4699: =head1 Bubble sheet grading routines
4700:
4701: For this documentation:
4702:
4703: 'scanline' refers to the full line of characters
4704: from the file that we are parsing that represents one entire sheet
4705:
4706: 'bubble line' refers to the data
4707: representing the line of bubbles that are on the physical bubble sheet
4708:
4709:
4710: The overall process is that a scanned in bubble sheet data is uploaded
4711: into a course. When a user wants to grade, they select a
4712: sequence/folder of resources, a file of bubble sheet info, and pick
4713: one of the predefined configurations for what each scanline looks
4714: like.
4715:
4716: Next each scanline is checked for any errors of either 'missing
4717: bubbles' (it's an error because it may have been mis-scanned
4718: because too light bubbling), 'double bubble' (each bubble line should
4719: have no more that one letter picked), invalid or duplicated CODE,
4720: invalid student/employee ID
4721:
4722: If the CODE option is used that determines the randomization of the
4723: homework problems, either way the student/employee ID is looked up into a
4724: username:domain.
4725:
4726: During the validation phase the instructor can choose to skip scanlines.
4727:
4728: After the validation phase, there are now 3 bubble sheet files
4729:
4730: scantron_original_filename (unmodified original file)
4731: scantron_corrected_filename (file where the corrected information has replaced the original information)
4732: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4733:
4734: Also there is a separate hash nohist_scantrondata that contains extra
4735: correction information that isn't representable in the bubble sheet
4736: file (see &scantron_getfile() for more information)
4737:
4738: After all scanlines are either valid, marked as valid or skipped, then
4739: foreach line foreach problem in the picked sequence, an ssi request is
4740: made that simulates a user submitting their selected letter(s) against
4741: the homework problem.

9223: =head1 NAME
9224:
9225: Apache::grades
9226:
9227: =head1 SYNOPSIS
9228:
9229: Handles the viewing of grades.
9230:
9231: This is part of the LearningOnline Network with CAPA project
9232: described at http://www.lon-capa.org.
9233:
9234: =head1 OVERVIEW
9235:
9236: Do an ssi with retries:
9237: While I'd love to factor out this with the vesrion in lonprintout,
9238: 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
9239: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9240:
9241: At least the logic that drives this has been pulled out into loncommon.
9242:
9243:
9244:
9245: ssi_with_retries - Does the server side include of a resource.
9246: if the ssi call returns an error we'll retry it up to
9247: the number of times requested by the caller.
9248: If we still have a proble, no text is appended to the
9249: output and we set some global variables.
9250: to indicate to the caller an SSI error occurred.
9251: All of this is supposed to deal with the issues described
9252: in LonCAPA BZ 5631 see:
9253: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9254: by informing the user that this happened.
9255:
9256: Parameters:
9257: resource - The resource to include. This is passed directly, without
9258: interpretation to lonnet::ssi.
9259: form - The form hash parameters that guide the interpretation of the resource
9260:
9261: retries - Number of retries allowed before giving up completely.
9262: Returns:
9263: On success, returns the rendered resource identified by the resource parameter.
9264: Side Effects:
9265: The following global variables can be set:
9266: ssi_error - If an unrecoverable error occurred this becomes true.
9267: It is up to the caller to initialize this to false
9268: if desired.
9269: ssi_error_resource - If an unrecoverable error occurred, this is the value
9270: of the resource that could not be rendered by the ssi
9271: call.
9272: ssi_error_message - The error string fetched from the ssi response
9273: in the event of an error.

9285:
9286: Builds the interface screen to interact with the operator to fix a
9287: specific error condition in a specific scanline
9288:
9289: Arguments:
9290: $r - Apache request object
9291: $i - number of the current scanline
9292: $scan_record - hash ref as returned from &scantron_parse_scanline()
9293: $scan_config - hash ref as returned from &get_scantron_config()
9294: $line - full contents of the current scanline
9295: $error - error condition, valid values are
9296: 'incorrectCODE', 'duplicateCODE',
9297: 'doublebubble', 'missingbubble',
9298: 'duplicateID', 'incorrectID'
9299: $arg - extra information needed
9300: For errors:
9301: - duplicateID - paper number that this studentID was seen before on
9302: - duplicateCODE - array ref of the paper numbers this CODE was
9303: seen on before
9304: - incorrectCODE - current incorrect CODE
9305: - doublebubble - array ref of the bubble lines that have double
9306: bubble errors
9307: - missingbubble - array ref of the bubble lines that have missing
9308: bubble errors
9309:
9310: =item scantron_get_maxbubble() :
9311:
9312: Returns the maximum number of bubble lines that are expected to
9313: occur. Does this by walking the selected sequence rendering the
9314: resource and then checking &Apache::lonxml::get_problem_counter()
9315: for what the current value of the problem counter is.
9316:
9317: Caches the results to $env{'form.scantron_maxbubble'},
9318: $env{'form.scantron.bubble_lines.n'},
9319: $env{'form.scantron.first_bubble_line.n'} and
9320: $env{"form.scantron.sub_bubblelines.n"}
9321: which are the total number of bubble, lines, the number of bubble
9322: lines for response n and number of the first bubble line for response n,
9323: and a comma separated list of numbers of bubble lines for sub-questions
9324: (for optionresponse, matchresponse, and rankresponse items), for response n.
9325:
9326:
9327: =item scantron_validate_missingbubbles() :
9328:
9329: Validates all scanlines in the selected file to not have any
9330: answers that don't have bubbles that have not been verified
9331: to be bubble free.
9332:
9333: =item scantron_process_students() :
9334:
9335: Routine that does the actual grading of the bubble sheet information.
9336:
9337: The parsed scanline hash is added to %env
9338:
9339: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9340: foreach resource , with the form data of
9341:
9342: 'submitted' =>'scantron'
9343: 'grade_target' =>'grade',
9344: 'grade_username'=> username of student
9345: 'grade_domain' => domain of student
9346: 'grade_courseid'=> of course
9347: 'grade_symb' => symb of resource to grade
9348:
9349: This triggers a grading pass. The problem grading code takes care
9350: of converting the bubbled letter information (now in %env) into a
9351: valid submission.
9352:
9353: =item scantron_upload_scantron_data() :
9354:
9355: Creates the screen for adding a new bubble sheet data file to a course.
9356:
9357: =item scantron_upload_scantron_data_save() :
9358:
9359: Adds a provided bubble information data file to the course if user
9360: has the correct privileges to do so.
9361:
9362: =item valid_file() :
9363:
9364: Validates that the requested bubble data file exists in the course.
9365:
9366: =item scantron_download_scantron_data() :
9367:
9368: Shows a list of the three internal files (original, corrected,
9369: skipped) for a specific bubble sheet data file that exists in the
9370: course.
9371:
9372: =item scantron_validate_ID() :
