Khan Academy versus Distance Calculus Comparison

Khan Academy is a wonderful resource for calculus and other subject instruction, featuring video lectures on a massive number of topics.

Khan Academy is free. Usually Khan Academy is used by teachers to assign to their students the watching of various lectures in support of their courses, or for students who are seeking help with their homework and looking for extra instructions.

Keep in mind, however, that these Khan Academy "courses" do not grant academic credit. They are presented more as a resource for learning, and certainly an awesome resource! But if you "enroll" in one of these courses and start engaging the course materials and lectures, you will not be on a path towards earning academic credits for these courses.

Perhaps someday Khan Academy courses will grant academic credit, but for now, they do not.

If you are looking for a non-credit alternative to just learn the course materials, Khan Academy is an excellent resource.

But if your goal is to earn academic credits for your Calculus course effort, you need to seek out an academic credit-granting program, like Distance Calculus @ Roger Williams University.

Review: I took Calculus II through Distance Calculus and can't recommend it enough. Being able to take the course at my own pace while I was working full time was tremendously helpful, especially since I hadn't taken a math course for 5 years prior. The instruction was excellent and the software they used to teach the course was intuitive and facilitated the learning process very well. This calc II class enabled me to take multivariable calc, linear algebra, and real analysis at Harvard University's extension school, which ultimately qualified me for the economics PhD program that I will graduate from next year. 8 years on, I'm still grateful to Professor Curtis and Distance Calculus.

Review: Is the course perfect? No. However, it was by far the best option available. I have learned quite a few things not normally taught in a Calculus course. However, the course lacks a lot of paper solving and integrating, which is to be expected in an online course.

Review: Dr. Curtis's courses are very difficult, but they are definitely worth it! I took Calculus 2 from Dr. Curtis in my senior year of high school and went into a combined Calculus 2 and Calculus 3 course my first year of college. This course prepared me, and I found that I already knew much of the Calculus 3 coursework. The most difficult part of these courses, in my opinion, is pacing yourself. If you can keep yourself on track, then you are all good to go!

Course was good and fast. I don't like math so I can't say it was fun or anything. Grader was very nice. Software was ok.

I have difficulty learning calculus based math, akin to dyslexia when examining the symbolic forms, equations, definitions, and problems. Mathematica based calculus courses allowed me to continue with my studies because of the option of seeing the math expressed as a programming language for which I have no difficulty in interpreting visually and the immediate feedback of graphical representations of functions, equations, or data makes a huge impact on understanding. Mathematica based calculus courses should be the default method of teaching Calculus everywhere.

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.
