This research synthesis provides insight into issues related to teacher diversity and faculty development. It begins with a review of the literature on models of professional development and the characteristics of effective professional development identified by research, with the knowledge that little, if any, research has addressed professional development with diverse teachers. The next section discusses factors to consider when planning professional development (school or institution structures, design of professional development experiences, time factors, and teacher change factors). The third section focuses on diversity and culture, including the characteristics of deep culture, and discusses the American dream as it applies to a diverse and inclusive United States. Finally, the publication puts forth implications for professional development in light of the expanding diversity of U.S. educators. It examines the role of culture in current professional development models and the cultural and contextual variables that are key to providing effective professional development in diverse settings for diverse teachers. Nine steps for developing effective faculty development for diverse teachers are described. (Contains 37 references.) (SM)
