Active Preparation for Calculus

Back in May, I wrote of my pending fall 2018 sabbatical and plans to write a textbook for the calculus-prep course that we now offer at GVSU.  I’m pleased to share that a complete draft of my latest free, open-source text, Active Preparation for Calculus, is now publicly available in HTML, PDF, or its original PreTeXt […]

Followup to my EMES seminar

Online versions of Daily Prep Assignments

More Linear Algebra

Many years ago, Gil Strang wrote a wonderful short essay titled “Too Much Calculus.”  His thesis:  calculus and linear algebra are imbalanced in the curriculum.  Even as the author of a calculus text, I totally agree.  Our students need more linear algebra, more in terms of time, exposure, and understanding. My phenomenally talented friend and […]
