The purpose of this study was to (1) select six vocational areas for Career Exploration Work Simulation Units development, hereafter referred to as CEWSU (2) design mock-up sites for CEWSU construction, (3) specify materials to be used in the mock-up, (4) describe tasks to be completed in the simulation exercises, (5) construct six CEWSU simulation units for placement in junior high school career education programs, (6) gather materials and tools to be used in each of the six CEWSU, (7) develop and program cassette tape instructions and flip charts for the CEWSU, (8) field test the CEWSU, (9) revise the CEWSU according to field test results, (10) publish replicable plans for the construction and operation of each CEWSU. The ultimate goal of this project was to design and develop a product for u s e in the public school system. For the final product to be considered effective it had to meet various criteria. The criteria were as follows: The CEWSU had to be self-instructional. The CEWSU had to provide a hands-on experience. The CEWSU had to provide the experience in a short period of time. The CEWSU had to be inexpensive to operate. The CEWSU had to be readily available to youth. The CEWSU had to simulate an actual work experience. The implications from the results indicated that: Not all of the criteria listed above were met by all of the CEWSU. The CEWSU developed in the present study should be reprogrammed for use with the developmentally disabled child. Many more CEWSU, for career exploration, should be designed and developed in other vocational areas than those covered in the present project.
