Addresses, from a neurobiological perspective, the input-intake distinction commonly made in applied linguistics and the role of selective attention in transforming input to intake. The study places primary emphasis upon a neural structure (the nucleus reticularis thalami) that appears to be essential for selective attention. (79 references)…

This study documented the prevalence of exercise-induced asthma (EIA) in rural elementary schools, examining the use of a free-running asthma screening test and peak expiratory flow-rate measurement for school screening. Results indicated that 5.7% of the students had EIA. Absenteeism and poverty were related to EIA. (SM)

This article provides information from three areas critical to classroom success for mainstreamed hearing-impaired children: understanding hearing and the impact of hearing loss on classroom learning; promoting the use of signal-to-noise ratio enhancing equipment (typically Frequency Modulation units); and using educational management strategies…

Described are developments in medical electronics and physiological measurement. Discussed are electrocardiology, audiology, and urology as mature applications; applied potential tomography, magnetic stimulation of nerves, and laser Doppler flowmetry as new techniques; and optical sensors, ambulatory monitoring, and biosensors as future…

Community college anatomy and physiology students participated in a 14-hour study skills class designed to determine the effectiveness of a self-regulated strategy on immediate recall and retention of science knowledge. Results indicated that students who constructed graphic postorganizers recalled significantly more than students who simply…

Caregivers need to be alert to signs that a child is not hearing well so that children with hearing problems will receive prompt treatment. Explains the hearing process, what causes hearing loss, how to identify hearing loss at various stages of a child's development, and what caregivers can do if they suspect that a child has a hearing problem.…

A multimedia system for teaching physiology, using interactive video, introduced into the undergraduate veterinary curriculum at the University of Veterinary Science, Budapest, Hungary, was found to enhance creativity in learning. (AEF)

A study of 30 first-year medical students in a physiology course found that frequent evaluation had a profound negative effect on learning, with students adopting a surface reproductive approach geared to passing exams rather than integrating knowledge. Lectures and curriculum organization failed to affect student use and structure of knowledge.…

Discusses four chronic diseases (cystic fibrosis, congenital heart disease, rheumatoid arthritis, and asthma) that affect American children. Many have their physical activities unnecessarily restricted, though sports and exercise can actually alleviate symptoms and improve their psychosocial development. Physicians are encouraged to prescribe…

Describes a take-home experiment in which students measure the diffusion of acid through acid-filled capillary tubes immersed into base solutions and vice versa. Students represent and analyze the effects of ambient temperature, molecular weight, and concentrations of the solutions on that movement. (MDH)

Reports on a laboratory experiment where students measured their heart rate, blood pressure, mood, alertness, and cognitive performance. Measures showed significant circadian heart rhythm variations. They were strongly correlated and peaked at different times. Discusses the implications of this and students' reactions to the experiment. (MJP)

Describes one teacher's first attempt to understand the role of students' self-evaluations of their process and products in a science unit centered upon open-ended projects. Describes the social structure in student group self-evaluation, and explains the important role students' self-evaluations can play as part of an open-ended project learning…

We annotated transcripts of human tutoring dialogue for the purpose of constructing a dialogue-based intelligent tutoring system, CIRCSIM-Tutor. The tutors were professors of physiology who were also expert tutors. The students were 1st year medical students who communicated with the tutors using typed communication from separate rooms. The tutors…

Changes are occurring within Brazilian institutes of higher education; currently several universities are reviewing their course offerings and teaching approaches to determine if they meet the needs of today's undergraduate students. When changes are made to the curriculum of experimental courses, there should be an understood guarantee that all…

The National Inquiry Standard for Science Education Preparation requires science teachers to introduce students to scientific inquiry to solve problems by various methods, including active learning in a collaborative environment. In order for science teachers to comply with this inquiry standard, activities must be designed for students to…
