5755: =head1 Bubble sheet grading routines
5756:
5757: For this documentation:
5758:
5759: 'scanline' refers to the full line of characters
5760: from the file that we are parsing that represents one entire sheet
5761:
5762: 'bubble line' refers to the data
5763: representing the line of bubbles that are on the physical bubblesheet
5764:
5765:
5766: The overall process is that a scanned in bubblesheet data is uploaded
5767: into a course. When a user wants to grade, they select a
5768: sequence/folder of resources, a file of bubblesheet info, and pick
5769: one of the predefined configurations for what each scanline looks
5770: like.
5771:
5772: Next each scanline is checked for any errors of either 'missing
5773: bubbles' (it's an error because it may have been mis-scanned
5774: because too light bubbling), 'double bubble' (each bubble line should
5775: have no more than one letter picked), invalid or duplicated CODE,
5776: invalid student/employee ID
5777:
5778: If the CODE option is used that determines the randomization of the
5779: homework problems, either way the student/employee ID is looked up into a
5780: username:domain.
5781:
5782: During the validation phase the instructor can choose to skip scanlines.
5783:
5784: After the validation phase, there are now 3 bubblesheet files
5785:
5786: scantron_original_filename (unmodified original file)
5787: scantron_corrected_filename (file where the corrected information has replaced the original information)
5788: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5789:
5790: Also there is a separate hash nohist_scantrondata that contains extra
5791: correction information that isn't representable in the bubblesheet
5792: file (see &scantron_getfile() for more information)
5793:
5794: After all scanlines are either valid, marked as valid or skipped, then
5795: foreach line foreach problem in the picked sequence, an ssi request is
5796: made that simulates a user submitting their selected letter(s) against
5797: the homework problem.

11571: =head1 NAME
11572:
11573: Apache::grades
11574:
11575: =head1 SYNOPSIS
11576:
11577: Handles the viewing of grades.
11578:
11579: This is part of the LearningOnline Network with CAPA project
11580: described at http://www.lon-capa.org.
11581:
11582: =head1 OVERVIEW
11583:
11584: Do an ssi with retries:
11585: While I'd love to factor out this with the version in lonprintout,
11586: 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
11587: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11588:
11589: At least the logic that drives this has been pulled out into loncommon.
11590:
11591:
11592:
11593: ssi_with_retries - Does the server side include of a resource.
11594: if the ssi call returns an error we'll retry it up to
11595: the number of times requested by the caller.
11596: If we still have a problem, no text is appended to the
11597: output and we set some global variables.
11598: to indicate to the caller an SSI error occurred.
11599: All of this is supposed to deal with the issues described
11600: in LON-CAPA BZ 5631 see:
11601: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11602: by informing the user that this happened.
11603:
11604: Parameters:
11605: resource - The resource to include. This is passed directly, without
11606: interpretation to lonnet::ssi.
11607: form - The form hash parameters that guide the interpretation of the resource
11608:
11609: retries - Number of retries allowed before giving up completely.
11610: Returns:
11611: On success, returns the rendered resource identified by the resource parameter.
11612: Side Effects:
11613: The following global variables can be set:
11614: ssi_error - If an unrecoverable error occurred this becomes true.
11615: It is up to the caller to initialize this to false
11616: if desired.
11617: ssi_error_resource - If an unrecoverable error occurred, this is the value
11618: of the resource that could not be rendered by the ssi
11619: call.
11620: ssi_error_message - The error string fetched from the ssi response
11621: in the event of an error.
11622:

11624: =head1 HANDLER SUBROUTINE
11625:

11628: =head1 SUBROUTINES
11629:
11630: =over
11631:
11632: =head1 Routines to display previous version of a Task for a specific student
11633:
11634: Tasks are graded pass/fail. Students who have yet to pass a particular Task
11635: can receive another opportunity. Access to tasks is slot-based. If a slot
11636: requires a proctor to check-in the student, a new version of the Task will
11637: be created when the student is checked in to the new opportunity.
11638:
11639: If a particular student has tried two or more versions of a particular task,
11640: the submission screen provides a user with vgr privileges (e.g., a Course
11641: Coordinator) the ability to display a previous version worked on by the
11642: student. By default, the current version is displayed. If a previous version
11643: has been selected for display, submission data are only shown that pertain
11644: to that particular version, and the interface to submit grades is not shown.
11645:
11646: =over 4
11647:
11648: =item show_previous_task_version()
11649:
11650: Displays a specified version of a student's Task, as the student sees it.
11651:
11652: Inputs: 2
11653: request - request object
11654: symb - unique symb for current instance of resource
11655:
11656: Output: None.
11657:
11658: Side Effects: calls &show_problem() to print version of Task, with
11659: version contained in form item: $env{'form.previousversion'}
11660:
11661: =item choose_task_version_form()
11662:
11663: Displays a web form used to select which version of a student's view of a
11664: Task should be displayed. Either launches a pop-up window, or replaces
11665: content in existing pop-up, or replaces page in main window.
11666:
11667: Inputs: 4
11668: symb - unique symb for current instance of resource
11669: uname - username of student
11670: udom - domain of student
11671: nomenu - 1 if display is in a pop-up window, and hence no menu
11672: breadcrumbs etc., are displayed
11673:
11674: Output: 4
11675: current - student's current version
11676: displayed - student's version being displayed
11677: result - scalar containing HTML for web form used to switch to
11678: a different version (or a link to close window, if pop-up).

11707: $r - Apache request object
11708: $i - number of the current scanline
11709: $scan_record - hash ref as returned from &scantron_parse_scanline()

11719: - duplicateCODE - array ref of the paper numbers this CODE was
11720: seen on before
11721: - incorrectCODE - current incorrect CODE

11731: in "Master Seqence" (as seen by Course Coordinator).
11732: $startline - Reference to hash where key is question number (0 is first)

11740: Arguments:
11741: $nav_error - Reference to scalar which is a flag to indicate a
11742: failure to retrieve a navmap object.
11743: if $nav_error is set to 1 by scantron_get_maxbubble(), the
11744: calling routine should trap the error condition and display the warning
11745: found in &navmap_errormsg().

11747: $scantron_config - Reference to bubblesheet format configuration hash.
11748:
11749: Returns the maximum number of bubble lines that are expected to
11750: occur. Does this by walking the selected sequence rendering the
11751: resource and then checking &Apache::lonxml::get_problem_counter()
11752: for what the current value of the problem counter is.

11757: $env{"form.scantron.sub_bubblelines.n"}
11758: which are the total number of bubble lines, the number of bubble
11759: lines for response n and number of the first bubble line for response n,

11771:
11772: Routine that does the actual grading of the bubblesheet information.
11773:
11774: The parsed scanline hash is added to %env
11775:
11776: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()

11783: 'grade_courseid'=> of course
11784: 'grade_symb' => symb of resource to grade
11785:
11786: This triggers a grading pass. The problem grading code takes care
11787: of converting the bubbled letter information (now in %env) into a
11788: valid submission.
