4855: The overall process is that a scanned in bubble sheet data is uploaded
4856: into a course. When a user wants to grade, they select a
4857: sequence/folder of resources, a file of bubble sheet info, and pick
4858: one of the predefined configurations for what each scanline looks
4859: like.
4860:
4861: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4862: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4863: because too light bubbling), 'double bubble' (each bubble line should
4864: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4865: invalid student/employee ID
1.424 albertel 4866:
4867: If the CODE option is used that determines the randomization of the
1.556 weissno 4868: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4869: username:domain.
4870:
4871: During the validation phase the instructor can choose to skip scanlines.
4872:
1.435 foxr 4873: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4874:
4875: scantron_original_filename (unmodified original file)
4876: scantron_corrected_filename (file where the corrected information has replaced the original information)
4877: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4878:
4879: Also there is a separate hash nohist_scantrondata that contains extra
4880: correction information that isn't representable in the bubble sheet
4881: file (see &scantron_getfile() for more information)
4882:
4883: After all scanlines are either valid, marked as valid or skipped, then
4884: foreach line foreach problem in the picked sequence, an ssi request is
4885: made that simulates a user submitting their selected letter(s) against
4886: the homework problem.

9391: =head1 NAME
9392:
9393: Apache::grades
9394:
9395: =head1 SYNOPSIS
9396:
9397: Handles the viewing of grades.
9398:
9399: This is part of the LearningOnline Network with CAPA project
9400: described at http://www.lon-capa.org.
9401:
9402: =head1 OVERVIEW
9403:
9404: Do an ssi with retries:
9405: While I'd love to factor out this with the vesrion in lonprintout,
9406: 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
9407: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9408:
9409: At least the logic that drives this has been pulled out into loncommon.
9410:
9411:
9412:
9413: ssi_with_retries - Does the server side include of a resource.
9414: if the ssi call returns an error we'll retry it up to
9415: the number of times requested by the caller.
9416: If we still have a proble, no text is appended to the
9417: output and we set some global variables.
9418: to indicate to the caller an SSI error occurred.
9419: All of this is supposed to deal with the issues described
9420: in LonCAPA BZ 5631 see:
9421: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9422: by informing the user that this happened.
9423:
9424: Parameters:
9425: resource - The resource to include. This is passed directly, without
9426: interpretation to lonnet::ssi.
9427: form - The form hash parameters that guide the interpretation of the resource
9428:
9429: retries - Number of retries allowed before giving up completely.
9430: Returns:
9431: On success, returns the rendered resource identified by the resource parameter.
9432: Side Effects:
9433: The following global variables can be set:
9434: ssi_error - If an unrecoverable error occurred this becomes true.
9435: It is up to the caller to initialize this to false
9436: if desired.
9437: ssi_error_resource - If an unrecoverable error occurred, this is the value
9438: of the resource that could not be rendered by the ssi
9439: call.
9440: ssi_error_message - The error string fetched from the ssi response
9441: in the event of an error.

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

9533:
9534: Adds a provided bubble information data file to the course if user
9535: has the correct privileges to do so.

9537: =item valid_file() :
9538:
9539: Validates that the requested bubble data file exists in the course.
9540:
9541: =item scantron_download_scantron_data() :
9542:
9543: Shows a list of the three internal files (original, corrected,
9544: skipped) for a specific bubble sheet data file that exists in the
9545: course.
9546:
9547: =item scantron_validate_ID() :
9548:
9549: Validates all scanlines in the selected file to not have any

1.531 jms 9551:
1.582 raeburn 9552: =item navmap_errormsg() :
9553:
9554: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
