A study examined the effect of a series of enrichment activities on the self-concept of 34 cooperative office education students in the East Baton Rouge School Parish (Louisiana). The students participated in an enrichment program consisting of 10 55-minute class periods of instruction in human relations and communication skills, ways of coping with stress and conflict, time management, physical fitness, success in the business environment, and motivation. A diagnostic tool called Personal Profile System was used to assess the self-concept of the 34 students. Next, the Tennessee Self-Concept Scale was used to compare the self-concept of the students in the treatment group with that of cooperative office education students in a control group. Although there were no statistically significant differences between the treatment and control groups, students in the treatment group liked the enrichment activities and found them to be useful self-assessment tools. The fact that the materials helped the students view themselves critically, identify their weaknesses, and formulate plans for improvement might explain why their self-concept scores did not increase between the pre- and posttests. (Appendixes to this report include discussions of the Personal Profile Instrument and Tennessee Self-Concept Scale and an analysis of the study's covariance source tables.) (MN)
