1.424 albertel 4844: For this documentation:
4845:
4846: 'scanline' refers to the full line of characters
4847: from the file that we are parsing that represents one entire sheet
4848:
4849: 'bubble line' refers to the data
4850: representing the line of bubbles that are on the physical bubble sheet
4851:
4852:
4853: The overall process is that a scanned in bubble sheet data is uploaded
4854: into a course. When a user wants to grade, they select a
4855: sequence/folder of resources, a file of bubble sheet info, and pick
4856: one of the predefined configurations for what each scanline looks
4857: like.
4858:
4859: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4860: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4861: because too light bubbling), 'double bubble' (each bubble line should
4862: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4863: invalid student/employee ID
1.424 albertel 4864:
4865: If the CODE option is used that determines the randomization of the
1.556 weissno 4866: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4867: username:domain.
4868:
4869: During the validation phase the instructor can choose to skip scanlines.
4870:
1.435 foxr 4871: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4872:
4873: scantron_original_filename (unmodified original file)
4874: scantron_corrected_filename (file where the corrected information has replaced the original information)
4875: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4876:
4877: Also there is a separate hash nohist_scantrondata that contains extra
4878: correction information that isn't representable in the bubble sheet
4879: file (see &scantron_getfile() for more information)
4880:
4881: After all scanlines are either valid, marked as valid or skipped, then
4882: foreach line foreach problem in the picked sequence, an ssi request is
4883: made that simulates a user submitting their selected letter(s) against
4884: the homework problem.

9389: =head1 NAME
9390:
9391: Apache::grades
9392:
9393: =head1 SYNOPSIS
9394:
9395: Handles the viewing of grades.
9396:
9397: This is part of the LearningOnline Network with CAPA project
9398: described at http://www.lon-capa.org.
9399:
9400: =head1 OVERVIEW
9401:
9402: Do an ssi with retries:
9403: While I'd love to factor out this with the vesrion in lonprintout,
9404: 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
9405: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9406:
9407: At least the logic that drives this has been pulled out into loncommon.
9408:
9409:
9410:
9411: ssi_with_retries - Does the server side include of a resource.
9412: if the ssi call returns an error we'll retry it up to
9413: the number of times requested by the caller.
9414: If we still have a proble, no text is appended to the
9415: output and we set some global variables.
9416: to indicate to the caller an SSI error occurred.
9417: All of this is supposed to deal with the issues described
9418: in LonCAPA BZ 5631 see:
9419: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9420: by informing the user that this happened.
9421:
9422: Parameters:
9423: resource - The resource to include. This is passed directly, without
9424: interpretation to lonnet::ssi.
9425: form - The form hash parameters that guide the interpretation of the resource
9426:
9427: retries - Number of retries allowed before giving up completely.
9428: Returns:
9429: On success, returns the rendered resource identified by the resource parameter.
9430: Side Effects:
9431: The following global variables can be set:
9432: ssi_error - If an unrecoverable error occurred this becomes true.
9433: It is up to the caller to initialize this to false
9434: if desired.
9435: ssi_error_resource - If an unrecoverable error occurred, this is the value
9436: of the resource that could not be rendered by the ssi
9437: call.
9438: ssi_error_message - The error string fetched from the ssi response
9439: in the event of an error.

9449:
9450: =item scantron_get_correction() :
9451:
9452: Builds the interface screen to interact with the operator to fix a
9453: specific error condition in a specific scanline
9454:
9455: Arguments:
9456: $r - Apache request object
9457: $i - number of the current scanline
9458: $scan_record - hash ref as returned from &scantron_parse_scanline()
9459: $scan_config - hash ref as returned from &get_scantron_config()
9460: $line - full contents of the current scanline
9461: $error - error condition, valid values are
9462: 'incorrectCODE', 'duplicateCODE',
9463: 'doublebubble', 'missingbubble',
9464: 'duplicateID', 'incorrectID'
9465: $arg - extra information needed
9466: For errors:
9467: - duplicateID - paper number that this studentID was seen before on
9468: - duplicateCODE - array ref of the paper numbers this CODE was
9469: seen on before
9470: - incorrectCODE - current incorrect CODE
9471: - doublebubble - array ref of the bubble lines that have double
9472: bubble errors
9473: - missingbubble - array ref of the bubble lines that have missing
9474: bubble errors
9475:
9476: =item scantron_get_maxbubble() :
9477:
1.582 raeburn 9478: Arguments:
9479: $nav_error - Reference to scalar which is a flag to indicate a
9480: failure to retrieve a navmap object.
9481: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9482: calling routine should trap the error condition and display the warning
9483: found in &navmap_errormsg().
9484:
1.531 jms 9485: Returns the maximum number of bubble lines that are expected to
9486: occur. Does this by walking the selected sequence rendering the
9487: resource and then checking &Apache::lonxml::get_problem_counter()
9488: for what the current value of the problem counter is.
9489:
9490: Caches the results to $env{'form.scantron_maxbubble'},
9491: $env{'form.scantron.bubble_lines.n'},
9492: $env{'form.scantron.first_bubble_line.n'} and
9493: $env{"form.scantron.sub_bubblelines.n"}
9494: which are the total number of bubble, lines, the number of bubble
9495: lines for response n and number of the first bubble line for response n,
9496: and a comma separated list of numbers of bubble lines for sub-questions
9497: (for optionresponse, matchresponse, and rankresponse items), for response n.
9498:
9499:
9500: =item scantron_validate_missingbubbles() :
9501:
9502: Validates all scanlines in the selected file to not have any
9503: answers that don't have bubbles that have not been verified
9504: to be bubble free.
9505:
9506: =item scantron_process_students() :
9507:
9508: Routine that does the actual grading of the bubble sheet information.
9509:
9510: The parsed scanline hash is added to %env
9511:
9512: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9513: foreach resource , with the form data of
9514:
9515: 'submitted' =>'scantron'
9516: 'grade_target' =>'grade',
9517: 'grade_username'=> username of student
9518: 'grade_domain' => domain of student
9519: 'grade_courseid'=> of course
9520: 'grade_symb' => symb of resource to grade
9521:
9522: This triggers a grading pass. The problem grading code takes care
9523: of converting the bubbled letter information (now in %env) into a
9524: valid submission.
9525:
9526: =item scantron_upload_scantron_data() :
9527:
9528: Creates the screen for adding a new bubble sheet data file to a course.
9529:
9530: =item scantron_upload_scantron_data_save() :
9531:
9532: Adds a provided bubble information data file to the course if user
9533: has the correct privileges to do so.
9534:
9535: =item valid_file() :
9536:
9537: Validates that the requested bubble data file exists in the course.
9538:
9539: =item scantron_download_scantron_data() :
9540:
9541: Shows a list of the three internal files (original, corrected,
9542: skipped) for a specific bubble sheet data file that exists in the
9543: course.
9544:
9545: =item scantron_validate_ID() :
9546:
9547: Validates all scanlines in the selected file to not have any
1.556 weissno 9548: invalid or underspecified student/employee IDs
1.531 jms 9549:
1.582 raeburn 9550: =item navmap_errormsg() :
9551:
9552: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9553: Should be called whenever the request to instantiate a navmap object fails.
