When students think of evolution, they might imagine T. rex, or perhaps an abiotic scene of sizzling electrical storms and harsh reducing atmospheres, an Earth that looks like a lunar landscape. Natural selection automatically elicits responses that include "survival of the fittest," and "descent with modification," and with…

Biological systems exhibit strong dynamic variations; for example, a system may have a tendency towards either a steady state, periodic behaviour or chaotic oscillations. These findings, explained by dynamic systems theory, have allowed researchers to formally relate a wide variety of systems, such as the theory of rumour propagation, glucose…

These three biology songs can be used for educational purposes to teach about biochemical concepts. They touch on three different topics: (1) cancer progression and germ cells, (2) gene expression, promoters, and repressors, and (3) electronegativity and the biochemical basis of photosynthesis.

Laboratory courses should cultivate enthusiasm for research and an appreciation for real-world scientific challenges to retain undergraduate students and encourage them to pursue STEM-related careers. Course-based undergraduate research experiences (CURE) have emerged as an inclusive pedagogical model that facilitates laboratory skill development,…

This work presents a three-dimensional (3D) modeling exercise for undergraduate students in chemistry and health sciences disciplines, focusing on a protein-group linked to immune system regulation. Specifically, the exercise involves molecular modeling and structural analysis of tumor necrosis factor (TNF) proteins, both wild type and mutant. The…

A modified total synthesis of (S)-goniothalamin is described for an advanced course in organic chemistry. This experiment gives students an opportunity to handle organometallic reagents and perform an enzymatic kinetic resolution and a metathesis reaction, all in the same synthesis. Furthermore, students learn flame-drying techniques for the…

The increase of chronic disease in the United States has created a strong demand for health education specialists (HESs) who are trained to facilitate behavioral, environmental and policy changes through program implementation and evaluation. However, it is difficult for colleges and universities to prepare future health educators to be competent…

This classroom note illustrates how dynamic visualization can be used to teach conditional probability and Bayes' theorem. There are two features of the visualization that make it an ideal pedagogical tool in probability instruction. The first feature is the use of area-proportional Venn diagrams that, along with showing qualitative relationships,…

A visitor to Peter Green Hall Children's Centre's classroom for 4- and 5-year-olds broke down in tears when she saw their teacher Bobbi with a head bald from chemotherapy. The visitor said her sister-in-law had recently died of breast cancer. In the family's desperate need to cope with the situation, their children, 4 and 6 years old, were not…

We developed an interactive laboratory that allows students to identify and grade tissue samples from human breast biopsies, using techniques similar to those used by actual pathologists. This unique lab develops a practical and intellectual understanding of basic tissue structures that make up living systems, utilizing technology to bring…

It is frequently said that a good teacher will spice up their lessons with anecdotes and stories associated with the subject as these help to bring the subject alive. This is true in teaching radioactivity but it is not always easy to find a useful fund of stories--especially for a non-specialist. Paula Kennedy shares the stories and anecdotes…

This installation is a personal and cathartic engagement with my initial inability to cope with my daughter's cancer. It details events that began in August of 2008 and concluded, in a sense, in February of 2009. I offer it with hopes of helping digitally-oriented rhetoric and composition scholars "determin[e] a should for a we" (Patricia Sullivan…

Most general biochemistry textbooks present enzyme inhibition by showing how the basic Michaelis-Menten parameters K[subscript m] and V[subscript max] are affected mathematically by a particular type of inhibitor. This approach, while mathematically rigorous, does not lend itself to understanding how inhibition patterns are used to determine the…

Recently there have been several news items about possible cancer clusters in the Australian media. The term "cancer cluster" is used when an unusually large number of people in one geographic area, often a workplace, are diagnosed with cancer in a short space of time. In this paper the authors explore this important health issue using…

Students learning statistics want to know how our methods are used in the real world. In response, this article offers a discussion of a relevant and timely medical study reported in recent headlines. Careful consideration of the study raises some ideas to get students engaged with statistics.
