The field testing project evaluated a guide to help 4th, 5th, and 6th grade teachers introduce students to musical concepts through a series of ten 30-minute television programs (see ED 143 596). The formative evaluation focused on the appropriateness of program materials for the intermediate grades, the ability of the curriculum to affect learner outcomes, and curriculum flexibility. Formal pilot testing took place in the public schools of Ann Arbor, Michigan, and Washington, D.C. Units and activities dealing with rhythm and form were preselected by researchers and time limits were imposed on teachers. The procedure involved giving a 10-minute test to students before and after exposure to the videotape lessons. Project administrators and on-site research assistants cooperated in pre- and posttesting and follow-up activities. Findings indicated that the level of difficulty of the curriculum materials seemed highly appropriate for the intermediate grades. Children were moderately successful to successful in understanding and distinguishing various forms and rhythms. The materials lent themselves to diverse uses. As a result of this study, the following activities are recommended: teacher training workshops, an audience awareness survey, and a summative evaluation. Included in the appendix are pre- and posttests, teacher feedback forms, and transcripts of interviews with teachers who participated in the field test. (Author/DB)
