In 1990, I was part of a group (the Calculus Consortium based at Harvard)
which was awarded a 5-year grant from the National Science Foundation to
rethink the way college calculus should be taught. As an outgrowth of this
grant we developed a new philosophy and syllabus of teaching calculus that
focused on real-world applications, integrating numerical and graphical
approaches with the traditional algebraic viewpoint. The ideas produced
by the consortium were woven into a series of textbooks, now in their 4th
edition, and published by Wiley, and translated into five languages.
