Updated in response to research and reader feedback, the second edition of this popular guide is more user-friendly than ever. The new two-part format breaks the information into practical sections. Section I details how to use activity-based intervention (ABI) with children from birth to 5 years. Then Section II provides a concise history of developments in early intervention and explains why ABI effectively promotes naturalistic learning opportunities. In this edition, readers will find forms for identifying and prioritizing IEP/IFSP goals, discussion of specific disabilities, an appendix of activities, and tips for working with children from diverse backgrounds. Child-directed techniques and ready-to-use forms make it easy for teachers and interventionists to match developmental levels, plan and execute program schedules and activities, and monitor children's progress.
