7037:
1.424 albertel 7038: For this documentation:
7039:
7040: 'scanline' refers to the full line of characters
7041: from the file that we are parsing that represents one entire sheet
7042:
7043: 'bubble line' refers to the data
1.659 raeburn 7044: representing the line of bubbles that are on the physical bubblesheet
1.424 albertel 7045:
7046:
1.659 raeburn 7047: The overall process is that a scanned in bubblesheet data is uploaded
1.424 albertel 7048: into a course. When a user wants to grade, they select a
1.659 raeburn 7049: sequence/folder of resources, a file of bubblesheet info, and pick
1.424 albertel 7050: one of the predefined configurations for what each scanline looks
7051: like.
7052:
7053: Next each scanline is checked for any errors of either 'missing
1.435 foxr 7054: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 7055: because too light bubbling), 'double bubble' (each bubble line should
1.703 bisitz 7056: have no more than one letter picked), invalid or duplicated CODE,
1.556 weissno 7057: invalid student/employee ID
1.424 albertel 7058:
7059: If the CODE option is used that determines the randomization of the
1.556 weissno 7060: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 7061: username:domain.
7062:
7063: During the validation phase the instructor can choose to skip scanlines.
7064:
1.659 raeburn 7065: After the validation phase, there are now 3 bubblesheet files
1.424 albertel 7066:
7067: scantron_original_filename (unmodified original file)
7068: scantron_corrected_filename (file where the corrected information has replaced the original information)
7069: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
7070:
7071: Also there is a separate hash nohist_scantrondata that contains extra
1.659 raeburn 7072: correction information that isn't representable in the bubblesheet
1.424 albertel 7073: file (see &scantron_getfile() for more information)
7074:
7075: After all scanlines are either valid, marked as valid or skipped, then
7076: foreach line foreach problem in the picked sequence, an ssi request is
7077: made that simulates a user submitting their selected letter(s) against
7078: the homework problem.

13087:
13088: =head1 SYNOPSIS
13089:
13090: Handles the viewing of grades.
13091:
13092: This is part of the LearningOnline Network with CAPA project
13093: described at http://www.lon-capa.org.
13094:
13095: =head1 OVERVIEW
13096:
13097: Do an ssi with retries:
1.715 bisitz 13098: While I'd love to factor out this with the version in lonprintout,
1.531 jms 13099: 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
13100: I'm not quite ready to invent (e.g. an ssi_with_retry object).
13101:
13102: At least the logic that drives this has been pulled out into loncommon.
13103:
13104:
13105:
13106: ssi_with_retries - Does the server side include of a resource.
13107: if the ssi call returns an error we'll retry it up to
13108: the number of times requested by the caller.
1.715 bisitz 13109: If we still have a problem, no text is appended to the
1.531 jms 13110: output and we set some global variables.
13111: to indicate to the caller an SSI error occurred.
13112: All of this is supposed to deal with the issues described
1.715 bisitz 13113: in LON-CAPA BZ 5631 see:
1.531 jms 13114: http://bugs.lon-capa.org/show_bug.cgi?id=5631
13115: by informing the user that this happened.
13116:
13117: Parameters:
13118: resource - The resource to include. This is passed directly, without
13119: interpretation to lonnet::ssi.
13120: form - The form hash parameters that guide the interpretation of the resource
13121:
13122: retries - Number of retries allowed before giving up completely.
13123: Returns:
13124: On success, returns the rendered resource identified by the resource parameter.
13125: Side Effects:
13126: The following global variables can be set:
13127: ssi_error - If an unrecoverable error occurred this becomes true.
13128: It is up to the caller to initialize this to false
13129: if desired.
13130: ssi_error_resource - If an unrecoverable error occurred, this is the value
13131: of the resource that could not be rendered by the ssi
13132: call.
13133: ssi_error_message - The error string fetched from the ssi response
13134: in the event of an error.

1.671 raeburn 13145: =head1 Routines to display previous version of a Task for a specific student
13146:
13147: Tasks are graded pass/fail. Students who have yet to pass a particular Task
13148: can receive another opportunity. Access to tasks is slot-based. If a slot
13149: requires a proctor to check-in the student, a new version of the Task will
13150: be created when the student is checked in to the new opportunity.
13151:
13152: If a particular student has tried two or more versions of a particular task,
13153: the submission screen provides a user with vgr privileges (e.g., a Course
13154: Coordinator) the ability to display a previous version worked on by the
13155: student. By default, the current version is displayed. If a previous version
13156: has been selected for display, submission data are only shown that pertain
13157: to that particular version, and the interface to submit grades is not shown.

13160:
13161: =item show_previous_task_version()
13162:

13164:

13168:

13170:
13171: Side Effects: calls &show_problem() to print version of Task, with

13173:
13174: =item choose_task_version_form()
13175:
13176: Displays a web form used to select which version of a student's view of a
13177: Task should be displayed. Either launches a pop-up window, or replaces
13178: content in existing pop-up, or replaces page in main window.
13179:
13180: Inputs: 4
13181: symb - unique symb for current instance of resource
13182: uname - username of student
13183: udom - domain of student
13184: nomenu - 1 if display is in a pop-up window, and hence no menu
13185: breadcrumbs etc., are displayed
13186:
13187: Output: 4
13188: current - student's current version
13189: displayed - student's version being displayed
