1.424 albertel 5110: For this documentation:
5111:
5112: 'scanline' refers to the full line of characters
5113: from the file that we are parsing that represents one entire sheet
5114:
5115: 'bubble line' refers to the data
1.659 raeburn 5116: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 5117:
5118:
1.659 raeburn 5119: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 5120: into a course. When a user wants to grade, they select a
1.659 raeburn 5121: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 5122: one of the predefined configurations for what each scanline looks
5123: like.
5124:
5125: Next each scanline is checked for any errors of either 'missing
1.435 foxr 5126: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 5127: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 5128: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 5129: invalid student/employee ID
1.424 albertel 5130:
5131: If the CODE option is used that determines the randomization of the
1.556 weissno 5132: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 5133: username:domain.
5134:
5135: During the validation phase the instructor can choose to skip scanlines.
5136:
1.659 raeburn 5137: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 5138:
5139: scantron_original_filename (unmodified original file)
5140: scantron_corrected_filename (file where the corrected information has replaced the original information)
5141: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5142:
5143: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 5144: correction information that isn't representable in the bubblesheet
1.424 albertel 5145: file (see &scantron_getfile() for more information)
5146:
5147: After all scanlines are either valid, marked as valid or skipped, then
5148: foreach line foreach problem in the picked sequence, an ssi request is
5149: made that simulates a user submitting their selected letter(s) against
5150: the homework problem.

10380:
10381: Apache::grades
10382:
10383: =head1 SYNOPSIS
10384:
10385: Handles the viewing of grades.
10386:
10387: This is part of the LearningOnline Network with CAPA project
10388: described at http://www.lon-capa.org.
10389:
10390: =head1 OVERVIEW
10391:
10392: Do an ssi with retries:
1.715 bisitz 10393: While I'd love to factor out this with the version in lonprintout,
1.531 jms 10394: 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
10395: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10396:
10397: At least the logic that drives this has been pulled out into loncommon.
10398:
10399:
10400:
10401: ssi_with_retries - Does the server side include of a resource.
10402: if the ssi call returns an error we'll retry it up to
10403: the number of times requested by the caller.
1.715 bisitz 10404: If we still have a problem, no text is appended to the
1.531 jms 10405: output and we set some global variables.
10406: to indicate to the caller an SSI error occurred.
10407: All of this is supposed to deal with the issues described
1.715 bisitz 10408: in LON-CAPA BZ 5631 see:
1.531 jms 10409: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10410: by informing the user that this happened.
10411:
10412: Parameters:
10413: resource - The resource to include. This is passed directly, without
10414: interpretation to lonnet::ssi.
10415: form - The form hash parameters that guide the interpretation of the resource
10416:
10417: retries - Number of retries allowed before giving up completely.
10418: Returns:
10419: On success, returns the rendered resource identified by the resource parameter.
10420: Side Effects:
10421: The following global variables can be set:
10422: ssi_error - If an unrecoverable error occurred this becomes true.
10423: It is up to the caller to initialize this to false
10424: if desired.
10425: ssi_error_resource - If an unrecoverable error occurred, this is the value
10426: of the resource that could not be rendered by the ssi
10427: call.
10428: ssi_error_message - The error string fetched from the ssi response
10429: in the event of an error.

10439:
1.671 raeburn 10440: =head1 Routines to display previous version of a Task for a specific student
10441:
10442: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10443: can receive another opportunity. Access to tasks is slot-based. If a slot
10444: requires a proctor to check-in the student, a new version of the Task will
10445: be created when the student is checked in to the new opportunity.
10446:
10447: If a particular student has tried two or more versions of a particular task,
10448: the submission screen provides a user with vgr privileges (e.g., a Course
10449: Coordinator) the ability to display a previous version worked on by the
10450: student. By default, the current version is displayed. If a previous version
10451: has been selected for display, submission data are only shown that pertain
10452: to that particular version, and the interface to submit grades is not shown.
10453:
10454: =over 4
10455:
10456: =item show_previous_task_version()
10457:
10458: Displays a specified version of a student's Task, as the student sees it.
10459:
10460: Inputs: 2
10461: request - request object
10462: symb - unique symb for current instance of resource
10463:
10464: Output: None.
10465:
10466: Side Effects: calls &show_problem() to print version of Task, with
10467: version contained in form item: $env{'form.previousversion'}
10468:
10469: =item choose_task_version_form()
10470:
10471: Displays a web form used to select which version of a student's view of a
10472: Task should be displayed. Either launches a pop-up window, or replaces
10473: content in existing pop-up, or replaces page in main window.
