In this chapter, the details of the practice of obtaining, evaluating, and communicating information are outlined and examples and resources provided related to implementing the practice. We hope that this information will help teachers and others learn more about this practice and learn ways to support students as they participate as part of their investigative work in K–12 science classrooms. Students will need support and a myriad of opportunities to engage in the practice when learning how to effectively obtain, evaluate, and communicate scientific and engineering-related information. Yet, it is worth the effort for both students and teachers because the skills and competencies are useful not only to students in their K–12 science education but also to other ventures. A list of materials, teacher background information, standards, assessment, and references are provided. This book selection also includes the Table of Contents, About the Editors, Contributors, Acknowledgments, and Index.
