1.424 albertel 5181: For this documentation:
5182:
5183: 'scanline' refers to the full line of characters
5184: from the file that we are parsing that represents one entire sheet
5185:
5186: 'bubble line' refers to the data
1.659 raeburn 5187: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5188:
5189:
1.659 raeburn 5190: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5191: into a course. When a user wants to grade, they select a
1.659 raeburn 5192: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5193: one of the predefined configurations for what each scanline looks
5194: like.
5195:
5196: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5197: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5198: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5199: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5200: invalid student/employee ID
1.424 albertel 5201:
5202: If the CODE option is used that determines the randomization of the
1.556 weissno 5203: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5204: username:domain.
5205:
5206: During the validation phase the instructor can choose to skip scanlines.
5207:
1.659 raeburn 5208: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5209:
5210: scantron_original_filename (unmodified original file)
5211: scantron_corrected_filename (file where the corrected information has replaced the original information)
5212: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5213:
5214: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5215: correction information that isn't representable in the bubblesheet
1.424 albertel 5216: file (see &scantron_getfile() for more information)
5217:
5218: After all scanlines are either valid, marked as valid or skipped, then
5219: foreach line foreach problem in the picked sequence, an ssi request is
5220: made that simulates a user submitting their selected letter(s) against
5221: the homework problem.

10453:
10454: =head1 SYNOPSIS
10455:
10456: Handles the viewing of grades.
10457:
10458: This is part of the LearningOnline Network with CAPA project
10459: described at http://www.lon-capa.org.
10460:
10461: =head1 OVERVIEW
10462:
10463: Do an ssi with retries:
1.715 bisitz 10464: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10465: 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
10466: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10467:
10468: At least the logic that drives this has been pulled out into loncommon.
10469:
10470:
10471:
10472: ssi_with_retries - Does the server side include of a resource.
10473: if the ssi call returns an error we'll retry it up to
10474: the number of times requested by the caller.
1.715 bisitz 10475: If we still have a problem, no text is appended to the
1.531 jms 10476: output and we set some global variables.
10477: to indicate to the caller an SSI error occurred.
10478: All of this is supposed to deal with the issues described
1.715 bisitz 10479: in LON-CAPA BZ 5631 see:
1.531 jms 10480: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10481: by informing the user that this happened.
10482:
10483: Parameters:
10484: resource - The resource to include. This is passed directly, without
10485: interpretation to lonnet::ssi.
10486: form - The form hash parameters that guide the interpretation of the resource
10487:
10488: retries - Number of retries allowed before giving up completely.
10489: Returns:
10490: On success, returns the rendered resource identified by the resource parameter.
10491: Side Effects:
10492: The following global variables can be set:
10493: ssi_error - If an unrecoverable error occurred this becomes true.
10494: It is up to the caller to initialize this to false
10495: if desired.
10496: ssi_error_resource - If an unrecoverable error occurred, this is the value
10497: of the resource that could not be rendered by the ssi
10498: call.
10499: ssi_error_message - The error string fetched from the ssi response
10500: in the event of an error.

10510:
1.671 raeburn 10511: =head1 Routines to display previous version of a Task for a specific student
10512:
10513: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10514: can receive another opportunity. Access to tasks is slot-based. If a slot
10515: requires a proctor to check-in the student, a new version of the Task will
10516: be created when the student is checked in to the new opportunity.
10517:
10518: If a particular student has tried two or more versions of a particular task,
10519: the submission screen provides a user with vgr privileges (e.g., a Course
10520: Coordinator) the ability to display a previous version worked on by the
10521: student. By default, the current version is displayed. If a previous version
10522: has been selected for display, submission data are only shown that pertain
10523: to that particular version, and the interface to submit grades is not shown.

10536:
10537: Side Effects: calls &show_problem() to print version of Task, with

10539:
10540: =item choose_task_version_form()
10541:
10542: Displays a web form used to select which version of a student's view of a

10544: content in existing pop-up, or replaces page in main window.
10545:
10546: Inputs: 4
10547: symb - unique symb for current instance of resource

10551: breadcrumbs etc., are displayed
10552:
10553: Output: 4
10554: current - student's current version
10555: displayed - student's version being displayed
10556: result - scalar containing HTML for web form used to switch to
10557: a different version (or a link to close window, if pop-up).
10558: js - javascript for processing selection in versions web form
