For a pilot evaluation of Iowa's regional educational media centers, the 16 centers were organized into four groups according to total public and non-public school enrollment size, and one area was selected at random from each group. Within each group, participants included all county superintendents, all district superintendents, 15 percent of the K-6 public and non-public teachers and principals, and 15 percent of the secondary public and non-public teachers and principals. Data from questionnaires which were completed by participants showed that the majority of teachers sampled in the four areas were using the materials provided in the media centers to some degree, but that more effective communications should exist among center personnel, teachers, and administrators to increase utilization of materials.
