Application of ARI Skill Retention Model to Wheel Vehicle Maintenance Tasks.

摘要

The Skill Retention Model is a model that describes how people forget technical tasks in terms of such task characteristics as the number of steps in the task and the quantity of the job aids. We administered the Skill Retention Model to seven expert wheeled vehicle mechanical/instructors (SMEs) at the Ordnance Center School, Aberdeen, MD. A total of nine tasks were covered, five tasks in five hours on each of two days, with one task being evaluated on both days and one evaluator serving on both days. We identified three out of nine tasks that are rapidly forgotten. Out of ten task characteristics, five differentiated the three tasks easily forgotten from those that are not easily forgotten. We recommended ways to improve training and calculated how much retention would increase with improved training.
