Hicks, Melissa A.; Cline, Rebecca J.; Trepanier, Angela M. – American Biology Teacher, 2014
An understanding of how genomics information, including information about risk for common, multifactorial disease, can be used to promote personal health (personalized medicine) is becoming increasingly important for the American public. We undertook a quantitative content analysis of commonly used high school textbooks to assess how frequently…

Suwa, Tomomi; Williamson, Brad – American Biology Teacher, 2014
We present a guided-inquiry biology lesson, using the plant-rhizobium symbiosis as a model system. This system provides a rich environment for developing connections between the big ideas in biology as outlined in the College Board's new AP Biology Curriculum. Students gain experience with the practice of scientific investigation, from…

Machtinger, Erika T. – American Biology Teacher, 2014
Hands-on activities with live organisms allow students to actively explore scientific investigation. Here, I present activities that combine guided inquiry with direct instruction and relate how nutrition affects the physiology and behavior of the common housefly. These experiments encourage student involvement in the formulation of experimental…

Chudyk, Sarah; McMillan, Amy; Lange, Catherine – American Biology Teacher, 2014
This article contains an original 5E lesson plan developed from conservation genetics research on the giant North American hellbender salamander, Cryptobranchus alleganiensis alleganiensis. The lesson plan provides background information on the hellbender, reviews basic genetics, and exposes students to the scientific process that is used during…

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…

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…

Christensen, Doug – American Biology Teacher, 2013
Understanding how DNA banding patterns in a gel can aid in the conviction or exoneration of suspects and be utilized for positive identification of biological fathers in paternity cases can be intimidating. In reality, the logistics and technology used in such cases are rather straightforward. This exercise is designed for use in high school…

Stansfield, William D. – American Biology Teacher, 2013
Students should not graduate from high school without understanding that scientific debates are essential components of scientific methodology. This article presents a brief history of ongoing debates regarding the hypothesis that group selection is an evolutionary mechanism, and it serves as an example of the role that debates play in correcting…

McAlpine, Lisa K. – American Biology Teacher, 2013
In this activity for the beginning of a high school Biology 1 evolution unit, students are challenged to reconstruct organisms found in an owl pellet as a model for fossil reconstruction. They work in groups to develop hypotheses about what animal they have found, what environment it inhabited, and what niche it filled. At the end of the activity,…

Chan, Kit Yu Karen; Yang, Sylvia; Maliska, Max E.; Grunbaum, Daniel – American Biology Teacher, 2012
The National Science Education Standards have highlighted the importance of active learning and reflection for contemporary scientific methods in K-12 classrooms, including the use of models. Computer modeling and visualization are tools that researchers employ in their scientific inquiry process, and often computer models are used in…

Porta, Angela R.; Enners, Edward – American Biology Teacher, 2012
The polymerase chain reaction (PCR) is a common technique used in high school and undergraduate science teaching. Students often do not fully comprehend the underlying principles of the technique and how optimization of the protocol affects the outcome and analysis. In this molecular biology laboratory, students learn the steps of PCR with an…

Sauterer, Roger; Rayburn, James R. – American Biology Teacher, 2012
Introducing students to the process of scientific inquiry is a major goal of high school and college labs. Environmental toxins are of great concern and public interest. Modifications of a vertebrate developmental toxicity assay using the frog Xenopus laevis can support student-initiated toxicology experiments that are relevant to humans. Teams of…

Lenz, Laura; Willcox, Maia K. – American Biology Teacher, 2012
In today's global society, with science and technology advancing at a rapid pace, issues about biological topics are common. A typical standards-based high school or general college-level biology classroom naturally lends itself to teaching issue-oriented science. In an issue-oriented classroom, students analyze and discuss personal, societal, and…

Riechert, Susan E.; Post, Brian K. – American Biology Teacher, 2010
The national Science, Technology, Engineering, and Math (STEM) Education Initiative favors a curriculum shift from the compartmentalization of math and science classes into discrete subject areas to an integrated, multidisciplinary experience. Many states are currently implementing programs in high schools that provide greater integration of math,…
