In addition to teaching at JHU, I work with the Modern States Education Alliance to provide a free education in elementary mathematics. I have collaborated with MSEA and IBL to produce publically available online courses in mathematics ranging from algebra to basic calculus. I hope these materials are of use to students pursuing self-education, preparing for college, or just trying to brush up on basic skills and concepts. Our goal is to make access to this fundamental material open and engaging. Please contact me with questions or comments about these free courses.

I have developed courses in College Algebra, College Mathematics, and Pre-Calculus. The College Algebra and College Mathematics courses have been endorsed by the College Board--I hope you find them useful.
