Biological interactions and associations underlie life's processes at every level of organization. Here, we present a classroom activity that allows students to visualize and understand the connections within almost any biological system, from cell functions to ecological relationships. We recommend that instructors implement this activity to…

Distance learning requires the combined use of techniques because it is more complicated to keep the students' attention. This exercise is designed to explain the inactivation of the x-chromosome in humans and is intended to complement the theoretical explanations. It is estimated that it lasts two hours and makes use of different web resources.…

Learning about chromosomes is standard fare in biology classrooms today. However, students may find it difficult to understand the relationships among the "genome", "chromosomes", "genes", a "gene locus", and "alleles". In the simple activity described in this article, which follows the 5E approach…

To fully appreciate genetics, one must understand the link between genotype (DNA sequence) and phenotype (observable characteristics). Advances in high-throughput genomic sequencing technologies and applications, so-called "-omics," have made genetic sequencing readily available across fields in biology from applications in…

In fall of 2019, a new capstone course, wildlife biology, was offered as part of the biology curriculum at the University of Saint Joseph. The course fully embraced problem-based learning (PBL), project-based learning, and service-learning strategies. It provided a service to the campus community through the task of creating a management plan for…

Research shows that keeping animals in classrooms can have profound effects on student well-being and success. With this practical guide, you will discover how to select a classroom pet, introduce it to students, and design carefully thought-out lessons centered around the animal.

Undergraduate biology education has changed over the past decade, incorporating an iterative and evidence-based approach. Many educational assessments have confirmed the effectiveness of integrating authentic research and open-ended inquiry into introductory biology courses, demonstrating a significant positive impact on students' learning and…

Understanding natural selection and adaptation are important precursors to learning evolution (NGSS Lead States 2013), the central unifying principle of biology. This lesson sequence, guided by the Five Practices Model (Cartier et al. 2013), incorporates data described by Andersson (1982) that details female choice in a population that eventually…

As a foundational evolutionary concept, the Hardy-Weinberg principle should be taught enthusiastically in introductory biology courses. In a companion Perspectives paper, I made the case that students are often given limited or incorrect information on the HW principle due to a lack of mastery or confidence on the part of their teachers. The…

The primary learning objectives of this "Next Generation Science Standards" (NGSS; NGSS Lead States 2013) aligned activity is to help high school biology students experience firsthand the role of replication in scientific inquiry and food preference as a behavioral reproductive trait of the Madagascar hissing cockroach. The secondary…

The discovery of and research into penicillin resistance by Sir Edward Abraham and Sir Ernst Chain can be used to teach the concept of natural selection and also multiple nature of science (NOS) objectives associated with Next Generation Science Standards, such as "scientific knowledge is based on empirical evidence" and "science is…

Laboratory exercises for undergraduate biochemistry students are described in which changes in sugar content during fermentation of the trendy beverage kombucha are analyzed by three methods: thin layer chromatography, a 3,5-dinitrosalicylic acid assay, and a standard commercial blood glucose meter. Each of the three analyses can be completed in a…

A lesson that focuses on the intricate co-evolution of flowers with their pollinators is one way to help students learn the delicate balance in nature and help ensure that our actions do not upset this balance. In this lesson students use the engineering design process to engineer a flower that is a perfect model for its chosen pollinator. Next,…

For many students, the first--and sometimes only--chance to look through a microscope is in high school biology class, where they observe plant and animal cells up close. Even in college, few students use a microscope for a subject other than biology. Thus, it can be a surprise to learn that microscopes are a primary tool used to understand the…

Are you interested in using argument-driven inquiry (ADI) for elementary instruction but just aren't sure how to do it? You aren't alone. "Argument-Driven Inquiry in Third-Grade Science" will provide you with both the information and instructional materials you need to start using this method right away. The book is a one-stop source of…
