MATHEMATICAL ASSOCIATION OF AMERICA CSPCC, NSF #0910240 Precalculus to Calculus: Insights & Innovations David Bressoud St. Paul, MN University of Saint Thomas Saint Paul, MN June 16, 2016 PDF file of these slides available at www.macalester.edu/~bressoud/talks
Today we teach greater numbers of students, who are less prepared, using fewer resources, and with increased expectations for student success.
