Each volume of this three-volume set is divided into two major sections. The first section presents the narrative report of a study designed to assist Michigan vocational agriculture teachers in implementing local competency-based vocational agriculture programs by (1) developing student performance objectives; (2) identifying up-to-date reference materials for teaching agricultural production, agricultural mechanics, and ornamental horticulture; and (3) developing a delivery system and materials to provide competency-based education training. The second section, which comprises the bulk of the document, contains three appendixes: student performance objectives, selected references for teachers, and a key to finding the sources. This second volume presents the identified objectives and reference materials for teaching agricultural mechanics. The other two volumes contain the objectives and reference materials for teaching agricultural production (CE 016 907) and ornamental horticulture (CE 016 909). (BM)
