1.424 albertel 5119: For this documentation:
5120:
5121: 'scanline' refers to the full line of characters
5122: from the file that we are parsing that represents one entire sheet
5123:
5124: 'bubble line' refers to the data
1.659 raeburn 5125: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5126:
5127:
1.659 raeburn 5128: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5129: into a course. When a user wants to grade, they select a
1.659 raeburn 5130: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5131: one of the predefined configurations for what each scanline looks
5132: like.
5133:
5134: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5135: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5136: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5137: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5138: invalid student/employee ID
1.424 albertel 5139:
5140: If the CODE option is used that determines the randomization of the
1.556 weissno 5141: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5142: username:domain.
5143:
5144: During the validation phase the instructor can choose to skip scanlines.
5145:
1.659 raeburn 5146: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5147:
5148: scantron_original_filename (unmodified original file)
5149: scantron_corrected_filename (file where the corrected information has replaced the original information)
5150: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5151:
5152: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5153: correction information that isn't representable in the bubblesheet
1.424 albertel 5154: file (see &scantron_getfile() for more information)
5155:
5156: After all scanlines are either valid, marked as valid or skipped, then
5157: foreach line foreach problem in the picked sequence, an ssi request is
5158: made that simulates a user submitting their selected letter(s) against
5159: the homework problem.

10390: Apache::grades
10391:
10392: =head1 SYNOPSIS
10393:
10394: Handles the viewing of grades.
10395:
10396: This is part of the LearningOnline Network with CAPA project
10397: described at http://www.lon-capa.org.
10398:
10399: =head1 OVERVIEW
10400:
10401: Do an ssi with retries:
1.715 bisitz 10402: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10403: 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
10404: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10405:
10406: At least the logic that drives this has been pulled out into loncommon.
10407:
10408:
10409:
10410: ssi_with_retries - Does the server side include of a resource.
10411: if the ssi call returns an error we'll retry it up to
10412: the number of times requested by the caller.
1.715 bisitz 10413: If we still have a problem, no text is appended to the
1.531 jms 10414: output and we set some global variables.
10415: to indicate to the caller an SSI error occurred.
10416: All of this is supposed to deal with the issues described
1.715 bisitz 10417: in LON-CAPA BZ 5631 see:
1.531 jms 10418: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10419: by informing the user that this happened.
10420:
10421: Parameters:
10422: resource - The resource to include. This is passed directly, without
10423: interpretation to lonnet::ssi.
10424: form - The form hash parameters that guide the interpretation of the resource
10425:
10426: retries - Number of retries allowed before giving up completely.
10427: Returns:
10428: On success, returns the rendered resource identified by the resource parameter.
10429: Side Effects:
10430: The following global variables can be set:
10431: ssi_error - If an unrecoverable error occurred this becomes true.
10432: It is up to the caller to initialize this to false
10433: if desired.
10434: ssi_error_resource - If an unrecoverable error occurred, this is the value
10435: of the resource that could not be rendered by the ssi
10436: call.
10437: ssi_error_message - The error string fetched from the ssi response
10438: in the event of an error.

1.671 raeburn 10449: =head1 Routines to display previous version of a Task for a specific student
10450:
10451: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10452: can receive another opportunity. Access to tasks is slot-based. If a slot
10453: requires a proctor to check-in the student, a new version of the Task will
10454: be created when the student is checked in to the new opportunity.
10455:
10456: If a particular student has tried two or more versions of a particular task,
10457: the submission screen provides a user with vgr privileges (e.g., a Course
10458: Coordinator) the ability to display a previous version worked on by the
10459: student. By default, the current version is displayed. If a previous version
10460: has been selected for display, submission data are only shown that pertain
10461: to that particular version, and the interface to submit grades is not shown.
