This book examines U.S. progress in revitalizing teacher education and reforming K-12 education via Professional Development Schools (PDS's). The book discusses whether PDS's are: improving K-12 curriculum and instruction through faculty development; making substantive, positive differences in students' learning levels; addressing the needs of marginalized or vulnerable learners; merging with other reform initiatives; and meeting time and financing challenges. Data come from mainstream and fugitive sources, including student interviews and followup studies with teacher education graduates; surveys with preservice teachers on attitudes, beliefs, and self-efficacy; and reviews in student journals. Chapter 1 examines features and practices characterizing initial teacher preparation and professional development for teachers in PDS's, considering the impact of teacher development on participants. Chapter 2 examines activities, characteristics, and outcomes of PDS programming that target student achievement, discussing inquiry in PDS's and inquiry about PDS effectiveness. After summarizing major concepts that define teaching and learning in PDS's, the chapter describes programs that attempt to implement practices reflecting these concepts and themes. Chapter 3 examines problems of time and financing in PDS's, exploring additional fiscal and human resources necessary to start up and sustain them. Chapter 4 summarizes the benefits of parent involvement, integrated services, and technology infusion, examining the extent to which PDS programming incorporates them. Chapter 5 describes the extent to which equity of diversity-related programming and practices in PDS's reflects unequal power relationships between and within schools and universities and between historically dominated groups and schools, universities, and society.
