Using Flashcards and Descriptive Feedback to Teach Industrial Kitchen Equipment to a Student with Intellectual Disabilities in a Postsecondary Education Program.

With postsecondary education opportunities for adult students with intellectual and developmental disabilities (IDD) on the rise, it is important to find socially validated research-based methods that are appropriate for the university or other community-based postsecondary instructional settings. The present research examines the effects of using flashcards with descriptive feedback and opportunities to respond, to teach one student with intellectual disabilities, enrolled in a postsecondary education-training program, commonly used industrial kitchen equipment. Results showed that discrete trail instruction, which included an error correction strategy of descriptive feedback plus opportunities to correctly respond was highly effective in mastery and maintenance of kitchen equipment identification, and generalization when asked to locate those items in the university kitchen lab.

Appraisal of comparative single-case experimental designs for instructional interventions with non-reversible target behaviors: Introducing the CSCEDARS ("Cedars").

Evidence-based practice as a process requires the appraisal of research as a critical step. In the field of developmental disabilities, single-case experimental designs (SCEDs) figure prominently as a means for evaluating the effectiveness of non-reversible instructional interventions. Comparative SCEDs contrast two or more instructional interventions to document their relative effectiveness and efficiency. As such, these designs have great potential to inform evidence-based decision-making. To harness this potential, however, interventionists and authors of systematic reviews need tools to appraise the evidence generated by these designs. Our literature review revealed that existing tools do not adequately address the specific methodological considerations of comparative SCEDs that aim to compare instructional interventions of non-reversible target behaviors. The purpose of this paper is to introduce the Comparative Single-Case Experimental Design Rating System (CSCEDARS, "cedars") as a tool for appraising the internal validity of comparative SCEDs of two or more non-reversible instructional interventions. Pertinent literature will be reviewed to establish the need for this tool and to underpin the rationales for individual rating items. Initial reliability information will be provided as well. Finally, directions for instrument validation will be proposed.

Functional analysis of maladaptive behaviors: Rule as a transitive conditioned motivating operation.

The purpose of this study was to examine the role of a staff-delivered rule on the occurrence of challenging behavior (stereotypic touching) of an adult with severe intellectual disabilities. Four experimental functional analysis conditions were developed: (a) attention, (b) rule+attention, (c) rule only, and (d) control. Results showed that the percentage of intervals in which stereotypic touching responses (STR) occurred was greater within the experimental condition where a rule statement was embedded with contingent attention. Results are discussed in light of the plasticity of functional analysis technology to allow for stimulus variation within the typical social attention condition, and the suggestion that the rule statement, in this study, may function as a Transitive Conditioned Establishing Operation (CEO-T), asserting that the provision of attention is more valued in the presence of the stated rule.
