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…

Drits-Esser, Dina; Malone, Molly; Barber, Nicola C.; Stark, Louisa A. – American Biology Teacher, 2014
Epigenetics is the study of how external factors and internal cellular signals can lead to changes in the packaging and processing of DNA sequences, thereby altering the expression of genes and traits. Exploring the epigenome introduces students to environmental influences on our genes and the complexities of gene expression. A supplemental…

Cwikla, Julie; Milroy, Scott; Reider, David; Skelton, Tara – American Biology Teacher, 2014
Pioneering Mars: Turning the Red Planet Green with the Earth's Smallest Settlers (http://pioneeringmars.org) provides a partnership model for STEM (science, technology, engineering, and mathematics) learning that brings university scientists together with high school students to investigate whether cyanobacteria from Antarctica could survive on…

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…

Matthews, Catherine E.; Huffling, Lacey D.; Benavides, Aerin – American Biology Teacher, 2014
We describe a field-based lizard project we did with high school students as a part of our summer Herpetological Research Experiences. We describe data collection on lizards captured, identified, and marked as a part of our mark-recapture study. We also describe other lizard projects that are ongoing in the United States and provide resources for…

Thiet, Rachel K. – American Biology Teacher, 2014
The Mystery Soil Lab, a playful, inquiry-based laboratory project, is designed to develop students' skills of inquiry, soil analysis, and synthesis of foundational concepts in soil science and soil ecology. Student groups are given the charge to explore and identify a "Mystery Soil" collected from a unique landscape within a 10-mile…

Kendall, K. Denise; Niemiller, Matthew L.; Dittrich-Reed, Dylan; Schussler, Elisabeth E. – American Biology Teacher, 2014
Graduate teaching assistants (GTAs) are often used as instructors in undergraduate introductory science courses, particularly in laboratory and discussion sections associated with large lectures. These GTAs are often novice teachers with little opportunity to develop their teaching skills through formal professional development. Focused…

Krupa, James J. – American Biology Teacher, 2014
Large, introductory, nonmajors biology classes present challenges when trying to encourage class discussion to help reinforce important concepts. Lively in-class discussion involving hundreds of students is more successful when a relevant story told with passion is used to introduce a topic. In my courses, each semester begins with thorough…

Moore, Randy – American Biology Teacher, 2014
The alleged "man tracks" beside dinosaur tracks near Glen Rose, Texas, are among the most enduring pieces of evidence used by young-Earth creationists to reject evolution. Despite the tracks' fame, their most persistent advocate--that is, Carl Baugh of the Creation Evidence Museum--has published neither (1) peer-reviewed papers in…

Allen, Denise A. – American Biology Teacher, 2014
Little empirical evidence suggested that independent reading abilities of students enrolled in biology predicted their performance on the Biology I Graduation End-of-Course Assessment (ECA). An archival study was conducted at one Indiana urban public high school in Indianapolis, Indiana, by examining existing educational assessment data to test…

Ligon, Russell A.; Dolezal, Adam G.; Hicks, Michael R.; Butler, Michael W.; Morehouse, Nathan I.; Ganesh, Tirupalavanam G. – American Biology Teacher, 2014
The behavior of animals is an intrinsically fascinating topic for students from a wide array of backgrounds. We describe a learning experience using animal behavior that we created for middle school students as part of a graduate-student outreach program, Graduate Partners in Science Education, at Arizona State University in collaboration with a…

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…

Alozie, Nonye; Mitchell, Claire – American Biology Teacher, 2014
Why is it so hard to get students talking in science class? Who is responsible? Are the students unwilling to speak in class? What kinds of supports are helpful for in-the-moment teaching during classroom discussions in science? We present one high school teacher's facilitation of science discussions while supported by a dialogic discussion…

Weeks, Andrea; Bachman. Beverly; Josway, Sarah; North, Brittany; Tsuchiya, Mirian T.N. – American Biology Teacher, 2013
Microscopy and precise observation are essential skills that are challenging to teach effectively to large numbers of undergraduate biology students. We implemented student-driven digital imaging assignments for microscopy in a large enrollment laboratory for organismal biology. We detail how we promoted student engagement with the material and…

Brewer, Michael S.; Gardner, Grant E. – American Biology Teacher, 2013
Teaching population genetics provides a bridge between genetics and evolution by using examples of the mechanisms that underlie changes in allele frequencies over time. Existing methods of teaching these concepts often rely on computer simulations or hand calculations, which distract students from the material and are problematic for those with…
