The Colorado State Department of Education sponsored a project to inform Colorado schools of the use and scope of instructional media and to determine the best method of disseminating this information. Schools selected on the basis of interest, location, budget, and size were a signed to one of three conditions. Plan A, used in 40 schools, was a breadth approach to dissemination, involving a multi-media demonstration, workshops, and team visitations. Plan B, a depth approach used in eight schools, involved an evaluation of audiovisual programs, a 12 week course in media utilization, and a follow-up consultation service. Non-host schools acted as controls. The four measuring instruments were a facilities checklist, an attitude inventory, and two questionnaires. Results are based on data collected during the two year project and analyzed only for schools participating f r the duration of the project. These measures indicated an increase in the number of audiovisual directors, an increased willingness to buy equipment, a liberalization of buying policies, an increase in clerical assistance and in quantities of materials, and a favorable change in teacher opinions. Data also indicated a difference between administrators' and teachers' attitudes. No clear evidence supported one plan over the other, suggesting the need for both. (JO)
