4768:
1.424 albertel 4769: For this documentation:
4770:
4771: 'scanline' refers to the full line of characters
4772: from the file that we are parsing that represents one entire sheet
4773:
4774: 'bubble line' refers to the data
4775: representing the line of bubbles that are on the physical bubble sheet
4776:
4777:
4778: The overall process is that a scanned in bubble sheet data is uploaded
4779: into a course. When a user wants to grade, they select a
4780: sequence/folder of resources, a file of bubble sheet info, and pick
4781: one of the predefined configurations for what each scanline looks
4782: like.
4783:
4784: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4785: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4786: because too light bubbling), 'double bubble' (each bubble line should
4787: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4788: invalid student/employee ID
1.424 albertel 4789:
4790: If the CODE option is used that determines the randomization of the
1.556 weissno 4791: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4792: username:domain.
4793:
4794: During the validation phase the instructor can choose to skip scanlines.
4795:
1.435 foxr 4796: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4797:
4798: scantron_original_filename (unmodified original file)
4799: scantron_corrected_filename (file where the corrected information has replaced the original information)
4800: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4801:
4802: Also there is a separate hash nohist_scantrondata that contains extra
4803: correction information that isn't representable in the bubble sheet
4804: file (see &scantron_getfile() for more information)
4805:
4806: After all scanlines are either valid, marked as valid or skipped, then
4807: foreach line foreach problem in the picked sequence, an ssi request is
4808: made that simulates a user submitting their selected letter(s) against
4809: the homework problem.

9370: =head1 NAME
9371:
9372: Apache::grades
9373:
9374: =head1 SYNOPSIS
9375:
9376: Handles the viewing of grades.
9377:
9378: This is part of the LearningOnline Network with CAPA project
9379: described at http://www.lon-capa.org.
9380:
9381: =head1 OVERVIEW
9382:
9383: Do an ssi with retries:
9384: While I'd love to factor out this with the vesrion in lonprintout,
9385: 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
9386: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9387:
9388: At least the logic that drives this has been pulled out into loncommon.
9389:
9390:
9391:
9392: ssi_with_retries - Does the server side include of a resource.
9393: if the ssi call returns an error we'll retry it up to
9394: the number of times requested by the caller.
9395: If we still have a proble, no text is appended to the
9396: output and we set some global variables.
9397: to indicate to the caller an SSI error occurred.
9398: All of this is supposed to deal with the issues described
9399: in LonCAPA BZ 5631 see:
9400: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9401: by informing the user that this happened.
9402:
9403: Parameters:
9404: resource - The resource to include. This is passed directly, without
9405: interpretation to lonnet::ssi.
9406: form - The form hash parameters that guide the interpretation of the resource
9407:
9408: retries - Number of retries allowed before giving up completely.
9409: Returns:
9410: On success, returns the rendered resource identified by the resource parameter.
9411: Side Effects:
9412: The following global variables can be set:
9413: ssi_error - If an unrecoverable error occurred this becomes true.
9414: It is up to the caller to initialize this to false
9415: if desired.
9416: ssi_error_resource - If an unrecoverable error occurred, this is the value
9417: of the resource that could not be rendered by the ssi
9418: call.
9419: ssi_error_message - The error string fetched from the ssi response
9420: in the event of an error.

9430:
9431: =item scantron_get_correction() :
9432:
9433: Builds the interface screen to interact with the operator to fix a
9434: specific error condition in a specific scanline
9435:
9436: Arguments:
9437: $r - Apache request object
9438: $i - number of the current scanline
9439: $scan_record - hash ref as returned from &scantron_parse_scanline()
9440: $scan_config - hash ref as returned from &get_scantron_config()
9441: $line - full contents of the current scanline
9442: $error - error condition, valid values are
9443: 'incorrectCODE', 'duplicateCODE',
9444: 'doublebubble', 'missingbubble',
9445: 'duplicateID', 'incorrectID'
9446: $arg - extra information needed
9447: For errors:
9448: - duplicateID - paper number that this studentID was seen before on
9449: - duplicateCODE - array ref of the paper numbers this CODE was
9450: seen on before
9451: - incorrectCODE - current incorrect CODE
9452: - doublebubble - array ref of the bubble lines that have double
9453: bubble errors
9454: - missingbubble - array ref of the bubble lines that have missing
9455: bubble errors
9456:
9457: =item scantron_get_maxbubble() :
9458:
1.582 raeburn 9459: Arguments:
9460: $nav_error - Reference to scalar which is a flag to indicate a
9461: failure to retrieve a navmap object.
9462: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9463: calling routine should trap the error condition and display the warning
9464: found in &navmap_errormsg().
9465:
1.531 jms 9466: Returns the maximum number of bubble lines that are expected to
9467: occur. Does this by walking the selected sequence rendering the
9468: resource and then checking &Apache::lonxml::get_problem_counter()
9469: for what the current value of the problem counter is.
9470:
9471: Caches the results to $env{'form.scantron_maxbubble'},
9472: $env{'form.scantron.bubble_lines.n'},
9473: $env{'form.scantron.first_bubble_line.n'} and
9474: $env{"form.scantron.sub_bubblelines.n"}
9475: which are the total number of bubble, lines, the number of bubble
9476: lines for response n and number of the first bubble line for response n,
9477: and a comma separated list of numbers of bubble lines for sub-questions
9478: (for optionresponse, matchresponse, and rankresponse items), for response n.
9479:
9480:
9481: =item scantron_validate_missingbubbles() :
9482:
9483: Validates all scanlines in the selected file to not have any
9484: answers that don't have bubbles that have not been verified
9485: to be bubble free.
9486:
9487: =item scantron_process_students() :
9488:
9489: Routine that does the actual grading of the bubble sheet information.
9490:
9491: The parsed scanline hash is added to %env
9492:
9493: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9494: foreach resource , with the form data of
9495:
9496: 'submitted' =>'scantron'
9497: 'grade_target' =>'grade',
9498: 'grade_username'=> username of student
9499: 'grade_domain' => domain of student
9500: 'grade_courseid'=> of course
9501: 'grade_symb' => symb of resource to grade
9502:
9503: This triggers a grading pass. The problem grading code takes care
9504: of converting the bubbled letter information (now in %env) into a
9505: valid submission.
9506:
9507: =item scantron_upload_scantron_data() :
9508:
9509: Creates the screen for adding a new bubble sheet data file to a course.
9510:
9511: =item scantron_upload_scantron_data_save() :
9512:
9513: Adds a provided bubble information data file to the course if user
9514: has the correct privileges to do so.
9515:
9516: =item valid_file() :
9517:
9518: Validates that the requested bubble data file exists in the course.
9519:
9520: =item scantron_download_scantron_data() :
9521:
9522: Shows a list of the three internal files (original, corrected,
9523: skipped) for a specific bubble sheet data file that exists in the
9524: course.
9525:
9526: =item scantron_validate_ID() :
9527:
9528: Validates all scanlines in the selected file to not have any
1.556 weissno 9529: invalid or underspecified student/employee IDs
1.531 jms 9530:
1.582 raeburn 9531: =item navmap_errormsg() :
9532:
9533: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9534: Should be called whenever the request to instantiate a navmap object fails.
