Fascination with materials and chemical change is a hallmark of
chemists, and it is also an important pedagogical tool.
A fringe benefit of editing
JCE is that I encounter so many nice people who send interesting and helpful
communications. One of the first of these to cross my desk this year was
from E. J. Behrman, who recommended that I read and call to
your attention "Brilliant Light: A Chemical Boyhood" by
Oliver Sacks, noted neurologist and author. It appeared in the
December 20, 1999, issue of The New Yorker and is well
worth your time and effort to find and read. Sacks's reminiscence
of his boyhood interest in chemistry is fascinating. His
obvious love of our science is inspiring. And he has expressed both
in words that are brilliantly chosen and a joy to read.
In a profile of Sacks that appeared in
Chemical and Engineering News (January 10, 2000), Madeleine Jacobs
relates that he is writing a book on his boyhood encounters
with chemistry (to be published by Alfred A. Knopf). I am
looking forward to that with great anticipation. During 1999
he also wrote an article on the periodic table in the
New York Times Magazine (April 18) and an op-ed piece on
chemistry sets in the New York Times (May 13). In the latter he
describes how hard it is these days for a nonchemist,
especially a young one, to obtain chemicals to experiment with.
Chemistry sets are not what they used to be!
Sacks's writings contain important messages for all of
us who teach chemistry and all who are involved in piquing
students' interest in our subject. A brief excerpt from his
New Yorker article illustrates my point.
I knew zinc--the dull, slightly bluish birdbath in the
garden was made of zinc--and tin, from the heavy
tinfoil in which sandwiches were wrapped for a picnic.
My mother showed me that when tin or zinc was bent it
uttered a special "cry." "It's due to deformation of the
crystal structure," she said, forgetting that I was five and
could not understand her--and yet her words made me
want to know more.
Fascination with materials and chemical change is a
hallmark of chemists, and it is also an important pedagogical
tool. Real substances have very interesting properties--ones
that can excite students and spur them to greater
achievement. Sacks's writing is full of such fascinating factoids. It
inspires me to try to use them much more effectively to help
students develop the curiosity and commitment that will
help them learn. Everyday things, such as the startling cold of
a diamond engagement ring when it touches one's lips, can
illustrate otherwise tiresome topics like thermal
conductivity far better than a table of data.
Sacks was fortunate that his parents, both physicians,
had the means and took the time to show him interesting
phenomena and respond to his many questions, as did
two uncles. In addition, his father's office was in their home,
providing a broad range of interesting substances and
solutions that enhanced his curiosity and experience. Few of our
students have had such opportunities before they come to
us, but we can resolve that they should not leave our classes
without seeing and experiencing real chemistry that grabs
their attention and interest.
If we are to do this, we must be familiar with lots
of chemical phenomena and realize how they can be applied
effectively in our classrooms and laboratories. And we need
to know which of them are appropriate for students to
observe and interact with without violating rules of good sense and
chemical safety. That's no mean feat, especially if our
own backgrounds are much less rich than was Sacks's
childhood--an extremely likely possibility. Formal education is
important, but it is unreasonable to expect that it can provide all
the knowledge that would be useful to any of us in our
teaching. And new chemistry is discovered every day. Learning
more and more chemistry and improving our teaching skills are
processes that continually require our attention and effort.
I hope that JCE contributes in important ways to
such professional development. My overriding goal for this
Journal is to provide accurate, interesting, relevant
information that can enhance chemistry teaching and learning. Your
editorial staff organize the information so that access is as
quick and easy as possible, and we try to make connections both
by juxtaposition of articles in print and by linking
information electronically. The latest example of this is being
introduced this month. It is a new feature directed especially to busy
high school chemistry teachers: the JCE High School
Chemed Learning Information Center (JCE HS CLIC). In this
special section of JCE Online we have collected and
organized JCE's many articles that are of interest to high school
teachers, aiming to provide the quickest, easiest access to the
information. You can read more about it on page 536. We
look forward to feedback from those who have tried CLIC and
have suggestions for adding to it or otherwise improving it.
When asked how children today could be weaned
from the many distractions of modern life and turned on to
chemistry, Oliver Sacks recommended, "Enthusiastic teachers,
vivid experiments". I recommend that you read Sacks's article
in the New Yorker to rejuvenate your enthusiasm and read
JCE to find new, vivid experiments. The combination may be
just what is needed to capture students' attention for the rest
of this school year and to enhance learning for many years
to come.
