Teaching
science: Enthusiasm, hands-on experience make Honolulu school a paradise |
There is a lot of hand-wringing about
science education in U.S. schools, but not in the classrooms of Iolani
School in Honolulu. There the students are eager to learn and teacher
and science department chair Frederick Heyler (BAS 1988 CEE, MS 1989
CEE) is happy to teach. About two in five of Hawaii’s National
Merit semifinalists come from the independent school, which supplements
teaching science theory with ample hands-on lab and project experiences.
Heyler’s enthusiasm for teaching is sustained by the commitment of
his students but was kindled partly by the outstanding teaching he saw in
Stanford’s civil and environmental engineering department. The lectures
and labs he took at Stanford remain fond memories as he teaches science to
new generations.

In the decade
you’ve been teaching, has the attitude of students toward
science and math changed much? |
| |
The interest in science has
increased: both the pressure from parents for their children to have
the opportunity to take more science classes, as well as a desire from
the students to take more science classes has grown.
Many universities like to see more science during their applicants'
high school years. Some of the state universities have increased their
requirements for the requisite number of science courses for admission.
Additionally, I think there is an increasing desire by parents for their
kids to be technically literate, something that they see as a key to
vocational success in the future. Many of our parents desire careers
in engineering or medicine for their children.
Our students tend to be bright and very well-motivated. Almost all take
at least three years of science —biology, chemistry, and physics.
About half of our students take a fourth year, Advanced Placement, science
course. Approximately
one third of the students reach calculus in their senior year with the
remaining two thirds ready for calculus when they enter college. |
 |
It must be great to
have motivated kids. |
| |
That’s what’s makes
teaching so rewarding—the incredible motivation of these kids.
They want to do well and are willing to work very hard to achieve excellence.
A large number of them have a desire to pursue careers in engineering or
medicine. |
 |
Of course engineering is not taught
at the high school level, typically. Does it find its way into science
classes? |
| |
There are the three basic science classes: biology, chemistry and
physics. We offer different levels of first year chemistry and physics,
including AP Physics. After that there is the option of a fourth year
in science, whether it be Advanced Placement (AP) Biology, AP Chemistry
or AP Physics. Many students who have an interest in engineering express
a desire to take the second AP Physics course—since engineering typically
involves the application of physics principles.
Of Iolani's four physics teachers, two have PhDs in physics and two of us
were trained as engineers. Those of us trained as engineers tend to take
a more practical bent towards practical applications of physics concepts. |
 |
What do the kids respond to most in
the classroom? |
| |
What they often respond to the best is where the concept is introduced
and then they have to work with it in the form of a laboratory. For instance,
today I am introducing the theory of electrical resistance and resistivity
using a Power Point presentation, demonstrations, and analogies with
water flow. Following this, students will do a laboratory where they
design an actual circuit and incorporate ammeters and voltmeters. They
will then use their results to calculate the resistivity of both Play-Doh
and the graphite in pencil leads. The students must think and apply the
material just learned using common every-day objects. They are generally
impressed with the accuracy of their results.
In our regular physics class we’ll do about 50 labs and in the AP
Physics class we’ll do about 60 labs. We are fortunate in that our
Physics classes meet seven class periods per week (rather than the typical
five for other subjects), allowing the additional time for in-depth laboratories. |
 |
It sounds like you offer a lot of hands
on experience for students. |
| |
It helps greatly with their retention of the material to actually
work through and apply concepts in the laboratory. Additionally, the
Advanced Placement Physics exams will typically incorporate one to two
questions that directly relate to hands-on laboratories.
|
 |
Does this hands on approach occur in
other science classes? |
| |
Although Iolani enrolls students from Kindergarten, our Upper School
division has students from 7th grade to 12th grade. We have a 7th grade
Earth Sciences class and an 8th grade Physical Science course prior to
students beginning the high school sequence of Biology, Chemistry, and
Physics. Other faculty members share the philosophy of first introducing
scientific theory with academic rigor and then giving students the opportunity
to apply that theory in laboratories. Altogether, there are 19 full-time
faculty members in Iolani's Upper School Science Department. |
 |
When you talk to other teachers, do
you find there is a similar rise in interest in science? |
| |
Hawaii has the highest percentage of students in private schools of
any state in the nation with approximately one quarter of the students
enrolled in private schools. Conversations with teachers at other independent
schools in Honolulu, indicate that they too have seen student interest
in science increase. The four largest private schools in Honolulu have
made substantial investments to improve their science educational facilities.
Each of the three other large independent schools in Honolulu has built
a new science complex within the last decade. Four years ago, Iolani
substantially expanded and completely renovated the physics, 7th grade
earth science, and 8th grade physical science laboratories and classrooms.
Additionally, our AP Biology program has received a dedicated suite with
office, laboratory, and lecture room.

At Stanford you majored in civil engineering.
How did you eventually become a teacher? |
| |
I came to Stanford thinking I wanted to major in physics. But then
when I actually experienced civil engineering and hydraulics —the
very nature of things you could see, feel, touch, apply —it fascinated
me. I decided to major in civil engineering and concentrate in hydraulics.
In the back of my mind I had always thought I would teach on the university
level, but after my Masters degree I decided to spend a couple of years
working before making the investment in a doctoral program lasting several
years. I was thinking I’d better make sure I knew what I wanted
to study. So I went to work for Bechtel in their hydraulics research
group for five years. I enjoyed the work and never got around to going
back to school.
Meanwhile while living in San Francisco, I met my wife who was from Hawaii
but who had attended UC Santa Cruz. We moved back to Hawaii and I worked
for a local engineering consultancy here for 3 years. My latent desire
to teach became rekindled during this time. My wife is an Iolani alumna
and she maintained contact with some of her former teachers, one of whom
is also Iolani's senior physics teacher. In a conversation, he noted that
there was an opening teaching physics. Remarkably, they hired me and I
figured I’d try teaching for a few years to see how I liked it and
whether I should get a PhD to teach on the college level. After a few years
I began to realize that I greatly enjoyed teaching high school physics
at Iolani. I am in my tenth year of teaching now. |
 |
What do you like so much about teaching? |
| |
The resources here, the support, and the students are all outstanding.
In some ways the material is comparatively basic but the challenge becomes
figuring out ways to effectively communicate it to students in the form
that they will grasp.
It is a wonderful experience to see the proverbial light come on in students’ eyes
as they actually understand the physical world around them. For instance many
will show amazement when they grasp the underlying theory of how modern
electrical power systems work, why the sky is blue, how rainbows form,
and why a car has less acceleration the faster it travels. |
 |
What projects are the most fun? |
| |
Some of the mechanics projects. In some years our regular physics
classes build mousetrap cars. After racing them, they use a few simple
distance and time measurements to determine the acceleration, accelerating
forces, retarding forces, energy of forward motion, rotational energy
of the wheels, etc. They also assess the net efficiency based on total output energy versus input energy. It is rewarding for them
to actually build the cars, to see them work, and to apply concepts learned.
It’s both good-natured fun and a wonderful review of the concepts
of mechanics—how and why objects move.

When you look back on Stanford, what
do you think had lasting value in your career? |
| |
The teaching at Stanford was outstanding, particularly in civil engineering.
Indeed, the fun, interesting classes taught by outstanding, committed
professors attracted me to major in civil engineering. I had many outstanding
teachers including Jeff Kosseff, Anne Kiremidjian, James Gere, and Ronaldo
Borja, to name just a few. Additionally in many civil engineering courses,
labs provided a practical application of what was being learned in class.
I am grateful for my Stanford education both in terms of the fundamental
grasp of the concepts that I obtained and the fun, interesting, rewarding
manner in which they were taught.
