This article contends that instructional designers and developers should attend to four particular design principles when creating instructional audio. Support for this view is presented by referencing the limited research that has been done in this area, and by indicating how and why each of the four principles is important to the design process.…

Sleep-wake behavior, as well as sleepiness, is regulated by the joint action of an exponentially increasing drive for sleep--sleep homeostasis--and by variations in sleep propensity due to a biological circadian oscillator. However, large inter-individual differences remain. Short and long sleepers have been known to differ in the amount of…

The aim of this study was to investigate whether the preschool activities challenge the stress regulative system in children. We used a multi-system approach to evaluate the underlying processes of stress responses and measured both cortisol and [alpha]-amylase responses after emotionally and cognitively challenging tasks followed by a recovery…

Hip fracture is considered one of the most fatal fractures for elderly people, resulting in increased morbidity and mortality and impaired functional capacity, particularly for basic and instrumental activities of daily living. The aim of this study was to determine the effect of implementing a discharge plan on functional abilities of geriatric…

Anatomy and physiology teaching has undergone significant changes to keep up with advances in technology and to cater for a wide array of student specific learning approaches. This paper examines perceptions towards a variety of teaching instruments, techniques, and innovations used in the delivery and teaching of anatomy and physiology for health…

For the better part of the past century, the field of education has witnessed repeated calls and initiatives for change, reform and improvement of our schools. Yet today, the problems of improving academic achievement and social adjustment among youth continue unabated. An explanation for this "change without change" phenomenon is…

Investments in the select few who already are or will become academic leaders are essential but insufficient. Investments also need to be made in collective leadership because leadership is an activity or function, not merely a person. Both good leaders and collective leadership are needed in the never-ending journey toward selective excellence. A…

The administration and community used to place little or no value on physical education and attendance, and attitudes toward our profession were stereotypical and disrespectful. Yet, at some level, there were people quietly longing for a change. This article describes how the author used her passion for yoga to win over her students and,…

An understanding of body composition is crucial to understanding human health, disease, and function. Research in body composition has focused on the development of assessment methods, description of normal changes in body composition with growth and development and aging, and the changes that occur in body composition in response to challenges…

Due to the growing incidence of diabetes in developed nations, there is a compelling case to be made for teaching graduate students more deeply about mechanisms underlying this disease. Diabetes is associated with enhanced oxidative stress and protein glycation via the covalent binding of glucose molecules. Albumin represents the major plasmatic…

The combination of the process of pedagogical planning within the Blended (b-) learning environment with the users' quality of interaction ("QoI") with the Learning Management System (LMS) is explored here. The required "QoI" (both for professors and students) is estimated by adopting a fuzzy logic-based modeling approach,…

In the present article, a novel model of artificial membranes that provides efficient assistance in teaching the origins of diffusion potentials is proposed. These membranes are made of polycarbonate filters fixed to 12-mm plastic rings and then saturated with a mixture of creosol and "n"-decane. The electrical resistance and potential…

This article describes a lesson on bats developed for kindergartners, which uses models of bats to teach about their physiology, diet, and habitat. The lesson uses craft sticks, wax paper, and colored construction paper that kindergarten teachers can use to help their students compare the features of 4 different kinds of bats. The use of online…

This article presents a case study regarding healthy weight loss and the role of the hormone ghrelin in maintaining a lower body weight. This study was designed specifically for use in an introductory college-level physiology course. It addresses the use of the case study in teaching digestion and metabolism, exploring the role of hormones in…

In the late 1980s and early 1990s, the time spent in moderate-to-vigorous physical activity (MVPA) during physical education class time started to be measured and questioned (Bar-Or, 1987; Lacey & LaMaster, 1990; McGing, 1989; Simons-Morton, Taylor, Snider, & Huang, 1993). Researchers suggested that the amount of time students spent in…
