Miller, Jon S.; Toth, Ronald – American Biology Teacher, 2014
We describe how the increased level of religiosity in the United States is correlated with the resistance to the teaching of evolution and argue that this is a social, rather than scientific, issue. Our goal is to foster teachers' understanding of the philosophy of biology and encourage them to proactively deal with creationism at all levels,…

Saunders, Cheston; Taylor, Amy – American Biology Teacher, 2014
Many students leave the biology classroom with misconceptions centered on cellular structure. This article presents an activity in which students utilize images from an online database called "The Cell: An Image Library" (http://www.cellimagelibrary. org/) to gain a greater understanding of the diversity of cellular structure and the…

Stuart, Parker E.; Lees, Kelsey D.; Milanick, Mark A. – American Biology Teacher, 2014
In this practice-based lab, students are provided with four Olympic athlete profiles and simulated blood and urine samples to test for illegal substances and blood-doping practices. Throughout the course of the lab, students design and conduct a testing procedure and use their results to determine which athletes won their medals fairly. All of the…

Robischon, Marcel A. – American Biology Teacher, 2014
Gas diffusion, as a basis for complex biological processes such as respiration, is a core principle for understanding fundamental physiology. Students, however, often find these concepts challenging, in particular when expressed formally as in Fick's law of gas diffusion. This introduction to Fick's law uses the representations of…

Bierema, Andrea M.-K.; Rudge, David W. – American Biology Teacher, 2014
One of the key aspects of natural selection is competition, yet the concept of competition is not necessarily emphasized in explanations of natural selection. Because of this, we developed an activity for our class that focuses on competition and provides an example of the effects of competition on natural selection. This hands-on activity models…

Bal, Tara L. – American Biology Teacher, 2014
"Forest health" is an important concept often not covered in tree, forest, insect, or fungal ecology and biology. With minimal, inexpensive equipment, students can investigate and conduct their own forest health survey to assess the percentage of trees with natural or artificial wounds or stress. Insects and diseases in the forest are…

Seager, Robert D. – American Biology Teacher, 2014
In learning genetics, many students misunderstand and misinterpret what "dominance" means. Understanding is easier if students realize that dominance is not a mechanism, but rather a consequence of underlying cellular processes. For example, metabolic pathways are often little affected by changes in enzyme concentration. This means that…

Hewitt, Krissi M.; Kayes, Lori J.; Hubert, David; Chouinard, Adam – American Biology Teacher, 2014
Recent reform initiatives in undergraduate biology call for curricula that prepare students for dealing with real-world issues and making important links between science and society. In response to this call, we have developed an issues-based laboratory module that uses guided inquiry to integrate the concepts of animal behavior and population…

Jasti, Chandana; Hug, Barbara; Waters, Jillian L.; Whitaker, Rachel J. – American Biology Teacher, 2014
Recent scientific studies are providing increasing evidence for how microbes living in and on us are essential to our good health. However, many students still think of microbes only as germs that harm us. The classroom activities presented here are designed to shift student thinking on this topic. In these guided inquiry activities, students…

Blair, Amy C.; Peters, Brenda J.; Bendixen, Conrad W. – American Biology Teacher, 2014
The AAAS Vision and Change report (2011) recommends incorporating student research experiences into the biology curriculum at the undergraduate level. This article describes, in detail, how "Zea mays" (corn) cultivars were used as a model for a hypothesis-driven short-term research project in an introductory biology course at a small…

Schauer, Alexandria; Cotner, Sehoya; Moore, Randy – American Biology Teacher, 2014
Students regard evolutionary theory differently than science in general. Students' reported confidence in their ability to understand science in general (e.g., posing scientific questions, interpreting tables and graphs, and understanding the content of their biology course) significantly outweighed their confidence in understanding evolution. We…

Cavanagh, J. William; Martinez, Kimberly M.; Higgins, Benjamin A.; Horn, Michael H. – American Biology Teacher, 2014
A collaborative effort between a junior high school and a nearby university allowed 40 eighth-grade honors students to engage in a scientific investigation within a university laboratory. These students, with their science teachers and university researchers, gathered data on egg cannibalism in a beach-spawning fish and thereby contributed to an…

Wu, Jen-Yi; Tung, Yu-Neng; Hwang, Bi-Chi; Lin, Chen-Yung; Che-Di, Lee; Chang, Yung-Ta – American Biology Teacher, 2014
Various sequences for teaching genetics have been proposed. Three seventh-grade biology textbooks in Taiwan share similar key knowledge assemblages but have different knowledge arrangements. To investigate the influence of knowledge arrangements on student understanding of genetics, we compared students' reading comprehension of the three texts…

Stanger-Hall, Kathrin F.; Wenner, Julianne A. – American Biology Teacher, 2014
We assessed the performance of students with a self-reported conflict between their religious belief and the theory of evolution in two sections of a large introductory biology course (N = 373 students). Student performance was measured through pretest and posttest evolution essays and multiple- choice (MC) questions (evolution-related and…

Lockwood, Stephanie A.; Miller, Amanda J.; Cromie, Meghan M. – American Biology Teacher, 2014
Formal professional development programs for biology graduate students interested in becoming faculty members have come far; however, programs that provide advanced teaching experience for seasoned graduate teaching assistants are scarce. We outline an advanced program that focuses on further training of graduate teaching assistants in pedagogy…
