5320: =head1 Bubble sheet grading routines
5321:
5322: For this documentation:
5323:
5324: 'scanline' refers to the full line of characters
5325: from the file that we are parsing that represents one entire sheet
5326:
5327: 'bubble line' refers to the data
5328: representing the line of bubbles that are on the physical bubblesheet
5329:
5330:
5331: The overall process is that a scanned in bubblesheet data is uploaded
5332: into a course. When a user wants to grade, they select a
5333: sequence/folder of resources, a file of bubblesheet info, and pick
5334: one of the predefined configurations for what each scanline looks
5335: like.
5336:
5337: Next each scanline is checked for any errors of either 'missing
5338: bubbles' (it's an error because it may have been mis-scanned
5339: because too light bubbling), 'double bubble' (each bubble line should
5340: have no more than one letter picked), invalid or duplicated CODE,
5341: invalid student/employee ID
5342:
5343: If the CODE option is used that determines the randomization of the
5344: homework problems, either way the student/employee ID is looked up into a
5345: username:domain.
5346:
5347: During the validation phase the instructor can choose to skip scanlines.
5348:
5349: After the validation phase, there are now 3 bubblesheet files
5350:
5351: scantron_original_filename (unmodified original file)
5352: scantron_corrected_filename (file where the corrected information has replaced the original information)
5353: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5354:
5355: Also there is a separate hash nohist_scantrondata that contains extra
5356: correction information that isn't representable in the bubblesheet
5357: file (see &scantron_getfile() for more information)
5358:
5359: After all scanlines are either valid, marked as valid or skipped, then
5360: foreach line foreach problem in the picked sequence, an ssi request is
5361: made that simulates a user submitting their selected letter(s) against
5362: the homework problem.

10622:
10623: Apache::grades
10624:
10625: =head1 SYNOPSIS
10626:
10627: Handles the viewing of grades.
10628:
10629: This is part of the LearningOnline Network with CAPA project
10630: described at http://www.lon-capa.org.
10631:
10632: =head1 OVERVIEW
10633:
10634: Do an ssi with retries:
10635: While I'd love to factor out this with the version in lonprintout,
10636: 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
10637: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10638:
10639: At least the logic that drives this has been pulled out into loncommon.
10640:
10641:
10642:
10643: ssi_with_retries - Does the server side include of a resource.
10644: if the ssi call returns an error we'll retry it up to
10645: the number of times requested by the caller.
10646: If we still have a problem, no text is appended to the
10647: output and we set some global variables.
10648: to indicate to the caller an SSI error occurred.
10649: All of this is supposed to deal with the issues described
10650: in LON-CAPA BZ 5631 see:
10651: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10652: by informing the user that this happened.
10653:
10654: Parameters:
10655: resource - The resource to include. This is passed directly, without
10656: interpretation to lonnet::ssi.
10657: form - The form hash parameters that guide the interpretation of the resource
10658:
10659: retries - Number of retries allowed before giving up completely.
10660: Returns:
10661: On success, returns the rendered resource identified by the resource parameter.
10662: Side Effects:
10663: The following global variables can be set:
10664: ssi_error - If an unrecoverable error occurred this becomes true.
10665: It is up to the caller to initialize this to false
10666: if desired.
10667: ssi_error_resource - If an unrecoverable error occurred, this is the value
10668: of the resource that could not be rendered by the ssi
10669: call.
10670: ssi_error_message - The error string fetched from the ssi response
10671: in the event of an error.

10681:
10682: =head1 Routines to display previous version of a Task for a specific student
10683:
10684: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10685: can receive another opportunity. Access to tasks is slot-based. If a slot
10686: requires a proctor to check-in the student, a new version of the Task will
10687: be created when the student is checked in to the new opportunity.
10688:
10689: If a particular student has tried two or more versions of a particular task,
10690: the submission screen provides a user with vgr privileges (e.g., a Course
10691: Coordinator) the ability to display a previous version worked on by the
10692: student. By default, the current version is displayed. If a previous version
10693: has been selected for display, submission data are only shown that pertain
10694: to that particular version, and the interface to submit grades is not shown.

10707:

10710:
10711: =item choose_task_version_form()
10712:
10713: Displays a web form used to select which version of a student's view of a

10723:
10724: Output: 4
10725: current - student's current version
10726: displayed - student's version being displayed
10727: result - scalar containing HTML for web form used to switch to
10728: a different version (or a link to close window, if pop-up).
10729: js - javascript for processing selection in versions web form
10730:
10731: Side Effects: None.
10732:
10733: =item previous_display_javascript()
10734:
10735: Inputs: 2
10736: nomenu - 1 if display is in a pop-up window, and hence no menu

10738: current - student's current version number.
10739:
10740: Output: 1
