This study examined the efficacy of an electronic essay-writing strategy to improve the expository writing skills of 20 young adults with intellectual and developmental disabilities enrolled in a program at an institute of higher education in the midwest. A pretest and posttest experimental design with random assignment to treatment or control…

Few published studies have systematically compared the efficacy of different prompt-fading methods in the training of complex response chains. The current study systematically compared a most-to-least physical prompt fading hierarchy with a most-to-least vocal prompt fading strategy in the training of four arbitrary Tinkertoy® construction tasks…

Previous research suggests that high quality contact between people from different groups is a relatively consistent way of decreasing stereotypes and prejudices. The authors determined that a very short-term, service-learning project with people with developmental disabilities (DD) could reduce college students' fear of this population. In…

We conducted a systematic literature review of anger management in people with intellectual disabilities (ID). We identified 2 studies that used randomized controlled trials and 6 that used pretest-posttest nonequivalent control group designs. The mean between-group effect size was 1.52 for randomized controlled trials and 0.89 for the other…

Eight six-year old German children with development disabilities regarding such number competencies as have been demonstrated to be among the most relevant precursor skills for the acquisition of elementary mathematics received intensive training with the program "Mengen, zählen, Zahlen" ["quantities, counting, numbers"] (MZZ,…

A phonics-based reading curriculum in which students used an iPad to respond was created for students with developmental disabilities not able to verbally participate in traditional phonics instruction due to their use of augmentative and assistive communication. Time delay and a system of least prompts used in conjunction with text-to-speech…

This paper includes a nontechnical description of methods for calculating effect sizes in intellectual and developmental disability studies. Different hypothetical studies are used to illustrate how null hypothesis significance testing (NHST) and effect size findings can result in quite different outcomes and therefore conflicting results. Whereas…

Aquatic therapy is an intervention for children with Developmental Coordination Disorder (DCD) that has not been investigated formally. This was a pilot randomized controlled trial to investigate the feasibility and preliminary effectiveness of an aquatic therapy program to improve motor skills of children with DCD. Thirteen children (mean age 7…

The purpose of the paper was to examine the effect of participation in a music mentorship program on the self-esteem and attitudes of at-risk students. Participants (N = 24) were adolescent girls enrolled in a special program for secondary students who are at risk for academic failure and who are experiencing conflict in school and at home.…

This study evaluated the impact of a curriculum called the Early Literacy Skills Builder on the language and early literacy skills of students with significant developmental disabilities.
