4766: =head1 Bubble sheet grading routines
4767:
4768: For this documentation:
4769:
4770: 'scanline' refers to the full line of characters
4771: from the file that we are parsing that represents one entire sheet
4772:
4773: 'bubble line' refers to the data
4774: representing the line of bubbles that are on the physical bubble sheet
4775:
4776:
4777: The overall process is that a scanned in bubble sheet data is uploaded
4778: into a course. When a user wants to grade, they select a
4779: sequence/folder of resources, a file of bubble sheet info, and pick
4780: one of the predefined configurations for what each scanline looks
4781: like.
4782:
4783: Next each scanline is checked for any errors of either 'missing
4784: bubbles' (it's an error because it may have been mis-scanned
4785: because too light bubbling), 'double bubble' (each bubble line should
4786: have no more that one letter picked), invalid or duplicated CODE,
4787: invalid student/employee ID
4788:
4789: If the CODE option is used that determines the randomization of the
4790: homework problems, either way the student/employee ID is looked up into a
4791: username:domain.
4792:
4793: During the validation phase the instructor can choose to skip scanlines.
4794:
4795: After the validation phase, there are now 3 bubble sheet files
4796:
4797: scantron_original_filename (unmodified original file)
4798: scantron_corrected_filename (file where the corrected information has replaced the original information)
4799: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4800:
4801: Also there is a separate hash nohist_scantrondata that contains extra
4802: correction information that isn't representable in the bubble sheet
4803: file (see &scantron_getfile() for more information)
4804:
4805: After all scanlines are either valid, marked as valid or skipped, then
4806: foreach line foreach problem in the picked sequence, an ssi request is
4807: made that simulates a user submitting their selected letter(s) against
4808: the homework problem.

9329: =head1 NAME
9330:
9331: Apache::grades
9332:
9333: =head1 SYNOPSIS
9334:
9335: Handles the viewing of grades.
9336:
9337: This is part of the LearningOnline Network with CAPA project
9338: described at http://www.lon-capa.org.
9339:
9340: =head1 OVERVIEW
9341:
9342: Do an ssi with retries:
9343: While I'd love to factor out this with the vesrion in lonprintout,
9344: 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
9345: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9346:
9347: At least the logic that drives this has been pulled out into loncommon.
9348:
9349:
9350:
9351: ssi_with_retries - Does the server side include of a resource.
9352: if the ssi call returns an error we'll retry it up to
9353: the number of times requested by the caller.
9354: If we still have a proble, no text is appended to the
9355: output and we set some global variables.
9356: to indicate to the caller an SSI error occurred.
9357: All of this is supposed to deal with the issues described
9358: in LonCAPA BZ 5631 see:
9359: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9360: by informing the user that this happened.
9361:
9362: Parameters:
9363: resource - The resource to include. This is passed directly, without
9364: interpretation to lonnet::ssi.
9365: form - The form hash parameters that guide the interpretation of the resource
9366:
9367: retries - Number of retries allowed before giving up completely.
9368: Returns:
9369: On success, returns the rendered resource identified by the resource parameter.
9370: Side Effects:
9371: The following global variables can be set:
9372: ssi_error - If an unrecoverable error occurred this becomes true.
9373: It is up to the caller to initialize this to false
9374: if desired.
9375: ssi_error_resource - If an unrecoverable error occurred, this is the value
9376: of the resource that could not be rendered by the ssi
9377: call.
9378: ssi_error_message - The error string fetched from the ssi response
9379: in the event of an error.

9389:
9390: =item scantron_get_correction() :
9391:
9392: Builds the interface screen to interact with the operator to fix a
9393: specific error condition in a specific scanline
9394:
9395: Arguments:
9396: $r - Apache request object
9397: $i - number of the current scanline
9398: $scan_record - hash ref as returned from &scantron_parse_scanline()
9399: $scan_config - hash ref as returned from &get_scantron_config()
9400: $line - full contents of the current scanline
9401: $error - error condition, valid values are
9402: 'incorrectCODE', 'duplicateCODE',
9403: 'doublebubble', 'missingbubble',
9404: 'duplicateID', 'incorrectID'
9405: $arg - extra information needed
9406: For errors:
9407: - duplicateID - paper number that this studentID was seen before on
9408: - duplicateCODE - array ref of the paper numbers this CODE was
9409: seen on before
9410: - incorrectCODE - current incorrect CODE
9411: - doublebubble - array ref of the bubble lines that have double
9412: bubble errors
9413: - missingbubble - array ref of the bubble lines that have missing
9414: bubble errors
9415:
9416: =item scantron_get_maxbubble() :
9417:
9418: Arguments:
9419: $nav_error - Reference to scalar which is a flag to indicate a
9420: failure to retrieve a navmap object.
9421: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9422: calling routine should trap the error condition and display the warning
9423: found in &navmap_errormsg().
9424:
9425: Returns the maximum number of bubble lines that are expected to
9426: occur. Does this by walking the selected sequence rendering the
9427: resource and then checking &Apache::lonxml::get_problem_counter()
9428: for what the current value of the problem counter is.
9429:
9430: Caches the results to $env{'form.scantron_maxbubble'},
9431: $env{'form.scantron.bubble_lines.n'},
9432: $env{'form.scantron.first_bubble_line.n'} and
9433: $env{"form.scantron.sub_bubblelines.n"}
9434: which are the total number of bubble, lines, the number of bubble
9435: lines for response n and number of the first bubble line for response n,
9436: and a comma separated list of numbers of bubble lines for sub-questions
9437: (for optionresponse, matchresponse, and rankresponse items), for response n.
9438:
9439:
9440: =item scantron_validate_missingbubbles() :
9441:
9442: Validates all scanlines in the selected file to not have any
9443: answers that don't have bubbles that have not been verified
9444: to be bubble free.
9445:
9446: =item scantron_process_students() :
9447:
9448: Routine that does the actual grading of the bubble sheet information.
9449:
9450: The parsed scanline hash is added to %env
9451:
9452: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9453: foreach resource , with the form data of
9454:
9455: 'submitted' =>'scantron'
9456: 'grade_target' =>'grade',
9457: 'grade_username'=> username of student
9458: 'grade_domain' => domain of student
9459: 'grade_courseid'=> of course
9460: 'grade_symb' => symb of resource to grade
9461:
9462: This triggers a grading pass. The problem grading code takes care
9463: of converting the bubbled letter information (now in %env) into a
9464: valid submission.
9465:
9466: =item scantron_upload_scantron_data() :
9467:
9468: Creates the screen for adding a new bubble sheet data file to a course.
9469:
9470: =item scantron_upload_scantron_data_save() :
9471:
9472: Adds a provided bubble information data file to the course if user
9473: has the correct privileges to do so.
9474:
9475: =item valid_file() :
9476:
9477: Validates that the requested bubble data file exists in the course.
9478:
9479: =item scantron_download_scantron_data() :
9480:
9481: Shows a list of the three internal files (original, corrected,
9482: skipped) for a specific bubble sheet data file that exists in the
9483: course.
9484:
9485: =item scantron_validate_ID() :
9486:
9487: Validates all scanlines in the selected file to not have any
9488: invalid or underspecified student/employee IDs
9489:
9490: =item navmap_errormsg() :
9491:
9492: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9493: Should be called whenever the request to instantiate a navmap object fails.
