Lesson VOC 44
Task: Shampoo others' hair.
Prerequisites: ADT 64, ADT 73, VOC 5
Concept: Although the regulation of water temperature (see prerequisite ADT 64) is actually also a prerequisite of washing and rinsing own hair (ADT 73, also a prerequisite), this skill should be reviewed independently because it is a very critical component if washing someone else's hair is a task in a work setting. Different work environments will have different processes for accomplishing this activity; therefore, efforts should be made to learn the specific processes involved with a potential employer, and responsiveness to supervisory direction (see prerequisite VOC 5) should be reviewed.
Behavioral Objective: When requested to "please wash (the name of a customer's) hair," the student will wash and rinse the indicated person's hair in a manner suitable to both the "customer" and "supervisor" to a 90% accuracy level for 20 trials.
Materials: A sink suitable for washing hair, shampoo ("no tears" type preferred), and towels.
Task Analysis:
1. Review with the student the process involved in washing his or her own hair, giving close attention to the student's ability to safely regulate water temperature.
2. While you wash the student's hair, demonstrate the process and activities involved to the student. Use lots of verbal descriptions during this process.
3. Using another instructor or student to act as the customer, physically guide the student in the entire process of washing and rinsing the customer's hair, ending by wrapping the hair in a towel.
4. Continue Step 3, reducing physical guidance until only step-by-step verbal cues are needed.
5. Continue Step 4, substituting a real customer (if reasonable) and reducing prompting to a total-task verbal request. Maintain supervision at all times.
