4764:
1.424 albertel 4765: For this documentation:
4766:
4767: 'scanline' refers to the full line of characters
4768: from the file that we are parsing that represents one entire sheet
4769:
4770: 'bubble line' refers to the data
4771: representing the line of bubbles that are on the physical bubble sheet
4772:
4773:
4774: The overall process is that a scanned in bubble sheet data is uploaded
4775: into a course. When a user wants to grade, they select a
4776: sequence/folder of resources, a file of bubble sheet info, and pick
4777: one of the predefined configurations for what each scanline looks
4778: like.
4779:
4780: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4781: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4782: because too light bubbling), 'double bubble' (each bubble line should
4783: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4784: invalid student/employee ID
1.424 albertel 4785:
4786: If the CODE option is used that determines the randomization of the
1.556 weissno 4787: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4788: username:domain.
4789:
4790: During the validation phase the instructor can choose to skip scanlines.
4791:
1.435 foxr 4792: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4793:
4794: scantron_original_filename (unmodified original file)
4795: scantron_corrected_filename (file where the corrected information has replaced the original information)
4796: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4797:
4798: Also there is a separate hash nohist_scantrondata that contains extra
4799: correction information that isn't representable in the bubble sheet
4800: file (see &scantron_getfile() for more information)
4801:
4802: After all scanlines are either valid, marked as valid or skipped, then
4803: foreach line foreach problem in the picked sequence, an ssi request is
4804: made that simulates a user submitting their selected letter(s) against
4805: the homework problem.

9366: =head1 NAME
9367:
9368: Apache::grades
9369:
9370: =head1 SYNOPSIS
9371:
9372: Handles the viewing of grades.
9373:
9374: This is part of the LearningOnline Network with CAPA project
9375: described at http://www.lon-capa.org.
9376:
9377: =head1 OVERVIEW
9378:
9379: Do an ssi with retries:
9380: While I'd love to factor out this with the vesrion in lonprintout,
9381: 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
9382: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9383:
9384: At least the logic that drives this has been pulled out into loncommon.
9385:
9386:
9387:
9388: ssi_with_retries - Does the server side include of a resource.
9389: if the ssi call returns an error we'll retry it up to
9390: the number of times requested by the caller.
9391: If we still have a proble, no text is appended to the
9392: output and we set some global variables.
9393: to indicate to the caller an SSI error occurred.
9394: All of this is supposed to deal with the issues described
9395: in LonCAPA BZ 5631 see:
9396: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9397: by informing the user that this happened.
9398:
9399: Parameters:
9400: resource - The resource to include. This is passed directly, without
9401: interpretation to lonnet::ssi.
9402: form - The form hash parameters that guide the interpretation of the resource
9403:
9404: retries - Number of retries allowed before giving up completely.
9405: Returns:
9406: On success, returns the rendered resource identified by the resource parameter.
9407: Side Effects:
9408: The following global variables can be set:
9409: ssi_error - If an unrecoverable error occurred this becomes true.
9410: It is up to the caller to initialize this to false
9411: if desired.
9412: ssi_error_resource - If an unrecoverable error occurred, this is the value
9413: of the resource that could not be rendered by the ssi
9414: call.
9415: ssi_error_message - The error string fetched from the ssi response
9416: in the event of an error.

9426:
9427: =item scantron_get_correction() :
9428:
9429: Builds the interface screen to interact with the operator to fix a
9430: specific error condition in a specific scanline
9431:
9432: Arguments:
9433: $r - Apache request object
9434: $i - number of the current scanline
9435: $scan_record - hash ref as returned from &scantron_parse_scanline()
9436: $scan_config - hash ref as returned from &get_scantron_config()
9437: $line - full contents of the current scanline
9438: $error - error condition, valid values are
9439: 'incorrectCODE', 'duplicateCODE',
9440: 'doublebubble', 'missingbubble',
9441: 'duplicateID', 'incorrectID'
9442: $arg - extra information needed
9443: For errors:
9444: - duplicateID - paper number that this studentID was seen before on
9445: - duplicateCODE - array ref of the paper numbers this CODE was
9446: seen on before
9447: - incorrectCODE - current incorrect CODE
9448: - doublebubble - array ref of the bubble lines that have double
9449: bubble errors
9450: - missingbubble - array ref of the bubble lines that have missing
9451: bubble errors
9452:
9453: =item scantron_get_maxbubble() :
9454:
1.582 raeburn 9455: Arguments:
9456: $nav_error - Reference to scalar which is a flag to indicate a
9457: failure to retrieve a navmap object.
9458: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9459: calling routine should trap the error condition and display the warning
9460: found in &navmap_errormsg().
9461:
1.531 jms 9462: Returns the maximum number of bubble lines that are expected to
9463: occur. Does this by walking the selected sequence rendering the
9464: resource and then checking &Apache::lonxml::get_problem_counter()
9465: for what the current value of the problem counter is.
9466:
9467: Caches the results to $env{'form.scantron_maxbubble'},
9468: $env{'form.scantron.bubble_lines.n'},
9469: $env{'form.scantron.first_bubble_line.n'} and
9470: $env{"form.scantron.sub_bubblelines.n"}
9471: which are the total number of bubble, lines, the number of bubble
9472: lines for response n and number of the first bubble line for response n,
9473: and a comma separated list of numbers of bubble lines for sub-questions
9474: (for optionresponse, matchresponse, and rankresponse items), for response n.
9475:
9476:
9477: =item scantron_validate_missingbubbles() :
9478:
9479: Validates all scanlines in the selected file to not have any
9480: answers that don't have bubbles that have not been verified
9481: to be bubble free.
9482:
9483: =item scantron_process_students() :
9484:
9485: Routine that does the actual grading of the bubble sheet information.
9486:
9487: The parsed scanline hash is added to %env
9488:
9489: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9490: foreach resource , with the form data of
9491:
9492: 'submitted' =>'scantron'
9493: 'grade_target' =>'grade',
9494: 'grade_username'=> username of student
9495: 'grade_domain' => domain of student
9496: 'grade_courseid'=> of course
9497: 'grade_symb' => symb of resource to grade
9498:
9499: This triggers a grading pass. The problem grading code takes care
9500: of converting the bubbled letter information (now in %env) into a
9501: valid submission.
9502:
9503: =item scantron_upload_scantron_data() :
9504:
9505: Creates the screen for adding a new bubble sheet data file to a course.
9506:
9507: =item scantron_upload_scantron_data_save() :
9508:
9509: Adds a provided bubble information data file to the course if user
9510: has the correct privileges to do so.
9511:
9512: =item valid_file() :
9513:
9514: Validates that the requested bubble data file exists in the course.
9515:
9516: =item scantron_download_scantron_data() :
9517:
9518: Shows a list of the three internal files (original, corrected,
9519: skipped) for a specific bubble sheet data file that exists in the
9520: course.
9521:
9522: =item scantron_validate_ID() :
9523:
9524: Validates all scanlines in the selected file to not have any
1.556 weissno 9525: invalid or underspecified student/employee IDs
1.531 jms 9526:
1.582 raeburn 9527: =item navmap_errormsg() :
9528:
9529: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9530: Should be called whenever the request to instantiate a navmap object fails.
