Background: Phonological awareness is the ability to identify and manipulate the sounds of language. This is a crucial skill for reading and spelling development. However, students with intellectual disabilities (ID) often have difficulties in acquiring phonological awareness skills. Objectives: This study aimed to assess the impact of a digital…

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…

This study examines the effects of a working memory (WM) sensitive math intervention in students with learning disabilities (LD). The intervention aims to improve early mathematical competencies while accounting for weak cognitive resources through a reduced instructional design. These principles are considered to be effective for learning. Ten…

Learning prepositions is very important for students with an intellectual disability to engage in functional communication behaviors. In addition, it is important for the students with intellectual disability to engage in physical activity at school because they spend the majority of their waking hours during weekdays at school. One way to…

This study compares the effectiveness and efficiency of constant time delay (CTD) and simultaneous prompting (SP) to teach decoding and word reading to four students, 7 to 9 years of age, with intellectual disabilities (ID) in the mild to moderate range. An adapted alternating treatment design was implemented to assess the two methods. The results…

Modified schema-based instruction (MSBI) is a strategy to teach mathematical word problem solving to students with moderate and severe disabilities (MSD). In this comprehensive review, we explore the current state of research on MSBI to determine whether MSBI is an evidence-based practice (EBP) for students with MSD. We reviewed 12 studies, of…

This social validity study accompanied a 9-month randomized control trial that investigated the efficacy of an emergent literacy program, Early Literacy Skills Builder (ELSB), delivered in general education elementary classrooms to students with severe disabilities, including autism. The social validity research questions focused on (a) the social…
