The procedures, data analysis, and applications of this laboratory activity are detailed. An example of the results obtained is provided. Sources of the tadpoles and their treatment are discussed. (CW)

Provides suggestions for a unit on the biological process of aging. Includes three activity sheets on the comparison of jaws and dentition from differently aged people, a denture survey, and eating and living without teeth. Includes a framework for organizing a course on the physiology of aging. (RT)

Describes 36 science activities. Topics include: osmosis, fermentation, anhydrobiotic organisms, breathing monitors, trypsin, weeds, amyloplasts, electrolysis, polarimeters, ethene ripening of fruit, colorimetry, diffusion, redox reactions, equilibria, acid-base relationships, electricity, power, resonance, measurement, parallax, amplifiers,…

Presents information on student interest, teaching problems, and learning outcomes regarding the use of cadavers as a teaching tool. Provides a list of Illinois Community Colleges using cadavers and a student questionnaire. (RT)

Investigates memory storage and molecular nature of associative-memory formation by analyzing Pavlovian conditioning in marine snails and rabbits. Presented is the design of a computer-based memory system (neural networks) using the rules acquired in the investigation. Reports that the artificial network recognized patterns well. (YP)

Described is a laboratory procedure for teaching seed stratification. Materials, methods, results, and applicability of the experiment are explained. Diagrams showing the percent of total germination as a function of stratification time and the germination rate of stratified seeds are included. (RT)

This interview with Jeffrey Borer, who directs cardiovascular research at Cornell Medical College, addresses his research interests, the status of research compared to practice, ways to meet educational needs of students with science talent, the role of contests and mentors, and the importance of exposing children to many types of learning…

Taught comparative animal physiology to undergraduates (n=31) using student-centered (open-ended) investigations in small groups. Questionnaires and discussion found that students appeared to value learning through their own experience as highly as they did being taught and valued the opportunity to establish and develop skills less easily…

This article introduces several papers which discuss chronic illnesses that are frequently associated with learning disabilities, noting the relationship between the disease's pathophysiology and learning disorders and, sometimes, between the treatment of the disease and learning effects. The four papers in the series in this issue are each…

For the primary eye care practitioner in the 1990s and beyond, the basic biomedical sciences have supplanted physiological optics as the primary academic discipline underlying the practice of optometry. Several curriculum development options are available to incorporate the needed material, but a core curriculum is essential at all institutions.…

Research indicates athletes may require more of certain nutrients than other healthy individuals. The article discusses vitamin requirements and deficiencies and how to supply the needed nutrients. Since coaches, trainers, and physical education teachers influence their athletes' behaviors, they must examine the issues associated with vitamin…

A computer program that replaces a set of pharmacology and physiology laboratory experiments on live animals or isolated organs is described and illustrated. Five experiments are simulated: dose-effect relationships on smooth muscle, blood pressure and catecholamines, neuromuscular signal transmission, acetylcholine and the circulation, and…

An approach to teaching electrochemical driving force that helps students comprehend the forces that govern ion flux across biological membranes and sets the stage for more elaborate analysis of biochemical signals is presented. Background information and two sample problems and answers are included. (KR)

Discusses an evolutionary approach to human morality. Emphasizes the rapid development of brain weight, neural circuits, and synaptic systems during early childhood. Concludes that the human brain has resources for generating responsible, caring behavior but must be nurtured and educated. Urges that moral training in a proper social climate be…

Described is a summer workshop for college and high school educators designed to raise the level of expertise of the participants and to raise their awareness of physiology and medical opportunities for their students. The objectives, organization, schedule, content, credit, financial considerations, and evaluation of the program are discussed.…
