4780:
1.424 albertel 4781: For this documentation:
4782:
4783: 'scanline' refers to the full line of characters
4784: from the file that we are parsing that represents one entire sheet
4785:
4786: 'bubble line' refers to the data
4787: representing the line of bubbles that are on the physical bubble sheet
4788:
4789:
4790: The overall process is that a scanned in bubble sheet data is uploaded
4791: into a course. When a user wants to grade, they select a
4792: sequence/folder of resources, a file of bubble sheet info, and pick
4793: one of the predefined configurations for what each scanline looks
4794: like.
4795:
4796: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4797: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4798: because too light bubbling), 'double bubble' (each bubble line should
4799: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4800: invalid student/employee ID
1.424 albertel 4801:
4802: If the CODE option is used that determines the randomization of the
1.556 weissno 4803: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4804: username:domain.
4805:
4806: During the validation phase the instructor can choose to skip scanlines.
4807:
1.435 foxr 4808: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4809:
4810: scantron_original_filename (unmodified original file)
4811: scantron_corrected_filename (file where the corrected information has replaced the original information)
4812: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4813:
4814: Also there is a separate hash nohist_scantrondata that contains extra
4815: correction information that isn't representable in the bubble sheet
4816: file (see &scantron_getfile() for more information)
4817:
4818: After all scanlines are either valid, marked as valid or skipped, then
4819: foreach line foreach problem in the picked sequence, an ssi request is
4820: made that simulates a user submitting their selected letter(s) against
4821: the homework problem.

9408: =head1 NAME
9409:
9410: Apache::grades
9411:
9412: =head1 SYNOPSIS
9413:
9414: Handles the viewing of grades.
9415:
9416: This is part of the LearningOnline Network with CAPA project
9417: described at http://www.lon-capa.org.
9418:
9419: =head1 OVERVIEW
9420:
9421: Do an ssi with retries:
9422: While I'd love to factor out this with the vesrion in lonprintout,
9423: 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
9424: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9425:
9426: At least the logic that drives this has been pulled out into loncommon.
9427:
9428:
9429:
9430: ssi_with_retries - Does the server side include of a resource.
9431: if the ssi call returns an error we'll retry it up to
9432: the number of times requested by the caller.
9433: If we still have a proble, no text is appended to the
9434: output and we set some global variables.
9435: to indicate to the caller an SSI error occurred.
9436: All of this is supposed to deal with the issues described
9437: in LonCAPA BZ 5631 see:
9438: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9439: by informing the user that this happened.
9440:
9441: Parameters:
9442: resource - The resource to include. This is passed directly, without
9443: interpretation to lonnet::ssi.
9444: form - The form hash parameters that guide the interpretation of the resource
9445:
9446: retries - Number of retries allowed before giving up completely.
9447: Returns:
9448: On success, returns the rendered resource identified by the resource parameter.
9449: Side Effects:
9450: The following global variables can be set:
9451: ssi_error - If an unrecoverable error occurred this becomes true.
9452: It is up to the caller to initialize this to false
9453: if desired.
9454: ssi_error_resource - If an unrecoverable error occurred, this is the value
9455: of the resource that could not be rendered by the ssi
9456: call.
9457: ssi_error_message - The error string fetched from the ssi response
9458: in the event of an error.

9470:
9471: Builds the interface screen to interact with the operator to fix a
9472: specific error condition in a specific scanline
9473:
9474: Arguments:
9475: $r - Apache request object
9476: $i - number of the current scanline
9477: $scan_record - hash ref as returned from &scantron_parse_scanline()
9478: $scan_config - hash ref as returned from &get_scantron_config()
9479: $line - full contents of the current scanline
9480: $error - error condition, valid values are
9481: 'incorrectCODE', 'duplicateCODE',
9482: 'doublebubble', 'missingbubble',
9483: 'duplicateID', 'incorrectID'
9484: $arg - extra information needed
9485: For errors:
9486: - duplicateID - paper number that this studentID was seen before on
9487: - duplicateCODE - array ref of the paper numbers this CODE was
9488: seen on before
9489: - incorrectCODE - current incorrect CODE
9490: - doublebubble - array ref of the bubble lines that have double
9491: bubble errors
9492: - missingbubble - array ref of the bubble lines that have missing
9493: bubble errors
9494:
9495: =item scantron_get_maxbubble() :
9496:
1.574.2.7 raeburn 9497: Arguments:
9498: $nav_error - Reference to scalar which is a flag to indicate a
9499: failure to retrieve a navmap object.
9500: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9501: calling routine should trap the error condition and display the warning
9502: found in &navmap_errormsg().
9503:
1.531 jms 9504: Returns the maximum number of bubble lines that are expected to
9505: occur. Does this by walking the selected sequence rendering the
9506: resource and then checking &Apache::lonxml::get_problem_counter()
9507: for what the current value of the problem counter is.
9508:
9509: Caches the results to $env{'form.scantron_maxbubble'},
9510: $env{'form.scantron.bubble_lines.n'},
9511: $env{'form.scantron.first_bubble_line.n'} and
9512: $env{"form.scantron.sub_bubblelines.n"}
9513: which are the total number of bubble, lines, the number of bubble
9514: lines for response n and number of the first bubble line for response n,
9515: and a comma separated list of numbers of bubble lines for sub-questions
9516: (for optionresponse, matchresponse, and rankresponse items), for response n.

9524:
9525: =item scantron_process_students() :
9526:
9527: Routine that does the actual grading of the bubble sheet information.
9528:
9529: The parsed scanline hash is added to %env
9530:
9531: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9532: foreach resource , with the form data of
9533:
9534: 'submitted' =>'scantron'
9535: 'grade_target' =>'grade',
9536: 'grade_username'=> username of student
9537: 'grade_domain' => domain of student
9538: 'grade_courseid'=> of course
9539: 'grade_symb' => symb of resource to grade
9540:
9541: This triggers a grading pass. The problem grading code takes care
9542: of converting the bubbled letter information (now in %env) into a
9543: valid submission.

9562: course.
9563:
9564: =item scantron_validate_ID() :
