Discrete Trial Teaching (DTT)

Prompt

"touch this" is an example assist the learner in responding correctly use when there is a high risk of error

Steps of discrete trial (4 STEPS)

1. Cue prompt (touch ears) 2. Response (from learner) 3. Consequence (depends on response) 4. Intertribal intervention (RBT records data)

Where can DTT be done?

Anywhere ABA happens 1:1 ratio (1 RBT: 1 learner) Distraction free Highly structured

Steps of DTT

Cue, prompt, response, consequence, and interval interval (collecting data)

Skills taught during DTT?

Imitation Receptive language Expressive language Conversations Sentences & grammar New behavior

Disadvantages of DTT

Lack of generalization to natural environment Robotic responding Labor, time, and cost intensive

Advantages of DTT

Multiple learning opportunities Individual instruction Strutted for success Research based

Discrete Trial Teaching

Teaching is simplified and structured steps Skills are broken down into the smallest components and then built up using DTT to teach one step at a time Ex: instead of coloring at once, teach read first, then blue, then green, etc

Intertrial Interval

brief pause (2-5 seconds) after the consequence, record data, and reset for the next trial

Consequence

happens IMMEDIATELY after the response never delay consequence

Response

how the learner answers the SD (or cue)

Cue

presenting a clear instruction to the learner
