The number of students entering post-secondary education is increasing, so
in turn more students are making the transition from high school to college. This
transition requires that high school and college teachers communicate about curriculum
and pedagogy. Many of the latest initiatives by NSF are predicated upon the assumption
that these partnerships will be formed. One way to improve such communication
and to find points-of-contact within the subject matter is through this Journal,
which provides articles about both high school and college courses and serves
to illustrate examples of today's best practices. This issue, for example, furnishes
much evidence that the study of biochemistry and the applications of chemistry
to biology are increasingly important at the college level. One of the many goals
we set for ourselves and our students is to make matriculation as smooth as possible.
Did you know that some universities are offering an integrated organic-biochemistry
course to entering freshmen (1)? Reasons cited for
the break from the norm are that students inherently find the applications of
chemistry more interesting and this hook may attract more potential majors, plus
it places what is now second-semester general chemistry closer to the study of
physical chemistry (a more natural continuum.) Reported in the NSF
Highlights is a program that offers a biochemistry option within the General
Chemistry Track at Kennesaw State University. The authors report on several interfaces
between their respective chemistry and biology programs, and within this program
a large emphasis is being placed on needed tools/techniques (such as UV-vis spectroscopy,
electrophoresis, and PCR). A particularly interesting article this month is in
the Chemistry for Everyone section. Zovinka and Sunseri
discuss the topic of photochemotherapy and the ability of this treatment to fight
disease using UV, visible, or near-IR light with the administration of a photosensitizer.
We live in a world that is more and more dependent upon the biological applications
of chemistry and that has a substantial emphasis on laboratory techniques. Many
of the selections in this month's In the Laboratory section also center on biological
and biochemical applications: triboluminescence, analysis
of Brazil nuts for selenium, identification of yeast
mutants, enzyme chemistry integrated into a first-year
biochemistry/chemistry course, and synthesis of various organic compounds
by advanced undergraduates (Synthesis of 4-Methylumbellifer-7-yl-α-D-Mannopyranoside
and Synthesis and Spectral and Thermal Properties of Pyrazine-bridged
Coordination Polymers of Copper(II) Nitrate). In order to properly prepare
our students, we must consider what academic background is needed: appropriately
sequenced curriculum and employable laboratory skills.
The National Science Education Standards (NSES) serve to address some
of these issues. According to Lowery Bretz, the NSES
are having a "profound effect on curriculum development, assessment of student
learning, and pre-service teacher education". She reports on an innovative degree
program for high school teachers at Youngstown State University. It integrates
learning content with appropriate teaching practice, creating "pedagogical content
knowledge." There is also an extensive reading list that instructors of pre-service
teachers and chemistry education researchers will find valuable.
The JCE Classroom Activity for this month, Through
the Looking Glass, complements National Chemistry Week's activities (2)
on how chemistry affects our world by allowing us to lead cleaner lives. Bringing
practical applications for the study of chemistry into the classroom is one of
the best ways to orient your students to the applicability of chemistry and engage
them in the wonders of experimenting. This particular activity lends itself nicely
to open-ended investigations and is designed so that students will have to employ
combinatorial logical-thinking skills.
Students' interest can also be engaged by research projects. Schildcrout
recommends the introduction of research methodology to undergraduates in a one-hour
capstone course. What basic skills do our students need to begin independent research?
The Journal is probably your best resource to answer this question. Chemistry
Comes Alive!, Volume 6 is here! This latest addition to the JCE CD-ROM
family contains more than 600 QuickTime movies and more than 3600 still images
illustrating laboratory procedures and techniques. The laboratory skills found
in this volume can be used for pre-laboratory instruction and you can also incorporate
the clips into your own multimedia presentations.
High school science courses provide the foundation that our students will take
with them to college. Take time to think about what knowledge and skills your
students will need for the next step. Science is a way of thinking in which prior
knowledge determines the logical connections that will be laid down in one's future.
Understanding science will be easier when the proper building blocks with a large
number of "points of integration" (3, p 21)
among the subjects are presented to our students.
