Describes how a college teacher used Navajo traditional knowledge to rethink the teaching of college biology. Suggests that teachers intimidated by the intricate Dine Philosophy of Education may integrate Navajo knowledge into their courses through focused research guided by Navajo consultants. Includes five examples of redesigned curricula for…

Presents an activity integrating mathematics and science intended to introduce students to the use of metric measurement of mass as a way to increase the meaningfulness of observations about variables in life sciences. Involves measuring the nutrient tolerance of algae. Contains a reproducible algae nutrient graph. (Author/MKR)

Sixty-seven students participated in a study that used path analysis techniques to test a hypothesized structural model of direct and indirect causal effects of students variables on science process skills. Academic ability, biology knowledge, and language preference were found to have significant direct effect, whereas cognitive development,…

Describes a learning-cycle approach to teach a lesson exploring the biotic potential of plants. Discusses the phases of learning: exploration, concept invention, and application. Lists five resources. (JRH)

Describes activities for biology teachers that will stimulate discussions on virus structure, cell biology, rhino viruses, and new trends in treating the common cold. Provides opportunity for inquiry and problem solving in exercises that emphasize an understanding of how common cold viruses might pack inside nasal epithelial cells. (14 references)…

The effects of a visual advance organizer on a biology concept learning task among fifth graders (n=48) was investigated. After exposure to the advance organizer, three levels of learning outcomes-knowledge, comprehension, and application-were evaluated. Findings of the study are discussed in terms of the assimilation theory, aptitude-treatment…

Describes the biological basis of learning and individuality. Presents an overview of recent discoveries that suggest learning engages a simple set of rules that modify the strength of connection between neurons in the brain. The changes are cited as playing an important role in making each individual unique. (MCO)

Describes responses by biology Presidential Science awardees to survey of their professional journal reading. Slightly more than 70 percent read part of each issue of "American Biology Teacher" and "Science Teacher." Other well read journals include "National Geographic,""Discover," and "Science…

A study using national data investigated extension of the social control theory of deviance to deviance from the four Mertonian norms of science among faculty in seven disciplines. Results suggest social control in the academic profession lies primarily in the community of the academic disciplines rather than with personal controls. (Author/MSE)

Presents race concept as an example of how social issues are underemphasized in college science education. Reviews history of the race concept and reports on current status of the concept in textbooks and among college faculty members. Given specific stipulations, proposes continued use of the race concept for some infrahuman species, while…

This college Life Science lecturer describes health-related videos she has integrated into her curriculum. She provides the names of specific videos for the following topics: AIDS, cocaine, alcohol, nutrition, smoking, and stress. Instructional strategies for the use of specific videos and general strategies for implementing a video approach are…

Authors describe how to use videodisks and computer software in biology instruction. HyperCard Videodisc Toolkit for the Macintosh computer and the BioSci videodisc are used to explain basic principles in the preparation of multimedia presentations. Authors assert that the use of this technology enhances student learning by inserting excellent…

The value and difficulties of long-term ecological monitoring studies undertaken in schools and colleges are reviewed. Rookeries, stream ecology, sand dune succession, fish population, and seed production and survival are presented as examples of successful studies. This is followed by a discussion of points to consider when setting up a long-term…

Identifies specific instruction difficulties, potential problems, solutions, and activities for successful use of microscopes in the classroom. Procedures are outlined for guiding students in creating their own slides with monocotyledon and dicotyledon stems, fern spores, stomata, lichens, and red onions. (MCO)

Many assert that the use of animals for dissections in the secondary and undergraduate class is unnecessary. This article describes a study conducted to compare the attitudes and achievement of students who use interactive methods instead of conventional dissection. (ZWH)
