for my first teaching job,
at a high school, Ernie Wutzke, the
Principal, took me to visit the room of
Art, the biology teacher I would replace
if I got the job. He said it was impossible
to predict what would happen in
Art’s classroom, and made it
clear he thought that a
very good thing.
When we entered
the room, three students were
at the blackboard arguing about details
of photosynthesis or DNA and the rest of
the class was fully engaged in the discussion.
Art was on his back, on a high workbench
along the window, a book for a pillow,
Ernie and I
stood at the back of the room
while the argument raged, with
no sign of life from Art.
After a while
the discussion took a turn,
as arguments tend to do, toward
the personal. “That’s stupid!”, a student
exclaimed, others responded in kind, and
it escalated. After letting it go for a while,
Art stretched, rolled slowly and silently,
but theatrically, onto his side on the bench,
propped up his sleepy head with his fore-
arm, and everyone in the room stopped
and looked at him, listening but
not yet hearing anything.
They knew what he was going to say!
seemed like forever,
Art commented that while
at the beginning of the discussion
everyone had been listening carefully to
everyone else and learning from it, he didn’t
think anyone was listening anymore. “You might
learn more if you listened to each other instead of
trying to prove how much you know”, and he
rolled back into his napping position,
went back to sleep, and the

He said Art
was the best teacher he’d
ever known, but in all the time he’d
worked there, Ernie had never once
actually caught him teaching.
More than any of the
other teachers he’d known, Art
tried new things, some of which
flopped badly and he
you’re a tenth as
good as he is“, Ernie said,

for the last 56 years he’s been a
hero of mine and an influential mentor.
During those few minutes in Art’s class-
room, I learned one of the most valuable
lessons of my entire teaching career:
The less I teach them, the
more they learn.
Teaching in the
same room the next fall, I
saw how difficult it was to keep
my mouth shut and allow students
to explore ideas on their own
without my needing to
profess to them.
realized that it was easier to keep
my mouth shut when my hands were busy,
so I carved small sculptures in chalk in class
with my pocket knife. At the end of class as
I congratulated them on a job well done,
I presented tiny sculptures to students
who had contributed significantly
that day, and taxpayers footed
the bill for the artwork.
After a month or
so of my doing this, carving
had become much more than a cheap trick
to help me keep my mouth shut. It was a symbol,
a signal, a trigger, a ritual, and an important
component of our classroom culture that
grew more effective the more
we practiced it
students practiced talking
with each other and the more I
practiced staying out of their way,
the more they learned, the more
I learned, and the more
we all enjoyed the
As if by magic,
the simple act of taking out
my knife, beginning to carve, and
keeping my mouth shut impelled
students to discuss things

Later, at the
university level, I peeled the skins
of fruits and vegetables slowly and contemplatively
with my pocket knife as students filed into class. Listening
carefully to relaxed conversation as students came
in and speaking mainly in response to direct invi-
tation, I slowly nibbled on peels until it
was time to get to work.

students in 1969. Triggered often by my choice
of fare for the day, sessions began with a short
discussion of the skins of things. You can
imagine the variety of examples
available. It’s huge.

some of those discussions were
hilarious, depending on little more
than what I happened to be peeling
that day and whatever students had
to say about it. It loosened us up
for the work we were there
to do together.
in high school teaching,
I sketched students in notebooks
and gave them what I’d drawn. I exam-

By a similar
token, meetings with obsessive

they could anyway, so walking while
talking helped them listen.

When Maria Klawe
became Vice President at UBC,
we discovered she did something similar
to my sanding and chalk-carving “thing” in
meetings and classes. Maria painted water-

meetings and meetings with ‘suits’ downtown.
Now, as President of Harvey Mudd College,
renowned mathematician and computer
scientist, she still does. In two wonder-

When Gary Poole came
to UBC to direct our Teaching
and Learning Centre, he and I talked a
lot about our dreams for the future and how
to collaborate to make them real. We usually
did this practically at a dead run. Across
campus, down the road to English Bay,
along the beach trail and part way
back, up the cliff on a steep
trail, and back to our
offices for the rest
of the day.
If either of us
had something hot and
burning to say on the way up
the cliff but couldn’t say it for lack of
air, we stopped as briefly as possible
to get us going again, still out of
breath but able to speak
others about those meetings,
Gary referred to my style of communicating,
punningly, as “running meetings”. I think he was
daring them to meet with me, and many of them
took him up on it. It was great exercise while
it lasted. Now I get exercise
in other ways.

Luis Sobrino’s response when I asked
him in Science One class one day

Luis said ‘On the bicycle.’
When I grilled him
further about it, he told us about
his daily ride from home on a boat in False
Creek, through Jericho Beach and Spanish Banks
parks to the bottom of the hill up to UBC. It’s the same
hill as before, but more gently on a road and sidewalk
instead of a steep trail and biking instead of huffing
up a trail, less than a kilometer from where
had our own epiphanies.
