Investigations create three-dimensional learning experiences that include a variety of access points. This Part 2 covers how investigations engage students in purposeful observations, reading, and writing, as well as applications of technology. Suggestions are also provided on how to build an environment to support investigations. Teacher background information, standards, assessment, video links, and other references and resources are provided. This book selection also includes the Table of Contents, About the Authors, Support Resources, References, and Index.
