4882: =head1 Bubble sheet grading routines
4883:
1.424 albertel 4884: For this documentation:
4885:
4886: 'scanline' refers to the full line of characters
4887: from the file that we are parsing that represents one entire sheet
4888:
4889: 'bubble line' refers to the data
4890: representing the line of bubbles that are on the physical bubble sheet
4891:
4892:
4893: The overall process is that a scanned in bubble sheet data is uploaded
4894: into a course. When a user wants to grade, they select a
4895: sequence/folder of resources, a file of bubble sheet info, and pick
4896: one of the predefined configurations for what each scanline looks
4897: like.
4898:
4899: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4900: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4901: because too light bubbling), 'double bubble' (each bubble line should
4902: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4903: invalid student/employee ID
1.424 albertel 4904:
4905: If the CODE option is used that determines the randomization of the
1.556 weissno 4906: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4907: username:domain.
4908:
4909: During the validation phase the instructor can choose to skip scanlines.
4910:
1.435 foxr 4911: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4912:
4913: scantron_original_filename (unmodified original file)
4914: scantron_corrected_filename (file where the corrected information has replaced the original information)
4915: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4916:
4917: Also there is a separate hash nohist_scantrondata that contains extra
4918: correction information that isn't representable in the bubble sheet
4919: file (see &scantron_getfile() for more information)
4920:
4921: After all scanlines are either valid, marked as valid or skipped, then
4922: foreach line foreach problem in the picked sequence, an ssi request is
4923: made that simulates a user submitting their selected letter(s) against
4924: the homework problem.

9467: =head1 NAME
9468:
9469: Apache::grades
9470:
9471: =head1 SYNOPSIS
9472:
9473: Handles the viewing of grades.
9474:
9475: This is part of the LearningOnline Network with CAPA project
9476: described at http://www.lon-capa.org.
9477:
9478: =head1 OVERVIEW
9479:
9480: Do an ssi with retries:
9481: While I'd love to factor out this with the vesrion in lonprintout,
9482: 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
9483: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9484:
9485: At least the logic that drives this has been pulled out into loncommon.
9486:
9487:
9488:
9489: ssi_with_retries - Does the server side include of a resource.
9490: if the ssi call returns an error we'll retry it up to
9491: the number of times requested by the caller.
9492: If we still have a proble, no text is appended to the
9493: output and we set some global variables.
9494: to indicate to the caller an SSI error occurred.
9495: All of this is supposed to deal with the issues described
9496: in LonCAPA BZ 5631 see:
9497: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9498: by informing the user that this happened.
9499:
9500: Parameters:
9501: resource - The resource to include. This is passed directly, without
9502: interpretation to lonnet::ssi.
9503: form - The form hash parameters that guide the interpretation of the resource
9504:
9505: retries - Number of retries allowed before giving up completely.
9506: Returns:
9507: On success, returns the rendered resource identified by the resource parameter.
9508: Side Effects:
9509: The following global variables can be set:
9510: ssi_error - If an unrecoverable error occurred this becomes true.
9511: It is up to the caller to initialize this to false
9512: if desired.
9513: ssi_error_resource - If an unrecoverable error occurred, this is the value
9514: of the resource that could not be rendered by the ssi
9515: call.
9516: ssi_error_message - The error string fetched from the ssi response
9517: in the event of an error.

9529:
9530: Builds the interface screen to interact with the operator to fix a
9531: specific error condition in a specific scanline
9532:
9533: Arguments:
9534: $r - Apache request object
9535: $i - number of the current scanline
9536: $scan_record - hash ref as returned from &scantron_parse_scanline()
9537: $scan_config - hash ref as returned from &get_scantron_config()
9538: $line - full contents of the current scanline
9539: $error - error condition, valid values are
9540: 'incorrectCODE', 'duplicateCODE',
9541: 'doublebubble', 'missingbubble',
9542: 'duplicateID', 'incorrectID'
9543: $arg - extra information needed
9544: For errors:
9545: - duplicateID - paper number that this studentID was seen before on
9546: - duplicateCODE - array ref of the paper numbers this CODE was
9547: seen on before
9548: - incorrectCODE - current incorrect CODE
9549: - doublebubble - array ref of the bubble lines that have double
9550: bubble errors
9551: - missingbubble - array ref of the bubble lines that have missing
9552: bubble errors
9553:
9554: =item scantron_get_maxbubble() :
9555:
1.582 raeburn 9556: Arguments:
9557: $nav_error - Reference to scalar which is a flag to indicate a
9558: failure to retrieve a navmap object.
9559: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9560: calling routine should trap the error condition and display the warning
9561: found in &navmap_errormsg().
9562:
1.531 jms 9563: Returns the maximum number of bubble lines that are expected to
9564: occur. Does this by walking the selected sequence rendering the
9565: resource and then checking &Apache::lonxml::get_problem_counter()
9566: for what the current value of the problem counter is.
9567:
9568: Caches the results to $env{'form.scantron_maxbubble'},
9569: $env{'form.scantron.bubble_lines.n'},
9570: $env{'form.scantron.first_bubble_line.n'} and
9571: $env{"form.scantron.sub_bubblelines.n"}
9572: which are the total number of bubble, lines, the number of bubble
9573: lines for response n and number of the first bubble line for response n,
9574: and a comma separated list of numbers of bubble lines for sub-questions
9575: (for optionresponse, matchresponse, and rankresponse items), for response n.

9584: =item scantron_process_students() :
9585:
9586: Routine that does the actual grading of the bubble sheet information.
9587:
9588: The parsed scanline hash is added to %env
9589:
9590: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9591: foreach resource , with the form data of
9592:
9593: 'submitted' =>'scantron'
9594: 'grade_target' =>'grade',
9595: 'grade_username'=> username of student
9596: 'grade_domain' => domain of student
9597: 'grade_courseid'=> of course
9598: 'grade_symb' => symb of resource to grade
9599:
9600: This triggers a grading pass. The problem grading code takes care
9601: of converting the bubbled letter information (now in %env) into a
9602: valid submission.

9621: course.
