Researchers determined virtual manipulatives, on their own or as part of an instructional sequence, to be an evidence-based practice for students with intellectual and developmental disabilities (IDD; Long et al., 2022). Yet, the majority of research looking at virtual manipulative-based instructional sequences involves the phases learned in a…

The current study examined the effectiveness of a reading curriculum of explicit instruction on the letter-sound knowledge of a sample of elementary-aged students with Down syndrome. The procedures were adapted from prior research (King et al., 2020; Lemons et al., 2018; Lemons et al., 2015). Three participants between 9 and 11 years old…

The purpose of this study was to examine the effects of an online, multi-component intervention (video modeling, online mathematical games, self-monitoring checklists, and least to most prompting) in teaching mathematics skills to autistic secondary school students using a multiple probe design across skills. This study is unique from previous…

Research has established that implementing evidence-based practices with a high procedural fidelity is integral in promoting positive outcomes for students with moderate-to-severe disabilities and more significant support needs. However, special education teachers who teach students with moderate-to-severe developmental disabilities often lack…

This paper presents information from a comprehensive review of 28 experimental studies that investigated the effectiveness and efficiency of the simultaneous prompting procedure with individuals with autism. Twenty of the 25 variables examined across the 28 studies are reported on in this paper. The results reported across the studies indicated…

The present study evaluated a systematic instructional package including the system of least prompts (SLP) to teach differentiation and selection of tangible symbols to continue activities for two children with complex support needs and deafblindness (DB). A multiple probe design across three symbols was used to evaluate the intervention package…

A single subject multiple probe design across participants was used to examine the effects of distributing trials in shared stories on listening comprehension and skill acquisition with students with significant cognitive disability (SCD). The results suggest a functional relationship between the independent and each of the dependent variables. In…

Conceptual model-based problem solving (COMPS) was tested for its efficacy in teaching a student diagnosed with autism spectrum disorder to solve word problems involving multiplication and division. A single-case, multiple-baseline across behaviors design was conducted. The ability to solve each of three types of multiplication problems examined…

Mathematics education highlights the importance of helping students understand mathematical content and the ability to think critically about mathematics. Mathematical practice standards outline expectations for engaging students in meaningful mathematics activities to encourage a deep understanding of mathematical concepts and content. For some…

The global COVID-19 pandemic forced teachers to support students online in multiple academic subjects, including mathematics, including students with disabilities and those at-risk. And yet, to date, limited research exists examining teaching mathematics to students with disabilities online. The current study explored the use of the…

There is a lack of research and program development in the area of sexuality education for those with autism spectrum disorder (ASD). The prevalence of ASD is on the rise, and research demonstrates that individuals with ASD desire romantic and sexual relationships. It is important that programming targeting sexuality education for individuals with…

Word problem solving skills include complex skills. Teaching word problem solving skills to students with disabilities is more difficult compared to their peers with typical development. Therefore, effective interventions need to be determined in order to teach these skills to students with disabilities. The purpose of this study is to analyze the…

One intervention that has been evaluated in numerous empirical investigations and has been implemented clinically is Social Stories. Social Stories are a systematic form of intervention where a text is written describing a situation (e.g., social situation) and how the learner should respond during that situation. Previous reviews and analysis…

Mathematics is an important but also under-explored area of education for students with disabilities, including middle school students with intellectual and other developmental disabilities. In this study, researchers taught middle school students with intellectual and developmental disabilities (IDD) to solve word problems grounded in life skills…

This systematic review provides a synthesis of intervention research that taught mathematical word problem solving skills to students with autism spectrum disorder between 1975 and April of 2020 by evaluating the body of research in terms of "what works", "for whom" and "under what conditions". The Council for…
