5841: =head1 Bubble sheet grading routines
5842:
5843: For this documentation:
5844:
5845: 'scanline' refers to the full line of characters
5846: from the file that we are parsing that represents one entire sheet
5847:
5848: 'bubble line' refers to the data
5849: representing the line of bubbles that are on the physical bubblesheet
5850:
5851:
5852: The overall process is that a scanned in bubblesheet data is uploaded
5853: into a course. When a user wants to grade, they select a
5854: sequence/folder of resources, a file of bubblesheet info, and pick
5855: one of the predefined configurations for what each scanline looks
5856: like.
5857:
5858: Next each scanline is checked for any errors of either 'missing
5859: bubbles' (it's an error because it may have been mis-scanned
5860: because too light bubbling), 'double bubble' (each bubble line should
5861: have no more than one letter picked), invalid or duplicated CODE,
5862: invalid student/employee ID
5863:
5864: If the CODE option is used that determines the randomization of the
5865: homework problems, either way the student/employee ID is looked up into a
5866: username:domain.
5867:
5868: During the validation phase the instructor can choose to skip scanlines.
5869:
5870: After the validation phase, there are now 3 bubblesheet files
5871:
5872: scantron_original_filename (unmodified original file)
5873: scantron_corrected_filename (file where the corrected information has replaced the original information)
5874: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5875:
5876: Also there is a separate hash nohist_scantrondata that contains extra
5877: correction information that isn't representable in the bubblesheet
5878: file (see &scantron_getfile() for more information)
5879:
5880: After all scanlines are either valid, marked as valid or skipped, then
5881: foreach line foreach problem in the picked sequence, an ssi request is
5882: made that simulates a user submitting their selected letter(s) against
5883: the homework problem.

11296: =head1 NAME
11297:
11298: Apache::grades
11299:
11300: =head1 SYNOPSIS
11301:
11302: Handles the viewing of grades.
11303:
11304: This is part of the LearningOnline Network with CAPA project
11305: described at http://www.lon-capa.org.
11306:
11307: =head1 OVERVIEW
11308:
11309: Do an ssi with retries:
11310: While I'd love to factor out this with the vesrion in lonprintout,
11311: 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
11312: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11313:
11314: At least the logic that drives this has been pulled out into loncommon.
11315:
11316:
11317:
11318: ssi_with_retries - Does the server side include of a resource.
11319: if the ssi call returns an error we'll retry it up to
11320: the number of times requested by the caller.
11321: If we still have a problem, no text is appended to the
11322: output and we set some global variables.
11323: to indicate to the caller an SSI error occurred.
11324: All of this is supposed to deal with the issues described
11325: in LON-CAPA BZ 5631 see:
11326: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11327: by informing the user that this happened.
11328:
11329: Parameters:
11330: resource - The resource to include. This is passed directly, without
11331: interpretation to lonnet::ssi.
11332: form - The form hash parameters that guide the interpretation of the resource
11333:
11334: retries - Number of retries allowed before giving up completely.
11335: Returns:
11336: On success, returns the rendered resource identified by the resource parameter.
11337: Side Effects:
11338: The following global variables can be set:
11339: ssi_error - If an unrecoverable error occurred this becomes true.
11340: It is up to the caller to initialize this to false
11341: if desired.
11342: ssi_error_resource - If an unrecoverable error occurred, this is the value
11343: of the resource that could not be rendered by the ssi
11344: call.
11345: ssi_error_message - The error string fetched from the ssi response
11346: in the event of an error.

11356:
11357: =item scantron_get_correction() :
11358:
11359: Builds the interface screen to interact with the operator to fix a
11360: specific error condition in a specific scanline
11361:
11362: Arguments:
11363: $r - Apache request object
11364: $i - number of the current scanline
11365: $scan_record - hash ref as returned from &scantron_parse_scanline()
11366: $scan_config - hash ref as returned from &Apache::lonnet::get_scantron_config()
11367: $line - full contents of the current scanline
11368: $error - error condition, valid values are
11369: 'incorrectCODE', 'duplicateCODE',
11370: 'doublebubble', 'missingbubble',
11371: 'duplicateID', 'incorrectID'
11372: $arg - extra information needed
11373: For errors:
11374: - duplicateID - paper number that this studentID was seen before on
11375: - duplicateCODE - array ref of the paper numbers this CODE was
11376: seen on before
11377: - incorrectCODE - current incorrect CODE
11378: - doublebubble - array ref of the bubble lines that have double
11379: bubble errors
11380: - missingbubble - array ref of the bubble lines that have missing
11381: bubble errors
11382:
11383: $randomorder - True if exam folder (or a sub-folder) has randomorder set
11384: $randompick - True if exam folder (or a sub-folder) has randompick set
11385: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
11386: for current line to question number used for same question
11387: in "Master Seqence" (as seen by Course Coordinator).
11388: $startline - Reference to hash where key is question number (0 is first)
11389: and value is number of first bubble line for current student
11390: or code-based randompick and/or randomorder.
11391:
11392:
11393: =item scantron_get_maxbubble() :
11394:
11395: Arguments:
11396: $nav_error - Reference to scalar which is a flag to indicate a
11397: failure to retrieve a navmap object.
11398: if $nav_error is set to 1 by scantron_get_maxbubble(), the
11399: calling routine should trap the error condition and display the warning
11400: found in &navmap_errormsg().
11401:
11402: $scantron_config - Reference to bubblesheet format configuration hash.
11403:
11404: Returns the maximum number of bubble lines that are expected to
11405: occur. Does this by walking the selected sequence rendering the
11406: resource and then checking &Apache::lonxml::get_problem_counter()
11407: for what the current value of the problem counter is.
11408:
11409: Caches the results to $env{'form.scantron_maxbubble'},
11410: $env{'form.scantron.bubble_lines.n'},
11411: $env{'form.scantron.first_bubble_line.n'} and
11412: $env{"form.scantron.sub_bubblelines.n"}
11413: which are the total number of bubble lines, the number of bubble
11414: lines for response n and number of the first bubble line for response n,
11415: and a comma separated list of numbers of bubble lines for sub-questions
11416: (for optionresponse, matchresponse, and rankresponse items), for response n.
11417:
11418:
11419: =item scantron_validate_missingbubbles() :
11420:
11421: Validates all scanlines in the selected file to not have any
11422: answers that don't have bubbles that have not been verified
11423: to be bubble free.
11424:
11425: =item scantron_process_students() :
11426:
11427: Routine that does the actual grading of the bubblesheet information.
11428:
11429: The parsed scanline hash is added to %env
11430:
11431: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
11432: foreach resource , with the form data of
11433:
11434: 'submitted' =>'scantron'
11435: 'grade_target' =>'grade',
11436: 'grade_username'=> username of student
11437: 'grade_domain' => domain of student
11438: 'grade_courseid'=> of course
11439: 'grade_symb' => symb of resource to grade
11440:
11441: This triggers a grading pass. The problem grading code takes care
11442: of converting the bubbled letter information (now in %env) into a
11443: valid submission.
11444:
11445: =item scantron_upload_scantron_data() :

11464: =item scantron_validate_ID() :
11465:
11466: Validates all scanlines in the selected file to not have any
11467: invalid or underspecified student/employee IDs
