In this study, we investigated ream-based community service projects as act
ion learning initiatives designed to facilitate two learning outcomes: comm
unity learning (knowledge of social, cultural, or economic issues) and pers
onal learning (self-awareness of managerial attitudes and abilities). We de
veloped hypotheses to predict critical input conditions for action learning
that promote community and personal learning. We tested these hypotheses w
ith data collected from 381 MBA students and their team leaders who partici
pated in a variety of community service projects. Results demonstrated that
design conditions (task characteristics, social interactions, and affectiv
e responses) influenced community and personal learning differently. We sup
plemented survey results with interview and observational data from a subse
t of participants and conclude with a discussion of the theoretical implica
tions for action learning and practical recommendations for designing commu
nity service programs. Copyright (C) 2001 John Wiley & Sons, Ltd.
