The seven units are on shop orientation and safety principles, introduction to direct current, circuitry, introduction to alternating current, circuit components, basic power supplies, and semiconductor devices. The first section is designed to teach teachers how to use the materials and includes an explanation of instructional elements, an instructional-task analysis each unit, a seven-page glossary, and a last of 14 references. The instructional elements for the units include objectives, suggested activities, information sheets, transparency masters, assignment sheets, jot sheets, tests, and test answers. Some e.Lements, such as the information sheets, include diagrams and line drawings. (CML) A A * * tR * A A * *st * 7, *A * tt *r * * * x * **1ft st A ItOt * * * * * * 7.

This approach is iesigned to provide a practical and realistic approach to compe- tency-based training mates :315 in electronics and to provide basic electronics competencies for many other vocational programs. Identified are those tasks that are common not only to the entry-level electronic technician but also to other vocational occupational programs such as appliance repair, heating and aircon- ditioning, auto mechanics. etc. Basic Electronics therefore covers the tasks not only :-equired of the electronic technician but also those tasks required in many other occupations. Basic Electronics provides the foundation and serves as a building block for progressing toa higher level of competency in many occupations. General Electronics Technician includes those additional tasks required above Basic Electron- ics for job entry in the electronics field. Upon completion of the Basic Electronics and General Electronics Technician competencies, students are ready for job entry or may continue their education by specializing inone of many electronics areas such as communication electronics. Every effort nas been made to make these publications basic, readable, and by allmeans, usa- ble. Three vital parts of instruction have been intentionally omitted from the publication: moti- vation, personalization. and localization. These areas are left to the individue! instructors and the instructors should capitalize on them. Only then will these publications really becomea vital part of the teaching-learning process.

Each instructionalunit incluies some or all of the basic components of a unit of instruction; performance objectivessuoested activities for teachers and students. information sheets, assignment sheets, jobsheets. visual aids, tests, and answers to the tests. Units are planned formore tnar one lesson or class period of instruction. Careful study of each instructional unit by the teacht:r will helpto determine: A. The amount of material that can be covered in each classperiod B. The skills which must be demonstrated 1. Supplies needed 2. Equipment needed 3. Amount of practice needed 4. Amount of class time needed for demonstrations C. Supplementary materials such as pamphletsor filmstrips that must be ordered 1D. Resource people who must be contacted Objectives Each unit of instruction is based on performance objectives. Theseobjectives state the goals of the course, thus providing a sense of direction andaccomplishment for the student. Performance objectives are stated in two forms: unit objectives,stating the subject matter to be covered in a unit of instruction; and specific objectives, statingthe student performance necessary to reach the unit objective. Since the objectives of the unit provide direction for theteachinglearning process, it is important for the teacher and students to havea common understanding of the intent of the objectives. A limited number of performance terms have been usedin the objectives for this curriculum to assist in promoting the effectiveness of the communicationamong all individ- uals using the materials. Reading of the objectives by the student should be followedby a class discussion to answer any questions concerning performance requirements for each instructional unit. Teachers should feel free to add objectives which will fit the materialto the needs of the stu- dents and c,mmunity. When teachers add objectives, theyshould remember to supply the needed information. assignmen' and/or job sheets, andcriterion tests.
