Work, Kirsten A.; Gibbs, Melissa A.; Friedman, Erich J. – American Biology Teacher, 2015
We describe a card game that helps introductory biology students understand the basics of the immune response to pathogens. Students simulate the steps of the immune response with cards that represent the pathogens and the cells and molecules mobilized by the immune system. In the process, they learn the similarities and differences between the…

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,…

Peterson, Jacob – American Biology Teacher, 2014
A logical question to be expected from students: "How could life develop, that is, change, evolve from simple, primitive organisms into the complex forms existing today, while at the same time there is a generally observed decline and disorganization--the second law of thermodynamics?" The explanations in biology textbooks relied upon by…

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…

Romesburg, H. Charles – American Biology Teacher, 2014
This article explains four kinds of inquiry exercises, different in purpose, for teaching advanced-level high school and college students the hypothetico-deductive (H-D) method. The first uses a picture of a river system to convey the H-D method's logic. The second has teams of students use the H-D method: their teacher poses a hypothesis…

Lark, Amy; Richmond, Gail; Pennock, Robert T. – American Biology Teacher, 2014
New science standards and reform recommendations spanning grades K--16 focus on a limited set of key scientific concepts from each discipline that all students should know. They also emphasize the integration of these concepts with science practices so that students learn not only the "what" of science but also the "how" and…

Medina, Stephanie R.; Ortlieb, Evan; Metoyer, Sandra – American Biology Teacher, 2014
Science content knowledge is a concern for educators in the United States because performance has stagnated for the past decade. Investigators designed this study to determine the current levels of scientific literacy among undergraduate students in a freshman-level biology course (a core requirement for majors and nonmajors), identify factors…

Brown, Julie C. – American Biology Teacher, 2013
In this two-part activity, high school biology students examine human karyotyping, sex-chromosome-linked disorders, and the relationship between biological sex and gender. Through interactive simulations and a structured discussion lab, students create a human karyotype and diagnose chromosomal disorders in hypothetical patients, as well as…

Richter, Dana L. – American Biology Teacher, 2013
A simple method is presented to show kids the size of a microbe--a fungus hypha--compared to a human hair. Common household items are used to make sterile medium on a stove or hotplate, which is dispensed in the cells of a weekly plastic pill box. Mold fungi can be easily and safely grown on the medium from the classroom environment. A microscope…

Kim, Youngshin; Lim, Soo-Min; Lee, Il-Sun – American Biology Teacher, 2013
Cultivation of microorganisms such as fungi and bacteria is often not included in scientific inquiries conducted in school because of the difficulty of manufacturing a suitable medium. A method using dry rehydratable film to reduce the need to manufacture a suitable medium and shorten incubation time was developed as an efficient microbial testing…

Bybee, Rodger W. – American Biology Teacher, 2012
The release of A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (NRC, 2012) provides the basis for the next generation of science standards. This article first describes that foundation for the life sciences; it then presents a draft standard for natural selection and evolution. Finally, there is a…

Harley, Suzanne M. – American Biology Teacher, 2010
Charles Darwin's botanical studies provide a way to expose students to his work that followed the publication of "On the Origin of Species." We can use stories from his plant investigations to illustrate key concepts in the life sciences and model how questions are asked and answered in science.

Strain, Steven R.; Chmielewski, Jerry G. – American Biology Teacher, 2010
The National Science Education Standards prescribe that an understanding of the importance of classifying organisms be one component of a student's educational experience in the life sciences. The use of a classification scheme to identify organisms is one way of addressing this goal. We describe Conifer ID, a computer application that assists…

DeSantis, Larisa R. G. – American Biology Teacher, 2009
Antibiotic resistance, genetically modified produce, avian flu, and invasive species persistence are just a few scientific issues pulled from the headlines that affect society on a daily basis. Understanding these issues requires knowledge of evolutionary processes. Educating students about evolution may never have been as necessary as it is…

Weese, J. Scott – American Biology Teacher, 2009
A wide range of activities may be undertaken in elementary and secondary school science laboratories as part of regular curricular activities or optional classroom activities, including science fair projects. Among these is the culturing of microorganisms such as bacteria or fungi. There are various potential educational opportunities associated…
