Responsiveness‐to‐Intervention: Definitions, Evidence, and Implications for the Learning Disabilities Construct

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.

Is There a Bidirectional Relationship between Children's Reading Skills and Reading Motivation?

Young children who enjoy reading do it more often and they tend to become skilled at it. Poor readers, by contrast, often display low motivation to read. One possible explanation of this is that reading skill and reading motivation influence each other. 15 studies were reviewed addressing the relationship between young childrens reading and competency beliefs or goal orientations. Results indicate that reading skills and motivation correlate (albeit moderately), and support the possibility of a bidirectional relationship between the two. Researchers, practitioners, and parents may need to target both reading skill and motivation to best help poor readers become proficient.

Examining the Influence of Teacher Behavior and Classroom Context on the Behavioral and Academic Outcomes for Students With Emotional or Behavioral Disorders

Many students with emotional or behavioral disorders (EBD) display both learning and behavioral problems that make it difficult for teachers to provide effective instruction. In turn, a lack of exposure to effective instruction contributes to poor academic and behavioral outcomes. In this article, the authors argue that the interaction between the learning and behavior problems of students with EBD is complex and likely characterized by multiple influences, including classroom contextual factors. The authors detail (a) ways that teacher instructional behaviors and classroom contexts may contribute to the relationship between learning and behavior problems of students with EBD and (b) assessment procedures helpful for measuring classroom contextual variables. Implications for future research are discussed, including using data gleaned from applied research to inform future randomized clinical trials examining classroom-based interventions for students with EBD.

Five-Year Growth Trajectories of Kindergarten Children With Learning Difficulties in Mathematics

The investigators used data from the Early Childhood Longitudinal Study—Kindergarten Cohort (ECLS-K) to estimate whether and to what extent the timing and persistence of mathematics difficulties (MD) in kindergarten predicted childrens first through fifth grade math growth trajectories. Results indicated that children persistently displaying MD (i.e., those experiencing MD in both fall and spring of kindergarten) had the lowest subsequent growth rates, children with MD in spring only had the second-lowest growth rates, and children with MD in the fall only (and who had thus recovered from their MD by the spring of kindergarten) had the next-lowest growth rates. The children who did not have MD in either fall or spring of kindergarten had the highest growth rates. These results were observed prior to and after statistical control for additional variables. They indicate that measuring the timing and persistence of kindergarten childrens mathematics learning difficulties may help identify those most at risk for failing to become mathematically proficient during elementary school.

Are Reading and Behavior Problems Risk Factors for Each Other

Two questions were investigated. First, are children with reading problems in first grade more likely to experience behavior problems in third grade? Second, are children with behavior problems in first grade more likely to experience reading problems in third grade? The authors explored both questions by using multilevel logistic regression modeling to analyze data from the Early Childhood Longitudinal Study—Kindergarten Class (ECLS-K). After statistically controlling for a wide range of potential confounds, they found that children with reading problems in first grade were significantly more likely to display poor task engagement, poor self-control, externalizing behavior problems, and internalizing behavior problems in third grade. They also found that children displaying poor task engagement in first grade were more likely to experience reading problems in third grade. Collectively, these findings suggest that the most effective types of interventions are likely to be those that target problems with reading and task-focused behaviors simultaneously.

WHO IS PLACED INTO SPECIAL EDUCATION

The authors use nationally representative data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (ECLS-K) to identify variables measured in the fall of 1998 (when the sample’s students were in kindergarten) that predict special education placement by the spring of 2004 (when most students were finishing fifth grade). Placement’s strongest kindergarten predictor is a student’s level of academic achievement. Also important is the student’s frequency of classroom task engagement. There is a “frog-pond” contextual effect—attending an elementary school with high levels of overall student academic ability and behavior increases a student’s likelihood of special education placement. This is the case even after statistically controlling for a wide range of individual-, family-, and school-level characteristics. Social class background displayed a weak or statistically nonsignificant relation with special education placement. However, girls are placed less frequently than boys. African American, Hispanic, and Asian students are placed less frequently than non-Hispanic whites. The under- or equal-placement rates for racial/ethnic minorities are partially explained by their concentration in high-minority schools.

Does Early Reading Failure Decrease Children's Reading Motivation?:

The authors used a pretest—posttest control group design with random assignment to evaluate whether early reading failure decreases childrens motivation to practice reading. First, they investigated whether 60 first-grade children would report substantially different levels of interest in reading as a function of their relative success or failure in learning to read. Second, they evaluated whether increasing the word reading ability of 15 at-risk children would lead to gains in their motivation to read. Multivariate analyses of variance suggest marked differences in both motivation and reading practice between skilled and unskilled readers. However, bolstering at-risk childrens word reading ability did not yield evidence of a causal relationship between early reading failure and decreased motivation to engage in reading activities. Instead, hierarchical regression analyses indicate a covarying relationship among early reading failure, poor motivation, and avoidance of reading.

A Propensity Score Matching Analysis of the Effects of Special Education Services

We sought to quantify the effectiveness of special education services as naturally delivered in U.S. schools. Specifically, we examined whether children receiving special education services displayed (a) greater reading or mathematics skills, (b) more frequent learning-related behaviors, or (c) less frequent externalizing or internalizing problem behaviors than closely matched peers not receiving such services. To do so, we used propensity score matching techniques to analyze data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998—99, a large-scale, nationally representative sample of U.S. schoolchildren. Collectively, results indicate that receipt of special education services has either a negative or a statistically nonsignificant impact on children’s learning and behavior. However, special education services do yield a small, positive effect on children’s learning-related behaviors.

Kindergarten Children’s Growth Trajectories in Reading and Mathematics: Who Falls Increasingly Behind?

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.

Racial and Ethnic Disparities in ADHD Diagnosis From Kindergarten to Eighth Grade

OBJECTIVE: Whether and to what extent racial/ethnic disparities in attention-deficit/hyperactivity disorder (ADHD) diagnosis occur across early and middle childhood is currently unknown. We examined the over-time dynamics of race/ethnic disparities in diagnosis from kindergarten to eighth grade and disparities in treatment in fifth and eighth grade. METHODS: Analyses of the nationally representative Early Childhood Longitudinal Study, Kindergarten Class of 1998–1999 (N = 17 100) using discrete-time hazard modeling. RESULTS: Minority children were less likely than white children to receive an ADHD diagnosis. With time-invariant and -varying confounding factors statistically controlled the odds of ADHD diagnosis for African Americans, Hispanics, and children of other races/ethnicities were 69% (95% confidence interval [CI]: 60%–76%), 50% (95% CI: 34%–62%), and 46% (95% CI: 26%–61%) lower, respectively, than for whites. Factors increasing children’s risk of an ADHD diagnosis included being a boy, being raised by an older mother, being raised in an English-speaking household, and engaging in externalizing problem behaviors. Factors decreasing children’s risk of an ADHD diagnosis included engaging in learning-related behaviors (eg, being attentive), displaying greater academic achievement, and not having health insurance. Among children diagnosed with ADHD, racial/ethnic minorities were less likely than whites to be taking prescription medication for the disorder. CONCLUSIONS: Racial/ethnic disparities in ADHD diagnosis occur by kindergarten and continue until at least the end of eighth grade. Measured confounding factors do not explain racial/ethnic disparities in ADHD diagnosis and treatment. Culturally sensitive monitoring should be intensified to ensure that all children are appropriately screened, diagnosed, and treated for ADHD.
