Three presentations are provided from Symposium 39, Integrating Learning with Working, of the Academy of Human Resource Development (HRD) 2000 Conference Proceedings. "Constructing Knowledge in Continuing Professional Education [CPE]" (Barbara J. Daley, Merryl Carlsson) reports an analysis of the interrelationships between professional practice, knowledge gained in CPE programs, and context of employment that found professionals construct a knowledge base by moving back and forth between CPE programs and their professional practice. "How Important Is Education for Learning To Work?" (Richard J. Torraco) addresses the following: (1) reviews literature on work and the expertise needed to perform it, from studies of both individual and collective expertise; (2) examines the research methods available for conducting such studies; and (3) proposes a framework for further study of the issue of integrating prior learning and experience with the present demands of a task to perform it skillfully. "Critical Reflection on the Shop Floor" (Marianne van Woerkom, Wim. Nijhof, Loek F. M. Nieuwenhuis) reports a study describing on-the-job learning that found flexible craftsmanship is no neutral measure of output because it takes into account only the employer's view of ideal employees. Critical reflection is suggested as a more neutral measure. The papers contain reference sections. (YLB)
