4637: =head1 Bubble sheet grading routines
4638:
1.424 albertel 4639: For this documentation:
4640:
4641: 'scanline' refers to the full line of characters
4642: from the file that we are parsing that represents one entire sheet
4643:
4644: 'bubble line' refers to the data
4645: representing the line of bubbles that are on the physical bubble sheet
4646:
4647:
4648: The overall process is that a scanned in bubble sheet data is uploaded
4649: into a course. When a user wants to grade, they select a
4650: sequence/folder of resources, a file of bubble sheet info, and pick
4651: one of the predefined configurations for what each scanline looks
4652: like.
4653:
4654: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4655: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4656: because too light bubbling), 'double bubble' (each bubble line should
4657: have no more that one letter picked), invalid or duplicated CODE,
4658: invalid student ID
4659:
4660: If the CODE option is used that determines the randomization of the
4661: homework problems, either way the student ID is looked up into a
4662: username:domain.
4663:
4664: During the validation phase the instructor can choose to skip scanlines.
4665:
1.435 foxr 4666: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4667:
4668: scantron_original_filename (unmodified original file)
4669: scantron_corrected_filename (file where the corrected information has replaced the original information)
4670: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4671:
4672: Also there is a separate hash nohist_scantrondata that contains extra
4673: correction information that isn't representable in the bubble sheet
4674: file (see &scantron_getfile() for more information)
4675:
4676: After all scanlines are either valid, marked as valid or skipped, then
4677: foreach line foreach problem in the picked sequence, an ssi request is
4678: made that simulates a user submitting their selected letter(s) against
4679: the homework problem.

9009: =head1 NAME
9010:
9011: Apache::grades
9012:
9013: =head1 SYNOPSIS
9014:
9015: Handles the viewing of grades.
9016:
9017: This is part of the LearningOnline Network with CAPA project
9018: described at http://www.lon-capa.org.
9019:
9020: =head1 OVERVIEW
9021:
9022: Do an ssi with retries:
9023: While I'd love to factor out this with the vesrion in lonprintout,
9024: 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
9025: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9026:
9027: At least the logic that drives this has been pulled out into loncommon.
9028:
9029:
9030:
9031: ssi_with_retries - Does the server side include of a resource.
9032: if the ssi call returns an error we'll retry it up to
9033: the number of times requested by the caller.
9034: If we still have a proble, no text is appended to the
9035: output and we set some global variables.
9036: to indicate to the caller an SSI error occurred.
9037: All of this is supposed to deal with the issues described
9038: in LonCAPA BZ 5631 see:
9039: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9040: by informing the user that this happened.
9041:
9042: Parameters:
9043: resource - The resource to include. This is passed directly, without
9044: interpretation to lonnet::ssi.
9045: form - The form hash parameters that guide the interpretation of the resource
9046:
9047: retries - Number of retries allowed before giving up completely.
9048: Returns:
9049: On success, returns the rendered resource identified by the resource parameter.
9050: Side Effects:
9051: The following global variables can be set:
9052: ssi_error - If an unrecoverable error occurred this becomes true.
9053: It is up to the caller to initialize this to false
9054: if desired.
9055: ssi_error_resource - If an unrecoverable error occurred, this is the value
9056: of the resource that could not be rendered by the ssi
9057: call.
9058: ssi_error_message - The error string fetched from the ssi response
9059: in the event of an error.

9070: =item scantron_get_correction() :
9071:
9072: Builds the interface screen to interact with the operator to fix a
9073: specific error condition in a specific scanline
9074:
9075: Arguments:
9076: $r - Apache request object
9077: $i - number of the current scanline
9078: $scan_record - hash ref as returned from &scantron_parse_scanline()
9079: $scan_config - hash ref as returned from &get_scantron_config()
9080: $line - full contents of the current scanline
9081: $error - error condition, valid values are
9082: 'incorrectCODE', 'duplicateCODE',
9083: 'doublebubble', 'missingbubble',
9084: 'duplicateID', 'incorrectID'
9085: $arg - extra information needed
9086: For errors:
9087: - duplicateID - paper number that this studentID was seen before on
9088: - duplicateCODE - array ref of the paper numbers this CODE was
9089: seen on before
9090: - incorrectCODE - current incorrect CODE
9091: - doublebubble - array ref of the bubble lines that have double
9092: bubble errors
9093: - missingbubble - array ref of the bubble lines that have missing
9094: bubble errors
9095:
9096: =item scantron_get_maxbubble() :
9097:
9098: Returns the maximum number of bubble lines that are expected to
9099: occur. Does this by walking the selected sequence rendering the
9100: resource and then checking &Apache::lonxml::get_problem_counter()
9101: for what the current value of the problem counter is.
9102:
9103: Caches the results to $env{'form.scantron_maxbubble'},
9104: $env{'form.scantron.bubble_lines.n'},
9105: $env{'form.scantron.first_bubble_line.n'} and
9106: $env{"form.scantron.sub_bubblelines.n"}
9107: which are the total number of bubble, lines, the number of bubble
9108: lines for response n and number of the first bubble line for response n,
9109: and a comma separated list of numbers of bubble lines for sub-questions
9110: (for optionresponse, matchresponse, and rankresponse items), for response n.
9111:
9112:
9113: =item scantron_validate_missingbubbles() :
9114:
9115: Validates all scanlines in the selected file to not have any
9116: answers that don't have bubbles that have not been verified
9117: to be bubble free.
9118:
9119: =item scantron_process_students() :
9120:
9121: Routine that does the actual grading of the bubble sheet information.
9122:
9123: The parsed scanline hash is added to %env
9124:
9125: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9126: foreach resource , with the form data of
9127:
9128: 'submitted' =>'scantron'
9129: 'grade_target' =>'grade',
9130: 'grade_username'=> username of student
9131: 'grade_domain' => domain of student
9132: 'grade_courseid'=> of course
9133: 'grade_symb' => symb of resource to grade
9134:
9135: This triggers a grading pass. The problem grading code takes care
9136: of converting the bubbled letter information (now in %env) into a
9137: valid submission.
9138:
9139: =item scantron_upload_scantron_data() :
9140:
9141: Creates the screen for adding a new bubble sheet data file to a course.
9142:
9143: =item scantron_upload_scantron_data_save() :
9144:
9145: Adds a provided bubble information data file to the course if user
9146: has the correct privileges to do so.
9147:
9148: =item valid_file() :
9149:
9150: Validates that the requested bubble data file exists in the course.
9151:
9152: =item scantron_download_scantron_data() :
9153:
9154: Shows a list of the three internal files (original, corrected,
9155: skipped) for a specific bubble sheet data file that exists in the
9156: course.
9157:
9158: =item scantron_validate_ID() :
9159:
9160: Validates all scanlines in the selected file to not have any
9161: invalid or underspecified student IDs
