5552: =head1 Bubble sheet grading routines
5553:
5554: For this documentation:
5555:
5556: 'scanline' refers to the full line of characters
5557: from the file that we are parsing that represents one entire sheet
5558:
5559: 'bubble line' refers to the data
5560: representing the line of bubbles that are on the physical bubblesheet
5561:
5562:
5563: The overall process is that a scanned in bubblesheet data is uploaded
5564: into a course. When a user wants to grade, they select a
5565: sequence/folder of resources, a file of bubblesheet info, and pick
5566: one of the predefined configurations for what each scanline looks
5567: like.
5568:
5569: Next each scanline is checked for any errors of either 'missing
5570: bubbles' (it's an error because it may have been mis-scanned
5571: because too light bubbling), 'double bubble' (each bubble line should
5572: have no more than one letter picked), invalid or duplicated CODE,
5573: invalid student/employee ID
5574:
5575: If the CODE option is used that determines the randomization of the
5576: homework problems, either way the student/employee ID is looked up into a
5577: username:domain.
5578:
5579: During the validation phase the instructor can choose to skip scanlines.
5580:
5581: After the validation phase, there are now 3 bubblesheet files
5582:
5583: scantron_original_filename (unmodified original file)
5584: scantron_corrected_filename (file where the corrected information has replaced the original information)
5585: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5586:
5587: Also there is a separate hash nohist_scantrondata that contains extra
5588: correction information that isn't representable in the bubblesheet
5589: file (see &scantron_getfile() for more information)
5590:
5591: After all scanlines are either valid, marked as valid or skipped, then
5592: foreach line foreach problem in the picked sequence, an ssi request is
5593: made that simulates a user submitting their selected letter(s) against
5594: the homework problem.

6368:
6369: Arguments:
6370: line - The text of the bubblesheet file line to process
6371: whichline - Line number
6372: scantron_config - Hash describing the format of the bubblesheet lines.
6373: scan_data - Hash of extra information about the scanline
6374: (see scantron_getfile for more information)
6375: just_header - True if should not process question answers but only
6376: the stuff to the left of the answers.
6377: randomorder - True if randomorder in use
6378: randompick - True if randompick in use
6379: sequence - Exam folder URL
6380: master_seq - Ref to array containing symbs in exam folder
6381: symb_to_resource - Ref to hash of symbs for resources in exam folder
6382: (corresponding values are resource objects)
6383: partids_by_symb - Ref to hash of symb -> array ref of partIDs
6384: orderedforcode - Ref to hash of arrays. keys are CODEs and values
6385: are refs to an array of resource objects, ordered
6386: according to order used for CODE, when randomorder
6387: and or randompick are in use.
6388: respnumlookup - Ref to hash mapping question numbers in bubble lines
6389: for current line to question number used for same question
6390: in "Master Sequence" (as seen by Course Coordinator).
6391: startline - Ref to hash where key is question number (0 is first)
6392: and value is number of first bubble line for current
6393: student or code-based randompick and/or randomorder.
6394: totalref - Ref of scalar used to score total number of bubble
6395: lines needed for responses in a scan line (used when
6396: randompick in use.
6397:
6398: Returns:
6399: Hash containing the result of parsing the scanline
6400:
6401: Keys are all proceeded by the string 'scantron.'
6402:
6403: CODE - the CODE in use for this scanline
6404: useCODE - 1 if the CODE is invalid but it usage has been forced
6405: by the operator
6406: CODE_ignore_dup - 1 if the CODE is a duplicated use when unique
6407: CODEs were selected, but the usage has been
6408: forced by the operator
6409: ID - student/employee ID
6410: PaperID - if used, the ID number printed on the sheet when the
6411: paper was scanned
6412: FirstName - first name from the sheet

6421: to a single question that have more than one bubble filled in.
6422: Of the form questionnumber::firstbubblenumber:count
6423:
6424: In the above, count is the number of bubble responses in the
6425: input line needed to represent the possible answers to the question.
6426: e.g. a radioresponse with 15 choices in an answer sheet with 10 choices
6427: per line would have count = 2.
6428:
6429: maxquest - the number of the last bubble line that was parsed
6430:
6431: (<number> starts at 1)
6432: <number>.answer - zero or more letters representing the selected
6433: letters from the scanline for the bubble line
6434: <number>.
6435: if blank there was either no bubble or there where
6436: multiple bubbles, (consult the keys missingerror and

10876:
10877: Apache::grades
10878:
10879: =head1 SYNOPSIS
10880:
10881: Handles the viewing of grades.
10882:
10883: This is part of the LearningOnline Network with CAPA project
10884: described at http://www.lon-capa.org.
10885:
10886: =head1 OVERVIEW
10887:
10888: Do an ssi with retries:
10889: While I'd love to factor out this with the version in lonprintout,
10890: 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
10891: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10892:
10893: At least the logic that drives this has been pulled out into loncommon.
10894:
10895:
10896:
10897: ssi_with_retries - Does the server side include of a resource.
10898: if the ssi call returns an error we'll retry it up to
10899: the number of times requested by the caller.
10900: If we still have a problem, no text is appended to the
10901: output and we set some global variables.
10902: to indicate to the caller an SSI error occurred.
10903: All of this is supposed to deal with the issues described
10904: in LON-CAPA BZ 5631 see:
10905: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10906: by informing the user that this happened.
10907:
10908: Parameters:
10909: resource - The resource to include. This is passed directly, without
10910: interpretation to lonnet::ssi.
10911: form - The form hash parameters that guide the interpretation of the resource
10912:
10913: retries - Number of retries allowed before giving up completely.
10914: Returns:
10915: On success, returns the rendered resource identified by the resource parameter.
10916: Side Effects:
10917: The following global variables can be set:
10918: ssi_error - If an unrecoverable error occurred this becomes true.
10919: It is up to the caller to initialize this to false
10920: if desired.
10921: ssi_error_resource - If an unrecoverable error occurred, this is the value
10922: of the resource that could not be rendered by the ssi
10923: call.
10924: ssi_error_message - The error string fetched from the ssi response
10925: in the event of an error.

10935:
10936: =head1 Routines to display previous version of a Task for a specific student
10937:
10938: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10939: can receive another opportunity. Access to tasks is slot-based. If a slot
10940: requires a proctor to check-in the student, a new version of the Task will
10941: be created when the student is checked in to the new opportunity.
10942:
10943: If a particular student has tried two or more versions of a particular task,
10944: the submission screen provides a user with vgr privileges (e.g., a Course
10945: Coordinator) the ability to display a previous version worked on by the
10946: student. By default, the current version is displayed. If a previous version
10947: has been selected for display, submission data are only shown that pertain
10948: to that particular version, and the interface to submit grades is not shown.
10949:
10950: =over 4
10951:
10952: =item show_previous_task_version()

10958: symb - unique symb for current instance of resource
10959:
10960: Output: None.
10961:
10962: Side Effects: calls &show_problem() to print version of Task, with
10963: version contained in form item: $env{'form.previousversion'}
10964:
10965: =item choose_task_version_form()
10966:
10967: Displays a web form used to select which version of a student's view of a

10979: current - student's current version
10980: displayed - student's version being displayed
10981: result - scalar containing HTML for web form used to switch to
10982: a different version (or a link to close window, if pop-up).
10983: js - javascript for processing selection in versions web form
10984:
10985: Side Effects: None.
10986:
10987: =item previous_display_javascript()
10988:
10989: Inputs: 2
10990: nomenu - 1 if display is in a pop-up window, and hence no menu
10991: breadcrumbs etc., are displayed.
10992: current - student's current version number.
10993:
10994: Output: 1
10995: js - javascript for processing selection in versions web form.
