McKernan, Lisa N. – American Biology Teacher, 2015
The challenge of teaching in the sciences is not only conveying knowledge in the discipline, but also developing essential critical thinking, data analysis, and scientific writing skills. I outline an exercise that can be done easily as part of a microbiology laboratory course. It teaches the nature of the research process, from asking questions…

Bouwma-Gearhart, Jana; Bouwma, Andrew – American Biology Teacher, 2015
The "Next Generation Science Standards" (NGSS Lead States, 2013) recommend that science courses engage communities of students in scientific practices that include building accurate conceptual models of phenomena central to the understanding of scientific disciplines. We offer a set of activities, implemented successfully at both the…

Zeeh, Ann; Quell, Andrew – American Biology Teacher, 2015
Teachers are being challenged to engage students in ways that will elevate student interest and understanding of concepts in science and encourage students to gather evidence to support what we know about science. It is critical for teachers to have budget-friendly, supporting activities that are aligned with current educational standards, that…

Tseng, ChingMei; Chen, Shu-Bi Shu-Bi; Chang, Wen-Hua – American Biology Teacher, 2015
Guiding students to generate testable scientific questions is essential in the inquiry classroom, but it is not easy. The purpose of the BDC ("Big Idea, Divergent Thinking, and Convergent Thinking") instructional model is to to scaffold students' inquiry learning. We illustrate the use of this model with an example lesson, designed…

Davenport, K. D.; Milks, Kirstin Jane; Van Tassell, Rebecca – American Biology Teacher, 2015
Interpreting cladograms is a key skill for biological literacy. In this lesson, students interpret cladograms based on familial relationships and language relationships to build their understanding of tree thinking and to construct a definition of "common ancestor." These skills can then be applied to a true biological cladogram.

Briju, Betsy J.; Wyatt, Sarah E. – American Biology Teacher, 2015
Instructors often present Mendelian genetics and molecular biology separately. As a result, students often fail to connect the two topics in a tangible manner. We have adopted a simple experiment to help link these two important topics in a basic biology course, using red and white onions bought from a local grocery store. A lack of red coloration…

Allchin, Douglas – American Biology Teacher, 2015
Playing the sounds of whales during a class period can initiate the awareness of the role of wonder in education. Students are inspired to avidly collect fascinating facts to pique their interest and open the door to learning science. Indeed, when asked, teachers typically identify their foremost practical challenge as trying to motivate…

Davenport, K. D.; Milks, Kirstin Jane; Van Tassell, Rebecca – American Biology Teacher, 2015
Analyzing evolutionary relationships requires that students have a thorough understanding of evidence and of how scientists use evidence to develop these relationships. In this lesson sequence, students work in groups to process many different lines of evidence of evolutionary relationships between ungulates, then construct a scientific argument…

Parker, Joyce M.; de los Santos, Elizabeth X.; Anderson, Charles W. – American Biology Teacher, 2015
Our society is currently having serious debates about sources of energy and global climate change. But do students (and the public) have the requisite knowledge to engage these issues as informed citizenry? The learning-progression research summarized here indicates that only 10% of high school students typically have a level of understanding…

Dorner, Meredith – American Biology Teacher, 2015
Research shows the importance of active learning, especially within science classes. One way to achieve this goal is to incorporate student-driven projects into the course (e.g., posters). Traditionally, science-poster assignments follow the spirit of the science fair in which a student conducts an experiment and analyzes the results. This article…

Hubler, Tina; Adams, Patti; Scammell, Jonathan – American Biology Teacher, 2015
The molecular basis of evolution is an important concept to understand but one that students and teachers often find challenging. This article provides training and guidance for teachers on how to present molecular evolution concepts so that students will associate molecular changes with the evolution of form and function in organisms. Included…

Puttick, Gillian; Drayton, Brian; Cohen, Eliza – American Biology Teacher, 2015
We analyzed the practitioner literature on lab-based instruction in biology in "The American Biology Teacher" between 2007 and 2012. We investigated what laboratory learning looks like in biology classrooms, what topics are addressed, what instructional methods and activities are described, and what is being learned about student…

Schultheis, Elizabeth H.; Kjelvik, Melissa K. – American Biology Teacher, 2015
Current educational reform calls for increased integration between science and mathematics to overcome the shortcomings in students' quantitative skills. Data Nuggets (free online resource, http://datanuggets.org) are worksheets that bring data into the classroom, repeatedly guiding students through the scientific method and making claims…

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…

Gonda, Rebecca L.; DeHart, Kyle; Ashman, Tia-Lynn; Legg, Alison Slinskey – American Biology Teacher, 2015
Achieving a deep understanding of the many topics covered in middle school biology classes is difficult for many students. One way to help students learn these topics is through scenario-based learning, which enhances students' performance. The scenario-based problem-solving module presented here, "The Strawberry Caper," not only…
