This symposium on adult learning and human resource development consists of three presentations. "Adult Learning Principles and Concepts in the Workplace: Implications for Training in HRD" (Margot B. Weinstein) reports on findings from interviews with restaurant employees who reported that training practices using adult learning principles increased their learning and made them feel more qualified and confident, valued and essential to the success of the organization, and increased their collaborative and problem solving skills. "The Legacy of Malcolm Knowles: Studying Andragogy Andragogically" (Mary Boudreaux, Thomas Chermack, Janis Lowe, Lynda Wilson, Elwood F. Holton III) describes the examination of a portion of Malcolm Knowles' personal correspondence and the subsequent creation of a database to index it. "Facilitating Learning with Graduate Students in Human Resource Development" (Barbara J. Daley) describes an investigation of the ways in which constructivist teaching strategies influence learning and examines the positive learning results experienced by graduate students who used concept mapping as a constructivist strategy. The second and third papers contain figures and tables. All three papers include substantial bibliographies. (AJ)
