discrete trial training
A structured behavioral teaching method that breaks skills into small components taught through repeated practice trials with clear instructions and immediate feedback.
Full Definition
Discrete Trial Training (DTT) is a systematic instructional approach that involves breaking down complex skills into smaller, teachable components that are presented in a structured, repetitive format. Each trial consists of a clear instruction or discriminative stimulus, a child response, and an immediate consequence (reinforcement or correction). DTT sessions typically involve multiple trials of the same or related skills, with careful attention to prompt fading, error correction, and data collection. This approach is characterized by adult-directed instruction, controlled learning environments, and systematic progression through skill hierarchies. DTT has extensive empirical support, particularly for teaching academic, communication, and adaptive skills to children with autism spectrum disorders and developmental disabilities.
Usage
Usage note: Often abbreviated as DTT; emphasize the structured, trial-by-trial format to distinguish from naturalistic approaches.
