In 1988, Robert O'Hara coined the now ubiquitous phrase "tree thinking" to highlight the importance of cladistics for proper evolutionary reasoning. This accessible phrase has been taken up widely in the professional, popular, and educational literatures, and it has played an important role in helping spread phylogenetic thinking far…

The research base on students' knowledge of plants has established that misunderstandings develop in the early years of formal education and can persist through middle, secondary, and tertiary education. The purpose of this article is to demonstrate that a lack of emphasis on teaching biology from an organismic perspective helps explain the range…

Evolution is the central concept of biology and key to a comprehensive understanding of any complex biological interaction. It has proven to be a particularly difficult subject for both teachers and students. Hybrid teaching environments have the potential to support students in learning about complex topics and simultaneously enable researchers…

The recent discovery of preserved cells and soft tissues in certain dinosaur bones seems incompatible with an age of millions of years, given the expectation that cells and soft tissues should have decayed away after millions of years. However, evidence from radiometric dating shows that dinosaur fossils are indeed millions of years old. Under…

As the dual crises of the ongoing COVID-19 pandemic and worsening climate change show, the public must be accurately informed about science. However, many barriers hinder effective messaging about science to the public, including little formal communication training for scientists and an abundance of misleading information from nonscientific…

High school students are very seldomly, if at all, taught that race is a social rather than biological construct, and this pedagogical omission has led to biological essentialism. Biological essentialism is the belief that race can be used in predictable ways to determine intellect and/or behavior. Biological essentialism can result in the belief…

The United States still has one of the lowest evolution acceptance rates in the world. Biology educators have been diligent in their methods to increase evolution acceptance and knowledge, with much success. However, misconceptions still arise through education, textbooks, and even social and religious settings that may influence our citizens' low…

As biologists accumulate or encounter increasingly large and complex data sets, our field creates the need for students to develop skills in data exploration and visualization. Many biology courses lack the time for students to develop the skills needed to parse complex datasets and visualize them appropriately. We developed a new upper-level…

This article provides an account of the role that agential realism might play in sex research, intersexuality and education, as well as the possibilities this opens up for research, institutions, policy, intersex communities and understandings of intersexuality. The account begins by addressing key issues in the field of sex research,…

The change in enthalpy of a chemical reaction conducted at constant pressure is equal to the heat of the reaction plus the nonexpansion work of the reaction, ?H = qP + w[subscript additional]. After deriving that relationship, most general and physical chemistry textbooks set w[subscript additional] = 0 to arrive at the claim that ?H = qP, and…

This article provides computational and rule-based approaches for detecting confusion that is expressed in students' comments in couse forums. To obtain reliable, ground truth data about which posts exhibit student confusion, we designed a decision tree that facilitates the manual labeling of forum posts by experts. However, manual labeling is…

The Hardy-Weinberg principle (HWP) is a fundamental model upon which much of the discipline of population genetics is based. Despite its significance, students often leave introductory biology courses with only a shallow understanding of the use and implications of the HWP. I contend that this deficiency in student comprehension is too-often a…

Racial bias in research impacts a study's relevancy, validity and reliability, though presently this aspect is not addressed in critical appraisal tools, and consequently appraisers may not take racial bias into account when assessing a paper's quality. Drawing on critical race theory (CRT) tenets that racism is ubiquitous and race a social…

Exposure to information about genetics is at an all-time high, while a full understanding of the biocultural complexity of human difference is low. This paper demonstrates the value of an "anthropological approach" to enhance genetics education in biology, anthropology, and other related disciplines, when teaching about human differences…

Computational thinking is a contemporary science and engineering practice that has been introduced to the US science classrooms due to its emphasis in the "Next Generation Science Standards" (NGSS). However, including computational thinking into science instruction may be challenging. Therefore, for biological evolution (an essential…
