In June 1988, 28 principals and assistant principals from public and private schools throughout New Mexico gathered for the first Summer Institute, sponsored by the New Mexico Principals' Center. The goals of the meeting were to share professional knowledge, to engage in "reflective practice," and to construct personal and professional statewide networks. A participant-staff roster is provided, followed by a preliminary typology of administrative "problems" in schools. Included is the banquet address by James P. Miller, Sr., in which he emphasizes the need for management quality in the schools and school districts. Next, a paper by Bruce Barnett, institute consultant, presents the logic of the conceptual framework for the case records that follow. The paper is entitled:"Reflection: The Cornerstone of Learning from Experience," and dwells on a model for reflective thought emphasizing that reflection stimulates action. Twenty-three cases are recorded. (SI)
