Field testing and evaluation of Project HEAR (Human Educational Awareness Resource) are reported in this document. The program described consists of Primary, Intermediate, and Secondary Learning Units (resource curriculum materials) which are non-sexist, ungraded, skill-building, student-centered, sequentially organized, and experiential. The stated purpose of the project is both to present students with meaningful and realistic exploration of the world of work and to remove myths and stereotypes from career choice. Curriculum materials were field tested over 3 years in 13 New Jersey school districts with approximately 3,000 students using the program. The project was validated in 1975 by a U.S. Office of Education Team as a program which has achieved statistically and educationally significant results in the attainment of its goals, proved cost effective, and is exportable. Conclusions reported were that Project HEAR had a significant effect in (1) changing stereotypical attitudes toward occupations, (2) increasing preferences for sex-asynchronic occupations for participating elementary school students, (3) increasing knowledge of the world of work for participating middle school students, and (4) increasing the consistency of occupational preference with interests for participating secondary school students. The three multimedia packaged learning units for each level and inservice training programs are described. (TA)
