As a possible solution to the problem of inaccurate perceptions and negative attitudes toward vocational-technical occupations among teachers and pupils, the project investigated the feasibility of training secondary school teachers in a range of disciplines to serve as agents of manpower-economic information dissemination and attitudinal change. Methodology involved in-service seminars and summer institutes for a total of 107 teachers. Regression analysis of the training program data indicated that pupils of the trained teachers experienced greater increases in knowledge and developed more positive attitudes toward nonprofessional work modes than did pupils of teachers not participating in the in-service training. However, analysis did not show that pupils of participant teachers experienced a significantly greater increase in realistic attitudes toward nonprofessional work modes. From these findings, it was concluded that the program objectives had been actualized. Development of a delivery system utilizing multimedia technology, with a software support system, was recommended. A summary of the teacher training units, lists of participants, evaluation variables, and the study instruments are appended. (Author/MF)
