Using Discrete Trial Training (DTT) to Teach Academic and Social Skills
Discrete Trial Training (DTT) is a structured and systematic teaching approach rooted in the principles of Applied Behavior Analysis (ABA). DTT is particularly effective for teaching new skills to students with autism spectrum disorder (ASD) in an educational setting. Here's how DTT can be implemented in the classroom:
Breaking Down Skills: DTT involves breaking down complex skills into smaller, manageable steps or "discrete trials." This allows students to learn and master each component before moving on to the next step.
Clear Instructions: Each discrete trial begins with a clear discriminative stimulus or instruction (e.g., "Touch your nose," "What color is this?"). This ensures the student understands what is being asked of them.
Prompting and Fading: Instructors provide prompts (verbal, gestural, or physical) to assist the student in responding correctly initially. As the student demonstrates mastery, these prompts are gradually faded to promote independent responding.
Reinforcement: Positive reinforcement, such as praise, tokens, or access to preferred activities, is provided immediately after the student responds correctly. This increases the likelihood that the desired behavior will continue.
Data Collection: Detailed data is collected on the student's performance, including correct responses, prompts used, and any errors. This data guides instructional decisions and monitors progress.
DTT can be utilized to teach a wide range of skills, including academic concepts (e.g., literacy, numeracy), language and communication, social skills, and adaptive living skills. By breaking down these skills into discrete trials and systematically reinforcing correct responses, students with ASD can acquire new knowledge and abilities in a structured and supportive environment.
