Training Teachers to Use Environmental Arrangement and Milieu Teaching with Nonvocal Preschool Children

This study investigated the effects of training preschool teachers to use environmental arrangement and milieu teaching in interactions with children using augmented communication systems. Three teachers were taught seven environmental strategies and four milieu teaching procedures through written materials, lecture, modeling, roleplaying, and feedback. All three teachers learned the procedures and generalized their use to two generalization settings. The teachers maintained their use of the techniques across the 3-month maintenance assessment period. The three target children showed increases in total communication and use of targets following implementation of milieu teaching by their teachers.
