Hubler, Tina; Adams, Patti; Scammell, Jonathan – American Biology Teacher, 2015
The molecular basis of evolution is an important and challenging concept for students to understand. In a previous article, we provided some of the scientific background necessary to teach this topic. This article features a series of laboratory activities demonstrating that molecular events can alter the genomes of organisms. These activities are…

Cooper, Robert A. – American Biology Teacher, 2015
This paper presents an activity that engages students in model-based reasoning, requiring them to predict the behavior of the trp and lac operons under different environmental conditions. Students are presented six scenarios for the "trp" operon and five for the "lac" operon. In most of the scenarios, specific mutations have…

Farenga, Stephen J.; Niess, Daniel; Hutchinson, Michael – American Biology Teacher, 2015
Learning about stem cells within the context of treating pet illness or injury is an additional way for teachers to discuss the integration of science, technology, and veterinary medicine. We explain how practitioners in veterinary medicine harvest animal stem cells from adipose (fat) tissue in treating pet illness or injury. Further, we narrate…

Nash, Troy R.; Yang, Suann; Inman, John C. – American Biology Teacher, 2015
We describe an alternative to the kinds of observation-based lab exercises that are often used to cover animal and plant evolution with respect to transitioning from aquatic to terrestrial habitats. We wrote this activity to address these objectives, but also to model the process of scientific inquiry and to require students to collect and analyze…

Taylor, Jessica M.; Davidson, Rebecca M.; Strong, Michael – American Biology Teacher, 2014
Tuberculosis (TB) continues to be a serious global health problem, resulting in >1.4 million deaths each year. Of increasing concern is the evolution of antibiotic resistant strains of the bacterium that causes TB. Using this real-world scenario, we created a 90-minute activity for high school or undergraduate students to use online…

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…

Stanger-Hall, Kathrin F.; Wenner, Julianne A. – American Biology Teacher, 2014
We assessed the performance of students with a self-reported conflict between their religious belief and the theory of evolution in two sections of a large introductory biology course (N = 373 students). Student performance was measured through pretest and posttest evolution essays and multiple- choice (MC) questions (evolution-related 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…

Wyner, Yael; Becker, Johnathan; Torff, Bruce – American Biology Teacher, 2014
Both the old National Science Education Standards (NSES) and the recent "Next Generation Science Standards" (NGSS) devote significant resources to learning about human environmental impact. Whereas the NSES advocate learning about human environmental impact in a section apart from the science- content learning strands, the NGSS embed…

May, S. Randolph; Cook, David L.; May, Marilyn K. – American Biology Teacher, 2013
Biology courses have thousands of words to learn in order to intelligently discuss the subject and take tests over the material. Biological fluency is an important goal for students, and practical methods based on constructivist pedagogies can be employed to promote it. We present a method in which pairs of students write dialogues from…

Schanker, Neil B. – American Biology Teacher, 1995
Describes how one instructor developed a biology questionnaire designed to get students interacting and thinking about biology course content on the first day of class. Discusses why student interest is captured, how the questions are made, and how the questionnaire results are used in class. Contains a 15-question true/false questionnaire. (LZ)

Esbenshade, Donald H., Jr. – American Biology Teacher, 1993
Presents insights into the depth and importance of religious issues for students in science classes. Among the findings are that 69% of surveyed private academy students interested in a science career indicated that personal faith could affect their career choice. (PR)

Duhrkopf, Richard, Ed.; Bell, Nancy B., Ed. – American Biology Teacher, 1989
Describes procedures for choosing process skill materials for evaluation. Steps include selecting software titles, reading descriptions, and skimming for key phrases associated with process skills, examining courseware, considering cost versus time, and the selecting process. Sample forms for the evaluation process are included. (RT)
