Naming What We Know, Classroom Edition examines the core principles of knowledge in the discipline of writing studies, using the lens of “threshold concepts”—concepts that are critical for epistemological participation in a discipline. This edition focuses on the working definitions of thirty-seven threshold concepts that run throughout the research, teaching, assessment, and public work in writing studies. Developed from the highly regarded original edition in response to grassroots demand from teachers in writing programs around the United States and written by some of the field’s most active researchers and teachers, the classroom edition is clear and accessible for an audience of even first-year writing students.
