4782: =head1 Bubble sheet grading routines
4783:
4784: For this documentation:
4785:
4786: 'scanline' refers to the full line of characters
4787: from the file that we are parsing that represents one entire sheet
4788:
4789: 'bubble line' refers to the data
4790: representing the line of bubbles that are on the physical bubble sheet
4791:
4792:
4793: The overall process is that a scanned in bubble sheet data is uploaded
4794: into a course. When a user wants to grade, they select a
4795: sequence/folder of resources, a file of bubble sheet info, and pick
4796: one of the predefined configurations for what each scanline looks
4797: like.
4798:
4799: Next each scanline is checked for any errors of either 'missing
4800: bubbles' (it's an error because it may have been mis-scanned
4801: because too light bubbling), 'double bubble' (each bubble line should
4802: have no more that one letter picked), invalid or duplicated CODE,
4803: invalid student/employee ID
4804:
4805: If the CODE option is used that determines the randomization of the
4806: homework problems, either way the student/employee ID is looked up into a
4807: username:domain.
4808:
4809: During the validation phase the instructor can choose to skip scanlines.
4810:
4811: After the validation phase, there are now 3 bubble sheet files
4812:
4813: scantron_original_filename (unmodified original file)
4814: scantron_corrected_filename (file where the corrected information has replaced the original information)
4815: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4816:
4817: Also there is a separate hash nohist_scantrondata that contains extra
4818: correction information that isn't representable in the bubble sheet
4819: file (see &scantron_getfile() for more information)
4820:
4821: After all scanlines are either valid, marked as valid or skipped, then
4822: foreach line foreach problem in the picked sequence, an ssi request is
4823: made that simulates a user submitting their selected letter(s) against
4824: the homework problem.

9395: =head1 NAME
9396:
9397: Apache::grades
9398:
9399: =head1 SYNOPSIS
9400:
9401: Handles the viewing of grades.
9402:
9403: This is part of the LearningOnline Network with CAPA project
9404: described at http://www.lon-capa.org.
9405:
9406: =head1 OVERVIEW
9407:
9408: Do an ssi with retries:
9409: While I'd love to factor out this with the vesrion in lonprintout,
9410: 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
9411: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9412:
9413: At least the logic that drives this has been pulled out into loncommon.
9414:
9415:
9416:
9417: ssi_with_retries - Does the server side include of a resource.
9418: if the ssi call returns an error we'll retry it up to
9419: the number of times requested by the caller.
9420: If we still have a proble, no text is appended to the
9421: output and we set some global variables.
9422: to indicate to the caller an SSI error occurred.
9423: All of this is supposed to deal with the issues described
9424: in LonCAPA BZ 5631 see:
9425: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9426: by informing the user that this happened.
9427:
9428: Parameters:
9429: resource - The resource to include. This is passed directly, without
9430: interpretation to lonnet::ssi.
9431: form - The form hash parameters that guide the interpretation of the resource
9432:
9433: retries - Number of retries allowed before giving up completely.
9434: Returns:
9435: On success, returns the rendered resource identified by the resource parameter.
9436: Side Effects:
9437: The following global variables can be set:
9438: ssi_error - If an unrecoverable error occurred this becomes true.
9439: It is up to the caller to initialize this to false
9440: if desired.
9441: ssi_error_resource - If an unrecoverable error occurred, this is the value
9442: of the resource that could not be rendered by the ssi
9443: call.
9444: ssi_error_message - The error string fetched from the ssi response
9445: in the event of an error.

9455:
9456: =item scantron_get_correction() :
9457:
9458: Builds the interface screen to interact with the operator to fix a
9459: specific error condition in a specific scanline
9460:
9461: Arguments:
9462: $r - Apache request object
9463: $i - number of the current scanline
9464: $scan_record - hash ref as returned from &scantron_parse_scanline()
9465: $scan_config - hash ref as returned from &get_scantron_config()
9466: $line - full contents of the current scanline
9467: $error - error condition, valid values are
9468: 'incorrectCODE', 'duplicateCODE',
9469: 'doublebubble', 'missingbubble',
9470: 'duplicateID', 'incorrectID'
9471: $arg - extra information needed
9472: For errors:
9473: - duplicateID - paper number that this studentID was seen before on
9474: - duplicateCODE - array ref of the paper numbers this CODE was
9475: seen on before
9476: - incorrectCODE - current incorrect CODE
9477: - doublebubble - array ref of the bubble lines that have double
9478: bubble errors
9479: - missingbubble - array ref of the bubble lines that have missing
9480: bubble errors
9481:
9482: =item scantron_get_maxbubble() :
9483:
9484: Arguments:
9485: $nav_error - Reference to scalar which is a flag to indicate a
9486: failure to retrieve a navmap object.
9487: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9488: calling routine should trap the error condition and display the warning
9489: found in &navmap_errormsg().
9490:
9491: Returns the maximum number of bubble lines that are expected to
9492: occur. Does this by walking the selected sequence rendering the
9493: resource and then checking &Apache::lonxml::get_problem_counter()
9494: for what the current value of the problem counter is.
9495:
9496: Caches the results to $env{'form.scantron_maxbubble'},
9497: $env{'form.scantron.bubble_lines.n'},
9498: $env{'form.scantron.first_bubble_line.n'} and
9499: $env{"form.scantron.sub_bubblelines.n"}
9500: which are the total number of bubble, lines, the number of bubble
9501: lines for response n and number of the first bubble line for response n,
9502: and a comma separated list of numbers of bubble lines for sub-questions
9503: (for optionresponse, matchresponse, and rankresponse items), for response n.
9504:
9505:
9506: =item scantron_validate_missingbubbles() :
9507:
9508: Validates all scanlines in the selected file to not have any
9509: answers that don't have bubbles that have not been verified
9510: to be bubble free.
9511:
9512: =item scantron_process_students() :
9513:
9514: Routine that does the actual grading of the bubble sheet information.
9515:
9516: The parsed scanline hash is added to %env
9517:
9518: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9519: foreach resource , with the form data of
9520:
9521: 'submitted' =>'scantron'
9522: 'grade_target' =>'grade',
9523: 'grade_username'=> username of student
9524: 'grade_domain' => domain of student
9525: 'grade_courseid'=> of course
9526: 'grade_symb' => symb of resource to grade
9527:
9528: This triggers a grading pass. The problem grading code takes care
9529: of converting the bubbled letter information (now in %env) into a
9530: valid submission.
9531:
9532: =item scantron_upload_scantron_data() :
9533:
9534: Creates the screen for adding a new bubble sheet data file to a course.
9535:
9536: =item scantron_upload_scantron_data_save() :
9537:
9538: Adds a provided bubble information data file to the course if user
9539: has the correct privileges to do so.
9540:
9541: =item valid_file() :
