5598: =head1 Bubble sheet grading routines
5599:
5600: For this documentation:
5601:
5602: 'scanline' refers to the full line of characters
5603: from the file that we are parsing that represents one entire sheet
5604:
5605: 'bubble line' refers to the data
5606: representing the line of bubbles that are on the physical bubblesheet
5607:
5608:
5609: The overall process is that a scanned in bubblesheet data is uploaded
5610: into a course. When a user wants to grade, they select a
5611: sequence/folder of resources, a file of bubblesheet info, and pick
5612: one of the predefined configurations for what each scanline looks
5613: like.
5614:
5615: Next each scanline is checked for any errors of either 'missing
5616: bubbles' (it's an error because it may have been mis-scanned
5617: because too light bubbling), 'double bubble' (each bubble line should
5618: have no more than one letter picked), invalid or duplicated CODE,
5619: invalid student/employee ID
5620:
5621: If the CODE option is used that determines the randomization of the
5622: homework problems, either way the student/employee ID is looked up into a
5623: username:domain.
5624:
5625: During the validation phase the instructor can choose to skip scanlines.
5626:
5627: After the validation phase, there are now 3 bubblesheet files
5628:
5629: scantron_original_filename (unmodified original file)
5630: scantron_corrected_filename (file where the corrected information has replaced the original information)
5631: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5632:
5633: Also there is a separate hash nohist_scantrondata that contains extra
5634: correction information that isn't representable in the bubblesheet
5635: file (see &scantron_getfile() for more information)
5636:
5637: After all scanlines are either valid, marked as valid or skipped, then
5638: foreach line foreach problem in the picked sequence, an ssi request is
5639: made that simulates a user submitting their selected letter(s) against
5640: the homework problem.

11382: =head1 NAME
11383:
11384: Apache::grades
11385:
11386: =head1 SYNOPSIS
11387:
11388: Handles the viewing of grades.
11389:
11390: This is part of the LearningOnline Network with CAPA project
11391: described at http://www.lon-capa.org.
11392:
11393: =head1 OVERVIEW
11394:
11395: Do an ssi with retries:
11396: While I'd love to factor out this with the version in lonprintout,
11397: 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
11398: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11399:
11400: At least the logic that drives this has been pulled out into loncommon.
11401:
11402:
11403:
11404: ssi_with_retries - Does the server side include of a resource.
11405: if the ssi call returns an error we'll retry it up to
11406: the number of times requested by the caller.
11407: If we still have a problem, no text is appended to the
11408: output and we set some global variables.
11409: to indicate to the caller an SSI error occurred.
11410: All of this is supposed to deal with the issues described
11411: in LON-CAPA BZ 5631 see:
11412: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11413: by informing the user that this happened.
11414:
11415: Parameters:
11416: resource - The resource to include. This is passed directly, without
11417: interpretation to lonnet::ssi.
11418: form - The form hash parameters that guide the interpretation of the resource
11419:
11420: retries - Number of retries allowed before giving up completely.
11421: Returns:
11422: On success, returns the rendered resource identified by the resource parameter.
11423: Side Effects:
11424: The following global variables can be set:
11425: ssi_error - If an unrecoverable error occurred this becomes true.
11426: It is up to the caller to initialize this to false
11427: if desired.
11428: ssi_error_resource - If an unrecoverable error occurred, this is the value
11429: of the resource that could not be rendered by the ssi
11430: call.
11431: ssi_error_message - The error string fetched from the ssi response
11432: in the event of an error.

11442:
11443: =head1 Routines to display previous version of a Task for a specific student
11444:
11445: Tasks are graded pass/fail. Students who have yet to pass a particular Task
11446: can receive another opportunity. Access to tasks is slot-based. If a slot
11447: requires a proctor to check-in the student, a new version of the Task will
11448: be created when the student is checked in to the new opportunity.
11449:
11450: If a particular student has tried two or more versions of a particular task,
11451: the submission screen provides a user with vgr privileges (e.g., a Course
11452: Coordinator) the ability to display a previous version worked on by the
11453: student. By default, the current version is displayed. If a previous version
11454: has been selected for display, submission data are only shown that pertain
11455: to that particular version, and the interface to submit grades is not shown.
11456:
11457: =over 4
11458:
11459: =item show_previous_task_version()

11465: symb - unique symb for current instance of resource
11466:
11467: Output: None.
11468:
11469: Side Effects: calls &show_problem() to print version of Task, with
11470: version contained in form item: $env{'form.previousversion'}
11471:
11472: =item choose_task_version_form()
11473:
11474: Displays a web form used to select which version of a student's view of a

11476: content in existing pop-up, or replaces page in main window.
11477:
11478: Inputs: 4
11479: symb - unique symb for current instance of resource
11480: uname - username of student
11481: udom - domain of student

11483: breadcrumbs etc., are displayed
11484:
11485: Output: 4
11486: current - student's current version
11487: displayed - student's version being displayed
11488: result - scalar containing HTML for web form used to switch to
11489: a different version (or a link to close window, if pop-up).
11490: js - javascript for processing selection in versions web form
11491:
11492: Side Effects: None.
11493:
11494: =item previous_display_javascript()
11495:
11496: Inputs: 2
11497: nomenu - 1 if display is in a pop-up window, and hence no menu
11498: breadcrumbs etc., are displayed.
11499: current - student's current version number.
11500:
11501: Output: 1
11502: js - javascript for processing selection in versions web form.
