This curriculum guide was developed for second-year courses in vocational agriculture in Oklahoma. The curriculum contains 5 sections organized in 16 instructional units. The units follow a standard format established in 1970 for development of instructional materials for all Oklahoma vocational teachers. This format includes eight basic components that form a unit of instruction: performance objectives, suggested activities for the teacher, information sheets, assignment sheets, job sheets, transparency masters and supplements, tests, and answers to tests and assignment sheets. (Depending on the specific objectives, there may or may not be transparency masters, supplements, student supplements, assignment sheets, or job sheets included in the unit of instruction.) All of the unit components focus on measurable and observable learning outcomes. The units in this curriculum cover the following topics: (1) leadership--write, deliver, and evaluate a speech; (2) finance--handle finances, obtain and use credit; (3) plant and soil science--analyze the crop industry, select soil-conservation practices, evaluate plant growth and reproduction, select seed and prepare seedbed, control crop pests and diseases; (4) animal science--interpret nutritional information, maintain animal health, control livestock diseases and parasites; and (5) agriculture mechanics--use power tools, perform position shielded metal-arc welding, perform oxyacetylene welding and brazing, plan project construction, maintain farm plumbing.
