1.424 albertel 5040: For this documentation:
5041:
5042: 'scanline' refers to the full line of characters
5043: from the file that we are parsing that represents one entire sheet
5044:
5045: 'bubble line' refers to the data
1.659 raeburn 5046: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5047:
5048:
1.659 raeburn 5049: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5050: into a course. When a user wants to grade, they select a
1.659 raeburn 5051: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5052: one of the predefined configurations for what each scanline looks
5053: like.
5054:
5055: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5056: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5057: because too light bubbling), 'double bubble' (each bubble line should
5058: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 5059: invalid student/employee ID
1.424 albertel 5060:
5061: If the CODE option is used that determines the randomization of the
1.556 weissno 5062: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5063: username:domain.
5064:
5065: During the validation phase the instructor can choose to skip scanlines.
5066:
1.659 raeburn 5067: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5068:
5069: scantron_original_filename (unmodified original file)
5070: scantron_corrected_filename (file where the corrected information has replaced the original information)
5071: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5072:
5073: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5074: correction information that isn't representable in the bubblesheet
1.424 albertel 5075: file (see &scantron_getfile() for more information)
5076:
5077: After all scanlines are either valid, marked as valid or skipped, then
5078: foreach line foreach problem in the picked sequence, an ssi request is
5079: made that simulates a user submitting their selected letter(s) against
5080: the homework problem.

9854: =head1 NAME
9855:
9856: Apache::grades
9857:
9858: =head1 SYNOPSIS
9859:
9860: Handles the viewing of grades.
9861:
9862: This is part of the LearningOnline Network with CAPA project
9863: described at http://www.lon-capa.org.
9864:
9865: =head1 OVERVIEW
9866:
9867: Do an ssi with retries:
9868: While I'd love to factor out this with the vesrion in lonprintout,
9869: 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
9870: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9871:
9872: At least the logic that drives this has been pulled out into loncommon.
9873:
9874:
9875:
9876: ssi_with_retries - Does the server side include of a resource.
9877: if the ssi call returns an error we'll retry it up to
9878: the number of times requested by the caller.
9879: If we still have a proble, no text is appended to the
9880: output and we set some global variables.
9881: to indicate to the caller an SSI error occurred.
9882: All of this is supposed to deal with the issues described
9883: in LonCAPA BZ 5631 see:
9884: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9885: by informing the user that this happened.
9886:
9887: Parameters:
9888: resource - The resource to include. This is passed directly, without
9889: interpretation to lonnet::ssi.
9890: form - The form hash parameters that guide the interpretation of the resource
9891:
9892: retries - Number of retries allowed before giving up completely.
9893: Returns:
9894: On success, returns the rendered resource identified by the resource parameter.
9895: Side Effects:
9896: The following global variables can be set:
9897: ssi_error - If an unrecoverable error occurred this becomes true.
9898: It is up to the caller to initialize this to false
9899: if desired.
9900: ssi_error_resource - If an unrecoverable error occurred, this is the value
9901: of the resource that could not be rendered by the ssi
9902: call.
9903: ssi_error_message - The error string fetched from the ssi response
9904: in the event of an error.

1.671 raeburn 9915: =head1 Routines to display previous version of a Task for a specific student
9916:
9917: Tasks are graded pass/fail. Students who have yet to pass a particular Task
9918: can receive another opportunity. Access to tasks is slot-based. If a slot
9919: requires a proctor to check-in the student, a new version of the Task will
9920: be created when the student is checked in to the new opportunity.
9921:
9922: If a particular student has tried two or more versions of a particular task,
9923: the submission screen provides a user with vgr privileges (e.g., a Course
9924: Coordinator) the ability to display a previous version worked on by the
9925: student. By default, the current version is displayed. If a previous version
9926: has been selected for display, submission data are only shown that pertain
9927: to that particular version, and the interface to submit grades is not shown.

9949:

9955: breadcrumbs etc., are displayed
9956:
9957: Output: 4
9958: current - student's current version
9959: displayed - student's version being displayed
9960: result - scalar containing HTML for web form used to switch to
9961: a different version (or a link to close window, if pop-up).
9962: js - javascript for processing selection in versions web form
9963:
9964: Side Effects: None.

9967:
9968: Inputs: 2
