This self-instructional module, one volume of a series of competency-based modules in human relations skills for occupational specialists, is designed to help the specialist develop an understanding of the importance of group dynamics in vocational development and decision making. Other modules in this set of three are Human Relations Skills in Individual Interactions for the Occupational Specialist, and Level I Human Relations Skills for the Occupational Specialist Working with Groups. The module provides a prospectus, which details objectives and explains how to use the module; a flow-chart, which illustrates the self-instructional process; a pre-assessment quiz; and a work plan in chart form. Instructional activities (reading assignments and learning activities) are listed for each of the 10 enabling elements or lessons. The enabling elements deal with the use of vocational group counseling, beginning a group, stages of group development, group leadership skills, building and maintaining a group, problem members and anti-group roles, facilitating group involvement, specialized formats and special populations, sharing the leadership function, and ethical standards for leadership. Each lesson includes a worksheet and a self-test; a post-assessment covering the entire module and a bibliography complete the booklet. (JAC)
