Using a Person-Centered Approach in Community-Based Instruction for Adults with Developmental Disabilities

Instruction is a variable that has enhanced community access for adults with developmental disabilities. Community-based instruction emerged as an especially useful format to teach individuals daily living and work skills in the settings where skills would be used. As advocacy and self-advocacy for individuals with developmental disabilities increased, professionals recognized the importance of empowerment and self-determination in gaining community access. Adult education that incorporates the values of person-centered planning will evolve beyond what has traditionally been viewed as community-based instruction. This article describes the characteristics of community-based instruction designed to enhance not only community access, but also the participant's overall quality of life.     

The Use of a Personal Trainer to Enhance Participation of Older Adults with Severe Disabilities in a Community Water Exercise Class

Inclusive instruction was provided for three older adults with profound mental retardation in a water exercise class at a local YMCA. The older adults were taught to exercise through the use of systematic prompting. A multiple baseline design across participants with an embedded reversal was used to evaluate the impact of a personal trainer. The three participants performed the exercise, but regressed without the assistance of the trainer, as demonstrated by the reversal. Data collected during peer prompting and maintenance conditions indicated that the participants continued to exercise at levels higher than baseline but lower than with a personal trainer.     

Increasing the efficiency of instruction for a person with severe disabilities: The applicability of Fitts' law in predicting response time

The purpose of this study was to demonstrate the applicability of Fitts' law in predicting the response duration of instruction-specific head movements for a person with severe multiple disabilities. Fitts' law is a motoric algorithm that calculates an index of difficulty (ID) for responses in relation to the variables of stimulus width and stimulus amplitude. Four functional tasks from the learner's current continuing education plans were targeted: photocopying, using a paint well, model painting, and communication symbol sequencing. For each of the four tasks, two sets of indices were calculated by (1) holding constant stimulus width while varying amplitude, and (2) holding constant stimulus amplitude while varying width. Results showed that response duration varied as a function of ID variation.     

Assessing choice-making and preference in adults with profound mental retardation across community and center-based settings

We examined choice and preference in four adults with profound mental retardation within the context of a community-based and center-based location. Prior to the preference analysis, an independent selecting response was empirically assessed and validated for each adult. Results of the preference analysis showed that in the community site there was a higher cumulative frequency of choice-making responses towards beverages for all participants, and an indication of beverage preference for two of the four participants. Conversely, in the center-based setting, there were fewer responses made towards the beverages, and no indication of preference for any of the four adults. These results remained consistent during maintenance checks at 2, 4, 6, and 8 weeks post-intervention.     

The Role of Response Effort and Motion Study in Functionally Equivalent Task Designs and Alternatives

We evaluated the effects of functionally equivalent task designs and alternatives, as validated by motion study procedures, on dependent variables (nonadaptive responses, use of alternative, attempts at task, and completed attempts at task) relevant to performing a selected task. First, we evaluated the effects of functionally equivalent task designs on the dependent variables. Second, we evaluated the effects of an efficient functionally equivalent alternative on the variables. Third, we compared the effects of the efficient functionally equivalent alternative with a less efficient functionally equivalent alternative on the same variables. The results showed that the inefficient functionally equivalent task design occasioned higher rates of nonadaptive responses than the efficient functionally equivalent task design. The results also showed that the functionally equivalent task designs and alternatives competed within and across response classes to reduce nonadaptive responses. Mixed results were obtained in comparing the effects of the efficient versus the less efficient functionally equivalent alternatives. We provide evidence for extending the current concept of functional equivalence to include task design responses as well as alternative responses in functional equivalence training.     

Guidelines for flash card instruction

Flash card drills provide students with a means to memorize information such as sight words, math facts, state capitols, foreign language vocabulary, and equations. Because of the utility of flash cards in educational practice, information on behavioral strategies to increase the effectiveness of their use may be especially valuable to teachers. This article provides guidelines for flash card instruction based on current research. These guidelines are to: a) intersperse known items, b) minimize errors, c) use feedback for correct and error responses, and d) select an instructional arrangement (e.g., group format) that will enhance responding. Future research may refine these guidelines to improve teaching effectiveness.     

Functional reading for students with developmental disabilities who are linguistically diverse

Students with moderate and severe disabilities often have language deficits that make the acquisition of reading challenging. Sight word instruction of daily living skills is one method of intervention that benefits students with severe disabilities who have not achieved literacy. When students with developmental disabilities are also linguistically diverse, acquisition of reading skills becomes more complex. Sight words must be chosen that are relevant to the students own community. A critical decision in planning sight word instruction is whether to provide instruction in the student's primary language or in English. These issues are discussed and an illustration is given of the heterogeneity among students with developmental disabilities who are linguistically diverse.
