Matching phonemes (speech sounds) to graphemes (letters and letter combinations) is an important aspect of decoding (translating print to speech) and encoding (translating speech to print). Yet, many teacher candidates do not receive explicit training in phoneme-grapheme correspondence. Difficulty with accurate phoneme production and/or lack of understanding of sound-symbol correspondence can make it challenging for teachers to (a) identify student errors on common assessments and (b) serve as a model for students when teaching beginning reading or providing remedial reading instruction. For students with dyslexia, lack of teacher proficiency in this area is particularly problematic. This study examined differences between two learning conditions (massed and distributed practice) on teacher candidates’ development of phoneme-grapheme correspondence knowledge and skills. An experimental, pretest-posttest-delayed test design was employed with teacher candidates (n?=?52) to compare a massed practice condition (one, 60-min session) to a distributed practice condition (four, 15-min sessions distributed over 4 weeks) for learning phonemes associated with letters and letter combinations. Participants in the distributed practice condition significantly outperformed participants in the massed practice condition on their ability to correctly produce phonemes associated with different letters and letter combinations. Implications for teacher preparation are discussed. 相似文献

Visual processing of pictures and letters in alphabet books and the implications for letter learning
《Contemporary educational psychology》2014,39(2):156-163
Alphabet books as studied in this research typically highlight one letter per page combined with a depiction of a word that begins with the letter (e.g., a bear illustrates B). This study tests whether children’s letter knowledge improves as a result of alphabet book sharing and how the visual processing of pictures and letters affects learning from repeated alphabet book readings. The study is designed as a randomized control trial in which participants were assigned to one of two experimental groups (N = 30) or a control group (N = 15). Half of the experimental group received version A in which the letters A–L were illustrated with anthropomorphic figures and the letters M–Z with objects. Half received version B in which the letters A–L were illustrated with objects and the letters M–Z with anthropomorphic figures. Mean age of the children was 57.6 months (SD = 3.6). While sharing the alphabet book we registered children’s eye movements in the first and fourth (last) reading session. Alphabet book reading stimulated letter knowledge although the make-up of the alphabet book moderated the effects. Relatively more visual attention to pictures of anthropomorphic figures interfered with learning letters from alphabet book sharing. Visual attention to letters also predicted letter knowledge and learning. Only a small part of each letter attracted children’s attention and the briefer their fixations on this distinctive area, the more letters they knew at the pretest and were able to learn from alphabet book sharing. 相似文献

Learning about letters is an important component of emergent literacy. We explored the possibility that parent speech provides information about letters, and also that children’s speech reflects their own letter knowledge. By studying conversations transcribed in CHILDES (MacWhinney, 2000) between parents and children aged one to five, we found that alphabetic order influenced use of individual letters and letter sequences. The frequency of letters in children’s books influenced parent utterances throughout the age range studied, but children’s utterances only after age two. Conversations emphasized some literacy-relevant features of letters, such as their shapes and association with words, but not letters’ sounds. Describing these patterns and how they change over the preschool years offers important insight into the home literacy environment. 相似文献

The present study examined the role of derived relations in the generalizability of the evaluative conditioning effect. Healthy university students participated. Four geometrical shapes were first established as discriminative stimuli for the contingent presentation of pictograms (B1, B2, C1, and C2, respectively). We then assessed the reinforcing properties of B1 versus B2, and C1 versus C2 by using simultaneous discrimination tasks: at baseline (baseline assessment), after pairing B1 with aversive slides plus noise and B2 with pleasant slides (test I), and after employing equivalence training and testing to establish B1 as equivalent to C1 and B2 as equivalent to C2 (test II). Most participants (82 %) in the experimental condition, as compared with the control conditions (17 % and 10 %), selected the discriminative shapes for B2 (test I) and C2 (test II) on most trials, replicating and extending previous findings. Subsequently, the geometrical shapes were established as equivalent to the letters X, Y, W, and Z, respectively, which then served as antecedent stimuli in simultaneous discrimination tasks as before (test III). As was expected, only participants in the experimental condition showed preference for the novel letters that were established as equivalent to B2-producing and C2-producing shapes. These findings suggest that the evaluative conditioning effect may extend far beyond the stimulus being de/valuated and narrow the behavioral repertoire. 相似文献

Games provide important informal learning activities for young children, and spatial game play (e.g., puzzles and blocks) has been found to relate to the development of spatial skills. This study investigates 4‐ and 5‐year‐old children's use of scaled and unscaled maps when solving mazes, asking whether an important aspect of spatial learning—the ability to use scaled representations—is related to children's play with scaled maps. Results show that almost all children used the maps to solve the mazes at least occasionally, and use them consistently across maze difficulty and different types of maps. Map use and more accurate spatial scaling were associated with better maze performance. We suggest that maze activities including scaled maps might provide an opportunity for developing children's spatial scaling through play, and discuss future research directions. 相似文献

Joint writing activities between parent and child can enhance literacy skills in young children. This paper describes the strategies used by a mother to scaffold her daughter’s alphabet letter shaping, word and story writing in the years before formal schooling. The strategies included identifying alphabet letters embedded in environmental print and books, tracing letter shapes with fingers whilst using directional language, and using whole‐arm movements to form letter shapes in the air. Writing samples and examples of parent–child interactions were collected at three to four years of age and are described within the framework of Gentry’s writing stages. The joint writing techniques and activities illustrated in this case study emphasise the use of letter names and letter shapes and may provide effective strategies for parents and early childhood educators to scaffold emergent writing development in young children. 相似文献

Letter names are stressed in informal and formal literacy instruction with young children in the US, whereas letters sounds are stressed in England. We examined the impact of these differences on English children of about 5 and 6 years of age (in reception year and Year 1, respectively) and US 6 year olds (in kindergarten). Children in both countries spelled short vowels, as in bag, more accurately than long vowels, as in gate. The superiority for short vowels was larger for children from England, consistent with the instructional emphasis on letter sounds. Errors such as gat for words with long vowels such as gate were more common among US children, reflecting these children’s use of vowels’ names as a guide to spelling. The English children’s performance on a letter knowledge task was influenced by the fact that they are often taught letter sounds with reference to lowercase letters and letter names with reference to uppercase letters, and their spellings showed some effects of this practice. Although emphasis on letter sounds as opposed to letter names influences children’s patterns of performance and types of errors, it does not make the difficult English writing system markedly easier to master. 相似文献

Learning about letters, and how they differ from pictures, is one important aspect of a young child??s print awareness. To test the hypothesis that parent speech provides children with information about these differences, we studied parent?Cchild conversations in CHILDES (MacWhinney, 2000). We found that parents talk to their young children about letters, differentiating them from pictures, by 1?C2?years of age and that some of these conversational patterns change across the preschool years in ways that emphasize important features of letters, such as their shape. We also found that children talk about letters and pictures in distinct ways, suggesting an implicit understanding of some of the differences between letters and pictures at an early age. Some differences in parent?Cchild conversations about letters were found as a function of socioeconomic status: Lower SES families appeared to focus more on alphabetic order than higher SES families. The general letter knowledge expressed in these conversations suggests that everyday interactions are an important component of the home literacy environment and that they differ, in some respects, as a function of child age and family background. 相似文献

Previous research has suggested that handwriting letters may be an important exerciser to facilitate early letter understanding. Experimental studies to date, however, have not investigated whether this effect is general to any visual–motor experience or specific to handwriting letters. In the present work, we addressed this issue by testing letter knowledge using three measures in preschool children before and after a school-based intervention. Participants were divided into four training groups (letter-writing, digit-writing, letter-viewing, digit-viewing) that either wrote letters or digits or viewed letters or digits, twice a week for 6 weeks. We hypothesized that the visual–motor experience of handwriting letters or digits would improve letter knowledge more than viewing experience and that this effect would not be specific to training with letters. Our results demonstrated that the writing groups improved in letter recognition—one component of letter knowledge—significantly more than the viewing groups. The letter-writing group did not improve significantly more than the digit-writing group. These results suggest that visual–motor practice with any symbol could lead to increases in letter recognition. We interpret this novel finding as suggesting that any handwriting will increase letter recognition in part because it facilitates gains in visual–motor coordination. 相似文献

The visual deficit hypothesis of development dyslexia has largely been abandoned because many of the phenomena that initially motivated it could not be replicated under controlled experimental conditions, while phonological processing deficits were found to provide a better explanation for the replicable phenomena. Nevertheless, many teachers and special educators continue to subscribe to the hypothesis that deficits of visual perception are a major cause of reading failure in dyslexia. As part of a larger family study, we reexamined the questions (1) whether probands and affected relatives in dyslexia families reverse easily confused letters more frequently under experimental conditions than normal readers from the same families, and (2) whether they show unusual facility in reading geometrically transformed text. The findings indicated that young dyslexia students reverse easily confused letters more often than normal readers. Reading group differences of letter reversal were significant in children from 7–10 years but not thereafter; and virtually no subject reversed letters when spelling whole words. Furthermore, dyslexic persons in every age group from 7–60 years actually took longer than normal readers to decode geometrically transformed text; and the time to decode transformed texts increased progressively with age after adolescence in both dyslexic persons and normal readers. Thus, reading group differences in decoding easily confused letters and reading geometrically transformed text do not support the visual deficit hypothesis and probably do not help to clarify the etiology of developmental dyslexia. 相似文献

This study tested four complementary hypotheses to characterize intrinsic and extrinsic influences on the order with which preschool children learn the names of individual alphabet letters. The hypotheses included: (a) own-name advantage, which states that children learn those letters earlier which occur in their own names, (b) the letter-order hypothesis, which states that letters occurring earlier in the alphabet string are learned before letters occurring later in the alphabet string, (c) the letter-name pronunciation effect, which states that children learn earlier those alphabet letters for which the name of the letter is in the letter's pronunciation, and (d) the consonant-order hypothesis, which states that children learn earlier those letters for which corresponding consonantal phonemes are learned early in phonological development. Participants were 339 four-year-old children attending public preschool classrooms serving primarily low-income children. Children's knowledge of each of the 26 alphabet letters was assessed, and these data were tested for the four hypotheses using a linear logistic test model (LLTM). Results from the LLTM confirmed all four hypotheses to show that the order of letter learning is not random, in that some letters hold an advantage over other letters to influence their order of learning. Implications for educational policy and practice are discussed. 相似文献

The impact of multisensory instruction on learning letter names and sounds,word reading,and spelling
The purpose of this study was to investigate whether the use of simultaneous multisensory structured language instruction promoted better letter name and sound production, word reading, and word spelling for second grade children with typical development (N = 6) or with dyslexia (N = 5) than structured language instruction alone. The use of non-English graphemes (letters) to represent two pretend languages was used to control for children’s lexical knowledge. A multiple baseline, multiple probe across subjects single-case design, with an embedded alternating treatments design, was used to compare the efficacy of multisensory and structured language interventions. Both interventions provided explicit systematic phonics instruction; however, the multisensory intervention also utilized simultaneous engagement of at least two sensory modalities (visual, auditory, and kinesthetic/tactile). Participant’s graphed data was visually analyzed, and individual Tau-U and weighted Tau-U effect sizes were calculated for the outcome variables of letter name production, letter sound production, word reading, and word spelling. The multisensory intervention did not provide an advantage over the structured intervention for participants with typical development or dyslexia. However, both interventions had an overall treatment effect for participants with typical development and dyslexia, although intervention effects varied by outcome variable. 相似文献

The present study examined whether explicit training of letter-clusters leads to more gains in word-reading speed than training of the separate letters of the same clusters. Ninety-nine poor reading second-grade children were randomly assigned to a cluster-training, a parallel letter-training, or a no-training condition. The cluster-training condition showed superior short-term and long-term improvement on rapid naming of trained and untrained letter clusters, whereas the letter-training condition showed superior short-term improvement on rapid naming of trained letters. In addition, compared with the no-training condition, the cluster and letter training showed the same superior short-term and long-term improvement on trained words and pseudowords. However, both training conditions showed only marginally more short-term improvement for untrained pseudowords and only marginally more long-term improvement on a word reading-fluency task. Apparently, improvement of rapid naming of letter clusters does not, or barely, result in improvement of untrained words and pseudowords. 相似文献

The ways in which parent-child interactions can encourage the development of emergent literacy skills in young children remains
to be fully explored. The present report describes how one parent scaffolded her young child’s emergent writing and letter
knowledge in the home. Environmental print provided many rich and meaningful examples for the parent to show that print conveys
meaning and is constructed with letters that have names and make sounds. The parent used idiomorphs, a multisensory approach
incorporating the tracing of letters and whole body movements, and common household objects to guide the child’s learning
of letter names, sounds, and shapes. Emergent writing skills were scaffolded by using directional language and by the child
copying environmental print. The strategies and examples that are described may give guidance to parents and teachers on how
to provide engaging opportunities for literacy learning in the home environment or in an early educational context. 相似文献

In this paper we review the literature on visual constraints in written word processing. We notice that not all letters are equally visible to the reader. The letter that is most visible is the letter that is fixated. The visibility of the other letters depends on the distance between the letters and the fixation location, whether the letters are outer or inner letters of the word, and whether the letters lie to the left or to the right of the fixation location. Because of these three factors, word recognition depends on the viewing position. In languages read from left to right, the optimal viewing position is situated between the beginning and the middle of the word. This optimal viewing position is the result of an interplay of four variables: the distance between the viewing position and the farthest letter, the fact that the word beginning is usually more informative than the word end, the fact that during reading words have been recognised a lot of times after fixation on this letter position and the fact that stimuli in the right visual field have direct access to the left cerebral hemisphere. For languages read from right to left, the first three variables pull the optimal viewing position towards the right side of the word (which is the word beginning), but the fourth variable counteracts these forces to some extent. Therefore, the asymmetry of the optimum viewing‐position curve is less clear in Hebrew and Arabic than in French and Dutch. 相似文献

Research into sighted children’s reading shows that letter recognition skill predicts phonological awareness skill. Congenitally–blind children do not receive exposure to environmental print and do not generally learn to recognise written letters of the alphabet prior to schooling in Braille. A cross–sectional analysis revealed that blind children with no knowledge of written letters or written words showed no ability at measures of phonological awareness. Blind children with knowledge of written letters and no written words showed much increased phonological awareness scores and blind children with knowledge of written letters and written words scored higher still on phonological awareness measures. It was concluded that letter learning is a major contributor to the development of phonological awareness in blind children. It suggests key similarities in the underlying processes of reading development across two different populations using different modalities to learn to read. 相似文献

Young children's knowledge about printed names 总被引：2，自引：0，他引：2
Four experiments examined young children's knowledge about the visual characteristics of writing, specifically personal names. Children younger than 4 years of age, even those who could read no simple words, showed some knowledge about the horizontal orientation of English names, the Latin letters that make them up, and their left-to-right directionality. Preschoolers also had some familiarity with the shapes of the letters in their own first name, especially the leftmost letter. Knowledge of the conventional capitalization pattern for English names emerged later, after a period during which children preferred names in all uppercase letters. When tested with personal names, the kind of word they know best, young children are surprisingly knowledgeable about the visual characteristics of writing. 相似文献

Learning the sounds of letters is an important part of learning a writing system. Most previous studies of this process have
examined English, focusing on variations in the phonetic iconicity of letter names as a reason why some letter sounds (such
as that of b, where the sound is at the beginning of the letter’s name) are easier to learn than others (such as that of w, where the sound is not in the name). The present study examined Hebrew, where variations in the phonetic iconicity of letter
names are minimal. In a study of 391 Israeli children with a mean age of 5 years, 10 months, we used multilevel models to
examine the factors that are associated with knowledge of letter sounds. One set of factors involved letter names: Children
sometimes attributed to a letter a consonant–vowel sound consisting of the first phonemes of the letter’s name. A second set
of factors involved contrast: Children had difficulty when there was relatively little contrast in shape between one letter
and others. Frequency was also important, encompassing both child-specific effects, such as a benefit for the first letter
of a child’s forename, and effects that held true across children, such as a benefit for the first letters of the alphabet.
These factors reflect general properties of human learning. 相似文献
