Distance Calculus at Suffolk University is a university-level calculus course program taught entirely via the internet. The course uses the Calculus & Mathematica curriculum, and is conducted on an intensive student-to-instructor basis using internet communication technologies providing the student with a flexible course meeting around their existing schedule. http://www.distancecalculus.com/
Students need to construct their own understanding of each mathematical concept. Hence, we create situations for students that will foster their making the necessary mental constructions. http://www.pnc.edu/Faculty/kschwing/C4L.html
