5847: =head1 Bubble sheet grading routines
5848:
5849: For this documentation:
5850:
5851: 'scanline' refers to the full line of characters
5852: from the file that we are parsing that represents one entire sheet
5853:
5854: 'bubble line' refers to the data
5855: representing the line of bubbles that are on the physical bubblesheet
5856:
5857:
5858: The overall process is that a scanned in bubblesheet data is uploaded
5859: into a course. When a user wants to grade, they select a
5860: sequence/folder of resources, a file of bubblesheet info, and pick
5861: one of the predefined configurations for what each scanline looks
5862: like.
5863:
5864: Next each scanline is checked for any errors of either 'missing
5865: bubbles' (it's an error because it may have been mis-scanned
5866: because too light bubbling), 'double bubble' (each bubble line should
5867: have no more than one letter picked), invalid or duplicated CODE,
5868: invalid student/employee ID
5869:
5870: If the CODE option is used that determines the randomization of the
5871: homework problems, either way the student/employee ID is looked up into a
5872: username:domain.
5873:
5874: During the validation phase the instructor can choose to skip scanlines.
5875:
5876: After the validation phase, there are now 3 bubblesheet files
5877:
5878: scantron_original_filename (unmodified original file)
5879: scantron_corrected_filename (file where the corrected information has replaced the original information)
5880: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5881:
5882: Also there is a separate hash nohist_scantrondata that contains extra
5883: correction information that isn't representable in the bubblesheet
5884: file (see &scantron_getfile() for more information)
5885:
5886: After all scanlines are either valid, marked as valid or skipped, then
5887: foreach line foreach problem in the picked sequence, an ssi request is
5888: made that simulates a user submitting their selected letter(s) against
5889: the homework problem.

11302: =head1 NAME
11303:
11304: Apache::grades
11305:
11306: =head1 SYNOPSIS
11307:
11308: Handles the viewing of grades.
11309:
11310: This is part of the LearningOnline Network with CAPA project
11311: described at http://www.lon-capa.org.
11312:
11313: =head1 OVERVIEW
11314:
11315: Do an ssi with retries:
11316: While I'd love to factor out this with the vesrion in lonprintout,
11317: 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
11318: I'm not quite ready to invent (e.g. an ssi_with_retry object).
11319:
11320: At least the logic that drives this has been pulled out into loncommon.
11321:
11322:
11323:
11324: ssi_with_retries - Does the server side include of a resource.
11325: if the ssi call returns an error we'll retry it up to
11326: the number of times requested by the caller.
11327: If we still have a problem, no text is appended to the
11328: output and we set some global variables.
11329: to indicate to the caller an SSI error occurred.
11330: All of this is supposed to deal with the issues described
11331: in LON-CAPA BZ 5631 see:
11332: http://bugs.lon-capa.org/show_bug.cgi?id=5631
11333: by informing the user that this happened.
11334:
11335: Parameters:
11336: resource - The resource to include. This is passed directly, without
11337: interpretation to lonnet::ssi.
11338: form - The form hash parameters that guide the interpretation of the resource
11339:
11340: retries - Number of retries allowed before giving up completely.
11341: Returns:
11342: On success, returns the rendered resource identified by the resource parameter.
11343: Side Effects:
11344: The following global variables can be set:
11345: ssi_error - If an unrecoverable error occurred this becomes true.
11346: It is up to the caller to initialize this to false
11347: if desired.
11348: ssi_error_resource - If an unrecoverable error occurred, this is the value
11349: of the resource that could not be rendered by the ssi
11350: call.
11351: ssi_error_message - The error string fetched from the ssi response
11352: in the event of an error.

11362:
11363: =item scantron_get_correction() :
11364:
11365: Builds the interface screen to interact with the operator to fix a
11366: specific error condition in a specific scanline
11367:
11368: Arguments:
11369: $r - Apache request object
11370: $i - number of the current scanline
11371: $scan_record - hash ref as returned from &scantron_parse_scanline()
11372: $scan_config - hash ref as returned from &Apache::lonnet::get_scantron_config()
11373: $line - full contents of the current scanline
11374: $error - error condition, valid values are
11375: 'incorrectCODE', 'duplicateCODE',
11376: 'doublebubble', 'missingbubble',
11377: 'duplicateID', 'incorrectID'
11378: $arg - extra information needed
11379: For errors:
11380: - duplicateID - paper number that this studentID was seen before on
11381: - duplicateCODE - array ref of the paper numbers this CODE was
11382: seen on before
11383: - incorrectCODE - current incorrect CODE
11384: - doublebubble - array ref of the bubble lines that have double
11385: bubble errors
11386: - missingbubble - array ref of the bubble lines that have missing
11387: bubble errors
11388:
11389: $randomorder - True if exam folder (or a sub-folder) has randomorder set
11390: $randompick - True if exam folder (or a sub-folder) has randompick set
11391: $respnumlookup - Reference to HASH mapping question numbers in bubble lines
11392: for current line to question number used for same question
11393: in "Master Seqence" (as seen by Course Coordinator).
11394: $startline - Reference to hash where key is question number (0 is first)
11395: and value is number of first bubble line for current student
11396: or code-based randompick and/or randomorder.
11397:
11398:
11399: =item scantron_get_maxbubble() :
11400:
11401: Arguments:
11402: $nav_error - Reference to scalar which is a flag to indicate a
11403: failure to retrieve a navmap object.
11404: if $nav_error is set to 1 by scantron_get_maxbubble(), the
11405: calling routine should trap the error condition and display the warning
11406: found in &navmap_errormsg().
11407:
11408: $scantron_config - Reference to bubblesheet format configuration hash.
11409:
11410: Returns the maximum number of bubble lines that are expected to
11411: occur. Does this by walking the selected sequence rendering the
11412: resource and then checking &Apache::lonxml::get_problem_counter()
11413: for what the current value of the problem counter is.
11414:
11415: Caches the results to $env{'form.scantron_maxbubble'},
11416: $env{'form.scantron.bubble_lines.n'},
11417: $env{'form.scantron.first_bubble_line.n'} and
11418: $env{"form.scantron.sub_bubblelines.n"}
11419: which are the total number of bubble lines, the number of bubble
11420: lines for response n and number of the first bubble line for response n,
11421: and a comma separated list of numbers of bubble lines for sub-questions
11422: (for optionresponse, matchresponse, and rankresponse items), for response n.
11423:
11424:
11425: =item scantron_validate_missingbubbles() :
11426:
11427: Validates all scanlines in the selected file to not have any
11428: answers that don't have bubbles that have not been verified
11429: to be bubble free.
11430:
11431: =item scantron_process_students() :
11432:
11433: Routine that does the actual grading of the bubblesheet information.
11434:
11435: The parsed scanline hash is added to %env
11436:
11437: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
11438: foreach resource , with the form data of
11439:
11440: 'submitted' =>'scantron'
11441: 'grade_target' =>'grade',
11442: 'grade_username'=> username of student
11443: 'grade_domain' => domain of student
11444: 'grade_courseid'=> of course
11445: 'grade_symb' => symb of resource to grade
11446:
11447: This triggers a grading pass. The problem grading code takes care
11448: of converting the bubbled letter information (now in %env) into a
11449: valid submission.
11450:
11451: =item scantron_upload_scantron_data() :
11452:

11467: skipped) for a specific bubblesheet data file that exists in the
11468: course.
11469:
11470: =item scantron_validate_ID() :
11471:
11472: Validates all scanlines in the selected file to not have any
11473: invalid or underspecified student/employee IDs
11474:
11475: =item navmap_errormsg() :
11476:
11477: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
