Principles of Technology was designed as a high school course in applied science for vocational students in the 11th and 12th grades in Leander, Texas. It consists of a 2-year curriculum covering 14 units in applied physics: (1) force; (2) work; (3) rate; (4) resistance; (5) energy; (6) power; (7) force transformers; (8) momentum; (9) waves and vibrations; (10) energy convertors; (11) transducers; (12) radiation; (13) optical systems; and (14) time constants. The curriculum was designed to increase the employability of vocational students, emphasize principles of technology, increase the appeal of instruction, and meet the requirements for high school graduation in science. The bulk of the document consists of three appendices: (1) principles of technology--essential elements and competencies; (2) list of equipment and supplies for principles of technology by unit; and (3) advisory committee members and minutes of committee meetings.
