5801: =head1 Bubble sheet grading routines
5802:
5803: For this documentation:
5804:
5805: 'scanline' refers to the full line of characters
5806: from the file that we are parsing that represents one entire sheet
5807:
5808: 'bubble line' refers to the data
5809: representing the line of bubbles that are on the physical bubblesheet
5810:
5811:
5812: The overall process is that a scanned in bubblesheet data is uploaded
5813: into a course. When a user wants to grade, they select a
5814: sequence/folder of resources, a file of bubblesheet info, and pick
5815: one of the predefined configurations for what each scanline looks
5816: like.
5817:
5818: Next each scanline is checked for any errors of either 'missing
5819: bubbles' (it's an error because it may have been mis-scanned
5820: because too light bubbling), 'double bubble' (each bubble line should
5821: have no more than one letter picked), invalid or duplicated CODE,
5822: invalid student/employee ID
5823:
5824: If the CODE option is used that determines the randomization of the
5825: homework problems, either way the student/employee ID is looked up into a
5826: username:domain.
5827:
5828: During the validation phase the instructor can choose to skip scanlines.

11198: Apache::grades
11199:
11200: =head1 SYNOPSIS
11201:
11202: Handles the viewing of grades.
11203:
11204: This is part of the LearningOnline Network with CAPA project
11205: described at http://www.lon-capa.org.
11206:
11207: =head1 OVERVIEW
11208:
11209: Do an ssi with retries:
11210: While I'd love to factor out this with the vesrion in lonprintout,
11211: 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
11212: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11213:
11214: At least the logic that drives this has been pulled out into loncommon.
11215:
11216:
11217:
11218: ssi_with_retries - Does the server side include of a resource.
11219: if the ssi call returns an error we'll retry it up to
11220: the number of times requested by the caller.
11221: If we still have a problem, no text is appended to the
11222: output and we set some global variables.
11223: to indicate to the caller an SSI error occurred.
11224: All of this is supposed to deal with the issues described
11225: in LON-CAPA BZ 5631 see:
11226: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11227: by informing the user that this happened.
11228:
11229: Parameters:
11230: resource - The resource to include. This is passed directly, without
11231: interpretation to lonnet::ssi.
11232: form - The form hash parameters that guide the interpretation of the resource
11233:
11234: retries - Number of retries allowed before giving up completely.
11235: Returns:
11236: On success, returns the rendered resource identified by the resource parameter.
11237: Side Effects:
11238: The following global variables can be set:
11239: ssi_error - If an unrecoverable error occurred this becomes true.
11240: It is up to the caller to initialize this to false
11241: if desired.
11242: ssi_error_resource - If an unrecoverable error occurred, this is the value
11243: of the resource that could not be rendered by the ssi
11244: call.
11245: ssi_error_message - The error string fetched from the ssi response
11246: in the event of an error.

11263: $r - Apache request object
11264: $i - number of the current scanline
11265: $scan_record - hash ref as returned from &scantron_parse_scanline()
11266: $scan_config - hash ref as returned from &Apache::lonnet::get_scantron_config()

11268: $error - error condition, valid values are
11269: 'incorrectCODE', 'duplicateCODE',
11270: 'doublebubble', 'missingbubble',
11271: 'duplicateID', 'incorrectID'
11272: $arg - extra information needed
11273: For errors:
11274: - duplicateID - paper number that this studentID was seen before on
11275: - duplicateCODE - array ref of the paper numbers this CODE was
11276: seen on before
11277: - incorrectCODE - current incorrect CODE
11278: - doublebubble - array ref of the bubble lines that have double
11279: bubble errors
11280: - missingbubble - array ref of the bubble lines that have missing
11281: bubble errors
11282:
11283: $randomorder - True if exam folder has randomorder set
11284: $randompick - True if exam folder has randompick set
11285: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
11286: for current line to question number used for same question
11287: in "Master Seqence" (as seen by Course Coordinator).
11288: $startline - Reference to hash where key is question number (0 is first)
11289: and value is number of first bubble line for current student
11290: or code-based randompick and/or randomorder.

11293: =item scantron_get_maxbubble() :
11294:
11295: Arguments:
11296: $nav_error - Reference to scalar which is a flag to indicate a
11297: failure to retrieve a navmap object.
11298: if $nav_error is set to 1 by scantron_get_maxbubble(), the
11299: calling routine should trap the error condition and display the warning
11300: found in &navmap_errormsg().
11301:
11302: $scantron_config - Reference to bubblesheet format configuration hash.
11303:
11304: Returns the maximum number of bubble lines that are expected to
11305: occur. Does this by walking the selected sequence rendering the
11306: resource and then checking &Apache::lonxml::get_problem_counter()
11307: for what the current value of the problem counter is.
11308:
11309: Caches the results to $env{'form.scantron_maxbubble'},
11310: $env{'form.scantron.bubble_lines.n'},
11311: $env{'form.scantron.first_bubble_line.n'} and
11312: $env{"form.scantron.sub_bubblelines.n"}
11313: which are the total number of bubble lines, the number of bubble
11314: lines for response n and number of the first bubble line for response n,
11315: and a comma separated list of numbers of bubble lines for sub-questions
11316: (for optionresponse, matchresponse, and rankresponse items), for response n.

11319: =item scantron_validate_missingbubbles() :
11320:
11321: Validates all scanlines in the selected file to not have any
11322: answers that don't have bubbles that have not been verified
11323: to be bubble free.
11324:
11325: =item scantron_process_students() :
11326:
11327: Routine that does the actual grading of the bubblesheet information.
11328:
11329: The parsed scanline hash is added to %env
11330:
11331: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
11332: foreach resource , with the form data of
11333:
11334: 'submitted' =>'scantron'
11335: 'grade_target' =>'grade',
11336: 'grade_username'=> username of student
11337: 'grade_domain' => domain of student
11338: 'grade_courseid'=> of course
11339: 'grade_symb' => symb of resource to grade
11340:
11341: This triggers a grading pass. The problem grading code takes care
11342: of converting the bubbled letter information (now in %env) into a
11343: valid submission.
11344:
11345: =item scantron_upload_scantron_data() :
11346:

11350:
11351: Adds a provided bubble information data file to the course if user

11354: =item valid_file() :
11355:
11356: Validates that the requested bubble data file exists in the course.
11357:
11358: =item scantron_download_scantron_data() :
11359:
11360: Shows a list of the three internal files (original, corrected,
11361: skipped) for a specific bubblesheet data file that exists in the
11362: course.
11363:
11364: =item scantron_validate_ID() :
11365:
11366: Validates all scanlines in the selected file to not have any

11369: =item navmap_errormsg() :
11370:
11371: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
11372: Should be called whenever the request to instantiate a navmap object fails.
