Speech and hearing therapists investigated the effectiveness of video taping as a multisensory approach to therapeutic procedures aimed at developing adequate communication skills for students with speech or hearing difficulties. They also studied the usefulness of such taping for parent counseling and inservice training of therapists and teachers. A van was used to provide a mobile classroom, thus allowing several schools to participate in the program. Over three years a total of 2366 students received services from a staff of 12 therapists who developed video tapes to assist in the identification, treatment, and evaluation of speech and hearing problems. Comparison of the results obtained from pre- and post-testing indicated that students receiving therapy utilizing video tapes did not improve significantly more than those receiving the traditional therapy. However, the parents of these students, their classroom teachers, and the speech therapists did profit from introduction of the video taping approach, largely due to the in-service training which was an integral part of the project.
