4635: =head1 Bubble sheet grading routines
4636:
1.424 albertel 4637: For this documentation:
4638:
4639: 'scanline' refers to the full line of characters
4640: from the file that we are parsing that represents one entire sheet
4641:
4642: 'bubble line' refers to the data
4643: representing the line of bubbles that are on the physical bubble sheet
4644:
4645:
4646: The overall process is that a scanned in bubble sheet data is uploaded
4647: into a course. When a user wants to grade, they select a
4648: sequence/folder of resources, a file of bubble sheet info, and pick
4649: one of the predefined configurations for what each scanline looks
4650: like.
4651:
4652: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4653: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4654: because too light bubbling), 'double bubble' (each bubble line should
4655: have no more that one letter picked), invalid or duplicated CODE,
4656: invalid student ID
4657:
4658: If the CODE option is used that determines the randomization of the
4659: homework problems, either way the student ID is looked up into a
4660: username:domain.
4661:
4662: During the validation phase the instructor can choose to skip scanlines.
4663:
1.435 foxr 4664: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4665:
4666: scantron_original_filename (unmodified original file)
4667: scantron_corrected_filename (file where the corrected information has replaced the original information)
4668: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4669:
4670: Also there is a separate hash nohist_scantrondata that contains extra
4671: correction information that isn't representable in the bubble sheet
4672: file (see &scantron_getfile() for more information)
4673:
4674: After all scanlines are either valid, marked as valid or skipped, then
4675: foreach line foreach problem in the picked sequence, an ssi request is
4676: made that simulates a user submitting their selected letter(s) against
4677: the homework problem.

8939: =head1 NAME
8940:
8941: Apache::grades
8942:
8943: =head1 SYNOPSIS
8944:
8945: Handles the viewing of grades.
8946:
8947: This is part of the LearningOnline Network with CAPA project
8948: described at http://www.lon-capa.org.
8949:
8950: =head1 OVERVIEW
8951:
8952: Do an ssi with retries:
8953: While I'd love to factor out this with the vesrion in lonprintout,
8954: 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
8955: I'm not quite ready to invent (e.g. an ssi_with_retry object).
8956:
8957: At least the logic that drives this has been pulled out into loncommon.
8958:
8959:
8960:
8961: ssi_with_retries - Does the server side include of a resource.
8962: if the ssi call returns an error we'll retry it up to
8963: the number of times requested by the caller.
8964: If we still have a proble, no text is appended to the
8965: output and we set some global variables.
8966: to indicate to the caller an SSI error occurred.
8967: All of this is supposed to deal with the issues described
8968: in LonCAPA BZ 5631 see:
8969: http://bugs.lon-capa.org/show_bug.cgi?id=5631
8970: by informing the user that this happened.
8971:
8972: Parameters:
8973: resource - The resource to include. This is passed directly, without
8974: interpretation to lonnet::ssi.
8975: form - The form hash parameters that guide the interpretation of the resource
8976:
8977: retries - Number of retries allowed before giving up completely.
8978: Returns:
8979: On success, returns the rendered resource identified by the resource parameter.
8980: Side Effects:
8981: The following global variables can be set:
8982: ssi_error - If an unrecoverable error occurred this becomes true.
8983: It is up to the caller to initialize this to false
8984: if desired.
8985: ssi_error_resource - If an unrecoverable error occurred, this is the value
8986: of the resource that could not be rendered by the ssi
8987: call.
8988: ssi_error_message - The error string fetched from the ssi response
8989: in the event of an error.

9000: =item scantron_get_correction() :
9001:
9002: Builds the interface screen to interact with the operator to fix a
9003: specific error condition in a specific scanline
9004:
9005: Arguments:
9006: $r - Apache request object
9007: $i - number of the current scanline
9008: $scan_record - hash ref as returned from &scantron_parse_scanline()
9009: $scan_config - hash ref as returned from &get_scantron_config()
9010: $line - full contents of the current scanline
9011: $error - error condition, valid values are
9012: 'incorrectCODE', 'duplicateCODE',
9013: 'doublebubble', 'missingbubble',
9014: 'duplicateID', 'incorrectID'
9015: $arg - extra information needed
9016: For errors:
9017: - duplicateID - paper number that this studentID was seen before on
9018: - duplicateCODE - array ref of the paper numbers this CODE was
9019: seen on before
9020: - incorrectCODE - current incorrect CODE
9021: - doublebubble - array ref of the bubble lines that have double
9022: bubble errors
9023: - missingbubble - array ref of the bubble lines that have missing
9024: bubble errors
9025:
9026: =item scantron_get_maxbubble() :
9027:
9028: Returns the maximum number of bubble lines that are expected to
9029: occur. Does this by walking the selected sequence rendering the
9030: resource and then checking &Apache::lonxml::get_problem_counter()
9031: for what the current value of the problem counter is.
9032:
9033: Caches the results to $env{'form.scantron_maxbubble'},
9034: $env{'form.scantron.bubble_lines.n'},
9035: $env{'form.scantron.first_bubble_line.n'} and
9036: $env{"form.scantron.sub_bubblelines.n"}
9037: which are the total number of bubble, lines, the number of bubble
9038: lines for response n and number of the first bubble line for response n,
9039: and a comma separated list of numbers of bubble lines for sub-questions
9040: (for optionresponse, matchresponse, and rankresponse items), for response n.
9041:
9042:
9043: =item scantron_validate_missingbubbles() :
9044:
9045: Validates all scanlines in the selected file to not have any
9046: answers that don't have bubbles that have not been verified
9047: to be bubble free.
9048:
9049: =item scantron_process_students() :
9050:
9051: Routine that does the actual grading of the bubble sheet information.
9052:
9053: The parsed scanline hash is added to %env
9054:
9055: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9056: foreach resource , with the form data of
9057:
9058: 'submitted' =>'scantron'
9059: 'grade_target' =>'grade',
9060: 'grade_username'=> username of student
9061: 'grade_domain' => domain of student
9062: 'grade_courseid'=> of course
9063: 'grade_symb' => symb of resource to grade
9064:
9065: This triggers a grading pass. The problem grading code takes care
9066: of converting the bubbled letter information (now in %env) into a
9067: valid submission.
9068:
9069: =item scantron_upload_scantron_data() :
9070:
9071: Creates the screen for adding a new bubble sheet data file to a course.
9072:
9073: =item scantron_upload_scantron_data_save() :
9074:
9075: Adds a provided bubble information data file to the course if user
9076: has the correct privileges to do so.
9077:
9078: =item valid_file() :
9079:
9080: Validates that the requested bubble data file exists in the course.
9081:
9082: =item scantron_download_scantron_data() :
9083:
9084: Shows a list of the three internal files (original, corrected,
9085: skipped) for a specific bubble sheet data file that exists in the
9086: course.
9087:
9088: =item scantron_validate_ID() :
9089:
9090: Validates all scanlines in the selected file to not have any
9091: invalid or underspecified student IDs
