Grades

With the Distance Calculus course pedagogy (teaching strategy) based upon Mastery Learning, the concept of grades calculated with point accumulation is not applicable: all of the student's homework is expected to be completed at 100% correct, so getting anything less than an "A" on your homework is not possible.

Accordingly, to base a student's grade (solely) on a proctored, written final exam, is not a realistic and fair assessment of the student's gained knowledge in the course.


Therefore, we have devised the following combination of different evaluations to fairly and accurately determine an earned grade in a Distance Calculus course.

The options for the "C" Grade are intended to accommodate the student who needs to finish the course quickly, and the final grade is of less importance than completing the course post haste.

The 48-hour Take-Home exams are completed independently by the student, under the honor system, with the use of the computer algebra software. These Take-Home exams are a bit more challenging, usually 8-10 questions each, meant to be completed in 2-3 hours student work time, and are not graded recursively. The 48-hour time period is provided to accommodate students with work/family/life schedules that are not necessisarily predictable (i.e. the take-home exams don't take 48 hours to complete!) A very high percentage of students who finish a Distance Calculus course earn an "A" grade; the take-home exams are meant to measure the student's knowledge upon completion of the course, rather than "lower the curve" as they say.

The proctored, written final exam is the same for all three grade levels, and completed without the use of computer algebra software or other notes or aides. This proctored final exam is conducted at the student's location via Skype video call with the instructor, or, alternatively under the supervision of a proctor pre-approved by the instructor. Final Exam proctors are proposed by the student, and must be one of the following:

  • a Librarian at a local library (public, or school/college/university), or
  • a Teacher at a local school/college/university, or
  • an Official at a place of worship (church, temple, mosque, et al.)
[Note: Final Exam proctors at your location are usually very easy to identify and get approved - don't worry about this until you near the completion of your course work.] The proctored final exam is completed within a 2 hour time limit; as our completing students are exceptionally well-prepared, the vast majority of completing students report that the proctored final exam "was easier than I thought it would be."

The Final Video Portfolio is a set of screen videos that the student makes answering a set of questions posed as part of the final exam process. It is similar to "come to the board and complete this problem" as you might be asked to do in a classroom course. Final Video Portfolios are generally 5-10 questions to complete in video format.

C "C" Grade - Either Path Below
Path 1 - Full Coursework
  • Complete all course assignments at 100% correct (recursively graded)
  • Complete Final Video Portfolio (5+ problems)
  • Score 60% or higher on the proctored written final exam
OR
Path 2 - "C Path" Core Subset
  • Complete the "C Path" subset of core assignments at 100% correct (recursively graded)
  • Complete Final Video Portfolio (5+ problems)
  • Score 70% or higher on the proctored written final exam
B "B" Grade
  • Complete all course assignments at 100% correct (recursively graded)
  • Complete the 48-hour "B-Level" Take-Home Final Exam at 70% or higher
  • Complete Final Video Portfolio (7+ problems)
  • Score 70% or higher on the proctored written final exam
A "A" Grade
  • Complete all course assignments at 100% correct (recursively graded)
  • Complete the 48-hour "B-Level" Take-Home Final Exam at 80% or higher
  • Complete the 48-hour "A-Level" Take-Home Final Exam at 80% or higher
  • Complete Final Video Portfolio (10+ problems)
  • Score 70% or higher on the proctored written final exam

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 was the best class! So much more interesting doing the computer math than a boring lecture class. Diane was so responsive and helpful. I recommend this course.

Courses Completed: Calculus II
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.

Courses Completed: Calculus II, Multivariable Calculus, Differential Equations, Linear Algebra
After completing all the math offered by my highschool, I switched over to Roger Williams for Calculus II and onward. Overall, it has been a pretty great way to understand the topics online, with transferrable college credits. The exams are not terrible, and the courses cover the vast majority (if not all) of topics covered by traditional courses, with some unique ones added to. So far, I have taken four courses, with another one or two before I graduate.

The only problem with the course is the lack of pen and paper work. This shouldn't come as a crazy surprise with an online course, but there is not much emphasis on symbolic computation. Mathematica or other software does most of the heavy computation for you. The lectures usually show how to solve the problems through paper, but those skills are rarely put into practice. Literacy Sheets act as a way to do some of that (especially with the Calculus II & III course).

All in all, this isn't a huge issue. I just memorize and practice things like double integration, Laplace, ODE solving, matrix diagonalized form, row operations, etc. With a little outside work, this resolves itself. Without Roger WIlliams, I probably would not have been able to take any of these math courses in highschool.

So overall, a great choice for highschool advanced math, especially with transferrable credits.

The professor as well as the TAs give great feedback when you need help with problems and the videos are great at explaining concepts. Return time on work is good and the work is not too much to handle.

Courses Completed: Linear Algebra
This course gives a perspective on Linear algebra that no traditional course does. I’d say i gained much more intuition for this subject from the DC course than my friends who took traditional courses elsewhere. As a cs major, this version of learning with visualization has helped me a lot in understand ML models. However the course doesn’t have videos for the last 2 chapers so i had to self learn with the mathematica notebooks. Response times are a little slow but since it’s a remote class, i guess it’s justified. Overall amazing course and definitely take this over traditional lin alg classes.
