Teaching
Philosophy
David Orr (1994),
in his provocative and insightful book entitled Earth in
Mind: On Education, Environment and the Human Prospect, dispels
the notion that all education is good, and that more of any kind of
education
is better. His words, and the words of
Elie Weisel, whom he quotes, speak candidly about the past failures of
liberal
education to provide our youth with the kind of education that will be
needed
to live wisely, and with consideration for other life forms that
sustain us and
those who will follow. Orr argues:
The truth is that many things upon which our
future health and prosperity depend are in dire jeopardy: climate
stability,
the resilience and productivity of natural systems, the beauty of the
natural
world, and biological diversity. It is
worth noting that this is not the work of ignorant people.
Rather, it is largely the result of work by
people with BAs, BSs, LLBs, MBAs and PhDs.
Elie Wiesel once made the same point noting that the designers
and
perpetrators of…the holocaust – were the heirs of Kant and Goethe,
widely
thought to be the best educated people on earth. But
their education did not serve as an
adequate barrier to barbarity. What was
wrong with their education? In Weisel’s
words,
‘It emphasized theories
instead of values, concepts rather than human beings, abstraction
rather than
consciousness, answers instead of questions, ideology and efficiency
rather
than conscience.’
I
believe the same can be said of our education.
Towards the natural world it too emphasizes theories, not
values;
abstractions rather than consciousness, neat answers instead of
questions; and
technical efficiency over conscience…The worth of education must now be
measured
against the standards of decency and human survival – the issues now
loom so
large before us in the twenty-first century. (pp.

Although I teach a
variety of courses that have different goals, my teaching philosophy is
largely
guided by Orr’s words along with one other important tenet: Teaching
is much more than disseminating knowledge; rather it requires
orchestrating an environment which fosters engagement, questioning,
exploration, discussion and application of ideas. Research in cognitive
science (how we learn)
teaches us that humans are active constructors of knowledge. Meaning-making is a process of
constructing new conceptions of the world which are informed by both
present
and past learning experiences, and prior conceptions/misconceptions. Orchestrating an effective learning
environment therefore requires that students
continually explore, elaborate on,
challenge, and assess their understanding.
Moreover, it requires an awareness of the diverse
ways in which people learn and therefore the variety of teaching
methods which can
be used to cater to diverse learning styles. In
short, effective teaching requires a
consideration for both the “what” and “how” of learning.
Although
lectures can serve an
important purpose, courses that are taught solely in this way send
clear, albeit
unspoken, messages about the nature of knowledge and learning. Among the most significant of these is that
learning is a passive process of disseminating knowledge akin to
pouring water
into a bucket, rather than an active, exploratory, and co-constructive
dialog between teacher and pupil. To
meet these challenges I use the following
principles to guide learning
- First engage by anchoring
learning to a
social/environmental/technological
issues or contemporary scientific questions which provoke interest and
have personal
relevance and meaning for the student.
- Orchestrate an authentic learning environment
by
involving students in scientific discourse in the context of important
biological questions/observations, or societal/health/environmental
issues so that students clearly
understand
that the purpose of learning is more than to simply do well on exams;
rather it is to help us understand the natural world and live wisely in
it.
- Structure
"hands-on and minds-on" learning environments in which students
are utilizing a variety of senses to observe, explore, manipulate, and
test their understanding of the natural world.
- Stimulate critical thinking and create autonomous
learners by structuring a
learning environment in
which students ask important questions, frame problems, reveal and
challenge current
conceptions and worldviews; identify knowledge that is
lacking; and probe for deeper understanding
using
learning resources beyond the instructor/textbook.
- Emphasize the process of scientific
investigation to help
students understand the power and limitations that science has to
reveal the
workings of the natural world, the continually changing nature of this
knowledge, and how the scientific community operates to reach consensus
on the validity of this knowledge.
- Make learning interdisciplinary by encouraging
students to consider
science-related technological, political, social, historical, or
ethical/moral
ideas in resolving socioscientific issues.
- Engender a collaborative dialog between student and
teacher about the synthesis, application,
and evaluation of knowledge to provide on-going and timely
feedback
to both the student and the instructor on what has been learned.
- Emphasize the acquisition of
a diversity of interpersonal communication skills by
allowing students to communicate their ideas formally and informally
through a variety of different media
(scientific research articles,
reports, proposals, editorials, letters, formal presentations, debates,
informal class
discussions).
Most of my courses are inquiry-based and employ Problem/Case
Studies Based Learning (PBL/CSBL) methods to
meet these challenges. To find out more
