Examined alternative conceptions of animals and animal classification by interviewing fifth grade, eighth grade, and freshmen/sophmore college students (N=62). Subjects were asked to name five animals, state critical attributes, and complete a classification task. Results indicate all ages fail to generalize and discriminate among examples and…

Highlights findings, conclusions, and recommendations from a 3-year study of academic laboratory equipment conducted by three university associations. Although ultimately the problem's solution will require increases in funding, several actions (which are described) could be taken to improve the efficiency of acquisition, management, and use of…

Liberal arts graduates should be educated in these aspects of science: hypothesis and experimentation as the basis of scientific thought, problems of translating scientific thought into economic and social benefits, concepts of probability and uncertainty, and conflicts in scientific, technological, and public policy goals. (MSE)

Two common challenges in teaching large lecture courses are student anonymity and student heterogeneity., An innovative approach to meeting these challenges was implemented in a human physiology course at the University of Nebraska-Lincoln. The use of an automatic telephone answering machine is described. (MLW)

Presents a theoretical framework for and a detaled description of a model for teaching scientific analogies. The framework focuses on the definition of an analogy, analogical learning, variables related to analogical learning, evaluating outcomes of analogical limiting, and limitations of using analogies in teaching. (JN)

The "Research Vessel Westward" provides a sea-going research laboratory for students from various disciplines to learn oceanography concepts and research techniques while earning university credit. Descriptions of equipment, organizational structure, and student research responsibilities are presented. (DH)

A seminar which uses a case history approach and the Socratic method to evaluate legal aspects of geology is described. Water rights law, mineral law, and legal aspects of landslides, subsidence, sedimentation, erosion, and submergence are discussed. Students deal with hypothetical problems and participate in group projects related to these areas.…

Discussion of changes in science education and scientific literacy is presented in the form of a dialog between the author and his alter ego. Structure of science, myths, facts, methods, and critical rationality are considered. Suggests that scientific principles once considered basic and unchanging are giving way to critical thinking. (DH)

Student interest was stimulated and critical thinking skills developed through an "Issues in Social Biology" course which include several topics in genetics. Judicious selection of topics, course format, and ordering of subjects are discussed, along with suggestions for course improvement development. (DH)

Presents a collection of articles to provide chemistry teachers with resource materials to add forensic chemistry units to their chemistry courses. Topics range from development of forensic science laboratory courses and mock-crime scenes to forensic serology and analytical techniques. (JN)

Defines "real world" examples providing rationale for incorporating them into chemistry teaching. Topic areas of papers include: chemistry in a watershed, polychlorinated biphenyl (PCB), consumer chemistry, culinary chemistry, using real world examples in a laboratory program, projects relating real world chemistry to high school…

Compares safety in the chemical industry to academic chemistry laboratories based on the incidence rate for minor industrial injuries compiled by the U.S. Department of Labor, Bureau of Labor Statistics and the author's estimate of academic rates. Provides a list of over 50 errors and omissions commonly found in chemical laboratories. (JM)

Describes several methods of executing lecture demonstrations involving the recombination of the spectrum. Groups the techniques into two general classes: bringing selected portions of the spectrum together using lenses or mirrors and blurring the colors by rapid movement or foreshortening. (JM)

Describes safety practices for laboratory fume hoods based on certain assumptions of hood design and performance. Also discusses the procedures in preparing to work at a hood. A checklist of good hood practices is included. (JM)

Provides information based on explorations of the Apollo program about the geochemistry of the moon and its importance in developing an understanding of formation/evolution of the solar system. Includes description and some results of orbital remote sensing, lunar x-ray experiments, gamma-ray experiments, alpha-particle experiments, and the Apollo…
