University faculty think of their institutions as places
in which learning is valued and pride themselves on the
discovery of new knowledge. Indeed universities have been
unusually successful in supporting research and developing
new knowledge that has been enormously beneficial to society,
and university faculty value learning far more than the
average. But some kinds of learning are more valued than
others-a fact that I believe is detrimental to the long-term welfare
of both universities and society.
By far the most valued learning is by someone who
discovers what nobody else has learned before. We call the
process of achieving such learning "research". It is the coin
of the academic realm, at least partly because it is easy to
evaluate. Those who do it creatively can reap the rewards of
respect from their colleagues, better facilities and
instrumentation from their institutions, regional and national
awards from their disciplinary societies, and increased funding
from government and industry for their endeavors.
Significantly less valued are activities that help others
to learn, especially when the learning involves things
already known by many. We call such activities "teaching",
although the dictionary definition of "teach" ("to show how to do
something; give instructions to; train") is not broad enough to
encompass the range of activities currently being used to
encourage learning.
There is a widespread notion that teaching is easy
and requires no real creativity. Nontenured faculty are
often warned that time spent on teaching will be thought of
as "wasted", and those well established in research have
been criticized for spending too much of their time on the
"unproductive" activity of teaching. Teaching is held out to
students as a fall-back position in case their other career
plans do not pan out, and sometimes those who educate
teachers are willing to accept less than the highest quality from
the students to whom they provide credentials. Those who
employ teachers often require little or no evidence that a
candidate is prepared appropriately. At the college level,
evaluation of a lecture on research is considered adequate, with
the tacit assumption that someone who knows a subject can
teach it-or worse, that teaching ability is irrelevant. At the
pre-college level, the attention paid to subject-matter expertise
is often minimal, the assumption being that someone
who knows how to teach can do so without knowing what
students ought to be learning.
Helping students to learn is an activity that has
long-term value to society, but our society seems bent on
discounting the future. Research can do things for us now (or
soon). Teaching nurtures potential research workers, helps
citizens understand better the choices they need to make
regarding society's future directions, enables students to connect
what are now separate disciplines into new areas of intellectual
development, and develops intellectual abilities that
otherwise might be lost. These benefits will perhaps not even
accrue within some of our lifetimes, so why put resources into
them now? We can profit more now if we avoid taking
responsibility for the future-and often we elect to do so.
In a world increasingly dependent on
intellectual rather than economic capital, such a course
seems bound for disaster. But can we do something about
it? One way to improve the status of teaching would
be to make it easier to evaluate how good a job a teacher has
done-to greatly improve our ability to assess accurately
whether students have met the learning goals we set for our courses. The inability of
current assessments to demonstrate that students have
learned what we want them to makes evaluation of teaching
subjective and superficial. Performance of students on most
current assessments is relatively independent of both teacher
and method of instruction, but more sensitive tools could
distinguish those who understand more deeply from those
who do not. Better assessment would bring to the discipline
of chemical education more credence and respect.
To a considerable degree, assessment of students
drives how students react to our curricula. If we want students
to develop their abilities to address and solve problems
different from those they have seen before, then we need to
develop means of assessing whether they can do so. Such means
might be pencil-and-paper tests or quizzes,
technology-mediated problem-solving simulations, or observations of students'
contributions to a group solution of a difficult problem.
There would be far more concern about students' mastery of
chemistry if those students had to perform in assessments that
really measure deeper knowledge and understanding. The
need is to find new assessment methods that can be applied by
large numbers of faculty and that are much more effective in
finding out whether our learning goals have been met.
A start along these lines has been made in the
Conceptual Questions and Challenge Problems column in
JCE Internet
(http://jchemed.chem.wisc.edu/JCEWWW/Resources/CQandChP/
). Edited by William R. Robinson and Susan C. Nurrenbern, the site awaits your contributions of
additional questions that can assess students' conceptual
understanding. These should complement the many questions in current
examinations and textbooks that are designed to assess
whether students can apply algorithms to the solution of
common chemistry problems. This column and other similar
efforts represent initial steps in the direction I think we need to
be goingtoward much more effective ways to demonstrate
that students have, or have not, met our learning goals. Such
demonstrations can in turn provide a much better foundation
for evaluation of teaching, thereby enhancing the status of
good teachers and good teaching. Eventually they can lead
to greater recognition of teaching's importance to our
discipline and our institutions of learning.
