4889: =head1 Bubble sheet grading routines
4890:
4891: For this documentation:
4892:
4893: 'scanline' refers to the full line of characters
4894: from the file that we are parsing that represents one entire sheet
4895:
4896: 'bubble line' refers to the data
4897: representing the line of bubbles that are on the physical bubble sheet
4898:
4899:
4900: The overall process is that a scanned in bubble sheet data is uploaded
4901: into a course. When a user wants to grade, they select a
4902: sequence/folder of resources, a file of bubble sheet info, and pick
4903: one of the predefined configurations for what each scanline looks
4904: like.
4905:
4906: Next each scanline is checked for any errors of either 'missing
4907: bubbles' (it's an error because it may have been mis-scanned
4908: because too light bubbling), 'double bubble' (each bubble line should
4909: have no more that one letter picked), invalid or duplicated CODE,
4910: invalid student/employee ID
4911:
4912: If the CODE option is used that determines the randomization of the
4913: homework problems, either way the student/employee ID is looked up into a
4914: username:domain.
4915:
4916: During the validation phase the instructor can choose to skip scanlines.
4917:
4918: After the validation phase, there are now 3 bubble sheet files
4919:
4920: scantron_original_filename (unmodified original file)
4921: scantron_corrected_filename (file where the corrected information has replaced the original information)
4922: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4923:
4924: Also there is a separate hash nohist_scantrondata that contains extra
4925: correction information that isn't representable in the bubble sheet
4926: file (see &scantron_getfile() for more information)
4927:
4928: After all scanlines are either valid, marked as valid or skipped, then
4929: foreach line foreach problem in the picked sequence, an ssi request is
4930: made that simulates a user submitting their selected letter(s) against
4931: the homework problem.

9512:
9513: Apache::grades
9514:
9515: =head1 SYNOPSIS
9516:
9517: Handles the viewing of grades.
9518:
9519: This is part of the LearningOnline Network with CAPA project
9520: described at http://www.lon-capa.org.
9521:
9522: =head1 OVERVIEW
9523:
9524: Do an ssi with retries:
9525: While I'd love to factor out this with the vesrion in lonprintout,
9526: 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
9527: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9528:
9529: At least the logic that drives this has been pulled out into loncommon.
9530:
9531:
9532:
9533: ssi_with_retries - Does the server side include of a resource.
9534: if the ssi call returns an error we'll retry it up to
9535: the number of times requested by the caller.
9536: If we still have a proble, no text is appended to the
9537: output and we set some global variables.
9538: to indicate to the caller an SSI error occurred.
9539: All of this is supposed to deal with the issues described
9540: in LonCAPA BZ 5631 see:
9541: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9542: by informing the user that this happened.
9543:
9544: Parameters:
9545: resource - The resource to include. This is passed directly, without
9546: interpretation to lonnet::ssi.
9547: form - The form hash parameters that guide the interpretation of the resource
9548:
9549: retries - Number of retries allowed before giving up completely.
9550: Returns:
9551: On success, returns the rendered resource identified by the resource parameter.
9552: Side Effects:
9553: The following global variables can be set:
9554: ssi_error - If an unrecoverable error occurred this becomes true.
9555: It is up to the caller to initialize this to false
9556: if desired.
9557: ssi_error_resource - If an unrecoverable error occurred, this is the value
9558: of the resource that could not be rendered by the ssi
9559: call.
9560: ssi_error_message - The error string fetched from the ssi response
9561: in the event of an error.

9571:
9572: =item scantron_get_correction() :
9573:
9574: Builds the interface screen to interact with the operator to fix a
9575: specific error condition in a specific scanline
9576:
9577: Arguments:
9578: $r - Apache request object
9579: $i - number of the current scanline
9580: $scan_record - hash ref as returned from &scantron_parse_scanline()
9581: $scan_config - hash ref as returned from &get_scantron_config()
9582: $line - full contents of the current scanline
9583: $error - error condition, valid values are
9584: 'incorrectCODE', 'duplicateCODE',
9585: 'doublebubble', 'missingbubble',
9586: 'duplicateID', 'incorrectID'
9587: $arg - extra information needed
9588: For errors:
9589: - duplicateID - paper number that this studentID was seen before on
9590: - duplicateCODE - array ref of the paper numbers this CODE was
9591: seen on before
9592: - incorrectCODE - current incorrect CODE
9593: - doublebubble - array ref of the bubble lines that have double
9594: bubble errors
9595: - missingbubble - array ref of the bubble lines that have missing
9596: bubble errors
9597:
9598: =item scantron_get_maxbubble() :
9599:
9600: Arguments:
9601: $nav_error - Reference to scalar which is a flag to indicate a
9602: failure to retrieve a navmap object.
9603: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9604: calling routine should trap the error condition and display the warning
9605: found in &navmap_errormsg().
9606:
9607: Returns the maximum number of bubble lines that are expected to
9608: occur. Does this by walking the selected sequence rendering the
9609: resource and then checking &Apache::lonxml::get_problem_counter()
9610: for what the current value of the problem counter is.
9611:
9612: Caches the results to $env{'form.scantron_maxbubble'},
9613: $env{'form.scantron.bubble_lines.n'},
9614: $env{'form.scantron.first_bubble_line.n'} and
9615: $env{"form.scantron.sub_bubblelines.n"}
9616: which are the total number of bubble, lines, the number of bubble
9617: lines for response n and number of the first bubble line for response n,
9618: and a comma separated list of numbers of bubble lines for sub-questions
9619: (for optionresponse, matchresponse, and rankresponse items), for response n.
9620:
9621:
9622: =item scantron_validate_missingbubbles() :
9623:
9624: Validates all scanlines in the selected file to not have any
9625: answers that don't have bubbles that have not been verified
9626: to be bubble free.
9627:
9628: =item scantron_process_students() :
9629:
9630: Routine that does the actual grading of the bubble sheet information.
9631:
9632: The parsed scanline hash is added to %env
9633:
9634: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9635: foreach resource , with the form data of
9636:
9637: 'submitted' =>'scantron'
9638: 'grade_target' =>'grade',
9639: 'grade_username'=> username of student
9640: 'grade_domain' => domain of student
9641: 'grade_courseid'=> of course
9642: 'grade_symb' => symb of resource to grade
9643:
9644: This triggers a grading pass. The problem grading code takes care
9645: of converting the bubbled letter information (now in %env) into a
9646: valid submission.
9647:
9648: =item scantron_upload_scantron_data() :
9649:
9650: Creates the screen for adding a new bubble sheet data file to a course.
9651:
9652: =item scantron_upload_scantron_data_save() :
9653:
9654: Adds a provided bubble information data file to the course if user
9655: has the correct privileges to do so.
9656:
9657: =item valid_file() :
9658:
9659: Validates that the requested bubble data file exists in the course.
9660:
9661: =item scantron_download_scantron_data() :
9662:
9663: Shows a list of the three internal files (original, corrected,
9664: skipped) for a specific bubble sheet data file that exists in the
9665: course.
9666:
9667: =item scantron_validate_ID() :
9668:
9669: Validates all scanlines in the selected file to not have any
9670: invalid or underspecified student/employee IDs
9671:
9672: =item navmap_errormsg() :
9673:
9674: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9675: Should be called whenever the request to instantiate a navmap object fails.
