Research frequently neglects the important ways that race and gender intersect within the complex structural dynamics of STEM. Diversifying STEM fills this void, bringing together a wide array of perspectives and the voices of a number of multidisciplinary scholars. The essays cover three main areas: the widely-held ideology that science and mathematics are value-free, which promotes pedagogies of colorblindness in the classroom as well as an avoidance of discussions around using mathematics and science to promote social justice; how male and female students of color experience the intersection of racist and sexist structures that lead to general underrepresentation and marginalization; and recognizing that although there are no quick fixes, there exists evidence-based research suggesting concrete ways of doing a better job of including individuals of color in STEM. As a whole this volume will allow practitioners, teachers, students, faculty, and professionals to reimagine STEM across a variety of educational paradigms, perspectives, and disciplines, which is critical in finding solutions that broaden the participation of historically underrepresented groups within the STEM disciplines.
