4789:
1.424 albertel 4790: For this documentation:
4791:
4792: 'scanline' refers to the full line of characters
4793: from the file that we are parsing that represents one entire sheet
4794:
4795: 'bubble line' refers to the data
4796: representing the line of bubbles that are on the physical bubble sheet
4797:
4798:
4799: The overall process is that a scanned in bubble sheet data is uploaded
4800: into a course. When a user wants to grade, they select a
4801: sequence/folder of resources, a file of bubble sheet info, and pick
4802: one of the predefined configurations for what each scanline looks
4803: like.
4804:
4805: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4806: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4807: because too light bubbling), 'double bubble' (each bubble line should
4808: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4809: invalid student/employee ID
1.424 albertel 4810:
4811: If the CODE option is used that determines the randomization of the
1.556 weissno 4812: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4813: username:domain.
4814:
4815: During the validation phase the instructor can choose to skip scanlines.
4816:
1.435 foxr 4817: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4818:
4819: scantron_original_filename (unmodified original file)
4820: scantron_corrected_filename (file where the corrected information has replaced the original information)
4821: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4822:
4823: Also there is a separate hash nohist_scantrondata that contains extra
4824: correction information that isn't representable in the bubble sheet
4825: file (see &scantron_getfile() for more information)
4826:
4827: After all scanlines are either valid, marked as valid or skipped, then
4828: foreach line foreach problem in the picked sequence, an ssi request is
4829: made that simulates a user submitting their selected letter(s) against
4830: the homework problem.

9360: =head1 NAME
9361:
9362: Apache::grades
9363:
9364: =head1 SYNOPSIS
9365:
9366: Handles the viewing of grades.
9367:
9368: This is part of the LearningOnline Network with CAPA project
9369: described at http://www.lon-capa.org.
9370:
9371: =head1 OVERVIEW
9372:
9373: Do an ssi with retries:
9374: While I'd love to factor out this with the vesrion in lonprintout,
9375: 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
9376: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9377:
9378: At least the logic that drives this has been pulled out into loncommon.
9379:
9380:
9381:
9382: ssi_with_retries - Does the server side include of a resource.
9383: if the ssi call returns an error we'll retry it up to
9384: the number of times requested by the caller.
9385: If we still have a proble, no text is appended to the
9386: output and we set some global variables.
9387: to indicate to the caller an SSI error occurred.
9388: All of this is supposed to deal with the issues described
9389: in LonCAPA BZ 5631 see:
9390: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9391: by informing the user that this happened.
9392:
9393: Parameters:
9394: resource - The resource to include. This is passed directly, without
9395: interpretation to lonnet::ssi.
9396: form - The form hash parameters that guide the interpretation of the resource
9397:
9398: retries - Number of retries allowed before giving up completely.
9399: Returns:
9400: On success, returns the rendered resource identified by the resource parameter.
9401: Side Effects:
9402: The following global variables can be set:
9403: ssi_error - If an unrecoverable error occurred this becomes true.
9404: It is up to the caller to initialize this to false
9405: if desired.
9406: ssi_error_resource - If an unrecoverable error occurred, this is the value
9407: of the resource that could not be rendered by the ssi
9408: call.
9409: ssi_error_message - The error string fetched from the ssi response
9410: in the event of an error.

9420:
9421: =item scantron_get_correction() :
9422:
9423: Builds the interface screen to interact with the operator to fix a
9424: specific error condition in a specific scanline
9425:
9426: Arguments:
9427: $r - Apache request object
9428: $i - number of the current scanline
9429: $scan_record - hash ref as returned from &scantron_parse_scanline()
9430: $scan_config - hash ref as returned from &get_scantron_config()
9431: $line - full contents of the current scanline
9432: $error - error condition, valid values are
9433: 'incorrectCODE', 'duplicateCODE',
9434: 'doublebubble', 'missingbubble',
9435: 'duplicateID', 'incorrectID'
9436: $arg - extra information needed
9437: For errors:
9438: - duplicateID - paper number that this studentID was seen before on
9439: - duplicateCODE - array ref of the paper numbers this CODE was
9440: seen on before
9441: - incorrectCODE - current incorrect CODE
9442: - doublebubble - array ref of the bubble lines that have double
9443: bubble errors
9444: - missingbubble - array ref of the bubble lines that have missing
9445: bubble errors
9446:
9447: =item scantron_get_maxbubble() :
9448:
1.582 raeburn 9449: Arguments:
9450: $nav_error - Reference to scalar which is a flag to indicate a
9451: failure to retrieve a navmap object.
9452: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9453: calling routine should trap the error condition and display the warning
9454: found in &navmap_errormsg().
9455:
1.531 jms 9456: Returns the maximum number of bubble lines that are expected to
9457: occur. Does this by walking the selected sequence rendering the
9458: resource and then checking &Apache::lonxml::get_problem_counter()
9459: for what the current value of the problem counter is.
9460:
9461: Caches the results to $env{'form.scantron_maxbubble'},
9462: $env{'form.scantron.bubble_lines.n'},
9463: $env{'form.scantron.first_bubble_line.n'} and
9464: $env{"form.scantron.sub_bubblelines.n"}
9465: which are the total number of bubble, lines, the number of bubble
9466: lines for response n and number of the first bubble line for response n,
9467: and a comma separated list of numbers of bubble lines for sub-questions
9468: (for optionresponse, matchresponse, and rankresponse items), for response n.
9469:
9470:
9471: =item scantron_validate_missingbubbles() :
9472:
9473: Validates all scanlines in the selected file to not have any
9474: answers that don't have bubbles that have not been verified
9475: to be bubble free.
9476:
9477: =item scantron_process_students() :
9478:
9479: Routine that does the actual grading of the bubble sheet information.
9480:
9481: The parsed scanline hash is added to %env
9482:
9483: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9484: foreach resource , with the form data of
9485:
9486: 'submitted' =>'scantron'
9487: 'grade_target' =>'grade',
9488: 'grade_username'=> username of student
9489: 'grade_domain' => domain of student
9490: 'grade_courseid'=> of course
9491: 'grade_symb' => symb of resource to grade
9492:
9493: This triggers a grading pass. The problem grading code takes care
9494: of converting the bubbled letter information (now in %env) into a
9495: valid submission.
9496:
9497: =item scantron_upload_scantron_data() :
9498:
9499: Creates the screen for adding a new bubble sheet data file to a course.
9500:
9501: =item scantron_upload_scantron_data_save() :
9502:
9503: Adds a provided bubble information data file to the course if user
9504: has the correct privileges to do so.
9505:
9506: =item valid_file() :
9507:
9508: Validates that the requested bubble data file exists in the course.
9509:
9510: =item scantron_download_scantron_data() :
9511:
9512: Shows a list of the three internal files (original, corrected,
9513: skipped) for a specific bubble sheet data file that exists in the
9514: course.
9515:
9516: =item scantron_validate_ID() :
9517:
9518: Validates all scanlines in the selected file to not have any
1.556 weissno 9519: invalid or underspecified student/employee IDs
1.531 jms 9520:
1.582 raeburn 9521: =item navmap_errormsg() :
9522:
9523: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
9524: Should be called whenever the request to instantiate a navmap object fails.
