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

9228: =head1 NAME
9229:
9230: Apache::grades
9231:
9232: =head1 SYNOPSIS
9233:
9234: Handles the viewing of grades.
9235:
9236: This is part of the LearningOnline Network with CAPA project
9237: described at http://www.lon-capa.org.
9238:
9239: =head1 OVERVIEW
9240:
9241: Do an ssi with retries:
9242: While I'd love to factor out this with the vesrion in lonprintout,
9243: 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
9244: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9245:
9246: At least the logic that drives this has been pulled out into loncommon.
9247:
9248:
9249:
9250: ssi_with_retries - Does the server side include of a resource.
9251: if the ssi call returns an error we'll retry it up to
9252: the number of times requested by the caller.
9253: If we still have a proble, no text is appended to the
9254: output and we set some global variables.
9255: to indicate to the caller an SSI error occurred.
9256: All of this is supposed to deal with the issues described
9257: in LonCAPA BZ 5631 see:
9258: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9259: by informing the user that this happened.
9260:
9261: Parameters:
9262: resource - The resource to include. This is passed directly, without
9263: interpretation to lonnet::ssi.
9264: form - The form hash parameters that guide the interpretation of the resource
9265:
9266: retries - Number of retries allowed before giving up completely.
9267: Returns:
9268: On success, returns the rendered resource identified by the resource parameter.
9269: Side Effects:
9270: The following global variables can be set:
9271: ssi_error - If an unrecoverable error occurred this becomes true.
9272: It is up to the caller to initialize this to false
9273: if desired.
9274: ssi_error_resource - If an unrecoverable error occurred, this is the value
9275: of the resource that could not be rendered by the ssi
9276: call.
9277: ssi_error_message - The error string fetched from the ssi response
9278: in the event of an error.

9289: =item scantron_get_correction() :
9290:
9291: Builds the interface screen to interact with the operator to fix a
9292: specific error condition in a specific scanline
9293:
9294: Arguments:
9295: $r - Apache request object
9296: $i - number of the current scanline
9297: $scan_record - hash ref as returned from &scantron_parse_scanline()
9298: $scan_config - hash ref as returned from &get_scantron_config()
9299: $line - full contents of the current scanline
9300: $error - error condition, valid values are
9301: 'incorrectCODE', 'duplicateCODE',
9302: 'doublebubble', 'missingbubble',
9303: 'duplicateID', 'incorrectID'
9304: $arg - extra information needed
9305: For errors:
9306: - duplicateID - paper number that this studentID was seen before on
9307: - duplicateCODE - array ref of the paper numbers this CODE was
9308: seen on before
9309: - incorrectCODE - current incorrect CODE
9310: - doublebubble - array ref of the bubble lines that have double
9311: bubble errors
9312: - missingbubble - array ref of the bubble lines that have missing
9313: bubble errors
9314:
9315: =item scantron_get_maxbubble() :
9316:
9317: Returns the maximum number of bubble lines that are expected to
9318: occur. Does this by walking the selected sequence rendering the
9319: resource and then checking &Apache::lonxml::get_problem_counter()
9320: for what the current value of the problem counter is.
9321:
9322: Caches the results to $env{'form.scantron_maxbubble'},
9323: $env{'form.scantron.bubble_lines.n'},
9324: $env{'form.scantron.first_bubble_line.n'} and
9325: $env{"form.scantron.sub_bubblelines.n"}
9326: which are the total number of bubble, lines, the number of bubble
9327: lines for response n and number of the first bubble line for response n,
9328: and a comma separated list of numbers of bubble lines for sub-questions
9329: (for optionresponse, matchresponse, and rankresponse items), for response n.
9330:
9331:
9332: =item scantron_validate_missingbubbles() :
9333:
9334: Validates all scanlines in the selected file to not have any
9335: answers that don't have bubbles that have not been verified
9336: to be bubble free.
9337:
9338: =item scantron_process_students() :
9339:
9340: Routine that does the actual grading of the bubble sheet information.
9341:
9342: The parsed scanline hash is added to %env
9343:
9344: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9345: foreach resource , with the form data of
9346:
9347: 'submitted' =>'scantron'
9348: 'grade_target' =>'grade',
9349: 'grade_username'=> username of student
9350: 'grade_domain' => domain of student
9351: 'grade_courseid'=> of course
9352: 'grade_symb' => symb of resource to grade
9353:
9354: This triggers a grading pass. The problem grading code takes care
9355: of converting the bubbled letter information (now in %env) into a
9356: valid submission.
9357:
9358: =item scantron_upload_scantron_data() :
9359:
9360: Creates the screen for adding a new bubble sheet data file to a course.
9361:
9362: =item scantron_upload_scantron_data_save() :
9363:
9364: Adds a provided bubble information data file to the course if user
9365: has the correct privileges to do so.
9366:
9367: =item valid_file() :
9368:
9369: Validates that the requested bubble data file exists in the course.
9370:
9371: =item scantron_download_scantron_data() :
9372:
9373: Shows a list of the three internal files (original, corrected,
9374: skipped) for a specific bubble sheet data file that exists in the
9375: course.
9376:
9377: =item scantron_validate_ID() :
9378:
9379: Validates all scanlines in the selected file to not have any
1.556 weissno 9380: invalid or underspecified student/employee IDs
