Mastery Learning

Mastery Learning is an educational pedagogy that structures the course for students to work on assignments until they have 100% understanding and completion.

This is quite different than most mathematics courses, where in a typical math course, you submit your homework assignment, and it is graded with a fixed score, and if you missed any problems, your homework grade is fixed, and thus your course grade is then also fixed.

There are only two grades available on all homework in any Distance Calculus course:

  • "C" = Complete
  • "IP" = In-Progress

Homework in our Distance Calculus courses are recursively graded - back and forth, back and forth - between the student and the instructor/teaching assistant, until all of the problems are completed at 100%. Thus, the only grade possible on the homework portion of the course is: C = Complete.

Students will work on a number of assignments at the same time - "assignments in play". These might be 3, 4, 5, ... or maybe even 10 assignments submitted. While the first 3 assignments are graded, the student might go forward and work on the next 4 assignments, then return to 2 of these graded assignments to complete more work on them, and resubmit them for grading again. Then 4 more of the assignments are graded, and the student revisits some of those to make improvements, while simultaneously working on the next 3 assignments.

As you can see, this is a much different structure than a typical, classroom, synchronous course, where you may have weekly homework assignments due on a Thursday, they are graded over the next week or two, the grade earned is the grade, and it is punitive grading that somehow inspires a student to "do better work the next time".

If a Distance Calculus student consistently turns in poor quality work, that is an indication that the student needs to slow down, and concentrate on a limited number of assignments with more intensity. This is not a punitive situation, and it is usually a temporary limitation placed on the student by the instructional staff. Once the student finds more success on a module, then the student may return to progressing through the curriculum.

Our goal at Distance Calculus is always empowering the student to succeed at the student's highest academic potential. We are not interested in penalizing students for an early bad grade, setting up some artificial point game structure where students are there to simply earn points towards a higher grade. We are about real learning. In an asynchronous course structure with a 1 year time completion deadline, we have the flexibility to engage in rigorous, recursive grading feedback structures that promote true student succcess.

Grades are determined in a very different way than traditional courses. Our grading and exam system is a time-honored multi-modal measurement of a student's true learning level of the course topics.

Often Distance Calculus students feel that they have worked much harder in this course structure than when compared to similar courses in a traditional, classroom, synchronous-based system. Both systems have their merit and strengths and weaknesses. This is one reason why Distance Calculus is a wonderful alternative for students looking for a different academic experience.

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.

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.

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.

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.

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.
