## Philosophy

My goal as a teacher is to affect change in students. I endeavour to be an enthusiastic guide and resource for their learning experience. Practically, this means: treating students with respect; encouraging interaction between myself and students; being prepared and engaged; making myself available for extra help; trying to explain concepts in such a way as to build students' intuition and conceptual understanding; and building students' proficiency through examples, quizzes, and assignments.

I have experience teaching undergraduate courses, running tutorials and labs, and coordinating and delivering outreach activities. I am technically saavy and can create novel and interactive online tools to complement and enhance classroom activities.

### Integration as a Riemann sum

The Riemann integral given by \[ \int_a^b f(x) \,dx = \lim_{N \rightarrow \infty} \sum_{i=1}^N f(x_i) \Delta x_i. \] can be approximated by choosing a specific value for \(N\) and a regular parition for the points \(x_i\). The left, middle, and right Riemann sums can be succinctly written as \[ \int_a^b f(x) \,dx \approx R(\alpha, N) \equiv \Delta x \sum_{i=0}^{N-1} f\bigl(a + (i + \alpha) \Delta x\bigr), \qquad \Delta x = (b-a)/N \] for \(\alpha = 0, 0.5, \) and \(1\) respectively. For a specific example we consider the function \[f(x) = 1 + \frac{8}{10} x^3\] drawn in red and integrate it from -1 to 1. The blue rectangles represent the terms of the (approximate) Riemann sum.Using the controls below to increase/decrease the number of terms \(N\) in the Riemann sum, and to alter the \(\alpha\) parameter used to determine where the function is sampled within each cell, we can see a visual representation of the Riemann sum \(R(\alpha, N)\) above.
