ABSTRACTThe general purpose of the occupational analysis is

to provide workable, basic information dealing with the many andvaried duties performed in the residential electricity occupation. Itdoes not cover the complete work of a master electrician, only thebasic skills needed to do residential wiring. The document opens witha brief introduction followed by a job description. The bulk of thedocument is presented in table form. Seven duties are broken downinto a number of tasks.and for each task a two-page table ispresented, showing on the first page: tools, equipment, materials,objects acted upon; performance knowledge (related also to decisions,cues and errors); safety--hazard; and on the second page: science;math--number systems; and communications (performance modes,examples, and skills and concepts). The duties include: laying outresidential wiring; installing proper entrance service, primary andsecondary cable runs, electric heat, miscellaneous wiring, and allfinishing electrical devices; and maintaining existing wiring.Appended are lists of mathematics terms and concepts and tools in astandard tool pouch.

FOREWORD

The occupational analysis project was conducted by The Instructional MaterialsLaboratory, Trade and Industrial Education, The Ohio State University in con-junction with the State Department of EdUcation, Division of Vocational Educa-tion pursuant to a grant from the U.S. Office of Education.

The Occupational Analysis project was proposed and conducted to train voca-tional educators in the. techniques of making a comprehensive occupational

analysis. Instructors were selected from Agriculture, Business, Distributive,Home Economics and Trade and Industrial Education to gain experience indeveloping analysis documents for sixty-one different occupations. Represen-

tatives from Business, Industry, Medicine, and Education were involved withthe vocational instructors in conducting the analysis process.

The project was conducted in three phases. Phase one involved the planning

and development of the project strategies. The analysis process was based

on sound principles of learning and behavior. Phase two was the identifica-

tion, selection and orientation of all participants. The training and work-

shop sessions constituted the third phase. Two-week workshops were held

during which teams of vocational instructors conducted an analysis of theoccupations in which they had employment experience. The instructors were

assisted by both occupational consultants and subject matter spe'ialists.

The project resulted in producing one hundred two trained vocational instruc-tors capable of conducting and assisting in a comprehensive analysis of

various occupations. Occupational analysis data were generated for sixty-one

occupations. The analysis included a statement of the various tasks performed

in each occupation. For each task the following items were identified:

tools and equipment; procedural knowledge; safory knowledge; concepts and

skills of mathematics, science and communication needed for successful per-

formance in the occupation. The analysis data provided a basis for generatinginstructional materials, course outlines, student performance objectives,

criterion measures as well as identifying specific supporting skills and

knowledge in the academic subject areas.

PREFACE

The purpose of the following analysis is to identify the skills and knowledgeneeded to perform the duties and tasks required of a Residential Electrician.It does not cover the complete work of a Master Electrician, only the basicskills needed to do residential wiring.

ACKNOWLEDGMENT

We wish to acknowledge the valuable assistance rendered by the followingsubject matter specialists. They provided input to the vocational instruc-

tors in identifying related skills and concepts of each respective subjectmatter area and served as training assistants in the analysis process duringthe two-week workshops.
