PHONOLOGICAL AWARENFSS - Deaf-Ed-Parent-Infant
VOLUME 1 47. No. 3, 2002 PHONOLOGICAL AWARENFSS: ONE KEY To THE READIVG PROFICIENCY OF DEAF CHILDREN case is made for the importance of children's development of phonological awareness-whether they are hearing or deaf-if they are to reach their potential as readers. Relevant terms are defined (i.e., phonologicalawareness, phonological processes, and phonics) to assist the reader with the research review, which covers (a) the typical stages irk the acquisition of phonological awareness and (b) phonological awareness and deafness. Suggestions for phonological awareness assessment are offered, along with the recommendation that the use of recently developed formal and informal measures of phonological awareness might facilitate the setting of goals and objectives when deaf educators or speechlanguage pathologists are evaluating the skills of deaf students and planning instruction for these students. Such tools yield information about skills that have been shown to correlate with literacy attainment and that are not commonly addressed by deaf educators or speech-language pathologists serving deaf students. Finally, research concerning thLe facilitation of phonological awareness and its application is explained. DIANE CO1RC ORAN NIELSEN ANI) BAIBARA LUETKE-STAHLMAN Nielsen is an associate professor in the Department of Teaching and Leadership, University of Kansas, Lawrence. Luetke-Stahiman is a national consultant in deaf education and reading education based in Elm City, NC. VOLUME 147, No. 3, 2002 If they are to participate in contemporary society, it is critical that childrcn become proficient readers, whether they are deaf or hearing, monolingual or bilingual, developing normally or experiencing cognitive or learning disabilities. Currently. most deaf students are educated in public schools (Moores, 1999) and are expected to comprehend and be critical readers of a variety of text types (textbooks, materiAi from the Internet, resource books, newsrriagazines, etc.) and to demonstrate the same proficiency on achievement tests shown by their hearing classmates. Such reading experiences prepare deaf students :o pursue higher education and a multittude of careers, just as is true of their heating peers. tJnfortunately, most deaf students historically plateau at the third- or fourth-grade level in reading and writing achievement (see reviews by Moores, 1996; Paul, 1998). Concern about the reading achievement of students in the United States and the need for all children to get off to a good start as readers is on the national educational agenda, and rightly so. The National Assessment of Educational Progress (NAEP), commonly known as the `nation's report card," evaluates the reading ability of thousands of 4th-, 8th-, and 12th-grade students every few years, and sets high standards for reading performance. The present time is widely understood as an era in which the ability to read and comprehend information is critical in all walks of life, so it is particularly disconcerting that a report of the 1998 NAEP findings indicated that only 31% of 4th graders, 33% of 8th graders, and 400%6 of 12th graders were reading at the proficient level or higher. Proficient perfonnance is defined as "solid academic performance for each grade assessed. Students AMERICAN ANNAtS OFTHE DEAF PHONOLOGICAL AWARENESS reaching this level have demonstrated competency over challenging subject matter, including subject-matter knowledge, application of such knowledge to real-world situations, and analytical skills appropriate to the subject matter" (:NAEP, 2001). Similar NAEP findings in the past decade lecd to the commission of national studies related to reading. In 1990 Marilyn Adams, hirecd to investigate 'what we know about basis processes and instructional priorities in words and letter identification and early reading" (Adams, 1990, p. vi), concluded that the acqtuisition of phonological awareness and English-language proficiency is essential if children are to be able to efficiently decipher words and to understand text withlout continual assistance. Two additional national stuclies were coumissioned, one focusing on preventing reacling difficulties (Snow, 13urns, & Griffin, 1998) and the oduer on researchbased reading instruction (National Reading Panel, 2000). A key finding of all three of these extensive national studies is that phonological awareness, particularly phonemic or sound-level awareness, plays an important role in later reading achievement. It is possible that the lack of phonological awareness is a contributing factor to the reported low levels of reading achievement of many deaf children. Some teachers may reject this possibility, having had cleaf children in their classes who appeared to readl as capably as their hearing peers in the early primary grades because they could recognize written words as wiholes or hecause they used rudimentary phonological skills. However, after completing a longitudinal study of first graclers, Perfetti, Beck, Bell, and H-Iughes (1987) concluded that although children can rely on their visual memory of letters to `read" worcls initially, continuedl progress requires the development of phonological awareness. So while the ultimate goal of reading is comprehension, readers must first "unlock" (or read) the words on the printed page and then develop a VOI-UME 147, No. 3, 2002 bank of words that they recognize quickly and efficiently (Ehri, 1995). Since English is an alphabetic language, readers must be able to map sounds to the letters and the letter sequences they represent. As the empirical evidence provided in the present article indicates, although deaf stuclents may not hear sounds at all or may not hear them clearly, they still can and mutst develop phlonological awareness if they are to reacd the soundbased printecl words an(l phrases of English. tlnlocking a word allows a child to identify or read it. According to Peter V. Paul (1998), a researchier ancl educator wiho is deaf himself, word identification, in wlhich a reader gradually becomes awxare of' the concept, pronunciation, cue, or sign for an unknown worcl, "is the foundation of the literacy process" (p. 34). There is a wealth of research with hearing children on the phonological awareness/ word recognition connection (see reviews by Adams, 1990; National Reading Panel, 2000; Snow et al., 1998: Vellutino & Scanlon, 1987). Researchers lhave foLund that students w ho have acquirecl phonological awareness (i.e., sensitivity to sound patterns of the language), be they hearing or deaf, have an advantage in being ahle to identify unknown words. When the subskills ot' phonological awareness are taught, the reading achievement of childlren improves (see reviews by Adams, 1990; Bryen & Gerber, 1987; National Reading Panel, 2000; Snow et al., 1998). Many parents, teachers, and researchers involved in deaf education may be skeptical that deaf children can acquire phonological awareness. We reviewed the literature to see if a causal relationship between phoniological awareness and reading achievement in deaf reaclers was evidenced. We were guicded in this task by the work of Keith Stanovich (1986), a respected reading researcher, whio suggested that several types of eviclence must be obtained in order to docuLment a causal relationship between either a particular skill and reading achievement, or between training in a particular skill and reading achievement. Such evidence includes longitudinal data demonstrating the predlictive validity of the hypothesized skill; data from contrasts of readers of different skills and ages, matched for reading achievement; and data from studies demonstrating that training in critical skills improves reading performance. While the results of such research with deaf students, particularly data training and longitudinal data, are not as amply available, we believe there is sufficient evidence to warrant attention to phonological awareness instruction for deaf children. Therefore, our purpose in the present article is to review the literature on the relationship between phonological awareness and reading proficiency, and to make suggestions for assessing and facilitating this proficiency. We focus on children with hearing loss, acknowledging that additional research would benefit the parents and professionals who seek ways to help deaf students become proficient readers. Clearly supported by the research, our position is that phonological awareness is necessary, but not sufficient, for the development of reading proficiency. Phonological Awareness Snow et al. (1998) defined phonological awareness as "sensitivity to the patterns of spoken language that recur and can be manipulated without respect to the meaning [that word parts or words] ordinarily convey" (p. 319). The phonological aspects of language as they relate empirically to independent word recognition also involve the awareness of sound(s) at the syllable, onset-rime, and phoneme levels (Goswami, 2000). Phonological awareness obviously is related to the phonology of English and training in speech articulation, as studied by teachers of the Deaf. The realization that such skills can be developed in deaf children AMERICAN ANNALS OF THE DEAF 's40 is more likely when Hanson's definition of phonological units (1989) is considered. She defines them as ;meaningless primitives that are not actually sounds, but are related to movements articulated by the vocal tract of the speaker" (p. 73). When phonological awareness skills are discussed at the "sound" level, they are referred to as phonemic awareness abilities. Phonemes are "smaller-thansyllable" speech sounds that roughly correspond to individual letters (Adams, 1990, p. 65). For example, the word cat is made up of three phonemes or sounds, as is the word cake. Adams added that it is neither the ability to hear the cdifference between phonemes nor the ability to clistinctly articulate them that is significant. Instead, what is important is the awareness that phonemes exist as components, or "the building blocks of a language," that can be manipulatecl and, when combined, form morphemies, the smallest meaningful units of language. (For example, the word cat is made up of one morpheme ancl the word cats of two.) Adams further reported that "developmentally, this awareness seems to depend upon the child's inclination or encouragement to lend conscious attention to the sounds as distinct from the meaning of words" (p. 65). Phonemic awareness is a type of metalinguistic awareness that involves understanding that words are composed of individual, distinct sounds that can be manipulated. Skills at this level that relate to reading achievement include matching words with the same initial sound, and isolating, segmenting, blending, deleting, and substituting phonemes (jorm & Share, 1983; Share, Jorm, MacLean, & Matthews, 1984). For example, given the word ball, students would be asked to say only the first sound (/b/) [souncl isolation], or to say all the sounds in the word (/b/ .../a/ .../1/) [sound segmentation]. Alternately, students might be given the separate souncls of a word (/b/ /a/ /1/) and asked to blend them into the word (bal/). More challenging phonemic ma- VOLUME147, VOLUME 147, No. 3, 2002 nipulations include saying a word such as ballwithout the initial sound [letion] or substituting the /t/ sound for the /b/ sound to create a new word, tall [substitution] (Yopp, 1988). Phonological Processes Three primary phonological processes that relate to reading are phonics, phonological recoding, and rhyming (see review by LaSasso & Metzger, 1998). Each involves phonological representations that collectively have been termed "inner speech" (Paul &Jackson, 1993) or "inner code" (Kleiman, 1975). Kleiman wrote that inner code is "a transformation of printed words into any type of speech-basecl code, whether it be articulatory, acoustic, auditory imagery, or a more abstract code" (p. 323). Vygotsky (1934/1987) cescribed inner cocle as "thought connected with words" (p. 249), a concept othe-s have labeled "phonological recoding" (Jorm & Share, 1983), "phonemic recoding" (Raynor & I'ollatsek, 1989), "speech recoding" (Kleiman, 1975), "silent speech" (Edfeldt, 1960), "subvocal speech' (Locke, 1970), an(l "implicit speech" (Lepley, 1952). Besner (1987) also described internal phonological representa-ions, avoiding the assumption that one has to hear and speak to possess them. B3addeley (1979) wrote that an internal code is essential in dlecoding printed words and recording them in memory, and in processing surface grammar to derive deep structure. Likewise, Paul (1998) noted that the use of a phonological code in short-term memory is most efficient for sentence comprehension because of the development of rapid, automo tic, and fluent word-identification skills. The ability to quickly identify words allows readers to comprehend more text and to focus more energy on the comprehension task. Results of a study by Conrad (1979) indicated that use of an internal code by (leaf students correlated with hearing level, intelligence, and reading achievement. o. 3, 2002 Phonics Phonics is the understanding of how sounds are mappe(l onto letters. While decoding is "obviously a difficult task for students with hearing loss" (Paul, 1998, p. 201), Leybaert (1993) found that deaf students raised orally, as well as those who signed, could acquire knowledge of sound-to-grapheme relationships or phonics. Neither sign nor fingerspelling were shown to interfere with the development of phonological awareness (Bebko, 1998; Harris & Beech, 1998; Lichtenstein, 1998; P. Miller, 1997). It is thus evident that signing and nonsigning deaf students use phonic knowledge both to distinguish possible letter combinations from implausible ones and to recognize words. Investigations by researchers such as Conracl (1979); Hanson, Liberman, and Shankweiler (1984); and Quenin (1982) gave support to this finding, which was later confirmed by Gibbs (1989), Hanson (1989), Hanson and Fowler (1987), Lichtenstein (1985), Marschark (1993), and Tzeng (1993). Recent studies involving deaf children have demonstrated that students exposed to Cued Speech have phonic abilities that more closely resemble those of hearing peers than those of deaf peers who are from noncueing backgrounds or who are in situations in which cueing is used only at school (e.g., Leybaert & Charlier, 1996). Phonological Recoding Phonologicalrecoding is the translation of letters and letter patterns as they are produced in the mouth, palate, and nasal area into sounds or kinesthetic feelings (Tunmer, 1990). Lillo-Martin, Hanson, and Smith (1992) found that "working memory is more efficient for reading when the processing involves phonological recoding" (p. 147). Phonological recoding also is referred to as phonological assembly and "depends on the ability to make letter-tosound or spelling-to-articulation transformations" (Marschark, 1993, p. 209). Marschark suggestecl that readers wlho A ERICAN ANNAL OF THE DEA AMERICAN ANNALS OF1 HE IIOEAF PHONOLOGICAL A WARENESS are young or who are performing at below-average levels may need to store phonological representations, such as strings of letters or syllables, in working memory temporarily while phonologically assembling or sounding out a worcl. That is, phonological abilities enhance the working memory capacity of deaf sttidents (see review by LaSasso & Metzger, 1998). Other researchers in deaf ecducation (e.g., Conrad, 1970), 1973; Hanson, 1986; Hanson et al., 1984; J. L.ocke & V. Locke, 1971) have fotund that working rmemory capacity is a strong predictor of reading achievement for deaf readers, even stronger than degree of hearing loss. Paul and Jackson (1993) reviewedi the research on phonological recodinig and deafness and found that there is increasing evidence that speechi recoding is important for reading coIIIprehension to access the meaning of words (p. 137). They referred to phonological recoding variously as sutbvocalization" and 'the movements of muscle and other bodly parts in the vocal tract" (p. 137), and distinguislhecd the process from those of phonological coding, mental representations, and auditory imaging of speech. Based on a continual review of the literacy and deafness research (e.g., Paul & Quigley, 1994), Paul (1998) suggested that instruction and practice should be provicded to children who can hear some speech sounds, and should inclucle the cliscrimination and identification of sounds in relation to print. The use of a speech-based code, unlike the use of a sign code, is related to reading achievement in most stuclies examining phonological recoding abilities (e.g., Conrad, 1979; Hanson et al., 1984; Lichtenstein, 1998; Wandel, 1989). Kelly (1995) found that deaf sttu- dents benefit from instruction by general and special education teachers, as well as by speech-language pathologists who emphasize speechreading and expressive speech practices as means of improving these students' access to and use of speech-recoding processing. Rhyming The ability to rhyme is also a wordlevel phonological awareness skill, and many researchers have found the ability to rhlytne to be a predictor of reading achievement. Accordcing to Goswarmi and Bryant, as reported by Copeland. Winsor, ancl Osborn (1994), children who are more sensitive to rhyme or who are tatlght about rhymning are more successful in reading (p. 35). In Nielsen and [Aletke-Stahlmrian (2002), we reportecc that a deaf child we studied f'romii preschool tlhrough elementary sclhool was confused initially abo)ut rhymling. She was of-ten overreliant on visual cues (e.g., claiming that the word Joot rhylmiecd with toot), btut later clevelopecl segmenting and blending abilities and Was able to use sound-symbol correspondences to decodel unknown worcls. Rhyminig is associated witlh phionological awareness at the onsetritme level, and niany researchers have founcl the ability to rhymiie to be a preclictor of reading achievement. Braclley and 13ryant (1983) andl Bryant, MacClean, Bradley, and Crossland (1990) found a causal link between rhyming andl reading, and other sttudies (e.g., Goswami & Mead, 1992) foundl that children relate rhytinig categories to spelling categories as they begin to read ancl spell. Phonological Awareness: The Link to Word Recognition 1le developpment of understanding antl the use of sound-to-print and printto-sound associations in spelling and decodling new words was thoroughly researched by Ehri (1980, 1991, 1995), who described several stages of word learning. She found that children first develop awareness at the word level, then at the syllable level, ancI finally at the phloneme level. Ehri (1980) and others (see review by Adams, 1990) found that as preschoolers and kindergartners experience print, they build an understanding of the orthography of words and begin to use this knowledge in conjunction with their knowledge of the linguistic properties of words. Beginning readers make sound-to-print and print-to-souncd connections and develop proficiency in unlocking tinknoxvn words (Juel, 1988; juel, Griffith, & Gough, 1986; Juel & Mincden-Cupp, 1999). They typically learn the soundto-letter connections for dominant sounds with single-letter matches (e.g., b, cd, and p). Shortly thereafter, beginning readers acquire an appreciation for blends (e.g., bl) and digraphs (e.g., th, sh). as well as an understanding of the multiple representations of vowel sounds (e.g., ai, ae, ai). Bv the middle to end of first grade, a stucdent wiho is engaged in age-appropriate reading tasks usually can spell simple shortvowel words. As childlren continue learning to read, they refine their comprehension of how the souncls of spoken words are mapped on to letters and letter combinations to create written worcds. Adams (1990) explained that studlents who learn to read and write in English must learn how the sounds of spoken English map on to letters and letter sequences within words. This knowledge is referred to as the alphabetic ptinciple, and involves the acquisition of an explicit awareness that vowels and letters from our alphabet form syllables, which in turn form words. However, the reading of English text is made difficult because each sound of the spoken language is not consistently represented by the same letter or group of letters. In learning to read an alphabetic script such as English, children mtist devote conscious attention to the manipulation of phonemes in words. Thus, as both Reid (1983) and Adams (1990) made clear, children must learn that in English, in addition to basic sound-to-letter knowledge, a given letter may function as a part of a group (e.g., c, b, versus ch) and that individual letters and groups of letters may have more than one sound, clepending on the position and sounds of neigh- L--VOI.UME 147, No. 3, 2002 AMERICAN ANNALS ODFTHE D1EAF 4o : boring letters (e.g., cap, cape, canal, tail). The ability to "sound out" (segment and blend) in order to unlock unknown words is a critical word-recognition strategy and is clearly tied to phonemic awareness. It is developed by beginning reaclers, affects proficiencv in worct recognition, and continues to affect reading success as students move through the school years (Foorman, Francis, S. Shaywitz, B. Shaywitz, & Fletcher, 1997). In addition, Ehri (1995) found that beginning readers' progress accelerates once they move beyond a focus on inclividual sound/letter matches and the use of segmenting and blending as an exclusive clecoding strategy, to a focus on words' orthographic features, or 'chunks.' This transition becomes evidtent when readers begin to discern unknown worcls in text by making analogies between one word and another: for example, 'If I know cat, this must beflat." In this process, readers use their short-term memory, ancd skills of "word identification, classification, sequencing, ancd association" (Paul, 1998, p. 199). One can simulate this more efficient strategy for word recognition by considering that to read an unfamiliar name of a medication, an aclult does not "sound out" each letter (e.g., /R/, /e/', /s/, /t/, //o/, //r/, /I/,/l) but, rather, readIs "parts" of the word: /Rest/, /or/, /il/. Two decades ago, Quenin (1982) detected evidence of this "chunking" strategy in profoundly deaf readers. More recently, Transler, Leybaert, and Gombert (1999) confirmed this finding. There is a good chance that students who do not possess phonological awareness, a key to the development of efficient word recognition skills, as well as age-appropriate English vocabulary and grammar abilities, will experience difficulty with reading, writing, and spelling in the elementary grades, especially with expository text (Snow et al., 1998). This is in part because decoding facilitates comprehension and comprehension facilitates decoding (Adams, 1990). VOUM VOLUME 147, No. 3, 2002 A Review of Research on Phonological Awareness and Deafness Ling, as reported by Waters and Doehring (1990), arguedl that while deaf children do not lave complete access to auclitory information. they seem able to use somc cues clerived from speechreading, "reiidual hearing, andl/or articulatory train ng to discover the relationship between spelling and sounds of English, and that this information could he used in reading individual words" (p. 331). Similarly, Hanson (1991) explained that although the development of phonological awareness may be delayecl when children are deaf, it still resembles that of hearing peers (see also Hanson & Fowler, 1987; 1P.Miller, 1997). Hlowever, Dodd (1974, 1)80) cautioned that cleaf students' phonological awareness is likely to be underspecified, because not all of the phonetic distinctions heard by a hearing student can be perceived by a deaf studeont. In the following sections of the present article we review much of the available reseai'ch on phonological awareness and deafness, grouping it uncer three headings: general phonological awareness research, phonological awareness and hearing acuity, and phonological awareness and speech articulation ability. General Phonological Awareness Research. "Deafness per se does not preclude the development of phonological representation" (Leybaert & Charlier, 1996, p. 235). As early as 1970, researchers discovered a relationship between phonological awareness and reading in deaf children (Conrad, 1970; J. Locke & V. Locke, 1971; Sallop, 1973). Almost a dozen individual researchers or research teams documented empirically that profoundly deaf children who read better than other deaf readers have phonological awareness (Bebko, 1998; Campbell, 1992; Fleetwood & Metzger, 1998; Hanson, 1989; Harris & Beech, 1998; Kelly, 1996; Leybaert & Alegria, 1995; Leybaert & Charlier, 1996; Licht- enstein, 1998; Marschark, 1993; Schaper & Reitsma. 1993). Extensive research reviews completecd by deaf educators, such as those by King and Quigley (1985), Paul and Jackson (1993), Mayer and Wells (1996), and Paul (1998), as well as our own more recent review (Nielsen & LuetkeStahlman. 2002), concluded that phonological awareness is an important factor to consider when planning reading instruction for deaf students. Paul (1998) thoroughly reviewed the available empirical evidence regarding reading and deafness, bilingualism, and general education, and concluded that development of both (a) phonological awareness and (b) proficiency in comprehending and expressing English vocabulary and grammar are required if deaf children are to readl as well as their hearing peers. Paul concluded that deaf children shoulcl receive phonics instruction. PhonologicalAwareness and HearingAcuity. Stuclies by several researchers across 3 decades documented that the hearing acuity of deaf readers correlates with phonological awareness (Becker, as cited in D. Wood & H. Wood, 1992; Conrad, 1970, 1973, 1979; Hanson, 1991; Harris & Beech, 1998; Leybaert & Alegria, 1995; P. Miller, 1997). Yet, the aided hearing acuity of participating subjects was seldom reported, and was unanalyzed except in studies by Luetke-Stahlman (1988), Moores et al. (1987), and Moores and Sweet (1991). Likewise, the effects of digital hearing aids, cochlear implants, or FM systems on the acquisition and use of phonological awareness have seldom been analyzed. PhonologicalAwareness and Speech ArticulationAbility. Waters and Doehring (1990) used two simplified phonics tasks to tap phono- 17N.3.20AMRANANLOFTEDF AMER[(--,AN ANNALS OF THE DEAF PHONOLOGICAL AWARENESS logical awareness and its relationship to reading and deafness. One required children to decicle if strings of letters were plausible comrbinations; the other, if words were real. The study showecl that speech intelligibility and Englishlanguage skills correlated with reading achievement. Phonological awareness correlated with reading achievement in studies by Conrad (1970), J. Locke and V. Locke (1971), and Reynolds (1986). However, Adams (1990) reviewecl the reading research and determined that simply teaching children to pronounce words does not call enoughi attention to the inclividual phonemes that constitute them. Yet, phonemes may receive sufficient attention in deaf edtication programs because most young deaf children receive speech-articulation therapy, during which words are often reducedl to series of phonemes so that their pronunciation can be practiced, and then blended together again into the original word. Thus, even if a (leaf student cannot hear speech, that student might "learn about ph)onology from motor events involving speech production" (1Hlanson, 1989, p. 73), through visual and tactile explanations during speech therapy, or from speechreading. Indeed, Marschark (1993) found that speech articulation and phonological awareness ahility correlated with reading proficiency when stuclents were deaf or hard of hearing. Other studies showing a correlation between phonological awareness and speech articulation, speech movement, kinesthetic sensations, or speech training were conducted in the 1980s and 1990s (Campbell & Wright, 1988; Hanson, 1986; Hanson & Fowler, 1987; Harris & Beech, 1998; Leybaert & Alegria, 1995; P. Miller, 1997:). We have suggested (Nielsen & LuetkeStahlman, 2002) that whien speechlanguage pathologists work with deaf children, the skills that are practiced will support reading development if the words' spelling is written out and discussed in conjunction witlh the words' articulation. Vo()UME 147, No. 3, 2002 The Assessment of Phonological Awareness blending to discern unknown words, a skill that evinces the employment of A reading program fora deaf sttident shouldl be hased on assessed literacy skills, including phonological awareness. When this occurs, knowlecdge of' undeveloped or undercdeveloped phonological awareness subskills for a particular chilcl can be idlentified by means of both formal and informal evaluation tools. In this section of the present article, we suggest several possible phonological awareness tests. (See Nielsen and Luetke-Stahlmain, 2002, for suggestecl measures for evaluating otlher reading skills areas.) If' educational teanm members expressed ain interest in knowing how well a deaf studlelnt was ahle to manipulate plhonemes relative to other cleaf studcents, they might elect to use a lormatl evaluation tool that had been standardizedl with deaf chilclren. Hlowever, literacy measures such as the 'I'est of Syntactic Abilities (QQuigley, Steinkamp, Power, Montanelli, & jones, 1978) and the Stanford AchievementTfest (adaptecl version, Trybus & Karachmer, 1977), a cotmnonly used instrument clesigned for the testing of cleaf children, do not include subtests for the evaluation of phonological awareness. TI'herefore, we recommend such standardized measures as the Phonological Awareness Test (Robertson & Sattler, 1997), which phonemic awareness. Informal assessment also could be includes subtests for segmentation, blending, substitution, rhyming, isolation, and cdeletion-skills that have been founcd to correlate empirically with reacling. The word attack subtest of the Woodcock Reading Mastery Test, or WRM (Woodcock, 1998), is popular among special edlucators, but the measure is a decoding task, not a phlonological awareness task. The word attack subtest requires that children pronounce nonsense words of one to four syllables (e.g., dcee, whie, than't, gaked, mnonglusta te-r). Not only is this subtest not a measure of phonological awareness, but a deaf student with poor speech intelligibility may be unable to pronounce the nonsense words ancl yet be capable of segmenting and used to address the questions asked by edlucational team members. Adams, Foormiian, Lundberg, and Beeler (1998), Ericson and Juliebo (1998), and Zgonc (2000) offer examples of products that provide informal measures of phonological awareness skills. Facilitating the Development of Phonological Awareness According to Paul (1998), word identification, in which a reader graclually becomes aware of the concept, pronunciation, cue, or sign for an unknown word, "is the foundation of the literacy process" (p. 34). Researchers have found that stLdents whio have acquired phonological awareness have an advantage in being able to unlock unknown words. In addition, when children are trained in the subskills of phonological awareness, most attain higher levels of reacling achievement (see reviews by Bryen & Gerber, 1987: National Reading Panel, 2000; Snow et al., 1998). Experimental, longitudinal, and case studies have demonstrated that phonological awareness can be taught (Bradley & Bryant, 1983; Lundberg, Frost, & Peterson, 1988; Nielsen & Luetke-Stahlman, 2002; Perfetti et al., 1987; Strassman, 1997). This was clearly the finding of two recent meta-analyses of the phonemic training research (J. Miller, 1999; National Reading Panel, 2000). Also, Adams (1990) and Snow et al. (1998) have advocated that if a child lacks phonological awareness, it must be taught to that child. tJsing gamelike activities, Lundberg et al. (1988) worked with preschool children to stimulate them to attend to the phonological structure of language. Analysis of the effect of this training on reading and spelling achievement in grades 1 and 2 showed small but significant differences between trained and untrained children on tasks in- AMERIC-AN ANNALS OF TIHE DEAF volving rhyming and worcd and syllable manipulation. However, the effect of phoneme segmentation ability on reading and spelling achievement through second grade was "dramatic" (p. 263). Luncdberg et al. concluded that explicit instruction, particularly at the phoneme level, "seems to he required" (p. 263) if there is to be an impact on later reading and spelling achievement. When providing training in phonemic awareness, Fox and Routh (as reported in Copeland et al., 1994) found that both training and practice in segmenting ancd blending assisted kindergarten children on "tasks analogous to reading" (p. 32). That is, "training of only segmenting without blending is insufficient" (p. 32). In addition, when letters were included, sound-to-letter manipulation was found to be more effective than sound manipulation alone (Adams, 1990; Miller, 1999; National Reading Panel, 2000). Finally, the key finding of the National Reading Panel's meta-analysis of 52 studies on phonemic awareness (2000) was that teaching phonemic awareness 'helps many different students learn to read," including 'children from various SES [socioeconomic status] levels," 'beginners who are low in PA [phonemic awareness] and thus at risk for developing reading problems in the future," and older disabled readers who have already developed reading problems" (p. 2-41). Paul (1998) agreed that, based on repeated reviews of the literacy and deafness research over the decades, instruction ancl practice involving the discrimination and identification of sounds in relation to print should be provided to deaf children. The first explicit training in phonological awareness and phonics (sound/ letters associations) with deaf children was probably conducted by Becker (as cited in D. Wood & H. Wood, 1992). Becker identified five children who read below grade level. They were fitted with appropriate amplification and given training at the phonemic level. They subsequently improved in their ability to identify sound/letter units, and VOLUME 3. 2002 No. 147, VOLUME 147, No. 3, 2002 transferred this knowle(ige to the reading of single words ancl conected text. Wandel (1989) found that Cued Speech facilitated the acquisition of phonemic awareness by making phonemes visually explicit. Her research showed that there was no difference in the reading scores of hearing and profoundly deaf students exposed to Cued Speech as assessed by the Stanford Achievement Test. Alegria, Dejean, Capouillez, and Leybaert (1990) found that Cued Speech assisted deaf students in decoding unknown words while reading. Both Quenin (1982) and LaSasso and Metzger (1998) found that Cued Speech manual cues facilitatec phonological awareness. Another system that makes phonemes explicit but also cues the sound/ letter match is Visual Phonics. This system is used with deaf children in the model elementary schcol on the Gallaudet tUniversity campus in Washington, DC (Marshall, Nussbaum, & WaddySmith, 1999), the Illinois State School for the Deaf, and in public school programs for deaf students in Arizona, Kansas, and Texas (see, e.g., Zaccagnini & Antia, 1993). Use of Cued Speech and Visual Phonics occurs in classrooms in which students are orally educated, as well as those in which signs are paired with speech (Marshall et al., 1999; Zaccagnini & Antii, 1993). More information and researcoI on both systems can be found on the Internet. Marschark (1993) suggested that phonological awareness training for deaf students should be multidimensional, involving sound-to-grapheme skills, articulation-to-spelling skills, speechreading-to-spelling skills, and the writing of grammatically correct English words, phrases, and sentences. Annual standardized da:a from a longitudinal study revealed that the reading ability of one deaf child improved dramatically (i.e., to grade level) when phonological awareness abilities, in conjunction with English vocabulary and grammatical language skills, were taught from preschool to sixth grade (Nielsen & Luetke-Stahlman, 2002). Suggestions for such activit. ies can be found in Nielsen and Luetke--Stahlman (2002) or can be adapted from resources typically used wh en in the teaching of hearing childre n (Adams et al., 1998; Ericson & Julie tbo, 1998; Fitzpatrick, 1997; Zgonc, 20( 00). Conclusion On January 8, 2002, President George W. Bush signed into law the No Child Left Behind Act of 2001. In a press release issued that day Secretary of Education Rod Paige stated, "A year ago, President Bush set out to improve every public school in this country-to ensure that students of all races, all abilities, and all ages receive the education they need and deserve.... Today, with the stroke of his pen, President Bush changed the culture of education in America and kept his promise to leave no child behind" (U1.S. Department of Education, 2002). The act is clear in directing that all children be taught using research-based methods. The research clearly calls for attention to the role of phonological awareness in giving deaf children the tools to break the code and to develop efficient word-recognition strategies. It is up to the profession to ensure that no deaf child is left behind. References Adams, M. (1990). Beginning to read: Thinking and learning about print. Cambridge. MA: MIT Press. Adams, M..
