4707: =head1 Bubble sheet grading routines
4708:
4709: For this documentation:
4710:
4711: 'scanline' refers to the full line of characters
4712: from the file that we are parsing that represents one entire sheet
4713:
4714: 'bubble line' refers to the data
4715: representing the line of bubbles that are on the physical bubble sheet
4716:
4717:
4718: The overall process is that a scanned in bubble sheet data is uploaded
4719: into a course. When a user wants to grade, they select a
4720: sequence/folder of resources, a file of bubble sheet info, and pick
4721: one of the predefined configurations for what each scanline looks
4722: like.
4723:
4724: Next each scanline is checked for any errors of either 'missing
4725: bubbles' (it's an error because it may have been mis-scanned
4726: because too light bubbling), 'double bubble' (each bubble line should
4727: have no more that one letter picked), invalid or duplicated CODE,
4728: invalid student/employee ID
4729:
4730: If the CODE option is used that determines the randomization of the
4731: homework problems, either way the student/employee ID is looked up into a
4732: username:domain.
4733:
4734: During the validation phase the instructor can choose to skip scanlines.
4735:
4736: After the validation phase, there are now 3 bubble sheet files
4737:
4738: scantron_original_filename (unmodified original file)
4739: scantron_corrected_filename (file where the corrected information has replaced the original information)
4740: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4741:
4742: Also there is a separate hash nohist_scantrondata that contains extra
4743: correction information that isn't representable in the bubble sheet
4744: file (see &scantron_getfile() for more information)
4745:
4746: After all scanlines are either valid, marked as valid or skipped, then
4747: foreach line foreach problem in the picked sequence, an ssi request is
4748: made that simulates a user submitting their selected letter(s) against
4749: the homework problem.

9231: =head1 NAME
9232:
9233: Apache::grades
9234:
9235: =head1 SYNOPSIS
9236:
9237: Handles the viewing of grades.
9238:
9239: This is part of the LearningOnline Network with CAPA project
9240: described at http://www.lon-capa.org.
9241:
9242: =head1 OVERVIEW
9243:
9244: Do an ssi with retries:
9245: While I'd love to factor out this with the vesrion in lonprintout,
9246: 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
9247: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9248:
9249: At least the logic that drives this has been pulled out into loncommon.
9250:
9251:
9252:
9253: ssi_with_retries - Does the server side include of a resource.
9254: if the ssi call returns an error we'll retry it up to
9255: the number of times requested by the caller.
9256: If we still have a proble, no text is appended to the
9257: output and we set some global variables.
9258: to indicate to the caller an SSI error occurred.
9259: All of this is supposed to deal with the issues described
9260: in LonCAPA BZ 5631 see:
9261: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9262: by informing the user that this happened.
9263:
9264: Parameters:
9265: resource - The resource to include. This is passed directly, without
9266: interpretation to lonnet::ssi.
9267: form - The form hash parameters that guide the interpretation of the resource
9268:
9269: retries - Number of retries allowed before giving up completely.
9270: Returns:
9271: On success, returns the rendered resource identified by the resource parameter.
9272: Side Effects:
9273: The following global variables can be set:
9274: ssi_error - If an unrecoverable error occurred this becomes true.
9275: It is up to the caller to initialize this to false
9276: if desired.
9277: ssi_error_resource - If an unrecoverable error occurred, this is the value
9278: of the resource that could not be rendered by the ssi
9279: call.
9280: ssi_error_message - The error string fetched from the ssi response
9281: in the event of an error.

9293:
9294: Builds the interface screen to interact with the operator to fix a
9295: specific error condition in a specific scanline
9296:
9297: Arguments:
9298: $r - Apache request object
9299: $i - number of the current scanline
9300: $scan_record - hash ref as returned from &scantron_parse_scanline()
9301: $scan_config - hash ref as returned from &get_scantron_config()
9302: $line - full contents of the current scanline
9303: $error - error condition, valid values are
9304: 'incorrectCODE', 'duplicateCODE',
9305: 'doublebubble', 'missingbubble',
9306: 'duplicateID', 'incorrectID'
9307: $arg - extra information needed
9308: For errors:
9309: - duplicateID - paper number that this studentID was seen before on
9310: - duplicateCODE - array ref of the paper numbers this CODE was
9311: seen on before
9312: - incorrectCODE - current incorrect CODE
9313: - doublebubble - array ref of the bubble lines that have double
9314: bubble errors
9315: - missingbubble - array ref of the bubble lines that have missing
9316: bubble errors
9317:
9318: =item scantron_get_maxbubble() :
9319:
9320: Returns the maximum number of bubble lines that are expected to
9321: occur. Does this by walking the selected sequence rendering the
9322: resource and then checking &Apache::lonxml::get_problem_counter()
9323: for what the current value of the problem counter is.
9324:
9325: Caches the results to $env{'form.scantron_maxbubble'},
9326: $env{'form.scantron.bubble_lines.n'},
9327: $env{'form.scantron.first_bubble_line.n'} and
9328: $env{"form.scantron.sub_bubblelines.n"}
9329: which are the total number of bubble, lines, the number of bubble
9330: lines for response n and number of the first bubble line for response n,
9331: and a comma separated list of numbers of bubble lines for sub-questions
9332: (for optionresponse, matchresponse, and rankresponse items), for response n.
9333:
9334:
9335: =item scantron_validate_missingbubbles() :
9336:
9337: Validates all scanlines in the selected file to not have any
9338: answers that don't have bubbles that have not been verified
9339: to be bubble free.
9340:
9341: =item scantron_process_students() :
9342:
9343: Routine that does the actual grading of the bubble sheet information.
9344:
9345: The parsed scanline hash is added to %env
9346:
9347: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9348: foreach resource , with the form data of
9349:
9350: 'submitted' =>'scantron'
9351: 'grade_target' =>'grade',
9352: 'grade_username'=> username of student
9353: 'grade_domain' => domain of student
9354: 'grade_courseid'=> of course
9355: 'grade_symb' => symb of resource to grade
9356:
9357: This triggers a grading pass. The problem grading code takes care
9358: of converting the bubbled letter information (now in %env) into a
9359: valid submission.
9360:
9361: =item scantron_upload_scantron_data() :
9362:
9363: Creates the screen for adding a new bubble sheet data file to a course.
9364:
9365: =item scantron_upload_scantron_data_save() :
9366:
9367: Adds a provided bubble information data file to the course if user
9368: has the correct privileges to do so.
9369:
9370: =item valid_file() :
9371:
9372: Validates that the requested bubble data file exists in the course.
9373:
9374: =item scantron_download_scantron_data() :
9375:
9376: Shows a list of the three internal files (original, corrected,
9377: skipped) for a specific bubble sheet data file that exists in the
9378: course.
9379:
9380: =item scantron_validate_ID() :
