The use of standard scores in diagnosing learning disabilities: A critique

This paper examines the limitations of standard scores of achievement tests commonly used in diagnosing learning disabilities. The consideration of these limitations is an important factor in attempting to decide whether a marked discrepancy exists between ability and achievemen, a requirement for the diagnosis of learning disabilities under Public Law 94–142. The phrase “standard score scale” is ambiguous because it can refer to both status score scales and developmental score scales. Unfortunately, many school psychologists seem unaware of the distinction between these two types of standard scores and the ramifications of this distinction. Many standardized achievement tests commonly used in the assessment of learning disabilities use status standard scores despite their severe limitations (noncomparability across grade levels and subjects, and failure to reflect changes in variability across grade levels). While developmental standard scores are to be preferred over status standard scores in diagnosing learning disabled children, their value is significantly lowered because they require greater growth for below-average students than for average or above-average students. Moreover, developmental scores are nonequal interval and they assume that subject matter is normally distributed within age or grade groups. Although we recommend the use of developmental standard scores over status standard scores, we urge that they be interpreted cautiously.     

Differential ability scales: Profiles of preschoolers with cognitive delay

This study examined the cluster profiles obtained using the Differential Ability Scale (DAS, Elliott, 1990a) for preschool children diagnosed with cognitive delay and for those without cognitive delay. Cluster analyses resulted in distinctive profiles for each group. Profiles for preschoolers diagnosed with cognitive delay were compared with DAS profile patterns previously reported for school‐aged children diagnosed with learning disabilities (McIntosh & Gridley, 1993). Cluster comparisons indicated profiles of cognitively delayed preschoolers were not the same as those found in school‐age children with learning disabilities. Implications for prediction of school‐age learning disabilities from preschool DAS cognitive cluster profiles are discussed. © 2002 John Wiley & Sons, Inc.     

Promoting Prosocial Behaviours Among Preschool Children With and Without Disabilities

A multiple probe across subjects design was used to evaluate the effectiveness of an intervention program on promoting prosocial behaviours among preschool children with and without disabilities. The intervention was carried out with three integrated groups of children, each comprised of one child with a disability and two peers without disabilities, created from three mainstreamed preschool classrooms. The intervention was successful in promoting increases in positive social interactions among the children with disabilities and their peers without disabilities. For two of the three groups the children with disabilities engaged in an equal or greater percentage of positive social initiations than their peers without disabilities. Increases in positive social responses to positive social initiations were similar for children with and without disabilities. Intervention phase behavioural changes generalised to both immediate group conditions, but did not generalise to deferred classroom conditions. Variability of response to intervention across groups highlights the need to develop and implement interventions on an individualised basis. The results indicate that further research is needed regarding the promotion of deferred generalisation effects as well as understanding the effects that trainer presence may have on the generalisation of the targeted social behaviours. There is also a need for the investigation of the potential for gender‐related effects including differential activity levels, ability for sustained attention, and group composition.     

Learning in Early Intervention Programs: The Generalization and Maintenance of IEP Objectives

This study investigates the maintenance and generalization of preacademic objectives in children with mental retardation from early intervention programs. All the subjects (25) had mastered, according to their Individual Education Programs (IEPs), at least one task in the areas of color, shape, number, or big/little . They, along with children in three comparison groups, were given a series of tasks that included the same previously achieved IEP objectives (maintenance) and closely related tasks within the same domain (generalization). The findings indicated variability in maintenance and generalization for the children in early intervention, better for color and shape than for number and big/little. Success on generalization was below the usual standard indicating mastery (85%-100%). On the generalization tasks, children in early intervention performed similarly to older children with retardation who had lower standard scores (Peabody Picture Vocabulary Test-Revised) but roughly equivalent language ages. They performed less well than older children with retardation who had similar standard scores but higher language ages. They also performed less well than children without disabilities in regular preschool programs who were close in chronological age, but had higher standard scores and higher language ages. We conclude that performance on these tasks is closely tied to developmental age regardless of chronological age and "IQ" status. Findings are discussed in relationship to preacademic curriculum in early intervention programs.     

Swiss Children's Moral and Psychological Judgments About Inclusion and Exclusion of Children With Disabilities

Children's judgments about inclusion and exclusion of children with disabilities were investigated in a Swiss sample of 6‐, 9‐, and 12‐year‐old children from inclusive and noninclusive classrooms (N = 422). Overall, the majority of children judged it as morally wrong to exclude children with disabilities. Yet, participants were less likely to expect the inclusion of children with mental or physical disabilities in academic and athletic contexts compared to social contexts. Moreover, older children more consistently coordinated disability type with context of exclusion. There were also significant differences depending on the type of classroom. The findings extend existing research on exclusion by investigating exclusion based on disability across different age groups and educational settings.     

A Developmental Comparison of the Out‐of‐school Recreation and Leisure Activity Participation of Boys and Girls With and Without Physical Disabilities

Similarities and differences were examined in the out‐of‐school recreation and leisure activity participation of 422 children with physical disabilities and 354 children without disabilities. The roles of age (six to eight years, nine to 11 years, and 12–14 years), gender, and disability status were examined with respect to the diversity, intensity, location, companionship, and enjoyment of participation in five types of activities, controlling for family income. The findings indicate that dimensions and types of activity participation are differentially influenced by age, gender, and disability. Age cohort comparisons indicated that children without disabilities experienced a widening social world characterised by more intense social participation, greater participation with non‐family members, and stable levels of enjoyment across the age groups. In contrast, children with disabilities in the various age groups were similar in their intensity of social participation and the nature of their companionship, with 12–14 year olds reporting less enjoyment of social activities than those aged six to eight years or nine to 11 years. The findings support the utility of a developmental and contextual perspective in understanding children’s patterns of participation. The information can be used by service providers and managers interested in creating centre‐based or community‐based recreational opportunities, and in providing information to parents about how to encourage children’s recreation and leisure participation.     

Methodological issues and learning disabilities diagnosis in clinical populations.

Previous research suggests that the diagnosis of a comorbid learning disability is dependent on the method used for making the LD diagnosis. This study investigated that proposition by studying the effects of using three approaches to the assessment of learning disabilities in a sample of 177 six- to thirteen-year-old boys referred to outpatient mental health clinics for behavior problems. The use of these three procedures to diagnose comorbid learning problems produced significantly different results. All methods identified significant numbers of children in the clinical population as learning disabled; however, each method identified children with differing characteristics. Consistent with predictions from measurement theory, the commonly used simple standard score discrepancy method was more likely to identify children with above-average IQs as learning disabled, whereas a regression approach identified learning disabilities more consistently across the ability range. These results were interpreted as supporting the use of regression approaches to diagnose co-occurring learning disabilities, as that method is less likely to be biased by the child's intelligence test score. The implications of the use of each method in research investigations is also discussed.     

Selecting gifted children with the Slosson Intelligence Test: 1981 vs. 1961 norms

The Slosson Intelligence Test (SIT) for Children and Adults protocols for 683 gifted students ranging in age from 6 to 12 years were scored using both 1961 and 1981 norms. The average 1981 norm score was 5.17 points lower than the 1961 norm score. The differences increase with the age of the child. Implications for using the SIT for selecting gifted children are discussed.     

Assessing Early Language Development in Children with Vision Disability and Motor Disability

This article describes a method for identifying test items as disability neutral for children with vision and motor disabilities. Graduate students rated 130 items of the Preschool Language Scale and obtained inter‐rater correlation coefficients of 0.58 for ratings of items as disability neutral for children with vision disability, and 0.77 for ratings of items as disability neutral for children with motor disability. These ratings were used to create three item sets considered disability neutral for children with vision disability, motor disability, or both disabilities. Two methods for scoring the item sets were identified: scoring each set as a partially administered developmental test, or computing standard scores based upon pro‐rated raw score totals. The pro‐rated raw score method generated standard scores that were significantly inflated and therefore less useful for the assessment purposes than the ratio quotient method. This research provides a test accommodation technique for assessing children with multiple disabilities.     

Impact of an Early Reading First program on the language and literacy achievement of children from diverse language backgrounds

This study used an age-cutoff regression discontinuity design to examine the impact of a well-resourced Early Reading First prekindergarten program designed to foster the language and literacy development of 4-year-old children from low-income homes. A special challenge for the application of the language-rich curriculum and professional development package implemented in this study was the presence of a large proportion of ELL children in essentially English-speaking classrooms. We, therefore, sought to determine whether the program was effective for improving English language and literacy outcomes for English-language learners as well as native English speakers. There were large and significant differences between treatment and control groups on literacy outcomes for all students. On the literacy tasks, ELL students in the treatment groups performed nearly as well or better than non-ELL students at the beginning of kindergarten, and reached national norms on standardized tests. There were also significant program impacts on some language outcomes for all students. ELL students who received the intervention significantly outperformed ELL students in the control groups on English receptive and expressive vocabulary. On the more complex oral comprehension skills, preschool did not have a significant impact for ELL students. Intervention effects on receptive vocabulary and oral comprehension for native speakers were found only for the third cohort and were not found for expressive vocabulary. These results provide evidence that, given material supports, coaching, professional development, and the use of a language and literacy-focused curriculum, prekindergarten classrooms can enable low-SES children from diverse language backgrounds to enter kindergarten with literacy skills at or near national norms and can significantly impact some language skills. While non-native speakers of English continued to score lower on language measures than their native-speaking peers, results show that 1 year of preschool can put all children on a positive trajectory for long-term success in school.     

Phonological Awareness,Peer Nominations,and Social Competence Among Preschool Children At Risk for Developing Learning Disabilities

This study examined the relations between phonological awareness skills and social-emotional competence among preschool children who were considered at risk for developing learning disabilities. Phonological awareness skills, loneliness, sense of coherence, and peer acceptance of 98 children with an age range from 5.0 to 6.4 years (39 with a high risk for developing learning disabilities and 59 nondisabled peers) were assessed. The children at risk differed significantly from the nondisabled children on all measures. Their scores on the phonological awareness measures were lower, they viewed themselves as more lonely, felt less confident about their world, and they were less accepted by their peers. Subgrouping, using the sense of coherence and the combined phonological measure as criteria, revealed that the largest number of children at risk were in the group with lowest levels of coherence and phonological awareness skills. The smallest proportion of high risk children was found in the group characterised by its high sense of coherence and high level of phonological awareness. Thus, children at risk for developing learning disabilities revealed two groups of deficits: phonological awareness difficulties and social-emotional difficulties. The results emphasised the need to examine interrelations between peer acceptance and both cognitive-phonological awareness and emotional domains.     

THE INFLUENCE OF VYGOTSKY IN MOVIMENTO DA ESCOLA MODERN A EARLY CHILDHOOD EDUCATION CURRICULUM IN PORTUGAL

Abstract

The present study investigated specific teacher factors that potentially influence teacher‐child relationships with preschool‐age children. One demographic questionnaire and three rating scales were used to survey 152 head teachers of 3–6‐year‐old children in community‐based childcare and preschool centers in one mid‐western state. There were 46 teachers who reported on their relationship with a child with a disability or concerning developmental delay. Positive correlations were found between teacher‐child relationships and the teachers’ educational backgrounds, self‐reported teaching efficacy and parent‐teacher relationships. The parent‐teacher relationship appeared to be the strongest teacher‐related factor predicting the quality of teacher‐child relationships. Compared to other teachers, the teachers of children with delays or disabilities reported comparable parent‐teacher relationships and more positive teacher‐child relationships, especially when more than one child with concerns was reportedly enrolled in the classroom. Teachers with children who had developmental delays reported lower teaching efficacy scores. The role of parent‐teacher relationships is highlighted as a possible moderator when teachers feel less than capable or positive about individual children in their program.     

Investigation and comparison of Turkish and American preschool teacher candidates’ attitudes towards inclusion of young children with disabilities

Inclusion of young children with disabilities into general education classrooms is a common practice that has been implemented for many years in developed countries around the world and many developing countries have been creating and implementing laws and regulations to support inclusive education in early years. Although extant literature includes a commonly agreed definition for inclusion, the implementation of inclusive practices varies across countries. A critical factor for successful implementation of inclusive practices is teachers’ attitudes towards inclusion of children with disabilities. The purpose of this study was to compare Turkish and American pre-service preschool teachers’ attitudes towards inclusion of young children with disabilities and their willingness to work with children with severe behavioural, physical, and cognitive disabilities. A total of 123 pre-service teachers participated in the study. The results showed that pre-service teachers across two countries had similar attitudes towards inclusion and their attitudes were positive. Additionally, both groups of pre-service teachers reported more favourable attitudes towards working with children with severe physical disabilities than those who have severe cognitive and behavioural disabilities. Implications for future research and practices are discussed.     

Exploring the effects of a social communication intervention for improving requests and word diversity in preschoolers with disabilities

This study examined the effects of a multicomponent social communication intervention to promote language learning and peer‐directed social interactions in preschool children with disabilities. Participants were eight children with developmental disabilities who met the specified criteria for the study. The intervention consisted of three components: (a) a planning period for instructional purposes, (b) a play session to practice skills, and (c) a brief reporting period to review skill performance. A multiple baseline design across two dyads replicated across two additional dyads was used. Results indicated an increase in peer‐directed requests, verbal requests, and word diversity for 6 of the 8 participants postintervention. Implications of the results are discussed. © 2008 Wiley Periodicals, Inc.     

Demonstration of Classroom Survival Skills in Kindergarten: A five-year transition study of children with intellectual disabilities

Thirty-three children with a range of intellectual disabilities who participated in a transition program embedded within a model inclusive preschool program were enrolled in mainstream kindergarten classes from 1995 to 1999. In the second of four kindergarten terms the classroom survival skills, on-task behaviour across a range of activities and following teacher directions, were measured by observing the children with intellectual disabilities and a typical peer, nominated by each classroom teacher. While the teacher-nominated peers outperformed the students with intellectual disabilities in total time-on-task, the level achieved by the children with intellectual disabilities was still at the lower end of what is regarded as average. There was no statistical difference between the two groups in on-task behaviour during independent activities but the difference between the groups during whole class instruction was highly significant. This may have implications for the selection of strategies for preparing children for transition and the adaptation of teaching practices. On-task behaviour did not vary a great deal across level of intellectual disability but gender may have been a contributing factor. There appeared to be a greater difference between students with and without disabilities in responding to teacher directions. The results of the present study suggest that successful demonstration of these critical skills requires more appropriate teacher preparation and intervention at the kindergarten level.     

Children's Norm Enforcement in Their Interactions With Peers

This study investigates how children negotiate social norms with peers. In Study 1, 48 pairs of 3‐ and 5‐year‐olds (N = 96) and in Study 2, 48 pairs of 5‐ and 7‐year‐olds (N = 96) were presented with sorting tasks with conflicting instructions (one child by color, the other by shape) or identical instructions. Three‐year‐olds differed from older children: They were less selective for the contexts in which they enforced norms, and they (as well as the older children to a lesser extent) used grammatical constructions objectifying the norms (“It works like this” rather than “You must do it like this”). These results suggested that children's understanding of social norms becomes more flexible during the preschool years.     

JOINT CONFIRMATORY FACTOR ANALYSIS OF THE WOODCOCK‐JOHNSON TESTS OF COGNITIVE ABILITIES,THIRD EDITION,AND THE STANFORD‐BINET INTELLIGENCE SCALES,FIFTH EDITION,WITH A PRESCHOOL POPULATION

This study examined the underlying constructs measured by the Woodcock‐Johnson Tests of Cognitive Abilities, Third Edition (WJ‐III COG) and the Stanford‐Binet Intelligence Scales, Fifth Edition (SB5), based on the Cattell‐Horn‐Carrol (CHC) theory of cognitive abilities. This study reports the results of the first joint confirmatory factor analysis of the WJ‐III COG and SB5 with an independently collected preschool‐aged sample. The WJ‐III COG and SB5 were administered to 200 preschool‐aged children of 4 to 5 with no known disorders or disabilities. Confirmatory factor analyses using maximum likelihood estimation were conducted to evaluate three models of increasing complexity and two alternative models to determine which model best describe the underlying constructs measured by the WJ‐III COG and the SB5. Though none of the models displayed a good fit to the data, results showed that the underlying construct of the two tests was best represented by a Three‐Stratum alternative CHC model in which the Gf factor and subtests were omitted. Exploratory factor analysis was conducted to provide further insights into the actual latent structure underlying the data. Implications of findings to guide school‐based practitioners in using cross‐battery assessment with preschool children were addressed.     

Vignettes from Sesame Street: Preschooler's Ideas about Children with Down Syndrome and Physical Disability

The results of previous research suggest that while preschool children have a beginning understanding of disabilities that involve the use of adaptive equipment, they have little awareness of disabilities such as Down syndrome which have less overt distinguishing characteristics. In this study, videotaped segments from the children's television show, Sesame Street, were used to explore children's ideas about Down syndrome and physical disability. Participants included 41 preschool children. While a majority of participating children were aware that each child in the videotapes had some difficulties performing age-appropriate tasks, children had significantly fewer ideas about why the child with Down syndrome had this difficulty. Significantly more thought that the child with Down syndrome could do more “if he tried really hard” when compared with the child with a physical disability. These results are discussed in terms of children's developing understanding of disabilities and implications for using media to teach preschoolers about people with disabilities.
