5555:
1.424 albertel 5556: For this documentation:
5557:
5558: 'scanline' refers to the full line of characters
5559: from the file that we are parsing that represents one entire sheet
5560:
5561: 'bubble line' refers to the data
1.659 raeburn 5562: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5563:
5564:
1.659 raeburn 5565: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5566: into a course. When a user wants to grade, they select a
1.659 raeburn 5567: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5568: one of the predefined configurations for what each scanline looks
5569: like.
5570:
5571: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5572: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5573: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5574: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5575: invalid student/employee ID
1.424 albertel 5576:
5577: If the CODE option is used that determines the randomization of the
1.556 weissno 5578: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5579: username:domain.
5580:
5581: During the validation phase the instructor can choose to skip scanlines.
5582:
1.659 raeburn 5583: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5584:
5585: scantron_original_filename (unmodified original file)
5586: scantron_corrected_filename (file where the corrected information has replaced the original information)
5587: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5588:
5589: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5590: correction information that isn't representable in the bubblesheet
1.424 albertel 5591: file (see &scantron_getfile() for more information)
5592:
5593: After all scanlines are either valid, marked as valid or skipped, then
5594: foreach line foreach problem in the picked sequence, an ssi request is
5595: made that simulates a user submitting their selected letter(s) against
5596: the homework problem.

10877: =head1 NAME
10878:
10879: Apache::grades
10880:
10881: =head1 SYNOPSIS
10882:
10883: Handles the viewing of grades.
10884:
10885: This is part of the LearningOnline Network with CAPA project
10886: described at http://www.lon-capa.org.
10887:
10888: =head1 OVERVIEW
10889:
10890: Do an ssi with retries:
1.715 bisitz 10891: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10892: 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
10893: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10894:
10895: At least the logic that drives this has been pulled out into loncommon.
10896:
10897:
10898:
10899: ssi_with_retries - Does the server side include of a resource.
10900: if the ssi call returns an error we'll retry it up to
10901: the number of times requested by the caller.
1.715 bisitz 10902: If we still have a problem, no text is appended to the
1.531 jms 10903: output and we set some global variables.
10904: to indicate to the caller an SSI error occurred.
10905: All of this is supposed to deal with the issues described
1.715 bisitz 10906: in LON-CAPA BZ 5631 see:
1.531 jms 10907: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10908: by informing the user that this happened.
10909:
10910: Parameters:
10911: resource - The resource to include. This is passed directly, without
10912: interpretation to lonnet::ssi.
10913: form - The form hash parameters that guide the interpretation of the resource
10914:
10915: retries - Number of retries allowed before giving up completely.
10916: Returns:
10917: On success, returns the rendered resource identified by the resource parameter.
10918: Side Effects:
10919: The following global variables can be set:
10920: ssi_error - If an unrecoverable error occurred this becomes true.
10921: It is up to the caller to initialize this to false
10922: if desired.
10923: ssi_error_resource - If an unrecoverable error occurred, this is the value
10924: of the resource that could not be rendered by the ssi
10925: call.
10926: ssi_error_message - The error string fetched from the ssi response
10927: in the event of an error.

10937:
1.671 raeburn 10938: =head1 Routines to display previous version of a Task for a specific student
10939:
10940: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10941: can receive another opportunity. Access to tasks is slot-based. If a slot
10942: requires a proctor to check-in the student, a new version of the Task will
10943: be created when the student is checked in to the new opportunity.
10944:
10945: If a particular student has tried two or more versions of a particular task,
10946: the submission screen provides a user with vgr privileges (e.g., a Course
10947: Coordinator) the ability to display a previous version worked on by the
10948: student. By default, the current version is displayed. If a previous version
10949: has been selected for display, submission data are only shown that pertain
10950: to that particular version, and the interface to submit grades is not shown.

10961:

10963:
10964: Side Effects: calls &show_problem() to print version of Task, with

10966:
10967: =item choose_task_version_form()
10968:
10969: Displays a web form used to select which version of a student's view of a

10971: content in existing pop-up, or replaces page in main window.
10972:
10973: Inputs: 4
10974: symb - unique symb for current instance of resource

10978: breadcrumbs etc., are displayed
10979:
10980: Output: 4
10981: current - student's current version
10982: displayed - student's version being displayed
10983: result - scalar containing HTML for web form used to switch to
10984: a different version (or a link to close window, if pop-up).
10985: js - javascript for processing selection in versions web form
10986:

10994: current - student's current version number.
10995:
