This paper is based on two visits to LaGuardia Community College: one by Norton Grubb in October 1993 to examine both learning communities and the co-op program as part of a larger study of teaching in community colleges, and a second by Norena Badway in April 1995 to look more specifically at the co-op program and the co-op seminars. We want to thank the many administrators and instructors at LaGuardia; we experienced the greatest openness and cooperation in our visits. We particularly would like to thank Harry Heinemann, Dean of Cooperative Education; Catherine Farrell, Associate Dean of Cooperative Education; Jeff Weintraub, Director of Research Evaluation and Systems; Julio Ortiz, college assistant in Cooperative Education; and Roberta Matthews, Dean of Instruction. We received helpful comments on an earlier draft from Harry Heinemann and Catherine Farrell, as well as from Gregg Duncan and John Wirt of the Office of Technology Assessment. Some of this research has been supported by the National Center for Research in Vocational Education, the University of California at Berkeley, under a grant from the Department of Education. The analyses and interpretations in this paper are our own, however.
