ABSTRACT:
An evaluation of four different dissemination modes distributing activities developed through a teaching materials development program was performed. The activities, developed for use in middle schools, focused on Great Lakes topics in science, history, and social studies. It was found that short intensive workshops were more effective than longer workshops both in participant use of materials and in transmission of the materials to other potential users. The difference in usage seems to be related to differences in the professional orientation of teachers attracted into the two different types of workshops. Simply giving activities to prospective users resulted in no usage. Those individuals who took the trouble to mail order the materials used them but at a somewhat lower frequency than those who participated in a workshop. It is concluded that short intensive workshops are the most cost-effective way of ensuring usage of the type of curriculum materials disseminated in this program.
