1.424 albertel 5050: For this documentation:
5051:
5052: 'scanline' refers to the full line of characters
5053: from the file that we are parsing that represents one entire sheet
5054:
5055: 'bubble line' refers to the data
1.659 raeburn 5056: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5057:
5058:
1.659 raeburn 5059: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5060: into a course. When a user wants to grade, they select a
1.659 raeburn 5061: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5062: one of the predefined configurations for what each scanline looks
5063: like.
5064:
5065: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5066: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5067: because too light bubbling), 'double bubble' (each bubble line should
5068: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 5069: invalid student/employee ID
1.424 albertel 5070:
5071: If the CODE option is used that determines the randomization of the
1.556 weissno 5072: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5073: username:domain.
5074:
5075: During the validation phase the instructor can choose to skip scanlines.
5076:
1.659 raeburn 5077: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5078:
5079: scantron_original_filename (unmodified original file)
5080: scantron_corrected_filename (file where the corrected information has replaced the original information)
5081: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5082:
5083: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5084: correction information that isn't representable in the bubblesheet
1.424 albertel 5085: file (see &scantron_getfile() for more information)
5086:
5087: After all scanlines are either valid, marked as valid or skipped, then
5088: foreach line foreach problem in the picked sequence, an ssi request is
5089: made that simulates a user submitting their selected letter(s) against
5090: the homework problem.

10284: Apache::grades
10285:
10286: =head1 SYNOPSIS
10287:
10288: Handles the viewing of grades.
10289:
10290: This is part of the LearningOnline Network with CAPA project
10291: described at http://www.lon-capa.org.
10292:
10293: =head1 OVERVIEW
10294:
10295: Do an ssi with retries:
10296: While I'd love to factor out this with the vesrion in lonprintout,
10297: 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
10298: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10299:
10300: At least the logic that drives this has been pulled out into loncommon.
10301:
10302:
10303:
10304: ssi_with_retries - Does the server side include of a resource.
10305: if the ssi call returns an error we'll retry it up to
10306: the number of times requested by the caller.
10307: If we still have a proble, no text is appended to the
10308: output and we set some global variables.
10309: to indicate to the caller an SSI error occurred.
10310: All of this is supposed to deal with the issues described
10311: in LonCAPA BZ 5631 see:
10312: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10313: by informing the user that this happened.
10314:
10315: Parameters:
10316: resource - The resource to include. This is passed directly, without
10317: interpretation to lonnet::ssi.
10318: form - The form hash parameters that guide the interpretation of the resource
10319:
10320: retries - Number of retries allowed before giving up completely.
10321: Returns:
10322: On success, returns the rendered resource identified by the resource parameter.
10323: Side Effects:
10324: The following global variables can be set:
10325: ssi_error - If an unrecoverable error occurred this becomes true.
10326: It is up to the caller to initialize this to false
10327: if desired.
10328: ssi_error_resource - If an unrecoverable error occurred, this is the value
10329: of the resource that could not be rendered by the ssi
10330: call.
10331: ssi_error_message - The error string fetched from the ssi response
10332: in the event of an error.

1.671 raeburn 10343: =head1 Routines to display previous version of a Task for a specific student
10344:
10345: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10346: can receive another opportunity. Access to tasks is slot-based. If a slot
10347: requires a proctor to check-in the student, a new version of the Task will
10348: be created when the student is checked in to the new opportunity.
10349:
10350: If a particular student has tried two or more versions of a particular task,
10351: the submission screen provides a user with vgr privileges (e.g., a Course
10352: Coordinator) the ability to display a previous version worked on by the
10353: student. By default, the current version is displayed. If a previous version
10354: has been selected for display, submission data are only shown that pertain
10355: to that particular version, and the interface to submit grades is not shown.
