4758:
1.424 albertel 4759: For this documentation:
4760:
4761: 'scanline' refers to the full line of characters
4762: from the file that we are parsing that represents one entire sheet
4763:
4764: 'bubble line' refers to the data
4765: representing the line of bubbles that are on the physical bubble sheet
4766:
4767:
4768: The overall process is that a scanned in bubble sheet data is uploaded
4769: into a course. When a user wants to grade, they select a
4770: sequence/folder of resources, a file of bubble sheet info, and pick
4771: one of the predefined configurations for what each scanline looks
4772: like.
4773:
4774: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4775: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4776: because too light bubbling), 'double bubble' (each bubble line should
4777: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4778: invalid student/employee ID
1.424 albertel 4779:
4780: If the CODE option is used that determines the randomization of the
1.556 weissno 4781: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4782: username:domain.
4783:
4784: During the validation phase the instructor can choose to skip scanlines.
4785:
1.435 foxr 4786: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4787:
4788: scantron_original_filename (unmodified original file)
4789: scantron_corrected_filename (file where the corrected information has replaced the original information)
4790: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4791:
4792: Also there is a separate hash nohist_scantrondata that contains extra
4793: correction information that isn't representable in the bubble sheet
4794: file (see &scantron_getfile() for more information)
4795:
4796: After all scanlines are either valid, marked as valid or skipped, then
4797: foreach line foreach problem in the picked sequence, an ssi request is
4798: made that simulates a user submitting their selected letter(s) against
4799: the homework problem.

9314:
9315: Apache::grades
9316:
9317: =head1 SYNOPSIS
9318:
9319: Handles the viewing of grades.
9320:
9321: This is part of the LearningOnline Network with CAPA project
9322: described at http://www.lon-capa.org.
9323:
9324: =head1 OVERVIEW
9325:
9326: Do an ssi with retries:
9327: While I'd love to factor out this with the vesrion in lonprintout,
9328: 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
9329: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9330:
9331: At least the logic that drives this has been pulled out into loncommon.
9332:
9333:
9334:
9335: ssi_with_retries - Does the server side include of a resource.
9336: if the ssi call returns an error we'll retry it up to
9337: the number of times requested by the caller.
9338: If we still have a proble, no text is appended to the
9339: output and we set some global variables.
9340: to indicate to the caller an SSI error occurred.
9341: All of this is supposed to deal with the issues described
9342: in LonCAPA BZ 5631 see:
9343: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9344: by informing the user that this happened.
9345:
9346: Parameters:
9347: resource - The resource to include. This is passed directly, without
9348: interpretation to lonnet::ssi.
9349: form - The form hash parameters that guide the interpretation of the resource
9350:
9351: retries - Number of retries allowed before giving up completely.
9352: Returns:
9353: On success, returns the rendered resource identified by the resource parameter.
9354: Side Effects:
9355: The following global variables can be set:
9356: ssi_error - If an unrecoverable error occurred this becomes true.
9357: It is up to the caller to initialize this to false
9358: if desired.
9359: ssi_error_resource - If an unrecoverable error occurred, this is the value
9360: of the resource that could not be rendered by the ssi
9361: call.
9362: ssi_error_message - The error string fetched from the ssi response
9363: in the event of an error.

9373:
9374: =item scantron_get_correction() :
9375:
9376: Builds the interface screen to interact with the operator to fix a
9377: specific error condition in a specific scanline
9378:
9379: Arguments:
9380: $r - Apache request object
9381: $i - number of the current scanline
9382: $scan_record - hash ref as returned from &scantron_parse_scanline()
9383: $scan_config - hash ref as returned from &get_scantron_config()
9384: $line - full contents of the current scanline
9385: $error - error condition, valid values are
9386: 'incorrectCODE', 'duplicateCODE',
9387: 'doublebubble', 'missingbubble',
9388: 'duplicateID', 'incorrectID'
9389: $arg - extra information needed
9390: For errors:
9391: - duplicateID - paper number that this studentID was seen before on
9392: - duplicateCODE - array ref of the paper numbers this CODE was
9393: seen on before
9394: - incorrectCODE - current incorrect CODE
9395: - doublebubble - array ref of the bubble lines that have double
9396: bubble errors
9397: - missingbubble - array ref of the bubble lines that have missing
9398: bubble errors
9399:
9400: =item scantron_get_maxbubble() :
9401:
1.582 raeburn 9402: Arguments:
9403: $nav_error - Reference to scalar which is a flag to indicate a
9404: failure to retrieve a navmap object.
9405: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9406: calling routine should trap the error condition and display the warning
9407: found in &navmap_errormsg().
9408:
1.531 jms 9409: Returns the maximum number of bubble lines that are expected to
9410: occur. Does this by walking the selected sequence rendering the
9411: resource and then checking &Apache::lonxml::get_problem_counter()
9412: for what the current value of the problem counter is.
9413:
9414: Caches the results to $env{'form.scantron_maxbubble'},
9415: $env{'form.scantron.bubble_lines.n'},
9416: $env{'form.scantron.first_bubble_line.n'} and
9417: $env{"form.scantron.sub_bubblelines.n"}
9418: which are the total number of bubble, lines, the number of bubble
9419: lines for response n and number of the first bubble line for response n,
9420: and a comma separated list of numbers of bubble lines for sub-questions
9421: (for optionresponse, matchresponse, and rankresponse items), for response n.
9422:
9423:
9424: =item scantron_validate_missingbubbles() :
9425:
9426: Validates all scanlines in the selected file to not have any
9427: answers that don't have bubbles that have not been verified
9428: to be bubble free.
9429:
9430: =item scantron_process_students() :
9431:
9432: Routine that does the actual grading of the bubble sheet information.
9433:
9434: The parsed scanline hash is added to %env
9435:
9436: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9437: foreach resource , with the form data of
9438:
9439: 'submitted' =>'scantron'
9440: 'grade_target' =>'grade',
9441: 'grade_username'=> username of student
9442: 'grade_domain' => domain of student
9443: 'grade_courseid'=> of course
9444: 'grade_symb' => symb of resource to grade
9445:
9446: This triggers a grading pass. The problem grading code takes care
9447: of converting the bubbled letter information (now in %env) into a
9448: valid submission.
9449:
9450: =item scantron_upload_scantron_data() :
9451:
9452: Creates the screen for adding a new bubble sheet data file to a course.
9453:
9454: =item scantron_upload_scantron_data_save() :
9455:
9456: Adds a provided bubble information data file to the course if user
9457: has the correct privileges to do so.
9458:
9459: =item valid_file() :
9460:
9461: Validates that the requested bubble data file exists in the course.
9462:
9463: =item scantron_download_scantron_data() :
9464:
9465: Shows a list of the three internal files (original, corrected,
9466: skipped) for a specific bubble sheet data file that exists in the
9467: course.
9468:
9469: =item scantron_validate_ID() :
9470:
9471: Validates all scanlines in the selected file to not have any
1.556 weissno 9472: invalid or underspecified student/employee IDs
1.531 jms 9473:
1.582 raeburn 9474: =item navmap_errormsg() :
9475:
9476: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9477: Should be called whenever the request to instantiate a navmap object fails.
