This workshop was undertaken to exchange, through face to face interaction, theoretical formulations on adult education and the social sciences; and to provide adult educators with opportunities to learn more about theory building principles and strategies. Papers for the first day discussed research dissemination and utilization, measurement of participation, interrelationships between theory and practice, and concepts in extension education. Other papers dealt with principles of adult learning, organizational structures and changes, kinds of theories and resources, adult learning projects, interactions between people and materials in instructional situations, margin theory (pertaining to the adequacy of an adult's intellectual resources for maintaining autonomy), and an approach to model building based on the elements of family, community, work institution, ego or personality, and one's physical being. A summary discussion was held to evaluate the workshop and to decide whether to schedule another such meeting. (Appendixes include seminar participants and 20 references. Appendix A removed because of poor reproducibility.) (ly)
