Lesson SEN 2
Task: Respond to sound.
Prerequisites: None other than known ability to hear
Concept: Auditory abilities can be assessed even if the student is incapable of signifying a response. If auditory difficulties are suspected, a formal assessment by a trained professional should be conducted. Responses can be measured by movement of the student toward the sound source or a change in affect such as a smile. The important thing to remember is that other types of sensory input, such as sight or tactile awareness, must not be involved in the activity that is measuring response to sound. For example, a pleasant noise can be presented to the student but should be done so that he or she cannot see the teacher or feel the vibration of the sound. Certain illnesses and conditions can cause high-frequency hearing loss; therefore, different sounds with different pitches should be attempted.
Behavioral Objective: When presented with a tone or music, the student will demonstrate a measurable response to a 90% level of occurrence over 20 trials.
Materials: None.
Task Analysis:
1. Begin interaction with the student by using all other known sensory modalities such as physically interacting with the student, showing him or her a favorite toy or object, or playing familiar music. Attempt to elicit any kind of positive response. If a positive response occurs, immediately praise the student in a very active manner for every occurrence.
2. After rapport with the student has been established, attempt to couple a positive response, such as that elicited in Step 1, to your voice and a musical tone.
3. Modify Step 2 to only presenting auditory stimulation. Physically prompt the attending response as needed.
4. Continue Step 3, gradually reducing the prompting needed to elicit the response.
