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…

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,…

Parker, Joyce M.; de los Santos, Elizabeth X.; Anderson, Charles W. – American Biology Teacher, 2015
Our society is currently having serious debates about sources of energy and global climate change. But do students (and the public) have the requisite knowledge to engage these issues as informed citizenry? The learning-progression research summarized here indicates that only 10% of high school students typically have a level of understanding…

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…

Gonda, Rebecca L.; DeHart, Kyle; Ashman, Tia-Lynn; Legg, Alison Slinskey – American Biology Teacher, 2015
Achieving a deep understanding of the many topics covered in middle school biology classes is difficult for many students. One way to help students learn these topics is through scenario-based learning, which enhances students' performance. The scenario-based problem-solving module presented here, "The Strawberry Caper," not only…

Stephens, Philip J. – American Biology Teacher, 2015
A simple and inexpensive method of monitoring the movement of an isolated frog heart provides comparable results to those obtained with a force transducer. A commercially available photoresistor is integrated into a Wheatstone bridge circuit, and the output signal is interfaced directly with a recording device. An excised, beating frog heart is…

Korb, Michele; Colton, Shannon; Vogt, Gina – American Biology Teacher, 2015
Students often find it challenging to create images of complex, abstract biological processes. Using modified storyboards, which contain predrawn images, students can visualize the process and anchor ideas from activities, labs, and lectures. Storyboards are useful in assessing students' understanding of content in larger contexts. They enable…

Çil, Emine – American Biology Teacher, 2015
Students need to be aware of plants in order to learn about, appreciate, care for, and protect them. However, research has found that many children are not aware of the plants in their environment. A way to address this issue might be integration of plants with various disciplines. I investigated the effectiveness of an instructional approach…

Kudrna, Jeremy; Shore, Marta; Wassenberg, Deena – American Biology Teacher, 2015
Anthropogenic climate change (ACC) and evolution are examples of issues that are perceived differently by scientists and the general public. Within the scientific community, there are clear consensuses that human activities are increasing global temperatures (ACC) and that evolutionary mechanisms have led to the biodiversity of life on Earth…

Barrera, Alessandra L. – American Biology Teacher, 2015
This study demonstrates the use of wiki technology (an editable webpage environment) to provide a virtual, asynchronous collaborative-learning environment for students for the purpose of working on course-content-focused study-guide questions. To analyze the effectiveness of this course tool, students' responses to various qualitative and…

Baker, Mohammad A. Abu; Emerson, Sara E.; Brown, Joel S. – American Biology Teacher, 2015
We present a practical field exercise for ecology and animal behavior classes that can be carried out on campus, using urban wildlife. Students document an animal's feeding behavior to study its interactions with the surrounding environment. In this approach, an animal's feeding behavior is quantified at experimental food patches placed within its…

Bland, Mark W.; Morrison, Elizabeth – American Biology Teacher, 2015
Evolution is widely regarded as biology's unifying theme, yet rates of rejection of evolutionary science remain high. Anecdotal evidence suggests that cognitive dissonance leading to an emotional response is a barrier to learning about and accepting evolution. We explored the hypothesis that students whose worldviews may be inconsistent with the…

Zanin, Mary K. B. – American Biology Teacher, 2015
Over the years, many of my students have reported that they enjoy lectures that include short, simple animations. To keep students engaged, I have developed a small set of teaching animations using PowerPoint and Camtasia Studio software packages. A survey of students who learned four difficult topics with traditional written lessons and with…

Carter, B. Elijah; Infanti, Lynn M.; Wiles, Jason R. – American Biology Teacher, 2015
Students who enter college with a solid grounding in, and positive attitudes toward, evolutionary science are better prepared for and achieve at higher levels in university-level biology courses. We found highly significant, positive relationships between student knowledge of evolution and attitudes toward evolution, as well as between…

Garcia, Rebecca; Rahman, Alvina; Klein, Janette Gomos – American Biology Teacher, 2015
We designed a human biology course that interests nonmajors while improving science literacy through student engagement, using a constructivist-inspired, topic-centered approach. This way of learning highlights common diseases that provide a basis to incorporate specific biological concepts. The topic-centered approach triggers interest and…
