5554:
1.424 albertel 5555: For this documentation:
5556:
5557: 'scanline' refers to the full line of characters
5558: from the file that we are parsing that represents one entire sheet
5559:
5560: 'bubble line' refers to the data
1.659 raeburn 5561: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5562:
5563:
1.659 raeburn 5564: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5565: into a course. When a user wants to grade, they select a
1.659 raeburn 5566: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5567: one of the predefined configurations for what each scanline looks
5568: like.
5569:
5570: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5571: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5572: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5573: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5574: invalid student/employee ID
1.424 albertel 5575:
5576: If the CODE option is used that determines the randomization of the
1.556 weissno 5577: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5578: username:domain.
5579:
5580: During the validation phase the instructor can choose to skip scanlines.
5581:
1.659 raeburn 5582: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5583:
5584: scantron_original_filename (unmodified original file)
5585: scantron_corrected_filename (file where the corrected information has replaced the original information)
5586: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5587:
5588: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5589: correction information that isn't representable in the bubblesheet
1.424 albertel 5590: file (see &scantron_getfile() for more information)
5591:
5592: After all scanlines are either valid, marked as valid or skipped, then
5593: foreach line foreach problem in the picked sequence, an ssi request is
5594: made that simulates a user submitting their selected letter(s) against
5595: the homework problem.

10876: =head1 NAME
10877:
10878: Apache::grades
10879:
10880: =head1 SYNOPSIS
10881:
10882: Handles the viewing of grades.
10883:
10884: This is part of the LearningOnline Network with CAPA project
10885: described at http://www.lon-capa.org.
10886:
10887: =head1 OVERVIEW
10888:
10889: Do an ssi with retries:
1.715 bisitz 10890: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10891: 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
10892: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10893:
10894: At least the logic that drives this has been pulled out into loncommon.
10895:
10896:
10897:
10898: ssi_with_retries - Does the server side include of a resource.
10899: if the ssi call returns an error we'll retry it up to
10900: the number of times requested by the caller.
1.715 bisitz 10901: If we still have a problem, no text is appended to the
1.531 jms 10902: output and we set some global variables.
10903: to indicate to the caller an SSI error occurred.
10904: All of this is supposed to deal with the issues described
1.715 bisitz 10905: in LON-CAPA BZ 5631 see:
1.531 jms 10906: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10907: by informing the user that this happened.
10908:
10909: Parameters:
10910: resource - The resource to include. This is passed directly, without
10911: interpretation to lonnet::ssi.
10912: form - The form hash parameters that guide the interpretation of the resource
10913:
10914: retries - Number of retries allowed before giving up completely.
10915: Returns:
10916: On success, returns the rendered resource identified by the resource parameter.
10917: Side Effects:
10918: The following global variables can be set:
10919: ssi_error - If an unrecoverable error occurred this becomes true.
10920: It is up to the caller to initialize this to false
10921: if desired.
10922: ssi_error_resource - If an unrecoverable error occurred, this is the value
10923: of the resource that could not be rendered by the ssi
10924: call.
10925: ssi_error_message - The error string fetched from the ssi response
10926: in the event of an error.

10936:
1.671 raeburn 10937: =head1 Routines to display previous version of a Task for a specific student
10938:
10939: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10940: can receive another opportunity. Access to tasks is slot-based. If a slot
10941: requires a proctor to check-in the student, a new version of the Task will
10942: be created when the student is checked in to the new opportunity.
10943:
10944: If a particular student has tried two or more versions of a particular task,
10945: the submission screen provides a user with vgr privileges (e.g., a Course
10946: Coordinator) the ability to display a previous version worked on by the
10947: student. By default, the current version is displayed. If a previous version
10948: has been selected for display, submission data are only shown that pertain
10949: to that particular version, and the interface to submit grades is not shown.

10960:

10962:
10963: Side Effects: calls &show_problem() to print version of Task, with

10965:
10966: =item choose_task_version_form()
10967:
10968: Displays a web form used to select which version of a student's view of a

10970: content in existing pop-up, or replaces page in main window.
10971:
10972: Inputs: 4
10973: symb - unique symb for current instance of resource

10977: breadcrumbs etc., are displayed
10978:
10979: Output: 4
10980: current - student's current version
10981: displayed - student's version being displayed
10982: result - scalar containing HTML for web form used to switch to
10983: a different version (or a link to close window, if pop-up).
10984: js - javascript for processing selection in versions web form
10985:

10993: current - student's current version number.
