In 3 experiments, the authors tested performance in simple tone matching and classification tasks. Each tone was defined on location and frequency dimensions. In the first 2 experiments, participants completed a same-different matching task on the basis of one of these dimensions while attempting to ignore irrelevant variation in the other…

The locust is well known for its ability to jump large distances to avoid predation. This class sets out a series of investigations into the mechanisms underlying the jump enabling students to bring together information from biomechanics, muscle physiology, and anatomy. The nature of the investigation allows it to be undertaken at a number of…

Since interest in science classes has declined recently and obesity, especially in youth, continues to increase, an exercise physiology-based course was taught in public parks to promote active-learning science and healthy living. The course emphasized and integrated exercise, nutrition, and health during a 3-h session. Following an introduction,…

Numerous brain areas work in concert to subserve memory, with distinct memory functions relying differentially on distinct brain areas. For example, semantic memory relies heavily on posterior cortical regions, episodic memory on hippocampal regions, and working memory on prefrontal cortical regions. This article reviews relevant findings from…

In this article, the author describes ways in which teachers can help children who exhibit problems in communicating due to language difficulties. In this particular case, the child described is very good at expressing herself, but does not seem to understand what others say to her, which limits her ability to follow directions and to interact…

The forebrain cholinergic neurons are localized in the nucleus basalis magnocellularis (NBM), the major source of cholinergic innervation to the neocortex and to the amygdala, and in the medium septum-banda diagonalis complex, which provides cholinergic inputs to the hippocampus (Mesulam et al. 1983; Woolf et al. 1984; Nicoll 1985). Basic and…

It is nearly impossible for a meaningful professional organization to exist and function effectively unless most of its members know something of its heritage, its history. The American Academy of Kinesiology and Physical Education (AAKPE) is exactly three-quarters of a century old. It is imperative for its members--Fellows--to know something of…

Background: Menstruation appears to be problematic for women with learning disabilities, yet there has been little quantitative research on their experiences, or comparisons with other groups of women. This paper considers the nature and extent of menstrual problems experienced by women with learning disabilities. Methods: The data reported here…

For some time it has been claimed that trisomic cells are more sensitive to oxidative stress since there is an imbalance in hydrogen peroxide metabolism due to an increase in superoxide dismutase (SOD) catalytic activity. We designed the present study to assess activity levels of antioxidant enzymes [superoxide dismutase (SOD), glutathione…

Background: It is known that women with Down syndrome can be fertile, but it is not known whether all women with Down syndrome are fertile or sub-fertile. The age at menopause for women with Down syndrome is lower compared to women without Down syndrome. Method: A cross-sectional study of 11 women was undertaken, in which the participating women…

Growing science apathy at the K-12 education level represents an alarming development with potentially devastating consequences at individual, societal and economic levels. Technology has been incorporated in science education without fundamentally improving test scores or student attitudes. We claim the core of the problem is how technology is…

This study investigates the cultural and educational ideas of the French deaf poet-teacher Pierre Pelissier (1814-1863) who was an instructor at the Paris Deaf Institute from the early 1840s until his death in 1863. As a young man, Pelissier became interested in composing poetry and through his verse, captured many of the social frustrations…

Self-inflicted injury in adolescence indicates significant emotional and psychological suffering. Although data on the etiology of self-injury are limited, current theories suggest that the emotional lability observed among self-injuring adolescents results from complex interactions between individual biological vulnerabilities and environmental…

Physiology education, which occupies an important place in undergraduate medical education, exhibits diversities across the world. Since there was no specific source of information about physiology education in Turkish medical faculties, the authors aimed to evaluate the general status of undergraduate physiology teaching of medical students in…

This mixed methods, exploratory study investigated the importance of the menstrual cycle diagram for understanding human reproduction. Several theories were used to support this study including Visual Design Theory (Tufte, 1990, 1997, 2001), and Human Constructivist Theory (Mintzes, Wandersee, Novak 1998). The two sexuality education programs used…
