4782:
1.424 albertel 4783: For this documentation:
4784:
4785: 'scanline' refers to the full line of characters
4786: from the file that we are parsing that represents one entire sheet
4787:
4788: 'bubble line' refers to the data
4789: representing the line of bubbles that are on the physical bubble sheet
4790:
4791:
4792: The overall process is that a scanned in bubble sheet data is uploaded
4793: into a course. When a user wants to grade, they select a
4794: sequence/folder of resources, a file of bubble sheet info, and pick
4795: one of the predefined configurations for what each scanline looks
4796: like.
4797:
4798: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4799: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4800: because too light bubbling), 'double bubble' (each bubble line should
4801: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4802: invalid student/employee ID
1.424 albertel 4803:
4804: If the CODE option is used that determines the randomization of the
1.556 weissno 4805: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4806: username:domain.
4807:
4808: During the validation phase the instructor can choose to skip scanlines.
4809:
1.435 foxr 4810: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4811:
4812: scantron_original_filename (unmodified original file)
4813: scantron_corrected_filename (file where the corrected information has replaced the original information)
4814: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4815:
4816: Also there is a separate hash nohist_scantrondata that contains extra
4817: correction information that isn't representable in the bubble sheet
4818: file (see &scantron_getfile() for more information)
4819:
4820: After all scanlines are either valid, marked as valid or skipped, then
4821: foreach line foreach problem in the picked sequence, an ssi request is
4822: made that simulates a user submitting their selected letter(s) against
4823: the homework problem.

9416: =head1 NAME
9417:
9418: Apache::grades
9419:
9420: =head1 SYNOPSIS
9421:
9422: Handles the viewing of grades.
9423:
9424: This is part of the LearningOnline Network with CAPA project
9425: described at http://www.lon-capa.org.
9426:
9427: =head1 OVERVIEW
9428:
9429: Do an ssi with retries:
9430: While I'd love to factor out this with the vesrion in lonprintout,
9431: 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
9432: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9433:
9434: At least the logic that drives this has been pulled out into loncommon.
9435:
9436:
9437:
9438: ssi_with_retries - Does the server side include of a resource.
9439: if the ssi call returns an error we'll retry it up to
9440: the number of times requested by the caller.
9441: If we still have a proble, no text is appended to the
9442: output and we set some global variables.
9443: to indicate to the caller an SSI error occurred.
9444: All of this is supposed to deal with the issues described
9445: in LonCAPA BZ 5631 see:
9446: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9447: by informing the user that this happened.
9448:
9449: Parameters:
9450: resource - The resource to include. This is passed directly, without
9451: interpretation to lonnet::ssi.
9452: form - The form hash parameters that guide the interpretation of the resource
9453:
9454: retries - Number of retries allowed before giving up completely.
9455: Returns:
9456: On success, returns the rendered resource identified by the resource parameter.
9457: Side Effects:
9458: The following global variables can be set:
9459: ssi_error - If an unrecoverable error occurred this becomes true.
9460: It is up to the caller to initialize this to false
9461: if desired.
9462: ssi_error_resource - If an unrecoverable error occurred, this is the value
9463: of the resource that could not be rendered by the ssi
9464: call.
9465: ssi_error_message - The error string fetched from the ssi response
9466: in the event of an error.

9477: =item scantron_get_correction() :
9478:
9479: Builds the interface screen to interact with the operator to fix a
9480: specific error condition in a specific scanline
9481:
9482: Arguments:
9483: $r - Apache request object
9484: $i - number of the current scanline
9485: $scan_record - hash ref as returned from &scantron_parse_scanline()
9486: $scan_config - hash ref as returned from &get_scantron_config()
9487: $line - full contents of the current scanline
9488: $error - error condition, valid values are
9489: 'incorrectCODE', 'duplicateCODE',
9490: 'doublebubble', 'missingbubble',
9491: 'duplicateID', 'incorrectID'
9492: $arg - extra information needed
9493: For errors:
9494: - duplicateID - paper number that this studentID was seen before on
9495: - duplicateCODE - array ref of the paper numbers this CODE was
9496: seen on before
9497: - incorrectCODE - current incorrect CODE
9498: - doublebubble - array ref of the bubble lines that have double
9499: bubble errors
9500: - missingbubble - array ref of the bubble lines that have missing
9501: bubble errors
9502:
9503: =item scantron_get_maxbubble() :
9504:
1.582 raeburn 9505: Arguments:
9506: $nav_error - Reference to scalar which is a flag to indicate a
9507: failure to retrieve a navmap object.
9508: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9509: calling routine should trap the error condition and display the warning
9510: found in &navmap_errormsg().
9511:
1.531 jms 9512: Returns the maximum number of bubble lines that are expected to
9513: occur. Does this by walking the selected sequence rendering the
9514: resource and then checking &Apache::lonxml::get_problem_counter()
9515: for what the current value of the problem counter is.
9516:
9517: Caches the results to $env{'form.scantron_maxbubble'},
9518: $env{'form.scantron.bubble_lines.n'},
9519: $env{'form.scantron.first_bubble_line.n'} and
9520: $env{"form.scantron.sub_bubblelines.n"}
9521: which are the total number of bubble, lines, the number of bubble
9522: lines for response n and number of the first bubble line for response n,
9523: and a comma separated list of numbers of bubble lines for sub-questions
9524: (for optionresponse, matchresponse, and rankresponse items), for response n.

9527: =item scantron_validate_missingbubbles() :

9531: to be bubble free.
9532:
9533: =item scantron_process_students() :
9534:
9535: Routine that does the actual grading of the bubble sheet information.
9536:
9537: The parsed scanline hash is added to %env
9538:
9539: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9540: foreach resource , with the form data of
9541:
9542: 'submitted' =>'scantron'
9543: 'grade_target' =>'grade',
9544: 'grade_username'=> username of student
9545: 'grade_domain' => domain of student
9546: 'grade_courseid'=> of course
9547: 'grade_symb' => symb of resource to grade
9548:
9549: This triggers a grading pass. The problem grading code takes care
9550: of converting the bubbled letter information (now in %env) into a
9551: valid submission.
9552:
9553: =item scantron_upload_scantron_data() :

9570: course.
9571:
9572: =item scantron_validate_ID() :
