Whenever I award a student a course grade of A+, I write a congratulatory email and ask for advice on how to succeed in my classes, which I distribute without modification to students the next time I teach that course.
If you find it difficult to relate to advice from A+ students, here are some unsolicited thoughts from a student in Fall 2021: “First and foremost I'd like to to thank you for a wonderful first semester at university, Math 157 was a great way to kick off the year for me. I've never been good at math and as a result I never really liked the subject in high school but your passion for mathematics proved to be nothing less than contagious. Heading into this course, I admit grades were my main (if not only) focus but it quickly became second to working towards figuring out the intuition behind concepts and really understanding the content. It gradually made sense to me why you kept encouraging us to focus on the underlying concepts instead of solving a specific kind of question in a specific way. It wasn't entirely inspiration that drove me, however, the 40% on my first midterm was motivating to say the least. Watching myself improve over the semester and becoming increasingly confident with the course material was a very rewarding experience and really made the studying worth it. I still am very surprised I got a B- because I was seriously expecting something in the C to D range, even with adjustments. I held off on writing this email until after the letter grade came back for fear of it seeming disingenuous so thank you for filling in the gaps in my learning caused by the pandemic as well as teaching me to think about math in a new and drastically less tedious way.”
In Fall 2024 I'm teaching MATH 480W, The Art and Craft of Problem Solving and MATH 447/747, Coding Theory.
In Spring 2025 I'm teaching MATH 157, Calculus I for the Social Sciences.
One of my favourite courses to teach is MATH 480W, The Art and Craft of Problem Solving, which shows you how to solve problems like:
Six years after completing MATH 480W, a student wrote to me: “Hope you're well! I'm an old student from a few years back, I took your Art and Craft of Problem Solving course and the Putnam a few years back. I'm doing my PhD now in Germany, and was just thinking about your course, while making a diagram of a complicated problem I'm trying to solve. Honestly, I think it was my favourite course I ever took at university, and I still use the strategies I learned all the time. It also gave me a lot of confidence in my problem-solving abilities which really contributed to me being brave enough to take on a doctoral position. So I just wanted to say thanks. Thank you!”
