5329: =head1 Bubble sheet grading routines
5330:
5331: For this documentation:
5332:
5333: 'scanline' refers to the full line of characters
5334: from the file that we are parsing that represents one entire sheet
5335:
5336: 'bubble line' refers to the data
5337: representing the line of bubbles that are on the physical bubblesheet
5338:
5339:
5340: The overall process is that a scanned in bubblesheet data is uploaded
5341: into a course. When a user wants to grade, they select a
5342: sequence/folder of resources, a file of bubblesheet info, and pick
5343: one of the predefined configurations for what each scanline looks
5344: like.
5345:
5346: Next each scanline is checked for any errors of either 'missing
5347: bubbles' (it's an error because it may have been mis-scanned
5348: because too light bubbling), 'double bubble' (each bubble line should
5349: have no more than one letter picked), invalid or duplicated CODE,
5350: invalid student/employee ID
5351:
5352: If the CODE option is used that determines the randomization of the
5353: homework problems, either way the student/employee ID is looked up into a
5354: username:domain.
5355:
5356: During the validation phase the instructor can choose to skip scanlines.
5357:
5358: After the validation phase, there are now 3 bubblesheet files

10630: =head1 NAME
10631:
10632: Apache::grades
10633:
10634: =head1 SYNOPSIS
10635:
10636: Handles the viewing of grades.
10637:
10638: This is part of the LearningOnline Network with CAPA project
10639: described at http://www.lon-capa.org.
10640:
10641: =head1 OVERVIEW
10642:
10643: Do an ssi with retries:
10644: While I'd love to factor out this with the version in lonprintout,
10645: 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
10646: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10647:
10648: At least the logic that drives this has been pulled out into loncommon.
10649:
10650:
10651:
10652: ssi_with_retries - Does the server side include of a resource.
10653: if the ssi call returns an error we'll retry it up to
10654: the number of times requested by the caller.
10655: If we still have a problem, no text is appended to the
10656: output and we set some global variables.
10657: to indicate to the caller an SSI error occurred.
10658: All of this is supposed to deal with the issues described
10659: in LON-CAPA BZ 5631 see:
10660: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10661: by informing the user that this happened.
10662:
10663: Parameters:
10664: resource - The resource to include. This is passed directly, without
10665: interpretation to lonnet::ssi.
10666: form - The form hash parameters that guide the interpretation of the resource
10667:
10668: retries - Number of retries allowed before giving up completely.
10669: Returns:
10670: On success, returns the rendered resource identified by the resource parameter.
10671: Side Effects:
10672: The following global variables can be set:
10673: ssi_error - If an unrecoverable error occurred this becomes true.
10674: It is up to the caller to initialize this to false
10675: if desired.
10676: ssi_error_resource - If an unrecoverable error occurred, this is the value
10677: of the resource that could not be rendered by the ssi
10678: call.
10679: ssi_error_message - The error string fetched from the ssi response
10680: in the event of an error.

10690:
10691: =head1 Routines to display previous version of a Task for a specific student
10692:
10693: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10694: can receive another opportunity. Access to tasks is slot-based. If a slot
10695: requires a proctor to check-in the student, a new version of the Task will
10696: be created when the student is checked in to the new opportunity.
10697:
10698: If a particular student has tried two or more versions of a particular task,
10699: the submission screen provides a user with vgr privileges (e.g., a Course
10700: Coordinator) the ability to display a previous version worked on by the
10701: student. By default, the current version is displayed. If a previous version
10702: has been selected for display, submission data are only shown that pertain
10703: to that particular version, and the interface to submit grades is not shown.
10704:
10705: =over 4
10706:
10707: =item show_previous_task_version()

10713: symb - unique symb for current instance of resource
10714:
10715: Output: None.
10716:
10717: Side Effects: calls &show_problem() to print version of Task, with

10719:
10720: =item choose_task_version_form()
10721:
10722: Displays a web form used to select which version of a student's view of a
10723: Task should be displayed. Either launches a pop-up window, or replaces
10724: content in existing pop-up, or replaces page in main window.
10725:
10726: Inputs: 4
10727: symb - unique symb for current instance of resource
10728: uname - username of student

10731: breadcrumbs etc., are displayed
10732:
10733: Output: 4
10734: current - student's current version
10735: displayed - student's version being displayed
10736: result - scalar containing HTML for web form used to switch to
10737: a different version (or a link to close window, if pop-up).
10738: js - javascript for processing selection in versions web form
10739:
10740: Side Effects: None.
10741:
10742: =item previous_display_javascript()
10743:
10744: Inputs: 2
10745: nomenu - 1 if display is in a pop-up window, and hence no menu
10746: breadcrumbs etc., are displayed.
10747: current - student's current version number.
10748:
10749: Output: 1
10750: js - javascript for processing selection in versions web form.
