At approximately 3:30pm on a Tuesday afternoon in mid-July, 2000,
I was completely baffled. There I sat, dressed in khaki pants
and a polo shirt, in a nice leather chair with my arms folded
on a mahogany table in a meeting room at Lockheed Martin Naval
Electronics & Surveillance Systems in Syracuse, NY. Surrounded
by some of the most brilliant minds I had ever encountered, I
winced in the middle of this discussion of a high-tech research
and development project as I painfully listened to their futile
attempts to communicate with each other. Individually, these engineers
had some amazing ideas. Imagine what could be accomplished if
only they had the ability to effectively share their ideas with
each other, I thought. This phenomenon is by no means endemic
to Lockheed Martin in Syracuse, NY. I experienced this same bewilderment
in many other internships I have had over the past few summers
and would venture that in most companies, especially in technical
fields, this inability to communicate ideas runs rampant. As we
venture into the twenty-first century, the need for mathematicians
and computer scientists in industry and the government is growing.
From computer scientists developing new technologies at IBM to
mathematicians developing new cryptographic algorithms at NSA,
in order to stay on the cutting edge it is crucial that the people
working in these sectors have the ability to verbalize technical
ideas in a way that others can understand.
As I barely heard a five minute conversation that should have
taken ten seconds, my thoughts wandered to some of my mathematics
and computer science classmates at Colgate University. While the
liberal arts education had endowed most Colgate students with
effective communication skills, they seemed to have eluded many
of my math and C.S. colleagues. I could name many bright students
who could breeze through a problem set or programming assignment
but could not explain their work to someone else if their life
depended on it. It kind of makes sense, I thought. Unlike most
humanities or social science majors, math and computer science
students do not have many chances to practice communicating their
ideas to others. Why does this have to be the case? I decided
at that moment that it doesn't.
Three years later, now a teaching assistant and graduate student
in the math department here at the University of Pennsylvania,
I have not forgotten that resolution. My guiding philosophy in
my teaching stems from that moment: teach students to be teachers.
Rather than stand up in front of them and lecture, which I know
will oftentimes at 8:30am go in one ear and out the other, I regularly
give the students problem sets that they first work on in small
groups and then explain in front of the rest of the class. During
their explanations, I encourage them to elaborate on certain points,
trying to help foster their ability to communicate their ideas
lucidly. Students are sometimes shy about this at first, but these
interpersonal skills are so crucial, and it is extremely rewarding
to see them progress in that regard over the course of a semester.
Also, by getting these extra opportunities in which they really
have to think deeply about the material in order to explain it
to someone else, students gain a better grasp of the subject material
themselves. Another benefit of conducting recitation in this fashion
is that frequently two students will propose different ways of
approaching a problem, both correct, so that students are more
likely to be exposed to a method that makes sense to them than
they would if they just saw my way. In my two years of being a
teaching assistant here, I have observed that students really
listen to each other when they get up in front of the classroom
to speak, probably much more so than with a professor. Being able
to not only teach students a subject that I love but also to help
them develop their own ability to be teachers is an absolutely
joy. I believe my pedagogical philosophy of teaching students
in technical fields to be teachers themselves will help them become
leaders in industry and maybe even open up their eyes to the option
of being teachers in some venue themselves.
