Undergraduate Biology Students’ Teleological and Essentialist Misconceptions

Evolutionary stasis: creationism, evolution and climate change in the Accelerated Christian Education curriculum

There has been little consideration in the science education literature of schools or curricula that advocate creationism. Accelerated Christian Education (ACE) is among the world's largest providers of creationist science materials with a curriculum divided into a system of workbooks which students complete at their own speed. This article examines the ways in which ACE presents particular areas of science that it considers to be contentious, namely evolution and climate change. The ACE curriculum has recently been rewritten, and we show that, like previous editions, the current curriculum relies on rote memorisation to the exclusion of other styles of learning, and that information presented is often misleading or distorted. Religious explanations of natural phenomena are sometimes given in place of scientific ones, and creationist assumptions are inserted into lessons not directly related to evolution or the Big Bang. Those who reject creationism are depicted as making an immoral choice. ACE's recent curricula also add material denying the role of humans in climate change. It is argued that both the teaching methods and content of the ACE curriculum place students at an educational disadvantage.

The Use of a Multimodal Case Study To Illustrate Microbial Genetics, Metabolism, and Evolution: The Emergence of VRSA-1

Antibiotic Resistance (ABR) is a global concern and while many students are aware of this issue, many of them are unclear on the mechanisms by which ABR may emerge. The mechanism of horizontal gene transfer is something many students are not familiar with. In this curriculum contribution we present 2 versions of an 'interrupted case study' that is designed as an introduction to horizontal gene transfer for early major students and as a review case for advanced major students in biology and life sciences. The case is based on an authentic patient who developed infections with both methicillin resistant Staphylococcus aureus and vancomycin resistant S. aureus. The interrupted case study is appropriate for small and large groups and engages students while content is introduced in a highly structured way. This type of case study can be done by novice and seasoned instructors and lead to considerable learning gains in both introductory and intermediate microbiology courses.

Intuitive biological thinking in Chinese 8th graders

People spontaneously engage in systematic ways of thinking about biology such as human exceptionalism (the tendency of viewing human species as separate from nonhuman species), essentialism (the tendency of assuming category membership as determined by an underlying essence), and teleology (the tendency of seeing purpose as the cause). However, with the majority of past research drawn on Western samples, little is known about whether various types of intuitive biological thinking apply to non-Western contexts. To better understand the nature and cultural prevalence of intuitive biological thinking, we measured essentialist, teleological, and human exceptionalist thinking in a group of Chinese 8th graders. Results demonstrated the presence of all three types of intuitive biological thinking in Chinese middle schoolers, and comparisons with previously published data on U.S. 8th graders showed consistently less human exceptionalism and slightly higher essentialist thinking in China. As such, the current results highlight the prevalence of intuitive biological thinking in an East Asian sample while addressing the potential role of cultural inputs in shaping the way such thinking manifests.

Effects of Reading Interventions on Student Understanding of and Misconceptions about Antibiotic Resistance

Students possess informal, intuitive ways of reasoning about the world, including biological phenomena. Although useful in some cases, intuitive reasoning can also lead to the development of scientifically inaccurate ideas that conflict with central concepts taught in formal biology education settings, including evolution. Using antibiotic resistance as an example of evolution, we developed a set of reading interventions and an assessment tool to examine the extent to which differences in instructional language affect undergraduate student misconceptions and intuitive reasoning. We find that readings that confront intuitive misconceptions can be more effective in reducing those misconceptions than factual explanations of antibiotic resistance that fail to confront misconceptions. Overall, our findings build upon investigations of intuitive reasoning in biology, examine possible instructional interventions, and raise questions about effective implementation of reading interventions in addressing persistent misconceptions about biology.

Seeing the Woods for the Trees Again: Analyzing Evolutionary Diagrams in German and US University-Level Textbooks

Phylogenetic trees are important tools for teaching and understanding evolution, yet students struggle to read and interpret them correctly. In this study, we extend a study conducted by Catley and Novick (2008) by investigating depictions of evolutionary trees in US textbooks. We investigated 1197 diagrams from 11 German and 11 United States university textbooks, conducting a cross-country comparison and comparing the results with data from the 2008 study. A coding manual was developed based on the 2008 study, with extensions focused on additional important aspects of evolutionary trees. The US and German books showed only a low number of significant differences, typically with very small impacts. In both samples, some characteristics that can render reading trees more difficult or foster misconceptions were found to be prevalent in various portions of the diagrams. Furthermore, US textbooks showed fewer problematic properties in our sample than in the 2008 sample. We conclude that evolutionary trees in US and German textbooks are represented comparably and that depictions in US textbooks have improved over the past 12 years. As students are confronted with comparable depictions of evolutionary relatedness, we argue that findings and materials from one country should easily be transferable to the other.

Stop avoiding the inevitable: The effects of anthropomorphism in science writing for non-experts

While anthropomorphism - the attribution of human characteristics to non-human things or events - is a fundamental part of human psychology and language, some scientists regard it as a source of misconceptions. This creates tension for those writing about science. Taking an experimental approach to diagnosing misconceptions, we compared the effects of anthropomorphic and non-anthropomorphic writing on 174 adult readers' knowledge, understanding, confidence in and connection with the material. Reading any text at all improves readers' knowledge and ability to answer questions. There was no difference in understanding, enjoyment or frequency of anthropomorphic thinking between anthropomorphic and non-anthropomorphic texts. Those who read anthropomorphic text tended to use more vivid examples and fewer generalisations. This suggests that anthropomorphism acts as an evocative, albeit potentially distracting, technique but does not cause significant misconceptions. Writers should feel free to use anthropomorphic techniques if they are appropriate for their topic and their audience.

Implicit associations of teleology and essentialism concepts with genetics concepts among secondary school students

In this article, we present the development and validation of an implicit association test for measuring secondary school students’ associations between genetics concepts and teleology concepts on the one hand, and between genetics concepts and essentialism concepts on the other hand. In total, 169 students from 16 school classes took part in the study, from January 2018 to May 2018. We investigated the strength of the aforementioned associations and the influence of various covariates such as gender, age, school class, or previous learning of biology on the association of teleology or essentialism concepts with genetics concepts through an analysis of covariance and a multi-level analysis. We found moderate associations between genetics and teleology concepts, as well as between genetics and essentialism concepts. These results might reflect a tendency of students of different ages and with various backgrounds to think about genes in terms of goals (teleology) and stability (essentialism), which should be investigated further in future research.

Cognitive Construal-Consistent Instructor Language in the Undergraduate Biology Classroom

Researchers have identified patterns of intuitive thinking that are commonly used to understand and reason about the biological world. These cognitive construals (anthropic, teleological, and essentialist thinking), while useful in everyday life, have also been associated with misconceptions about biological science. Although construal-based thinking is pervasive among students, we know little about the prevalence of construal-consistent language in the university science classroom. In the current research, we characterized the degree to which construal-consistent language is present in biology students' learning environments. To do so, we coded transcripts of instructor's speech in 90 undergraduate biology classes for the presence of construal-consistent language. Classes were drawn from two universities with very different student demographic profiles and represented 18 different courses aimed at nonmajors and lower- and upper-division biology majors. Results revealed construal-consistent language in all 90 sampled classes. Anthropic language was more frequent than teleological or essentialist language, and frequency of construal-consistent language was surprisingly consistent across instructor and course level. Moreover, results were surprisingly consistent across the two universities. These findings suggest that construal-consistent language is pervasive in the undergraduate classroom and highlight the need to understand how such language may facilitate and/or interfere with students learning biological science.
