Health administration students attending a college or university in Los Angeles, California, participated in a study of the effect of cooperative education. Three groups of students were selected. Group 1 consisted of undergraduate minority students--five males and five females (19-28 years old) with no prior health related work experience. Groups 2 and 3 were graduate students majoring in health services administration. Group 2 was comprised of 10 males and 5 females (22-46 years old). Group 3 consisted of 5 males and 10 females (21-48 years old). Groups 1 and 2 performed their cooperative experience in the first year of the study, Group 3 students in the following year. After administration of pretest questionnaires, students were placed in a health-related agency under the supervision of a professional health administrator for a minimum of 11 weeks. The posttest was the same questionnaire used for the pretest. A Likert-type attitude questionnaire measured students' feelings about themselves and about becoming health professionals. The semantic differential instrument assessed students' feelings toward five concepts: hospital, cooperative education experience, administrator, health career, and student's skill in administration. Data analysis indicated no significant change between pretest and posttest scores on the attitude questionnaire for any group. Group 3 showed a significant change in attitudes toward the skill of administration. (17 references) (YLB)
