In 2 studies, we compared the effectiveness of 4 different methods for acquiring initial reading vocabulary. Training emphasized similarity of word beginnings (onset plus vowel), similarity of word endings (rimes), phoneme segmentation and blending, or simple repetition of whole words. These 4 training regimes were compared with a control group given only regular classroom instruction. Beginning nonreaders acquired the trained words fastest in the onset and rime conditions, and most slowly in the whole word condition. Retention was excellent after 1 week and after 4 to 6 months, with no differences due to method of acquisition when only children who met the learning criterion were considered. Generalization to reading new words and nonwords was 40% to 50% on the first encounter for all children who acquired the entire word set during learning. In Experiment 2, the same pattern of results was obtained for delayed readers in Grade 2.  相似文献

A frequency-based vocabulary of 17,602 words was compiled and analyzed in order to group words with recurring syllable and rime patterns for teaching reading. The role of the rime unit (e.g.,ite inkite andinvite) in determining vowel pronunciation was central to the analysis because of the difficulty that the ambiguity of English vowel spelling presents to children who do not learn to read words easily. Vowel pronunciation in each orthographic rime was examined, both for its consistency in all words in which the rime occurs and for regularity, defined as conformity to the most frequent pronunciation for each vowel spelling in each of six orthographic syllable types. Of the 824 different orthographic rimes, 616 occur in rime families as the building blocks of almost all the 43,041 syllables of the words. These rimes account for a striking amount of patterning in the orthography: 436 are both regular and consistent in pronunciation (except where a single exception word occurs); another 55 are consistent but not regular. Of the remaining 125, only 86 have less than a 90 percent level of consistency. The high order of congruence of orthographic and phonological rimes suggests their usefulness as units for teaching reading.  相似文献

ABSTRACT

As children learn to read, they become sensitive to context-dependent vowel pronunciations in words, considered a form of statistical learning. The work of Treiman and colleagues demonstrated that readers’ vowel pronunciations depend on the consonantal context in which the vowel occurs and reading experience. Using explanatory item-response models we examined child- and nonword-factors associated with children’s assignment of more versus less frequent grapheme-phoneme correspondences (GPC) to vowel pronunciations as a function of rime coda in monosyllabic nonwords. Students (N = 96) in grades 2-5 read nonwords in which more versus less frequent vowel GPCs were wholly supported or partially favored by the rime unit. Use of less frequent vowel GPCs was predicted by set for variability, word reading, and rime support for the context-dependent vowel pronunciation. We interpret the results within a developmental word reading model in which initially incomplete and oversimplified GPC representations become more context dependent with reading experience.  相似文献

We conducted two case studies to evaluate the effectiveness of individualized remedial reading instruction linked to direct measures of student learning and transfer. The participants were two first grade children at serious risk of reading failure. The instruction targeted decoding of one syllable short vowel words and first emphasized onset-rimes and then phoneme manipulation. Forty words organized into 10 rime patterns were targeted for instruction. Probes consisting of all the instructional words were administered before each instructional session to monitor student progress. We also administered transfer probes to determine if the children could apply their knowledge more broadly. Instruction with onset-rime units yielded excellent maintenance and near transfer (novel words containing instructed rimes) but not far transfer (novel words derived from uninstructed rimes). The instructional change to phoneme manipulation yielded better far transfer for one of the two children. We consider the importance of administering measures that assess more than what is taught to get an accurate portrait of children’s responsiveness to instruction.  相似文献

The effect of phonology and semantics on word learning in 5- and 6-year-old children was explored. In Experiment 1, children learned to read words varying in spelling-sound consistency and imageability. Consistency affected performance on early trials, whereas imageability affected performance on later trials. Individual differences among children in phonemic awareness on the trained words were related to learning, and knowledge of a word's meaning predicted how well it was learned. In Experiment 2, phonological and semantic knowledge of nonwords was manipulated prior to word learning. Familiarization with a word's pronunciation facilitated word learning, but there was no additional benefit from being taught to associate a meaning with a nonword.

This paper presents two experiments investigating 8–9 year old children's sensitivity to rime level sound-spelling correspondence units when spelling words and nonwords. In Experiment 1, children spelled more words correctly if they contained a common rime unit rather than a unique or irregular unit. In Experiment 2, children spelled more words and nonwords correctly if they had many rime unit neighbours; words and nonwords with average or few rime unit neighbours were spelled less well. These findings show that children's spelling can not be described simply according to one-to-one phoneme-grapheme mapping. Instead, children are sensitive to lexical factors such as rime unit sound-spelling correspondence. The findings are interpreted within the framework of a connectionist model of spelling development.  相似文献

The purpose of the experiments was to determine the automatic use of large or small word reading units in young readers in the absence of word decoding strategies. Picture-word Stroop interference was examined from four types of conflicting labels: (a) words containing both highly predictable grapheme–phoneme correspondence (GPC) units and highly consistent rime units (henceforth, Hi-GPC + Hi-Rime); (b) words with highly predictable GPC units and less consistent rime units (Hi-GPC + Lo-Rime); (c) words with low predictability GPC units and highly consistent rime units (Low GPC + High Rime); (d) nonwords that contained both highly predictable GPC and highly consistent rime units. Naming time for pictures containing these labels was compared against that for pictures with random letter strings or no labels. In Experiment 1, Stroop interference was examined in first, second, and third grade children to determine whether there was developmental change in the presence of rime or GPC interference. In Experiment 2, Stroop interference was examined as a function of relative reading skill in first grade children. In Experiment 3, Stroop interference in adults was compared to the use of rime or GPC pronunciation strategies for nonword reading. In all experiments, Stroop interference in picture naming was longer for pictures with highly predictable GPC unit labels than less predictable GPC unit labels. However, in Experiment 3, even though adults showed interference from predictable GPC units in the Stroop task, they always preferred rime pronunciation for ambiguous nonwords in the nonword reading task. It is argued that the current experiments provide evidence for a flexible units model. The results of this study were presented at the Cognitive Development Society meeting, November 2001, Virginia Beach, VA, and the American Educational Research Association meeting, April 2004, San Diego, California.  相似文献

Previous research has established that the degree of ‘wordlikeness’ of nonwords affects young children's nonword repetition performance. Experiment 1 examined the possibility that output processes are responsible for the wordlikeness effect by using a probed recall procedure. Wordlikeness was defined in terms of phonological neighbourhood density, although this measure was found to be related to the traditional measure of wordlikeness involving adult ratings. A significant effect of number of phonological neighbours/wordlikeness was observed in favour of nonwords with many neighbours. In Experiments 2 and 3 the wordlikeness effect was qualified by a significant interaction with nonword repetition ability. Children with poorer repetition ability were affected by number of neighbours/wordlikeness, while children with better repetition ability were not. Children with poorer repetition ability were significantly poorer than the better repeaters with nonwords with few neighbours. The results were interpreted in terms of theories of phonological development that suggest progressive segmentation of lexical representations. In Experiment 4 the relationship of children's nonword repetition ability to phonemic discrimination ability was investigated. The results demonstrated that children with better nonword repetition ability had superior phonemic discrimination performance than children with poorer nonword repetition ability.  相似文献

Three experiments were undertaken to examinesecond and fifth grade Telugu-speaking children's awareness of phonological andorthographic properties of familiar Teluguwords. Experiment 1 focused on the strategies thechildren used in completing word fragments.Experiment 2 examined the children's ability tojudge and generate rhyming words, and Experiment 3examined the children's strategies incomprehending meanings of orthographicallysimilar rhyming vs. non-rhyming word pairs in asentence completion task. The results demonstrated that specific features ofsemi-syllabic alphabets such as Telugu interactwith phonological knowledge during theprocessing of meaningful words such thatchildren with more formal instruction inreading are able to access phonologicalinformation better than younger children withless well developed orthographic knowledge.Some pedagogic implications of the results arediscussed.  相似文献

This paper reports the results of a study examining the role of early reading instruction on the nonword reading strategies employed by beginning readers. Three groups of children given different styles of reading instruction were asked to read a list of nonwords presented (a) in isolation and (b) using the clue word technique (Goswami, 1986, 1988). The three groups of children were following either (i) the Early Reading Research project (small units instruction), (ii) the National Literacy Project (instruction emphasising onset‐rime and rhyme awareness), or (iii) usual classroom practice (combined large and small units instruction). Children given small units instruction (Early Reading Research) were found to make significant use of grapheme‐phoneme correspondences (GPCs) and were more accurate than the other two groups of children at reading the nonword items. The National Literacy Project children demonstrated a preference for a rime‐based strategy, once familiarity with the analogous words was controlled, and made significantly more use of this strategy than the Early Reading Research children. The results suggest that early reading instruction does have a significant impact on early reading strategies and should be taken into account in future studies of this type.  相似文献

Two experiments investigated the use of orthographic analogies in 6 year olds. In Experiment 1, 26 children were shown CVC clue and target word pairs sharing either rimes (`fork' – `pork'), heads (`fork' – `ford') or were controls (`fork' – `hurl'). A modest advantage for rime-clued over head-cluedtargets was unreliable over by-subject and by-item analyses. Improvements in target word reading were correlated with pretest scaffolding errors (e.g. `pork' misread as `park'). In Experiment 2, 50 children were pretaught three clue words for each target word before being shown words that shared either rimes (`leak' – `peak'), or medial vowel digraphs (`leak') – `bean'), or were controls (`leak' – `herd'). A modest advantage for rime-clued over vowel digraph-clued targets was again unreliable over by-subject and by-item analyses. Neither rime nor phoneme awareness measures were correlated with rime inference use. Vowel, but not rime inference, was correlated with scaffolding errors. Rime detection was the strongest predictor of reading ability, whereas phoneme segmentation was the strongest predictor of the use of scaffolding errors.  相似文献

There is growing evidence that children develop orthographic knowledge from the very beginning of literacy acquisition. This study investigated the development of German‐speaking children's orthographic knowledge with a nonword choice task. One nonword in each pair contained a frequent consonant doublet (zommul) and the other nonword contained an infrequent doublet (zobbul). Children (N = 54) performed at chance level in kindergarten but chose nonwords with frequent doublets significantly more often than expected by chance in first and second grade. Correlations between children's orthographic knowledge and their reading and spelling skills were not found. The results indicate that knowledge of frequent double consonants is evident in German‐speaking children from first grade onwards, but it is not related to their reading and spelling performance. This finding is consistent with the view that children in transparent orthographies rely less on frequent letter patterns during reading and spelling compared to children in deep orthographies.  相似文献

Three experiments investigated the effects of rime consistency on reading and spelling among developing readers ranging in age from 7 to 11 years. Experiment 1 found that children read words with inconsistent feedforward mappings between orthography and phonology (O → P) less accurately than consistent words. OP consistency interacted with chronological age, word frequency and age-of-acquisition (AoA). The effect of OP consistency on reading was larger for younger children than for older children and OP consistency had an effect for low frequency words and late-acquired words only. Experiment 2 found an effect of feedforward consistency between phonology and orthography (P → O) on children’s spelling but no interaction between PO consistency and AoA. Experiment 3 showed that the effects of feedforward consistency are independent of feedback consistency. Our results challenge models of reading and spelling that assume feedforward consistency effects are influenced by the frequency of exposure to words only and we suggest that interactions between consistency and AoA depends on the ratio of consistent to inconsistent OP mappings.  相似文献

The present study retrospectively examined early difficulties with phonological coding and phonemic segmentation of German children who after four years in school were diagnosed as dyslexic. German, in comparison to English, exhibits rather simple and straight-forward grapheme-phoneme correspondences, and the initial teaching approach was phonics oriented. Despite these favorable circumstances for the acquisition of phonological coding, the majority of the later dyslexic children had particular difficulties with the accurate reading of nonwords and of unfamiliar words after about seven months of reading instruction. However, there were enormous differences between the dyslexic children. Two of them were completely unable to blend phonemes into pronunciations, another seven were slow and error prone decoders, and three children had slow and laborious pronunciation assembly as the core problem. The majority of the later dyslexic children also exhibited phonemic segmentation deficits as tested with a nonword spelling task and a phoneme reversal task. In correspondence with findings from older German dyslexic children, the early difficulties with accurate phonological coding and phonemic segmentation were no longer found at the end of grade four. Children then suffered from very slow reading and poor spelling. In general, the difficulties of German dyslexic children emphasize the phonological impairment account of dyslexia. More specifically, these findings suggest that the assembly of letter sounds into pronunciations is particularly affected in the early phase of learning to read a consistent orthography.  相似文献

Three experiments (= 130) used a minimal group manipulation to show that just perceived membership in a social group boosts young children's motivation for and learning from group‐relevant tasks. In Experiment 1, 4‐year‐old children assigned to a minimal “puzzles group” persisted longer on a challenging puzzle than children identified as the “puzzles child” or children in a control condition. Experiment 2 showed that this boost in motivation occurred only when the group was associated with the task. In Experiment 3, children assigned to a minimal group associated with word learning learned more words than children assigned an analogous individual identity. The studies demonstrate that fostering shared motivations may be a powerful means by which to shape young children's academic outcomes.  相似文献

Children’s skill at recoding graphemes to phonemes is widely understood as the driver of their progress in acquiring reading vocabulary. This recoding skill is usually assessed by children’s reading of pseudowords (e.g., yeep) that represent “new words.” This study re-examined the extent to which pseudoword reading is, itself, influenced by orthographic rimes (e.g., eep) of words of the child’s reading vocabulary, during the development of reading skill. In Study 1, children with word reading levels of 6–10 years read matched pseudowords that do and do not share an orthographic rime with words of their reading vocabularies. Study 2 was conducted to further examine such a comparison for children of the 6- to 8-year word reading levels. There was a small and constant advantage of shared lexical orthographic rimes for children with reading levels 6–8 years but from 8 to 10 years that advantage increased significantly, as expected by Ehri’s phase account of word reading development. The pseudoword reading of children learning to read English involves use of lexical orthographic components as well as context-free recoding of graphemes to phonemes. This implies a qualification to the common interpretation of pseudoword reading as a measure of context-free grapheme–phoneme recoding. Such a measure should use selected pseudowords that do not share orthographic rime units or other multigrapheme components with words of the children’s reading vocabularies.  相似文献

This study explores whether two computer‐based literacy interventions – a ‘synthetic phonics’ and an ‘analytic phonics’ approach produce qualitatively distinct effects on the early phonological abilities and reading skills of disadvantaged urban Kindergarten (Reception) children. Participants (n=53) were assigned by random allocation to one of the two interventions. Each intervention was generally delivered three times per week for 13 weeks as part of a reading centre approach in Kindergarten classrooms with small groups of children. In the synthetic programme children showed, as predicted, significant (p<.05) improvement in CV and VC word blending and the articulation of final consonants. The children in the analytic phonics programme showed, as predicted, significant (p<.05) improvements in articulating shared rimes in words. These results suggest that synthetic and analytic programmes have qualitatively different effects on children's phonological development. These phonological differences are not however immediately reflected in any qualitative differences in the way children undertook word reading or nonword decoding.  相似文献

Kindergarteners (M age = 6;2) were exposed to novel spoken nonwords and their written forms within a storybook reading context. Following each of 12 stories, the children were required to spell and identify 12 novel written nonwords and then verbally produce and comprehend the spoken version of those words. Results indicated the children acquired initial specific phonological and orthographic representations. Spoken and written word learning skills were strongly associated and both were influenced by the words' linguistic regularities. Spoken word learning ability explained 62% of the variance on a spelling measure, whereas written word learning ability predicted 42% of the variance on a reading measure. The results provide evidence that beginning readers employ simultaneously a mutually shared learning mechanism that is sensitive to statistical regularities of words when engaged in the process of learning new spoken words and their written forms.  相似文献

Building on longitudinal findings of linkages between aspects of teachers' language during instruction and children's use of mnemonic strategies, this investigation was designed to examine experimentally the impact of instruction on memory development. First and second graders (= 54, Mage = 7 years) were randomly assigned to a science unit that varied only in teachers' use of memory‐relevant language. Pretest, posttest, and 1‐month follow‐up assessments revealed that although all participating children learned new information as a result of instruction, those exposed to memory rich teaching exhibited greater levels of strategic knowledge and engaged in more sophisticated strategy use in a memory task involving instructional content than did students exposed to low memory instruction. The findings provide support for a causal linkage between teachers' language and children's strategic efforts.  相似文献
