4768: =head1 Bubble sheet grading routines
4769:
4770: For this documentation:
4771:
4772: 'scanline' refers to the full line of characters
4773: from the file that we are parsing that represents one entire sheet
4774:
4775: 'bubble line' refers to the data
4776: representing the line of bubbles that are on the physical bubble sheet
4777:
4778:
4779: The overall process is that a scanned in bubble sheet data is uploaded
4780: into a course. When a user wants to grade, they select a
4781: sequence/folder of resources, a file of bubble sheet info, and pick
4782: one of the predefined configurations for what each scanline looks
4783: like.
4784:
4785: Next each scanline is checked for any errors of either 'missing
4786: bubbles' (it's an error because it may have been mis-scanned
4787: because too light bubbling), 'double bubble' (each bubble line should
4788: have no more that one letter picked), invalid or duplicated CODE,
4789: invalid student/employee ID
4790:
4791: If the CODE option is used that determines the randomization of the
4792: homework problems, either way the student/employee ID is looked up into a
4793: username:domain.
4794:
4795: During the validation phase the instructor can choose to skip scanlines.
4796:
4797: After the validation phase, there are now 3 bubble sheet files
4798:
4799: scantron_original_filename (unmodified original file)
4800: scantron_corrected_filename (file where the corrected information has replaced the original information)
4801: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4802:
4803: Also there is a separate hash nohist_scantrondata that contains extra
4804: correction information that isn't representable in the bubble sheet
4805: file (see &scantron_getfile() for more information)
4806:
4807: After all scanlines are either valid, marked as valid or skipped, then
4808: foreach line foreach problem in the picked sequence, an ssi request is
4809: made that simulates a user submitting their selected letter(s) against
4810: the homework problem.

9335: =head1 NAME
9336:
9337: Apache::grades
9338:
9339: =head1 SYNOPSIS
9340:
9341: Handles the viewing of grades.
9342:
9343: This is part of the LearningOnline Network with CAPA project
9344: described at http://www.lon-capa.org.
9345:
9346: =head1 OVERVIEW
9347:
9348: Do an ssi with retries:
9349: While I'd love to factor out this with the vesrion in lonprintout,
9350: 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
9351: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9352:
9353: At least the logic that drives this has been pulled out into loncommon.
9354:
9355:
9356:
9357: ssi_with_retries - Does the server side include of a resource.
9358: if the ssi call returns an error we'll retry it up to
9359: the number of times requested by the caller.
9360: If we still have a proble, no text is appended to the
9361: output and we set some global variables.
9362: to indicate to the caller an SSI error occurred.
9363: All of this is supposed to deal with the issues described
9364: in LonCAPA BZ 5631 see:
9365: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9366: by informing the user that this happened.
9367:
9368: Parameters:
9369: resource - The resource to include. This is passed directly, without
9370: interpretation to lonnet::ssi.
9371: form - The form hash parameters that guide the interpretation of the resource
9372:
9373: retries - Number of retries allowed before giving up completely.
9374: Returns:
9375: On success, returns the rendered resource identified by the resource parameter.
9376: Side Effects:
9377: The following global variables can be set:
9378: ssi_error - If an unrecoverable error occurred this becomes true.
9379: It is up to the caller to initialize this to false
9380: if desired.
9381: ssi_error_resource - If an unrecoverable error occurred, this is the value
9382: of the resource that could not be rendered by the ssi
9383: call.
9384: ssi_error_message - The error string fetched from the ssi response
9385: in the event of an error.

9396: =item scantron_get_correction() :
9397:
9398: Builds the interface screen to interact with the operator to fix a
9399: specific error condition in a specific scanline
9400:
9401: Arguments:
9402: $r - Apache request object
9403: $i - number of the current scanline
9404: $scan_record - hash ref as returned from &scantron_parse_scanline()
9405: $scan_config - hash ref as returned from &get_scantron_config()
9406: $line - full contents of the current scanline
9407: $error - error condition, valid values are
9408: 'incorrectCODE', 'duplicateCODE',
9409: 'doublebubble', 'missingbubble',
9410: 'duplicateID', 'incorrectID'
9411: $arg - extra information needed
9412: For errors:
9413: - duplicateID - paper number that this studentID was seen before on
9414: - duplicateCODE - array ref of the paper numbers this CODE was
9415: seen on before
9416: - incorrectCODE - current incorrect CODE
9417: - doublebubble - array ref of the bubble lines that have double
9418: bubble errors
9419: - missingbubble - array ref of the bubble lines that have missing
9420: bubble errors
9421:
9422: =item scantron_get_maxbubble() :
9423:
9424: Arguments:
9425: $nav_error - Reference to scalar which is a flag to indicate a
9426: failure to retrieve a navmap object.
9427: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9428: calling routine should trap the error condition and display the warning
9429: found in &navmap_errormsg().
9430:
9431: Returns the maximum number of bubble lines that are expected to
9432: occur. Does this by walking the selected sequence rendering the
9433: resource and then checking &Apache::lonxml::get_problem_counter()
9434: for what the current value of the problem counter is.
9435:
9436: Caches the results to $env{'form.scantron_maxbubble'},
9437: $env{'form.scantron.bubble_lines.n'},
9438: $env{'form.scantron.first_bubble_line.n'} and
9439: $env{"form.scantron.sub_bubblelines.n"}
9440: which are the total number of bubble, lines, the number of bubble
9441: lines for response n and number of the first bubble line for response n,
9442: and a comma separated list of numbers of bubble lines for sub-questions
9443: (for optionresponse, matchresponse, and rankresponse items), for response n.
9444:
9445:
9446: =item scantron_validate_missingbubbles() :
9447:
9448: Validates all scanlines in the selected file to not have any
9449: answers that don't have bubbles that have not been verified
9450: to be bubble free.
9451:
9452: =item scantron_process_students() :
9453:
9454: Routine that does the actual grading of the bubble sheet information.
9455:
9456: The parsed scanline hash is added to %env
9457:
9458: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9459: foreach resource , with the form data of
9460:
9461: 'submitted' =>'scantron'
9462: 'grade_target' =>'grade',
9463: 'grade_username'=> username of student
9464: 'grade_domain' => domain of student
9465: 'grade_courseid'=> of course
9466: 'grade_symb' => symb of resource to grade
9467:
9468: This triggers a grading pass. The problem grading code takes care
9469: of converting the bubbled letter information (now in %env) into a
9470: valid submission.
9471:
9472: =item scantron_upload_scantron_data() :
9473:
9474: Creates the screen for adding a new bubble sheet data file to a course.
9475:
9476: =item scantron_upload_scantron_data_save() :
9477:
9478: Adds a provided bubble information data file to the course if user
9479: has the correct privileges to do so.
9480:
9481: =item valid_file() :
9482:
9483: Validates that the requested bubble data file exists in the course.
9484:
9485: =item scantron_download_scantron_data() :
9486:
9487: Shows a list of the three internal files (original, corrected,
9488: skipped) for a specific bubble sheet data file that exists in the
9489: course.
9490:
9491: =item scantron_validate_ID() :
9492:
9493: Validates all scanlines in the selected file to not have any
9494: invalid or underspecified student/employee IDs
9495:
9496: =item navmap_errormsg() :
9497:
9498: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9499: Should be called whenever the request to instantiate a navmap object fails.
