Task Analysis:
1. Using lots of verbal explanation, demonstrate the entire process to the student.
2. Using the practice phone (which is not hooked up), physically guide the student through the process of responding when the phone rings and then pro, the verbal imitation of the word "hello" after the handset has been guided to the proper position.
3. Continue Step 2, reducing all prompting, until the ring is the only prompt needed.
4. Replace the practice phone wi.th the actual phone by calling that phone from another phone. Continue until the objective is met.
5. Although the objective is met in Step 4, consider adding a role-playing activity that involves phone conversations.
