10383: Handles the viewing of grades.
10384:
10385: This is part of the LearningOnline Network with CAPA project
10386: described at http://www.lon-capa.org.
10387:
10388: =head1 OVERVIEW
10389:
10390: Do an ssi with retries:
1.715 bisitz 10391: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10392: 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
10393: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10394:
10395: At least the logic that drives this has been pulled out into loncommon.
10396:
10397:
10398:
10399: ssi_with_retries - Does the server side include of a resource.
10400: if the ssi call returns an error we'll retry it up to
10401: the number of times requested by the caller.
1.715 bisitz 10402: If we still have a problem, no text is appended to the
1.531 jms 10403: output and we set some global variables.
10404: to indicate to the caller an SSI error occurred.
10405: All of this is supposed to deal with the issues described
1.715 bisitz 10406: in LON-CAPA BZ 5631 see:
1.531 jms 10407: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10408: by informing the user that this happened.
10409:
10410: Parameters:
10411: resource - The resource to include. This is passed directly, without
10412: interpretation to lonnet::ssi.
10413: form - The form hash parameters that guide the interpretation of the resource
10414:
10415: retries - Number of retries allowed before giving up completely.
10416: Returns:
10417: On success, returns the rendered resource identified by the resource parameter.
10418: Side Effects:
10419: The following global variables can be set:
10420: ssi_error - If an unrecoverable error occurred this becomes true.
10421: It is up to the caller to initialize this to false
10422: if desired.
10423: ssi_error_resource - If an unrecoverable error occurred, this is the value
10424: of the resource that could not be rendered by the ssi
10425: call.
10426: ssi_error_message - The error string fetched from the ssi response
10427: in the event of an error.

1.671 raeburn 10438: =head1 Routines to display previous version of a Task for a specific student
10439:
10440: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10441: can receive another opportunity. Access to tasks is slot-based. If a slot
10442: requires a proctor to check-in the student, a new version of the Task will
10443: be created when the student is checked in to the new opportunity.
10444:
10445: If a particular student has tried two or more versions of a particular task,
10446: the submission screen provides a user with vgr privileges (e.g., a Course
10447: Coordinator) the ability to display a previous version worked on by the
10448: student. By default, the current version is displayed. If a previous version
10449: has been selected for display, submission data are only shown that pertain
10450: to that particular version, and the interface to submit grades is not shown.
