(Part of the PRO-ED Series on Autism Spectrum Disorders–Second Edition)
Discrete trial training (DTT) is a method of teaching individuals with autism spectrum disorder (ASD) based on applied behavior analysis (ABA). Skills are broken into discrete steps and then taught in massed trials. With DTT, steps are taught one at a time, instead of teaching an entire skill all at once. Concepts covered include errorless learning, methods of reinforcement, and how to use behavior momentum. The text explains how to collect, interpret, and use data to make teaching decisions. Finally, the text details a method for evaluating implementation of DTT.
Examples and practice exercises are also provided throughout the book to help readers gain guided practice and a firm understanding of the concepts and skills that form the foundation for DTT.
