4791:
1.424 albertel 4792: For this documentation:
4793:
4794: 'scanline' refers to the full line of characters
4795: from the file that we are parsing that represents one entire sheet
4796:
4797: 'bubble line' refers to the data
4798: representing the line of bubbles that are on the physical bubble sheet
4799:
4800:
4801: The overall process is that a scanned in bubble sheet data is uploaded
4802: into a course. When a user wants to grade, they select a
4803: sequence/folder of resources, a file of bubble sheet info, and pick
4804: one of the predefined configurations for what each scanline looks
4805: like.
4806:
4807: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4808: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4809: because too light bubbling), 'double bubble' (each bubble line should
4810: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4811: invalid student/employee ID
1.424 albertel 4812:
4813: If the CODE option is used that determines the randomization of the
1.556 weissno 4814: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4815: username:domain.
4816:
4817: During the validation phase the instructor can choose to skip scanlines.
4818:
1.435 foxr 4819: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4820:
4821: scantron_original_filename (unmodified original file)
4822: scantron_corrected_filename (file where the corrected information has replaced the original information)
4823: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4824:
4825: Also there is a separate hash nohist_scantrondata that contains extra
4826: correction information that isn't representable in the bubble sheet
4827: file (see &scantron_getfile() for more information)
4828:
4829: After all scanlines are either valid, marked as valid or skipped, then
4830: foreach line foreach problem in the picked sequence, an ssi request is
4831: made that simulates a user submitting their selected letter(s) against
4832: the homework problem.

9388: =head1 NAME
9389:
9390: Apache::grades
9391:
9392: =head1 SYNOPSIS
9393:
9394: Handles the viewing of grades.
9395:
9396: This is part of the LearningOnline Network with CAPA project
9397: described at http://www.lon-capa.org.
9398:
9399: =head1 OVERVIEW
9400:
9401: Do an ssi with retries:
9402: While I'd love to factor out this with the vesrion in lonprintout,
9403: 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
9404: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9405:
9406: At least the logic that drives this has been pulled out into loncommon.
9407:
9408:
9409:
9410: ssi_with_retries - Does the server side include of a resource.
9411: if the ssi call returns an error we'll retry it up to
9412: the number of times requested by the caller.
9413: If we still have a proble, no text is appended to the
9414: output and we set some global variables.
9415: to indicate to the caller an SSI error occurred.
9416: All of this is supposed to deal with the issues described
9417: in LonCAPA BZ 5631 see:
9418: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9419: by informing the user that this happened.
9420:
9421: Parameters:
9422: resource - The resource to include. This is passed directly, without
9423: interpretation to lonnet::ssi.
9424: form - The form hash parameters that guide the interpretation of the resource
9425:
9426: retries - Number of retries allowed before giving up completely.
9427: Returns:
9428: On success, returns the rendered resource identified by the resource parameter.
9429: Side Effects:
9430: The following global variables can be set:
9431: ssi_error - If an unrecoverable error occurred this becomes true.
9432: It is up to the caller to initialize this to false
9433: if desired.
9434: ssi_error_resource - If an unrecoverable error occurred, this is the value
9435: of the resource that could not be rendered by the ssi
9436: call.
9437: ssi_error_message - The error string fetched from the ssi response
9438: in the event of an error.

9449: =item scantron_get_correction() :
9450:
9451: Builds the interface screen to interact with the operator to fix a
9452: specific error condition in a specific scanline
9453:
9454: Arguments:
9455: $r - Apache request object
9456: $i - number of the current scanline
9457: $scan_record - hash ref as returned from &scantron_parse_scanline()
9458: $scan_config - hash ref as returned from &get_scantron_config()
9459: $line - full contents of the current scanline
9460: $error - error condition, valid values are
9461: 'incorrectCODE', 'duplicateCODE',
9462: 'doublebubble', 'missingbubble',
9463: 'duplicateID', 'incorrectID'
9464: $arg - extra information needed
9465: For errors:
9466: - duplicateID - paper number that this studentID was seen before on
9467: - duplicateCODE - array ref of the paper numbers this CODE was
9468: seen on before
9469: - incorrectCODE - current incorrect CODE
9470: - doublebubble - array ref of the bubble lines that have double
9471: bubble errors
9472: - missingbubble - array ref of the bubble lines that have missing
9473: bubble errors
9474:
9475: =item scantron_get_maxbubble() :
9476:
1.582 raeburn 9477: Arguments:
9478: $nav_error - Reference to scalar which is a flag to indicate a
9479: failure to retrieve a navmap object.
9480: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9481: calling routine should trap the error condition and display the warning
9482: found in &navmap_errormsg().
9483:
1.531 jms 9484: Returns the maximum number of bubble lines that are expected to
9485: occur. Does this by walking the selected sequence rendering the
9486: resource and then checking &Apache::lonxml::get_problem_counter()
9487: for what the current value of the problem counter is.
9488:
9489: Caches the results to $env{'form.scantron_maxbubble'},
9490: $env{'form.scantron.bubble_lines.n'},
9491: $env{'form.scantron.first_bubble_line.n'} and
9492: $env{"form.scantron.sub_bubblelines.n"}
9493: which are the total number of bubble, lines, the number of bubble
9494: lines for response n and number of the first bubble line for response n,
9495: and a comma separated list of numbers of bubble lines for sub-questions
9496: (for optionresponse, matchresponse, and rankresponse items), for response n.
9497:
9498:
9499: =item scantron_validate_missingbubbles() :

9503: to be bubble free.
9504:
9505: =item scantron_process_students() :
9506:
9507: Routine that does the actual grading of the bubble sheet information.
9508:
9509: The parsed scanline hash is added to %env
9510:
9511: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9512: foreach resource , with the form data of
9513:
9514: 'submitted' =>'scantron'
9515: 'grade_target' =>'grade',
9516: 'grade_username'=> username of student
9517: 'grade_domain' => domain of student
9518: 'grade_courseid'=> of course
9519: 'grade_symb' => symb of resource to grade
9520:
9521: This triggers a grading pass. The problem grading code takes care
9522: of converting the bubbled letter information (now in %env) into a
9523: valid submission.
9524:
9525: =item scantron_upload_scantron_data() :

9536: Validates that the requested bubble data file exists in the course.
9537:
9538: =item scantron_download_scantron_data() :
9539:
9540: Shows a list of the three internal files (original, corrected,
9541: skipped) for a specific bubble sheet data file that exists in the
9542: course.
9543:
9544: =item scantron_validate_ID() :
9545:
9546: Validates all scanlines in the selected file to not have any
1.556 weissno 9547: invalid or underspecified student/employee IDs
1.531 jms 9548:
1.582 raeburn 9549: =item navmap_errormsg() :
9550:
9551: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
