Nonsense Word Fluency (NWF)


Nonsense Word Fluency (NWF)

• Big Idea:

• Benchmark Goal:

• Assessment Times:

- Alphabetic Principle

- 25 End of K

- 50 End of First

- Kindergarten: Winter, Spring

- First grade: Fall, Winter, Spring


Nonsense Word Fluency

• What Big Idea?

Alphabetic Principle


Materials

Palm PilotPencil-Paper

• Scoring booklet

• Student booklet

• Clipboard

• Stopwatch

• Pen or pencil

• Palm Pilot

• Student booklet


What is the Alphabetic Principle?

• Part 1:

- Alphabetic Understanding: Letters represent sounds in words

am vp s


Alphabetic Principle

• Alphabetic Principle Part 2:

– Phonological Recoding (blending): Letter sounds can be blended together and knowledge of letter-sound associations can be used to read/decode words.

am p


Why Alphabetic Principle?

• Letter-sound knowledge is prerequisite to word identification.

• A primary difference between good and poor readers is the ability to use letter-sound correspondences to decode words.

• Letter-sound knowledge can be taught.

• Teaching the alphabetic principle leads to gains in reading acquisition/achievement.


When Should the Alphabetic Principle be Taught?

• Preschool -- familiarity with alphabet

• Kindergarten -- letter sound correspondences (says common sound associated with individual letters); beginning to blend sounds; recognizes some words by sight.

• First grade -- letter-sound correspondences, decodes nonsense words fluently, reads grade level material accurately.


DIBELS® Nonsense Word Fluency(NWF)

Examiner shows page of nonsense words to student. Student reads the words.

Score:

Number of correct letter sounds student reads in 1 minute

Number of words correctly recoded


Directions for Administration

1. Place the scoring booklet on the clipboard and position so that the student cannot see what you record.

2. Place the page of practice words - “sim” “lut” (student materials) in front of the student.

3. Say these specific directions to the student:


Directions for Administration

Look at this word (point to the first word on the practice page). It’s a make-believe word. Watch me read the word: /s/ /i/ /m/ “sim” (point to each letter then run your finger fast beneath the whole word). I can say the sounds of the letters, /s/ /i/ /m/ (point to each letter), or I can read the whole word “sim” (run your finger fast beneath the whole word).

Your turn to read a make-believe word. Read this word the best you can (point to the word “lut”). Make sure you say any sounds you know.


6. Follow along on the test booklet and underline each letter sound the student says correctly, either in isolation or in the context of the nonsense word. Put a slash (/) over each letter sound read incorrectly.

Directions


7. At the end of 1 minute place a bracket (]) after the last letter sound, say “Stop” and stop your stopwatch.

8. Add the number of correct letter sounds. Record the total number correct on the bottom of the scoring page.

9. Add the number of words correctly recoded and record it at the bottom of the scoring page.

Directions

Note: For progress monitoring, these directions can be shortened by beginning with Number 4 when the student clearly understands the directions and procedure.


Pronunciation Guide

• All NWF nonsense words are phonetically regular V-C and C-V-C words.

– “x” and “q” are not used.

– “h,” “w,” “y,” and “r” are used only in the initial position.

– “c” and “g” are used only in the final position.

– Vowel sounds are short:

• a - “cat”

• e - “bed”

• i - “pig”

• o - “dog”

• u - “cup”


Timing Rule for NWF:Continuous for 1 Minute

• Start the stopwatch after you say, “Begin.”

• At the end of 1 minute place a bracket (]) after the last letter sound, say “Stop” and stop your stopwatch.

Note: If the student is in the middle of a response at the end of 1 minute, you may allow the student to finish the response but only score the sounds said up to end of 1 minute.


Discontinue Rule: First 5 Words

• If the student does not get any sounds correct in the first 5 words, discontinue the task and record a score of zero (0).


Wait Rule for NWF: 3 Seconds

• Maximum time per letter sound is 3 seconds.

• If the student does not say the next letter sound/word within 3 seconds score the letter sound/word incorrect. Tell the student the correct sound/word, and, if necessary, point to the next letter/word and say, “What sound/ word?”


3-Second Rule: Sound-by-Sound

• If the student is saying individual letter sounds and hesitates for 3 seconds on a letter sound, score the letter sound incorrect.

• Say the correct letter sound, and, if necessary, point to the next letter and say “What sound?”

Note: If in doubt about what to prompt, prompt the sound.


Prompting Rule

• If the student says the letter name rather than the letter sound, say, “Remember to tell me the letter sound, not the name.”

• This prompt may be provided once.


Directions for Scoring

1. Underline each letter sound the student says correctly, either in isolation or in the context of the nonsense word.

2. Put a slash (/) over each letter sound read incorrectly.

3. Do not mark any letter sounds omitted, added, or repeated.


Scoring Examples:Underline Correct Letter Sounds

Correct Sounds in Isolation

• Underline the individual letters for each letter sound said correctly in isolation.

Scoring Examples:Underline Correct Letter Sounds

Correct Sounds in Words

• Use a single underline under multiple letters for correct letter sounds blended together. Give credit for each letter-sound correspondence said correctly.

Scoring Examples:Slash Incorrect Letter Sounds

Partially Correct Words

• If a word is partially correct, underline the corresponding letters for letter sounds said correctly.

• Put a slash ( / ) over the letter if the corresponding letter sound is incorrect.

Scoring Examples

Repeated Sounds

• Letter sounds said more than once while sounding out the word are given credit only once.

Note: The student’s final response is scored. If the student sounds out correctly /d/ /o/ /s/ but recodes as “dot,” the student would receive a score or 2 (for the first and middle sounds).


Scoring Examples: Leave Blank

Insertions

• Insertions are not scored as incorrect.

Note

Self Correct

• If a student makes an error and corrects him/herself within 3 seconds, write “SC” above the letter sound or word and count it as correct.

Skips Row

• If a student skips an entire row, draw a line through the row and do not count the row in scoring.


Note

Sound Order – Sound by Sound

• Letter sounds said correctly in isolation but out of order are scored as correct if the student points correctly to the letter(s). (Credit is given for knowledge of individual letter sound correspondences).

NWF Review

• How do I mark letter sounds that are read correctly?

Underline each letter sound read correctly, in isolation or blended or in the context of the whole word.

• How do I mark letter sounds that are read incorrectly?

Slash letter sounds read incorrectly.

• What do I do if the student hesitates for 3 seconds when reading sound-by-sound?

Say the sound, slash the letter, and, if necessary, point to the next letter and ask, “What sound?”

• What do I do if the student hesitates for 3 seconds when reading word-by-word?

Say the word, slash the word and, if necessary, point to the next word and ask, “What word?”

• What do I do if the student reads sounds out of order when reading sound-by-sound?

If the student points correctly to the sounds, score as correct.

• What do I do if the student reads sounds out of order when reading word-by-word?

Score as incorrect.


NWF Summary

Start timer after you say “Begin.”

Correct

(underline letter(s) or word)

Incorrect

(slash letter)

Incorrect

(leave blank)

• Says correct sound for letter

Self-correct: Write “SC” above letter(s)/word and score as correct.

Skips row: Draw a line through the entire row and do not count.
