Mastery Training: Effect on Skill Retention

Abstract

SECURITY CLASSIFICATION OF THIS PAGE(Whlt Da&# afolrteQ)/f4ve weeks after training.Each step of the task performance was scored YGo" or 1 -N0 GO."Wheu a crewman performed a step incorrectly, the scorer would correct the step before permitting the crewman to continue.The results indicate a cignificant effect of both amount of training and length of retention interval on recall of the task, but no interaction between the variables.Crewmen perform better on the retention test after the shorter retention interval or after more Antensive training.Differences in performance among the groups are mostly caused by differences on the first retention trial.T. ere is no correlation between ability to perform or retain the task and meotal category.The reason fpr this result may be the lack of variance among crewmen's mental categories.Although the mastery training provided aided retention of the task, only 15% of the mastery trained crewmen were able to perform the task correctly on the first retention trial.The results indicate that mastery training is not efficient for all tasks.Mastery training as compared to refresher training, however, may be useful for tasks that have few steps, must be recalled from memory, must be performed correctly on the first attempt, or for which there are inadequate resources for refresher training..
