5086: =head1 Bubble sheet grading routines
5087:
5088: For this documentation:
5089:
5090: 'scanline' refers to the full line of characters
5091: from the file that we are parsing that represents one entire sheet
5092:
5093: 'bubble line' refers to the data
5094: representing the line of bubbles that are on the physical bubblesheet
5095:
5096:
5097: The overall process is that a scanned in bubblesheet data is uploaded
5098: into a course. When a user wants to grade, they select a
5099: sequence/folder of resources, a file of bubblesheet info, and pick
5100: one of the predefined configurations for what each scanline looks
5101: like.
5102:
5103: Next each scanline is checked for any errors of either 'missing
5104: bubbles' (it's an error because it may have been mis-scanned
5105: because too light bubbling), 'double bubble' (each bubble line should
5106: have no more than one letter picked), invalid or duplicated CODE,
5107: invalid student/employee ID
5108:
5109: If the CODE option is used that determines the randomization of the
5110: homework problems, either way the student/employee ID is looked up into a
5111: username:domain.
5112:
5113: During the validation phase the instructor can choose to skip scanlines.
5114:
5115: After the validation phase, there are now 3 bubblesheet files
5116:
5117: scantron_original_filename (unmodified original file)
5118: scantron_corrected_filename (file where the corrected information has replaced the original information)
5119: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5120:
5121: Also there is a separate hash nohist_scantrondata that contains extra
5122: correction information that isn't representable in the bubblesheet
5123: file (see &scantron_getfile() for more information)
5124:
5125: After all scanlines are either valid, marked as valid or skipped, then
5126: foreach line foreach problem in the picked sequence, an ssi request is
5127: made that simulates a user submitting their selected letter(s) against
5128: the homework problem.

10357: =head1 NAME
10358:
10359: Apache::grades
10360:
10361: =head1 SYNOPSIS
10362:
10363: Handles the viewing of grades.
10364:
10365: This is part of the LearningOnline Network with CAPA project
10366: described at http://www.lon-capa.org.
10367:
10368: =head1 OVERVIEW
10369:
10370: Do an ssi with retries:
10371: While I'd love to factor out this with the version in lonprintout,
10372: 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
10373: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10374:
10375: At least the logic that drives this has been pulled out into loncommon.
10376:
10377:
10378:
10379: ssi_with_retries - Does the server side include of a resource.
10380: if the ssi call returns an error we'll retry it up to
10381: the number of times requested by the caller.
10382: If we still have a problem, no text is appended to the
10383: output and we set some global variables.
10384: to indicate to the caller an SSI error occurred.
10385: All of this is supposed to deal with the issues described
10386: in LON-CAPA BZ 5631 see:
10387: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10388: by informing the user that this happened.
10389:
10390: Parameters:
10391: resource - The resource to include. This is passed directly, without
10392: interpretation to lonnet::ssi.
10393: form - The form hash parameters that guide the interpretation of the resource
10394:
10395: retries - Number of retries allowed before giving up completely.
10396: Returns:
10397: On success, returns the rendered resource identified by the resource parameter.
10398: Side Effects:
10399: The following global variables can be set:
10400: ssi_error - If an unrecoverable error occurred this becomes true.
10401: It is up to the caller to initialize this to false
10402: if desired.
10403: ssi_error_resource - If an unrecoverable error occurred, this is the value
10404: of the resource that could not be rendered by the ssi
10405: call.
10406: ssi_error_message - The error string fetched from the ssi response
10407: in the event of an error.

10414: =head1 SUBROUTINES
10415:
10416: =over
10417:
10418: =head1 Routines to display previous version of a Task for a specific student
10419:
10420: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10421: can receive another opportunity. Access to tasks is slot-based. If a slot
10422: requires a proctor to check-in the student, a new version of the Task will
10423: be created when the student is checked in to the new opportunity.
10424:
10425: If a particular student has tried two or more versions of a particular task,
10426: the submission screen provides a user with vgr privileges (e.g., a Course
10427: Coordinator) the ability to display a previous version worked on by the
10428: student. By default, the current version is displayed. If a previous version
10429: has been selected for display, submission data are only shown that pertain
10430: to that particular version, and the interface to submit grades is not shown.
10431:

10433:
