Lampert, Evan – American Biology Teacher, 2014
"Biology Myth-Killers" is an activity designed to identify and correct common misconceptions for high school and college introductory biology courses. Students identify common myths, which double as biology misconceptions, and use appropriate sources to share the "truth" about the myths. This learner-centered activity is a fun…

Taylor, John R. – American Biology Teacher, 2014
This simple inquiry-based lab was designed to teach the principle of osmosis while also providing an experience for students to use the skills and practices commonly found in science. Students first design their own experiment using very basic equipment and supplies, which generally results in mixed, but mostly poor, outcomes. Classroom "talk…

Reddy, Christopher – American Biology Teacher, 2014
Interactive television is a type of distance education that uses streaming audio and video technology for real-time student-teacher interaction. Here, I discuss the design and logistics for developing a high school laboratory-based science course taught to students at a distance using interactive technologies. The goal is to share a successful…

Unsworth, Elizabeth – American Biology Teacher, 2014
Identification of macromolecules in food is a standard introductory high school biology lab. The intent of this article is to describe the conversion of this standard cookbook lab into an inquiry investigation. Instead of verifying the macromolecules found in food, students use their knowledge of the macromolecules in food to determine the…

Spaccarotella, Kim; James, Roxie – American Biology Teacher, 2014
Measuring plant stem growth over time is a simple activity commonly used to introduce concepts in growth and development in plant biology (Reid & Pu, 2007). This Quick Fix updates the activity and incorporates a real-world application: students consider possible effects of soil substrate and sunlight conditions on plant growth without needing…

Weigel, Emily G.; DeNieu, Michael; Gall, Andrew J. – American Biology Teacher, 2014
This lesson is designed to teach students that behavior is a trait shaped by both genes and the environment. Students will read a scientific paper, discuss and generate predictions based on the ideas and data therein, and model the relationships between genes, the environment, and behavior. The lesson is targeted to meet the educational goals of…

Holding, Matthew L.; Denton, Robert D.; Kulesza, Amy E.; Ridgway, Judith S. – American Biology Teacher, 2014
A fundamental component of science curricula is the understanding of scientific inquiry. Although recent trends favor using student inquiry to learn concepts through hands-on activities, it is often unclear to students where the line is drawn between the content and the process of science. This activity explicitly introduces students to the…

Simpson, Jeff S. – American Biology Teacher, 2014
Because of shrinking budgets and computerized virtual dissection programs, many large and small institutions are closing the door on traditional and expensive cadaver dissection classes. However, many health-care educators would argue there is still a place for cadaver dissection in higher education, so the continuing challenge is to provide the…

Kampourakis, Kostas; Minelli, Alessandro – American Biology Teacher, 2014
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…

Eliyahu, Dorit – American Biology Teacher, 2014
I present an activity to help students make the connection between meiosis and genetic variation. The students model meiosis in the first phase of the activity, and by that process they produce gametes of a fictitious reptilobird species, "Chromoseratops meiosus." Later on, they will "mate" their gametes and produce a zygote…

Smith, Mike U. – American Biology Teacher, 2014
Genetics is perhaps the most rapidly growing field of science today. Recent findings such as those of the Human Genome Project have led to new understandings of basic genetic phenomena and even to increased confusion about some basic genetic ideas, such as the nature of the gene. These developments directly influence how we should teach genetics.…

Smith, Mike U. – American Biology Teacher, 2014
In a companion article, I discussed recent developments in genetics and the inadequacies of eight common claims made by biology teachers, followed by suggested replacement language for those statements. In the present article, I address nine more claims, about such topics as whether or not most human characteristics are inherited as simple…

Liang, Jennifer O.; Noll, Matthew; Olsen, Shayna – American Biology Teacher, 2014
We have developed an upper-level undergraduate laboratory exercise that enables students to replicate a key experiment in developmental biology. In this exercise, students have the opportunity to observe live chick embryos and stain the apical ectodermal ridge, a key tissue required for development of the vertebrate limb. Impressively, every…

Gerido, Leona; Curran, Mary Carla – American Biology Teacher, 2014
Technology use in science classes can enhance lessons and reinforce scientific content. The creation of multimedia projects is a great way to engage students in lessons about estuarine ecosystems. In this activity, students can learn about estuarine organisms and use their creativity to write a story, create artwork, and develop a multimedia…

White, Joshua S.; Maskiewicz, April C. – American Biology Teacher, 2014
Using a design-based research approach, we developed a data-rich problem (DRP) set to improve student understanding of cellular respiration at the ecosystem level. The problem tasks engage students in data analysis to develop biological explanations. Several of the tasks and their implementation are described. Quantitative results suggest that…
