4779:
1.424 albertel 4780: For this documentation:
4781:
4782: 'scanline' refers to the full line of characters
4783: from the file that we are parsing that represents one entire sheet
4784:
4785: 'bubble line' refers to the data
4786: representing the line of bubbles that are on the physical bubble sheet
4787:
4788:
4789: The overall process is that a scanned in bubble sheet data is uploaded
4790: into a course. When a user wants to grade, they select a
4791: sequence/folder of resources, a file of bubble sheet info, and pick
4792: one of the predefined configurations for what each scanline looks
4793: like.
4794:
4795: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4796: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4797: because too light bubbling), 'double bubble' (each bubble line should
4798: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4799: invalid student/employee ID
1.424 albertel 4800:
4801: If the CODE option is used that determines the randomization of the
1.556 weissno 4802: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4803: username:domain.
4804:
4805: During the validation phase the instructor can choose to skip scanlines.
4806:
1.435 foxr 4807: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4808:
4809: scantron_original_filename (unmodified original file)
4810: scantron_corrected_filename (file where the corrected information has replaced the original information)
4811: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4812:
4813: Also there is a separate hash nohist_scantrondata that contains extra
4814: correction information that isn't representable in the bubble sheet
4815: file (see &scantron_getfile() for more information)
4816:
4817: After all scanlines are either valid, marked as valid or skipped, then
4818: foreach line foreach problem in the picked sequence, an ssi request is
4819: made that simulates a user submitting their selected letter(s) against
4820: the homework problem.

9407: =head1 NAME
9408:
9409: Apache::grades
9410:
9411: =head1 SYNOPSIS
9412:
9413: Handles the viewing of grades.
9414:
9415: This is part of the LearningOnline Network with CAPA project
9416: described at http://www.lon-capa.org.
9417:
9418: =head1 OVERVIEW
9419:
9420: Do an ssi with retries:
9421: While I'd love to factor out this with the vesrion in lonprintout,
9422: 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
9423: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9424:
9425: At least the logic that drives this has been pulled out into loncommon.
9426:
9427:
9428:
9429: ssi_with_retries - Does the server side include of a resource.
9430: if the ssi call returns an error we'll retry it up to
9431: the number of times requested by the caller.
9432: If we still have a proble, no text is appended to the
9433: output and we set some global variables.
9434: to indicate to the caller an SSI error occurred.
9435: All of this is supposed to deal with the issues described
9436: in LonCAPA BZ 5631 see:
9437: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9438: by informing the user that this happened.
9439:
9440: Parameters:
9441: resource - The resource to include. This is passed directly, without
9442: interpretation to lonnet::ssi.
9443: form - The form hash parameters that guide the interpretation of the resource
9444:
9445: retries - Number of retries allowed before giving up completely.
9446: Returns:
9447: On success, returns the rendered resource identified by the resource parameter.
9448: Side Effects:
9449: The following global variables can be set:
9450: ssi_error - If an unrecoverable error occurred this becomes true.
9451: It is up to the caller to initialize this to false
9452: if desired.
9453: ssi_error_resource - If an unrecoverable error occurred, this is the value
9454: of the resource that could not be rendered by the ssi
9455: call.
9456: ssi_error_message - The error string fetched from the ssi response
9457: in the event of an error.

9469:
9470: Builds the interface screen to interact with the operator to fix a
9471: specific error condition in a specific scanline
9472:
9473: Arguments:
9474: $r - Apache request object
9475: $i - number of the current scanline
9476: $scan_record - hash ref as returned from &scantron_parse_scanline()
9477: $scan_config - hash ref as returned from &get_scantron_config()
9478: $line - full contents of the current scanline
9479: $error - error condition, valid values are
9480: 'incorrectCODE', 'duplicateCODE',
9481: 'doublebubble', 'missingbubble',
9482: 'duplicateID', 'incorrectID'
9483: $arg - extra information needed
9484: For errors:
9485: - duplicateID - paper number that this studentID was seen before on
9486: - duplicateCODE - array ref of the paper numbers this CODE was
9487: seen on before
9488: - incorrectCODE - current incorrect CODE
9489: - doublebubble - array ref of the bubble lines that have double
9490: bubble errors
9491: - missingbubble - array ref of the bubble lines that have missing
9492: bubble errors
9493:
9494: =item scantron_get_maxbubble() :
9495:
1.574.2.7 raeburn 9496: Arguments:
9497: $nav_error - Reference to scalar which is a flag to indicate a
9498: failure to retrieve a navmap object.
9499: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9500: calling routine should trap the error condition and display the warning
9501: found in &navmap_errormsg().
9502:
1.531 jms 9503: Returns the maximum number of bubble lines that are expected to
9504: occur. Does this by walking the selected sequence rendering the
9505: resource and then checking &Apache::lonxml::get_problem_counter()
9506: for what the current value of the problem counter is.
9507:
9508: Caches the results to $env{'form.scantron_maxbubble'},
9509: $env{'form.scantron.bubble_lines.n'},
9510: $env{'form.scantron.first_bubble_line.n'} and
9511: $env{"form.scantron.sub_bubblelines.n"}
9512: which are the total number of bubble, lines, the number of bubble
9513: lines for response n and number of the first bubble line for response n,
9514: and a comma separated list of numbers of bubble lines for sub-questions
9515: (for optionresponse, matchresponse, and rankresponse items), for response n.

9523:
9524: =item scantron_process_students() :
9525:
9526: Routine that does the actual grading of the bubble sheet information.
9527:
9528: The parsed scanline hash is added to %env
9529:
9530: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9531: foreach resource , with the form data of
9532:
9533: 'submitted' =>'scantron'
9534: 'grade_target' =>'grade',
9535: 'grade_username'=> username of student
9536: 'grade_domain' => domain of student
9537: 'grade_courseid'=> of course
9538: 'grade_symb' => symb of resource to grade
9539:
9540: This triggers a grading pass. The problem grading code takes care
9541: of converting the bubbled letter information (now in %env) into a
9542: valid submission.

9561: course.
9562:
9563: =item scantron_validate_ID() :
