Discrete Trial Training (DTT)
Discrete trial training (DTT) is a one-to-one instructional approach (most typically) used to teach skills in a planned, controlled, and systematic manner. DTT is characterized by repeated, or massed, trials that have a definite beginning and end. Within DTT, the use of antecedents and consequences is carefully planned and implemented. The instructional trial begins when the practitioner presents a clear direction or stimulus, which elicits a target behavior. Positive praise and/or tangible rewards are used to reinforce desired skills or behaviors. Data is typically collected on every trial. Other practices that are used in DTT include task analysis, prompting, time delay, and reinforcement.
离散式训练（DTT）是一种一对一的教学方法，通常用于以计划、受控和系统的方式教授技能。DTT的特点是反复或集中进行的训练，这些训练具有明确定义的开始和结束。在DTT中，先行条件和后果的使用经过仔细计划和实施。教学试验在从业者提供明确的指示或刺激时开始，这激发了目标行为。积极的表扬和/或有形的奖励用于强化期望的技能或行为。通常会在每次试验中收集数据。DTT中使用的其他实践包括任务分析、提示、时间延迟和强化。
