4797:
1.424 albertel 4798: For this documentation:
4799:
4800: 'scanline' refers to the full line of characters
4801: from the file that we are parsing that represents one entire sheet
4802:
4803: 'bubble line' refers to the data
4804: representing the line of bubbles that are on the physical bubble sheet
4805:
4806:
4807: The overall process is that a scanned in bubble sheet data is uploaded
4808: into a course. When a user wants to grade, they select a
4809: sequence/folder of resources, a file of bubble sheet info, and pick
4810: one of the predefined configurations for what each scanline looks
4811: like.
4812:
4813: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4814: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4815: because too light bubbling), 'double bubble' (each bubble line should
4816: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4817: invalid student/employee ID
1.424 albertel 4818:
4819: If the CODE option is used that determines the randomization of the
1.556 weissno 4820: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4821: username:domain.
4822:
4823: During the validation phase the instructor can choose to skip scanlines.
4824:
1.435 foxr 4825: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4826:
4827: scantron_original_filename (unmodified original file)
4828: scantron_corrected_filename (file where the corrected information has replaced the original information)
4829: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4830:
4831: Also there is a separate hash nohist_scantrondata that contains extra
4832: correction information that isn't representable in the bubble sheet
4833: file (see &scantron_getfile() for more information)
4834:
4835: After all scanlines are either valid, marked as valid or skipped, then
4836: foreach line foreach problem in the picked sequence, an ssi request is
4837: made that simulates a user submitting their selected letter(s) against
4838: the homework problem.

9354: =head1 NAME
9355:
9356: Apache::grades
9357:
9358: =head1 SYNOPSIS
9359:
9360: Handles the viewing of grades.
9361:
9362: This is part of the LearningOnline Network with CAPA project
9363: described at http://www.lon-capa.org.
9364:
9365: =head1 OVERVIEW
9366:
9367: Do an ssi with retries:
9368: While I'd love to factor out this with the vesrion in lonprintout,
9369: 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
9370: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9371:
9372: At least the logic that drives this has been pulled out into loncommon.
9373:
9374:
9375:
9376: ssi_with_retries - Does the server side include of a resource.
9377: if the ssi call returns an error we'll retry it up to
9378: the number of times requested by the caller.
9379: If we still have a proble, no text is appended to the
9380: output and we set some global variables.
9381: to indicate to the caller an SSI error occurred.
9382: All of this is supposed to deal with the issues described
9383: in LonCAPA BZ 5631 see:
9384: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9385: by informing the user that this happened.
9386:
9387: Parameters:
9388: resource - The resource to include. This is passed directly, without
9389: interpretation to lonnet::ssi.
9390: form - The form hash parameters that guide the interpretation of the resource
9391:
9392: retries - Number of retries allowed before giving up completely.
9393: Returns:
9394: On success, returns the rendered resource identified by the resource parameter.
9395: Side Effects:
9396: The following global variables can be set:
9397: ssi_error - If an unrecoverable error occurred this becomes true.
9398: It is up to the caller to initialize this to false
9399: if desired.
9400: ssi_error_resource - If an unrecoverable error occurred, this is the value
9401: of the resource that could not be rendered by the ssi
9402: call.
9403: ssi_error_message - The error string fetched from the ssi response
9404: in the event of an error.

9414:
9415: =item scantron_get_correction() :
9416:
9417: Builds the interface screen to interact with the operator to fix a
9418: specific error condition in a specific scanline
9419:
9420: Arguments:
9421: $r - Apache request object
9422: $i - number of the current scanline
9423: $scan_record - hash ref as returned from &scantron_parse_scanline()
9424: $scan_config - hash ref as returned from &get_scantron_config()
9425: $line - full contents of the current scanline
9426: $error - error condition, valid values are
9427: 'incorrectCODE', 'duplicateCODE',
9428: 'doublebubble', 'missingbubble',
9429: 'duplicateID', 'incorrectID'
9430: $arg - extra information needed
9431: For errors:
9432: - duplicateID - paper number that this studentID was seen before on
9433: - duplicateCODE - array ref of the paper numbers this CODE was
9434: seen on before
9435: - incorrectCODE - current incorrect CODE
9436: - doublebubble - array ref of the bubble lines that have double
9437: bubble errors
9438: - missingbubble - array ref of the bubble lines that have missing
9439: bubble errors
9440:
9441: =item scantron_get_maxbubble() :
9442:
1.582 raeburn 9443: Arguments:
9444: $nav_error - Reference to scalar which is a flag to indicate a
9445: failure to retrieve a navmap object.
9446: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9447: calling routine should trap the error condition and display the warning
9448: found in &navmap_errormsg().
9449:
1.531 jms 9450: Returns the maximum number of bubble lines that are expected to
9451: occur. Does this by walking the selected sequence rendering the
9452: resource and then checking &Apache::lonxml::get_problem_counter()
9453: for what the current value of the problem counter is.
9454:
9455: Caches the results to $env{'form.scantron_maxbubble'},
9456: $env{'form.scantron.bubble_lines.n'},
9457: $env{'form.scantron.first_bubble_line.n'} and
9458: $env{"form.scantron.sub_bubblelines.n"}
9459: which are the total number of bubble, lines, the number of bubble
9460: lines for response n and number of the first bubble line for response n,
9461: and a comma separated list of numbers of bubble lines for sub-questions
9462: (for optionresponse, matchresponse, and rankresponse items), for response n.
9463:
9464:
9465: =item scantron_validate_missingbubbles() :
9466:
9467: Validates all scanlines in the selected file to not have any
9468: answers that don't have bubbles that have not been verified
9469: to be bubble free.
9470:
9471: =item scantron_process_students() :
9472:
9473: Routine that does the actual grading of the bubble sheet information.
9474:
9475: The parsed scanline hash is added to %env
9476:
9477: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9478: foreach resource , with the form data of
9479:
9480: 'submitted' =>'scantron'
9481: 'grade_target' =>'grade',
9482: 'grade_username'=> username of student
9483: 'grade_domain' => domain of student
9484: 'grade_courseid'=> of course
9485: 'grade_symb' => symb of resource to grade
9486:
9487: This triggers a grading pass. The problem grading code takes care
9488: of converting the bubbled letter information (now in %env) into a
9489: valid submission.
9490:
9491: =item scantron_upload_scantron_data() :
9492:
9493: Creates the screen for adding a new bubble sheet data file to a course.
9494:
9495: =item scantron_upload_scantron_data_save() :
9496:
9497: Adds a provided bubble information data file to the course if user
9498: has the correct privileges to do so.
9499:
9500: =item valid_file() :
9501:
9502: Validates that the requested bubble data file exists in the course.
9503:
9504: =item scantron_download_scantron_data() :
9505:
9506: Shows a list of the three internal files (original, corrected,
9507: skipped) for a specific bubble sheet data file that exists in the
9508: course.
9509:
9510: =item scantron_validate_ID() :
9511:
9512: Validates all scanlines in the selected file to not have any
1.556 weissno 9513: invalid or underspecified student/employee IDs
1.531 jms 9514:
1.582 raeburn 9515: =item navmap_errormsg() :
9516:
9517: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9518: Should be called whenever the request to instantiate a navmap object fails.
