Kindergarten Writing Running head: KINDERGARTEN WRITING & GRADE 1 LITERACY On the Contribution of Kindergarten Writing to Grade 1 Literacy: A Longitudinal Study in Hebrew Evelyn Shatil and David L. Share University of Haifa Iris Levin Tel-Aviv University Applied Psycholinguistics, 21, 2000, (1-21). 1 Kindergarten Writing 2 Abstract This longitudinal study examined the relationship between kindergarten word writing and Grade 1 literacy in a large sample of Israeli children. At kindergarten, a majority of children produced writing which displayed most of the grapho-spatial characteristics of conventional word-writing, although only one third of the children demonstrated a working knowledge of the alphabetic principle. Kindergarten writing significantly predicted variance in all three measures of Grade 1 literacy (decoding, spelling, and reading comprehension), even after controlling for general intelligence. We also investigated the role of alphabetic skills and socioliteracy variables in accounting for the predictive power of kindergarten writing. Kindergarten alphabetic skills (phonemic awareness and knowledge of letter names), but not socioliteracy factors (parental print exposure, parents’ reading to child, and Clay’s Concepts about Print), explained all the variance contributed by kindergarten writing to Grade 1 decoding and spelling. In the case of reading comprehension, both alphabetic and socioliteracy variables were able to account for the predictive power of kindergarten writing. As a precursor of reading comprehension, kindergarten writing appears to reflect both domain-specific alphabetic skills and broader socioliteracy factors underlying higher-order cognitive competencies essential for comprehending text. Kindergarten Writing 3 On the Contribution of Kindergarten Writing to Grade 1 Literacy: A Longitudinal Study in Hebrew Many kindergarten children spontaneously engage in writing prior to school entry (Bissex, 1980; Durkin, 1966; Ferreiro & Teberosky, 1982; Read, 1971;1986). These written productions are often classified into developmental scales with many features in common across different languages and orthographies (Ferreiro, 1990; Gombert & Fayol, 1992; Levin, Korat, & Amsterdamer, 1996; Pontecorvo & Zucchermaglio, 1990). Most scales include an early form of writing, prior to letters, described as scribbles, pseudoletters or mock letters. Next, writing appears as a string of random letters primarily consisting of the letters in the child’s name but unrelated to the target utterance. Finally, writing is determined by lettersound associations often called invented or creative spelling (Morris & Perney, 1984; Read 1971;1986). Although it is widely assumed that kindergarten writing lays the foundation for future literacy as conventionally defined in school-based reading and writing, the research literature on kindergarteners’ identification of environmental print shows that the connection between kindergarten competencies and formal school-based literacy cannot be taken for granted. For example, the observation that most kindergarten children are able to identify many labels, logos and signs appearing in their everyday environment (Goodall, 1984; Harste, Burke, & Woodward, 1982; Heibert, 1978; Kuby, Aldridge & Snyder, 1994; Masonheimer, Drum & Ehri, 1984; McGee, Lomax, & Head, 1988) is often interpreted as a child’s essential first steps toward literacy (e.g., Goodman & Goodman, 1979; Harste et al., 1982; Smith, 1976). However, most studies of environment print (e.g. Goodall, 1984; Heibert, 1978; Kuby et al., 1994; Masonheimer et al., 1984) have not found strong links between environmental print reading and conventional word identification. Kindergarten Writing 4 Similarly, in the case of writing, it cannot be assumed a priori that kindergarten writing is a precursor of formal literacy. This issue can only be resolved empirically. Although only a handful of studies have directly examined this issue, results consistently point to the conclusion that early attempts at writing are not merely a developmental curiosity but important precursors of mature literacy skills. Morris and Perney (1984) examined the relationship between spelling at the beginning of Grade 1 and both word recognition and reading comprehension at the end of Grade 1 in a sample of 75 children. The spelling test was preceded by a sample item in which the teacher modeled the sounding-out and spelling of a sample word (MAT). Children’s productions were classified on a 5-point developmental scale from pre-phonetic random letters, partial phonetic, fully phonetic, transitional, and orthographically correct spellings. Spelling at the beginning of Grade 1 was found to correlate .68 with end-of-year word recognition and .61 with reading comprehension. Ferroli and Shanahan (1987) also found a strong correlation between performance on a spelling test administered in Kindergarten and Grade 1 reading ability (r = .63) in a sample of 35 children. This result must be qualified, however, by the fact that children in this study were trained to listen for letter names and prompted to spell the words prior to the administration of the spelling test, hence scores obtained may possibly reflect a specific training effect or even general responsiveness to formal instruction rather than the children’s pre-existing ability to write. Mann, Tobin and Wilson (1987) correlated performance on a spelling test administered midway through Kindergarten with word identification and word attack a year later, midway through Grade 1 in a small sample of children (n=29). The predictive value of the spelling test was compared to a non-linguistic graphomotor test (the Harris Draw-a-Man Test). The phonological accuracy of spellings in Kindergarten correlated .48 with first grade word identification and .59 with word attack. Neither letter reversals nor Draw-a-Man performance correlated significantly with Grade 1 Kindergarten Writing 5 reading, suggesting that the association between kindergarten spelling and later reading is not due to grapho-motor control, attention or motivation. A second study by Mann et al. sought to shed light on the underlying abilities tapped by the invented spellings test. In addition to a test of invented spelling, a battery of linguistic and non-linguistic measures were administered to 22 children midway through Kindergarten. Significant positive correlations were found between the phonological accuracy of spellings and the tendency to classify spoken nonsense syllables according to common phonemes (as opposed to overall featural similarity) (r = .45), relative clause comprehension, but not between Kindergarten spellings and visual classification, Draw-a-Man scores or letter reversals. In a follow-up study, Mann (1993) examined the predictive validity of the phonological accuracy of invented spellings at the end of the Kindergarten year in a larger sample of 100 children, 79 of whom were retested on word identification and word attack one year later in Grade 1. Kindergarten spelling performance correlated .58 and .54 with word identification and word attack respectively. These results are all consistent with the position that early writing is important for the development of later reading ability, although this conclusion must be tempered by the fact that some of these studies were conducted on relatively small and/or homogeneous samples, while others included explicit training or demonstration that may have induced children to adopt strategies that may not normally be employed. The purpose of our study was twofold. First, we sought cross-linguistic confirmation of the predictive relationship between kindergarten writing and later school literacy. Our second aim was to elucidate the nature of this contribution in the light of current conceptualizations of literacy development which suggest at least two alternative hypotheses regarding the source of this relationship. Kindergarten Writing 6 One model of literacy development emphasizes the role of socio-cultural variables in the emergence of reading and writing skills. For example, movement into the early stages of writing development is assumed to develop as a result of experience with adults’ scaffolding and modeling in a variety of literate adult-child interactions such as storybook reading (Bus & van IJzendoorn, 1995; Clay, 1985; Teale & Sulzby, 1989), and also as a result of acquiring a sense of the function and purposes of print (Sulzby, Teale, & Kamberelis,1989). Thus, kindergarten writing may reflect the effect of socio-cultural variables such as quality and frequency of encounters with print, home-educational environment, and familial or communal expectations. Because kindergarten writing is believed to develop as a result of environmentally-driven spontaneous experimentation with print, it may be a form of social behavior acquired through a variety of culturally meaningful interactions. According to this view, kindergarten writing indirectly taps individual differences in pragmatic knowledge of the functions, purposes and settings of print. Alternatively, a cognitive information processing analysis suggests that the contribution of kindergarten writing to Grade 1 reading and spelling may reflect the operationalization of the alphabetic principle because writing involves two basic components; isolating sounds and selecting corresponding graphemes. Thus, specific alphabetic skills such as phonological awareness and knowledge of print-to-sound relationships may the source of kindergarten writing's predictive power. Indeed, many researchers investigating the invented spellings of kindergarten children have interpreted spellings as a reflection of phonemic awareness (see, e.g., Chomsky, 1979; Mann, 1993; Mann et al., 1987; Morris & Perney, 1984; Read, 1971;1986). Empirical support for this view can be found in Liberman, Rubin, Duques, and Carlisle (1985) who reported that a phoneme segmentation task accounted for 67% of invented spelling performance in a small group of Kindergarten children. The ability to write letters to spoken phonemes (a measure of phoneme-grapheme correspondence knowledge) Kindergarten Writing 7 accounted for an additional 20% of spelling variance. Mann (1993) also reported a strong correlation (r = .52) between phoneme segmentation scores and invented spelling in Kindergarten (n=100). More generally, an extensive research literature has demonstrated strong associations between kindergarten letter knowledge, phonological awareness and early reading (see Adams, 1990; Bryant & Bradley, 1985; Wagner & Torgesen, 1985), and Kindergarten letter naming and phonological awareness have also been shown to be strong predictors of Grade 1 writing ability (Berninger, 1992). Finally, a third possibility is that neither socioliteracy nor alphabetic variables separately suffice to explain the contribution of kindergarten writing to school-based literacy; only in conjunction is a complete account possible. That is, the kindergarten foundations of school-based literacy are laid only when specific alphabetic skills are engendered within socially meaningful contexts of literacy. By this account, the contribution of kindergarten writing to later literacy skills is explained as the joint product of both socioliteracy and alphabetic variables. We tested these hypotheses in a longitudinal study of a large representative sample of Hebrew-speaking children. Some preliminary comments are, therefore, required regarding the unique characteristics of Hebrew orthography (for further details, the reader is referred to either Frost and Bentin (1992), Shimron, (1993), or Share and Levin, (1999). Hebrew orthography is a primarily consonantal alphabet that exists in both pointed and unpointed forms. Unpointed script is partly voweled by means of the so-called “mothers of reading”; four consonantal letters ( )א ה ו יfunction both as vowels as well as consonants. This system, however, is both inconsistent and incomplete (Levin, Ravid, & Rapaport, 1998). Standard printed Hebrew appearing in today’s books, newspapers and magazines is unpointed. Pointed Hebrew employs diacritical marks or points (nekudot) and is used in texts intended for young children, in poetry and in sacred texts. In contrast to the mothers of Kindergarten Writing 8 reading, the diacritical system provides a complete and virtually unambiguous representation of the vowels by means of tiny dots and dashes appearing mostly under, but sometimes also above and between the letters. Children learn to read in pointed Hebrew, which has nearperfect one-to-one grapheme-to-phoneme correspondence (Navon & Shimron, 1984). Phoneme-to-grapheme relationships in both pointed and unpointed script, however, are frequently variable, with a number of pairs of (once phonemically distinct) consonant letters now representing the same phoneme. The vast majority of Hebrew words, therefore, contain phonemes which could be spelled with alternate letters. As the name square alphabet suggests, Hebrew letter architecture, relatively to the Latin alphabet, is more uniformly block-like with more horizontal and vertical strokes and fewer curves and diagonals. Not only are letters less distinctive, but word length and word shape are also relatively uniform. The following is a typical line of pointed Hebrew script and is read from right to left. .דומים ל ְִמחָ ִטים ִ עֵ ץ יער שֶ הֶ עָ לִים שֶ לו:א ֵֹרן )Oren: Ets ya’ar she’haelim shelo domim limechatim.) (Pine tree: A forest tree with leaves that resemble needles.) Although most children attain proficiency in decoding pointed text within their first year at school (Share & Levin, 1999), orthographically accurate spelling requires many years to achieve mastery, with spelling errors evident even among literate adults, as in English. To return to the primary goals of our study, we sought to confirm the longitudinal relationship between kindergarten writing and Grade 1 literacy and also extend this finding beyond the English language. We also hoped to shed light on some of the factors underlying the relationship between kindergarten writing and in-school literacy. Kindergarten Writing 9 Method Participants Three hundred and forty nine children attending 20 kindergartens in and around Haifa participated in this study. These kindergartens were selected so as to represent a wide range of socio-economic backgrounds. At the start of kindergarten testing, the total sample consisted of 173 boys and 176 girls, with a mean age of 6:0 years (sd: 4.2 months) and range 5:5 to 7:2 years. By the end of Grade 1, 32 children had either left the district or been retained in kindergarten. This left a total of 317 children who, at this time, attended 14 Grade 1 classes in five schools. Both Kindergarten and Grade 1 testing took place in the months of May and June. Measures Measures of kindergarten writing, alphabetic skills, socioliteracy variables and general ability were all administered individually at the end of the kindergarten school year. Testing was carried out by personnel trained in the fields of education, testing and/or psychology. Kindergarten and Grade 1 literacy instruction in Israel. In Israeli kindergartens, children write their own names on their artwork and recognize their names printed at fixed sites such as clothes’ hooks and personal lockers. Lists of letters as well as magnetic letters, printed words and texts are displayed around the room. Children are frequently read to from storybooks, view TV programs based on storybooks and voluntarily browse in books. Games that are aimed at promoting phonological awareness prevail, such as segmenting words into syllables, counting syllables and rhyming. Also commonplace are work sheets training visual discrimination (including letter discrimination) Kindergarten Writing 10 and letter copying. Invented spelling and grapho-phonemic awareness are encouraged in some kindergartens, but not in all. Little is devoted to alphabet recitation or letter naming. Formal instruction in reading and writing begins on entry to school at the age of six to seven years. Children learn to read pointed Hebrew which has near-perfect one-to-one lettersound correspondence. Decoding is usually mastered by the end of Grade 1 (see Share & Levin, 1999) at which point the curriculum shifts from a learning-to-read to a reading-to-learn mode. Most Israeli schools employ one of a number of structured basal series (often supplemented with a variety of materials) which all tend to be phonics-oriented. (For further details on reading instruction in Israel see Feitelson, 1989.) Kindergarten Writing Adopting the methodology previously employed by Levin and her colleagues (Levin et al., 1996; Levin & Korat, 1993; Levin & Tolchinsky-Landsmann, 1989; TolchinskyLandsmann & Levin, 1985; 1987), we encouraged children to write three pairs of dictated words as best as they could, with no demonstration or training provided. These pairs were selected to evaluate the ability to represent various aspects of writing. The first pair ‘elephantant’ (pil-nemala) contrasted both size of referent and phonological length (Ferreiro & Terebosky, 1979; Levin & Korat, 1993; Levin & Tolchinsky-Landsmann, 1989). The second pair ‘to place - a dress’ (lasim-simla) involved two words composed of the same syllables arranged in reverse order (Gombert & Fayol, 1992; Tolchinsky-Landsmann & Levin, 1987). The third, ‘book - story’ (sefer-sipur) involved two derivations of the same (tri-consonantal) root (Levin & Korat, 1993; Levin et al., 1996) . The writings produced were used to construct a kindergarten developmental writing scale. The Kindergarten Writing Scale Kindergarten Writing 11 Fourteen children were absent on the day of testing or refused to write. Twenty-nine additional children who drew instead of writing were excluded from the study as their motive for drawing was unclear: Some children may prefer to draw rather than produce unsatisfactory spellings while others may truly lack print-related knowledge. The spellings of the remaining 306 subjects were analyzed and classified according to a scale representing the major psycholinguistic phases in the development of writing. This scale included three broad categories; graphic-symbolic signs, random Hebrew letters and phonetic-consonantal representations. For each main writing category finer subdivisions were identified, creating a scale with a total of thirteen levels. The following is an abridged description of the scale. For samples of children’s productions and for a more detailed account of this scale, see Levin et al. (1996). Category I: Graphic-symbolic Signs The children in this general category produced two kinds of non-Hebrew signs: pseudowriting and a combination of symbols from various graphic systems. Pseudowriting (level 1). The children in this category produced unidentifiable signs which were reminiscent of basic letter forms. Productions contained a limited number of intersecting lines and angles per sign, linear arrangement of the signs and, in most cases, a limited number of signs for each attempted spelling. Mixed graphic-symbolic systems (level 2). The children in this group used recognizable signs from various symbolic systems such as the number system and the Latin alphabet as well as Hebrew letters. Category II: Random Hebrew Letters The children in this group produced identifiable Hebrew letters and only Hebrew letters. These letters, however, did not match the sounds in the words. Category II spellings were scored so as to reflect the diversity (low, medium, high) of a child’s repertoire of letters. Kindergarten Writing 12 The child’s score was the number of different letters as a proportion of the total number of letters s/he produced. The children in levels 3, 4 and 5 produced spellings in which up to 30% (level 3), 31% to 40% (level 4) and at least 41% (level 5) of the letters produced had different identities. Category III: Consonantal Representations Category III productions matched at least part of the word’s consonantal structure. However, because this ability varied widely, children in this category were assigned to one of three different levels; elementary, intermediate and advanced consonantal representation. At all three levels, either correct letters or homophonic equivalents were taken as acceptable spellings. At the intermediate and advanced levels, there were some children who attempted to represent vowel information as well. For these children, the scores assigned also reflected competence at vowel representation (none, low, intermediate or advanced). Elementary consonantal representation (level 6). Children in this group successfully transcribed at least one third of the required consonant phonemes. The remaining letters produced by these children appeared to be random letters unrelated to the remaining consonantal phonemes in the words. There was no vowel representation in this group. Intermediate consonantal representation (levels 7,8 and 9). Children in this group successfully transcribed at least half of the required consonant phonemes. The remaining consonants were for the most part phonetically close, i.e. /ts/ for /s/ or /b/ for /p/ and (much less frequently) random letters. Children were assigned to levels 7, 8, and 9 according to their ability to represent vowels; no representation, elementary or intermediate vowel representation respectively. Advanced consonantal representation (levels 10 to 13). These productions successfully transcribed all of the required consonant phonemes. Children in this category were assigned to one of four levels. Levels 10 to 13 referred to lack of vowel representation, elementary, Kindergarten Writing 13 intermediate and advanced vowel representation respectively. No child in the sample produced perfectly accurate spellings of all words. Interjudge reliability was assessed by classification of 90 protocols by an independent judge, following instruction in using the scale. These protocols were randomly selected by taking approximately 25% of protocols from each category. The Pearson correlation between our classification and that of the independent judge was .96 (p < .001) indicating high reliability. Kindergarten General Intelligence To ensure that any relationship between kindergarten writing and Grade 1 literacy was not simply a product of general intelligence, we also evaluated both verbal and non-verbal intelligence. Colored Progressive Matrices (Raven, 1986, Sets A and B). Parts A and B were administered individually and scored as indicated in the author’s manual. Scores ranged from 1 to 23 (maximum = 24) with a mean of 9.8 (sd: 3.76). Peabody Picture Vocabulary Test. (Israeli adaptation, Nevo & Solberg, 1979). This test of receptive vocabulary was individually administered and scored as indicated in the test manual. Raw scores ranged from 19 to 66, with a mean of 50 (sd: 6.98). Kindergarten Alphabetic Variables This set of measures included letter-naming knowledge and three subtests of phonological awareness; initial consonant matching, phoneme blending and initial consonant isolation. Kindergarten Writing 14 Letter naming. The children were asked to name twelve printed letters. The raw number of letters named correctly was employed as a measure of letter naming. Test-retest reliability (3 weeks) was 0.82, n=34. Initial consonant matching. The children heard ten consecutive pairs of common mono-syllabic Hebrew words and were required to indicate whether the words started with the same “sound” (initial phoneme). (e.g. /cor/ (cold) and /ken/ (yes); or /ben/ (son) and /gil/ (age)). Testing was preceded by two examples, one pair with matching consonants, the second with non-matching consonants. Children were not required to name the initial phonemes only to make a yes/no judgment. Each child was tested individually. One point was allocated for each correct answer with a maximum possible score of 10. The mean was 6.0 (sd: 2.05). Testretest reliability (3 weeks) was .60, n=29. Phoneme blending. The children were required to blend two phonemes into a monosyllabic word. There were two sets of stimuli, each containing five items. Each set was preceded by an example. In the first set, each item included a vowel followed by a consonant. (e.g. /o/ and /r/ produced the word /or/ (light)). In the second set, each item contained a consonant followed by a vowel. For example, when blended, the sounds /l/ and /o/ produced the word /lo/ (no). The total score was simply the number of correct responses on the two sets of items. The mean was 4.3 (sd: 2.25). Test-retest reliability (3 weeks) was .66, n=34. Initial consonant isolation. The child heard sixteen monosyllabic (CVC) pseudowords (e.g. /mez/) and had to isolate the initial consonant (“beginning sound”) of each item. Prior to the test items, two items were demonstrated. Test-retest reliability (3 weeks) was 0.73, n=29. Kindergarten Socioliteracy Variables This set included measures of parental print exposure, parent-child story reading, and Clay's measure of a child’s concepts about print. Kindergarten Writing 15 Parent print exposure. Hebrew versions of the Author Recognition Test and the Magazine Recognition Test (Stanovich & West, 1989) were developed and administered to the children’s mothers. These tests assess familiarity with particular authors and magazines. Mothers received two lists; a list of 57 author names and another list of 57 magazine names. Twenty nine of the items in the author list were fictitious and 28 were the names of real authors. In the magazine list, 19 names were fictitious and 31 were real. The mothers were asked to indicate which names in the lists were names of real authors and/or magazines. To discourage guessing, the questionnaire explicitly stated that fictitious items had been inserted in the lists. Mothers were asked to work unassisted. For each questionnaire a score was obtained by subtracting the number of errors from the total number marked. A single parental print-exposure score was then formed by averaging the scores from both questionnaires. The mean score on this composite measure was 9.95 (sd: 5.42). Questionnaire return rate was 82%. Parents read to child. Information about the extent to which a child was read to at home during her/his last year of kindergarten, was obtained using a checklist question asking the children’s mothers how often the child had been read to/heard stories from parents or siblings while in kindergarten. Five response categories varied from many times (more than once a day) to seldom (less than once a week). Concepts about Print (SAND) (Clay, 1985). A Hebrew adaptation of this test (Wohl, 1986) required children to answer 16 questions on the functions and characteristics of print. The questions tested knowledge of such concepts as page, line, word, letter, writing, drawing, knowledge of book and text handling (for example, where one begins and ends reading a book, a page, a line) as well as the direction in which reading proceeds (from right to left in Hebrew). Two additional questions were developed which related to the child’s awareness of the presence, shape and location of Hebrew diacritical marks. It should be remarked that no Kindergarten Writing 16 item in this test tapped specific knowledge either of letter names or letter sounds. Test-retest reliability (2 weeks) was 0.81; n=27. Grade 1 Literacy Assessment The children’s performance on a number of literacy measures was assessed at the end of Grade 1 in a series of sessions each lasting approximately 30 minutes. Untimed oral word reading. A list of 114 words printed in pointed Hebrew was specially developed for this purpose. These items varied in degree of difficulty ranging from short monomorphemic items (e.g., /kar/ (cold) קרto longer, multimorphemic words (e.g., (their song) ָתם ָ מנגִ ינ, /manginatam/)(for further details, see Shatil, 1997). Scores ranged from 2 to 114, with a mean of 93.9 (sd: 25.98). Test-retest reliability (3 weeks) was .88, n=23. Timed oral word reading. A list of 56 words was specially developed to measure the number of words read in one minute. The words were arranged in clusters of four consecutive items, each cluster varying in degree of morphemic complexity and length, but not exceeding two syllables (e.g., monosyllabic; ( ָאבfather) /av/, disyllabic; בָ ָרד, (hail) /barad/). The spoken forms of the words in the list were considered familiar to most Israeli first graders (no up-todate frequency tables exist in Hebrew). Scores were calculated by subtracting the number of errors from the total number of words attempted in 60 seconds. Scores ranged from 1 to 54 words per minute, with a mean of 27.5 (sd: 12.61). Test-retest reliability (3 weeks) was .98 (n=24). Kindergarten Writing 17 A single composite word reading measure was computed by averaging Z scores for the timed and untimed word-reading measures. Composite scores ranged from -2.74 to 1.42 , with a mean of 0 and a standard deviation of .87. Grade 1 Reading Comprehension Sentence comprehension. Twenty-one vocabulary (word meaning) and comprehension questions were used to test the ability to understand factual, inferential and vocabulary information in sentences. The test was collectively administered in three separate whole-class sessions (seven sentences per session). All the questions were multiple-choice. (For example, “Dan wore a woolen hat, a coat, a scarf and a pair of gloves. It was 1. in the spring 2. in the summer 3. in the winter”). The sentence length varied from 3 to 36 words. One point was allocated for each correct answer. Scores ranged from 2 to 21, with a mean of 18 (sd: 2.79). Text comprehension: expository. A text dealing with bird migration was divided into four passages that varied in length from 19 to 25 words. Each passage was followed by a set of 5 to 7 true/false questions yielding a total of 24 questions. The children were tested collectively in class, in four different sessions and were required to read the passage, the questions, then circle the correct answer. Scores ranged from 7 to 24, with a mean of 18.3 (sd: 3.65). Text comprehension: narrative. A story about a boy and his dog was divided into four parts that varied in length from 44 to 49 words. Each part was followed by a set of 6 true/false questions, giving a total of 24 test items. The children were also required to read two short passages, each followed by five multiple choice questions. One passage described a birthday party and the other a "Feast of Lots" celebration. The administration and scoring procedure were the same as for the expository text. Together there were a total of 34 questions. Scores ranged from 13 to 33, with a mean of 26.2 (sd: 4.31). Kindergarten Writing 18 A composite reading comprehension score was formed by summing the children’s raw scores. The minimum and maximum composite scores were 34 and 77, with a mean of 62.7 (sd: 9.02) Grade 1 Spelling Regular dictation. Children were required to spell 20 very common words (e.g., ֶילֶד child /yeled/) dictated by the experimenter. The test was collectively administered to whole classes. The words were pronounced one at a time and each word was repeated twice. For each child two scores were computed: a consonant score and a vowel score. Each word was scored separately and one point was allotted for each complete and correct consonantal letterstring (e.g. “y-l-d” for “yeled”). Each vowel phoneme sound, however, was scored separately; three points were given for each correct vowel (either vowel letter or vowel diacritic), two points for an incorrect vowel symbol but which correctly transcribed the vowel, and zero for entirely incorrect vowels (symbols which corresponded to a sound other than the target sound). Consonant scores ranged from 7 to 20 (maximum 20) with a mean of 15.0 (sd: 2.48). Vowel scores ranged from 46 to 90 (maximum 90), with a mean of 79.5 (sd: 6.91). Homophone dictation. This test consisted of 20 heterographic homophones. For example, /car/ spelled קרmeans ‘cold’ and /car/ spelled כרmeans ‘pillow’. Each target word was spoken three times: first alone, then in a sentence, then finally alone. Scores were computed by allocating one point for each correct target (homophonic) letter. Scores ranged from 0 to 20 with a mean of 11.7 (sd: 3.05). Orthographic choice. (After Olson, Kliegl, Davidson, & Foltz, 1985.) In this task, children are required to select the correct spelling when presented with both the correct spelling and an incorrect (homophonic) alternative. This test was given in a group setting with all 20 items read aloud by the tester. Scores ranged from 4 to 20, with a mean of 17.4 ( sd: 2.49). Kindergarten Writing 19 Homophone choice. The children were presented with 16 printed sentences each containing both members of a homophone pair. Each of the two spellings appeared side by side in the sentence and the child required to select the appropriate spelling. This test was also administered to whole classes with the experimenter reading aloud each sentence in turn. Scores ranged from 5 to 16, with a mean of 11.7 (sd: 2.55). A single composite spelling score was computed by transforming the four measures described above into Z-scores and then averaging. Composite scores ranged from -2.92 to 1.76, with a mean of 0.0 (sd: .76). UPTOHERE Results The distribution of scores along the kindergarten writing scale is displayed in Table 1. The data reveal that (with the possible exception of the 23 children who drew instead of writing) kindergarten children are capable of producing word-like arrays of letters or letterlike shapes when requested to write. Moreover, the majority (76%) of the children produced only forms which were clearly identifiable Hebrew letters. These findings are clear evidence that most children entering school can differentiate between the writing system and other graphic systems such as the numeric system (cf. Karmiloff-Smith & Tolchinsky-Landsmann, 1997). In addition, they know a good deal about the grapho-spatial characteristics of writing such as the distinctive features of letters, the horizontal serial ordering of letters in a word, and letter orientation. Table 1 demonstrates enormous variety in kindergarteners' writing. Some children drew (see above) while others produced symbolic-graphic signs, random Hebrew letters or readable, phonetically appropriate spellings: no one stage appears to be generally representative of the whole sample. However, the fact that 71% of the children in the sample are not reliably representing the sound structure of words when writing (the productions of Kindergarten Writing 20 215 subjects were classified as graphic-symbolic or random letter strings – categories I and II) suggests that for the majority of kindergarteners, writing is viewed at best as a sequential array of letter shapes or, at worst, as a highly specialized form of drawing. This is an important observation as it reflects the complexity inherent in the acquisition of alphabetic literacy: fewer than one third of the children in the sample demonstrated a working knowledge of the alphabetic principle as evident in Category III productions. To examine the link between kindergarten writing and Grade 1 literacy, the contribution of kindergarten writing was calculated after controlling for the variance associated with general intelligence. Separate regression analyses were carried out with Grade 1 decoding, spelling and reading comprehension as the criterion variables. Both measures of general intelligence, as assessed by the Raven and Peabody tests, were entered in a first step, and kindergarten writing at the second step (see Table 2). Table 2 shows that kindergarten writing is significantly correlated with all three Grade 1 literacy measures. Second, kindergarten writing contributes significant amounts of variance (7%, 11% and 8%) to decoding, spelling and reading comprehension respectively, after the variance due to general intelligence has been partialled out. Table 2 also shows that kindergarten writing was more strongly related to Grade 1 decoding and spelling than was intelligence. These results are important in that they confirm and extend the English-language findings indicating that children’s early attempts at writing are by no means inconsequential as regards individual differences in later school literacy. Kindergartners with more advanced knowledge of the writing system as witnessed in their writing become better spellers, decoders and comprehenders in Grade 1. Kindergarten Writing 21 Having confirmed that kindergarten writing is a significant precursor of Grade 1 literacy skills, even after controlling for general intelligence, we now turn to the second aim of our study -- to elucidate the nature of this contribution. Table 3 presents the means and standard deviations for the kindergarten alphabetic and socioliteracy variables as well as the concurrent correlations between these skills at kindergarten and the predictive correlations with later Grade 1 literacy. Initial examination of the predictive correlations (see lower panel of Table 3) reveals that, with minor exceptions, school literacy skills correlate significantly with all the kindergarten variables. Grade 1 decoding appears to be related both to kindergarten alphabetic skills (mean r = .26) and to socioliteracy variables (mean r = .19). Grade 1 spelling ability is also related to socioliteracy and to alphabetic variables (mean correlations are .33 and .27 respectively). The relatively large correlation between Grade 1 spelling and kindergarten letter naming (r = .48), suggests that early letter knowledge may be particularly important to the acquisition of later spelling ability. Reading comprehension is also significantly correlated with both socioliteracy variables (mean r = .44) and alphabetic skills (mean r = .36). The concurrent correlations between the alphabetic and socioliteracy variables at kindergarten show the variables within each set to be weakly intercorrelated. For the purposes of testing competing hypotheses it is important to note that these two sets of variables were not strongly correlated, and hence not statistically redundant. To test alternate hypotheses regarding the source of the predictive power of kindergarten writing, we undertook a series of hierarchical (setwise) multiple regression analyses with Grade 1 literacy measures as the criterion variables.1 As already indicated in Table 2, kindergarten writing explained 7%, 11%, and 8% of the variance of decoding, 1 In hierarchical setwise regression, groups of variables are entered simultaneously in a single step to determine the collective contribution of the set as a whole (see Cohen & Cohen, 1975). Kindergarten Writing 22 spelling and reading comprehension respectively when entered at step 2 after general intelligence. To determine to what extent these three variance contributions can be explained by either socioliteracy or alphabetic variables, we then examined the contribution of kindergarten writing at step 3 after entering the relevant set of socioliteracy or alphabetic variables at step 2. If the contribution of kindergarten writing to Grade 1 literacy can be attributed to socioliteracy variables, then kindergarten writing (step 3) should no longer account for significant Grade 1 literacy variance once socioliteracy variables are partialled out at step 2. Alternatively, if alphabetic skills alone explain why kindergarten writing predicts Grade 1 reading and spelling, there should be no unique variance contributed (at step 3) by kindergarten writing to Grade 1 literacy once alphabetic skills are partialled out at step 2. For ease of comparison, we have included the “simple” variance contributions of kindergarten writing (taken from Table 2) when entered at step 2 after general intelligence. Table 4 shows that alphabetic skills successfully explain the entire contribution of kindergarten writing to all three forms of Grade 1 literacy (decoding, spelling, and comprehension). In each case, kindergarten writing no longer accounted for significant variance in Grade 1 literacy measures after the contribution of alphabetic skills was included at step 2. On the other hand, socioliteracy variables fully explained only the contribution to reading comprehension. In the case of decoding and spelling, socioliteracy variables explained only around one half of the variance due to kindergarten writing (decoding: 4.0%/7.6%, spelling: 5.3%/11.0%). Overall, these findings suggest that the predictive power of the kindergarten writing task can be accounted for most parsimoniously by the child's alphabetic knowledge as reflected in phonological awareness and letter name knowledge rather than by socioliteracy factors. In the case of reading comprehension, on the other hand, both socioliteracy and alphabetic variables provided equally convincing explanations for the contribution of kindergarten writing. (Obviously, no additional analyses were needed (i.e., Kindergarten Writing 23 combining alphabetic and socioliteracy variables at step 2) since no variance was left to be explained). Discussion Examination of children’s written productions in Kindergarten revealed that most children were capable of producing writing which exhibits most of the grapho-spatial characteristics of conventional word-writing. A majority of this sample were even producing well-formed Hebrew letters. Thus, a major conclusion of the present study regards the cohort’s familiarity with the grapho-spatial aspects of writing as well as their ability to select the appropriate system from among the various symbolic systems available. The ability of so many children to draw a variety of Hebrew letters from memory implies that, by the end of kindergarten, visual and motor-kinesthetic memory for domain-specific symbolic materials appears to be well developed. A second major finding is that although the majority of children in this sample used letters or letter-like symbols when writing, most (approximately 70%) seemed unable to use letters to represent the sounds of words (or were even unaware that letters represent sounds). This suggests that the ability to segment words into phonemes, to recall the letters whose names and/or sounds match these phonemes and to reproduce these letter shapes on paper represents a formidable challenge for kindergarten children, indeed, one beyond the capabilities of a majority of this group. It would appear that some form of explicit instruction, whether formal or informal, is likely to be required before most children are able to accomplish such a demanding task. Two key findings emerged concerning the association between kindergarten writing and Grade 1 decoding and spelling. Kindergarten writing successfully predicted the ability to Kindergarten Writing 24 decode and to spell even after controlling for the contribution of general intelligence. In both cases, the unique variance explained was by no means inconsequential (7% and 11%). As such, kindergarten writing can be considered a bona fide precursor of later literacy development and not merely a developmental curiosity. Second, when alphabetic skills were entered after general intelligence, kindergarten writing no longer contributed significant variance to either Grade 1 decoding or spelling. This constitutes strong support for the view that the contribution of kindergarten writing to Grade 1 decoding and spelling can be interpreted as a reflection of a child's working knowledge of the alphabetic principle, i.e., awareness of the phonological units represented by letters and the associations between these spoken segments and the graphic symbols (Liberman et al., 1985; Mann, 1993; Mann et al., 1987; Morris & Perney, 1984; Read, 1971; 1986). In contrast, when socioliteracy variables were entered after general intelligence, they accounted for significant portions of the variance contributed by kindergarten writing to Grade 1 decoding and spelling but left nearly half of the original contribution unexplained. We conclude, therefore, that domain-specific alphabetic knowledge rather than socioliteracy factors provides the best explanation for the predictive power of kindergarten writing with regard to decoding and spelling. Alphabetic skills also fully accounted for the contribution of kindergarten writing to Grade 1 reading comprehension, but socioliteracy variables performed equally well. The latter finding is consistent with the view that kindergarten writing taps not only domain-specific alphabetic skills but also broader socioliteracy factors underlying higher-order linguistic and cognitive competencies essential for comprehending text. Also consistent with this account is the finding that IQ (assessed in this study by both verbal and non-verbal measures) contributed substantial and significant variance to both Grade 1 spelling and comprehension (8.5% and 19%) but only marginal variance (2.5%, p = .03) to decoding. This suggests that the process of spelling may demand a significant degree of monitoring and self-correction in the course of Kindergarten Writing 25 ongoing, self-initiated comparison of a written production with an intended target string (Lindamood, 1997). By this account, kindergarten writing may be tapping higher-order cognitive processes that are essential for comprehending text and not solely specific alphabetic knowledge. The fact that IQ has a negligible relationship with decoding skill provides strong support for the modularity of word recognition (Seidenberg, 1985; Stanovich, 1990; 1991). Whereas decoding may be fully “encapsulated”, spelling may be less cognitively autonomous. This study also shed light on the connection between kindergarten phonemic awareness and decoding. It appears that the association between the two may not be as strong in Hebrew as it is in English (cf. Share et al. 1984; Stanovich et al. 1984). There are at least two possible explanations for this result. First, we speculate that learning to decode pointed Hebrew may require less sophisticated phoneme manipulation skills compared to English. This is because pointed script is essentially a succession of a relatively limited number of simple CV segments and almost entirely lacks the complex consonant blends common to English (cf. Treiman, 1985) and which are likely to pose considerable demands on the ability to blend phonemes. An alternative explanation argues that the high degree of symbol-sound regularity in printed Hebrew accelerates acquisition of the code as in the case in other regular orthographies such as Italian and German (see Cossu, 1999, and Wimmer, 1999). By the end of Grade 1, when most Israeli children have mastered decoding, individual differences in phonemic skills may be less influential (see Share and Levin, 1999). Consistent with this account, Bentin, Hammer and Cahan (1991) found that the correlation between kindergarten phonemic awareness and Grade 1 decoding in Hebrew was significantly greater in the middle of Grade 1 (r = .55) than at the end of Grade 1 (r = .33). Prominent among the socioliteracy variables was Clay’s Print Concepts measure which correlated very strongly with reading comprehension (r = .58) . A similar coefficient (r Kindergarten Writing 26 = .56) was obtained between the Print Concepts test and reading comprehension by Tunmer, Herriman and Nesdale (1988). Moreover, using path analysis, Tunmer et al. (1988) found that Print Concepts was the only measure with a significant path coefficient in the prediction of reading comprehension. This task appears to be both a measure of the vocabulary of literacy and also of conceptual knowledge about print conventions. It would be of interest to carry out an experimental training study to determine whether teaching print concepts has a direct causal connection to reading comprehension, or is more a proxy for broader social and environmental factors underlying the acquisition of specific cognitive competencies. The present study clarifies the role of kindergarten writing in the development of literacy. Kindergarten writing is indeed a precursor of later decoding and spelling ability, not because of what the children seem to be doing when writing (producing arrays of letters and letter shapes to convey socially and culturally appropriate messages), but because of the usually covert, domain-specific knowledge about the relationships between letters and sounds they bring or fail to bring to the task. As a precursor of reading comprehension, kindergarten writing appears to reflect not only domain-specific alphabetic skills but also broader socioliteracy factors underlying higher-order cognitive competencies essential for comprehending text. This study suggests that there is much to be gained by encouraging kindergarteners to write (see also Levin, Ravid, & Rapaport, 1998; Snow, Burns, & Griffin, 1998). The cognitive and communicative challenge of putting words down on paper seems to engage not only higher-order conceptual and cognitive faculties important for later text comprehension (and, no doubt, production too) but also appears to be an excellent vehicle for developing a child’s working knowledge of the alphabetic principle.
