4770:
1.424 albertel 4771: For this documentation:
4772:
4773: 'scanline' refers to the full line of characters
4774: from the file that we are parsing that represents one entire sheet
4775:
4776: 'bubble line' refers to the data
4777: representing the line of bubbles that are on the physical bubble sheet
4778:
4779:
4780: The overall process is that a scanned in bubble sheet data is uploaded
4781: into a course. When a user wants to grade, they select a
4782: sequence/folder of resources, a file of bubble sheet info, and pick
4783: one of the predefined configurations for what each scanline looks
4784: like.
4785:
4786: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4787: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4788: because too light bubbling), 'double bubble' (each bubble line should
4789: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4790: invalid student/employee ID
1.424 albertel 4791:
4792: If the CODE option is used that determines the randomization of the
1.556 weissno 4793: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4794: username:domain.
4795:
4796: During the validation phase the instructor can choose to skip scanlines.
4797:
1.435 foxr 4798: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4799:
4800: scantron_original_filename (unmodified original file)
4801: scantron_corrected_filename (file where the corrected information has replaced the original information)
4802: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4803:
4804: Also there is a separate hash nohist_scantrondata that contains extra
4805: correction information that isn't representable in the bubble sheet
4806: file (see &scantron_getfile() for more information)
4807:
4808: After all scanlines are either valid, marked as valid or skipped, then
4809: foreach line foreach problem in the picked sequence, an ssi request is
4810: made that simulates a user submitting their selected letter(s) against
4811: the homework problem.

9372: =head1 NAME
9373:
9374: Apache::grades
9375:
9376: =head1 SYNOPSIS
9377:
9378: Handles the viewing of grades.
9379:
9380: This is part of the LearningOnline Network with CAPA project
9381: described at http://www.lon-capa.org.
9382:
9383: =head1 OVERVIEW
9384:
9385: Do an ssi with retries:
9386: While I'd love to factor out this with the vesrion in lonprintout,
9387: 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
9388: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9389:
9390: At least the logic that drives this has been pulled out into loncommon.
9391:
9392:
9393:
9394: ssi_with_retries - Does the server side include of a resource.
9395: if the ssi call returns an error we'll retry it up to
9396: the number of times requested by the caller.
9397: If we still have a proble, no text is appended to the
9398: output and we set some global variables.
9399: to indicate to the caller an SSI error occurred.
9400: All of this is supposed to deal with the issues described
9401: in LonCAPA BZ 5631 see:
9402: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9403: by informing the user that this happened.
9404:
9405: Parameters:
9406: resource - The resource to include. This is passed directly, without
9407: interpretation to lonnet::ssi.
9408: form - The form hash parameters that guide the interpretation of the resource
9409:
9410: retries - Number of retries allowed before giving up completely.
9411: Returns:
9412: On success, returns the rendered resource identified by the resource parameter.
9413: Side Effects:
9414: The following global variables can be set:
9415: ssi_error - If an unrecoverable error occurred this becomes true.
9416: It is up to the caller to initialize this to false
9417: if desired.
9418: ssi_error_resource - If an unrecoverable error occurred, this is the value
9419: of the resource that could not be rendered by the ssi
9420: call.
9421: ssi_error_message - The error string fetched from the ssi response
9422: in the event of an error.

9432:
9433: =item scantron_get_correction() :
9434:
9435: Builds the interface screen to interact with the operator to fix a
9436: specific error condition in a specific scanline
9437:
9438: Arguments:
9439: $r - Apache request object
9440: $i - number of the current scanline
9441: $scan_record - hash ref as returned from &scantron_parse_scanline()
9442: $scan_config - hash ref as returned from &get_scantron_config()
9443: $line - full contents of the current scanline
9444: $error - error condition, valid values are
9445: 'incorrectCODE', 'duplicateCODE',
9446: 'doublebubble', 'missingbubble',
9447: 'duplicateID', 'incorrectID'
9448: $arg - extra information needed
9449: For errors:
9450: - duplicateID - paper number that this studentID was seen before on
9451: - duplicateCODE - array ref of the paper numbers this CODE was
9452: seen on before
9453: - incorrectCODE - current incorrect CODE
9454: - doublebubble - array ref of the bubble lines that have double
9455: bubble errors
9456: - missingbubble - array ref of the bubble lines that have missing
9457: bubble errors
9458:
9459: =item scantron_get_maxbubble() :
9460:
1.582 raeburn 9461: Arguments:
9462: $nav_error - Reference to scalar which is a flag to indicate a
9463: failure to retrieve a navmap object.
9464: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9465: calling routine should trap the error condition and display the warning
9466: found in &navmap_errormsg().
9467:
1.531 jms 9468: Returns the maximum number of bubble lines that are expected to
9469: occur. Does this by walking the selected sequence rendering the
9470: resource and then checking &Apache::lonxml::get_problem_counter()
9471: for what the current value of the problem counter is.
9472:
9473: Caches the results to $env{'form.scantron_maxbubble'},
9474: $env{'form.scantron.bubble_lines.n'},
9475: $env{'form.scantron.first_bubble_line.n'} and
9476: $env{"form.scantron.sub_bubblelines.n"}
9477: which are the total number of bubble, lines, the number of bubble
9478: lines for response n and number of the first bubble line for response n,
9479: and a comma separated list of numbers of bubble lines for sub-questions
9480: (for optionresponse, matchresponse, and rankresponse items), for response n.
9481:
9482:
9483: =item scantron_validate_missingbubbles() :
9484:
9485: Validates all scanlines in the selected file to not have any
9486: answers that don't have bubbles that have not been verified
9487: to be bubble free.
9488:
9489: =item scantron_process_students() :
9490:
9491: Routine that does the actual grading of the bubble sheet information.
9492:
9493: The parsed scanline hash is added to %env
9494:
9495: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9496: foreach resource , with the form data of
9497:
9498: 'submitted' =>'scantron'
9499: 'grade_target' =>'grade',
9500: 'grade_username'=> username of student
9501: 'grade_domain' => domain of student
9502: 'grade_courseid'=> of course
9503: 'grade_symb' => symb of resource to grade
9504:
9505: This triggers a grading pass. The problem grading code takes care
9506: of converting the bubbled letter information (now in %env) into a
9507: valid submission.
9508:
9509: =item scantron_upload_scantron_data() :
9510:
9511: Creates the screen for adding a new bubble sheet data file to a course.
9512:
9513: =item scantron_upload_scantron_data_save() :
9514:
9515: Adds a provided bubble information data file to the course if user
9516: has the correct privileges to do so.
9517:
9518: =item valid_file() :
9519:
9520: Validates that the requested bubble data file exists in the course.
9521:
9522: =item scantron_download_scantron_data() :
9523:
9524: Shows a list of the three internal files (original, corrected,
9525: skipped) for a specific bubble sheet data file that exists in the
9526: course.
9527:
9528: =item scantron_validate_ID() :
9529:
9530: Validates all scanlines in the selected file to not have any
1.556 weissno 9531: invalid or underspecified student/employee IDs
1.531 jms 9532:
1.582 raeburn 9533: =item navmap_errormsg() :
9534:
9535: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9536: Should be called whenever the request to instantiate a navmap object fails.
