In 1900, three botanists claimed they had found regularities in inheritance, which soon would be known as Mendel's Laws, without knowing the work of Gregor Mendel or of each other. Their claims of independent (re)discovery have been thoroughly studied during the past decades, with various outcomes. The case is still of interest today as it offers…

This article explores the need to include the science capital and cultural capital of African Americans in science teaching and offers practical exemplars for inclusion in the K-12 science curriculum. The author discusses ideas in the evolution of culture that contribute to the science content and perspectives of current textbooks and their…

We review software for exploring biological evolution from a fun and educational perspective. Our goal is to provide a background explanation of the methods used, terminology, and user experience, and learning outcomes of desktop and mobile evolutionary simulators. Freeware and commercial programs are detailed, with a discussion of how certain…

We highlight some important conceptual issues that biologists should take into account when teaching evolutionary biology or communicating it to the public. We first present conclusions from conceptual development research on how particular human intuitions, namely design teleology and psychological essentialism, influence the understanding of…

An evaluation of the scientific content in a popular children's movie about bees provides an opportunity for discussion about the sources and consequences of scientific misconceptions.

Research shows that students face challenges as they learn about genetic inheritance. The challenges could emanate from the fact that genetic inheritance involves unseen processes at different organizational levels. We explored students' understanding of heredity and related concepts such as cells and reproduction using a Web-based Science Inquiry…

Mainstream scientists often claim that australopithecines such as the specimen nicknamed "Lucy" exhibit anatomy intermediate between that of apes and that of humans and use this as evidence that humans evolved from australopithecines, which evolved from apes. On the other hand, creationists reject evolution and claim that australopithecines are…

Do our genes exclusively control us, or are other factors at play? Epigenetics can provide a means for students to use inquiry-based methods to understand a complex biological concept. Students research and design an experiment testing whether dietary supplements affect the lifespan of Drosophila melanogaster over multiple generations.

Educating students about the process of evolution through natural selection is vitally important because not only is it the unifying theory of biological science, it is also widely regarded as difficult for students to fully comprehend. Anderson and colleagues (2002) describe alternative ideas and misconceptions about natural selection as highly…

Discusses misconceptions and outdated models appearing in biology textbooks for concepts involving bioenergetics and chemical reactions; adenosine triphosphate (ATP) as the energy currency of cells; the myth of high energy phosphate bonds; structural properties of ATP; ATP production from respiration and fermentation; ATP as an energy storage…

Considers topics about cell function often misunderstood, misrepresented, or omitted from biology textbooks: enzyme catalyzed reactions; RNA as a catalyst; protein levels in cells; amino acids; organic acids; glucose and fructose; gluconeogenesis; fatty acids and ketone bodies; diffusion; and transport across membranes. (Contains 25 references.)…

The study conducted addresses issues associated with the relationships among science factual knowledge, conceptual understanding of science, and belief in pseudoscience by means of a 30-question survey. The survey consists of three types of questions asked of students enrolled in a science major and compares the responses to these obtained by…

Across the country, significant percentages of high school teachers are not convinced that evolution is a central concept to biology and/or are of the opinion that creation should be taught in public school science classes. Are these attitudes transferred from educators to their students? Unless educators address this kind of question, they will…
