The Next Supercontinent
Solving the Puzzle of a Future Pangea
Ross Mitchell
University of Chicago Press, 2023

An internationally recognized scientist shows that Earth’s separate continents, once together in Pangea, are again on a collision course.

You’ve heard of Pangea, the single landmass that broke apart some 175 million years ago to give us our current continents, but what about its predecessors, Rodinia or Columbia? These “supercontinents” from Earth’s past provide evidence that land repeatedly joins and separates. While scientists debate what that next supercontinent will look like—and what to name it—they all agree: one is coming.

In this engaging work, geophysicist Ross Mitchell invites readers to remote (and sometimes treacherous) lands for evidence of past supercontinents, delves into the phenomena that will birth the next, and presents the case for the future supercontinent of Amasia, defined by the merging of North America and Asia. Introducing readers to plate tectonic theory through fieldwork adventures and accessible scientific descriptions, Mitchell considers flows deep in the Earth’s mantle to explain Amasia’s future formation and shows how this developing theory can illuminate other planetary mysteries. He then poses the inevitable question: how can humanity survive the intervening 200 million years necessary to see Amasia?

An expert on the supercontinent cycle, Mitchell offers readers a front-row seat to a slow-motion mystery and an ongoing scientific debate.

Testing Deaf Students in an Age of Accountability
Robert C. Johnson
Gallaudet University Press, 2008

Despite the idealism represented by the No Child Left Behind law’s mandate for accountability in education, deaf students historically and on average have performed far below grade level on standardized tests. To resolve this contradiction in deaf education, this collection presents a spectrum of perspectives from a diverse corps of education experts to suggest a constructive synthesis of worthy ideals, hard realities, and pragmatic solutions. Contributors to this study include volume editors Robert C. Johnson and Ross E. Mitchell, Ed Bosso, Michael Bello, Betsy J. Case, Patrick Costello, Stephanie W. Cawthon, Joseph E. Fischgrund, Courtney Foster, Christopher Johnstone, Michael Jones, Jana Lollis, Pat Moore, Barbara Raimondo, Suzanne Recane, Richard C. Steffan, Jr., Sandra J. Thompson, Martha L. Thurlow, and Elizabeth Towles-Reeves.

These noted educators and researchers employ experiences from Massachusetts, Delaware, Maryland, North Carolina, Illinois and California to support their findings about the dilemma facing deaf students and their teachers. They assess the intent and flexibility of federal law; achievement data regarding deaf students; potential accommodations and universal design to make tests more accessible; possible alternatives for deaf student not ready for conventional assessments; accounts of varying degrees of cooperation and conflict between schools and state education departments; and the day-to-day efforts of teachers and school administrators to help deaf students measure up to the new standards. By presenting these wide-ranging insights together, Testing Deaf Students in an Age of Accountability provides a unique opportunity to create genuine means to educate deaf students for the only test that matters, that of life.
