This study explored the rates of grade retention among children with undiagnosed learning disabilities. During the 1990–91 school year, data were collected on 344 Michigan students who were referred for special-education evaluation due to learning problems. Of the 201 students determined to possess a learning disability (LD), 71.6% had been retained at least once before they were referred for special-education evaluation. Minority and urban LD students were more apt to be retained before being referred for evaluation. Retained LD students were usually one year older than nonretained LD students at the time of special-education referral. Although retention among LD students did not appear to be related to gender or grade placement, retained LD students generally exhibited lower levels of intelligence and weaker skills in reading comprehension, writing, and math at the time of their referral. © 1996 John Wiley & Sons, Inc. 相似文献

Currently, learning disabilities (LD) are diagnosed on the basis of the discrepancy between students' IQ and reading achievement scores. Students diagnosed with LD often receive remedial instruction in resource rooms. The available evidence suggests that the educational policy based on this discrepancy model has not yielded satisfactory results. This has led researchers to try other paradigms, such as the component model and response to intervention, for dealing with children with reading disabilities. The component model of reading (CMR) described in the present article identifies the reading component that is the source of reading difficulty and targets instruction at that component. Study 1 describes the CMR and reports on its validity. Study 2 describes the successful outcome of a 7-year CMR-based reading instruction program. Compared to the discrepancy model, the CMR has demonstrated several advantages. 相似文献

The purpose of this study was to determine whether distinct subgroups of children with learning disabilities could be identified using a single, recently developed instrument—the Differential Ability Scales (DAS). Ward's method of cluster analysis was used to group 83 school-verified children with learning disabilities from the standardization sample. The following six subgroups were identified: (a) generalized, (b) high functioning, (c) normal, (d) underachievement, (e) borderline, and (f) dyseidetic. Not all subgroups displayed the expected discrepancy between intelligence and achievement associated with the current definitions of I.D. In subsequent discriminant analyses, both achievement and diagnostic subtests were necessary for accuracy in classification. This study provided evidence of the DAS's ability to diagnose the learning disabled differentially and provided distinct profiles for LD subgroups. Administration of the diagnostic subtests along with achievement subtests can provide the clinician with valuable diagnostic information for LD. 相似文献

This study sought to identify clusters or subtypes of children with learning disabilities (LD) and documented brain damage (BD) on the basis of a comprehensive neuropsychological battery. Sixty subjects, 24 with LD and 36 with BD, participated in the study. The standard scores for several measures from the Intermediate Battery of the Halstead-Reitan Neuropsychological Battery and other select measures were submitted to Q-Technique factor analysis for the entire sample. Five clusters were determined. No one cluster was composed exclusively of LD or BD subjects, with the proportions of LD and BD varying considerably from one cluster to the next. There were some qualitative differences between the clusters, while quantitative differences also figured prominently. 相似文献

The authors used a large sample of children (N ≈ 7,400) participating in the Early Childhood Longitudinal Study--Kindergarten Cohort (ECLS-K) to estimate kindergarten children's academic achievement growth trajectories in reading and mathematics. The authors were particularly interested in whether the growth trajectories of children with learning disabilities (LD) or speech language impairments (SLI)--as well as those of other groups of children--were consistent with a cumulative or compensatory developmental cycle. Both LD and SLI children displayed significantly lower levels of kindergarten reading achievement than nondisabled children. However, and over the subsequent 5 years of elementary school, only children with SLI lagged increasingly behind nondisabled peers in their reading skills growth. The authors observed a different pattern for mathematics achievement. Children with LD, but not SLI, lagged increasingly behind nondisabled children in their mathematics skills growth. The authors also observed some consistency in "poor-get-poorer" effects across reading and mathematic achievement for additional population subgroups. Those kindergarten children who were from lower socioeconomic status families, who were African American, and who more frequently displayed learning-related behavior problems initially had lower levels of reading and mathematics achievement and also lagged increasingly behind in their acquisition of these skills over time. Some groups of children, including those with SLI, experience a cumulative rather than a compensatory cycle of achievement growth. 相似文献

LD status and achievement: confounding variables in the study of children's social status, self-esteem, and behavioral functioning 总被引：2，自引：0，他引：2
The purpose of the present study was to examine the role of achievement in explaining the poor social and behavioral functioning associated with LD status, and to evaluate potential gender differences in patterns of interpersonal functioning among youth with learning disabilities (LD) and nondisabled (NLD) youth. Thirty-two students with learning disabilities (21 boys, 11 girls) were matched with same-sex, same-race classmates whose reading achievement was low (LA) or average (AA), and these groups were compared on peer ratings of liking and disliking, perceptions of self-worth and social acceptance, and teacher ratings of conduct problems, anxiety-withdrawal, and attention problems. Students with learning disabilities were less accepted and less well-liked than children in the LA or AA groups and also perceived their self-worth and social acceptance to be lower than LA or AA students. Group by Sex interactions were apparent for several of the peer rating and behavioral variables, indicating that different patterns of social and behavioral functioning distinguished LD boys and LD girls from their NLD peers. The findings highlight the potential role of low achievement in peers' dislike of LD girls and suggest the importance of investigating well-defined subgroups of youth with LD in future research. 相似文献

Young children with learning disabilities typically encounter difficulty with academic tasks requiring intentional effort and effective use of metacognitive skills--qualities that competent readers and writers possess. In response to these difficulties, special educators often modify literacy instruction, isolating the "basic skills" of literacy (such as decoding and penmanship) from meaningful reading and writing activities. Such instruction contributes to impoverished notions of literacy and exacerbates problems of metacognition. The two research programs reported here challenge the conventional literacy instruction provided to many young students with LD. The programs are rooted in developmental and cognitive theory and research, as well as emergent literacy theory. The social nature of learning is emphasized, with a focus on the role of the teacher, the form of discourse, and the role of text in literacy instruction. Results show that children with learning disabilities benefit from strategy instruction occurring within classroom cultures that support collaborative discourse, the flexible application of comprehension strategies, and appropriate, meaningful opportunities for reading and writing. 相似文献

This study assessed rates of learning disabilities (LD) by several psychometric definitions in children with epilepsy and identified risk factors. Participants (N = 173, ages 8-15 years) completed IQ screening, academic achievement testing, and structured interviews. Children with significant head injury, chronic physical conditions, or mental retardation were excluded. Using an IQ-achievement discrepancy definition, 48% exceeded the cutoff for LD in at least one academic area; using low-achievement definitions, 41% to 62% exceeded cutoffs in at least one academic area. Younger children with generalized nonabsence seizures were at increased risk for math LD using the IQ-achievement discrepancy definition; age of seizure onset and attention-deficit/hyperactivity disorder (ADHD) were risk factors for reading and math LD using low-achievement definitions. Writing was the most common domain affected, but neither ADHD nor seizure variables reliably identified children at risk for writing LD. Although children with earlier seizure onset, generalized nonabsence seizures, and comorbid ADHD appear to be at increased risk for some types of LD by some definitions, these findings largely suggest that all children with epilepsy should be considered vulnerable to LD. A diagnosis of epilepsy (even with controlled seizures and less severe seizure types) should provide sufficient cause to screen school-age children for LD and comorbid ADHD. 相似文献

This study analyzed the relation and the specific influence of rapid naming (RN) on different reading (decoding accuracy and
reading fluency) and writing components (spelling accuracy and fluency in composition) of European Portuguese. Moreover, it
also compares the influence of Rapid Automatized Naming (RAN) tests (colors, digits) and of a Rapid Alternating Stimulus (RAS)
test (shapes and colors). In a sample composed by normally achieving children, 70 in the first grade and 69 in the second
grade, the results show that, when phonemic awareness is controlled, RN is a significant concurrent predictor of reading and
writing performance. Its impact occurs mainly on reading fluency and is carried out predominantly by the RAN digit test. Nevertheless,
the RAN color test and the RAS shape and color test also significantly predicted reading and writing performance. The results
also indicate that RN has less impact on writing than on reading, and that, when compared with phonemic awareness, it is associated
with distinct written language components. When combined, the data obtained are consistent with the orthographic characteristics
of European Portuguese. 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

Regrouping Wechsler Intelligence Scale for Children‐Third Edition (WISC‐III) subtests into Bannatyne's spatial, conceptual, and sequential patterns has been thought by many to identify children with learning disabilities (LD). This study investigated the prevalence and diagnostic utility of WISC‐III Bannatyne patterns by comparing 1,302 children with LD to 2,158 children in the WISC‐III normative sample. Further analysis was conducted on a subsample of students with specific reading disabilities. Results indicated that the presence of the Bannatyne WISC‐III pattern would not lead to decisions that are useful in differentiating children with LD from children without LD. For example, receiver operating characteristic (ROC) analysis, measured by the area under the curve (AUC), indicated that the Bannatyne WISC‐III pattern exhibited low diagnostic utility (AUC = 0.54–0.55). Due to its inaccuracy, use of the Bannatyne WISC‐III pattern is not recommended. 相似文献

In this systematic review of literature that spans 1975–2015, integrated reading and writing interventions for students with learning disabilities (LD) or students with academic difficulties were evaluated to understand the extant research, identify encouraging practices, and guide future research. Ten studies met inclusion criteria and each study was evaluated according to the relevant What Works Clearinghouse (WWC) design standards. Eight of the 10 investigations were conducted with students in grades 4–8. While only 4 of the 10 studies met WWC design with or without reservations, results from these studies are encouraging. Study findings suggest several areas for immediate future research relating to methodological and treatment variables and considerations for classroom instruction in order to respond to advanced expectations for the successful integration of reading and writing across subjects. In addition to employing stronger experimental designs and additional replications of encouraging studies, future research should explore the utility of integrated reading and writing interventions with secondary students with who have academic difficulties. 相似文献

We compared two instructional models (co‐teaching inclusion and solo‐taught special education) for students with learning disabilities (LD) with regard to their effect on academic achievement and class attendance. Twelve inclusive classes (experimental group) and 13 special education classes (control group) participated in the study. In grade 1, there were eight inclusive classes and nine special education classes with a total of 353 students (195 without disabilities, 58 with LD in inclusion and 100 with LD in special education classes). The data were collected from academic tests. Although our results revealed no significant difference between the two models in terms of target population, objectives and assigned resources, significant differences were observed in the effects on student outcomes in reading/writing and on attendance, as the inclusion model was shown to be globally more effective compared with the special education setting. 相似文献

Learning disabilities (LD) are common in clinical disorders, but no study has compared the relative prevalence in referred children with different diagnoses. Our sample comprised 949 children (6 to 16 years). LD percentages were highest for bipolar disorder (79%), ADHD combined type (71%), autism (67%), ADHD inattentive type (66%), and spina bifida (60%). Children with oppositional-defiant disorder, adjustment disorder, anxiety, and depression had relatively low LD percentages (18–19%). LD in written expression was twice as common as LD in reading or math. Findings indicate that children with neurogenetic disorders should be assessed for possible LD because of the high potential yield and the need to intervene educationally if learning problems exist. 相似文献

The study presented here investigated the performance of children with learning, psychiatric, and attentional disabilities on the Stroop Color and Word Test. Forty‐three children diagnosed with a full battery of tests as learning disabled (LD [reading]) in grades K through 6 were matched on age, gender, ethnicity, and grade with 43 normal controls. They were also matched with groups of 43 children with psychiatric disorders and 43 children with attentional problems. All subjects were given the Stroop test, which took about 4 minutes per subject. The results indicated clear differences between the groups, with the LD and the psychiatric/attention deficit/hyperactivity disorder (ADHD) groups generating unique profiles different from the normal controls. The children with LD showed slower reading speed and less interference, while the subjects with ADHD and diagnoses showed impairment only on the Color‐Word score. A discriminant analysis using the three basic Stroop scales was able to significantly differentiate the LD group from the non–learning‐disabled (NLD) group (89%) and the LD group from a joint Psychiatric/ADHD group (86%). However, results were poorer for differentiating a joint LD/ADHD group from the NLD group (68%) and the LD from the ADHD group (59%). © 2002 Wiley Periodicals, Inc. 相似文献

Social information processing, security of attachment, and emotion regulation in children with learning disabilities 总被引：1，自引：0，他引：1
This study examined the contribution of attachment security and emotion regulation (ER) to the explanation of social information processing (SIP) in middle childhood boys with learning disabilities (LD) and without LD matched on age and grade level. Children analyzed four social vignettes using Dodge's SIP model and completed the Kerns security scale and the children's self-control scale. Study results demonstrated major difficulties in SIP, lower attachment security, and less ER in children with LD compared to children without LD. Attachment as well as the interaction between attachment and ER emerged as important contributors to most SIP steps, suggesting that children with higher security who also have better ER skills will have better SIP capabilities along the different steps, beyond group inclusion. Results were discussed in terms of practical and clinical implications regarding the importance of mother-child attachment and ER skills for social cognitive capabilities in children with LD. 相似文献

This study examined patterns of close relationships among school‐age children with learning disabilities (LD) as manifested in their attachment style, their self‐perceived loneliness, their sense of coherence, and teacher ratings of their academic functioning. In line with resilience theory, this study also aimed to further explore predictors of positive adjustment for children with LD. The sample comprised 98 children with LD from regular classes in four Israeli public elementary schools, and 98 non‐LD children from the same classes. Significant group differences emerged in attachment styles and adjustment. Attachment style significantly correlated with socioemotional adjustment but not with academic functioning. In addition, a subgroup of resilient children emerged among the LD children. Discussion focused on the value of attachment patterns for understanding social and emotional adjustment among school‐age children with LD. 相似文献

The main purposes of this research were twofold. We examined the samenesses about learning disabilities (LD) in Guatemala and Spain, two countries with the same language but cultural, political, and educational differences, first analyzing data about the prevalence of reading and spelling disabilities in Guatemala City and the Spanish region of the Canary Islands. The focus of the second study was to determine whether there are cross‐national patterns of significant differences in cognitive processes associated with reading and spelling disabilities from a developmental approach in these two cultural contexts. We found some differences in the prevalence of specific LD in reading between both countries but we did not find significant differences between Guatemalan and Spanish reading‐disabled children in cognitive processes that are involved in reading and spelling acquisition in spite of the cultural and educational differences between the two countries. 相似文献

The purpose of this study was to improve the reading performance of children with learning disabilities using a classroom-based metacognitive reading program. The participants were third- and fourth-level 8- and 9-year-olds (13 boys and 5 girls) at a school for children with learning disabilities. A cross-sectional time series design was used. During pre- and posttesting participants were assessed on two measures of strategy awareness and a measure of perceived self-competence. During the instructional phase the metacognitive reading program was introduced. Participants were assessed on measures of reading performance throughout the study. In general, the findings were positive: Students increased in performance and awareness of strategies from pre- to posttesting. In addition, participants were placed in subgroups based on pretesting assessments. The subgroups differed on their improvements over time. This study provides preliminary evidence that a metacognitive reading program can be used with children with learning disabilities to improve their awareness about reading and their comprehension skills. 相似文献
