Blazek, Joshua D.; Cooper, Gary L.; Judd, Mariah V.; Roper, Randall J.; Marrs, Kathleen A. – American Biology Teacher, 2013
The National Science Foundation's GK-12 program provides a unique opportunity for STEM collaboration between the K-12 classroom and university research. This partnership benefits students through experiential learning, exposure to research, exceptional mentorship, and preparation for postsecondary education. Additionally, researchers gain…

Ray, Darrell L. – American Biology Teacher, 2013
Students often enter biology programs deficient in the math and computational skills that would enhance their attainment of a deeper understanding of the discipline. To address some of these concerns, I developed a series of spreadsheet simulation exercises that focus on some of the mathematical foundations of scientific inquiry and the benefits…

Loftin, Madelene; Lamb, Neil E. – American Biology Teacher, 2013
The "Biotechnology Discoveries and Applications" guidebook aims to provide teachers with an overview of the recent advances in genetics and biotechnology, allowing them to share these findings with their students. The annual guidebook introduces a wealth of modern genomic discoveries and provides teachers with tools to integrate exciting…

Lau, Kwok-chi – American Biology Teacher, 2013
This article presents a tangible model used to help students tackle some misconceptions about enzyme actions, particularly the induced-fit model, enzyme-substrate complementarity, and enzyme inhibition. The model can simulate how substrates induce a change in the shape of the active site and the role of attraction force during enzyme-substrate…

Lakrim, Mohamed – American Biology Teacher, 2013
The transport of water in plants is among the most difficult and challenging concepts to explain to students. It is even more difficult for students enrolled in an introductory general biology course. An easy approach is needed to demonstrate this complex concept. I describe visual and pedagogical examples that can be performed quickly and easily…

Christensen, Doug – American Biology Teacher, 2013
Understanding how DNA banding patterns in a gel can aid in the conviction or exoneration of suspects and be utilized for positive identification of biological fathers in paternity cases can be intimidating. In reality, the logistics and technology used in such cases are rather straightforward. This exercise is designed for use in high school…

Sengupta, Sibani – American Biology Teacher, 2013
RNA interference (abbreviated RNAi) is a relatively new discovery in the field of mechanisms that serve to regulate gene expression (a.k.a. protein synthesis). Gene expression can be regulated at the transcriptional level (mRNA production, processing, or stability) and at the translational level (protein synthesis). RNAi acts in a gene-specific…

Vandervoort, Frances S. – American Biology Teacher, 2013
Oscar Riddle, born in Indiana in 1877, was an ardent evolutionist and a key player in the founding of the National Association of Biology Teachers in 1938. He studied heredity and behavior in domestic pigeons and doves with Charles O. Whitman of the University of Chicago, received his Ph.D. in zoology in 1907, and in 1912 began a long career at…

Yahnke, Christopher J.; Dewey, Tanya; Myers, Phil – American Biology Teacher, 2013
Most teachers agree that writing is an important skill for students to master, yet not all teachers incorporate writing assignments in their courses. Employers agree that written communication is important for college graduates, yet in a survey, less than 10% of employers thought that colleges did a good job preparing students for work. Writing an…

Heil, Caiti S. S.; Manzano-Winkler, Brenda; Hunter, Mika J.; Noor, Juliet K. F.; Noor, Mohamed A. F. – American Biology Teacher, 2013
We present a laboratory exercise that leverages student interest in genetics to observe and understand evolution by natural selection. Students begin with white-eyed fruit fly populations, to which they introduce a single advantageous variant (one male with red eyes). The superior health and vision associated with having the red-eye-color allele…

Flammer, Larry – American Biology Teacher, 2013
Students compare banding patterns on hominid chromosomes and see striking evidence of their common ancestry. To test this, human chromosome no. 2 is matched with two shorter chimpanzee chromosomes, leading to the hypothesis that human chromosome 2 resulted from the fusion of the two shorter chromosomes. Students test that hypothesis by looking for…

Stansfield, William D. – American Biology Teacher, 2013
Before beginning a series of presentations on evolution, it would be prudent to survey the general level of students' understanding of prerequisite basic concepts of reproduction, heredity, ontology, and phenotypic diversity so that teachers can avoid devoting time to well-known subjects of general knowledge and can spend more time on subjects…

Senter, Phil – American Biology Teacher, 2013
Many anatomy students begin the course with a misconception that human males and females do not have the same number of ribs. At the root of that misconception is Genesis 2:21-22, in which God removes a rib from Adam to make Eve. Removal of a body part is a surgical procedure, and one does not pass on the results of surgery to one's offspring. The…

Lee, Il-Sun; Byeon, Jung-Ho; Kwon, Yong-Ju – American Biology Teacher, 2013
The purpose of this study was to design a teaching method suitable for science high school students using atomic force microscopy. During their scientific inquiry procedure, high school students observed a micro-nanostructure of a biological sample, which is unobservable via an optical microscope. The developed teaching method enhanced students'…

Heyborne, William – American Biology Teacher, 2013
The increase in "big box" stores over the past decade has provided a great source of specimens for use in teaching diversity in biology.
