Improve bubblesheet grading upload process - Better overview, consistent layout:
- Standard design using confirm_success
- Additionally show absolute matching results
- Skip warning and additional info about low percentage of matches in case of 100% matching.
- Consistent punctuation, consistent wording
- Updated related translation file entries
- de.pm: translation corrections and improvements

5070: =head1 Bubble sheet grading routines
5071:
5072: For this documentation:
5073:
5074: 'scanline' refers to the full line of characters
5075: from the file that we are parsing that represents one entire sheet
5076:
5077: 'bubble line' refers to the data
5078: representing the line of bubbles that are on the physical bubblesheet
5079:
5080:
5081: The overall process is that a scanned in bubblesheet data is uploaded
5082: into a course. When a user wants to grade, they select a
5083: sequence/folder of resources, a file of bubblesheet info, and pick
5084: one of the predefined configurations for what each scanline looks
5085: like.
5086:
5087: Next each scanline is checked for any errors of either 'missing
5088: bubbles' (it's an error because it may have been mis-scanned
5089: because too light bubbling), 'double bubble' (each bubble line should
5090: have no more than one letter picked), invalid or duplicated CODE,
5091: invalid student/employee ID
5092:
5093: If the CODE option is used that determines the randomization of the
5094: homework problems, either way the student/employee ID is looked up into a
5095: username:domain.
5096:
5097: During the validation phase the instructor can choose to skip scanlines.
5098:
5099: After the validation phase, there are now 3 bubblesheet files
5100:
5101: scantron_original_filename (unmodified original file)
5102: scantron_corrected_filename (file where the corrected information has replaced the original information)
5103: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5104:
5105: Also there is a separate hash nohist_scantrondata that contains extra
5106: correction information that isn't representable in the bubblesheet
5107: file (see &scantron_getfile() for more information)
5108:
5109: After all scanlines are either valid, marked as valid or skipped, then
5110: foreach line foreach problem in the picked sequence, an ssi request is
5111: made that simulates a user submitting their selected letter(s) against
5112: the homework problem.

5889: orderedforcode - Ref to hash of arrays. keys are CODEs and values
5890: are refs to an array of resource objects, ordered
5891: according to order used for CODE, when randomorder
5892: and or randompick are in use.
5893: respnumlookup - Ref to hash mapping question numbers in bubble lines
5894: for current line to question number used for same question
5895: in "Master Sequence" (as seen by Course Coordinator).
5896: startline - Ref to hash where key is question number (0 is first)
5897: and value is number of first bubble line for current
5898: student or code-based randompick and/or randomorder.
5899: totalref - Ref of scalar used to score total number of bubble
5900: lines needed for responses in a scan line (used when
5901: randompick in use.
5902:
5903: Returns:
5904: Hash containing the result of parsing the scanline
5905:
5906: Keys are all proceeded by the string 'scantron.'
5907:
5908: CODE - the CODE in use for this scanline
5909: useCODE - 1 if the CODE is invalid but it usage has been forced
5910: by the operator
5911: CODE_ignore_dup - 1 if the CODE is a duplicated use when unique
5912: CODEs were selected, but the usage has been
5913: forced by the operator
5914: ID - student/employee ID
5915: PaperID - if used, the ID number printed on the sheet when the
5916: paper was scanned
5917: FirstName - first name from the sheet
5918: LastName - last name from the sheet
5919:
5920: if just_header was not true these key may also exist
5921:
5922: missingerror - a list of bubble ranges that are considered to be answers
5923: to a single question that don't have any bubbles filled in.
5924: Of the form questionnumber:firstbubblenumber:count.
5925: doubleerror - a list of bubble ranges that are considered to be answers
5926: to a single question that have more than one bubble filled in.
5927: Of the form questionnumber::firstbubblenumber:count
5928:
5929: In the above, count is the number of bubble responses in the
5930: input line needed to represent the possible answers to the question.
5931: e.g. a radioresponse with 15 choices in an answer sheet with 10 choices
5932: per line would have count = 2.
5933:
5934: maxquest - the number of the last bubble line that was parsed
5935:
5936: (<number> starts at 1)
5937: <number>.answer - zero or more letters representing the selected
5938: letters from the scanline for the bubble line
5939: <number>.
5940: if blank there was either no bubble or there where
5941: multiple bubbles, (consult the keys missingerror and
5942: doubleerror if this is an error condition)

10341: =head1 NAME
10342:
10343: Apache::grades
10344:
10345: =head1 SYNOPSIS
10346:
10347: Handles the viewing of grades.
10348:
10349: This is part of the LearningOnline Network with CAPA project
10350: described at http://www.lon-capa.org.
10351:
10352: =head1 OVERVIEW
10353:
10354: Do an ssi with retries:
10355: While I'd love to factor out this with the vesrion in lonprintout,
10356: 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
10357: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10358:
10359: At least the logic that drives this has been pulled out into loncommon.
10360:
10361:
10362:
10363: ssi_with_retries - Does the server side include of a resource.
10364: if the ssi call returns an error we'll retry it up to
10365: the number of times requested by the caller.
10366: If we still have a proble, no text is appended to the
10367: output and we set some global variables.
10368: to indicate to the caller an SSI error occurred.
10369: All of this is supposed to deal with the issues described
10370: in LonCAPA BZ 5631 see:
10371: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10372: by informing the user that this happened.
10373:
10374: Parameters:
10375: resource - The resource to include. This is passed directly, without
10376: interpretation to lonnet::ssi.
10377: form - The form hash parameters that guide the interpretation of the resource
10378:
10379: retries - Number of retries allowed before giving up completely.
10380: Returns:
10381: On success, returns the rendered resource identified by the resource parameter.
10382: Side Effects:
10383: The following global variables can be set:
10384: ssi_error - If an unrecoverable error occurred this becomes true.
10385: It is up to the caller to initialize this to false
10386: if desired.
10387: ssi_error_resource - If an unrecoverable error occurred, this is the value
10388: of the resource that could not be rendered by the ssi
10389: call.
10390: ssi_error_message - The error string fetched from the ssi response
10391: in the event of an error.

10398: =head1 SUBROUTINES
10399:
10400: =over
10401:
10402: =head1 Routines to display previous version of a Task for a specific student
10403:
10404: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10405: can receive another opportunity. Access to tasks is slot-based. If a slot
10406: requires a proctor to check-in the student, a new version of the Task will
10407: be created when the student is checked in to the new opportunity.
10408:
10409: If a particular student has tried two or more versions of a particular task,
10410: the submission screen provides a user with vgr privileges (e.g., a Course
10411: Coordinator) the ability to display a previous version worked on by the
10412: student. By default, the current version is displayed. If a previous version
10413: has been selected for display, submission data are only shown that pertain
10414: to that particular version, and the interface to submit grades is not shown.
10415:
10416: =over 4
10417:
10418: =item show_previous_task_version()
10419:
10420: Displays a specified version of a student's Task, as the student sees it.
10421:
10422: Inputs: 2
10423: request - request object
10424: symb - unique symb for current instance of resource
10425:
10426: Output: None.
