Student understanding of biological representations has not been well studied. Yet, we know that to be efficient problem solvers in evolutionary biology and systematics, college students must develop expertise in thinking with a particular type of representation, phylogenetic trees. The purpose of this study was to understand how undergraduates…

This paper reports on an investigation of two inter-related but different matters, one of interest to science education researchers and teachers in general, and the other to those teaching about evolution. The first was motivated by the dilemma facing teachers who want to diagnose learners' prior knowledge before teaching and are concerned about…

Analogies play significant roles in communication as well as in problem solving and model building in science domains. Analogies have also been incorporated into several different instructional strategies--most notably in science domains where the concepts and principles to be learned are abstract or complex. Although several instructional models…

College students often come to the study of evolutionary biology with many misconceptions of how the processes of natural selection and speciation occur. How to relinquish these misconceptions with learners is a question that many educators face in introductory biology courses. Constructivism as a theoretical framework has become an accepted and…

Pseudoscience is error, substantive or methodological, parading as science. Obvious examples are parapsychology, "intelligent design," and homeopathy. Psychoanalysis and pop evolutionary psychology are less obvious, yet no less flawed in both method and doctrine. The fact that science can be faked to the point of deceiving science lovers suggests…

Genes are often described by biologists using metaphors derived from computational science: they are thought of as carriers of information, as being the equivalent of "blueprints" for the construction of organisms. Likewise, cells are often characterized as "factories" and organisms themselves become analogous to machines. Accordingly, when the…

Originally designed for K-12 teachers, the Understanding Evolution (UE) Web site ("www.understandingevolution.org") is a one-stop shop for all of a teacher's evolution education needs, with lesson plans, teaching tips, lists of common evolution misconceptions, and much more. However, during the past five years, the UE project team learned that…

The theory of evolution by natural selection has revolutionized the biological sciences yet remains confusing and controversial to the public at large. This study explored how a particular segment of the public--visitors to a natural history museum--reason about evolution in the context of an interactive cladogram, or evolutionary tree. The…

This study investigated the relations among preservice elementary teachers' ideas about evolution, their understanding of basic science concepts and college science coursework. Forty-two percent of 240 participants did not accept the theory of human evolution, but held inconsistent ideas about related topics, such as co-existence of humans and…

Creationists are becoming more active in Europe. We expect that European biology teachers will be more frequently challenged by students who introduce creationist misconceptions of evolutionary theory into the classroom. Moreover, research suggests that not all teachers are equally prepared to deal with them. To make biology teachers aware of what…

Evolution curricula are replete with information about Darwin's theory of evolution as well as microevolutionary mechanisms underlying this process of change. However, other fundamental facets of evolutionary theory, particularly those related to macroevolution are often missing. One crucial idea typically overlooked is that of most recent common…

Comments on the critiques of Tryon (2009a, this issue) and Cunningham (2009, this issue). These critiques provide an interesting contrast: one favoring greater reductionism and one favoring less. I consider each in turn. Tryon (2009a) again has addressed the issue of mechanisms in these pages (cf. Tryon, 2009b). The concepts of function and…

Biological evolution still lacks representation in school, especially below high school level. In order to find new implications that could help achieve significant improvement in teaching evolution, twelve expert interviews with both renowned researchers and experienced science teachers were conducted. Results of the comparison between the…

New science standards and reform recommendations spanning grades K--16 focus on a limited set of key scientific concepts from each discipline that all students should know. They also emphasize the integration of these concepts with science practices so that students learn not only the "what" of science but also the "how" and…

Even 150 years after Charles Darwin published "On the Origin of Species," public school teachers still find themselves dealing with student resistance to learning about biological evolution. Some teachers deal with this pressure by undermining, deemphasizing, or even omitting the topic in their science curriculum. Others face the…
