This paper traces the development of a human relations program as part of the teacher education curriculum at the University of Maryland Baltimore County. Four approaches are presented--a basic encounter model, a cognitive model, a programed unit, and a final integrated model that is now being employed in the teacher education program. Each model is described briefly with evaluations, perceived limitations, and research results presented. The integrated model, a 5-week experience-based unit consisting of role playing, interpersonal exercises, videotapes, critical incident films, and discussions, was adopted as the most successful of the four attempts. Research results indicated that participants increased their levels of sensitivity to their own feelings, increased their ability ot express their feelings, and increased their capacity for warm, meaningful relationships. Many students also reported this to be the most meaningful educational experience in which they had ever participated. (Author)
