This collection of articles describes an interdisciplinary cooperative effort in the context of PREP (Prekindergarten Education Program) intervention. The PREP began with the intention of developing a culturally competent education system for Hawaiian children and their families. An introductory chapter "Applied Research and Program Development: Orthogonal or Complimentary Behavior?" (Richard N. Roberts) and introductory remarks by Irving E. Sigel are followed by sections on: (1) the social, and (2) the educational contexts of development in the home. The 11 chapaters in these two sections are: "Growing Up Hawaiian: Autonomy and Solidarity in a Generational System of Interaction" (John J. D'Amato and Kristina Inn); "Kin and Calabash: The Social Networks of Preschool Part-Hawaiian Children" (Dale C. Farran, Jayanthi Mistry, Michelle Ai-Chang, and Hannah Herman); "Unpackaging Cultural Effects on Classroom Learning: Hawaiian Peer Assistance and Child-Generated Activity" (Thomas S. Weisner, Ronald Gallimore, and Cathie Jordan); "Development of the Home-Learning Environment Profile" (Robert W. Heath, Paula F. Levin, and Katherine A. Tibbetts); "Mother-Child Interactions and the Development of Verbal and Perceptual Skills in Part-Hawaiian Preschool Children" (Dale C. Farran and Thomas Darvill); "Quality and Quantity of Maternal-Child Interaction" (Richard N. Roberts and Margaret L. Barnes); "The Relationship Between Talking at Home and Test Taking at School: A Study of Hawaiian Preschool Children" (Mary Martini and Jayanthi Mistry); "The Social Context of Early Literacy in Hawaiian Homes" (Paula F.
