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)

  • 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







Distance Calculus - Student Reviews

Courses Completed: Linear Algebra
Online learning for math is certainly a different way of learning than most are used to in school - However, Distance Calculus does a great job of providing valuable feedback and tips on each assignment, and the professor is always available for detailed instruction and help. Tools like Mathematica provide an environment for learning with a lot more freedom and opportunity for exploration of concepts than the regular classroom setting.

Probability Theory was a great course. Very very thorough. I thought it would never end :). I was very prepared for my coursework in economics. Excellent refereshher of derivatives and integrals - really forced me to remember that stuff from freshman cal.

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.
