A comprehensive evaluation of a train-the-trainers model for training education staff to assemble adaptive switches

Abstract

We evaluated a train-the-trainers program for training education staff to assemble adaptive switch mechanisms. The adaptive switches were designed to assist persons with severe mental and physical handicaps in operating various electrical apparata. In Phase 1, a five-step training program (written and verbal instructions, modeling, performance practice and feedback) was used to train four teachers to assemble an adaptive switch. Also in Phase 1 social validity data were collected which supported the importance of adaptive switches for persons with severe physical impairment, as well as the need to train switch assembly skills to human service personnel. In Phase 2, the four teachers used the same five-step training program to train 22 teacher assistants to assemble an adaptive switch. Acceptability measures indicated that training was well received by the teachers (trainers) and assistants (trainees), and time efficiency measures indicated an average of less than two hours of training time was necessary for every two trainees. Effects of the training program were replicated in Phase 3 with two staff from another school. Results of the program are discussed in regard to using a train-the-trainers model as a means of upgrading staff skills, and helping reduce the gap between educational technology presented in the professional literature and that reflected in routine service settings.
