Osenkowski, Pamela; Green, Che; Tjaden, Anne; Cunniff, Peggy – American Biology Teacher, 2015
Animal dissection has been routinely practiced in American biology classrooms for decades. With technological advancements, more states adopting student choice measures, and increased awareness about ethical concerns surrounding dissection, many useful dissection alternatives have been developed. To understand the current use of animal dissection…

Hodgson, Jay Y. S.; Mateer, Scott C. – American Biology Teacher, 2015
The compound microscope is an important tool in biology, and mastering it requires repetition. Unfortunately, introductory activities for students can be formulaic, and consequently, students are often unengaged and fail to develop the required experience to become proficient in microscopy. To engage students, increase repetition, and develop…

Senter, Phil; Ambrocio, Zenis; Andrade, Julia B.; Foust, Katanya K.; Gaston, Jasmine E.; Lewis, Ryshonda P.; Liniewski, Rachel M.; Ragin, Bobby A.; Robinson, Khanna L.; Stanley, Shane G. – American Biology Teacher, 2015
Lists of vestigial biological structures in biology textbooks are so short that some young-Earth creationist authors claim that scientists have lost confidence in the existence of vestigial structures and can no longer identify any verifiable ones. We tested these hypotheses with a method that is easily adapted to biology classes. We used online…

Robischon, Marcel – American Biology Teacher, 2015
Genetic drift is a concept of population genetics that is central to understanding evolutionary processes and aspects of conservation biology. It is frequently taught using rather abstract representations. I introduce three real-life zoological examples, based on historical and recent color morphs of tigers, tapirs, and ravens, that can complement…

Zeeh, Ann; Quell, Andrew – American Biology Teacher, 2015
Teachers are being challenged to engage students in ways that will elevate student interest and understanding of concepts in science and encourage students to gather evidence to support what we know about science. It is critical for teachers to have budget-friendly, supporting activities that are aligned with current educational standards, that…

Keselman, Alla; Hundal, Savreen; Chentsova-Dutton, Yulia; Bibi, Raquel; Edelman, Jay A. – American Biology Teacher, 2015
This study investigates the relationship among (1) college major, (2) knowledge used in reasoning about common health beliefs, and (3) judgment about the accuracy of those beliefs. Seventy-four college students, advanced biology and non-science majors, indicated their agreement or disagreement with commonly believed, but often inaccurate,…

Davenport, K. D.; Milks, Kirstin Jane; Van Tassell, Rebecca – American Biology Teacher, 2015
Interpreting cladograms is a key skill for biological literacy. In this lesson, students interpret cladograms based on familial relationships and language relationships to build their understanding of tree thinking and to construct a definition of "common ancestor." These skills can then be applied to a true biological cladogram.

Allchin, Douglas – American Biology Teacher, 2015
Playing the sounds of whales during a class period can initiate the awareness of the role of wonder in education. Students are inspired to avidly collect fascinating facts to pique their interest and open the door to learning science. Indeed, when asked, teachers typically identify their foremost practical challenge as trying to motivate…

Bramschreiber, Terry; Westmoreland, David – American Biology Teacher, 2015
Science educators often teach topics that are largely resolved in the scientific community yet remain controversial in broader society. In such cases, students may perceive the teacher as biased. We present two exercises that foster more objective learning about the scientific underpinnings of socially controversial topics. The first exercise…

Hopkins, Robert, II; Alberts, Halley – American Biology Teacher, 2015
This activity is designed as a primer to teaching population dispersion analysis. The aim is to help improve students' spatial thinking and their understanding of how spatial statistic equations work. Students use simulated data to develop their own statistic and apply that equation to experimental behavioral data for Gambusia affinis (western…

Davenport, K. D.; Milks, Kirstin Jane; Van Tassell, Rebecca – American Biology Teacher, 2015
Analyzing evolutionary relationships requires that students have a thorough understanding of evidence and of how scientists use evidence to develop these relationships. In this lesson sequence, students work in groups to process many different lines of evidence of evolutionary relationships between ungulates, then construct a scientific argument…

Baumgartner, Erin; Biga, Lindsay; Bledsoe, Karen; Dawson, James; Grammer, Julie; Howard, Ava; Snyder, Jeffrey – American Biology Teacher, 2015
Quantitative literacy is essential to biological literacy (and is one of the core concepts in "Vision and Change in Undergraduate Biology Education: A Call to Action"; AAAS 2009). Building quantitative literacy is a challenging endeavor for biology instructors. Integrating mathematical skills into biological investigations can help build…

Kelley, Amanda L.; Hanson, Paul R.; Kelley, Stephanie A. – American Biology Teacher, 2015
Ocean acidification, a product of CO[subscript 2] absorption by the world's oceans, is largely driven by the anthropogenic combustion of fossil fuels and has already lowered the pH of marine ecosystems. Organisms with calcium carbonate shells and skeletons are especially susceptible to increasing environmental acidity due to reduction in the…

Lampert, Evan – American Biology Teacher, 2015
Invasive species, defined as exotic species that reach pest status, are major threats to global biodiversity. Although invasive species can belong to any taxonomic group, general characteristics such as rapid growth and reproduction are shared by many invasive species. "Invented Invaders" is a collaborative activity in which students…

Puttick, Gillian; Drayton, Brian; Cohen, Eliza – American Biology Teacher, 2015
We analyzed the practitioner literature on lab-based instruction in biology in "The American Biology Teacher" between 2007 and 2012. We investigated what laboratory learning looks like in biology classrooms, what topics are addressed, what instructional methods and activities are described, and what is being learned about student…
