This study examined the potential of self-teaching centers in 12 selected county offices of the South Dakota Cooperative Extension Service. The self-teaching centers used either 35 mm slide-tape or ½ inch videocassette projection systems as the key teaching instrument. The study measured the time involved in maintaining and using centers and determined any significant variation in a center’s use due to county population and local Extension office differences. The study reviewed when and why the centers were used, and which topics were most often selected. Where viewers had a choice between projection systems, their performances were recorded. Users were asked (in a questionnaire) if they felt the programs were acceptably presented. The South Dakota Cooperative Extension Service will use the information in determining if self-teaching centers should be incorporated into county audiovisual systems. The information may also be useful to Extension Services in other states that are considering alternative ways to deliver information to their various publics.
