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.

Distance Calculus - Student Reviews

Courses Completed: Multivariable Calculus, Differential Equations, Linear Algebra
After a really rough first year of calculus, I completed all of the second year calculus courses with Distance Calculus. It was like night and day the difference. My first year was so boring and monotonous. Multivariable Calculus, Differential Equations, and Linear Algebra through Distance Calculus were just so much different - so not boring at all. I thoroughly enjoyed these courses. So engaging.

Courses Completed: Calculus II, Multivariable Calculus
Fantastic courses! I barely made it through Cal 1, and halfway through Cal 2 I found this program. I took Cal 2 and then Multivariable and I just loved it! SOOOOOOO much better than a classroom+textbook class. I highly recommend!

I took the Business Calculus course from Distance Calculus in 2013. I was admitted to my MBA program, but then they told me I needed to take Calculus before starting the program. I finished the Business Calculus course in about 3 weeks in August before my program started. Not the most fun thing to do over the summer, but at least I got it done. Thanks Diane and Distance Calculus team!

Great course. Professor Curtis and the TAs graded quickly and gave really helpful feedback that made the class feel smooth and manageable. Definitely recommend it.

POSITIVES:
One of the best math classes I have ever taken. The lessons made the failures of my previous professors very apparent. In a few short minutes, things that I used to struggle with just clicked. This professor is top notch and really wants you to understand how to use the material.
NEGATIVES:
The SOFTWARE is extremely frustrating. Even after taking the time to learn, there are countless glitches. You learn to work around them, and overall, the software makes the math convenient, but its failures are sorely felt throughout the course. Make sure you save often as it crashes regularly, especially with graphs.
The assignments are easy enough but some of them don't line up with the taught material. Be prepared to do some of your own independent research to get a deeper understanding of why things are the way they are.
