This book explores operational problems of providing educational services to underprivileged children in developing nations and presents reports from countries which have developed programs to solve these problems. The book is designed primarily for specialists concerned with development efforts both within and outside the educational sphere, and for people responsible for the training of professional and auxiliary staff to man such learning delivery systems. Part A explains the purpose of the book and summarizes the content and structure of the programs described in Part B. Part B, which comprises the bulk of the book, contains 17 reports from specific projects at national and sub-national levels. The papers are presented under six topics, including school programs; out-of-school programs; integration of learning components of basic services; actions in favor of infants and very young children; and selected exploratory activities relating to identification of learning needs. Developing countries contributing these papers include India, Madagascar, Sri Lanka, Tanzania, Guatemala, Ethiopia, Mexico, and the Philippines. Part C identifies problems and issues which are common to all educational development efforts, including community participation and learning system design. A bibliography of 60 references concludes the book. (AV)
