Meet The Distance Calculus Team


Unlike many other distance education courses, ALL instruction, grading, feedback, and interaction with the students is completed by qualified HUMAN instructors. We do not use AI or Multiple Choice or other automated grading mechanisms.

Head Professor: Robert R. Curtis, Ph.D.

robert curtis photo Robert completed his B.A. with Highest Honors in Mathematics at the University of California, Santa Cruz, in 1987, followed by his M.A. and Ph.D. in Mathematics at the University of California, San Diego, in 1993, writing in algebraic geometry with advisors George Kempf and Adrian Wadsworth.

Robert began 1991 teaching at Delta College in California, traveling one day to visit master teacher Phil Smith in his new mathematics computer lab at American River College in Sacramento. Phil's students were learning Calculus II using a new graphical computer algebra program called Theorist, accomplishing long u-substitution integration problems with drag-and-drop ease on the Macintosh, a coupling of computer algebra usage with visual and symbolic learning. The new field of Distance Mathematics Education was born from a single Mac computer in Delta colleague Chris Barker's office, empowering Theorist files to be click-launched on the World-Wide-Web via the new Netscape (now Firefox) browser.

In 1995, Robert moved to Cambridge, Massachusetts to found MathMonkeys, and purchased Theorist in 1999, rebranding it to LiveMath. Robert continues to lead the programming team working on a Qt-based LiveMath to return it full multiplatform glory.

Robert co-founded the Distance Calculus program in 1997, originally at Suffolk University in Boston, Massachusetts; later moved to Shorter University in Georgia, and now at Roger Williams University in Rhode Island, USA, where Robert is the Head Professor and Program Director of the University College program.

Robert adapted the Calculus&Mathematica courseware series into LiveMath, as well as adding to further development of this wonderful curriculum series originally written by Bill Davis and Jerry Uhl, et al. Robert is currently working on the adaptation of the Alfred Grey's Differential Geometry Using Mathematica text to the Distance Calculus platform.

On a good day at low tide, Robert can be found at sunrise on a long beach walk with a thermos of coffee percolating new and interesting ways to experience mathematics empirically with computer algebra.

Amazing professor, extremely helpful and graded assignments quickly. To any Cornellians out there, this is the Calculus Course to take in Summer to fulfill your reqs! I would definitely take more Calculus Classes this way in the future!

This course may be more difficult than your average differential equations course, which better prepares you to use these skills in your degree. The self-learning does make learning some of the concepts challenging, but you get the help you need to understand these concepts.

The courses were excellent. Very flexible and engaging and the platform offers a lot of upper-level courses. Dr. Curtis is an outstanding professor and very responsive. I would take again.

After two failed attempts at my university, this course helped me understand Calculus. The live maths tool along with Dr. Curtis were especially helpful, allowing me to visualize concepts and expand my understanding. The explanations were clear, the examples practical, and I could learn at my own pace, which built my confidence. Thank you.
