7050:
1.424 albertel 7051: For this documentation:
7052:
7053: 'scanline' refers to the full line of characters
7054: from the file that we are parsing that represents one entire sheet
7055:
7056: 'bubble line' refers to the data
1.659 raeburn 7057: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 7058:
7059:
1.659 raeburn 7060: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 7061: into a course. When a user wants to grade, they select a
1.659 raeburn 7062: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 7063: one of the predefined configurations for what each scanline looks
7064: like.
7065:
7066: Next each scanline is checked for any errors of either 'missing
1.435 foxr 7067: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 7068: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 7069: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 7070: invalid student/employee ID
1.424 albertel 7071:
7072: If the CODE option is used that determines the randomization of the
1.556 weissno 7073: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 7074: username:domain.
7075:
7076: During the validation phase the instructor can choose to skip scanlines.
7077:
1.659 raeburn 7078: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 7079:
7080: scantron_original_filename (unmodified original file)
7081: scantron_corrected_filename (file where the corrected information has replaced the original information)
7082: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
7083:
7084: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 7085: correction information that isn't representable in the bubblesheet
1.424 albertel 7086: file (see &scantron_getfile() for more information)
7087:
7088: After all scanlines are either valid, marked as valid or skipped, then
7089: foreach line foreach problem in the picked sequence, an ssi request is
7090: made that simulates a user submitting their selected letter(s) against
7091: the homework problem.

13104:
13105: =head1 SYNOPSIS
13106:
13107: Handles the viewing of grades.
13108:
13109: This is part of the LearningOnline Network with CAPA project
13110: described at http://www.lon-capa.org.
13111:
13112: =head1 OVERVIEW
13113:
13114: Do an ssi with retries:
1.715 bisitz 13115: While I'd love to factor out this with the version in lonprintout,
1.531 jms 13116: 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
13117: I'm not quite ready to invent (e.g. an ssi_with_retry object).
13118:
13119: At least the logic that drives this has been pulled out into loncommon.
13120:
13121:
13122:
13123: ssi_with_retries - Does the server side include of a resource.
13124: if the ssi call returns an error we'll retry it up to
13125: the number of times requested by the caller.
1.715 bisitz 13126: If we still have a problem, no text is appended to the
1.531 jms 13127: output and we set some global variables.
13128: to indicate to the caller an SSI error occurred.
13129: All of this is supposed to deal with the issues described
1.715 bisitz 13130: in LON-CAPA BZ 5631 see:
1.531 jms 13131: http://bugs.lon-capa.org/show_bug.cgi?id=5631
13132: by informing the user that this happened.
13133:
13134: Parameters:
13135: resource - The resource to include. This is passed directly, without
13136: interpretation to lonnet::ssi.
13137: form - The form hash parameters that guide the interpretation of the resource
13138:
13139: retries - Number of retries allowed before giving up completely.
13140: Returns:
13141: On success, returns the rendered resource identified by the resource parameter.
13142: Side Effects:
13143: The following global variables can be set:
13144: ssi_error - If an unrecoverable error occurred this becomes true.
13145: It is up to the caller to initialize this to false
13146: if desired.
13147: ssi_error_resource - If an unrecoverable error occurred, this is the value
13148: of the resource that could not be rendered by the ssi
13149: call.
13150: ssi_error_message - The error string fetched from the ssi response
13151: in the event of an error.

1.671 raeburn 13162: =head1 Routines to display previous version of a Task for a specific student
13163:
13164: Tasks are graded pass/fail. Students who have yet to pass a particular Task
13165: can receive another opportunity. Access to tasks is slot-based. If a slot
13166: requires a proctor to check-in the student, a new version of the Task will
13167: be created when the student is checked in to the new opportunity.
13168:
13169: If a particular student has tried two or more versions of a particular task,
13170: the submission screen provides a user with vgr privileges (e.g., a Course
13171: Coordinator) the ability to display a previous version worked on by the
13172: student. By default, the current version is displayed. If a previous version
13173: has been selected for display, submission data are only shown that pertain
13174: to that particular version, and the interface to submit grades is not shown.
