This chapter summarizes the four tasks of the team. By understanding the far-reaching charges to address diversity and equity across many related topics and products, readers will appreciate how the interests of diverse student groups were taken into account throughout the NGSS writing process. In particular, the team members wrote the seven case studies presented here so readers can find utility in the case studies for their teaching practices. Teacher background information, standards, assessments, and references are provided. This book selection also includes the Table of Contents, About the Editors, Contributors, Preface, and Index.
