The paper discusses the interdisciplinary approach used by the Amity High School House Construction Project to develop a construction cluster in a small high school, to give students on-the-job training, and to teach them the relevancy of academic education. The project's monthly plan of action is briefly described. Suggested activities, competencies, and performance indicators are provided for teaching grade school and high school mathematics, industrial arts, communications, art, physics/chemistry, physical education, business, advanced agriculture, drafting, home economics, occupational versatility, and a construction cluster (e.g., carpentry, cabinetmaking, plumbing, heating, roofing). Competencies involve such subjects as measurements, vocabulary, written and verbal orders, job applications, costs of buying and maintaining a home, heating and cooling systems, stress and strain, selection of color schemes, lifting techniques, safety methods and procedures, blueprints, preparation of specifications, landscapes, excavation, evaluation of dwellings, building codes, advertisements, marketing procedures, and principles and elements of design and housing. The paper concludes with 23 suggested activities on such topics as career interests; homemaking; choosing and preparing for an occupation; apprenticeship; and various types of occupations (e.g., professional, semiprofessional, administrative, office, selling protective service, fishery and forestry, graphic, skilled, semi-skilled, and unskilled).
