ABSTRACTThe general purpose of the occupational analysis is

to provide workable, basic information dealing with the many andvaried duties performed in the horticulture' equipment and servicesoccupation. The document opens with a brief introduction followed bya job description. The bulk of the document is presented in tableform. Fourteen duties are broken down into a number of tasks and foreach task a two-page table is presented, showing on the first page:tools, equipment, materials, objects acted upon; performanceknowledge (related also to decisions, cues and errors);safety--hazard; and on the second page: science; math--numbersystems; and communications (performance modes, examples, and skillsand concepts). The duties include: fitting, repairing, and using shoptools and equipment; servicing and maintaining engines, hydraulics,and turf equipment; installing, servicing, and maintaining anelectrical system; maintaining water systems, tree and shrubequipment, artificial environment controls, trucks and forklifts, andtractors and related equipment; maintaining and testing steamgenerators; testing and caring for spraying and spreading equipment;installing, testing and caring for irrigation and sprinkler systems;and carpentry and masonry maintenance and construction.

The occupational analysis project was conducted by The Instructional Materials

Laboratory, 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 in

developing analysis documents for sixty-one different occupations. Represen-

tatives from Business, Industry, Medicine, and Education were involved with

the 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 the

occupations in which they had employment experience. The instructors were

assisted by both occupational consultants and subject matter specialists.

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; safety knowledge; concepts and

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

formance in the occupation. The analysis data provided a basis for generating

instructional materials, course outlines, student performance objectives,

criterion measures as well as identifying specific supporting skills and

knowledge in the academic subject areas.

PREFACE

This task analysis was undertaken with the understanding that it was

complimenting the other eight horticulture areas.

The areas covered should allow instruction in any area of maintenance

of tools or equipment. This can be used to suppliment the instruction

in other areas as needed or to be taught as an individual unit on .

mechanical skills.

The tasks are arranged so units can be pulled on identifying, maintaining,

overhauling, or test operating.

No serious depth was attempted as each teacher will know how much time

he or she wants to spend and to what depth he or she wants to go.

ACKNOWLEDGMENT

We wish to acknowledge the valuable assistance rendered by the following

subject matter specialists. They provided input to the vocational instruc-

tors in identifying related skills and concepts of each respective subject

matter area and served as training assistants in the analysis process during

the two-week workshops.
