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.     

Issues in the definition and diagnosis of learning disabilities: a perspective on Guckenberger v. Boston University

This article reviews issues related to the definition of learning disabilities in the context of the Guckenberger v. Boston University case. Four major questions are addressed: (a) Who is learning disabled? (b) How should learning disabilities be assessed? (c) Who is qualified to make a decision about whether or not an individual has a learning disability? and (d) What accommodations should be provided by a postsecondary institution and how should they be selected? Although these are complicated and difficult questions, it is possible to develop a simple, reasonable classification system for learning disabilities, and to conduct assessments based on a coherent and relevant set of achievement tests in which individuals who score below a cutoff are considered learning disabled. Scores on IQ tests are irrelevant and not useful and may even be discriminatory. The issues of decision making regarding learning disabilities and appropriate accommodations remain significant dilemmas for the field; resolution of these issues seems virtually impossible without agreement on appropriate procedures for the definition, identification, and assessment of learning disabilities.     

An investigation of the K-ABC,WISC-R,and W-JPB,part two,with learning disabled children

The purpose of this study was to examine the relationship of the Kaufman Assessment Battery for Children (K-ABC), the WISC-R, and the Woodcock-Johnson Psychoeducational Battery (W-JPB), Part Two, with children who experience learning disabilities. Correlational analyses were used to examine relationships among the WISC-R, K-ABC Mental Processing and Achievement scales, and the W-JPB Achievement scales. Thirty-four children with learning disabilities (mean age 8–11 years) received all three measures. Correlation coefficients indicated stronger and more consistent relationships between the WISC-R and W-JPB Achievement tests than between the K-ABC and W-JPB Achievement tests. Significant relationships between the WISC-R Full Scale IQ and the K-ABC Mental Processing Composite (MPC) revealed evidence of validity for this learning disabled sample. However, correlation coefficients among the K-ABC Achievement subtests and the W-JPB Achievement clusters indicated both convergent and discriminant validity. Thus, it is suggested that both the K-ABC MPC, for assessment of cognitive abilities, and the W-JPB Achievement clusters could be employed in discrepancy formulas for special education placement of children with learning disabilities.     

Excluding students with disabilities from the culture of achievement: the case of the TIMSS,PIRLS, and PISA

International tests of achievement narrowly measure specific academic subjects, but have larger educational policy implications. These tests come to summarize national education systems and are used in national and international discourse. However, students with disabilities are being entirely excluded from participation in the discourse of achievement. The Trends in International Mathematics and Science Study, Progress in International Reading Literacy Study, and Programme for International Student Assessment all actively exclude students with disabilities from being measured when the testing agencies set up ‘desired target populations’ and report out on testing participation. This exclusionary discourse establishes that students with disabilities do not belong in a culture of achievement and educational evaluation, which has an impact on policies concerning educational equity and maintains the oppression of low expectations. US policy requires that 95% of all students take achievement tests and be given reasonable accommodations. This paper concludes that international achievement tests should follow the same standard.     

The relationships between the motivational beliefs,course experiences and achievement among postgraduate students in Pakistan

While there is considerable literature concerning the relationship between student motivation and achievement, few studies have examined the relationship between student motivation, course experiences and academic achievement at the postgraduate level. This paper is based on the findings of the initial correlation analysis of the relationship between motivational beliefs and course experiences of 368 postgraduate students in five different subject areas enrolled in day and afternoon classes at a highly-ranked public university in Pakistan. A questionnaire was developed using scales from the Motivated Strategies for Learning Questionnaire and the Course Experiences Questionnaire to measure the motivational beliefs and course experiences of students. Academic achievement was measured using the achievement score in the courses in which the data were collected. The results of the study indicated that students' achievement scores were positively correlated with their self-efficacy for learning and negatively correlated with test anxiety, whereas the course-experience factor learning community was significantly correlated with achievement scores. Significant correlations were also found among almost all motivational beliefs and course experience factors.

Tourette syndrome and learning disabilities.

We reviewed the records of 42 consecutive cases of children with Tourette Syndrome (TS) who had IQs above 70, and contrasted the reading, reading comprehension, math, and spelling quotients with IQ scores to determine how many would meet criteria for a learning disability. The mean IQ of the 35 males and 7 females was 94.4 and was higher than the mean math score (82.8), spelling score (90.4), reading score (87.4), and reading comprehension score (85.3). Using a 1.5 standard deviation discrepancy, 51% met criteria for learning disability in at least one academic area; 21% had a 2-standard-deviation discrepancy. Children with TS frequently have learning disabilities, and assessment of academic achievement should be a routine aspect in the evaluation of such children.     

Visual discrimination of letter-like forms and its relationship to achievement over time in children with learning disabilities

The purpose of this study was to better understand whether visual discrimination abilities are related to reading intelligence and other achievement areas in children with learning disabilities and normally achieving children. Children with visual discrimination problems were identified using the Gibson letter-like visual discrimination task. This task was given to a large sample of children with learning disabilities as well as a sample of normally achieving children. All children were followed throughout elementary school. Results indicated that children with learning disabilities who had visual discrimination problems at 6 or 7 years of age performed more poorly in reading and general achievement over the elementary school years in comparison to the other children with learning disabilities and compared to normally achieving children. Discussion centers around the importance of this skill for reading.     

Effects of Cooperative Learning on the Academic Achievement of Students with Learning Disabilities: An Update of Tateyama‐Sniezek’s Review

This article reviews research published from 1990 to 2000 examining effects of cooperative learning strategies on the academic achievement of students with learning disabilities. The literature search is described. Fifteen studies are included in the review and are grouped according to the types of cooperative learning strategies that were examined. Sample characteristics, measures, findings, and effect sizes are reported in a table. Achievement outcomes are mixed. Cooperative learning strategies that incorporate individual accountability and group rewards are more likely to improve achievement of students with disabilities. However, design problems across the studies limit conclusions to be drawn about the efficacy of cooperative learning. More research is needed before it may be viewed as an effective strategy for students with disabilities.     

The effects of self-regulated learning training on community college students’ metacognition and achievement in developmental math courses

The effects of training in self-regulation on metacognition and math achievement were investigated. The participants were 116 community college students enrolled in developmental math courses. Students enrolled in 16 classrooms were randomly assigned to the treatment and control groups. Participants in the treatment group completed four self-regulated learning (SRL) exercises based on Zimmerman’s (2002) cyclical model. The exercises were completed weekly and repeated for a total of 3 weeks. During the last week of class, participants completed a final exam to measure math achievement as well as the metacognitive self-regulation and time/study environment management scales on the Motivated Strategies for Learning Questionnaire ([MSLQ], Pintrich, Smith, Garcia, & McKeachie, 1991). There were significant differences between the two groups, indicating that training in SRL improved math achievement and metacognitive skills assessed on both MSLQ scales. The findings suggested that training in SRL improves math achievement, metacognitive self-regulation and time/study environmental management skills of students enrolled in developmental math courses.     

The criterion-related validity of psychoeducational tests for actual reading ability of learning disabled students

Although norm-referenced educational tests are used widely to identify children with learning disabilities, there have been few studies examining how performance on these tests relates to actual classroom functioning. This study examines the criterion-related validity of a battery of six educational diagnostic and achievement tests for actual reading level of a group of 155 learning disabled students enrolled in grades 4 to 7 and a subgroup of 46 learning disabled students enrolled in grades 5 and 6. Stepwise multiple regression analysis revealed that six subtests from the battery accounted for over 70% of the variance in reading for the larger group. When type of reading curriculum used was controlled, five subtests accounted for over 76% of the criterion. The theoretical and applied implications of these results for diagnostic assessment are discussed.     

A FACET-FACTORIAL APPROACH TO THE CONSTRUCTION OF RATING SCALES TO MEASURE COMPLEX BEHAVIORS

The purpose of this study was to examine a technique for the development of performance rating scales to measure achievement in courses whose objectives require complex behaviors not easily measurable with paper and pencil achievement tests. A facet-factorial approach to rating scale construction was employed (i.e. the behavior was conceptualized as multidimensional and items for the scales were selected by employing factor analytical techniques) to construct scales to measure clarinet music performance. The three major results of the study were: 1) a thirty-item rating scale based on a six factor structure of clarinet music performance; 2) high inter-judge reliability estimates for both the total score (above .90) and the scale scores (above .60); and, 3) criterion-related validity coefficients greater than .80. Results of the investigation suggest that the facet-factorial approach can be an effective technique for the construction of rating scales to measure complex behavior such as music performance.

Understanding the ‘Lexia’ in dyslexia: A multidisciplinary team approach to learning disabilities

The historical roots of the IQ-achievement discrepancy definition of learning disability are discussed as a reference point for explaining why this definition came into being and why it is inadequate for dealing with the variety of learning and developmental disabilities that present in school settings. A proposal is offered and justified for defining learning disabilities on the basis of profiles for multiple developmental domains that affect learning. In this proposal, developmental dyslexia is differentiated from other learning disabilities. Developmental dyslexia is defined as uneven development (dissociation) between word reading and higher-level processes in the functional reading system. Dyslexics may struggle with word reading because of deficits in phonological processes, orthographic-phonological connections, and/or fluency (rate, automaticity, or executive coordination). The need for both national and international classification schemes for defining specific learning and developmental disabilities for the purposes of educational services and research is emphasized.

Learning disabilities as functions of familial learning problems and developmental problems

A family history of learning problems as provided on a specially designed questionnaire by maternal report was examined in families of 101 children with learning disabilities and 171 children without disabilities. Diagnoses of learning disabilities followed the U.S. Office of Education definition. Students were selected from the Special School District of St. Louis County and the Pattonville School District. A life history of developmental risk factors in the child subject was also examined in the same two groups. Learning disabilities were found to be strongly familial. In principle, the definition of learning disabilities excluded from the study children with problems attributable to child rearing, emotional, or motivational factors. The report of a family history of learning problems is therefore interpreted as consistent with, although not unequivocally supportive of, genetic factors as determinants. Among developmental factors, only male gender proved to have a significant association with learning disabilities.     

Instructional and curricular requisites of mainstreamed students with learning disabilities

The successful integration of students with learning disabilities into mainstream reading classes may require teachers to adapt instruction and curricula in major ways. In this article, we discuss the relation between the instruction prescribed by standardized commercial curricula and the reading achievement of mainstreamed students with learning disabilities and other low-performing nonhandicapped students. An instructional template designed to complement commercially published reading lessons is described and its effects on the reading achievement of mainstreamed students with learning disabilities examined. Next, the limitations of generic instructional procedures to rectify the deficiencies of mainstream curricular programs for students with greater-than-average instructional needs are reviewed. We conclude with a discussion of the complexity of educating instructively needy learners in mainstream settings and the significance of well-designed instruction.     

Longitudinal research on the behavioral characteristics of children with learning disabilities

This paper summarizes a program of research on the behavioral characteristics of children with learning disabilities (LD) compared to average achievers. Longitudinal studies over a 3-year period beginning in the first and second grades showed that children with LD, as a heterogeneous group, displayed a persistent pattern of maladaptive classroom behavior that distinguished them from average achieving peers and that was associated with continued underachievement over time. Subsequently, children with LD in the longitudinal sample were clustered into seven different subtypes that represented attention problems, conduct and classroom management problems, withdrawn-dependent behavior, and normal behavior. Although no differences in achievement were found initially between behavioral subtypes, children in the attention and conduct problem subtypes had poorer academic outcomes 3 years later compared to those in the withdrawn subtype and those who had no significant behavior problems. The collective findings from this research are discussed in terms of the developmental relationship between learning disabilities, attention disorders, and social/emotional problems, and implications are drawn for a greater focus on behavioral interventions in special education and prevention efforts in the early grades.
