Reviews the work of the Commission on Undergraduate Education in the Biological Sciences (CUEBS) from 1964 to 1972. Suggests that now is the appropriate time to reassess their efforts, to build on their successes, and to use their experience to attack some of the continuing problems facing biology education.

Uses air temperature profiles--a topic taught in beginning meteorology courses--to illustrate the ease of restructuring the teaching/learning environment as a problem-solving mode. Students access real-time information through Accu-Weather's interactive database. Students use the data to answer the question, "What happens to air temperatures…

Eighth graders' ideas about thermodynamics, and their understanding of thermodynamics principles, were assessed before and after they attended a one-semester course on thermodynamics. Results characterized students' views concerning scientific explanations of phenomena, parsimonious versus descriptive explanations, the application of science…

In this article, implications for policy, development, and implementation of educational change are offered, along with suggested directions for research. The author contends that all involved need to work together; they need to develop a holistic view of the system and work with an approach that engages interactive partners in the educational…

A study of English students' concepts of pollution (n=122) indicates students understand pollution in two distinct ways: pollution that goes into the atmosphere and pollution that damages or destroys. Concludes that to the students' minds it seems that both these definitions can only be valid if associated with human-made activities. (Author/MCO)

The redesign of basic science curriculum at the Columbia University (New York) dental school is outlined. Goals included development of a medical continuum allowing students to apply basic science to patient care; decompression of crowded second-year content; and facilitation of student pursuit of research and other biomedical interests in third…

Compares current science education reform efforts with those of the 1960s to enhance student learning. Discusses how an "alternative models" view of scientific explanation can contribute to reforms of course goals, social aspects of science learning, instructional practices, and roles for technology. Contains 50 references. (ZWH)

The lack of a vision of sustainability in contemporary science education is discussed. Policies for curriculum and instruction that will enhance sustainable growth that are based on the ideas of fulfilling basic human needs, improving the environment, conserving resources, and developing a sense of community are presented.

Describes assignments in abstract writing as well-suited way to integrate writing into curriculum of large introductory geology courses. When students write abstracts on either assigned outside readings or special sections in their textbooks, they develop a concise writing style and polish their writing skills and also increase their understanding…

Authors describe a "writing intensive" physical geology course utilizing both formal and informal writing assignments. The formal assignment consists of a summary paper on four geological articles. A writing tutor provides feedback on drafts of the summaries. The informal writing assignment requires students to keep a journal related to laboratory…

Author describes her first-year seminar in history of geology where students are given writing assignments asking them to summarize, describe, explain, be convincing to reader. Students review their written work through frequent revision, peer review, collaborative writing assignments. Assignments require students to examine scientific principles…

Describes advantages and details of use of journal writing in introductory geology course. Entries include minimum of three one-page entries per week and count for 25 percent of course grade. Most students start with restatement of ideas presented in class; by end of the course, they are drawing original conclusions and applying ideas in new…

Describes a method of teaching geology and scientific writing to nonscience students that combines active integration of lecture, reading, and laboratory materials with field observations into a writing assignment on a real scientific problem. The writing assignment is completed in stages: a prospectus, a detailed report outline, a bibliography, a…

Describes an assignment in a paleontology course built around constructional morphology and the role of adaptation and exaptation in evolution. Students investigate the constructional morphology of a group of fossils that interests them. Findings are presented in an oral presentation and in a term paper. (27 references) (PR)
