4753:
1.424 albertel 4754: For this documentation:
4755:
4756: 'scanline' refers to the full line of characters
4757: from the file that we are parsing that represents one entire sheet
4758:
4759: 'bubble line' refers to the data
4760: representing the line of bubbles that are on the physical bubble sheet
4761:
4762:
4763: The overall process is that a scanned in bubble sheet data is uploaded
4764: into a course. When a user wants to grade, they select a
4765: sequence/folder of resources, a file of bubble sheet info, and pick
4766: one of the predefined configurations for what each scanline looks
4767: like.
4768:
4769: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4770: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4771: because too light bubbling), 'double bubble' (each bubble line should
4772: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4773: invalid student/employee ID
1.424 albertel 4774:
4775: If the CODE option is used that determines the randomization of the
1.556 weissno 4776: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4777: username:domain.
4778:
4779: During the validation phase the instructor can choose to skip scanlines.
4780:
1.435 foxr 4781: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4782:
4783: scantron_original_filename (unmodified original file)
4784: scantron_corrected_filename (file where the corrected information has replaced the original information)
4785: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4786:
4787: Also there is a separate hash nohist_scantrondata that contains extra
4788: correction information that isn't representable in the bubble sheet
4789: file (see &scantron_getfile() for more information)
4790:
4791: After all scanlines are either valid, marked as valid or skipped, then
4792: foreach line foreach problem in the picked sequence, an ssi request is
4793: made that simulates a user submitting their selected letter(s) against
4794: the homework problem.

9363: =head1 NAME
9364:
9365: Apache::grades
9366:
9367: =head1 SYNOPSIS
9368:
9369: Handles the viewing of grades.
9370:
9371: This is part of the LearningOnline Network with CAPA project
9372: described at http://www.lon-capa.org.
9373:
9374: =head1 OVERVIEW
9375:
9376: Do an ssi with retries:
9377: While I'd love to factor out this with the vesrion in lonprintout,
9378: 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
9379: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9380:
9381: At least the logic that drives this has been pulled out into loncommon.
9382:
9383:
9384:
9385: ssi_with_retries - Does the server side include of a resource.
9386: if the ssi call returns an error we'll retry it up to
9387: the number of times requested by the caller.
9388: If we still have a proble, no text is appended to the
9389: output and we set some global variables.
9390: to indicate to the caller an SSI error occurred.
9391: All of this is supposed to deal with the issues described
9392: in LonCAPA BZ 5631 see:
9393: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9394: by informing the user that this happened.
9395:
9396: Parameters:
9397: resource - The resource to include. This is passed directly, without
9398: interpretation to lonnet::ssi.
9399: form - The form hash parameters that guide the interpretation of the resource
9400:
9401: retries - Number of retries allowed before giving up completely.
9402: Returns:
9403: On success, returns the rendered resource identified by the resource parameter.
9404: Side Effects:
9405: The following global variables can be set:
9406: ssi_error - If an unrecoverable error occurred this becomes true.
9407: It is up to the caller to initialize this to false
9408: if desired.
9409: ssi_error_resource - If an unrecoverable error occurred, this is the value
9410: of the resource that could not be rendered by the ssi
9411: call.
9412: ssi_error_message - The error string fetched from the ssi response
9413: in the event of an error.

9423:
9424: =item scantron_get_correction() :
9425:
9426: Builds the interface screen to interact with the operator to fix a
9427: specific error condition in a specific scanline
9428:
9429: Arguments:
9430: $r - Apache request object
9431: $i - number of the current scanline
9432: $scan_record - hash ref as returned from &scantron_parse_scanline()
9433: $scan_config - hash ref as returned from &get_scantron_config()
9434: $line - full contents of the current scanline
9435: $error - error condition, valid values are
9436: 'incorrectCODE', 'duplicateCODE',
9437: 'doublebubble', 'missingbubble',
9438: 'duplicateID', 'incorrectID'
9439: $arg - extra information needed
9440: For errors:
9441: - duplicateID - paper number that this studentID was seen before on
9442: - duplicateCODE - array ref of the paper numbers this CODE was
9443: seen on before
9444: - incorrectCODE - current incorrect CODE
9445: - doublebubble - array ref of the bubble lines that have double
9446: bubble errors
9447: - missingbubble - array ref of the bubble lines that have missing
9448: bubble errors
9449:
9450: =item scantron_get_maxbubble() :
9451:
1.582 raeburn 9452: Arguments:
9453: $nav_error - Reference to scalar which is a flag to indicate a
9454: failure to retrieve a navmap object.
9455: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9456: calling routine should trap the error condition and display the warning
9457: found in &navmap_errormsg().
9458:
1.531 jms 9459: Returns the maximum number of bubble lines that are expected to
9460: occur. Does this by walking the selected sequence rendering the
9461: resource and then checking &Apache::lonxml::get_problem_counter()
9462: for what the current value of the problem counter is.
9463:
9464: Caches the results to $env{'form.scantron_maxbubble'},
9465: $env{'form.scantron.bubble_lines.n'},
9466: $env{'form.scantron.first_bubble_line.n'} and
9467: $env{"form.scantron.sub_bubblelines.n"}
9468: which are the total number of bubble, lines, the number of bubble
9469: lines for response n and number of the first bubble line for response n,
9470: and a comma separated list of numbers of bubble lines for sub-questions
9471: (for optionresponse, matchresponse, and rankresponse items), for response n.
9472:
9473:
9474: =item scantron_validate_missingbubbles() :
9475:
9476: Validates all scanlines in the selected file to not have any
9477: answers that don't have bubbles that have not been verified
9478: to be bubble free.
9479:
9480: =item scantron_process_students() :
9481:
9482: Routine that does the actual grading of the bubble sheet information.
9483:
9484: The parsed scanline hash is added to %env
9485:
9486: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9487: foreach resource , with the form data of
9488:
9489: 'submitted' =>'scantron'
9490: 'grade_target' =>'grade',
9491: 'grade_username'=> username of student
9492: 'grade_domain' => domain of student
9493: 'grade_courseid'=> of course
9494: 'grade_symb' => symb of resource to grade
9495:
9496: This triggers a grading pass. The problem grading code takes care
9497: of converting the bubbled letter information (now in %env) into a
9498: valid submission.
9499:
9500: =item scantron_upload_scantron_data() :
9501:
9502: Creates the screen for adding a new bubble sheet data file to a course.
9503:
9504: =item scantron_upload_scantron_data_save() :
9505:
9506: Adds a provided bubble information data file to the course if user
9507: has the correct privileges to do so.
9508:
9509: =item valid_file() :
9510:
9511: Validates that the requested bubble data file exists in the course.
9512:
9513: =item scantron_download_scantron_data() :
9514:
9515: Shows a list of the three internal files (original, corrected,
9516: skipped) for a specific bubble sheet data file that exists in the
9517: course.
9518:
9519: =item scantron_validate_ID() :
9520:
9521: Validates all scanlines in the selected file to not have any
1.556 weissno 9522: invalid or underspecified student/employee IDs
1.531 jms 9523:
1.582 raeburn 9524: =item navmap_errormsg() :
9525:
9526: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9527: Should be called whenever the request to instantiate a navmap object fails.
