This chapter, by Zong Vang, Eric Brunsell, and Elizabeth Alderton, addresses the inclusion of scientific argumentation in elementary classrooms and its connection to the Next Generation Science Standards (NGSS). It begins by discussing the importance of scientific argumentation and describing a powerful framework for constructing explanations and engaging in argumentation. An instructional sequence is introduced for embedding argumentation into science teaching by activating prior knowledge, building content knowledge, and critiquing and revising explanations. Practical strategies are identified that can be used with elementary students to introduce, practice, and support argumentative writing and discourse. Teacher background information, standards, assessments, references, and resources are provided. This book selection also includes the Table of Contents, Foreword, Preface, Acknowledgments, and Index.
