4736:
1.424 albertel 4737: For this documentation:
4738:
4739: 'scanline' refers to the full line of characters
4740: from the file that we are parsing that represents one entire sheet
4741:
4742: 'bubble line' refers to the data
4743: representing the line of bubbles that are on the physical bubble sheet
4744:
4745:
4746: The overall process is that a scanned in bubble sheet data is uploaded
4747: into a course. When a user wants to grade, they select a
4748: sequence/folder of resources, a file of bubble sheet info, and pick
4749: one of the predefined configurations for what each scanline looks
4750: like.
4751:
4752: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4753: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4754: because too light bubbling), 'double bubble' (each bubble line should
4755: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4756: invalid student/employee ID
1.424 albertel 4757:
4758: If the CODE option is used that determines the randomization of the
1.556 weissno 4759: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4760: username:domain.
4761:
4762: During the validation phase the instructor can choose to skip scanlines.
4763:
1.435 foxr 4764: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4765:
4766: scantron_original_filename (unmodified original file)
4767: scantron_corrected_filename (file where the corrected information has replaced the original information)
4768: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4769:
4770: Also there is a separate hash nohist_scantrondata that contains extra
4771: correction information that isn't representable in the bubble sheet
4772: file (see &scantron_getfile() for more information)
4773:
4774: After all scanlines are either valid, marked as valid or skipped, then
4775: foreach line foreach problem in the picked sequence, an ssi request is
4776: made that simulates a user submitting their selected letter(s) against
4777: the homework problem.

9348: =head1 NAME
9349:
9350: Apache::grades
9351:
9352: =head1 SYNOPSIS
9353:
9354: Handles the viewing of grades.
9355:
9356: This is part of the LearningOnline Network with CAPA project
9357: described at http://www.lon-capa.org.
9358:
9359: =head1 OVERVIEW
9360:
9361: Do an ssi with retries:
9362: While I'd love to factor out this with the vesrion in lonprintout,
9363: 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
9364: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9365:
9366: At least the logic that drives this has been pulled out into loncommon.
9367:
9368:
9369:
9370: ssi_with_retries - Does the server side include of a resource.
9371: if the ssi call returns an error we'll retry it up to
9372: the number of times requested by the caller.
9373: If we still have a proble, no text is appended to the
9374: output and we set some global variables.
9375: to indicate to the caller an SSI error occurred.
9376: All of this is supposed to deal with the issues described
9377: in LonCAPA BZ 5631 see:
9378: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9379: by informing the user that this happened.
9380:
9381: Parameters:
9382: resource - The resource to include. This is passed directly, without
9383: interpretation to lonnet::ssi.
9384: form - The form hash parameters that guide the interpretation of the resource
9385:
9386: retries - Number of retries allowed before giving up completely.
9387: Returns:
9388: On success, returns the rendered resource identified by the resource parameter.
9389: Side Effects:
9390: The following global variables can be set:
9391: ssi_error - If an unrecoverable error occurred this becomes true.
9392: It is up to the caller to initialize this to false
9393: if desired.
9394: ssi_error_resource - If an unrecoverable error occurred, this is the value
9395: of the resource that could not be rendered by the ssi
9396: call.
9397: ssi_error_message - The error string fetched from the ssi response
9398: in the event of an error.

9408:
9409: =item scantron_get_correction() :
9410:
9411: Builds the interface screen to interact with the operator to fix a
9412: specific error condition in a specific scanline
9413:
9414: Arguments:
9415: $r - Apache request object
9416: $i - number of the current scanline
9417: $scan_record - hash ref as returned from &scantron_parse_scanline()
9418: $scan_config - hash ref as returned from &get_scantron_config()
9419: $line - full contents of the current scanline
9420: $error - error condition, valid values are
9421: 'incorrectCODE', 'duplicateCODE',
9422: 'doublebubble', 'missingbubble',
9423: 'duplicateID', 'incorrectID'
9424: $arg - extra information needed
9425: For errors:
9426: - duplicateID - paper number that this studentID was seen before on
9427: - duplicateCODE - array ref of the paper numbers this CODE was
9428: seen on before
9429: - incorrectCODE - current incorrect CODE
9430: - doublebubble - array ref of the bubble lines that have double
9431: bubble errors
9432: - missingbubble - array ref of the bubble lines that have missing
9433: bubble errors
9434:
9435: =item scantron_get_maxbubble() :
9436:
1.582 raeburn 9437: Arguments:
9438: $nav_error - Reference to scalar which is a flag to indicate a
9439: failure to retrieve a navmap object.
9440: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9441: calling routine should trap the error condition and display the warning
9442: found in &navmap_errormsg().
9443:
1.531 jms 9444: Returns the maximum number of bubble lines that are expected to
9445: occur. Does this by walking the selected sequence rendering the
9446: resource and then checking &Apache::lonxml::get_problem_counter()
9447: for what the current value of the problem counter is.
9448:
9449: Caches the results to $env{'form.scantron_maxbubble'},
9450: $env{'form.scantron.bubble_lines.n'},
9451: $env{'form.scantron.first_bubble_line.n'} and
9452: $env{"form.scantron.sub_bubblelines.n"}
9453: which are the total number of bubble, lines, the number of bubble
9454: lines for response n and number of the first bubble line for response n,
9455: and a comma separated list of numbers of bubble lines for sub-questions
9456: (for optionresponse, matchresponse, and rankresponse items), for response n.
9457:
9458:
9459: =item scantron_validate_missingbubbles() :
9460:
9461: Validates all scanlines in the selected file to not have any
9462: answers that don't have bubbles that have not been verified
9463: to be bubble free.
9464:
9465: =item scantron_process_students() :
9466:
9467: Routine that does the actual grading of the bubble sheet information.
9468:
9469: The parsed scanline hash is added to %env
9470:
9471: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9472: foreach resource , with the form data of
9473:
9474: 'submitted' =>'scantron'
9475: 'grade_target' =>'grade',
9476: 'grade_username'=> username of student
9477: 'grade_domain' => domain of student
9478: 'grade_courseid'=> of course
9479: 'grade_symb' => symb of resource to grade
9480:
9481: This triggers a grading pass. The problem grading code takes care
9482: of converting the bubbled letter information (now in %env) into a
9483: valid submission.
9484:
9485: =item scantron_upload_scantron_data() :
9486:
9487: Creates the screen for adding a new bubble sheet data file to a course.
9488:
9489: =item scantron_upload_scantron_data_save() :
9490:
9491: Adds a provided bubble information data file to the course if user
9492: has the correct privileges to do so.
9493:
9494: =item valid_file() :
9495:
9496: Validates that the requested bubble data file exists in the course.
9497:
9498: =item scantron_download_scantron_data() :
9499:
9500: Shows a list of the three internal files (original, corrected,
9501: skipped) for a specific bubble sheet data file that exists in the
9502: course.
9503:
9504: =item scantron_validate_ID() :
9505:
9506: Validates all scanlines in the selected file to not have any
1.556 weissno 9507: invalid or underspecified student/employee IDs
1.531 jms 9508:
1.582 raeburn 9509: =item navmap_errormsg() :
9510:
9511: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9512: Should be called whenever the request to instantiate a navmap object fails.
