This guide contains instructor's materials for a nine-unit secondary school course on fundamentals of electronics. The units are conductors, insulators, semiconductors, and atomic structure; basic concepts and sources of electrical quantities; Ohm's Law; units and conversions; use of multimeters; circuits; electromagnetics and electrostatics; alternating current signals and measurements; and reactive and resonant circuits. The document begins with advice on its use and a cross-referenced table of instructional materials that show which materials in the guide (transparency masters, handouts, assignment sheets, and test items) are directed at which competencies and instructional objectives. Each unit contains the unit objective, student objectives, a list of references, notes to the instructor, lesson plans, a unit test, and answers to the unit test. The lesson plans may include a glossary, information sheets, transparency masters, job sheets, assignment sheets, and test items. (CML)
