4757: =head1 Bubble sheet grading routines
4758:
4759: For this documentation:
4760:
4761: 'scanline' refers to the full line of characters
4762: from the file that we are parsing that represents one entire sheet
4763:
4764: 'bubble line' refers to the data
4765: representing the line of bubbles that are on the physical bubble sheet
4766:
4767:
4768: The overall process is that a scanned in bubble sheet data is uploaded
4769: into a course. When a user wants to grade, they select a
4770: sequence/folder of resources, a file of bubble sheet info, and pick
4771: one of the predefined configurations for what each scanline looks
4772: like.
4773:
4774: Next each scanline is checked for any errors of either 'missing
4775: bubbles' (it's an error because it may have been mis-scanned
4776: because too light bubbling), 'double bubble' (each bubble line should
4777: have no more that one letter picked), invalid or duplicated CODE,
4778: invalid student/employee ID
4779:
4780: If the CODE option is used that determines the randomization of the
4781: homework problems, either way the student/employee ID is looked up into a
4782: username:domain.
4783:
4784: During the validation phase the instructor can choose to skip scanlines.
4785:
4786: After the validation phase, there are now 3 bubble sheet files
4787:
4788: scantron_original_filename (unmodified original file)
4789: scantron_corrected_filename (file where the corrected information has replaced the original information)
4790: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4791:
4792: Also there is a separate hash nohist_scantrondata that contains extra
4793: correction information that isn't representable in the bubble sheet
4794: file (see &scantron_getfile() for more information)
4795:
4796: After all scanlines are either valid, marked as valid or skipped, then
4797: foreach line foreach problem in the picked sequence, an ssi request is
4798: made that simulates a user submitting their selected letter(s) against
4799: the homework problem.

9314: =head1 NAME
9315:
9316: Apache::grades
9317:
9318: =head1 SYNOPSIS
9319:
9320: Handles the viewing of grades.
9321:
9322: This is part of the LearningOnline Network with CAPA project
9323: described at http://www.lon-capa.org.
9324:
9325: =head1 OVERVIEW
9326:
9327: Do an ssi with retries:
9328: While I'd love to factor out this with the vesrion in lonprintout,
9329: 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
9330: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9331:
9332: At least the logic that drives this has been pulled out into loncommon.
9333:
9334:
9335:
9336: ssi_with_retries - Does the server side include of a resource.
9337: if the ssi call returns an error we'll retry it up to
9338: the number of times requested by the caller.
9339: If we still have a proble, no text is appended to the
9340: output and we set some global variables.
9341: to indicate to the caller an SSI error occurred.
9342: All of this is supposed to deal with the issues described
9343: in LonCAPA BZ 5631 see:
9344: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9345: by informing the user that this happened.
9346:
9347: Parameters:
9348: resource - The resource to include. This is passed directly, without
9349: interpretation to lonnet::ssi.
9350: form - The form hash parameters that guide the interpretation of the resource
9351:
9352: retries - Number of retries allowed before giving up completely.
9353: Returns:
9354: On success, returns the rendered resource identified by the resource parameter.
9355: Side Effects:
9356: The following global variables can be set:
9357: ssi_error - If an unrecoverable error occurred this becomes true.
9358: It is up to the caller to initialize this to false
9359: if desired.
9360: ssi_error_resource - If an unrecoverable error occurred, this is the value
9361: of the resource that could not be rendered by the ssi
9362: call.
9363: ssi_error_message - The error string fetched from the ssi response
9364: in the event of an error.

9375: =item scantron_get_correction() :
9376:
9377: Builds the interface screen to interact with the operator to fix a
9378: specific error condition in a specific scanline
9379:
9380: Arguments:
9381: $r - Apache request object
9382: $i - number of the current scanline
9383: $scan_record - hash ref as returned from &scantron_parse_scanline()
9384: $scan_config - hash ref as returned from &get_scantron_config()
9385: $line - full contents of the current scanline
9386: $error - error condition, valid values are
9387: 'incorrectCODE', 'duplicateCODE',
9388: 'doublebubble', 'missingbubble',
9389: 'duplicateID', 'incorrectID'
9390: $arg - extra information needed
9391: For errors:
9392: - duplicateID - paper number that this studentID was seen before on
9393: - duplicateCODE - array ref of the paper numbers this CODE was
9394: seen on before
9395: - incorrectCODE - current incorrect CODE
9396: - doublebubble - array ref of the bubble lines that have double
9397: bubble errors
9398: - missingbubble - array ref of the bubble lines that have missing
9399: bubble errors
9400:
9401: =item scantron_get_maxbubble() :
9402:
9403: Arguments:
9404: $nav_error - Reference to scalar which is a flag to indicate a
9405: failure to retrieve a navmap object.
9406: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9407: calling routine should trap the error condition and display the warning
9408: found in &navmap_errormsg().
9409:
9410: Returns the maximum number of bubble lines that are expected to
9411: occur. Does this by walking the selected sequence rendering the
9412: resource and then checking &Apache::lonxml::get_problem_counter()
9413: for what the current value of the problem counter is.
9414:
9415: Caches the results to $env{'form.scantron_maxbubble'},
9416: $env{'form.scantron.bubble_lines.n'},
9417: $env{'form.scantron.first_bubble_line.n'} and
9418: $env{"form.scantron.sub_bubblelines.n"}
9419: which are the total number of bubble, lines, the number of bubble
9420: lines for response n and number of the first bubble line for response n,
9421: and a comma separated list of numbers of bubble lines for sub-questions
9422: (for optionresponse, matchresponse, and rankresponse items), for response n.
9423:
9424:
9425: =item scantron_validate_missingbubbles() :
9426:
9427: Validates all scanlines in the selected file to not have any
9428: answers that don't have bubbles that have not been verified
9429: to be bubble free.
9430:
9431: =item scantron_process_students() :
9432:
9433: Routine that does the actual grading of the bubble sheet information.
9434:
9435: The parsed scanline hash is added to %env
9436:
9437: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9438: foreach resource , with the form data of
9439:
9440: 'submitted' =>'scantron'
9441: 'grade_target' =>'grade',
9442: 'grade_username'=> username of student
9443: 'grade_domain' => domain of student
9444: 'grade_courseid'=> of course
9445: 'grade_symb' => symb of resource to grade
9446:
9447: This triggers a grading pass. The problem grading code takes care
9448: of converting the bubbled letter information (now in %env) into a
9449: valid submission.
9450:
9451: =item scantron_upload_scantron_data() :
9452:
9453: Creates the screen for adding a new bubble sheet data file to a course.
9454:
9455: =item scantron_upload_scantron_data_save() :
9456:
9457: Adds a provided bubble information data file to the course if user
9458: has the correct privileges to do so.
9459:
9460: =item valid_file() :
9461:
9462: Validates that the requested bubble data file exists in the course.
9463:
9464: =item scantron_download_scantron_data() :
9465:
9466: Shows a list of the three internal files (original, corrected,
9467: skipped) for a specific bubble sheet data file that exists in the
9468: course.
9469:
9470: =item scantron_validate_ID() :
9471:
9472: Validates all scanlines in the selected file to not have any
9473: invalid or underspecified student/employee IDs
9474:
9475: =item navmap_errormsg() :
9476:
9477: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9478: Should be called whenever the request to instantiate a navmap object fails.
