1.424 albertel 5157: For this documentation:
5158:
5159: 'scanline' refers to the full line of characters
5160: from the file that we are parsing that represents one entire sheet
5161:
5162: 'bubble line' refers to the data
1.659 raeburn 5163: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5164:
5165:
1.659 raeburn 5166: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5167: into a course. When a user wants to grade, they select a
1.659 raeburn 5168: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5169: one of the predefined configurations for what each scanline looks
5170: like.
5171:
5172: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5173: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5174: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5175: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5176: invalid student/employee ID
1.424 albertel 5177:
5178: If the CODE option is used that determines the randomization of the
1.556 weissno 5179: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5180: username:domain.
5181:
5182: During the validation phase the instructor can choose to skip scanlines.
5183:
1.659 raeburn 5184: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5185:
5186: scantron_original_filename (unmodified original file)
5187: scantron_corrected_filename (file where the corrected information has replaced the original information)
5188: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5189:
5190: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5191: correction information that isn't representable in the bubblesheet
1.424 albertel 5192: file (see &scantron_getfile() for more information)
5193:
5194: After all scanlines are either valid, marked as valid or skipped, then
5195: foreach line foreach problem in the picked sequence, an ssi request is
5196: made that simulates a user submitting their selected letter(s) against
5197: the homework problem.

10444: Apache::grades
10445:
10446: =head1 SYNOPSIS
10447:
10448: Handles the viewing of grades.
10449:
10450: This is part of the LearningOnline Network with CAPA project
10451: described at http://www.lon-capa.org.
10452:
10453: =head1 OVERVIEW
10454:
10455: Do an ssi with retries:
1.715 bisitz 10456: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10457: 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
10458: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10459:
10460: At least the logic that drives this has been pulled out into loncommon.
10461:
10462:
10463:
10464: ssi_with_retries - Does the server side include of a resource.
10465: if the ssi call returns an error we'll retry it up to
10466: the number of times requested by the caller.
1.715 bisitz 10467: If we still have a problem, no text is appended to the
1.531 jms 10468: output and we set some global variables.
10469: to indicate to the caller an SSI error occurred.
10470: All of this is supposed to deal with the issues described
1.715 bisitz 10471: in LON-CAPA BZ 5631 see:
1.531 jms 10472: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10473: by informing the user that this happened.
10474:
10475: Parameters:
10476: resource - The resource to include. This is passed directly, without
10477: interpretation to lonnet::ssi.
10478: form - The form hash parameters that guide the interpretation of the resource
10479:
10480: retries - Number of retries allowed before giving up completely.
10481: Returns:
10482: On success, returns the rendered resource identified by the resource parameter.
10483: Side Effects:
10484: The following global variables can be set:
10485: ssi_error - If an unrecoverable error occurred this becomes true.
10486: It is up to the caller to initialize this to false
10487: if desired.
10488: ssi_error_resource - If an unrecoverable error occurred, this is the value
10489: of the resource that could not be rendered by the ssi
10490: call.
10491: ssi_error_message - The error string fetched from the ssi response
10492: in the event of an error.

10502:
1.671 raeburn 10503: =head1 Routines to display previous version of a Task for a specific student
10504:
10505: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10506: can receive another opportunity. Access to tasks is slot-based. If a slot
10507: requires a proctor to check-in the student, a new version of the Task will
10508: be created when the student is checked in to the new opportunity.
10509:
10510: If a particular student has tried two or more versions of a particular task,
10511: the submission screen provides a user with vgr privileges (e.g., a Course
10512: Coordinator) the ability to display a previous version worked on by the
10513: student. By default, the current version is displayed. If a previous version
10514: has been selected for display, submission data are only shown that pertain
10515: to that particular version, and the interface to submit grades is not shown.

10528:
10529: Side Effects: calls &show_problem() to print version of Task, with

10531:
10532: =item choose_task_version_form()
10533:
10534: Displays a web form used to select which version of a student's view of a

10536: content in existing pop-up, or replaces page in main window.
10537:
10538: Inputs: 4
10539: symb - unique symb for current instance of resource

10543: breadcrumbs etc., are displayed
10544:
10545: Output: 4
10546: current - student's current version
10547: displayed - student's version being displayed
10548: result - scalar containing HTML for web form used to switch to
10549: a different version (or a link to close window, if pop-up).
10550: js - javascript for processing selection in versions web form
10551:

10559: current - student's current version number.
