Teaching Students With Mild Intellectual Disability to Solve Word Problems Using Schema-Based Instruction

This study, which used a multiple baseline across students’ design, examines the effectiveness of a modified schema-based instructional approach to improve the mathematical word problem-solving performance of three students with mild intellectual disability, two of them with autism spectrum disorder. Following the intervention, the three students improved their performance when solving addition and subtraction change word problems; however, their performance was inconsistent with change word problems. The effects of the instruction were generalized to two-step addition and subtraction word problems for the three participants. Moreover, the results were generalized to an untrained setting and were maintained 8 weeks after the instruction. The implications of these findings for teaching problem-solving skills to students with intellectual disability are discussed.

Practical Use of Single-Case Research Design to Target Improved Behavioral Outcomes for Students With SLD

Intensive academic interventions help address the learning difficulties of students with specific learning disabilities (SLDs). Challenging behaviors exhibited during instruction can have a negative impact on the overall effectiveness of an academic intervention. In addition to academic interventions, students with SLD may benefit from behavioral interventions. One method for evaluating the effect of interventions that target improved behavioral outcomes for students with SLD is single-case research designs (SCRDs). This article provides an overview of critical features of SCRD studies evaluating behavioral interventions with students with SLD or interventions with teachers of students with SLD. The article also examines how research decisions were made to support other researchers’ development of high-quality SCRD studies.

More Than Words: Anxiety, Self-Esteem and Behavioral Problems in Children and Adolescents With Dyslexia

This study focused on psycho-affective and behavioral problems in children and adolescents with dyslexia. It aims to define clinical psycho-affective and behavioral profiles of dyslexia beyond those found in existing descriptions of the cognitive, neural, and behavioral correlates. The study focused specifically on the understudied population of native Italian-speaking students. Characteristics of anxiety and self-esteem, as psycho-affective factors, and a variety of associated behavioral problems were studied in a sample of children and adolescents with dyslexia ( n = 22) and compared to those of a group without learning disabilities ( n = 25). The findings suggest the group of participants diagnosed with dyslexia exhibited psycho-affective symptoms, especially anxiety and low self-esteem in social, and academic situations more frequently than the control group. These problems were related to reading measures. More research is needed to determine how they are related and their interaction. Overall, these findings are useful in clarifying the profile of psycho-affective symptoms in the development of academic difficulties in children and adolescents with dyslexia. In some cases, school personnel focus their interventions only on the academic difficulties and not the psycho-affective or behavioral problems. These findings could have implications regarding intervention for this population.

Using Video Modeling, Explicit Instruction, and Augmented Reality to Teach Mathematics to Students With Disabilities

Students with exceptionalities who do not make adequate progress with core instruction in mathematics require more intensive research-based interventions such as explicit instruction or video modeling to address instructional needs. This study examined the effects of combining point-of-view video modeling, explicit instruction, and augmented reality to teach mathematics to students with disabilities. The researchers employed a multiple baseline across skills, single-subject research design, to evaluate the effects of the intervention on student performance across four mathematics skills. Two eighth grade students identified as having a disability impacting mathematics, one with autism spectrum disorder and one with a specific learning disability, participated in the study. Visual analysis determined a functional relation between the dependent and independent variables. Tau-U result for the intervention phase was 1.0 across all four skills for each participant. Participants demonstrated high levels of maintenance, and with one exception, students were able to apply the skills to word problems without additional training. Limitations and implications for future research and practice are discussed.

Word- and Text-Level Reading Difficulties in Students With Dyslexia

The purpose of this study was to examine whether group-based differences exist in word- and text-level reading in a clinical sample of students with dyslexia, and to shed light on the cognitive processes supporting these essential skills. Second- through seventh-grade students were administered a battery of standardized measures of cognitive processing skills (phonological awareness, rapid automatized naming [RAN], and verbal short-term memory), word reading skills (decoding and word identification), oral text reading (fluency and comprehension), and silent text reading (fluency and comprehension). Word- and text-level reading skills were used to place students into the following groups: text fluency deficit, globally impaired, and partially remediated. Results replicated the existence of a text fluency deficit group. Reader group differences in terms of cognitive processing skills were less pronounced than expected, with only phonological awareness differentiating among them. Phonological awareness and RAN emerged as the important contributors to reading skill, though their relative contributions varied across wordand text-level measures. Together, these results point to importance of considering text-level reading processes across modality in both research and clinical contexts.

Current Research Informing the Conceptualization, Identification, and Treatment of Dyslexia Across Orthographies: An Introduction to the Special Series

This introduction to the special series summarizes evidence for the genetic and brain bases for dyslexia and cognitive–behavioral indicators (including ones that can be measured even before the onset of reading instruction) that attest to meaningful differences between children with dyslexia and their non-dyslexic peers. Authors review controversies that have surrounded approaches to dyslexia identification and treatment during the last few decades. Finally, they introduce the findings of the articles in the special series and discuss potential implications for dyslexia identification and treatment.

Ecological and Population Validity of Mathematics Interventions for Diverse Students With Low Mathematics Achievement: A Meta-Analysis

This meta-analysis examined the ecological and population validity of intervention research for students with low mathematics achievement (SWLMA). Forty-four studies published between 2005 and 2019 that met the inclusionary criterion were included in this analysis. Our findings suggest, to improve the external validity and generalizability of research, more detailed descriptions of participants and the socio-cultural contexts of the intervention studies are warranted.
