5553:
1.424 albertel 5554: For this documentation:
5555:
5556: 'scanline' refers to the full line of characters
5557: from the file that we are parsing that represents one entire sheet
5558:
5559: 'bubble line' refers to the data
1.659 raeburn 5560: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5561:
5562:
1.659 raeburn 5563: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5564: into a course. When a user wants to grade, they select a
1.659 raeburn 5565: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5566: one of the predefined configurations for what each scanline looks
5567: like.
5568:
5569: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5570: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5571: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5572: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5573: invalid student/employee ID
1.424 albertel 5574:
5575: If the CODE option is used that determines the randomization of the
1.556 weissno 5576: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5577: username:domain.
5578:
5579: During the validation phase the instructor can choose to skip scanlines.
5580:
1.659 raeburn 5581: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5582:
5583: scantron_original_filename (unmodified original file)
5584: scantron_corrected_filename (file where the corrected information has replaced the original information)
5585: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5586:
5587: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5588: correction information that isn't representable in the bubblesheet
1.424 albertel 5589: file (see &scantron_getfile() for more information)
5590:
5591: After all scanlines are either valid, marked as valid or skipped, then
5592: foreach line foreach problem in the picked sequence, an ssi request is
5593: made that simulates a user submitting their selected letter(s) against
5594: the homework problem.

10876:
10877: Apache::grades
10878:
10879: =head1 SYNOPSIS
10880:
10881: Handles the viewing of grades.
10882:
10883: This is part of the LearningOnline Network with CAPA project
10884: described at http://www.lon-capa.org.
10885:
10886: =head1 OVERVIEW
10887:
10888: Do an ssi with retries:
1.715 bisitz 10889: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10890: 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
10891: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10892:
10893: At least the logic that drives this has been pulled out into loncommon.
10894:
10895:
10896:
10897: ssi_with_retries - Does the server side include of a resource.
10898: if the ssi call returns an error we'll retry it up to
10899: the number of times requested by the caller.
1.715 bisitz 10900: If we still have a problem, no text is appended to the
1.531 jms 10901: output and we set some global variables.
10902: to indicate to the caller an SSI error occurred.
10903: All of this is supposed to deal with the issues described
1.715 bisitz 10904: in LON-CAPA BZ 5631 see:
1.531 jms 10905: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10906: by informing the user that this happened.
10907:
10908: Parameters:
10909: resource - The resource to include. This is passed directly, without
10910: interpretation to lonnet::ssi.
10911: form - The form hash parameters that guide the interpretation of the resource
10912:
10913: retries - Number of retries allowed before giving up completely.
10914: Returns:
10915: On success, returns the rendered resource identified by the resource parameter.
10916: Side Effects:
10917: The following global variables can be set:
10918: ssi_error - If an unrecoverable error occurred this becomes true.
10919: It is up to the caller to initialize this to false
10920: if desired.
10921: ssi_error_resource - If an unrecoverable error occurred, this is the value
10922: of the resource that could not be rendered by the ssi
10923: call.
10924: ssi_error_message - The error string fetched from the ssi response
10925: in the event of an error.

10935:
1.671 raeburn 10936: =head1 Routines to display previous version of a Task for a specific student
10937:
10938: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10939: can receive another opportunity. Access to tasks is slot-based. If a slot
10940: requires a proctor to check-in the student, a new version of the Task will
10941: be created when the student is checked in to the new opportunity.
10942:
10943: If a particular student has tried two or more versions of a particular task,
10944: the submission screen provides a user with vgr privileges (e.g., a Course
10945: Coordinator) the ability to display a previous version worked on by the
10946: student. By default, the current version is displayed. If a previous version
10947: has been selected for display, submission data are only shown that pertain
10948: to that particular version, and the interface to submit grades is not shown.

10959:

10961:
10962: Side Effects: calls &show_problem() to print version of Task, with

10964:
10965: =item choose_task_version_form()
10966:
10967: Displays a web form used to select which version of a student's view of a

10969: content in existing pop-up, or replaces page in main window.
10970:

10976: breadcrumbs etc., are displayed
10977:
10978: Output: 4
10979: current - student's current version
10980: displayed - student's version being displayed
10981: result - scalar containing HTML for web form used to switch to
10982: a different version (or a link to close window, if pop-up).
10983: js - javascript for processing selection in versions web form
10984:

10992: current - student's current version number.
10993:
