The Department
of Physics and Astronomy currently has several research programs which
are open to student involvement at all levels. If you are interested in
participating, feel free to contact the faculty members involved for more
information.
Astronomy:
The current
astronomical research programs at UW Oshkosh are centered on stellar spectroscopy and photometry. Both are used to gather abundance and population data from both cluster and field stars, which
serve as probes of the fossil record of galaxy formation. Many important
questions
remain unanswered about the chemical and dynamical history of our Milky
Way galaxy, and the processes which shape its present characteristics.
A detailed
knowledge of the properties fo the stellar populations
throughout the galactic disk, halo, and globular clusters can place
significant constraints on many of the possibilities. With recent
improvements
in detector technology, theoretical models, and large aperture telescopes,
we may finally be in a position to address these issues.
There are several research projects which
are either ongoing or in the planning stage, most of which have openings
for student
contributions.

Computer Instrumentation:
Undergraduates in the computer and
instrumentation emphasis are working on computer-interfaced equipment
for data acquisition and experiment control. Included are a
system in which operator eye motion is monitored by video cameras
and controls robot arm motion (John Floyd), digital filtering
of frequency multiplexed signals (Gary Zehms), and computer
interfacing of a gas chromatograph for use in high school science
laboratories (Don Macaulay).

Magnetic Resonance:
Nuclear
magnetic resonance (nmr) and electron paramagnetic resonance (epr)
are used to study molecular motion and structural changes in
non-metallic solids. Materials under study include ferroelectric
and ferroelastic materials, plastic crystals, and superionic
protonic conductors.

Physics:
Currently,
this research centers around an off-campus collaboration with Hartmut
Höchst at the University of Wisconsin's Synchrotron
Radiation Center. Right now, we are interested in geometric, thin-film
effects that are predicted to modify the magnetic circular dichroism
signals from ferromagnetic materials. If you find that tantalizing and
want to know more check out Hartmut's tutorials.

Physics Education Research:
The physics education
research group at UW Oshkosh seeks a deeper understanding
of how students learn introductory topics in physics. Currently,
we are engaged in a series of systematic studies to identify
mechanisms or “triggers” for learning the Newtonian
force concept. These studies are leading us
in two directions: (1) a critical re-examination
of the history of mechanics, especially ancient Greek,
Islamic, and French-Renaissance texts, and (2) the development
of a novel description (“model”) of cognitive
processes necessary for understanding Newtonian mechanics. Certain
aspects of this model are being studied empirically in
UW Oshkosh classrooms. Modern student reasoning is
used to clarify interpretations of the historical literature,
and vice versa. This approach extends studies by
Jean Piaget (1893-1980) on the relation between psychogenesis
and the history of science (published almost a decade after
his death!) Recent advances in classroom technology
allow us to pose and answer many new research questions
in this area.
The Physics Education Group meets once
per week and is welcome to all interested students. Contact: Mark
