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
