In chemistry courses for non-science majors, it is common practice to assign a paper. Papers encourage students to learn on their own and are very instructive if the topics are chosen carefully. An assignment I have used for a number of years seems to work well and is based on the weekly news magazine of the American Chemical Society, Chemical & Engineering News (C&EN). ACS members who read C&EN regularly know that each issue contains a wealth of information of importance to the chemical profession and often features an in-depth report on a topic of pure or applied chemistry that is accessible to nonspecialists. Nearly every issue reports, briefly or sometimes in depth, on
some aspect of environmental chemistry, for example. This is pertinent to the course for nonscience majors, Perspectives in Environmental Chemistry, that I teach at Lewis & Clark. Currently, Chemistry in Context (1) serves well as the textbook.
Each issue of C&EN, in effect, provides a snapshot
of the chemical profession for that week. That thought, in
turn, suggests that a student who reads a single issue could
come away with a reasonably accurate basic impression,
admittedly incomplete, of what is going on in the profession as
a whole. Readers of this journal are well aware of the
notion that the compelling reason to teach chemistry to
nonscience majors is not only to expose students to the
beautiful theories and systematics of chemistry but to teach
them what chemistry is all about, and in particular, to show
them the importance of chemistry in the modern world. I
submit that the impact of chemistry on the modern world and
on our society can be found in any issue of
C&EN by a reasonably careful reader. This premise is the basis of the
assignment described below.
The Assignment
Students are required to read a single issue of
C&EN and write an essay on their impression of the chemical
profession based on that issue. They are encouraged to
comment on every part of the magazine, including letters to
the editor and advertisements as well as articles and brief
news items. I hand out a single-page instruction sheet,
available as an online supplement to this article (see Supplement link on this page) or upon request by mail or email:
etw@lclark.edu, in order to
give the students a clear idea of what I expect in the way of
content and style. Our general education requirements
at Lewis & Clark College emphasize the importance of
good writing. In general, our students are not surprised to
be asked to write good prose in a chemistry class, but it
doesn't hurt to remind them that we expect good writing even
so. It is important to emphasize that students should
not merely paraphrase the articles, but rather construct an
image of what chemists do generally and which issues
concern them. Of course, some issues of
C&EN make this task somewhat easier than others, but in my experience, this does
not make a significant difference.
I have found that a paper of some 500 words (23
typed pages) is long enough to allow students to produce
decent essays, but some students tend to exceed that length and
in so doing, often produce better papers. There are so many
articles and news items in a single issue of
C&EN that it can be difficult to do justice to the assignment in a mere
500 words. Since introductory chemistry lecture sections tend
to run large at most colleges, the instructor will also be
mindful of the grading workload. Thus, I would recommend
that the minimum paper length be 500 words, but that strict
adherence to that limit is inappropriate and somewhat
longer papers yield better results. I normally request an essay of
at least 1000 words and students easily comply.
As a member of the ACS, I receive 52 issues of
C&EN each year. I save these and hand out one copy to each
student with the assignment instruction sheet. This makes
the assignment easier for the student, since the reading can
be done at home (C&EN issues cannot be checked out of
libraries). Because each student reads a different issue, this
procedure has the virtue of ensuring variety in the papers
(important for the instructor who must read many of
them!). This also makes it difficult, if not impossible, for
students to plagiarize or use paper-writing services and I have
seen no evidence of such cheating. The students return the
issues with their papers, making it easy for me to see
how well they capture the essence of the issues they read in
their respective papers. Although one would not really argue
that a given issue of C&EN is timeless, issues up to two
years old seem to serve the purpose well. Students appreciate
getting their own issue to keep for a while and have fun
riffling through the pile to pick out one with an
interesting-looking cover.
I ask that students try to connect their own
interests to information in the magazine. For example, business
and economics majors should, and do, find many items
relevant to their studies and are often amazed by the size and
scope of the chemical business. I have also found that by
encouraging a creative approach to the paper, interesting
results obtain. Papers in which students had a bit of fun
employing their creative impulses are also more fun for the
instructor to read.
The Results
A typical student response might start out or end
as follows.
"Upon getting this assignment, I was afraid that
I would be bored and confused by dry technical material
that I could not understand. To my surprise, I found much of
interest and was impressed by aspects of the impact of
chemistry on my life that I had never thought about.
Reading this issue was very interesting and I was amazed to see
how important is the role of the chemical industry in the
U.S. economy. It was also interesting and reassuring to see
(in the Letters Section, for example.) that chemists are
concerned about the environment, the job market for
graduates, and other issues that affect us all. Chemists are
working to develop appropriate technological solutions for
problems ranging from environmental to economic issues in
the developed and developing world.
"My overall impression of the journal is quite
different from what I expected. This journal is not only dealing
with science and scientific problems but also informs the
reader about the interaction between the scientific world,
industry and society in general."
Or, here is a direct quote of the initial paragraph
from a student paper:
"If one compiled a picture of modern society's
perception of 'The Chemist,' it would be a wild-haired
madman with no common sense. When one even begins to
mention that there is a world of completely normal functioning
humans who are chemists, he/she is immediately put off
as being in league with those chemical crazed scientists.
These worlds of the scientists and the world of 'normal' people
are not all that different. The journal Chemical and
Engineering News gives an average person an insight into the life
of the chemists and it is easy to see that the two worlds
are essentially similar to one another. The structure,
content, and style of the magazine shows that the same issues
that are confronting the mainstream of society are also
affecting the chemical world in a similar manner."
What more could a chemistry teacher ask for?
Some of the creative approaches used by my
students will exemplify the "fun" some of them had with the
assignment. Several have written the paper as if it were a
letter to their high school chemistry teacher describing their
experience in college. One wrote it in newsletter format
What's Up With Chemistry? Another wrote the paper in the
format of a talk-radio show discussing chemistry, complete
with commercials straight out of the magazine. A student
who might have been inspired by the movie
Waterworld wrote her paper from the point of view of an archaeologist in
the future who discovered a well-preserved issue of
C&EN in a cave while visiting the planet, which had long since
been submerged due to global warming. The magazine gave
insight into what was going on on the planet 500 years ago.
Thus, I believe that the assignment succeeds in
fulfilling the goals set forth above. I suspect, although I have
not tried it, that this assignment could also be worthwhile
for students in general chemistry courses for chemistry and
science majors. It might leaven the standard diet of
equations, theory, and problem solving and give students a
good glimpse of the world that they would enter as a member
of the profession.
