This book is a collection of essays by various authors documenting the development and evaluation of Individually Guided Education (IGE), a planned attempt, involving thousands of scholars and practitioners, to produce more effective elementary schools. Part 1, "An Attempt to Restructure Elementary Schooling," consists of three chapters describing IGE. Chapter 1 delineates the assumptions of IGE in the context of school reform efforts of the past quarter century. Chapter 2 outlines the intentions, components, and implementation strategies of the IGE program, while chapter 3 describes the plan for evaluating IGE. In part 2, "The Effects of Planned Change," five chapters summarize the evidence gathered in the IGE evaluation project. Chapter 4 summarizes the data concerning whether IGE "really happened" in schools, while chapters 5 to 8 summarize the findings from each of the four phases of the project: a large sample causal study, on-site validation of IGE implementation, a field study of six IGE schools, and five curriculum studies. Part 3 concludes the book with a single chapter (chapter 9) discussing the implications of IGE and its evaluation. A list of presentations and publications associated with the project is included.
