1.424 albertel 5035: For this documentation:
5036:
5037: 'scanline' refers to the full line of characters
5038: from the file that we are parsing that represents one entire sheet
5039:
5040: 'bubble line' refers to the data
1.659 raeburn 5041: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5042:
5043:
1.659 raeburn 5044: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5045: into a course. When a user wants to grade, they select a
1.659 raeburn 5046: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5047: one of the predefined configurations for what each scanline looks
5048: like.
5049:
5050: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5051: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5052: because too light bubbling), 'double bubble' (each bubble line should
5053: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 5054: invalid student/employee ID
1.424 albertel 5055:
5056: If the CODE option is used that determines the randomization of the
1.556 weissno 5057: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5058: username:domain.
5059:
5060: During the validation phase the instructor can choose to skip scanlines.
5061:
1.659 raeburn 5062: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5063:
5064: scantron_original_filename (unmodified original file)
5065: scantron_corrected_filename (file where the corrected information has replaced the original information)
5066: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5067:
5068: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5069: correction information that isn't representable in the bubblesheet
1.424 albertel 5070: file (see &scantron_getfile() for more information)
5071:
5072: After all scanlines are either valid, marked as valid or skipped, then
5073: foreach line foreach problem in the picked sequence, an ssi request is
5074: made that simulates a user submitting their selected letter(s) against
5075: the homework problem.

9834: =head1 NAME
9835:
9836: Apache::grades
9837:
9838: =head1 SYNOPSIS
9839:
9840: Handles the viewing of grades.
9841:
9842: This is part of the LearningOnline Network with CAPA project
9843: described at http://www.lon-capa.org.
9844:
9845: =head1 OVERVIEW
9846:
9847: Do an ssi with retries:
9848: While I'd love to factor out this with the vesrion in lonprintout,
9849: 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
9850: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9851:
9852: At least the logic that drives this has been pulled out into loncommon.
9853:
9854:
9855:
9856: ssi_with_retries - Does the server side include of a resource.
9857: if the ssi call returns an error we'll retry it up to
9858: the number of times requested by the caller.
9859: If we still have a proble, no text is appended to the
9860: output and we set some global variables.
9861: to indicate to the caller an SSI error occurred.
9862: All of this is supposed to deal with the issues described
9863: in LonCAPA BZ 5631 see:
9864: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9865: by informing the user that this happened.
9866:
9867: Parameters:
9868: resource - The resource to include. This is passed directly, without
9869: interpretation to lonnet::ssi.
9870: form - The form hash parameters that guide the interpretation of the resource
9871:
9872: retries - Number of retries allowed before giving up completely.
9873: Returns:
9874: On success, returns the rendered resource identified by the resource parameter.
9875: Side Effects:
9876: The following global variables can be set:
9877: ssi_error - If an unrecoverable error occurred this becomes true.
9878: It is up to the caller to initialize this to false
9879: if desired.
9880: ssi_error_resource - If an unrecoverable error occurred, this is the value
9881: of the resource that could not be rendered by the ssi
9882: call.
9883: ssi_error_message - The error string fetched from the ssi response
9884: in the event of an error.

1.671 raeburn 9895: =head1 Routines to display previous version of a Task for a specific student
9896:
9897: Tasks are graded pass/fail. Students who have yet to pass a particular Task
9898: can receive another opportunity. Access to tasks is slot-based. If a slot
9899: requires a proctor to check-in the student, a new version of the Task will
9900: be created when the student is checked in to the new opportunity.
9901:
9902: If a particular student has tried two or more versions of a particular task,
9903: the submission screen provides a user with vgr privileges (e.g., a Course
9904: Coordinator) the ability to display a previous version worked on by the
9905: student. By default, the current version is displayed. If a previous version
9906: has been selected for display, submission data are only shown that pertain
9907: to that particular version, and the interface to submit grades is not shown.

9918:

9920:

9923:

9928: content in existing pop-up, or replaces page in main window.
9929:
9930: Inputs: 4
9931: symb - unique symb for current instance of resource
9932: uname - username of student
9933: udom - domain of student
9934: nomenu - 1 if display is in a pop-up window, and hence no menu
9935: breadcrumbs etc., are displayed
9936:
9937: Output: 4
9938: current - student's current version
9939: displayed - student's version being displayed
9940: result - scalar containing HTML for web form used to switch to
9941: a different version (or a link to close window, if pop-up).
9942: js - javascript for processing selection in versions web form
9943:
9944: Side Effects: None.

9946: =item previous_display_javascript()
9947:
9948: Inputs: 2
