4690:
1.424 albertel 4691: For this documentation:
4692:
4693: 'scanline' refers to the full line of characters
4694: from the file that we are parsing that represents one entire sheet
4695:
4696: 'bubble line' refers to the data
4697: representing the line of bubbles that are on the physical bubble sheet
4698:
4699:
4700: The overall process is that a scanned in bubble sheet data is uploaded
4701: into a course. When a user wants to grade, they select a
4702: sequence/folder of resources, a file of bubble sheet info, and pick
4703: one of the predefined configurations for what each scanline looks
4704: like.
4705:
4706: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4707: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4708: because too light bubbling), 'double bubble' (each bubble line should
4709: have no more that one letter picked), invalid or duplicated CODE,
1.556 weissno 4710: invalid student/employee ID
1.424 albertel 4711:
4712: If the CODE option is used that determines the randomization of the
1.556 weissno 4713: homework problems, either way the student/employee ID is looked up into a
1.424 albertel 4714: username:domain.
4715:
4716: During the validation phase the instructor can choose to skip scanlines.
4717:
1.435 foxr 4718: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4719:
4720: scantron_original_filename (unmodified original file)
4721: scantron_corrected_filename (file where the corrected information has replaced the original information)
4722: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4723:
4724: Also there is a separate hash nohist_scantrondata that contains extra
4725: correction information that isn't representable in the bubble sheet
4726: file (see &scantron_getfile() for more information)
4727:
4728: After all scanlines are either valid, marked as valid or skipped, then
4729: foreach line foreach problem in the picked sequence, an ssi request is
4730: made that simulates a user submitting their selected letter(s) against
4731: the homework problem.

9111: =head1 NAME
9112:
9113: Apache::grades
9114:
9115: =head1 SYNOPSIS
9116:
9117: Handles the viewing of grades.
9118:
9119: This is part of the LearningOnline Network with CAPA project
9120: described at http://www.lon-capa.org.
9121:
9122: =head1 OVERVIEW
9123:
9124: Do an ssi with retries:
9125: While I'd love to factor out this with the vesrion in lonprintout,
9126: 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
9127: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9128:
9129: At least the logic that drives this has been pulled out into loncommon.
9130:
9131:
9132:
9133: ssi_with_retries - Does the server side include of a resource.
9134: if the ssi call returns an error we'll retry it up to
9135: the number of times requested by the caller.
9136: If we still have a proble, no text is appended to the
9137: output and we set some global variables.
9138: to indicate to the caller an SSI error occurred.
9139: All of this is supposed to deal with the issues described
9140: in LonCAPA BZ 5631 see:
9141: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9142: by informing the user that this happened.
9143:
9144: Parameters:
9145: resource - The resource to include. This is passed directly, without
9146: interpretation to lonnet::ssi.
9147: form - The form hash parameters that guide the interpretation of the resource
9148:
9149: retries - Number of retries allowed before giving up completely.
9150: Returns:
9151: On success, returns the rendered resource identified by the resource parameter.
9152: Side Effects:
9153: The following global variables can be set:
9154: ssi_error - If an unrecoverable error occurred this becomes true.
9155: It is up to the caller to initialize this to false
9156: if desired.
9157: ssi_error_resource - If an unrecoverable error occurred, this is the value
9158: of the resource that could not be rendered by the ssi
9159: call.
9160: ssi_error_message - The error string fetched from the ssi response
9161: in the event of an error.

9174: Builds the interface screen to interact with the operator to fix a
9175: specific error condition in a specific scanline
9176:
9177: Arguments:
9178: $r - Apache request object
9179: $i - number of the current scanline
9180: $scan_record - hash ref as returned from &scantron_parse_scanline()
9181: $scan_config - hash ref as returned from &get_scantron_config()
9182: $line - full contents of the current scanline
9183: $error - error condition, valid values are
9184: 'incorrectCODE', 'duplicateCODE',
9185: 'doublebubble', 'missingbubble',
9186: 'duplicateID', 'incorrectID'
9187: $arg - extra information needed
9188: For errors:
9189: - duplicateID - paper number that this studentID was seen before on
9190: - duplicateCODE - array ref of the paper numbers this CODE was
9191: seen on before
9192: - incorrectCODE - current incorrect CODE
9193: - doublebubble - array ref of the bubble lines that have double
9194: bubble errors
9195: - missingbubble - array ref of the bubble lines that have missing
9196: bubble errors
9197:
9198: =item scantron_get_maxbubble() :
9199:
9200: Returns the maximum number of bubble lines that are expected to
9201: occur. Does this by walking the selected sequence rendering the
9202: resource and then checking &Apache::lonxml::get_problem_counter()
9203: for what the current value of the problem counter is.
9204:
9205: Caches the results to $env{'form.scantron_maxbubble'},
9206: $env{'form.scantron.bubble_lines.n'},
9207: $env{'form.scantron.first_bubble_line.n'} and
9208: $env{"form.scantron.sub_bubblelines.n"}
9209: which are the total number of bubble, lines, the number of bubble
9210: lines for response n and number of the first bubble line for response n,
9211: and a comma separated list of numbers of bubble lines for sub-questions
9212: (for optionresponse, matchresponse, and rankresponse items), for response n.
9213:
9214:
9215: =item scantron_validate_missingbubbles() :
9216:
9217: Validates all scanlines in the selected file to not have any
9218: answers that don't have bubbles that have not been verified
9219: to be bubble free.
9220:
9221: =item scantron_process_students() :
9222:
9223: Routine that does the actual grading of the bubble sheet information.
9224:
9225: The parsed scanline hash is added to %env
9226:
9227: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9228: foreach resource , with the form data of
9229:
9230: 'submitted' =>'scantron'
9231: 'grade_target' =>'grade',
9232: 'grade_username'=> username of student
9233: 'grade_domain' => domain of student
9234: 'grade_courseid'=> of course
9235: 'grade_symb' => symb of resource to grade
9236:
9237: This triggers a grading pass. The problem grading code takes care
9238: of converting the bubbled letter information (now in %env) into a
9239: valid submission.
9240:
9241: =item scantron_upload_scantron_data() :
9242:
9243: Creates the screen for adding a new bubble sheet data file to a course.

9246:

9258: course.
9259:
