1.424 albertel 5116: For this documentation:
5117:
5118: 'scanline' refers to the full line of characters
5119: from the file that we are parsing that represents one entire sheet
5120:
5121: 'bubble line' refers to the data
1.659 raeburn 5122: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5123:
5124:
1.659 raeburn 5125: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5126: into a course. When a user wants to grade, they select a
1.659 raeburn 5127: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5128: one of the predefined configurations for what each scanline looks
5129: like.
5130:
5131: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5132: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5133: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5134: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5135: invalid student/employee ID
1.424 albertel 5136:
5137: If the CODE option is used that determines the randomization of the
1.556 weissno 5138: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5139: username:domain.
5140:
5141: During the validation phase the instructor can choose to skip scanlines.
5142:
1.659 raeburn 5143: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5144:
5145: scantron_original_filename (unmodified original file)
5146: scantron_corrected_filename (file where the corrected information has replaced the original information)
5147: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5148:
5149: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5150: correction information that isn't representable in the bubblesheet
1.424 albertel 5151: file (see &scantron_getfile() for more information)
5152:
5153: After all scanlines are either valid, marked as valid or skipped, then
5154: foreach line foreach problem in the picked sequence, an ssi request is
5155: made that simulates a user submitting their selected letter(s) against
5156: the homework problem.

10397:
10398: Apache::grades
10399:
10400: =head1 SYNOPSIS
10401:
10402: Handles the viewing of grades.
10403:
10404: This is part of the LearningOnline Network with CAPA project
10405: described at http://www.lon-capa.org.
10406:
10407: =head1 OVERVIEW
10408:
10409: Do an ssi with retries:
1.715 bisitz 10410: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10411: 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
10412: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10413:
10414: At least the logic that drives this has been pulled out into loncommon.
10415:
10416:
10417:
10418: ssi_with_retries - Does the server side include of a resource.
10419: if the ssi call returns an error we'll retry it up to
10420: the number of times requested by the caller.
1.715 bisitz 10421: If we still have a problem, no text is appended to the
1.531 jms 10422: output and we set some global variables.
10423: to indicate to the caller an SSI error occurred.
10424: All of this is supposed to deal with the issues described
1.715 bisitz 10425: in LON-CAPA BZ 5631 see:
1.531 jms 10426: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10427: by informing the user that this happened.
10428:
10429: Parameters:
10430: resource - The resource to include. This is passed directly, without
10431: interpretation to lonnet::ssi.
10432: form - The form hash parameters that guide the interpretation of the resource
10433:
10434: retries - Number of retries allowed before giving up completely.
10435: Returns:
10436: On success, returns the rendered resource identified by the resource parameter.
10437: Side Effects:
10438: The following global variables can be set:
10439: ssi_error - If an unrecoverable error occurred this becomes true.
10440: It is up to the caller to initialize this to false
10441: if desired.
10442: ssi_error_resource - If an unrecoverable error occurred, this is the value
10443: of the resource that could not be rendered by the ssi
10444: call.
10445: ssi_error_message - The error string fetched from the ssi response
10446: in the event of an error.

10458:
10459: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10460: can receive another opportunity. Access to tasks is slot-based. If a slot
10461: requires a proctor to check-in the student, a new version of the Task will
10462: be created when the student is checked in to the new opportunity.
10463:
10464: If a particular student has tried two or more versions of a particular task,
10465: the submission screen provides a user with vgr privileges (e.g., a Course
10466: Coordinator) the ability to display a previous version worked on by the
10467: student. By default, the current version is displayed. If a previous version
10468: has been selected for display, submission data are only shown that pertain
10469: to that particular version, and the interface to submit grades is not shown.
