Delphi Studies & Unifying Themes in Chemistry |
![]() |
Concept inventories assess the common misconceptions and
alternative conceptions of students with regard to key concepts in a given
subject area. Educators who are equipped with these concept inventories can
communicate the main ideas of a course much more effectively by specifically
addressing known student misunderstandings. Because effective concept
inventories will focus on the most important concepts of a particular subject
area, it is important to begin such research by identifying those ideas which
are most important to the field.
In order to ensure that we develop effective concept inventories in chemistry,
we are conducting a Delphi study of experts that will generate a list of
unifying themes in chemistry. We are looking for those concepts which play a
fundamental role in many or all of the various divisions of chemistry: organic,
inorganic, physical, analytical, and biochemistry. Experts were solicited from
each of the traditional chemical divisions, as well as from among community
college and high school teachers. Philosophers and historians of chemistry are
also represented on our panel of experts. The iterative nature of the Delphi
survey technique allows the experts to reach group consensus as to a list of
unifying themes that illustrate the relationships among key concepts in
chemistry.
We intend to use these unifying themes as the framework for concept inventories
in all divisions of chemistry. We believe that by structuring concept
inventories (and, consequently, curriculum development) around unifying themes
in chemistry, the relationships between the various divisions will be made
explicit. In this way, we hope to facilitate transition between disciplines and
increase student understanding of the vast field of knowledge that spans the
many divisions of chemistry.
