Although integrating the history of science (HOS) into teaching has long been recommended in science education research, studies have revealed conflicting results on its effectiveness. These are mainly due to the need for more studies in this context. Therefore, this research aimed to explore the impact of HOS teaching on science process skills,…

Thermoregulation is the maintenance of a relatively constant core body temperature. Humans normally maintain a body temperature at 37°C, and maintenance of this relatively high temperature is critical to human survival. This concept is so important that control of thermoregulation is often the principal example cited when teaching physiological…

There has been much recent commentary on integration in health care professional education. This commentary is of importance to physiology education as integration often touches on integration between preclinical and clinical sciences. There are different forms of integration, from horizontal to vertical to spiral, and different theories underpin…

"Virtual Clinical Trials" simulations were designed to highlight neuroscience research and reinforce experimental design through the recreation of published clinical trials. This paper reports the effectiveness of "Virtual Clinical Trials" simulations in improving knowledge of concepts related to the experimental design process…

Using Pompe disease as a context affords the opportunity for students to consider multiple biological concepts and embraces the Next Generation Science Standards Disciplinary Core Ideas Structure and Function (LS1.A) and Inheritance of Traits (LS3.A) as well as Crosscutting Concepts Structure and Function and Cause and Effect. These crosscutting…

The laboratory has been given a central role in physiology education, and teachers report that it is motivating for students to undertake experimental work on live animals or measuring physiological responses on the students themselves. Since motivation is a critical variable for academic learning and achievement, then we must concern ourselves…

The major challenge in laboratory teaching is the application of abstract concepts in simple and direct practical lessons. However, students rarely have the opportunity to participate in a laboratory that combines practical learning with a realistic research experience. In the Bioengineering Department, we started an experiential laboratory…

Protein kinase Cs (PKCs) are implicated in many forms of synaptic plasticity. However, the specific isoform(s) of PKC that underlie(s) these events are often not known. We have used "Aplysia" as a model system in order to investigate the isoform specificity of PKC actions due to the presence of fewer isoforms and a large number of documented…

Explains the mechanisms and describes the processes that underlie gravitropism in roots. Reviews experimental efforts and investigative results that explored the causes of root behavior. (ML)

Examines research related to the retina's coding of visual input with emphasis on the organization of two kinds of ganglion cell receptive fields. Reviews current techniques for examining the shapes and arrangement in the retina of entire populations of nerve cells. (ML)

In this study the photoinhibition of photosystems (PS) I and II caused by exposure to high intensity light in oat ("Avena sativa," var Prevision) is measured by the emission of chlorophyll fluorescence in intact leaves adapted to darkness. The maximal quantum yield of PS II was lower in plants grown under high light intensity than in plants grown…

Presents the mathematics of body size and surface area to volume. Examines arguments used related to the topic. Concludes that while some of the traditional arguments are valid, most are not. One analysis for an organism is provided in an appendix. (YP)
