4698:
1.424 albertel 4699: For this documentation:
4700:
4701: 'scanline' refers to the full line of characters
4702: from the file that we are parsing that represents one entire sheet
4703:
4704: 'bubble line' refers to the data
4705: representing the line of bubbles that are on the physical bubble sheet
4706:
4707:
4708: The overall process is that a scanned in bubble sheet data is uploaded
4709: into a course. When a user wants to grade, they select a
4710: sequence/folder of resources, a file of bubble sheet info, and pick
4711: one of the predefined configurations for what each scanline looks
4712: like.
4713:
4714: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4715: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4716: because too light bubbling), 'double bubble' (each bubble line should
4717: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4718: invalid student/employee ID
1.424 albertel 4719:
4720: If the CODE option is used that determines the randomization of the
1.556 weissno 4721: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4722: username:domain.
4723:
4724: During the validation phase the instructor can choose to skip scanlines.
4725:
1.435 foxr 4726: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4727:
4728: scantron_original_filename (unmodified original file)
4729: scantron_corrected_filename (file where the corrected information has replaced the original information)
4730: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4731:
4732: Also there is a separate hash nohist_scantrondata that contains extra
4733: correction information that isn't representable in the bubble sheet
4734: file (see &scantron_getfile() for more information)
4735:
4736: After all scanlines are either valid, marked as valid or skipped, then
4737: foreach line foreach problem in the picked sequence, an ssi request is
4738: made that simulates a user submitting their selected letter(s) against
4739: the homework problem.

9229: =head1 NAME
9230:
9231: Apache::grades
9232:
9233: =head1 SYNOPSIS
9234:
9235: Handles the viewing of grades.
9236:
9237: This is part of the LearningOnline Network with CAPA project
9238: described at http://www.lon-capa.org.
9239:
9240: =head1 OVERVIEW
9241:
9242: Do an ssi with retries:
9243: While I'd love to factor out this with the vesrion in lonprintout,
9244: 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
9245: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9246:
9247: At least the logic that drives this has been pulled out into loncommon.
9248:
9249:
9250:
9251: ssi_with_retries - Does the server side include of a resource.
9252: if the ssi call returns an error we'll retry it up to
9253: the number of times requested by the caller.
9254: If we still have a proble, no text is appended to the
9255: output and we set some global variables.
9256: to indicate to the caller an SSI error occurred.
9257: All of this is supposed to deal with the issues described
9258: in LonCAPA BZ 5631 see:
9259: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9260: by informing the user that this happened.
9261:
9262: Parameters:
9263: resource - The resource to include. This is passed directly, without
9264: interpretation to lonnet::ssi.
9265: form - The form hash parameters that guide the interpretation of the resource
9266:
9267: retries - Number of retries allowed before giving up completely.
9268: Returns:
9269: On success, returns the rendered resource identified by the resource parameter.
9270: Side Effects:
9271: The following global variables can be set:
9272: ssi_error - If an unrecoverable error occurred this becomes true.
9273: It is up to the caller to initialize this to false
9274: if desired.
9275: ssi_error_resource - If an unrecoverable error occurred, this is the value
9276: of the resource that could not be rendered by the ssi
9277: call.
9278: ssi_error_message - The error string fetched from the ssi response
9279: in the event of an error.

9289:
9290: =item scantron_get_correction() :
9291:
9292: Builds the interface screen to interact with the operator to fix a
9293: specific error condition in a specific scanline
9294:
9295: Arguments:
9296: $r - Apache request object
9297: $i - number of the current scanline
9298: $scan_record - hash ref as returned from &scantron_parse_scanline()
9299: $scan_config - hash ref as returned from &get_scantron_config()
9300: $line - full contents of the current scanline
9301: $error - error condition, valid values are
9302: 'incorrectCODE', 'duplicateCODE',
9303: 'doublebubble', 'missingbubble',
9304: 'duplicateID', 'incorrectID'
9305: $arg - extra information needed
9306: For errors:
9307: - duplicateID - paper number that this studentID was seen before on
9308: - duplicateCODE - array ref of the paper numbers this CODE was
9309: seen on before
9310: - incorrectCODE - current incorrect CODE
9311: - doublebubble - array ref of the bubble lines that have double
9312: bubble errors
9313: - missingbubble - array ref of the bubble lines that have missing
9314: bubble errors
9315:
9316: =item scantron_get_maxbubble() :
9317:
9318: Returns the maximum number of bubble lines that are expected to
9319: occur. Does this by walking the selected sequence rendering the
9320: resource and then checking &Apache::lonxml::get_problem_counter()
9321: for what the current value of the problem counter is.
9322:
9323: Caches the results to $env{'form.scantron_maxbubble'},
9324: $env{'form.scantron.bubble_lines.n'},
9325: $env{'form.scantron.first_bubble_line.n'} and
9326: $env{"form.scantron.sub_bubblelines.n"}
9327: which are the total number of bubble, lines, the number of bubble
9328: lines for response n and number of the first bubble line for response n,
9329: and a comma separated list of numbers of bubble lines for sub-questions
9330: (for optionresponse, matchresponse, and rankresponse items), for response n.
9331:
9332:
9333: =item scantron_validate_missingbubbles() :
9334:
9335: Validates all scanlines in the selected file to not have any
9336: answers that don't have bubbles that have not been verified
9337: to be bubble free.
9338:
9339: =item scantron_process_students() :
9340:
9341: Routine that does the actual grading of the bubble sheet information.
9342:
9343: The parsed scanline hash is added to %env
9344:
9345: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9346: foreach resource , with the form data of
9347:
9348: 'submitted' =>'scantron'
9349: 'grade_target' =>'grade',
9350: 'grade_username'=> username of student
9351: 'grade_domain' => domain of student
9352: 'grade_courseid'=> of course
9353: 'grade_symb' => symb of resource to grade
9354:
9355: This triggers a grading pass. The problem grading code takes care
9356: of converting the bubbled letter information (now in %env) into a
9357: valid submission.
9358:
9359: =item scantron_upload_scantron_data() :
9360:
9361: Creates the screen for adding a new bubble sheet data file to a course.
9362:
9363: =item scantron_upload_scantron_data_save() :
9364:
9365: Adds a provided bubble information data file to the course if user
9366: has the correct privileges to do so.
9367:
9368: =item valid_file() :
9369:
9370: Validates that the requested bubble data file exists in the course.
9371:
9372: =item scantron_download_scantron_data() :
9373:
9374: Shows a list of the three internal files (original, corrected,
9375: skipped) for a specific bubble sheet data file that exists in the
9376: course.
9377:
9378: =item scantron_validate_ID() :
9379:
9380: Validates all scanlines in the selected file to not have any
1.556 weissno 9381: invalid or underspecified student/employee IDs
