A group of Maine birdwatchers recognizes that the presence or absence of migrating songbirds is related to complex biospheric patterns. For schoolchildren, community groups, and environmental scientists, such local natural history observations can be a pathway to perceiving and understanding global ecological change and then to developing…

According to the National Science Education Standards (National Research Council 1996), students in the middle school years should progress in studying life science from examining individual organisms to recognizing patterns in ecosystems and developing an understanding about the cellular dimensions of living systems. Students should broaden the…

Choices in science--allocation of research funds, selection of research topics, interaction with research subjects (animals, environment, other humans), etc.--often, if not always, include some ethical considerations. Future scientists need skills to deal with and discuss ethical problems, and for that reason we have developed and evaluated one…

This report provides an overview of the efforts of Iowa's community colleges to train workers for the emerging bioscience/biotechnology sector. The report explains the programs available and the future plans of individual community colleges designed to educate students for careers in the biosciences. Also detailed are a variety of creative…

Over the past decade, much has been learned about the ocean's secrets and especially about the creatures of the deep sea. The deepest parts of the oceans are currently the focus of many new discoveries in both the physical and biological sciences. Middle school students find the deep sea fascinating and especially seem to enjoy its mysterious and…

This annual report of the Assembly of Life Sciences (ALS) covers the fiscal year from July 1, 1978 to June 30, 1979. The report has four major sections: (1) Special Programs of the Executive Office; (2) Division of Biological Sciences; (3) Division of Medical Sciences; and (4) Board on Toxicology and Environmental Health Hazards. The activities…

Describes the origins, definitions, tools, and principles of host-guest chemistry. Gives examples of chiral recognition in complexation, of partial transacylase mimics, of caviplexes, and of a synthetic molecular cell. (Author/RT)

Students become motivated to learn life science concepts when they see how this knowledge can help in resolving personal needs and societal issues. Teacher education programs must prepare both preservice and inservice teachers to teach science concepts in practical ways. (DF)

Reviews effects of hormones, systemic factors, and local regulators on bone formation. Identifies and explains the impact on bone growth of several hormones as well as the components of systemic and local systems. Concentrates on bone collagen and DNA synthesis. (Physicians may earn continuing education credit by completing an appended test). (ML)

Advocates using slides to supplement classroom instruction in many ways: introducing a concept; teaching a skill; reviewing for an examination; developing critical thinking; and instilling values. Slides of pictures in books, magazines, and newspapers can also prove useful in lessons when firsthand experience is not possible. (DH)

Describes elements in a course based on formulating principles and basic quantitative hypotheses directly in a programing language, thereby bypassing the language of mathematics. The course is designed to enable mathematically shy students to gain understanding of quantitative methods. Three computer programs are described in detail to illustrate…

Summarizes the views of Ernst Mayr on the controversy over evolution which exists between physical scientists and biologists. Discusses the uniqueness of individuals, work by population geneticists and mathematical geneticists, complexity in nature, rates of change, modes of change, and the need to ask "why". (DC)

Recommendations are made for handling and growth of Beneckea natriegens, a rapidly growing, nonpathogenic marine bacterium which can be used with advantage to replace Escherichia coli in many undergraduate microbiology experiments. Examples of experiments and the potential value of this organism as a subject for student research projects are…

A volunteer for an Earthwatch research project describes experiences in Nepal. (JD)

Proposes a design for a life science curriculum following the National Research Council National Science Education Standards. The overarching theme is that science as inquiry should be recognized as a basic and controlling principle in the ultimate organization and experiences in students' science education. Six-week units include Matter, Energy,…
