Developmental coordination disorder (DCD) affects 2-7 percent of school-age children and is characterized by low motor proficiency associated with poor balance, coordination and handwriting skills. Because of their motor difficulties, children with DCD suffer from anxiety, low self-esteem and are often less sociable than typically developing…

Increasingly, researchers have successfully identified strategies to promote comprehension to students who are nonreaders. Further research is needed to replicate these promising results. In the current study, we used a multiple probe across participants design to evaluate the effectiveness of an iPad app, which incorporates evidence-based…

The two most frequently used methods for assessing performance on chained tasks are single opportunity probes (SOPs) and multiple opportunity probes (MOPs). Of the two, SOPs may be easier and less time-consuming but can suppress actual performance. In comparison, MOPs can provide more information but present the risk of participants acquiring…

Introduction: Constant time delay is an evidence-based practice to teach sight word recognition to students with a variety of disabilities. To date, two studies have documented its effectiveness for teaching braille. Methods: Using a multiple-baseline design, we evaluated the effectiveness of constant time delay to teach highly motivating words to…

The acquisition of receptive and expressive language skills by students with autism and developmental disabilities (DD) is often delayed, thus making the process of communicating with others challenging. Some students develop language skills incidentally through conversations with their families and peers, but others require instruction in…

This study investigated the effectiveness of video self-modeling (VSM) for eliminating the public undressing of two elementary-aged students with developmental disabilities during urination. A multiple-probe design across participants revealed that the degree of exposed body parts decreased immediately after introduction of VSM. However, exposure…

Background: This investigation details procedures used to teach enhanced natural gestures (ENGs) and illustrates its use with three students with Angelman syndrome (AS). Materials and Methods: Themes were extracted, using a process of content analysis, to organize individuals' feedback pertaining to previous versions of the instructional…

Communicative and social capacities are known to be of primary developmental importance to all children and often present a particular difficulty for children with neurodevelopmental disorders. A recurring challenge for teachers is achieving effective communication with children who span developmental diversity (e.g. inclusive settings or those…

Research Findings: This study examined preschool teachers' literal talk (LT) and inferential talk (IT) during shared book readings in early childhood education (ECE) and early childhood special education (ECSE) classrooms. We aimed to characterize and compare teachers' LT and IT in these 2 classroom contexts and determine whether differences in LT…

The goal of prompting a child is to prevent him or her from making errors while learning a new skill, and to decrease the amount of time it takes to learn the new skill. As a child shows improvement in performing the skill, adults can fade the amount of assistance provided until the child reaches his or her level of independence. Several prompting…

Rett syndrome (RTT) is associated with a range of serious neurodevelopmental consequences including severe communicative impairments. Currently, no evidence-based communication interventions exist for the population (Sigafoos et al., 2009). The purpose of the current study was to examine the effectiveness of functional assessment (FA) and…

Japanese students with developmental disabilities often exhibit difficulties in reading, particularly in Kanji (ideogram) reading, and in acquiring the equivalence relations between pictures, written words, and sounds. Previous research suggested that one student with autism could acquire Kanji reading along with equivalence relations through…

Children with developmental disabilities are trained using different teaching arrangements. One of these arrangements is called small-group teaching. It has been ascertained that a small-group teaching arrangement is more effective than a one-to-one teaching arrangement. In that sense, teaching academic skills to pre-school children in small-group…

A primary goal of instruction for students with developmental disabilities is to enhance their future quality of life by promoting skill acquisition, which will enable them to live, function, and participate in the community. One instructional method that can help students with developmental disabilities improve independence in performing daily…

Fetal alcohol spectrum disorder (FASD) is a prevalent neurodevelopmental disability with significant implications for learning and behaviour. International research suggests that the prevalence of FASD in school-aged children is 2.3-6.3%. In this paper, we address the questions: (1) what is FASD; (2) what is the prevalence of FASD in schools; (3)…
