The Mnemonic Value of Orthography for Vocabulary Learning

 Collaborator: Julie Rosenthal

Mnemonic value – improving memory

Orthography – spellings of words

Two Ways to read words

Ways to Read Words

UNFAMILIAR WORDS

 By Decoding:

– Graphemes -> Phonemes

– Larger units: spelling patterns for syllables or morphemes

FAMILIAR WORDS

 By Memory or Sight

– Note: All words when practiced become read from memory

Reading Words from Memory

 Process of forming connections

Spelling glue

Pronunciation

Meaning

Knowledge of the grapheme-phoneme system provides the glue connecting spellings to pronunciations in memory

Examples of connections for regularly spelled words

Knowledge needed to form connections

 Phoneme segmentation

– To analyze pronunciations into phonemes

 Grapheme-phoneme correspondences

– To access constituents of the writing system ( the glue )

 Grapho-phonemic matching

– To connect graphemes to phonemes within specific words

10

Connections for Specific Words are

Learned Quickly

 Reitsma (1983)

- Taught 1 st graders to read words

- Minimum of 4 practice trials to read words from memory

Share (2004) – self teaching mechanism

- 1 exposure to words in text for 3 rd graders

- Memory for letters persisted one month

Application to Vocabulary Learning

11

Examined connection forming process as it contributes to vocabulary learning

Explicit Word Learning Task:

– Students rehearsed pronunciations and meanings of new words over several trials

Procedure:

– Initial study trial: words and meanings were introduced

 Pictures and defining sentences

– Several test trials with feedback followed

Experimental Manipulation

Treatment condition : spellings of words were shown during study and feedback periods but NOT when recall of words was tested

Control condition : same except spellings of words were not shown

Hypothesis and Explanation

12

 Hypothesis : Students will learn the pronunciations and meanings of words more readily when they are exposed to spellings of the words during study periods than when they are not exposed to spellings.

 Explanation : Grapheme-phoneme connections are activated by spellings and will better secure the words in memory.

First Experiment

 N = 20 2 nd graders, Mean age = 7yrs. 7 months

Pretests

 Woodcock word identification: M = 2.2 grade-equivalent

 CVC nonword reading (M=55%) and spelling (M=53%)

Word Learning Conditions

 They were taught two sets of 6 concrete nouns and their meanings

One set: spellings of words accompanied learning

The other set: spellings did not accompany learning

Counterbalancing

Examples:

Gam – family of whales

Cur – a homeless dog

Sod – wet, grassy ground

Fet – big, fun party

Nib – tip of a pen

Yag – fake jewelry

Spelling Seen Condition :

Initial study trial : Student hears each word and a defining sentence, sees picture and written word, repeats word and sentence

(picture) gam

(picture) yag

(picture) sod

(picture) fet

(picture) nib

(picture) yag

An example:

Nib

Spelling Seen Condition :

Word Recall Test Trial : Student sees each picture and recalls word. Then word is seen, pronounced, and heard in a sentence. Students repeats the word and its sentence.

sod

Spelling Seen Condition :

Definition Recall Test Trial : Student hears and sees each word and recalls its meaning. Then meaning is given, and student repeats the word and its meaning.

18

No-Spelling Condition:

 Procedures are the same as in the Spelling

Condition

– Except:

 Spellings of words are never shown

 Students pronounce the words extra times

Summary of word learning events

Each child learns one set of vocabulary words with spellings and another set without spellings

One initial study trial to introduce words

Followed by trials to test recall of words and definitions

Word recall trials are interleaved with definition recall trials

Maximum of 9 trials are provided to learn words and meanings

Note: Spellings of words are not shown when words are tested, so recall depends upon having the spellings of words in memory .

Conclusion and explanation

 Conclusion : 2 nd graders learned vocabulary words and their meanings better when they were exposed to spellings of the words than when they only practiced speaking the words

 Explanation:

– Pronunciations were unfamiliar.

Grapho-phonemic connections better secured their representations in memory

Stronger base for attaching meanings

Second Experiment

 N = 32 5th graders , Mean age = 10 yrs. 11 months

Pretests

Reading words and nonwords; spelling words; vocabulary test;

Reader Ability Groups (word reading task)

Higher Readers (7.3 GE) vs. Lower Readers (4.6 GE)

Word Learning Conditions

They were taught two sets of 10 concrete nouns and their meanings

One set: spellings accompanied word learning

One set: spellings did not accompany word learning

Maximum of 8 trials to achieve 3 perfect successive trials

Examples:

– Barrow: a small hill

Tandem: a horse-drawn carriage

Fribble: a foolish shallow person

Tamarack: a big tree found all over America

Proboscis: a really big nose

Hypotheses

 Spellings will help 5 th graders learn the pronunciations and meanings of new vocabulary words

 Students with stronger orthographic knowledge (hi readers) will benefit more from spellings than students with weaker orthographic knowledge (lo readers)

Conclusions

31

 Seeing spellings helped 5 th graders learn the pronunciations and meanings of new vocabulary words more than not seeing spellings.

 Students with strong orthographic knowledge benefited more from seeing spellings than students with weak orthographic knowledge

 Matthew Effect: rich getting richer over time

Explanation: grapho-phonemic connections better secured pronunciations of words in memory; better specified pronunciations provided a stronger base for learning meanings.

 Effect incidental: no attention directed at spellings; no instruction to decode words; automatic activation of mapping relations

32

Implications for Vocabulary Instruction and Learning

 Grapho-phonemic instruction :

- It is important for students to acquire strong orthographic knowledge as they learn to read

 Strategy instruction :

– When students encounter new vocabulary words, they should be taught to examine the spellings of the words as they pronounce them aloud or as they listen to someone else pronounce them
