Letters of Recommendation for Distance Calculus Students

An academic letter of recommendation is a letter, typically written by an instructor or professor, about a student and for a student. It is shared either directly with the student or (more often) sent confidentially at the student's request to a college, university, graduate program, or employer.

Why Letters Vary So Much in Quality

Letters of recommendation range enormously in depth and usefulness. On the low end, an overburdened instructor may write something generic:

TO WHOM IT MAY CONCERN:

Ms. Jones was a student in my Differential Equations course. She earned an A-. She completed all of her homework on time.

On the high end, when the instructor has had genuine, sustained interaction with the student, seen exceptional work, watched the student grow over the course of the term, and observed specific moments of insight or perseverance, the letter can be substantially richer and more credible to admissions committees.

Both undergraduate and graduate school applicants now routinely need multiple letters of recommendation from prior teachers, instructors, or professors. Letters are also standard fare for many employment applications.

The Lecture-Hall Problem

A student who takes Calculus in a 200- or 500-seat lecture hall faces a real difficulty when it comes time to ask for a recommendation: the lecturer may not actually know them. Many students in that situation visit office hours weekly precisely to build enough relationship that a meaningful letter is even possible at the end of the term.

Why Distance Calculus Is Different

The pedagogical format of Distance Calculus is built around intensive student-instructor interaction. The recursive back-and-forth on every assignment is, in effect, a continuous office-hours conversation - sustained over weeks or months, on real mathematical work that the professor has seen the student think through in detail.

Add to that the multiple evaluation tools - mastery-graded recursive homework, take-home final exams, the proctored final exam, and the final video portfolio - and the head professor, Dr. Robert Curtis, has an unusually rich set of evidence to draw on when writing a letter. The result is letters that contain specific, concrete observations about the student's work, not generic boilerplate.

Who Can Request a Letter

Distance Calculus has a healthy spread of grades - A's, B's, and C's all appear in completed courses. Earning a B or even a C does not automatically preclude a positive letter. On request, Dr. Curtis will review your gradebook and course conversation transcripts and tell you honestly whether he can write a strong letter for you.

Students who earn solid A grades are in the strongest position for a favorable letter.

Letter of Recommendation Interview (Optional)

Students who request it can schedule an optional Letter of Recommendation Interview after the course concludes. In that conversation, the professor and student discuss the student's academic goals, the points the student would like emphasized, and the specific undergraduate/graduate programs where the letter will be sent. This produces a letter that is genuinely tuned to the student's intended next step.

How and When to Ask

If earning a letter of recommendation is part of your academic goal set, reach out to Dr. Curtis early: ideally near the beginning of the course (so the professor knows your goals from the start) and again near the end. The earlier the conversation begins, the more concrete material there is to draw on when the letter is written.

Well organized and well explained content. Professor did a great job. I learned a lot.

Dist Calc saved a ton of hassle and time having to take calc at a local community college, which realistically would have delayed my entrance to BU LEAP by at least a year.

Would strongly recommend it.

A lifesaver. When I found out I needed a course done in the last weeks of summer I thought there was no way i'd find one available, but this let me complete the course as quickly as I needed to while still mastering the topics. Professor always got back to me very quickly and got my assignments back to me the next day or day of. Can't recommend this course enough for students in a hurry or who just want to learn at their own pace.

I found the courses to be informative, enjoyable, and most importantly, effective in helping me learn the concepts of calculus. My math skills were always very weak, and I had a great deal of difficulty passing my undergrad math courses.
The pace of a traditional classroom setting was just too quick for the concepts to really sink in. With Distance Calculus, I had courses that were taught with the full rigor of an on-campus class, but where I could take my time and really learn the material...all while having access to top-tier instructional help for real math professors and assistants.

DC gave me the tools and the confidence I needed, so after successfully passing my DC courses, I moved on and completed a master's degree in CS.

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.
