Discrete-trial teaching (DTT) breaks a skill into short, repeatable trials, each with a clear beginning and end.
Example
The RBT holds up a picture and says “What is this?” (instruction). The learner says “cat” (response). The RBT gives praise and a token (consequence), then a short pause before the next trial.
Key points
- A trial usually has an instruction, a possible prompt, the learner’s response, a consequence and a short pause between trials.
- Data are taken on each trial.
- It is often used for new skills that need many practice opportunities.
Exam tip
Contrast DTT, which is structured and trial-based, with naturalistic teaching, which builds skills inside everyday activities.
Common mistake
Skipping a clear consequence or delivering it late. Each trial has an antecedent, response, and consequence in quick sequence.
Quick check
What are the parts of a discrete trial? Instruction, response, consequence, then a brief pause before the next trial.
