The utility of computerized analysis of variables cited as predictors of success in written expression was examined. The analysis of compositions written by 423 university students revealed a three-factor structure on 17 variables associated with written expression. A comparison of compositions written by university students with and without learning disabilities was conducted on the three factors identified as vocabulary/fluency, syntactic maturity, and vocabulary/diversity. Students with learning disabilities differed significantly on the factors labeled vocabulary/fluency and syntactic maturity. Students with learning disabilities were not as fluent in word production and in the number of different words used in their compositions as their non-learning-disabled peers. They did, however, produce longer sentences and T-units. The findings of this study suggest that emphasis on the postsecondary level needs to focus on expanding the use of written vocabulary skills, and that the T-unit may not be the best determiner of syntactic complexity at the adult level. 相似文献

This study examined the story composition abilities of learning disabled (LD) and normally achieving young adolescents as indicated by measures of writing category, cohesion, and fluency. Findings suggest that although adolescents with learning disabilities have a rudimentary knowledge of story form, this knowledge is less well developed than that of their nondisabled peers. Students with learning disabilities also had greater coherence problems in their writing and were less fluent writers. Several important age trends were noted when results of this investigation were compared with outcomes from a similar investigation involving younger students. 相似文献

The purpose of this study was to investigate the occurrence and severity of reading, spelling, and written language impairment
in children clinically referred for Attention Deficit Hyperactivity Disorder (ADHD). Specific questions involved 1) whether
ADD subgroups with and without hyperactivity differ in reading, spelling, and written language achievement, 2) whether age
and gender interact with ADD sub-group class to affect reading/written language achievement, and 3) whether prevalence of
impaired reading/written language in these subgroups is consistent with previous reports in heterogeneous samples. Subjects
were 115 ADD children aged 6-12 who were subclassified as ADD + H(72 percent) and ADD - H(28 percent) by objective teacher
ratings. Dependent measures included tests of single word recognition and vocabulary, word attack, contextual comprehension,
written spelling, written sentence construction, and writing fluency, in addition to a structured behavioral observation,
during which aspects of inattention and motor activity were coded. A large fraction of this sample met public school LD criteria
(54 percent), and achievement on most measures was globally poorer than the respective test normative groups. The ADD + H
subgroup showed significantly poorer word attack skills, while the subgroups did not significantly differ from each other
on other reading/written language measures. However, 17 percent of the total ADD sample were ≥ 1.5 SD below the mean in total
reading achievement, and 29 percent were ≥ 1.5 SD below the mean on measures of written spelling/language. Gender X age interactions,
indicating poorer performance in the middle age group of females, were likely related to lower IQ. 相似文献

In this study, we performed a fine grained analysis of writing by children with a specific language impairment (SLI) and examined the contribution of oral language, phonological short-term memory (STM), nonverbal ability, and word reading to three writing constructs (productivity, complexity and accuracy). Forty-six children with SLI were compared with 42 children matched for chronological age, receptive vocabulary (N = 46) and reading decoding (N = 46) on a measure of narrative writing. The SLI group performed worse on all measures compared to children of a similar chronological age. The SLI group produced a greater proportion of orthographic spelling errors than children with similar receptive vocabularies, but were comparable to children matched for reading decoding. The children with SLI showed specific difficulties in the omission of whole words (e.g. auxiliary verbs and subject nouns) and omissions of grammatical morphology (e.g. past tense—ed) reflecting the difficulties shown in their oral language. Receptive grammar made a significant contribution to writing complexity and accuracy. Phonological fluency contributed to writing productivity, such as the production of diverse vocabulary, ideas and content and writing fluency. Phonological STM and word reading explained additional variance in writing accuracy over and above the SLI group’s oral language skills. 相似文献

Written expression of students with and without learning disabilities: differences across the grades 总被引：2，自引：0，他引：2
This study compares the written expression of 48 students with learning disabilities (LD) and 48 normally achieving (NA) students (Grades 4, 8, and 11). Productivity, syntactic maturity, vocabulary, and mechanics were examined using writing samples obtained in response to a standard stimulus. Results indicate that, compared to their NA peers, students with learning disabilities write fewer words and sentences, write more words per sentence, produce fewer words with seven letters or more and fewer sentence fragments, and have a higher percentage of capitalization and spelling errors. No group differences were found for the number of T-units produced or the number of morphemes per T-unit. Comparison of group differences at each grade level and differences by groups across the grades reveals persistent written expression difficulties and signals a need for a careful review of current instructional practices and how they can be improved. 相似文献

This study used a two-part task format to (a) describe the vocabulary knowledge of 10- and 12-year-old students with learning disabilities and (b) assess the effect of task alternatives on their vocabulary knowledge. We addressed these research objectives by comparing the performance of 24 students with learning disabilities to an equal number of their normally achieving peers. Vocabulary knowledge was first assessed through a production task. In the even the student's response was inaccurate or incomplete, an identification task assessing the same vocabulary term was presented. Results revealed that, compared to normally achieving students, students with learning disabilities are (a) significantly less able to construct fully specified responses to production tasks, (b) comparable in their ability to use pictorial responses to demonstrate vocabulary knowledge not accessible in production tasks, and, (c) when equated in reading achievement, only 10-year-olds are significantly poorer in composite vocabulary knowledge. 相似文献

Alternative models of the structure of individual and developmental differences of written composition and handwriting fluency
were tested using confirmatory factor analysis of writing samples provided by first- and fourth-grade students. For both groups,
a five-factor model provided the best fit to the data. Four of the factors represented aspects of written composition: macro-organization
(use of top sentence and number and ordering of ideas), productivity (number and diversity of words used), complexity (mean
length of T-unit and syntactic density), and spelling and punctuation. The fifth factor represented handwriting fluency. Handwriting
fluency was correlated with written composition factors at both grades. The magnitude of developmental differences between
first grade and fourth grade expressed as effect sizes varied for variables representing the five constructs: large effect
sizes were found for productivity and handwriting fluency variables; moderate effect sizes were found for complexity and macro-organization
variables; and minimal effect sizes were found for spelling and punctuation variables. 相似文献

Identical and fraternal twins (N?=?540, age 8 to 18 years) were tested on three different measures of writing (Woodcock-Johnson III Tests of Achievement—Writing Samples and Writing Fluency; Handwriting Copy from the Group Diagnostic Reading and Aptitude Achievement Tests), three different language skills (phonological awareness, rapid naming, and vocabulary), and three different reading skills (word recognition, spelling, and reading comprehension). Substantial genetic influence was found on two of the writing measures, writing samples and handwriting copy, and all of the language and reading measures. Shared environment influences were generally not significant, except for Vocabulary. Non-shared environment estimates, including measurement error, were significant for all variables. Genetic influences among the writing measures were significantly correlated (highest between the speeded measures writing fluency and handwriting copy), but there were also significant independent genetic influences between copy and samples and between fluency and samples. Genetic influences on writing were significantly correlated with genetic influences on all of the language and reading skills, but significant independent genetic influences were also found for copy and samples, whose genetic correlations were significantly less than 1.0 with the reading and language skills. The genetic correlations varied significantly in strength depending on the overlap between the writing, language, and reading task demands. We discuss implications of our results for education, limitations of the study, and new directions for research on writing and its relations to language and reading. 相似文献

This study documents the amount and quality of reading instruction provided to second‐ through fifth‐grade students with learning disabilities provided resource‐room services. Reading instruction provided by 10 special education resource‐room teachers was observed. Findings reveal that teachers and students were on task during instructional time that included phonological awareness, word study, comprehension, reading fluency, and vocabulary instruction of average to high average quality. Although class size was small overall, whole‐group instructional delivery was most common. Students made statistically significant gains in oral reading fluency but did not increase their standard scores on measures of comprehension or word reading. © 2010 Wiley Periodicals, Inc. 相似文献

This study examined the executive functioning of 55 elementary school children with and without problems in written expression. Two groups reflecting children with and without significant writing problems were defined by an average primary trait rating across two separate narratives. The groups did not differ in terms of chronological age, ethnicity, gender, socioeconomic status, special education status, or presence of attention problems or receptive vocabulary capabilities; however, they did differ in reading decoding ability, and this variable was controlled for in all analyses. Dependent measures included tasks tapping an array of executive functions grouped conceptually in accordance with a model of executive functioning reflecting the following domains: initiate, sustain, set shifting, and inhibition/stopping. Analysis of covariance (ANCOVA) procedures revealed statistically significant group differences on the initiation and set shift domains, with the sustaining domain approaching significance. Children with writing problems performed more poorly in each of these domains, although the effect sizes were small. A multiple regression that employed these four factors and the reading decoding variable to predict the primary trait score from the written narratives revealed a statistically significant regression function; however, reading decoding contributed most of the unique variance to the writing outcome. These findings point out the importance of executive functions in the written language process for elementary school students, but highlight the need to examine other variables when studying elementary school-age children with written expression problems. 相似文献

This study investigated both quantitative and qualitative differences between subjects with and without learning disabilities (LD) across three grade levels on two tasks requiring active processing of story grammar. There was no evidence, for either task, of developmental differences in relation to either story comprehension or production. However, there were significant differences between students with LD and normally achieving students in the amount as well as the type of information included in the retellings and written stories. The results provide support for the hypothesis that students with LD have acquired a rudimentary but not fully developed schema for narrative prose. 相似文献

The study investigated the role of word-level and verbal skills in writing quality of learners who spoke English as a first (L1) and second (L2) language. One hundred and sixty-eight L1 and L2 learners (M = 115.38 months, SD = 3.57 months) participated in the study. All testing was conducted in English. There was a statistically significant L1 advantage on the measures of writing quality and verbal skills (i.e., vocabulary, verbal working memory, and semantic fluency) but not on word-level skills (i.e., spelling and word reading). Results from the multi-sample structural equation modeling analysis showed that the word-level and verbal skills made independent contributions to writing quality of L1 and L2 learners and the strength of these relationships was invariant (equivalent) across the two samples. The educational implications of research on L2 learners who are learning to write in a majority language were discussed. 相似文献

There has been considerable discussion of the methods used for the identification of children with reading disabilities. This study examined three different methods that could be used in the identification of children with reading disabilities and their consistency with teacher ratings of behaviors believed to be associated with reading disabilities. Standardized, norm-referenced measures of achievement, phonological processing measures, and curriculum-based measures of reading fluency were used with 40 children in Grades 1 and 2. Comparisons were made to determine which measures, if any, differentiated between children referred for reading disabilities (n = 20) and children who were progressing typically in reading in their general education classroom settings (n = 20). The results indicated significant between-group differences on standardized, norm-referenced measures of reading recognition, word attack, and comprehension; phonological measures of blending nonwords and elision; and reading fluency. Teacher ratings on the Dyslexia Screening Instrument were consistent with teacher beliefs regarding children's progress in reading. All measures were found to correlate significantly with each other. However, correlations were generally in the moderate range, suggesting that the measures used did not measure the same reading skills or, in the case of phonological processing, the underlying abilities believed to be necessary for reading. Given the differences in tasks and the moderate correlations, it is likely that the choice of measures may affect the conclusions reached regarding a student's reading ability. 相似文献

A report of cognitive, academic, and linguistic profiles for college students with and without learning disabilities 总被引：1，自引：0，他引：1
A comparison of cognitive, academic, and linguistic profiles for 74 college students with learning disabilities and 37 college students without learning disabilities resulted in significant differences in achievement for reading, writing, listening, and speaking. No significant differences were found for gender or the presence of a Verbal-Performance split in cognitive ability. Instruments for measuring academic and linguistic skills were similar in their ability to classify students with and without learning disabilities. These findings support the importance of using measures of multidimensional attributes, including language, for making decisions concerning the criteria for learning disabilities. 相似文献

Direct and indirect measures were used to compare the written language abilities of three groups of college students: two with learning disabilities and one without learning disabilities. Main effects were found for group, but not gender. Differences between nonlearning disabled students (NLD) and those with learning disabilities (LD) in writing were evident on both types of measures. Performance by LD students with disabilities in an area other than writing differed depending on the type of measure and often was no different from either of the other two groups. The combined use of direct and indirect measures appeared most effective for examining the complexities of writing produced by all groups. 相似文献

This study examined the effects of extra time on the reading comprehension performance of a heterogeneous group of adults
with reading disabilities. Sixty-four adults participated. A clinic that assesses learning disabilities identified 22 as reading
disabled, and 42 as normal readers. The 64 adults took a reading comprehension test under both timed and untimed conditions.
Other skills measured included vocabulary, word reading, non-word reading, spelling, arithmetic, and short-term memory. Under
timed conditions, there were significant differences between the participants with reading disabilities and the normally achieving
participants. All of the reading disabled participants in the present study benefited from extra time, but the normally achieving
readers performed similarly under the timed and untimed conditions. Further, in the untimed condition, the performance of
the individuals with a less severe reading disability was not significantly different that of the Average readers. The study
suggests that extra time during testing is an appropriate accommodation to help individuals begin to compensate for reading
disabilities. 相似文献

This experimental study reports findings on the effects from a year-long reading intervention providing daily, 50-minute sessions to middle-school students with identified learning disabilities (n = 65) compared with similar students who did not receive the reading intervention (n = 55). All students continued to receive their special education services as provided by the school. Results indicated statistically significant findings favoring the treatment group for sight word reading fluency following intervention. Small effects were found for phonemic decoding fluency and passage comprehension. No other statistically significant differences were noted between groups. The findings suggest that while gains on word reading fluency resulted from the additional reading treatment, accelerating the reading performance of students identified with learning disabilities may be unlikely to result from a one-year, daily intervention provided to students in groups of 10-15. 相似文献
