MODULE: Discrete Trial Training (DTT)

Overview

Discrete trial training (DTT) is a method of teaching in which the adult uses adult-directed, massed trial instruction, reinforcers chosen for their strength, and clear contingencies and repetition to teach new skills. DTT is a particularly strong method for developing a new response to a stimulus. Its limitations involve lack of reinforcement of learner spontaneity and difficulty with generalization. Thus, once a skill is learned in the DTT format, it is important to develop plans for teaching generalized use of the new skill across environments, materials, and people, and also to develop teaching plans for learner initiation of the new skill.
