5080: =head1 Bubble sheet grading routines
5081:
5082: For this documentation:
5083:
5084: 'scanline' refers to the full line of characters
5085: from the file that we are parsing that represents one entire sheet
5086:
5087: 'bubble line' refers to the data
5088: representing the line of bubbles that are on the physical bubblesheet
5089:
5090:
5091: The overall process is that a scanned in bubblesheet data is uploaded
5092: into a course. When a user wants to grade, they select a
5093: sequence/folder of resources, a file of bubblesheet info, and pick
5094: one of the predefined configurations for what each scanline looks
5095: like.
5096:
5097: Next each scanline is checked for any errors of either 'missing
5098: bubbles' (it's an error because it may have been mis-scanned
5099: because too light bubbling), 'double bubble' (each bubble line should
5100: have no more than one letter picked), invalid or duplicated CODE,
5101: invalid student/employee ID
5102:
5103: If the CODE option is used that determines the randomization of the
5104: homework problems, either way the student/employee ID is looked up into a
5105: username:domain.
5106:
5107: During the validation phase the instructor can choose to skip scanlines.
5108:
5109: After the validation phase, there are now 3 bubblesheet files
5110:
5111: scantron_original_filename (unmodified original file)
5112: scantron_corrected_filename (file where the corrected information has replaced the original information)
5113: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5114:
5115: Also there is a separate hash nohist_scantrondata that contains extra
5116: correction information that isn't representable in the bubblesheet
5117: file (see &scantron_getfile() for more information)
5118:
5119: After all scanlines are either valid, marked as valid or skipped, then
5120: foreach line foreach problem in the picked sequence, an ssi request is
5121: made that simulates a user submitting their selected letter(s) against
5122: the homework problem.

5906: startline - Ref to hash where key is question number (0 is first)
5907: and value is number of first bubble line for current
5908: student or code-based randompick and/or randomorder.
5909: totalref - Ref of scalar used to score total number of bubble
5910: lines needed for responses in a scan line (used when
5911: randompick in use.
5912:
5913: Returns:
5914: Hash containing the result of parsing the scanline
5915:
5916: Keys are all proceeded by the string 'scantron.'
5917:
5918: CODE - the CODE in use for this scanline
5919: useCODE - 1 if the CODE is invalid but it usage has been forced
5920: by the operator
5921: CODE_ignore_dup - 1 if the CODE is a duplicated use when unique
5922: CODEs were selected, but the usage has been
5923: forced by the operator
5924: ID - student/employee ID
5925: PaperID - if used, the ID number printed on the sheet when the
5926: paper was scanned
5927: FirstName - first name from the sheet
5928: LastName - last name from the sheet
5929:
5930: if just_header was not true these key may also exist
5931:
5932: missingerror - a list of bubble ranges that are considered to be answers
5933: to a single question that don't have any bubbles filled in.
5934: Of the form questionnumber:firstbubblenumber:count.
5935: doubleerror - a list of bubble ranges that are considered to be answers
5936: to a single question that have more than one bubble filled in.
5937: Of the form questionnumber::firstbubblenumber:count
5938:
5939: In the above, count is the number of bubble responses in the
5940: input line needed to represent the possible answers to the question.
5941: e.g. a radioresponse with 15 choices in an answer sheet with 10 choices
5942: per line would have count = 2.
5943:
5944: maxquest - the number of the last bubble line that was parsed
5945:
5946: (<number> starts at 1)
5947: <number>.answer - zero or more letters representing the selected
5948: letters from the scanline for the bubble line
5949: <number>.
5950: if blank there was either no bubble or there where
5951: multiple bubbles, (consult the keys missingerror and
5952: doubleerror if this is an error condition)

10351: =head1 NAME
10352:
10353: Apache::grades
10354:
10355: =head1 SYNOPSIS
10356:
10357: Handles the viewing of grades.
10358:
10359: This is part of the LearningOnline Network with CAPA project
10360: described at http://www.lon-capa.org.
10361:
10362: =head1 OVERVIEW
10363:
10364: Do an ssi with retries:
10365: While I'd love to factor out this with the vesrion in lonprintout,
10366: 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
10367: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10368:
10369: At least the logic that drives this has been pulled out into loncommon.
10370:
10371:
10372:
10373: ssi_with_retries - Does the server side include of a resource.
10374: if the ssi call returns an error we'll retry it up to
10375: the number of times requested by the caller.
10376: If we still have a proble, no text is appended to the
10377: output and we set some global variables.
10378: to indicate to the caller an SSI error occurred.
10379: All of this is supposed to deal with the issues described
10380: in LonCAPA BZ 5631 see:
10381: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10382: by informing the user that this happened.
10383:
10384: Parameters:
10385: resource - The resource to include. This is passed directly, without
10386: interpretation to lonnet::ssi.
10387: form - The form hash parameters that guide the interpretation of the resource
10388:
10389: retries - Number of retries allowed before giving up completely.
10390: Returns:
10391: On success, returns the rendered resource identified by the resource parameter.
10392: Side Effects:
10393: The following global variables can be set:
10394: ssi_error - If an unrecoverable error occurred this becomes true.
10395: It is up to the caller to initialize this to false
10396: if desired.
10397: ssi_error_resource - If an unrecoverable error occurred, this is the value
10398: of the resource that could not be rendered by the ssi
10399: call.
10400: ssi_error_message - The error string fetched from the ssi response
10401: in the event of an error.

10408: =head1 SUBROUTINES
10409:
10410: =over
10411:
10412: =head1 Routines to display previous version of a Task for a specific student
10413:
10414: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10415: can receive another opportunity. Access to tasks is slot-based. If a slot
10416: requires a proctor to check-in the student, a new version of the Task will
10417: be created when the student is checked in to the new opportunity.
10418:
10419: If a particular student has tried two or more versions of a particular task,
10420: the submission screen provides a user with vgr privileges (e.g., a Course
10421: Coordinator) the ability to display a previous version worked on by the
10422: student. By default, the current version is displayed. If a previous version
10423: has been selected for display, submission data are only shown that pertain
10424: to that particular version, and the interface to submit grades is not shown.
10425:
10426: =over 4
10427:
10428: =item show_previous_task_version()
10429:
10430: Displays a specified version of a student's Task, as the student sees it.
10431:
10432: Inputs: 2
10433: request - request object
10434: symb - unique symb for current instance of resource
10435:
10436: Output: None.
10437:
10438: Side Effects: calls &show_problem() to print version of Task, with
10439: version contained in form item: $env{'form.previousversion'}
10440:
10441: =item choose_task_version_form()
10442:
10443: Displays a web form used to select which version of a student's view of a
