This document consists of vocational education teaching aids that originated in a special needs summer workshop at Arizona State Industrial School; the units are aimed at the potential dropout/special needs type of student (rather than the handicapped) who because of cultural, psychological, or aptitudinal reasons is not able to operate on a regular program. Consequently, each unit is defined further into sub-units, and precision-type teaching is used to check students step-by-step on the carrying out of objectives and activities. For instance a veterinarian's helper unit is broken down further into areas of aiding veterinarian with treatment, grooming animals, nursing animals, cleaning reception room, helping clients, and feeding animals. Other units included are shoe repairing, lapidary, florist, silversmithing, nursery worker, gardening, cotton farm laborer, cabinet-countertop production worker, and concrete finisher's helper. (EA)
