Generalized use of a handheld prompting system

Area of Science:

• Special Education
• Assistive Technology
• Applied Behavior Analysis

Background:

• Adolescents with moderate intellectual disabilities often face challenges in acquiring and maintaining vocational skills.
• Generalization and long-term maintenance of learned skills are critical for successful vocational outcomes.

Purpose of the Study:

• To evaluate the effectiveness of a handheld computer prompting system.
• To assess the system's ability to facilitate skill generalization and long-term maintenance in vocational tasks.
• To determine the impact on adolescents with moderate intellectual disabilities.

Main Methods:

• A commercially produced handheld computer was utilized as a prompting system.
• Four adolescent students with moderate intellectual disabilities participated in the study.
• The system was used to teach a task, followed by generalization to more complex tasks.

Main Results:

• All four students successfully learned to use the handheld computer prompting system.
• Students generalized the use of the system to perform more complex vocational tasks.
• Task performance was maintained at 100% for up to 9 weeks.

Conclusions:

• Handheld computer prompting systems are effective for teaching vocational skills to adolescents with moderate intellectual disabilities.
• The technology facilitates skill generalization and ensures long-term maintenance of vocational abilities.
• This approach offers a promising avenue for enhancing vocational independence in this population.
