The primary purpose of this study was to examine the effectiveness of video modeling delivered on an iPod to increase percentage of accuracy of task completion. A single subject combination design replicated across four elementary school participants diagnosed with autism was used to evaluate the percentage of steps completed accurately. Videos were created in subjective view, as if participants were performing the task, and downloaded to an iPod Nano. Multiple opportunity initial probe trials will be conducted to establish the percentage of accuracy participants performed the target behavior. During instruction videos were presented the entire task to participants and post video modeling probe trials were conducted to assess percentage of accuracy after instruction. Additional efficiency data were collected on number of sessions and errors to criterion. Data on types of errors, duration, latency, and topographical errors were also collected.
