David's profile
David
University of Pennsylvania
I'm an archaeology PhD student at the University of Pennsylvania with extensive teaching experience at the college level. I've taught at Penn, University of the Sciences, and Methodist University in various social sciences, including anthropology, sociology, statistics, public health, and psychology. As a teacher, I'm guided by the idea that what I'm doing with students should be useful to them long-term. Making topics interesting, relevant, and accessible is of paramount importance because it allows students to hone skills that they'll use for the rest of their lives. Teaching is fun for me because I love getting to facilitate and witness my students' breakthroughs. There's nothing better than getting to that eureka moment!

William's profile

From my experience teaching math to a range of students, from middle school through college, I know that it does not come easily to everyone. However, I firmly believe that everyone has the capability for mathematical reasoning. Everyone has their own strengths and challenges, and my job as a tutor begins with identifying these. I like to have students work through problems while I guide them and make suggestions, so that I can get a sense of what they understand and what they don't. Then we can build on their knowledge and break down the challenging parts of the problem into smaller, more manageable chunks. I hold a bachelor's degree from UChicago and a doctorate from MIT, both in mathematics. I am available to tutor Latin, physics, and all levels of math. Outside of academics, I am an avid tournament chess player, and I enjoy running and cycling.
