Lesson S&L 2
Task: Imitate vocalizations (sounds).
Prerequisites: ADT 1, COG 11, SEN 2, S&L 1
Concept: This activity marks a beginning of expressive (spoken) language. The objective is to begin the imitative process, not necessarily the imitation of actual words or useful sounds. This sample lesson attempts to take the prerequisite skill of vocalizations (S&L 1) and modify or shape the vocalizations made into an imitation process.
Behavioral Objective: When the instructor presents the student with a vocal sound of one syllable, the student will repeat that sound (or a similar sound) to a 90% accuracy level for 20 trials.
Materials: Objects or activities known to be enjoyed by the student.
Task Analysis:
1. Interact with the student using the objects or activities known to provide enjoyment to the student. As vocalizations occur, immediately repeat the sounds made by the student. Maintain eye contact, where possible, in this process.
2. Continue Step 1 and gradually delay the imitation you make from an immediate response up to a 3-second period.
3. Attempt to set up a pattern where multiple examples of vocal imitations are occurring until it is unclear whether the student or you is initiating the imitation sequence.
4. Begin actual imitation activities where you present a sound similar to those used in Step 3. Use lots of verbal praise for any effort, even if any sound (not necessarily the sound presented) is attempted.
5. Continue Step 4, offering verbal praise only when the sound made by the student approximates the sound presented. Use only one-syllable examples and continue until the objective is met.
