5201: =head1 Bubble sheet grading routines
5202:
5203: For this documentation:
5204:
5205: 'scanline' refers to the full line of characters
5206: from the file that we are parsing that represents one entire sheet
5207:
5208: 'bubble line' refers to the data
5209: representing the line of bubbles that are on the physical bubblesheet
5210:
5211:
5212: The overall process is that a scanned in bubblesheet data is uploaded
5213: into a course. When a user wants to grade, they select a
5214: sequence/folder of resources, a file of bubblesheet info, and pick
5215: one of the predefined configurations for what each scanline looks
5216: like.
5217:
5218: Next each scanline is checked for any errors of either 'missing
5219: bubbles' (it's an error because it may have been mis-scanned
5220: because too light bubbling), 'double bubble' (each bubble line should
5221: have no more that one letter picked), invalid or duplicated CODE,
5222: invalid student/employee ID
5223:
5224: If the CODE option is used that determines the randomization of the
5225: homework problems, either way the student/employee ID is looked up into a
5226: username:domain.
5227:
5228: During the validation phase the instructor can choose to skip scanlines.
5229:
5230: After the validation phase, there are now 3 bubblesheet files
5231:
5232: scantron_original_filename (unmodified original file)
5233: scantron_corrected_filename (file where the corrected information has replaced the original information)
5234: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5235:
5236: Also there is a separate hash nohist_scantrondata that contains extra
5237: correction information that isn't representable in the bubblesheet
5238: file (see &scantron_getfile() for more information)
5239:
5240: After all scanlines are either valid, marked as valid or skipped, then
5241: foreach line foreach problem in the picked sequence, an ssi request is
5242: made that simulates a user submitting their selected letter(s) against
5243: the homework problem.

10068: =head1 NAME
10069:
10070: Apache::grades
10071:
10072: =head1 SYNOPSIS
10073:
10074: Handles the viewing of grades.
10075:
10076: This is part of the LearningOnline Network with CAPA project
10077: described at http://www.lon-capa.org.
10078:
10079: =head1 OVERVIEW
10080:
10081: Do an ssi with retries:
10082: While I'd love to factor out this with the vesrion in lonprintout,
10083: 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
10084: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10085:
10086: At least the logic that drives this has been pulled out into loncommon.
10087:
10088:
10089:
10090: ssi_with_retries - Does the server side include of a resource.
10091: if the ssi call returns an error we'll retry it up to
10092: the number of times requested by the caller.
10093: If we still have a proble, no text is appended to the
10094: output and we set some global variables.
10095: to indicate to the caller an SSI error occurred.
10096: All of this is supposed to deal with the issues described
10097: in LonCAPA BZ 5631 see:
10098: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10099: by informing the user that this happened.
10100:
10101: Parameters:
10102: resource - The resource to include. This is passed directly, without
10103: interpretation to lonnet::ssi.
10104: form - The form hash parameters that guide the interpretation of the resource
10105:
10106: retries - Number of retries allowed before giving up completely.
10107: Returns:
10108: On success, returns the rendered resource identified by the resource parameter.
10109: Side Effects:
10110: The following global variables can be set:
10111: ssi_error - If an unrecoverable error occurred this becomes true.
10112: It is up to the caller to initialize this to false
10113: if desired.
10114: ssi_error_resource - If an unrecoverable error occurred, this is the value
10115: of the resource that could not be rendered by the ssi
10116: call.
10117: ssi_error_message - The error string fetched from the ssi response
10118: in the event of an error.

10128:
10129: =item scantron_get_correction() :
10130:
10131: Builds the interface screen to interact with the operator to fix a
10132: specific error condition in a specific scanline
10133:
10134: Arguments:
10135: $r - Apache request object
10136: $i - number of the current scanline
10137: $scan_record - hash ref as returned from &scantron_parse_scanline()
10138: $scan_config - hash ref as returned from &get_scantron_config()
10139: $line - full contents of the current scanline
10140: $error - error condition, valid values are
10141: 'incorrectCODE', 'duplicateCODE',
10142: 'doublebubble', 'missingbubble',
10143: 'duplicateID', 'incorrectID'
10144: $arg - extra information needed
10145: For errors:
10146: - duplicateID - paper number that this studentID was seen before on
10147: - duplicateCODE - array ref of the paper numbers this CODE was
10148: seen on before
10149: - incorrectCODE - current incorrect CODE
10150: - doublebubble - array ref of the bubble lines that have double
10151: bubble errors
10152: - missingbubble - array ref of the bubble lines that have missing
10153: bubble errors
10154:
10155: =item scantron_get_maxbubble() :
10156:
10157: Arguments:
10158: $nav_error - Reference to scalar which is a flag to indicate a
10159: failure to retrieve a navmap object.
10160: if $nav_error is set to 1 by scantron_get_maxbubble(), the
10161: calling routine should trap the error condition and display the warning
10162: found in &navmap_errormsg().
10163:
10164: $scantron_config - Reference to bubblesheet format configuration hash.
10165:
10166: Returns the maximum number of bubble lines that are expected to
10167: occur. Does this by walking the selected sequence rendering the
10168: resource and then checking &Apache::lonxml::get_problem_counter()
10169: for what the current value of the problem counter is.
10170:
10171: Caches the results to $env{'form.scantron_maxbubble'},
10172: $env{'form.scantron.bubble_lines.n'},
10173: $env{'form.scantron.first_bubble_line.n'} and
10174: $env{"form.scantron.sub_bubblelines.n"}
10175: which are the total number of bubble, lines, the number of bubble
10176: lines for response n and number of the first bubble line for response n,
10177: and a comma separated list of numbers of bubble lines for sub-questions
10178: (for optionresponse, matchresponse, and rankresponse items), for response n.
10179:
10180:
10181: =item scantron_validate_missingbubbles() :
10182:
10183: Validates all scanlines in the selected file to not have any
10184: answers that don't have bubbles that have not been verified
10185: to be bubble free.
10186:
10187: =item scantron_process_students() :
10188:
10189: Routine that does the actual grading of the bubblesheet information.
10190:
10191: The parsed scanline hash is added to %env
10192:
10193: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
10194: foreach resource , with the form data of
10195:
10196: 'submitted' =>'scantron'
10197: 'grade_target' =>'grade',
10198: 'grade_username'=> username of student
10199: 'grade_domain' => domain of student
10200: 'grade_courseid'=> of course
10201: 'grade_symb' => symb of resource to grade
10202:
10203: This triggers a grading pass. The problem grading code takes care
10204: of converting the bubbled letter information (now in %env) into a
10205: valid submission.
10206:
10207: =item scantron_upload_scantron_data() :
10208:
10209: Creates the screen for adding a new bubblesheet data file to a course.
10210:
10211: =item scantron_upload_scantron_data_save() :
10212:
10213: Adds a provided bubble information data file to the course if user
10214: has the correct privileges to do so.
10215:
10216: =item valid_file() :
10217:
10218: Validates that the requested bubble data file exists in the course.
10219:
10220: =item scantron_download_scantron_data() :
10221:
10222: Shows a list of the three internal files (original, corrected,
10223: skipped) for a specific bubblesheet data file that exists in the
10224: course.
10225:
10226: =item scantron_validate_ID() :
10227:
10228: Validates all scanlines in the selected file to not have any
10229: invalid or underspecified student/employee IDs
10230:
10231: =item navmap_errormsg() :
10232:
10233: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
10234: Should be called whenever the request to instantiate a navmap object fails.
