Teaching about Scientific Origins: Taking Account of Creationism

The purpose of this study was to develop a model for measuring experimental design ability based on functional magnetic resonance imaging (fMRI) during biological inquiry. More specifically, the researchers developed an experimental design task that measures experimental design ability. Using the developed experimental design task, they measured both the paper experimental design ability and the fMRI experimental design ability of subjects. Subjects’ paper experimental design ability was measured using the quotient equation of experimental design ability, and their fMRI experimental design ability using the brain connectivity coefficient. According to the fMRI results, differences in design ability existed among subjects in terms of brain connectivity coefficient level during the experimental design task. The experimental design ability brain connectivity coefficient level and quotient for each subject were analysed. Statistically significant correlations between subjects’ connectivity strength level among brain activation regions and quotient value guided the establishment of a measuring model. The model measured experimental design ability and could predict an individual’s experimental design ability quotient using his or her brain connectivity coefficient. Hence, the model developed for this study for measuring experimental design ability based on fMRI may serve as a practical measurement of students’ scientific experimental design ability. Furthermore, this study could serve as a founding theory for measuring models of other scientific processing abilities such as observation, question generation, classification, hypothesis generation and hypothesis evaluation.     

Creationism in Germany and its Possible Cause

In a widely cited essay published in the journal Science (Aug. 2006), it was stated that in Germany a large majority of adults are convinced of evolution. Based on a new poll, I document that this conclusion is questionable. In Sept. 2005, 60.9% of the German population accepted naturalistic evolution, whereas 37.7% were creationists or adherents of intelligent design. Because among Christians of both confessions the percentage of anti-evolutionists is much larger than among atheists, I suggest that religious indoctrination of children may in part be responsible for the rejection of the concept of evolution, notably in the western part of Germany.

Creationism and evolution: it's the American way

The recent ruling in the Kitzmiller v. Dover court case that intelligent design is a form of religion and cannot be taught alongside evolution in science classes in US public schools garnered worldwide attention. But why is the antievolution movement so powerful in the United States?     

New England Faculty and College Students Differ in Their Views About Evolution, Creationism, Intelligent Design, and Religiosity

Public acceptance of evolution in Northeastern U.S. is the highest nationwide, only 59%. Here, we compare perspectives about evolution, creationism, intelligent design (ID), and religiosity between highly educated New England faculty (n = 244; 90% Ph.D. holders in 40 disciplines at 35 colleges/universities) and college students from public secular (n = 161), private secular (n = 298), and religious (n = 185) institutions: 94/3% of the faculty vs. 64/14% of the students admitted to accepting evolution openly and/or privately, and 82/18% of the faculty vs. 58/42% of the students thought that evolution is definitely true or probably true, respectively. Only 3% of the faculty vs. 23% of the students thought that evolution and creationism are in harmony. Although 92% of faculty and students thought that evolution relies on common ancestry, one in every four faculty and one in every three students did not know that humans are apes; 15% of the faculty vs. 34% of the students believed, incorrectly, that the origin of the human mind cannot be explained by evolution, and 30% of the faculty vs. 72% of the students was Lamarckian (believed in inheritance of acquired traits). Notably, 91% of the faculty was very concerned (64%) or somehow concerned (27%) about the controversy evolution vs creationism vs ID and its implications for science education: 96% of the faculty vs. 72% of the students supported the exclusive teaching of evolution while 4% of the faculty vs. 28% of the students favored equal time to evolution, creationism and ID; 92% of the faculty vs. 52% of the students perceived ID as not scientific and proposed to counter evolution or as doctrine consistent with creationism. Although ≈30% of both faculty and students considered religion to be very important in their lives, and ≈20% admitted to praying daily, the faculty was less religious (Religiosity Index faculty = 0.5 and students = 0.75) and, as expected, more knowledgeable about science (Science Index faculty = 2.27 and students = 1.60) and evolution (Evolution Index faculty = 2.48 and students = 1.65) than the students. Because attitudes toward evolution correlate (1) positively with understanding of science/evolution and (2) negatively with religiosity/political ideology, we conclude that science education combined with vigorous public debate should suffice to increase acceptance of naturalistic rationalism and decrease the negative impact of creationism and ID on society’s evolution literacy.     

Enhancing the Teaching of Evolution in Public Health

Public health courses are emerging as popular undergraduate offerings, especially at universities with schools of public health. It is important to note that evolution has shaped the burden of disease in the modern world in which we practice and educate for public health. Human cultures and technologies have modified life on Planet Earth and have co-evolved with myriad other species, including microorganisms, plant and animal sources of food, invertebrate vectors of disease, and intermediate bird, mammal, and primate hosts. Molecular mechanisms of evolution have produced differential resistance or susceptibility to infectious agents, including malaria, plague, smallpox, TB, measles, and diarrheal and respiratory diseases. The domestication of sheep and cattle led to natural selection in favor of human populations able to digest milk throughout life through persistence into adulthood of lactase enzyme expression in the intestine, a major story of anthropology. The emergence of a “Western diet” of dairy, refined cereal grains, refined sugars, vegetable oils, alcoholic beverages, salt, and omega-6-rich meats has dramatically altered glycemic load, fatty acid composition, macronutrients, acid–base balance, sodium/potassium ratio, and fiber content. This is a major story of nutrition and disease. The results include epidemics of atherosclerotic cardiovascular disease, obesity, diabetes, high blood pressure, osteoporosis, certain cancers, and bowel, inflammatory, and autoimmune disorders. Another interesting phenomenon is the selection of excessive hemostatic activity from platelets and the plasma clotting proteins; what was protective against death from bleeding after injuries among hunter–gatherers or from pregnancy-related hemorrhage now contributes to thrombosis underlying heart attacks and strokes. Conversely, there is little pressure against hemostasis and thrombosis since deaths from these causes occur mostly after the reproductive years of life. Learning about evolution over millennia for humans and over hours or days for microbes enlivens the experience of understanding evolutionary biology in public health context.     

Teaching the Evolution of Morality: Status and Resources

Recent studies now provide a relatively robust explanation of how moral behavior evolved, perhaps not just in humans. An analysis of current biology textbooks shows that they fail to address this critical topic fully. Here, I survey resources—books, images, and videos—that can guide educators in meeting the challenge of teaching the biology of morality.     

The Pleasures and Pitfalls of Teaching Human Evolution in the Museum

As natural history museums are increasingly challenged to represent the complexities of human evolution, new innovations are required to create dynamic, dialogic experiences between museum scientists and museum audiences. After the opening of the Spitzer Hall of Human Origins in 2006, I had the opportunity to take my academic experience in physical anthropology to public education in the Sackler Educational Laboratory for Comparative Genomics and Human Origins. In the lab, I was able to intervene in museum visitors’ preconceptions of human evolution in a novel, informal educational setting.     

Evolution Education: Seeing the Forest for the Trees and Focusing Our Efforts on the Teaching of Evolution

Evolution is the underlying framework upon which all biology is based; however, when it comes to learning evolutionary concepts, many students encounter obstacles. There are many reasons as to why these obstacles occur. These reasons deal with evolution being treated as a discrete topic among many within a biology curriculum, misunderstanding the nature of science, and personal difficulties with understanding due to evolution’s seemingly abstract nature. In this article, we propose a different way of thinking about and teaching evolution in grades K-12, and it surrounds four core areas essential to the understanding of evolution: variation, selection, inheritance, and deep time. Possibilities for how these areas can affect learning are described and implications for assessment are also discussed.     

Teaching Evolution with Historical Narratives

This paper focuses on evolution as a unifying theme in biology education. Our aim is to argue that the different topics taught in secondary school biology classes should be enriched with and linked together by means of accounts of the history of life. We named this approach a “natural history perspective” on biology education. An essential aspect of the natural history perspective is the claim that evolutionary history forms the context for the development of an understanding of evolutionary processes. While there are some indications that a natural history perspective can function as a context for understanding micro-evolutionary processes, more research is called for.
