In the May issue of this Journal, Scerri commented that one of the
problems with chemical education research is that we have strayed too
far from our roots and failed to “engage in issues of chemical
content” (1). I would like to
counter this with some of the articles that are printed in this issue.
The extent of instrumentation
use in undergraduate chemistry courses has increased considerably over
the years. Malina and Nakhleh
are very engaged with evaluating students’ use of instrumentation
and students’ understanding of the concepts studied. Today’s
students are exposed to many more types of instruments than were those
of previous generations. However, the theoretical framework that affects
learning at this level is only just beginning to be developed and is
an excellent chemical education research area to pursue. In my opinion
preparing students to be chemists centers on their ability to use and
understand “modern” instrumentation. I know that my experience
with instrumentation was very limited—I was in graduate school
before I touched anything beyond a microscope. Today, more and more students
are expected to understand the technology that is at hand. Our job therefore
is to identify what foundation needs to be laid at the secondary level
so that our students will be prepared for success in this world.
According to Boschmann, “Chemists have a
long history of using technology for teaching and learning”, and
it is well established that students learn better when they are actively
engaged in the subject matter. I know that many teachers currently use probeware in many of
their classroom activities. While probe use appears to be more popular
at the secondary school level than in the colleges, we need to know more
about its value and future effectiveness. The ability to take data much
faster and more accurately are two advantages noted by students for why
they like using the updated instrumentation.
Computer-based probes and a programmable
image acquisition system are also
mentioned in this issue of the Journal. In the article by Ogren,
Henry, Fletcher, and Kelly, examples of how to use LabVIEW
computer stations are given. Teaching chemistry via distance education
has always been
a problem when it came to having students perform labs. The Boschmann
article addresses how some of these concerns are being met
using currently available technology. If you are considering teaching
a beginning
chemistry course via the Web, you might want to purchase the 7th edition
of the JCE General
Chemistry Collection. New in the edition are
pH titration simulator and two programs very appropriate for high school
students, Inorganic Nomenclature and Writing Electron Dot Structures.
Other
interesting reports that you can find in this issue are the reflections
by Mary Harris on receiving a presidential
award for Secondary Science Teaching. Many of you qualify—or know
of someone who qualifies—for
a presidential award. According to Mary these awards will no longer be
given every year as they have been. It’s too late for the secondary
award applications for 2003, so you have over a year to consider your
submissions for the next secondary award that will be given in 2005.
A
commentary by Holme calls for interested
volunteers to contact him to
help write new questions for the ACS DivCHED
exams. Writing good multiple choice questions for an ACS exam takes real
skill and hard work. Holme’s article describes the process of writing,
selecting, and validating the questions that are chosen for the final
version of each exam. Getting involved in writing exams at the national
level is an excellent choice to further your career, so you might want
to consider Holme’s request.
It soon will be summertime so don’t
forget to check out the summer reading suggestions.
The reviewers have suggested a variety of
choices. Coppola recommends that books
that go beyond chemistry or even science be in clear view to our students.
If some books on your
shelves reflect your personal choice, this may lead to insightful conversations
with students. Don’t forget to check out the Web sites in News
& Announcements to get the updates on local, state, regional, national,
and international meetings on target for this summer. See you in July
at
ChemEd 03 in Auburn!
