4638: =head1 Bubble sheet grading routines
4639:
1.424 albertel 4640: For this documentation:
4641:
4642: 'scanline' refers to the full line of characters
4643: from the file that we are parsing that represents one entire sheet
4644:
4645: 'bubble line' refers to the data
4646: representing the line of bubbles that are on the physical bubble sheet
4647:
4648:
4649: The overall process is that a scanned in bubble sheet data is uploaded
4650: into a course. When a user wants to grade, they select a
4651: sequence/folder of resources, a file of bubble sheet info, and pick
4652: one of the predefined configurations for what each scanline looks
4653: like.
4654:
4655: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4656: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4657: because too light bubbling), 'double bubble' (each bubble line should
4658: have no more that one letter picked), invalid or duplicated CODE,
4659: invalid student ID
4660:
4661: If the CODE option is used that determines the randomization of the
4662: homework problems, either way the student ID is looked up into a
4663: username:domain.
4664:
4665: During the validation phase the instructor can choose to skip scanlines.
4666:
1.435 foxr 4667: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4668:
4669: scantron_original_filename (unmodified original file)
4670: scantron_corrected_filename (file where the corrected information has replaced the original information)
4671: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4672:
4673: Also there is a separate hash nohist_scantrondata that contains extra
4674: correction information that isn't representable in the bubble sheet
4675: file (see &scantron_getfile() for more information)
4676:
4677: After all scanlines are either valid, marked as valid or skipped, then
4678: foreach line foreach problem in the picked sequence, an ssi request is
4679: made that simulates a user submitting their selected letter(s) against
4680: the homework problem.

8941: =head1 NAME
8942:
8943: Apache::grades
8944:
8945: =head1 SYNOPSIS
8946:
8947: Handles the viewing of grades.
8948:
8949: This is part of the LearningOnline Network with CAPA project
8950: described at http://www.lon-capa.org.
8951:
8952: =head1 OVERVIEW
8953:
8954: Do an ssi with retries:
8955: While I'd love to factor out this with the vesrion in lonprintout,
8956: 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
8957: I'm not quite ready to invent (e.g. an ssi_with_retry object).
8958:
8959: At least the logic that drives this has been pulled out into loncommon.
8960:
8961:
8962:
8963: ssi_with_retries - Does the server side include of a resource.
8964: if the ssi call returns an error we'll retry it up to
8965: the number of times requested by the caller.
8966: If we still have a proble, no text is appended to the
8967: output and we set some global variables.
8968: to indicate to the caller an SSI error occurred.
8969: All of this is supposed to deal with the issues described
8970: in LonCAPA BZ 5631 see:
8971: http://bugs.lon-capa.org/show_bug.cgi?id=5631
8972: by informing the user that this happened.
8973:
8974: Parameters:
8975: resource - The resource to include. This is passed directly, without
8976: interpretation to lonnet::ssi.
8977: form - The form hash parameters that guide the interpretation of the resource
8978:
8979: retries - Number of retries allowed before giving up completely.
8980: Returns:
8981: On success, returns the rendered resource identified by the resource parameter.
8982: Side Effects:
8983: The following global variables can be set:
8984: ssi_error - If an unrecoverable error occurred this becomes true.
8985: It is up to the caller to initialize this to false
8986: if desired.
8987: ssi_error_resource - If an unrecoverable error occurred, this is the value
8988: of the resource that could not be rendered by the ssi
8989: call.
8990: ssi_error_message - The error string fetched from the ssi response
8991: in the event of an error.

9001:
9002: =item scantron_get_correction() :
9003:
9004: Builds the interface screen to interact with the operator to fix a
9005: specific error condition in a specific scanline
9006:
9007: Arguments:
9008: $r - Apache request object
9009: $i - number of the current scanline
9010: $scan_record - hash ref as returned from &scantron_parse_scanline()
9011: $scan_config - hash ref as returned from &get_scantron_config()
9012: $line - full contents of the current scanline
9013: $error - error condition, valid values are
9014: 'incorrectCODE', 'duplicateCODE',
9015: 'doublebubble', 'missingbubble',
9016: 'duplicateID', 'incorrectID'
9017: $arg - extra information needed
9018: For errors:
9019: - duplicateID - paper number that this studentID was seen before on
9020: - duplicateCODE - array ref of the paper numbers this CODE was
9021: seen on before
9022: - incorrectCODE - current incorrect CODE
9023: - doublebubble - array ref of the bubble lines that have double
9024: bubble errors
9025: - missingbubble - array ref of the bubble lines that have missing
9026: bubble errors
9027:
9028: =item scantron_get_maxbubble() :
9029:
9030: Returns the maximum number of bubble lines that are expected to
9031: occur. Does this by walking the selected sequence rendering the
9032: resource and then checking &Apache::lonxml::get_problem_counter()
9033: for what the current value of the problem counter is.
9034:
9035: Caches the results to $env{'form.scantron_maxbubble'},
9036: $env{'form.scantron.bubble_lines.n'},
9037: $env{'form.scantron.first_bubble_line.n'} and
9038: $env{"form.scantron.sub_bubblelines.n"}
9039: which are the total number of bubble, lines, the number of bubble
9040: lines for response n and number of the first bubble line for response n,
9041: and a comma separated list of numbers of bubble lines for sub-questions
9042: (for optionresponse, matchresponse, and rankresponse items), for response n.
9043:
9044:
9045: =item scantron_validate_missingbubbles() :
9046:
9047: Validates all scanlines in the selected file to not have any
9048: answers that don't have bubbles that have not been verified
9049: to be bubble free.
9050:
9051: =item scantron_process_students() :
9052:
9053: Routine that does the actual grading of the bubble sheet information.
9054:
9055: The parsed scanline hash is added to %env
9056:
9057: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9058: foreach resource , with the form data of
9059:
9060: 'submitted' =>'scantron'
9061: 'grade_target' =>'grade',
9062: 'grade_username'=> username of student
9063: 'grade_domain' => domain of student
9064: 'grade_courseid'=> of course
9065: 'grade_symb' => symb of resource to grade
9066:
9067: This triggers a grading pass. The problem grading code takes care
9068: of converting the bubbled letter information (now in %env) into a
9069: valid submission.
9070:
9071: =item scantron_upload_scantron_data() :
9072:
9073: Creates the screen for adding a new bubble sheet data file to a course.
9074:
9075: =item scantron_upload_scantron_data_save() :
9076:
9077: Adds a provided bubble information data file to the course if user
9078: has the correct privileges to do so.
9079:
9080: =item valid_file() :
9081:
9082: Validates that the requested bubble data file exists in the course.
9083:
9084: =item scantron_download_scantron_data() :
9085:
9086: Shows a list of the three internal files (original, corrected,
9087: skipped) for a specific bubble sheet data file that exists in the
9088: course.
9089:
9090: =item scantron_validate_ID() :
9091:
9092: Validates all scanlines in the selected file to not have any
9093: invalid or underspecified student IDs
