5596: =head1 Bubble sheet grading routines
5597:
5598: For this documentation:
5599:
5600: 'scanline' refers to the full line of characters
5601: from the file that we are parsing that represents one entire sheet
5602:
5603: 'bubble line' refers to the data
5604: representing the line of bubbles that are on the physical bubblesheet
5605:
5606:
5607: The overall process is that a scanned in bubblesheet data is uploaded
5608: into a course. When a user wants to grade, they select a
5609: sequence/folder of resources, a file of bubblesheet info, and pick
5610: one of the predefined configurations for what each scanline looks
5611: like.
5612:
5613: Next each scanline is checked for any errors of either 'missing
5614: bubbles' (it's an error because it may have been mis-scanned
5615: because too light bubbling), 'double bubble' (each bubble line should
5616: have no more than one letter picked), invalid or duplicated CODE,
5617: invalid student/employee ID
5618:
5619: If the CODE option is used that determines the randomization of the
5620: homework problems, either way the student/employee ID is looked up into a
5621: username:domain.
5622:
5623: During the validation phase the instructor can choose to skip scanlines.
5624:
5625: After the validation phase, there are now 3 bubblesheet files
5626:
5627: scantron_original_filename (unmodified original file)
5628: scantron_corrected_filename (file where the corrected information has replaced the original information)
5629: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5630:
5631: Also there is a separate hash nohist_scantrondata that contains extra
5632: correction information that isn't representable in the bubblesheet
5633: file (see &scantron_getfile() for more information)
5634:
5635: After all scanlines are either valid, marked as valid or skipped, then
5636: foreach line foreach problem in the picked sequence, an ssi request is
5637: made that simulates a user submitting their selected letter(s) against
5638: the homework problem.

10880: =head1 NAME
10881:
10882: Apache::grades
10883:
10884: =head1 SYNOPSIS
10885:
10886: Handles the viewing of grades.
10887:
10888: This is part of the LearningOnline Network with CAPA project
10889: described at http://www.lon-capa.org.
10890:
10891: =head1 OVERVIEW
10892:
10893: Do an ssi with retries:
10894: While I'd love to factor out this with the version in lonprintout,
10895: 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
10896: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10897:
10898: At least the logic that drives this has been pulled out into loncommon.
10899:
10900:
10901:
10902: ssi_with_retries - Does the server side include of a resource.
10903: if the ssi call returns an error we'll retry it up to
10904: the number of times requested by the caller.
10905: If we still have a problem, no text is appended to the
10906: output and we set some global variables.
10907: to indicate to the caller an SSI error occurred.
10908: All of this is supposed to deal with the issues described
10909: in LON-CAPA BZ 5631 see:
10910: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10911: by informing the user that this happened.
10912:
10913: Parameters:
10914: resource - The resource to include. This is passed directly, without
10915: interpretation to lonnet::ssi.
10916: form - The form hash parameters that guide the interpretation of the resource
10917:
10918: retries - Number of retries allowed before giving up completely.
10919: Returns:
10920: On success, returns the rendered resource identified by the resource parameter.
10921: Side Effects:
10922: The following global variables can be set:
10923: ssi_error - If an unrecoverable error occurred this becomes true.
10924: It is up to the caller to initialize this to false
10925: if desired.
10926: ssi_error_resource - If an unrecoverable error occurred, this is the value
10927: of the resource that could not be rendered by the ssi
10928: call.
10929: ssi_error_message - The error string fetched from the ssi response
10930: in the event of an error.

10940:
10941: =head1 Routines to display previous version of a Task for a specific student
10942:
10943: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10944: can receive another opportunity. Access to tasks is slot-based. If a slot
10945: requires a proctor to check-in the student, a new version of the Task will
10946: be created when the student is checked in to the new opportunity.
10947:
10948: If a particular student has tried two or more versions of a particular task,
10949: the submission screen provides a user with vgr privileges (e.g., a Course
10950: Coordinator) the ability to display a previous version worked on by the
10951: student. By default, the current version is displayed. If a previous version
10952: has been selected for display, submission data are only shown that pertain
10953: to that particular version, and the interface to submit grades is not shown.
10954:
10955: =over 4
10956:
10957: =item show_previous_task_version()
10958:
10959: Displays a specified version of a student's Task, as the student sees it.

10963: symb - unique symb for current instance of resource
10964:
10965: Output: None.
10966:
10967: Side Effects: calls &show_problem() to print version of Task, with
10968: version contained in form item: $env{'form.previousversion'}
10969:
10970: =item choose_task_version_form()
10971:
10972: Displays a web form used to select which version of a student's view of a
10973: Task should be displayed. Either launches a pop-up window, or replaces
10974: content in existing pop-up, or replaces page in main window.
10975:
10976: Inputs: 4
10977: symb - unique symb for current instance of resource
10978: uname - username of student
10979: udom - domain of student
10980: nomenu - 1 if display is in a pop-up window, and hence no menu
10981: breadcrumbs etc., are displayed
10982:
10983: Output: 4
10984: current - student's current version
10985: displayed - student's version being displayed
10986: result - scalar containing HTML for web form used to switch to
10987: a different version (or a link to close window, if pop-up).
10988: js - javascript for processing selection in versions web form
10989:
10990: Side Effects: None.
10991:
10992: =item previous_display_javascript()
10993:
10994: Inputs: 2
10995: nomenu - 1 if display is in a pop-up window, and hence no menu
10996: breadcrumbs etc., are displayed.
10997: current - student's current version number.
10998:
10999: Output: 1
11000: js - javascript for processing selection in versions web form.

11051: failure to retrieve a navmap object.
11052: if $nav_error is set to 1 by scantron_get_maxbubble(), the

11056: $scantron_config - Reference to bubblesheet format configuration hash.
11057:
11058: Returns the maximum number of bubble lines that are expected to

11080:
11081: Routine that does the actual grading of the bubblesheet information.
11082:
11083: The parsed scanline hash is added to %env

11085: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
