Describe the basic components of Discrete Trial Teaching (DTT).

• A. A chain of environmental prompts with no reinforcement.
• B. An antecedent (SD), a clearly defined prompt if needed, a response, and a consequence with reinforcement.
• C. A motivational operation, a response, and punishment.
• D. Natural environment teaching without prompts.

Answer: (B)

Discrete Trial Teaching uses a trial-based, structured sequence. Each trial begins with an antecedent or discriminative stimulus that signals what behavior is expected. If the learner needs help, a clearly defined prompt is provided to guide the correct response. After the learner responds, a consequence is delivered—typically reinforcement for a correct response—to increase the likelihood of that behavior occurring again. This sequence is repeated in rapid, discrete trials to build fluency and make progress easily trackable through data. The described sequence—SD, prompt if needed, response, and reinforcement—captures the core structure of DTT. The other options describe approaches that omit reinforcement, rely on punishment, or use naturalistic, prompt-free teaching, which are not aligned with the standard DTT framework.
