4870:
1.424 albertel 4871: For this documentation:
4872:
4873: 'scanline' refers to the full line of characters
4874: from the file that we are parsing that represents one entire sheet
4875:
4876: 'bubble line' refers to the data
4877: representing the line of bubbles that are on the physical bubble sheet
4878:
4879:
4880: The overall process is that a scanned in bubble sheet data is uploaded
4881: into a course. When a user wants to grade, they select a
4882: sequence/folder of resources, a file of bubble sheet info, and pick
4883: one of the predefined configurations for what each scanline looks
4884: like.
4885:
4886: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4887: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4888: because too light bubbling), 'double bubble' (each bubble line should
4889: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4890: invalid student/employee ID
1.424 albertel 4891:
4892: If the CODE option is used that determines the randomization of the
1.556 weissno 4893: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4894: username:domain.
4895:
4896: During the validation phase the instructor can choose to skip scanlines.
4897:
1.435 foxr 4898: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4899:
4900: scantron_original_filename (unmodified original file)
4901: scantron_corrected_filename (file where the corrected information has replaced the original information)
4902: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4903:
4904: Also there is a separate hash nohist_scantrondata that contains extra
4905: correction information that isn't representable in the bubble sheet
4906: file (see &scantron_getfile() for more information)
4907:
4908: After all scanlines are either valid, marked as valid or skipped, then
4909: foreach line foreach problem in the picked sequence, an ssi request is
4910: made that simulates a user submitting their selected letter(s) against
4911: the homework problem.

9480: =head1 NAME
9481:
9482: Apache::grades
9483:
9484: =head1 SYNOPSIS
9485:
9486: Handles the viewing of grades.
9487:
9488: This is part of the LearningOnline Network with CAPA project
9489: described at http://www.lon-capa.org.
9490:
9491: =head1 OVERVIEW
9492:
9493: Do an ssi with retries:
9494: While I'd love to factor out this with the vesrion in lonprintout,
9495: 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
9496: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9497:
9498: At least the logic that drives this has been pulled out into loncommon.
9499:
9500:
9501:
9502: ssi_with_retries - Does the server side include of a resource.
9503: if the ssi call returns an error we'll retry it up to
9504: the number of times requested by the caller.
9505: If we still have a proble, no text is appended to the
9506: output and we set some global variables.
9507: to indicate to the caller an SSI error occurred.
9508: All of this is supposed to deal with the issues described
9509: in LonCAPA BZ 5631 see:
9510: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9511: by informing the user that this happened.
9512:
9513: Parameters:
9514: resource - The resource to include. This is passed directly, without
9515: interpretation to lonnet::ssi.
9516: form - The form hash parameters that guide the interpretation of the resource
9517:
9518: retries - Number of retries allowed before giving up completely.
9519: Returns:
9520: On success, returns the rendered resource identified by the resource parameter.
9521: Side Effects:
9522: The following global variables can be set:
9523: ssi_error - If an unrecoverable error occurred this becomes true.
9524: It is up to the caller to initialize this to false
9525: if desired.
9526: ssi_error_resource - If an unrecoverable error occurred, this is the value
9527: of the resource that could not be rendered by the ssi
9528: call.
9529: ssi_error_message - The error string fetched from the ssi response
9530: in the event of an error.

9542:
9543: Builds the interface screen to interact with the operator to fix a
9544: specific error condition in a specific scanline
9545:
9546: Arguments:
9547: $r - Apache request object
9548: $i - number of the current scanline
9549: $scan_record - hash ref as returned from &scantron_parse_scanline()
9550: $scan_config - hash ref as returned from &get_scantron_config()
9551: $line - full contents of the current scanline
9552: $error - error condition, valid values are
9553: 'incorrectCODE', 'duplicateCODE',
9554: 'doublebubble', 'missingbubble',
9555: 'duplicateID', 'incorrectID'
9556: $arg - extra information needed
9557: For errors:
9558: - duplicateID - paper number that this studentID was seen before on
9559: - duplicateCODE - array ref of the paper numbers this CODE was
9560: seen on before
9561: - incorrectCODE - current incorrect CODE
9562: - doublebubble - array ref of the bubble lines that have double
9563: bubble errors
9564: - missingbubble - array ref of the bubble lines that have missing
9565: bubble errors
9566:
9567: =item scantron_get_maxbubble() :
9568:
1.582 raeburn 9569: Arguments:
9570: $nav_error - Reference to scalar which is a flag to indicate a
9571: failure to retrieve a navmap object.
9572: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9573: calling routine should trap the error condition and display the warning
9574: found in &navmap_errormsg().
9575:
1.531 jms 9576: Returns the maximum number of bubble lines that are expected to
9577: occur. Does this by walking the selected sequence rendering the
9578: resource and then checking &Apache::lonxml::get_problem_counter()
9579: for what the current value of the problem counter is.
9580:
9581: Caches the results to $env{'form.scantron_maxbubble'},
9582: $env{'form.scantron.bubble_lines.n'},
9583: $env{'form.scantron.first_bubble_line.n'} and
9584: $env{"form.scantron.sub_bubblelines.n"}
9585: which are the total number of bubble, lines, the number of bubble
9586: lines for response n and number of the first bubble line for response n,
9587: and a comma separated list of numbers of bubble lines for sub-questions
9588: (for optionresponse, matchresponse, and rankresponse items), for response n.

9597: =item scantron_process_students() :
9598:
9599: Routine that does the actual grading of the bubble sheet information.
9600:
9601: The parsed scanline hash is added to %env
9602:
9603: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9604: foreach resource , with the form data of
9605:
9606: 'submitted' =>'scantron'
9607: 'grade_target' =>'grade',
9608: 'grade_username'=> username of student
9609: 'grade_domain' => domain of student
9610: 'grade_courseid'=> of course
9611: 'grade_symb' => symb of resource to grade
9612:
9613: This triggers a grading pass. The problem grading code takes care
9614: of converting the bubbled letter information (now in %env) into a
9615: valid submission.

9634: course.
9635:
9636: =item scantron_validate_ID() :
