Based on a groundbreaking 5-year research study conducted by the Early Childhood Research Institute on Inclusion, this book explores the barriers to and influences on inclusive education settings for young children. Topics covered include individualized instruction, family perceptions of inclusion, and cultural and linguistic diversity. The articles draw useful implications for practitioners, providing helpful suggestions for modifying activities, materials, environmental supports, and teaching strategies. The chapters are: (1) "Learning about the Barriers to and Facilitators of Inclusion for Young Children with Disabilities" (Samuel L. Odom); (2) "'I Know It When I See It': In Search of a Common Definition of Inclusion" (Ilene S. Schwartz, Susan R. Sandall, Samuel L. Odom, Eva Horn, and Paula J. Beckman); (3) "Classroom Ecology and Child Participation" (Samuel L. Odom, William H. Brown, Ilene S. Schwartz, Craig Zercher, and Susan R. Sandall); (4) "Classroom Models of Individualized Instruction" (Eva Horn, Joan Lieber, Susan R. Sandall, Ilene S. Schwartz, and Ruth A. Wolery); (5) "Social Relationships of Children with Disabilities and Their Peers in Inclusive Preschool Classrooms" (Samuel L. Odom, Craig Zercher, Jules Marquart, Shouming Li, Susan R. Sandall, and Pamela Wolfberg); (6) "Collaborative Relationships among Adults in Inclusive Preschool Programs" (Joan Lieber, Ruth A. Wolery, Eva Horn, Jennifer Tschantz, Paula J. Beckman, and Marci J. Hanson); (7) "Family Perceptions of Inclusion" (Paula J. Beckman, Marci J. Hanson, and Eva Horn); (8) "Community Participation of Children with Disabilities" (Paula J. Beckman and Marci J. Hanson); (9) "Social Policy and Preschool Inclusion" (Samuel L. Odom, Ruth A. Wolery, Joan Lieber, and Eva Horn); (10) "Cultural and Linguistic Diversity: Influences on Preschool Inclusion" (Marci J. Hanson); and (11) "So What Do We Know from All This? Synthesis Points of Research on Preschool Inclusion" (Samuel L. Odom, Ilene S. Schwartz, and ECRII Investigators). Two appendices include a summary of the initial study, the Ecological Systems study; and study site program descriptions. (Each chapter contains references.) (HTH)
