Who Will Be My Instructor?


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.

A lifesaver. When I found out I needed a course done in the last weeks of summer I thought there was no way i'd find one available, but this let me complete the course as quickly as I needed to while still mastering the topics. Professor always got back to me very quickly and got my assignments back to me the next day or day of. Can't recommend this course enough for students in a hurry or who just want to learn at their own pace.

Courses Completed: Multivariable Calculus
Im a visual learner and had a difficult time understanding multivariable calculus my first go around, and found this course offered by Roger Williams University, which uses real-time 3d graphing of the equations. I would see my work be manipulating the models, which gave a robust understanding of what each variable did. absolutely loved the course and class recordings.

I highly recommend this course! Dr. Curtis is the best teacher and is ALWAYS willing to work with you to make sure you understand the subject. It was definitely a positive experience and the credits were transferred to my University with no problems! I definitely do not regret it and I had doubts in the beginning but if I had to, I would do it all over again!

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.

Courses Completed: Calculus I
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.
