Discrete trial teaching (DTT) is a common instructional method incorporated into intensive behavioral intervention programs for children diagnosed with autism. Errorless learning strategies are frequently recommended during DTT because they often result in more efficient and effective instruction. The purpose of the present study was to conduct a sequential analysis of the efficacy of three methods for teaching errorless DTT procedures to novice instructors: (a) a self-instruction manual, (b) an instructional video, (c) and brief performance feedback. Three participants mastered DTT following self-instruction and the remaining three participants required all three interventions. The present study extends the literature on training DTT skills by (a) illustrating an efficient, sequential method of staff training, (b) introducing an improved self-instruction manual, and (c) clearly delineating guidelines for implementing an errorless prompt fading strategy during DTT.
离散式单元教学（DTT）是一种常见的教学方法，被纳入针对自闭症谱系障碍儿童的强化行为干预计划中。在离散式单元教学中，常推荐使用无错误学习策略，因为它们往往能带来更高效的教学效果。本研究的目的是对三种向新手教师教授无错误离散式单元教学程序的方法的效果进行序列分析：（a）一本自我指导手册，（b）一段教学视频，（c）以及简短的表现反馈。三名参与者通过自我指导掌握了离散式单元教学，其余三名参与者则需要所有三种干预措施。本研究通过以下方式扩展了关于离散式单元教学技能培训的文献：（a）阐述一种高效的、循序渐进的员工培训方法，（b）引入一本改进的自我指导手册，（c）明确界定在离散式单元教学中实施无错误提示消退策略的指导方针。
