Most students with complex support needs are taught in separate special education classrooms; one reason is teams that inappropriately use the intensity of support needs as the basis for placement in more restrictive placements. This study used Bayesian multilevel modeling to determine whether the intensity of student support needs predicted…

We used a single case concurrent multiple probe across participants design to evaluate the effects of a multi-component intervention package on the number of correct sentences used when writing about a story for three rural elementary students with intellectual or developmental disabilities and extensive support needs. The package was comprised of…

Historically, research exploring the literacy experiences of learners with intellectual and developmental disabilities (IDD) has prioritized systematic, multicomponent instruction that emphasizes the development of traditional reading and writing skills. However, this approach may inadvertently facilitate literacy gatekeeping and limit…

The purpose of this study was to further address the "for whom" in the question of the effectiveness of modified schema-based instruction (MSBI) to teach mathematical problem solving to students with intellectual and developmental disability by evaluating whether positive outcomes from prior research would be replicated with elementary…

Recess represents a rich opportunity for social development, but students with intellectual and developmental disabilities (IDD) often do not fully realize these benefits. In this systematic review, we review 37 experimental studies in which students with IDD received interventions designed to improve social outcomes at recess. Overall, these…

This study examined the effectiveness of a Derived Relational Responding (DRR) program in improving reading comprehension accuracy among upper elementary students without intellectual or developmental disabilities who struggle to meet grade-level reading standards. Addressing a gap in current interventions, the study investigated whether DRR,…

The purpose of the study was to compare the differential effects of response independent and response-dependent criteria used to determine when to increase to the next delay interval in the progressive time delay (PTD) procedure. An adapted alternating treatments design was used to evaluate the relative efficiency of three variations of the PTD…

Social deficits are often a core area of development for students in special education, thus schools are charged with providing social skills interventions. Although many strategies are available, few schools successfully employ evidence-based interventions for students with autism and related disabilities. A way to address these concerns while…

Background: In the United States, approximately seven million students are chronically absent from school each year. Students with disabilities are more likely to be chronically absent than students without a disability. Using the bioecological systems theory, this study examined the impact of individual developmental disabilities and disability…

Functional behavior assessment (FBA) is an integral component of treatment development for students with intellectual and developmental disabilities. The continuum of FBA methods includes indirect, direct, and functional analysis assessment methods. However, there is not a standard for the best approach to the FBA process. This evaluation compared…

Training functional living skills is crucial for students with intellectual and developmental disabilities (IDDs) because they are directly related to their independence. The aim of this study was to explore the effect of an augmented reality (AR)-based video prompting (VP) teaching model on the learning of functional living skills among…

Students qualifying for services under the Individuals with Disabilities Education Act may experience challenges meeting the socioemotional demands of the school environment, creating a need for targeted interventions that can be delivered within school settings. The current study used a mixed-methods approach to examine the efficacy of a 4-week…

Students with intellectual and developmental disabilities (IDD) are likely to experience writing challenges that can negatively impact their overall academic, vocational, and social success. The goals of this study were to determine what writing interventions have been used with students with IDD, how their writing skills have been measured, the…

This article is one of the first attempts to study the mechanisms of foreign language learning by children with DLD. We test the effectiveness of a cognate intervention aiming to enhance cross-linguistic awareness of Dutch-speaking primary-school pupils with DLD, as part of their English as a Foreign Language (EFL) curriculum. The participants…

In a multi-year randomized control trial, paraeducators received targeted coaching and professional development to implement an individualized intervention for elementary or middle school students with intellectual and developmental disabilities (IDD). Paraeducators in the study's two treatment conditions delivered an early literacy intervention…
