4757:
1.424 albertel 4758: For this documentation:
4759:
4760: 'scanline' refers to the full line of characters
4761: from the file that we are parsing that represents one entire sheet
4762:
4763: 'bubble line' refers to the data
4764: representing the line of bubbles that are on the physical bubble sheet
4765:
4766:
4767: The overall process is that a scanned in bubble sheet data is uploaded
4768: into a course. When a user wants to grade, they select a
4769: sequence/folder of resources, a file of bubble sheet info, and pick
4770: one of the predefined configurations for what each scanline looks
4771: like.
4772:
4773: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4774: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4775: because too light bubbling), 'double bubble' (each bubble line should
4776: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4777: invalid student/employee ID
1.424 albertel 4778:
4779: If the CODE option is used that determines the randomization of the
1.556 weissno 4780: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4781: username:domain.
4782:
4783: During the validation phase the instructor can choose to skip scanlines.
4784:
1.435 foxr 4785: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4786:
4787: scantron_original_filename (unmodified original file)
4788: scantron_corrected_filename (file where the corrected information has replaced the original information)
4789: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4790:
4791: Also there is a separate hash nohist_scantrondata that contains extra
4792: correction information that isn't representable in the bubble sheet
4793: file (see &scantron_getfile() for more information)
4794:
4795: After all scanlines are either valid, marked as valid or skipped, then
4796: foreach line foreach problem in the picked sequence, an ssi request is
4797: made that simulates a user submitting their selected letter(s) against
4798: the homework problem.

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

9372: =item scantron_get_correction() :
9373:
9374: Builds the interface screen to interact with the operator to fix a
9375: specific error condition in a specific scanline
9376:
9377: Arguments:
9378: $r - Apache request object
9379: $i - number of the current scanline
9380: $scan_record - hash ref as returned from &scantron_parse_scanline()
9381: $scan_config - hash ref as returned from &get_scantron_config()
9382: $line - full contents of the current scanline
9383: $error - error condition, valid values are
9384: 'incorrectCODE', 'duplicateCODE',
9385: 'doublebubble', 'missingbubble',
9386: 'duplicateID', 'incorrectID'
9387: $arg - extra information needed
9388: For errors:
9389: - duplicateID - paper number that this studentID was seen before on
9390: - duplicateCODE - array ref of the paper numbers this CODE was
9391: seen on before
9392: - incorrectCODE - current incorrect CODE
9393: - doublebubble - array ref of the bubble lines that have double
9394: bubble errors
9395: - missingbubble - array ref of the bubble lines that have missing
9396: bubble errors
9397:
9398: =item scantron_get_maxbubble() :

1.582 raeburn 9400: Arguments:
9401: $nav_error - Reference to scalar which is a flag to indicate a
9402: failure to retrieve a navmap object.
9403: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9404: calling routine should trap the error condition and display the warning
9405: found in &navmap_errormsg().
9406:
1.531 jms 9407: Returns the maximum number of bubble lines that are expected to
9408: occur. Does this by walking the selected sequence rendering the
9409: resource and then checking &Apache::lonxml::get_problem_counter()
9410: for what the current value of the problem counter is.
9411:
9412: Caches the results to $env{'form.scantron_maxbubble'},
9413: $env{'form.scantron.bubble_lines.n'},
9414: $env{'form.scantron.first_bubble_line.n'} and
9415: $env{"form.scantron.sub_bubblelines.n"}
9416: which are the total number of bubble, lines, the number of bubble
9417: lines for response n and number of the first bubble line for response n,
9418: and a comma separated list of numbers of bubble lines for sub-questions
9419: (for optionresponse, matchresponse, and rankresponse items), for response n.

9426: to be bubble free.
9427:
9428: =item scantron_process_students() :
9429:
9430: Routine that does the actual grading of the bubble sheet information.
9431:
9432: The parsed scanline hash is added to %env
9433:
9434: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9435: foreach resource , with the form data of
9436:
9437: 'submitted' =>'scantron'
9438: 'grade_target' =>'grade',
9439: 'grade_username'=> username of student
9440: 'grade_domain' => domain of student
9441: 'grade_courseid'=> of course
9442: 'grade_symb' => symb of resource to grade
9443:
9444: This triggers a grading pass. The problem grading code takes care
9445: of converting the bubbled letter information (now in %env) into a
9446: valid submission.
