5041:
1.424 albertel 5042: For this documentation:
5043:
5044: 'scanline' refers to the full line of characters
5045: from the file that we are parsing that represents one entire sheet
5046:
5047: 'bubble line' refers to the data
1.659 raeburn 5048: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5049:
5050:
1.659 raeburn 5051: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5052: into a course. When a user wants to grade, they select a
1.659 raeburn 5053: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5054: one of the predefined configurations for what each scanline looks
5055: like.
5056:
5057: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5058: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5059: because too light bubbling), 'double bubble' (each bubble line should
5060: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 5061: invalid student/employee ID
1.424 albertel 5062:
5063: If the CODE option is used that determines the randomization of the
1.556 weissno 5064: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5065: username:domain.
5066:
5067: During the validation phase the instructor can choose to skip scanlines.
5068:
1.659 raeburn 5069: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5070:
5071: scantron_original_filename (unmodified original file)
5072: scantron_corrected_filename (file where the corrected information has replaced the original information)
5073: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5074:
5075: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5076: correction information that isn't representable in the bubblesheet
1.424 albertel 5077: file (see &scantron_getfile() for more information)
5078:
5079: After all scanlines are either valid, marked as valid or skipped, then
5080: foreach line foreach problem in the picked sequence, an ssi request is
5081: made that simulates a user submitting their selected letter(s) against
5082: the homework problem.

10276: Apache::grades
10277:
10278: =head1 SYNOPSIS
10279:
10280: Handles the viewing of grades.
10281:
10282: This is part of the LearningOnline Network with CAPA project
10283: described at http://www.lon-capa.org.
10284:
10285: =head1 OVERVIEW
10286:
10287: Do an ssi with retries:
10288: While I'd love to factor out this with the vesrion in lonprintout,
10289: 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
10290: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10291:
10292: At least the logic that drives this has been pulled out into loncommon.
10293:
10294:
10295:
10296: ssi_with_retries - Does the server side include of a resource.
10297: if the ssi call returns an error we'll retry it up to
10298: the number of times requested by the caller.
10299: If we still have a proble, no text is appended to the
10300: output and we set some global variables.
10301: to indicate to the caller an SSI error occurred.
10302: All of this is supposed to deal with the issues described
10303: in LonCAPA BZ 5631 see:
10304: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10305: by informing the user that this happened.
10306:
10307: Parameters:
10308: resource - The resource to include. This is passed directly, without
10309: interpretation to lonnet::ssi.
10310: form - The form hash parameters that guide the interpretation of the resource
10311:
10312: retries - Number of retries allowed before giving up completely.
10313: Returns:
10314: On success, returns the rendered resource identified by the resource parameter.
10315: Side Effects:
10316: The following global variables can be set:
10317: ssi_error - If an unrecoverable error occurred this becomes true.
10318: It is up to the caller to initialize this to false
10319: if desired.
10320: ssi_error_resource - If an unrecoverable error occurred, this is the value
10321: of the resource that could not be rendered by the ssi
10322: call.
10323: ssi_error_message - The error string fetched from the ssi response
10324: in the event of an error.

1.671 raeburn 10335: =head1 Routines to display previous version of a Task for a specific student
10336:
10337: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10338: can receive another opportunity. Access to tasks is slot-based. If a slot
10339: requires a proctor to check-in the student, a new version of the Task will
10340: be created when the student is checked in to the new opportunity.
10341:
10342: If a particular student has tried two or more versions of a particular task,
10343: the submission screen provides a user with vgr privileges (e.g., a Course
10344: Coordinator) the ability to display a previous version worked on by the
10345: student. By default, the current version is displayed. If a previous version
10346: has been selected for display, submission data are only shown that pertain
10347: to that particular version, and the interface to submit grades is not shown.
