EVOLUTION,NOT REVOLUTION: SCHOOL PSYCHOLOGISTS’ CHANGING PRACTICES IN DETERMINING SPECIFIC LEARNING DISABILITIES

The profession of school psychology has been impacted by the response to intervention (RTI) model in various ways. RTI data are being used to make decisions regarding academic and behavioral interventions and to make eligibility determinations in comprehensive evaluations conducted by multidisciplinary teams. A survey of almost 400 school psychologist practitioners reveals a changing landscape in terms of school psychologists’ methods of determining eligibility for specific learning disabilities (SLD) in RTI site and non‐RTI site schools. The survey also brings to light differences between numbers of initial evaluations and levels of challenge and job satisfaction. Implications of these changes and future directions for research are discussed.     

What is the Role of Intelligence in the Identification of Specific Learning Disabilities? Issues and Clarifications

A fundamental assumption in the identification of specific learning disabilities (SLD) has been that the presence of a severe discrepancy between ability and academic achievement is a valid marker for the presence of a SLD. This assumption is based on the notion that discrepant low achievers constitute a unique group of children who are different in a number of ways from nondiscrepant low achievers. Several meta‐analytic reviews contrasting discrepant and nondiscrepant low achievers fail to reveal significant differences between these two groups on measures of phonetic analysis, pseudoword decoding, word identification, spelling, oral reading fluency and other measures of literacy development and related phonological processing skills. This paper discusses the role of intelligence in identifying children with SLD and presents data based on correlational analyses and hierarchical regression analyses showing that intelligence is not a strong predictor of reading achievement and does not predict responsiveness to remedial instruction. These data also indicate that direct measures of responsiveness to intervention (RTI) strongly predict later reading achievement in tutored children from 1st grade through 4th grade. The combined results suggest that RTI approaches to the identification of SLD may have greater utility than psychometric approaches based on IQ scores or individual profile analysis.     

Integrating Response to Intervention (RTI) with neuropsychology: A scientific approach to reading

This article integrates the fundamental components of both Response to Intervention (RTI) and cognitive neuropsychology when identifying reading disorders in children. Both proponents of RTI and cognitive neuropsychology agree the discrepancy model is not a reliable or valid method to identify learning disorders in school. In addition, both proponents of RTI and cognitive neuropsychology agree that earlier intervention and the use of evidence‐based intervention techniques must permeate the thinking behind any educational reform. Lastly, both proponents of RTI and cognitive neuropsychology concur with the National Reading Panel's (2000) five core components of the reading process. Given the similarities between RTI and neuropsychological models of reading, a more integrative assessment model will be introduced to better diagnose and remediate subtypes of reading disorders in children. In summary, it is the author's belief that cognitive neuropsychology will emerge as the leading discipline in forging the inevitable alliance between science and education. © 2008 Wiley Periodicals, Inc.     

Neuropsychological aspects for evaluating learning disabilities

This review surveys the empirical literature for assessments of learning problems in children from a neuropsychological perspective. An evaluation of children with learning problems must consider measures of working memory, attention, executive function, and comprehension (listening and written), particularly for children who do not respond to intervention. These constructs must be tied to intervention techniques, and their connections must be empirically verified. The response-to-intervention (RTI) perspective provides excellent support for the process in young children but is still developing the process for students above the second grade. This review provides information about the existing research on neurobiological correlates of learning disabilities, possible areas for further evaluation, and the link to the RTI movement.     

What We Need to Know About Responsiveness To Intervention (and Shouldn't Be Afraid to Ask)

During the past several years, one of the most frequently addressed topics at conferences and in professional journals is responsiveness to intervention (RTI). This is because it is viewed by many as a new way to think about both early intervention and disability identification. Despite its relative newness, a subset of RTI proponents contend researchers and practitioners know everything they need to know to implement it effectively. We disagree and argue that the smartest and most responsible way to move forward with RTI implementation is to recognize what all of us collectively do know and do not know. In this article, we identify unresolved issues—general and specific—important to RTI implementation, teacher effectiveness, and student achievement.     

Response-to-intervention (RTI) as a model to facilitate inclusion for students with learning and behaviour problems

Many students with learning and behaviour problems are routinely excluded from regular education. Although calls have been made to educate students with these problems in the same settings as their typically developing peers, it remains unclear how best to support their needs for academic and behavioural support. We address this question first by describing response-to-intervention (RTI), a specific model of prevention and early intervention for learning and behaviour problems. A comprehensive summary of the RTI literature is provided. Second, we will discuss the feasibility and applicability of RTI as one approach to facilitate inclusion of students with learning and behaviour problems. Specifically, we will demonstrate how RTI can be used to address at least four barriers to inclusion by (1) providing a clear implementation strategy for inclusion practices; (2) clearly defining the roles, responsibilities and collaboration of general and special education teachers; (3) enabling the allocation of resources for instruction and intervention; and (4) avoiding early and unnecessary labelling of students with learning and behaviour problems. Third, limitations of RTI as a model to facilitate inclusion will be discussed.     

Is Response to Intervention Good Policy for Specific Learning Disability?

Abstract The reauthorized Individuals with Disabilities Education Improvement Act ( IDEA ) established new provisions for specific learning disability (SLD) identification, including: (a) no longer requiring consideration of IQ–achievement discrepancy and (b) permitting response to intervention (RTI) as part of SLD evaluation procedures. We discuss several policy implications of these new regulations by considering the original construct of SLD, the still “experimental” status and implementation of RTI, the closer alignment of RTI objectives with No Child Left Behind than former IDEA regulations, and the shift in focus from serving as a special education identification procedure to a general education instructional procedure. We conclude by proposing several recommendations for the appropriate inclusion of both RTI and psychometric evaluation within the continuum of SLD identification procedures.     

Ability and Achievement Characteristics of Australian University Students with Self-Reported Specific Learning Disabilities

There is a lack of empirical data on the ability and achievement characteristics of Australian university students seeking accommodation under the Disability Discrimination Act because of Specific Learning Disabilities (SLD). A series of 30 self-referred students was assessed individually using an extensive test battery (WJ-R) based on a modern, comprehensive model of intelligence and achievement. Comparisons with known characteristics of North American students with and without SLD are reported as well as individual profile patterns relevant to definitions of SLD. Intra-cognitive weaknesses were found in cognitive processing speed, memory, auditory and visual intelligence. Contrary to expectation, reading was not an area of weakness. As expected, basic writing skills were poor for many students (18 out of 30). The variability of profile patterns requires an individualised approach to assessment, careful translation into recommendations, and ongoing evaluation of learning outcomes.     

Do Special Educational Needs courses have any impact on student teachers' perceptions of children with severe learning difficulties?

Teachers' perceptions of their pupils are likely to have significant effects on children's performance and self-concepts. Previous research on expectations of, and attitudes towards, pupils with severe learning difficulties (SLD) has generally shown that teachers perceive such children less positively than nondisabled children. One of the methods that practitioners and researchers have used to influence teachers' perceptions of children with SLD is an education or information-based approach. In the present study, 100 female student teachers completed questionnaires that measured their attributions, expectations, behavioural intentions and emotional responses to children with SLD. The results showed that there were very few differences in the perceptions of students who had completed the Special Educational Needs (SEN) module of their training course compared with students who had not yet completed the module. However, those students with higher levels of previous contact with children with SLD were generally more positive than those with little or no previous experience. The implications of the present findings for teacher training in SEN are discussed. In addition, methodological implications for research on the evaluation of mainstreaming and other research involving the measurement of teachers' perceptions of children are highlighted.     

Extending Responsiveness to Intervention to Mathematics at First and Third Grades

Responsiveness to intervention (RTI) is an innovative approach to the identification of learning disabilities (LD). The central assumption is that RTI can differentiate between two explanations for low achievement: poor instruction versus disability. If the child responds poorly to validated instruction, then the assessment eliminates instructional quality as a viable explanation for poor academic growth and instead provides evidence of a disability. For children who do respond nicely, RTI serves a critical prevention function. Most of RTI research has been focused on early reading. In this article, we describe two ongoing programs of research on RTI in the area of mathematics: one on a comprehensive mathematics curriculum at first grade and the other focused on word problems at third grade. For each research program, we describe the sample, explain how students are identified as at risk for mathematics disability, provide an overview of the interventions to which responsiveness is gauged, and describe some results to date.     

Qualitative differences in learning disabilities across postsecondary institutions

Many college students receiving accommodations for specific learning disability (SLD) do not meet objective criteria for the disorder. Furthermore, whether students meet criteria depends on the diagnostic decision model used by their clinician. The authors examined whether the relationship between diagnostic model and likelihood of meeting objective criteria is moderated by students' postsecondary institution. They administered a comprehensive psychoeducational battery to 98 undergraduates receiving accommodations for SLD at 2-year public colleges, 4-year public universities, and 4-year private colleges. Most 4-year public university students failed to meet objective criteria for SLD. In contrast, most 4-year private college students met objective criteria based on significant ability-achievement discrepancies, and most 2-year public college students met objective criteria based on normative deficits in achievement and cognitive processing. Students who met objective criteria also differed significantly in degree of academic impairment. The authors' findings indicate qualitative differences in SLD across postsecondary settings and have implications for the identification and mitigation of SLD in college students.     

Response to intervention for reading difficulties in the primary grades: some answers and lingering questions

The purpose of this article is to describe the current research base and identify research needs related to response to intervention (RTI) frameworks in primary-grade reading. Research is reviewed on early reading instruction and intervention, the implementation of multitiered reading interventions, and the determination of intervention responsiveness. Areas identified as in need of research include (a) the conditions under which early reading interventions are most effective in RTI contexts, (b) multitiered interventions for students with limited English proficiency, (c) reading instruction for students who make limited progress in Tier 3 intensive interventions, (d) criteria for determining intervention responsiveness, and (e) the effects of fully implemented RTI frameworks. Although RTI research may be expensive and difficult to implement, it may contribute to improved reading outcomes for many students who are otherwise at risk of serious negative life consequences.     

Specific Learning Disabilities and the Portuguese Educational System

Although the Portuguese educational system advocates the accommodation of all students in regular schools, it has not adopted a coherent discourse that would contribute to meeting effectively the needs of students with specific learning disabilities (SLD). As such, the successive reorganizations of special education have resulted in uninformed decisions that have caused the education of students with SLD in Portugal to be, in many instances, detrimental to their academic and social growth. We describe the reality of SLD in Portugal, considering four main topics: (1) the establishment of the SLD concept, (2) the birth of a Portuguese definition of SLD, (3) the context of educational policy, and (4) the provision for students with SLD.     

Accelerating chronically unresponsive children to tier 3 instruction: what level of data is necessary to ensure selection accuracy?

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.     

Joined up thinking? Evaluating the use of concept‐mapping to develop complex system learning

In the physical and natural sciences, the complexity of natural systems and their interactions is becoming better understood. With increased emphasis on learning about complex systems, students will be encountering concepts that are dynamic, ill‐structured and interconnected. Concept‐mapping is a method considered particularly valuable for enabling learning in subject areas that are complex or ill‐structured. Evaluations of concept‐mapping tend to reflect their many applications. Many evaluations that try to measure enhancements in learning use test scores or grade‐point averages as performance indicators, which provide little information on how cognitive processes have developed. In this study, a modification of the Biggs and Collis’ Structure of the Observed Learning Outcomes (SOLO) taxonomy is applied to measure differences in the cognitive and structural complexity of learning outcomes between groups of students who participated in a concept‐mapping activity with those from a cohort that did not. The evaluation demonstrated that the intervention was effective in enabling the great majority of students to achieve better connectivity in thinking, though improvements in overall performance were less significant. Almost all students perceived the intervention to be of value to their learning.     

Evaluation of a tangible mobile application for students with specific learning disabilities

Students with specific learning disabilities (SLD) typically do not perform at the expected levels of academic achievement. Tangible mobile applications are learning devices that allow for physical engagement and multisensory interaction. They present as promising tools to facilitate learning for students with SLD. This study explored the use of a tangible mobile application for assisting three seventh-grade Turkish students with SLD to learn scientific principles regarding cell concepts. A multiple-probe design across participants was used to examine the effectiveness of a tangible mobile application. In addition, issues related to usability of the application were also explored. The overall results of the study showed that the tangible mobile application was effective, and the students with SLD were willing to use this application, enjoyed the process, and used the application and objects easily/correctly.     

One size still does not fit all in specific learning disability assessment across ethnic groups

The use of IQ scores and discrepancy formulas for identifying specific learning disabilities (SLD) has been widely discredited by prominent researchers for more than a decade. Nevertheless, the overwhelming majority of state policies still specify the use of discrepancy formulas, including the simple difference method, which is psychometrically inferior to regression-based methods. This study compares the use of a minimum IQ cutoff score and a simple difference method versus a regression-based method for identifying SLD in a sample of African American and European American full-time college students (N = 117). Replicating the findings from previous studies using typically achieving children, typically achieving adults, and school-age children with SLD, this study adds to the chorus of voices criticizing the use of outdated assessment practices that can have deleterious effects for individuals with SLD. The implications for legislative policy are discussed in the context of the historical overrepresentation of African Americans in all special education categories except SLD and the increased access to higher education that students with SLD have gained during the past decade.     

Differential Ability Scales – Second Edition (neuro)psychological predictors of math performance for typical children and Children with Math Disabilities

Concerns about the ability‐achievement discrepancy method for specific learning disability (SLD) determination led to alternative research‐based methods, such as failure to respond to intervention. Neither of these regulatory methods address the statutory SLD definition, which explicitly includes a deficit in basic psychological processes. Examining neuropsychological processing differences among typical children and children with math SLD, commonality analyses revealed that Differential Ability Scales – Second Edition (DAS‐II) predictors accounted for more achievement variance in typical children (46% to 58%) than in children with math SLD (33% to 50%), with substantial loss of predictive validity when General Conceptual Ability was used instead of subcomponent scores. Results suggest that differences in typical predictor‐outcome relationships may provide a foundation for developing specific cognitive and academic interventions for children with math SLD. © 2008 Wiley Periodicals, Inc.
