The Getty Center for Education in the Arts has worked with teacher education institutions to develop ways of improving professional preparation to teach art at the elementary and secondary grade levels. Individual campus projects carried out at 10 preservice teaching institutions are summarized: Brigham Young University, California State University at Sacramento, Florida State University, Indiana Unversity, Northern Illinois University, Ohio State University, University of Kansas, University of Nebraska (Omaha and Lincoln), University of Oregon, and Texas Tech University. The remainder of the report considers concepts, themes, and generalizations developed at the Snowbird II seminar in Los Angeles in 1989. Factors that strengthen and inhibit the development of quality discipline-based art education (DBAE) preservice programs are outlined. Seven inhibiting factors and strategies for overcoming them are discussed including conceptual entrenchment of colleagues and students such as child-centeredness in the schools, the complexity of DBAE, insufficient time for faculty to plan and develop programs and courses, lack of an adequate research base, and insufficient funding.
