5553: =head1 Bubble sheet grading routines
5554:
5555: For this documentation:
5556:
5557: 'scanline' refers to the full line of characters
5558: from the file that we are parsing that represents one entire sheet
5559:
5560: 'bubble line' refers to the data
5561: representing the line of bubbles that are on the physical bubblesheet
5562:
5563:
5564: The overall process is that a scanned in bubblesheet data is uploaded
5565: into a course. When a user wants to grade, they select a
5566: sequence/folder of resources, a file of bubblesheet info, and pick
5567: one of the predefined configurations for what each scanline looks
5568: like.
5569:
5570: Next each scanline is checked for any errors of either 'missing
5571: bubbles' (it's an error because it may have been mis-scanned
5572: because too light bubbling), 'double bubble' (each bubble line should
5573: have no more than one letter picked), invalid or duplicated CODE,
5574: invalid student/employee ID
5575:
5576: If the CODE option is used that determines the randomization of the
5577: homework problems, either way the student/employee ID is looked up into a
5578: username:domain.
5579:
5580: During the validation phase the instructor can choose to skip scanlines.
5581:
5582: After the validation phase, there are now 3 bubblesheet files
5583:
5584: scantron_original_filename (unmodified original file)
5585: scantron_corrected_filename (file where the corrected information has replaced the original information)
5586: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5587:
5588: Also there is a separate hash nohist_scantrondata that contains extra
5589: correction information that isn't representable in the bubblesheet
5590: file (see &scantron_getfile() for more information)
5591:
5592: After all scanlines are either valid, marked as valid or skipped, then
5593: foreach line foreach problem in the picked sequence, an ssi request is
5594: made that simulates a user submitting their selected letter(s) against
5595: the homework problem.

6369:
6370: Arguments:
6371: line - The text of the bubblesheet file line to process
6372: whichline - Line number
6373: scantron_config - Hash describing the format of the bubblesheet lines.
6374: scan_data - Hash of extra information about the scanline
6375: (see scantron_getfile for more information)
6376: just_header - True if should not process question answers but only
6377: the stuff to the left of the answers.
6378: randomorder - True if randomorder in use
6379: randompick - True if randompick in use
6380: sequence - Exam folder URL
6381: master_seq - Ref to array containing symbs in exam folder
6382: symb_to_resource - Ref to hash of symbs for resources in exam folder
6383: (corresponding values are resource objects)
6384: partids_by_symb - Ref to hash of symb -> array ref of partIDs
6385: orderedforcode - Ref to hash of arrays. keys are CODEs and values
6386: are refs to an array of resource objects, ordered
6387: according to order used for CODE, when randomorder
6388: and or randompick are in use.
6389: respnumlookup - Ref to hash mapping question numbers in bubble lines
6390: for current line to question number used for same question
6391: in "Master Sequence" (as seen by Course Coordinator).
6392: startline - Ref to hash where key is question number (0 is first)
6393: and value is number of first bubble line for current
6394: student or code-based randompick and/or randomorder.
6395: totalref - Ref of scalar used to score total number of bubble
6396: lines needed for responses in a scan line (used when
6397: randompick in use.
6398:
6399: Returns:
6400: Hash containing the result of parsing the scanline
6401:
6402: Keys are all proceeded by the string 'scantron.'
6403:
6404: CODE - the CODE in use for this scanline
6405: useCODE - 1 if the CODE is invalid but it usage has been forced
6406: by the operator
6407: CODE_ignore_dup - 1 if the CODE is a duplicated use when unique
6408: CODEs were selected, but the usage has been
6409: forced by the operator
6410: ID - student/employee ID
6411: PaperID - if used, the ID number printed on the sheet when the
6412: paper was scanned
6413: FirstName - first name from the sheet

6422: to a single question that have more than one bubble filled in.
6423: Of the form questionnumber::firstbubblenumber:count
6424:
6425: In the above, count is the number of bubble responses in the
6426: input line needed to represent the possible answers to the question.
6427: e.g. a radioresponse with 15 choices in an answer sheet with 10 choices
6428: per line would have count = 2.
6429:
6430: maxquest - the number of the last bubble line that was parsed
6431:
6432: (<number> starts at 1)
6433: <number>.answer - zero or more letters representing the selected
6434: letters from the scanline for the bubble line
6435: <number>.
6436: if blank there was either no bubble or there where
6437: multiple bubbles, (consult the keys missingerror and

10877:
10878: Apache::grades
10879:
10880: =head1 SYNOPSIS
10881:
10882: Handles the viewing of grades.
10883:
10884: This is part of the LearningOnline Network with CAPA project
10885: described at http://www.lon-capa.org.
10886:
10887: =head1 OVERVIEW
10888:
10889: Do an ssi with retries:
10890: While I'd love to factor out this with the version in lonprintout,
10891: 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
10892: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10893:
10894: At least the logic that drives this has been pulled out into loncommon.
10895:
10896:
10897:
10898: ssi_with_retries - Does the server side include of a resource.
10899: if the ssi call returns an error we'll retry it up to
10900: the number of times requested by the caller.
10901: If we still have a problem, no text is appended to the
10902: output and we set some global variables.
10903: to indicate to the caller an SSI error occurred.
10904: All of this is supposed to deal with the issues described
10905: in LON-CAPA BZ 5631 see:
10906: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10907: by informing the user that this happened.
10908:
10909: Parameters:
10910: resource - The resource to include. This is passed directly, without
10911: interpretation to lonnet::ssi.
10912: form - The form hash parameters that guide the interpretation of the resource
10913:
10914: retries - Number of retries allowed before giving up completely.
10915: Returns:
10916: On success, returns the rendered resource identified by the resource parameter.
10917: Side Effects:
10918: The following global variables can be set:
10919: ssi_error - If an unrecoverable error occurred this becomes true.
10920: It is up to the caller to initialize this to false
10921: if desired.
10922: ssi_error_resource - If an unrecoverable error occurred, this is the value
10923: of the resource that could not be rendered by the ssi
10924: call.
10925: ssi_error_message - The error string fetched from the ssi response
10926: in the event of an error.

10936:
10937: =head1 Routines to display previous version of a Task for a specific student
10938:
10939: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10940: can receive another opportunity. Access to tasks is slot-based. If a slot
10941: requires a proctor to check-in the student, a new version of the Task will
10942: be created when the student is checked in to the new opportunity.
10943:
10944: If a particular student has tried two or more versions of a particular task,
10945: the submission screen provides a user with vgr privileges (e.g., a Course
10946: Coordinator) the ability to display a previous version worked on by the
10947: student. By default, the current version is displayed. If a previous version
10948: has been selected for display, submission data are only shown that pertain
10949: to that particular version, and the interface to submit grades is not shown.
10950:
10951: =over 4
10952:
10953: =item show_previous_task_version()

10959: symb - unique symb for current instance of resource
10960:
10961: Output: None.
10962:
10963: Side Effects: calls &show_problem() to print version of Task, with
10964: version contained in form item: $env{'form.previousversion'}
10965:
10966: =item choose_task_version_form()
10967:
10968: Displays a web form used to select which version of a student's view of a
10969: Task should be displayed. Either launches a pop-up window, or replaces
10970: content in existing pop-up, or replaces page in main window.

10977: breadcrumbs etc., are displayed
10978:
10979: Output: 4
10980: current - student's current version
10981: displayed - student's version being displayed
10982: result - scalar containing HTML for web form used to switch to
10983: a different version (or a link to close window, if pop-up).
10984: js - javascript for processing selection in versions web form
10985:
10986: Side Effects: None.
10987:
10988: =item previous_display_javascript()
10989:
10990: Inputs: 2
10991: nomenu - 1 if display is in a pop-up window, and hence no menu
10992: breadcrumbs etc., are displayed.
10993: current - student's current version number.
10994:
10995: Output: 1
10996: js - javascript for processing selection in versions web form.
