5599: =head1 Bubble sheet grading routines
5600:
5601: For this documentation:
5602:
5603: 'scanline' refers to the full line of characters
5604: from the file that we are parsing that represents one entire sheet
5605:
5606: 'bubble line' refers to the data
5607: representing the line of bubbles that are on the physical bubblesheet
5608:
5609:
5610: The overall process is that a scanned in bubblesheet data is uploaded
5611: into a course. When a user wants to grade, they select a
5612: sequence/folder of resources, a file of bubblesheet info, and pick
5613: one of the predefined configurations for what each scanline looks
5614: like.
5615:
5616: Next each scanline is checked for any errors of either 'missing
5617: bubbles' (it's an error because it may have been mis-scanned
5618: because too light bubbling), 'double bubble' (each bubble line should
5619: have no more than one letter picked), invalid or duplicated CODE,
5620: invalid student/employee ID
5621:
5622: If the CODE option is used that determines the randomization of the
5623: homework problems, either way the student/employee ID is looked up into a
5624: username:domain.
5625:
5626: During the validation phase the instructor can choose to skip scanlines.
5627:
5628: After the validation phase, there are now 3 bubblesheet files
5629:
5630: scantron_original_filename (unmodified original file)
5631: scantron_corrected_filename (file where the corrected information has replaced the original information)
5632: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5633:
5634: Also there is a separate hash nohist_scantrondata that contains extra
5635: correction information that isn't representable in the bubblesheet
5636: file (see &scantron_getfile() for more information)
5637:
5638: After all scanlines are either valid, marked as valid or skipped, then
5639: foreach line foreach problem in the picked sequence, an ssi request is
5640: made that simulates a user submitting their selected letter(s) against
5641: the homework problem.

10953: =head1 NAME
10954:
10955: Apache::grades
10956:
10957: =head1 SYNOPSIS
10958:
10959: Handles the viewing of grades.
10960:
10961: This is part of the LearningOnline Network with CAPA project
10962: described at http://www.lon-capa.org.
10963:
10964: =head1 OVERVIEW
10965:
10966: Do an ssi with retries:
10967: While I'd love to factor out this with the version in lonprintout,
10968: 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
10969: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10970:
10971: At least the logic that drives this has been pulled out into loncommon.
10972:
10973:
10974:
10975: ssi_with_retries - Does the server side include of a resource.
10976: if the ssi call returns an error we'll retry it up to
10977: the number of times requested by the caller.
10978: If we still have a problem, no text is appended to the
10979: output and we set some global variables.
10980: to indicate to the caller an SSI error occurred.
10981: All of this is supposed to deal with the issues described
10982: in LON-CAPA BZ 5631 see:
10983: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10984: by informing the user that this happened.
10985:
10986: Parameters:
10987: resource - The resource to include. This is passed directly, without
10988: interpretation to lonnet::ssi.
10989: form - The form hash parameters that guide the interpretation of the resource
10990:
10991: retries - Number of retries allowed before giving up completely.
10992: Returns:
10993: On success, returns the rendered resource identified by the resource parameter.
10994: Side Effects:
10995: The following global variables can be set:
10996: ssi_error - If an unrecoverable error occurred this becomes true.
10997: It is up to the caller to initialize this to false
10998: if desired.
10999: ssi_error_resource - If an unrecoverable error occurred, this is the value
11000: of the resource that could not be rendered by the ssi
11001: call.
11002: ssi_error_message - The error string fetched from the ssi response
11003: in the event of an error.

11013:
11014: =head1 Routines to display previous version of a Task for a specific student
11015:
11016: Tasks are graded pass/fail. Students who have yet to pass a particular Task
11017: can receive another opportunity. Access to tasks is slot-based. If a slot
11018: requires a proctor to check-in the student, a new version of the Task will
11019: be created when the student is checked in to the new opportunity.
11020:
11021: If a particular student has tried two or more versions of a particular task,
11022: the submission screen provides a user with vgr privileges (e.g., a Course
11023: Coordinator) the ability to display a previous version worked on by the
11024: student. By default, the current version is displayed. If a previous version
11025: has been selected for display, submission data are only shown that pertain
11026: to that particular version, and the interface to submit grades is not shown.
11027:
11028: =over 4
11029:
11030: =item show_previous_task_version()
11031:

11036: symb - unique symb for current instance of resource
11037:
11038: Output: None.
11039:
11040: Side Effects: calls &show_problem() to print version of Task, with
11041: version contained in form item: $env{'form.previousversion'}
11042:
11043: =item choose_task_version_form()
11044:
11045: Displays a web form used to select which version of a student's view of a
11046: Task should be displayed. Either launches a pop-up window, or replaces
11047: content in existing pop-up, or replaces page in main window.
11048:
11049: Inputs: 4
11050: symb - unique symb for current instance of resource
11051: uname - username of student
11052: udom - domain of student
11053: nomenu - 1 if display is in a pop-up window, and hence no menu
11054: breadcrumbs etc., are displayed
11055:
11056: Output: 4
11057: current - student's current version
11058: displayed - student's version being displayed
11059: result - scalar containing HTML for web form used to switch to
11060: a different version (or a link to close window, if pop-up).
11061: js - javascript for processing selection in versions web form
11062:
11063: Side Effects: None.
11064:
11065: =item previous_display_javascript()
11066:
11067: Inputs: 2
11068: nomenu - 1 if display is in a pop-up window, and hence no menu
11069: breadcrumbs etc., are displayed.
11070: current - student's current version number.
11071:
11072: Output: 1
11073: js - javascript for processing selection in versions web form.
