4690: =head1 Bubble sheet grading routines
4691:
4692: For this documentation:
4693:
4694: 'scanline' refers to the full line of characters
4695: from the file that we are parsing that represents one entire sheet
4696:
4697: 'bubble line' refers to the data
4698: representing the line of bubbles that are on the physical bubble sheet
4699:
4700:
4701: The overall process is that a scanned in bubble sheet data is uploaded
4702: into a course. When a user wants to grade, they select a
4703: sequence/folder of resources, a file of bubble sheet info, and pick
4704: one of the predefined configurations for what each scanline looks
4705: like.
4706:
4707: Next each scanline is checked for any errors of either 'missing
4708: bubbles' (it's an error because it may have been mis-scanned
4709: because too light bubbling), 'double bubble' (each bubble line should
4710: have no more that one letter picked), invalid or duplicated CODE,
4711: invalid student/employee ID
4712:
4713: If the CODE option is used that determines the randomization of the
4714: homework problems, either way the student/employee ID is looked up into a
4715: username:domain.
4716:
4717: During the validation phase the instructor can choose to skip scanlines.
4718:
4719: After the validation phase, there are now 3 bubble sheet files
4720:
4721: scantron_original_filename (unmodified original file)
4722: scantron_corrected_filename (file where the corrected information has replaced the original information)
4723: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4724:
4725: Also there is a separate hash nohist_scantrondata that contains extra
4726: correction information that isn't representable in the bubble sheet
4727: file (see &scantron_getfile() for more information)
4728:
4729: After all scanlines are either valid, marked as valid or skipped, then
4730: foreach line foreach problem in the picked sequence, an ssi request is
4731: made that simulates a user submitting their selected letter(s) against
4732: the homework problem.

9112: =head1 NAME
9113:
9114: Apache::grades
9115:
9116: =head1 SYNOPSIS
9117:
9118: Handles the viewing of grades.
9119:
9120: This is part of the LearningOnline Network with CAPA project
9121: described at http://www.lon-capa.org.
9122:
9123: =head1 OVERVIEW
9124:
9125: Do an ssi with retries:
9126: While I'd love to factor out this with the vesrion in lonprintout,
9127: 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
9128: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9129:
9130: At least the logic that drives this has been pulled out into loncommon.
9131:
9132:
9133:
9134: ssi_with_retries - Does the server side include of a resource.
9135: if the ssi call returns an error we'll retry it up to
9136: the number of times requested by the caller.
9137: If we still have a proble, no text is appended to the
9138: output and we set some global variables.
9139: to indicate to the caller an SSI error occurred.
9140: All of this is supposed to deal with the issues described
9141: in LonCAPA BZ 5631 see:
9142: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9143: by informing the user that this happened.
9144:
9145: Parameters:
9146: resource - The resource to include. This is passed directly, without
9147: interpretation to lonnet::ssi.
9148: form - The form hash parameters that guide the interpretation of the resource
9149:
9150: retries - Number of retries allowed before giving up completely.
9151: Returns:
9152: On success, returns the rendered resource identified by the resource parameter.
9153: Side Effects:
9154: The following global variables can be set:
9155: ssi_error - If an unrecoverable error occurred this becomes true.
9156: It is up to the caller to initialize this to false
9157: if desired.
9158: ssi_error_resource - If an unrecoverable error occurred, this is the value
9159: of the resource that could not be rendered by the ssi
9160: call.
9161: ssi_error_message - The error string fetched from the ssi response
9162: in the event of an error.

9173: =item scantron_get_correction() :
9174:
9175: Builds the interface screen to interact with the operator to fix a
9176: specific error condition in a specific scanline
9177:
9178: Arguments:
9179: $r - Apache request object
9180: $i - number of the current scanline
9181: $scan_record - hash ref as returned from &scantron_parse_scanline()
9182: $scan_config - hash ref as returned from &get_scantron_config()
9183: $line - full contents of the current scanline
9184: $error - error condition, valid values are
9185: 'incorrectCODE', 'duplicateCODE',
9186: 'doublebubble', 'missingbubble',
9187: 'duplicateID', 'incorrectID'
9188: $arg - extra information needed
9189: For errors:
9190: - duplicateID - paper number that this studentID was seen before on
9191: - duplicateCODE - array ref of the paper numbers this CODE was
9192: seen on before
9193: - incorrectCODE - current incorrect CODE
9194: - doublebubble - array ref of the bubble lines that have double
9195: bubble errors
9196: - missingbubble - array ref of the bubble lines that have missing
9197: bubble errors
9198:
9199: =item scantron_get_maxbubble() :
9200:
9201: Returns the maximum number of bubble lines that are expected to
9202: occur. Does this by walking the selected sequence rendering the
9203: resource and then checking &Apache::lonxml::get_problem_counter()
9204: for what the current value of the problem counter is.
9205:
9206: Caches the results to $env{'form.scantron_maxbubble'},
9207: $env{'form.scantron.bubble_lines.n'},
9208: $env{'form.scantron.first_bubble_line.n'} and
9209: $env{"form.scantron.sub_bubblelines.n"}
9210: which are the total number of bubble, lines, the number of bubble
9211: lines for response n and number of the first bubble line for response n,
9212: and a comma separated list of numbers of bubble lines for sub-questions
9213: (for optionresponse, matchresponse, and rankresponse items), for response n.
9214:
9215:
9216: =item scantron_validate_missingbubbles() :
9217:
9218: Validates all scanlines in the selected file to not have any
9219: answers that don't have bubbles that have not been verified
9220: to be bubble free.
9221:
9222: =item scantron_process_students() :
9223:
9224: Routine that does the actual grading of the bubble sheet information.
9225:
9226: The parsed scanline hash is added to %env
9227:
9228: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9229: foreach resource , with the form data of
9230:
9231: 'submitted' =>'scantron'
9232: 'grade_target' =>'grade',
9233: 'grade_username'=> username of student
9234: 'grade_domain' => domain of student
9235: 'grade_courseid'=> of course
9236: 'grade_symb' => symb of resource to grade
9237:
9238: This triggers a grading pass. The problem grading code takes care
9239: of converting the bubbled letter information (now in %env) into a
9240: valid submission.
9241:
9242: =item scantron_upload_scantron_data() :
9243:
9244: Creates the screen for adding a new bubble sheet data file to a course.
9245:
9246: =item scantron_upload_scantron_data_save() :
9247:
9248: Adds a provided bubble information data file to the course if user
9249: has the correct privileges to do so.
9250:
9251: =item valid_file() :
9252:
9253: Validates that the requested bubble data file exists in the course.
9254:
9255: =item scantron_download_scantron_data() :
9256:
9257: Shows a list of the three internal files (original, corrected,
9258: skipped) for a specific bubble sheet data file that exists in the
9259: course.
9260:
9261: =item scantron_validate_ID() :
9262:
9263: Validates all scanlines in the selected file to not have any
9264: invalid or underspecified student/employee IDs
