4757:
1.424 albertel 4758: For this documentation:
4759:
4760: 'scanline' refers to the full line of characters
4761: from the file that we are parsing that represents one entire sheet
4762:
4763: 'bubble line' refers to the data
4764: representing the line of bubbles that are on the physical bubble sheet
4765:
4766:
4767: The overall process is that a scanned in bubble sheet data is uploaded
4768: into a course. When a user wants to grade, they select a
4769: sequence/folder of resources, a file of bubble sheet info, and pick
4770: one of the predefined configurations for what each scanline looks
4771: like.
4772:
4773: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4774: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4775: because too light bubbling), 'double bubble' (each bubble line should
4776: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4777: invalid student/employee ID
1.424 albertel 4778:
4779: If the CODE option is used that determines the randomization of the
1.556 weissno 4780: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4781: username:domain.
4782:
4783: During the validation phase the instructor can choose to skip scanlines.
4784:
1.435 foxr 4785: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4786:
4787: scantron_original_filename (unmodified original file)
4788: scantron_corrected_filename (file where the corrected information has replaced the original information)
4789: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4790:
4791: Also there is a separate hash nohist_scantrondata that contains extra
4792: correction information that isn't representable in the bubble sheet
4793: file (see &scantron_getfile() for more information)
4794:
4795: After all scanlines are either valid, marked as valid or skipped, then
4796: foreach line foreach problem in the picked sequence, an ssi request is
4797: made that simulates a user submitting their selected letter(s) against
4798: the homework problem.

9359: =head1 NAME
9360:
9361: Apache::grades
9362:
9363: =head1 SYNOPSIS
9364:
9365: Handles the viewing of grades.
9366:
9367: This is part of the LearningOnline Network with CAPA project
9368: described at http://www.lon-capa.org.
9369:
9370: =head1 OVERVIEW
9371:
9372: Do an ssi with retries:
9373: While I'd love to factor out this with the vesrion in lonprintout,
9374: 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
9375: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9376:
9377: At least the logic that drives this has been pulled out into loncommon.
9378:
9379:
9380:
9381: ssi_with_retries - Does the server side include of a resource.
9382: if the ssi call returns an error we'll retry it up to
9383: the number of times requested by the caller.
9384: If we still have a proble, no text is appended to the
9385: output and we set some global variables.
9386: to indicate to the caller an SSI error occurred.
9387: All of this is supposed to deal with the issues described
9388: in LonCAPA BZ 5631 see:
9389: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9390: by informing the user that this happened.
9391:
9392: Parameters:
9393: resource - The resource to include. This is passed directly, without
9394: interpretation to lonnet::ssi.
9395: form - The form hash parameters that guide the interpretation of the resource
9396:
9397: retries - Number of retries allowed before giving up completely.
9398: Returns:
9399: On success, returns the rendered resource identified by the resource parameter.
9400: Side Effects:
9401: The following global variables can be set:
9402: ssi_error - If an unrecoverable error occurred this becomes true.
9403: It is up to the caller to initialize this to false
9404: if desired.
9405: ssi_error_resource - If an unrecoverable error occurred, this is the value
9406: of the resource that could not be rendered by the ssi
9407: call.
9408: ssi_error_message - The error string fetched from the ssi response
9409: in the event of an error.

9419:
9420: =item scantron_get_correction() :
9421:
9422: Builds the interface screen to interact with the operator to fix a
9423: specific error condition in a specific scanline
9424:
9425: Arguments:
9426: $r - Apache request object
9427: $i - number of the current scanline
9428: $scan_record - hash ref as returned from &scantron_parse_scanline()
9429: $scan_config - hash ref as returned from &get_scantron_config()
9430: $line - full contents of the current scanline
9431: $error - error condition, valid values are
9432: 'incorrectCODE', 'duplicateCODE',
9433: 'doublebubble', 'missingbubble',
9434: 'duplicateID', 'incorrectID'
9435: $arg - extra information needed
9436: For errors:
9437: - duplicateID - paper number that this studentID was seen before on
9438: - duplicateCODE - array ref of the paper numbers this CODE was
9439: seen on before
9440: - incorrectCODE - current incorrect CODE
9441: - doublebubble - array ref of the bubble lines that have double
9442: bubble errors
9443: - missingbubble - array ref of the bubble lines that have missing
9444: bubble errors
9445:
9446: =item scantron_get_maxbubble() :
9447:
1.582 raeburn 9448: Arguments:
9449: $nav_error - Reference to scalar which is a flag to indicate a
9450: failure to retrieve a navmap object.
9451: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9452: calling routine should trap the error condition and display the warning
9453: found in &navmap_errormsg().
9454:
1.531 jms 9455: Returns the maximum number of bubble lines that are expected to
9456: occur. Does this by walking the selected sequence rendering the
9457: resource and then checking &Apache::lonxml::get_problem_counter()
9458: for what the current value of the problem counter is.
9459:
9460: Caches the results to $env{'form.scantron_maxbubble'},
9461: $env{'form.scantron.bubble_lines.n'},
9462: $env{'form.scantron.first_bubble_line.n'} and
9463: $env{"form.scantron.sub_bubblelines.n"}
9464: which are the total number of bubble, lines, the number of bubble
9465: lines for response n and number of the first bubble line for response n,
9466: and a comma separated list of numbers of bubble lines for sub-questions
9467: (for optionresponse, matchresponse, and rankresponse items), for response n.
9468:
9469:
9470: =item scantron_validate_missingbubbles() :
9471:
9472: Validates all scanlines in the selected file to not have any
9473: answers that don't have bubbles that have not been verified
9474: to be bubble free.
9475:
9476: =item scantron_process_students() :
9477:
9478: Routine that does the actual grading of the bubble sheet information.
9479:
9480: The parsed scanline hash is added to %env
9481:
9482: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9483: foreach resource , with the form data of
9484:
9485: 'submitted' =>'scantron'
9486: 'grade_target' =>'grade',
9487: 'grade_username'=> username of student
9488: 'grade_domain' => domain of student
9489: 'grade_courseid'=> of course
9490: 'grade_symb' => symb of resource to grade
9491:
9492: This triggers a grading pass. The problem grading code takes care
9493: of converting the bubbled letter information (now in %env) into a
9494: valid submission.
9495:
9496: =item scantron_upload_scantron_data() :
9497:
9498: Creates the screen for adding a new bubble sheet data file to a course.
9499:
9500: =item scantron_upload_scantron_data_save() :
9501:
9502: Adds a provided bubble information data file to the course if user
9503: has the correct privileges to do so.
9504:
9505: =item valid_file() :
9506:
9507: Validates that the requested bubble data file exists in the course.
9508:
9509: =item scantron_download_scantron_data() :
9510:
9511: Shows a list of the three internal files (original, corrected,
9512: skipped) for a specific bubble sheet data file that exists in the
9513: course.
9514:
9515: =item scantron_validate_ID() :
9516:
9517: Validates all scanlines in the selected file to not have any
1.556 weissno 9518: invalid or underspecified student/employee IDs
1.531 jms 9519:
1.582 raeburn 9520: =item navmap_errormsg() :
9521:
9522: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9523: Should be called whenever the request to instantiate a navmap object fails.
