| This study examines the idea of using prerequisite skill acquisition to predict the success of acquiring requisite skills. The study used a descriptive quantitative ex post facto case study design to examine a convenience sample of 5 students' with autism spectrum disorder acquisition rates of colors, categories, and statement-statement programs. Historical data was collected from discrete trials on data records designed by a California Non-public School/Agency. Data was analyzed within participants using descriptive statistics, comparing the mean rates of acquisition (in days) of prerequisite skills and their requisite counterpart, specifically colors to categories, and categories to statement-statement programs. Further, individual participant data was examined for trends of acquisition using visual analysis and trend lines. Findings indicate that it is possible to predict the acquisition of statement-statement programs based on the acquisition rates of categories for the students in this case study. Further, the findings indicate that future research into the prediction of skills using prerequisite skill would yield positive results, but not necessarily for the programs listed in this study specifically. Predicting future skills will facilitate social change and benefit providers, parents, and school districts by giving them the tools that will meet state and federal guidelines and allow for greater accuracy and validity in determining educational objectives. |
