	Module 7: DTT and Naturalistic Teaching Discrete Trial Teaching (DTT) Discrete trial teaching (DTT) involves dividing a skill into small components and teaching each component. Each component is taught using highly-structured procedures involving shaping, prompting, prompt-fading, and immediately reinforcing correct responses (Prelock, Paul, & Allen, 2011). Back to the ABC model, a discrete trial consists of an antecedent (such as the teacher saying “Do this” and putting a block on a stack), the behavior (the student putting a block on the stack), and the consequence (the teacher saying, “Great job stacking blocks!” and giving a reinforcer). These compose one discrete trial. Here is an intro video on the discrete trial from Behavior Frontiers. According to the Texas Guide for Effective Teaching, benefits of DTT for students with autism include: Skills are broken down into short and simple tasks, Motivation is increased through the use of reinforcement, and Tasks presented are generally consistent and clear. You can view the Texas Guide for Effective Teaching Section about DTT including a summary and examples here: http://www.txautism.net/uploads/target/DTT.pdf.
