Knowledge/Skill Barriers: Studying Successful Case Examples



This chapter presents three case examples highlighting the successful use of strategies for addressing knowledge/skill barriers. The first case illustrates the use of instructional coaching to tackle the knowledge/skill barriers experienced by a school team who served a five-year-old boy diagnosed with Angelman syndrome and a seizure disorder. The second case shares how the knowledge/skill barriers of preservice and inservice professionals were addressed through online training. The third case illustrates the use of telepractice to attend to the knowledge/skill barriers experienced by the parents of a 28-month-old child diagnosed with autism spectrum disorder (ASD). Although the case studies vary in many ways, there are similarities in that all three (a) recognized the presence of knowledge/skill barriers, (b) identified the knowledge/skill needs of professionals and communication partners, and (c) attended to principles of instructional design when planning, implementing, and evaluating their instruction and support.
