Non-compliance is a challenge for practitioners serving children with and without disabilities. Many interventions have been developed to increase compliance. High-probability request sequences (HPRS), an antecedent-based intervention that is based on behavioral momentum theory, is one way to increase compliant behavior. HPRS includes the…

Patterns of strengths and weaknesses represent relatively novel methods for identifying specific learning disabilities (SLD) with proponents asserting that the incorporation of multiple sources of assessment data and professional judgment play a key role in their utility. In this study, we examined if the sequential presentation of assessment data…

The benefit of permanent prompts depends on the extent to which their use is generalized. Previous research has demonstrated both control by and efficacy of pictorial prompts (e.g., Phillips & Vollmer, 2012). The present studies similarly evaluated stimulus control by textual prompts. Six school aged children with intellectual disabilities…

Fractions are an important mathematical concept for elementary students. However, students with mathematics learning disabilities (MLD) struggle with learning fractions. Research has demonstrated that concrete-representational-abstract (CRA) instruction is an effective practice for students with learning and developmental disabilities. Here we…

Manipulative-based instructional sequences--including both concrete and virtual manipulative instructional sequences--are evidence-based or research-based mathematical interventions for students with disabilities. However, as options for manipulative-based instructional sequences increase, educators need support in deciding the best approach. In…

The development of conceptual multiplication knowledge will assist students in making progress within current mathematics standards. Previous research has shown the concrete-representational-abstract (CRA) sequence to be successful in teaching multiplication with regrouping with an emphasis on conceptual understanding while developing fluency and…

This practical guide for teaching numeracy to children with a developmental disability is based on core concepts from the landmark Mathematics Recovery® text Teaching Number (aka 'the green book') that have been adapted for children with developmental disabilities. It sets out key principles of teaching and learning underpinning an evidence-based…

Science content remains a commonly overlooked academic content area for students with severe disabilities, including ASD and ID, despite recent research. The purpose of this study was to evaluate the effects of systematic instruction, such as prompting and fading techniques, implemented during whole-group science instruction for students with both…

Algebra is the foundational mathematics course that students take as they begin their high school career and is often difficult for the average learner. In order for students with disabilities and those with mathematics difficulties to meet the high expectations of future mathematical courses, providing quality instruction by implementing…

For the purpose of this article within this special issue on Structured Literacy™, we were asked to address the code-focused skills of phonemic awareness and word reading. Findings from research studies converge to show that explicit and systematic instruction helps most students understand how speech sounds, or phonemes, map to letters and…

Introduction: This article demonstrates the effectiveness of the use of routine-based instruction for teaching sensorimotor-stage object-perception skills to students who have visual impairments (i.e., blindness or low vision) and severe intellectual disabilities. Method: Classroom teachers documented progress toward achievement of object…

Fractions are foundational concepts for more advanced mathematics as well as used throughout daily living, for all students, including students with disabilities. This study explored the virtual-abstract (VA) instructional sequence with regard to the acquisition and maintenance of fraction behaviors for three middle school students with mild…

Instructional technology plays a role in supporting access to and meaningful participation in general education curriculum for students with developmental disabilities in inclusive classrooms. In this study, two 18-year-old students with developmental disabilities received technology-supported instruction to assist with learning the content in…

Mathematics instruction -- and interventions to support mathematics teaching -- for students with intellectual disability is important yet underexamined. This study explored a graduated instructional sequence referred to as the virtual-representational (VR) as a mathematical intervention. Researchers taught four students with disabilities what…

This article investigates the sequential recall of manual alphabet letters by signing deaf adolescents under two presentation conditions: fingerspelling and the listing and ordering technique (LOT) of American Sign Language. Fingerspelling presents each letter in a manner similar to the spelling of spoken words: A letter is produced and then is no…
