Phoneme Segmentation Fluency (PSF)

• Big Idea:

• Benchmark Goal:

• Assessment Times:

- Phonemic Awareness

- 35 end of K– 18 at middle of K

- Kindergarten:Winter, spring

- First Grade:Fall, winter, spring

Note: PSF may also be used with older students who may not have the skill.

Phoneme Segmentation Fluency

• What Big Idea?

Phonemic Awareness

Materials

Palm PilotPencil-Paper

• Scoring booklet

• Clipboard

• Stopwatch

• Pen or pencil

• Palm Pilot

5

What is Phonemic Awareness?

• The awareness and understanding of the sound structure of our language

• Understanding that spoken words are made up of sequences of individual speech sounds:

– “cat” is composed of the sounds /k/ /a/ /t/

6

Phonemic Awareness

• What is a phoneme?

– Smallest unit of speech that makes a difference to the meaning of a word

• How many phonemes are in the word…

bat?

boat?

both?

cloth?

clothes?

3 /b/ /a/ /t/

3 /b/ /oa/ /t/

3 /b/ /oa/ /th/

4 /k/ /l/ /o/ /th/

5 /k/ /l/ /oa/ /TH/ /z/

7

Phonemic Awareness Tasks

• Phoneme isolation: Tell me the first sound in boy. (/b/)

• Phoneme identity: Tell me the sound that is the same in bike, boy, and bell. (/b/)

• Phoneme categorization: Which word does not belong? Bus, bun, rug (rug)

• Phoneme blending: What word is /t/ /ea/ /ch/? (teach)

• Phoneme segmentation: What are the sounds in ship? (/sh/ /i/ /p/)

• Phoneme deletion: What is smile without the s? (mile)

Is Phonemic Awareness the same as Phonological Awareness?

Phonological awareness is the “umbrella.”

If you can do it with your eyes closed, it is phonemic awareness!

Is Phonemic Awareness the Same as Phonics?

10

Why Phonemic Awareness?

• Phonemic Awareness is essential to learning to read in an alphabetic writing system. – Letters represent sounds/phonemes

– Phonemic awareness is fundamental to mapping speech sounds to print.

– Without phonemic awareness, phonics makes little sense.

• Phonemic Awareness is a strong predictor of children’s reading acquisition and achievement.

• Phonemic Awareness can be taught; reading outcomes are improved when children are taught phonemic awareness.

11

When Should Phonemic Awareness be Taught?

• Preschool -- Listening to sounds, alliteration, rhyming.

• Kindergarten-- Isolating first sound in 1-syllable words; Blending 3-4 phonemes into one word; Segmenting individual sounds in words.

• First Grade -- Segmenting and manipulating individual sounds in words.

12

Phoneme Segmentation Fluency (PSF)

Examiner says a word. Student says the sounds in the word.

Score: Number of correct sound segments student says in 1 minute.

13

Directions for Administration

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

Say these specific directions to the student:

I am going to say a word. After I say it, you tell me all the sounds in the word. So, if I say, “Sam,” you would say /s/ /a/ /m/. Let’s try one. (one second pause) Tell me the sounds in “mop.”

14

3. Say the first word and start your stopwatch.

4. As the student says the sounds, mark the student response in the scoring column.

• Underline each different, correct part of the word that the student says.

• Put a slash ( / ) through incorrect sounds.

• Leave omitted sounds blank.

• Circle repeated words.

Directions

15

5. As soon as the student is finished saying the sounds, present the next word promptly and clearly.

6. At the end of 1 minute, place a bracket (]) after the last sound segment, stop presenting words and scoring further responses.

7. Add the number of correct sound segments. Record the total number of correct sound segments on the bottom of the scoring page.

Directions

16

Timing Rule for PSF: Continuous for 1 Minute

• Start the stopwatch after you say the first word.

• At the end of 1 minute place a bracket (]) after the last sound segment, say “Stop” and stop your stopwatch. Do not present more words. Do not score further responses.

17

Wait Rule for PSF: 3 Seconds

• Maximum time for each sound segment is 3 seconds.

• If the student does not say the next sound segment within 3 seconds, say the next word.

18

Discontinue Rule: First 5 Words

• If a student has not said any sound segments correctly in the first 5 words, discontinue the task and record a score of zero (0).

19

Prompting Rule

• If a student has done the examples correctly and does not respond correctly to the words, say, “Remember to tell me the sounds in the word.”

• This prompt may be given once.

20

Directions for Scoring

• Underline the correct sound segments the student says.

• Students receive 1 point for each different, correct, part of the word.

• Put a slash ( / ) through segments pronounced incorrectly.

• Leave segments that are omitted blank.

• Circle entire words.

21

Scoring Examples: Underline Correct Sound Segments

STUDENT SCORING CORRECTWORD: SAYS: PROCEDURE: SEGMENTS:

trick /t/…/r/…/i/…/k/ /t/ /r/ /i/ /k/ 4 /4cat /k/…/a/…/t/ /k/ /a/ /t/ 3 /3

Correct Phoneme Segmentation Examiner says “trick,” student says “/t/ /r/ /i/ /k/”.

Examiner says “cat,” student says “/k/ /a/ /t/”.

Note: Sounds pronounced with a schwa (/u/) are judged to be correct (e.g., tu…ru…i…ku; ku…a…tu).

22

Incomplete Segmentation

Examiner says “trick,” student says “/tr/ /ik/”. Examiner says “cat,” student says “/k/ /at/”.


trick /tr/ /ik/ /t/ /r/ /i/ /k/ 2 /4cat /k/ /at/ /k/ /a/ /t/ 2 /3


23

Overlapping Segmentation

Examiner says “trick,” student says “/tri/ /ik/.”Examiner says “cat,” student says “/ka/ /a/ /at/.”


trick “/tri/ /ik/” /t/ /r/ /i/ /k/ 2 /4cat “/ka/ /a/ /t/” /k/ /a/ /t/ 3 /3


24

Sound Elongation (Continuous blending)

Examiner says “rest,” student says “rrrrreeeesssttt.”


rest “rrrreeeessssttt” /r/ /e/ /s/ /t/ 4 /4

Scoring Examples:Underline Correct Sound Segments

25

Incorrect Sound

Examiner says “trick,” student says “t...r...i...p.”Examiner says “cat,” student says “b...a...t.”


trick “t...r...i...p” /t/ /r/ /i/ /k/ 3 /4cat “b…a...t” /k/ /a/ /t/ 2 /3trick “t…r…uk” /t/ /r/ /i/ /k/ 2 /4cat “k…ut” /k/ /a/ /t/ 1 /3

Scoring Examples: Slash (/) Incorrect Sound Segments

Note: The sound segment as a whole is judged to be correct or incorrect.

26

Additions

Examiner says “trick,” student says “t...r...i...ck...s.”Examiner says “cat,” student says “s...c...a...t.”


trick “t...r...i...k…s” /t/ /r/ /i/ /k/ 4 /4cat “s…c...a...t” /k/ /a/ /t/ 3 /3

Scoring Examples: Leave Blank

27

Omissions

Examiner says “trick,” student says “t...ick.”Examiner says “cat,” student says /k/...(3 seconds).

STUDENT SCORING CORRECTWORD: SAYS: PROCEDURE: SEGMENTS

trick “t...ik” /t/ /r/ /i/ /k/ 2 /4cat “c” (3 seconds) /k/ /a/ /t/ 1 /3

Scoring Examples: Leave Blank

28

No Segmentation Examiner says “trick,” student says “trick.” Examiner says “cat,” student says “cat.”

Note: If a student segments a part of the word and then repeats the word, underline the sound and then circle the word.


trick “trick” /t/ /r/ /i/ /k/ 0 /4cat “cat” /k/ /a/ /t/ 0 /3

cat /k/ /kat/ /k/ /a/ /t/ 1 /3

Scoring Examples: Circle

29

Scoring Examples: No Score

“I don’t know” Examiner says “trick,” student says “I don’t know” or “I don’t know that one.”

Do not underline; wait 3 seconds and say the next word.


trick “I don’t know.” /t/ /r/ /i/ /k/ 0 /4cat “I don’t know.” /k/ /a/ /t/ 0 /3

30


rest “r…e…th…t” /r/ /e/ /s/ /t/ 4 /4

Note

Articulation and Dialect

• The student is not penalized for imperfect pronunciation due to dialect, articulation, or different first language.

• Example: Examiner says “rest,” the student who consistently says /th/ for /s/ says “r…e…th…t.”

31

Final Score: Scoring Page

• Add number of correct sound segments for each line (up to bracket). Record total for each line in space provided in right hand column of scoring page.

• Add number of correct sound segments from each line. Record total number of correct sound segments in space provided in lower right hand corner of scoring

page.
