This replication study examined whether 158 college students classified as learning disabled (LD) who were granted course substitutions for the foreign language (FL) requirement would display significant cognitive and academic achievement differences when grouped by levels of IQ-achievement and achievement-achievement discrepancy and by level of performance on an FL aptitude test (Modern Language Aptitude Test; MLAT), phonological/orthographic processing measures, and in FL courses. The results showed that there were few differences among groups with differing levels of IQ-achievement or achievement-achievement discrepancy (i.e., < 1.0 SD, 1.0-1.49 SD, and > 1.50 SD) on MLAT and American College Testing (ACT) scores, graduating grade point average (GPA), or college FL GPA. The results also showed that between groups who scored at or above versus below the 15th percentile (i.e., < 1.0 SD) on the MLAT, there were no differences on measures of graduating GPA, college FL GPA, native language skill, ACT score, and Verbal IQ. Demographic findings showed that 44% of these petition students met a minimum IQ-achievement discrepancy criterion (> or = 1.0 SD) for classification as LD. These findings suggest that many traditional assumptions about LD and FL learning are likely to be false.  相似文献

Response-to-intervention (RTI) approaches to disability identification are meant to put an end to the so-called wait-to-fail requirement associated with IQ discrepancy. However, in an unfortunate irony, there is a group of children who wait to fail in RTI frameworks. That is, they must fail both general classroom instruction (Tier 1) and small-group intervention (Tier 2) before becoming eligible for the most intensive intervention (Tier 3). The purpose of this article was to determine how to predict accurately which at-risk children will be unresponsive to Tiers 1 and 2, thereby allowing unresponsive children to move directly from Tier 1 to Tier 3. As part of an efficacy study of a multitier RTI approach to prevention and identification of reading disabilities (RD), 129 first-grade children who were unresponsive to classroom reading instruction were randomly assigned to 14 weeks of small-group, Tier 2 intervention. Nonresponders to this instruction (n = 33) were identified using local norms on first-grade word identification fluency growth linked to a distal outcome of RD at the end of second grade. Logistic regression models were used to predict membership in responder and nonresponder groups. Predictors were entered as blocks of data from least to most difficult to obtain: universal screening data, Tier 1 response data, norm referenced tests, and Tier 2 response data. Tier 2 response data were not necessary to classify students as responders and nonresponders to Tier 2 instruction, suggesting that some children can be accurately identified as eligible for Tier 3 intervention using only Tier 1 data, thereby avoiding prolonged periods of failure to instruction.  相似文献

This study surveyed a national sample of school psychologists with respect to the identification of reading disabilities (RD). It covers school psychologists' opinions regarding perceived benefits of the use of cognitive assessment in RD identification, both within and outside of an IQ–achievement discrepancy model. The survey also solicited opinions about the nature of RD, particularly conceptions of general slow learners (and readers) versus those evidencing a discrepancy. Results related to school psychologists' concerns about job security, should IQ testing be reduced, are presented. Furthermore, the perceived benefits of a Response to Intervention (RTI) model, how school psychologists see themselves contributing to an RTI effort, as well as possible hurdles to RTI implementation are covered. Measurement of these perceptions may be beneficial in informing current and future service delivery models for RD identification as well as possible training needs of currently practicing school psychologists. Finally, the current work represents an effort to measure assessment acceptability for RD identification techniques. © 2010 Wiley Periodicals, Inc.  相似文献

The final session of the National Research Center on Learning Disabilities (NRCLD) Responsiveness-to-Intervention (RTI) Symposium, "What are alternative models to LD identification other than RTI?" included four papers that discussed concerns over the exclusive reliance on an RTI approach to learning disability identification, considerations for analyzing proposed LD identification models, and various alternatives to LD identification. The work of the participating panelists is summarized in this discussant paper, and next steps for the NRCLD in light of these presentations are suggested.  相似文献

In this article we discuss research bearing on the traditional use of the IQ-achievement discrepancy to define specific reading disability. We initially review the evidence presented by Rutter and Yule (1975) in support of this practice, and then discuss results from subsequent studies that have questioned the reliability of their findings. We also discuss results from more recent studies demonstrating that the IQ-achievement discrepancy does not reliably distinguish poor from normal readers, whereas language-based measures do reliably distinguish these groups. We highlight results from a study we recently completed, in which it was found that IQ scores did not differentiate between poor readers who were found to be readily remediated and poor readers who were difficult to remediate. In view of the convergent evidence against the use of IQ scores to define specific reading disability, we suggest that the IQ-achievement discrepancy definition of this disorder be discarded.  相似文献

Patterns of performance on the Wechsler Intelligence Scale for Children-Revised (WISC-R) have been proposed as useful tools for the identification of children with learning disabilities (LD). However, most of the studies of WISC-R patterns in children with LD have been plagued by the lack of a typically achieving comparison group, by failure to measure individual patterns, and by the lack of a precise definition of LD. In an attempt to address these flaws and to assess the presence of patterns of performance on the WISC-R, we examined data from 121 children with typical achievement (TA), 143 children with reading disabilities (RD), and 100 children with a specific arithmetic disability (AD), ages 6 to 16 years. The results indicated that the RD and AD groups had significantly lower scores than the TA group on all the Verbal IQ subtests. Many of the children with AD and RD showed a significant difference between Verbal and Performance IQ scores, but so did many of the typically achieving children. Although there were some children with LD who showed the predicted patterns, typically, 65% or more of the children with LD did not. Furthermore, a proportion of the TA group-generally not significantly smaller than that of the RD and AD groups-showed discrepancy patterns as well. Our results indicate that the patterns of performance on intelligence tests are not reliable enough for the diagnosis of LD in individual children. Therefore, it might be more profitable to base the detection of an individual's LD on patterns of achievement test scores.  相似文献

Responsiveness to intervention (RTI) is being proposed as an alternative model for making decisions about the presence or absence of specific learning disability. I argue that there are many questions about RTI that remain unanswered, and radical changes in proposed regulations are not warranted at this time. Many fundamental issues related to RTI are unresolved, and a better strategy may be to more rigorously implement existing identification criteria (e.g., discrepancy and psychological processing deficits) in a structured psychometric framework. Suggestions on how to modify present procedures are provided.  相似文献

Longstanding concern about how learning disabilities (LD) are defined and identified, coupled with recent efforts in Washington, DC to eliminate IQ‐achievement discrepancy as an LD marker, have led to serious public discussion about alternative identification methods. The most popular of the alternatives is responsiveness‐to‐intervention (RTI), of which there are two basic versions: the “problem‐solving” model and the “standard‐protocol” approach. The authors describe both types, review empirical evidence bearing on their effectiveness and feasibility, and conclude that more needs to be understood before RTI may be viewed as a valid means of identifying students with LD.  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

School psychologists' perceptions of how reading disabilities (RD) should be operationalized were examined and compared to those of journal editorial board members in the learning disabilities field ( Speece & Shekitka, 2002 ). Participants were practicing school psychologists drawn from the membership directory of the National Association of School Psychologists (NASP). The sample consisted of 549 participants and was generally representative of the demographic characteristics of NASP membership at large. Results indicated that over 75% of participants endorsed using treatment validity/response to intervention (RTI), cognitive processing, and phonemic awareness as components of RD operationalization. A large percentage (61.9%) also endorsed use of an IQ‐achievement discrepancy criterion. Statistically significant differences were found between the endorsements of this study's participants and those in the Speece and Shekitka (2002) study, with our participants reporting higher endorsement of RTI, cognitive processing, and IQ‐achievement discrepancy criteria.  相似文献
