Described are the advantages of using crayfish in an elementary or secondary biology class, crayfish activities, field collection, classroom care, and identification. (DC)

Highlights scientific accomplishments in 1981. Focuses on space sciences, medicine, geology, chemistry, physics, zoology, paleontology, environmental problems, and genetics including such topics as the Space Shuttle, Mount St. Helen's endangered species, genetic engineering, and the scientists associated with these accomplishments. (JN)

Presents content information and/or laboratory procedures and experiments on different biology topics including small-scale cultivation of watercress and its use in water-culture experiments, microbiology of the phylloplane, use of mouthbrooders in science class, and the gene. (DC)

Described is a procedure for assessment of student performance in laboratory work (practical work) in Advanced Level Biology in England. Some historical background is included. (PB)

Examined are social factors that influence biological science knowledge content in terms of these paradigm shifts: the DNA revolution, the Continental Drift revolution, the Darwinian revolution, and the sociobiology revolution, with the term "revolution" being used in the sense of Thomas S. Kuhn's writings. (PB)

Examined is the issue concerning teaching bioethics. Differing points of view are discussed. The author concludes that moral and ethical reasoning should be incorporated into the public school curriculum, using morally laden issues that have grown out of advances in biological knowledge and biomedical technology. (CS)

Described is a case study used in an introductory college biology course that provides a basis for generating debate on an issue concerning the regulation of controversial food additives and prescription drugs. The case study contained within this article deals with drug screening, specifically with information related to thalidomide. (CS)

An empirical enquiry into the nature of academic disciplines is described. The main similarities and differences of six academic disciplines--physics, history, biology, sociology, mechanical engineering and law--are outlined. Different research styles are identified and characterized as urban and rural research styles. (Author/MLW)

Examines microwave and radio wave radiation in terms of government regulations, harmful effects, existing studies, definitions, and the need for further research. (DS)

The creation/evolution controversy has gained renewed popularity in the last few years. This has resulted in serious implications for science teachers. All classroom teachers need to protect themselves by learning the distinctions between scientific law and theory and to acquire knowledge of the various theories of evolution. (JN)

The analysis of data from a survey of lecturers and students in 13 universities/university colleges, together with evidence from other independent sources, shows that the introduction in the sixth form of a common core biology syllabus with specialist options is desirable. (Author/MA)

A questionnaire was administered to first-year biology, physics and chemistry students in an Israeli university to assess their views on the nature of the contribution made by their high school courses to college achievement. Results indicate that high school curriculum influences attitudes, knowledge retention, expectations, and achievement in…

Reports results of a study testing a selective attentional model which predicted that textbook study questions adjunct to a flow diagram will focus students' attention more upon questioned information and less upon nonquestioned information. A picture-word diagram describing biogeochemical cycles to high school biology students (N=176) was used.…

Provides results of a comparative study of differences between Israeli (N=628) and U.S. (N=302) students in their perceptions of science classroom behavior. Dependent variables were a role-specific self-concept score and rank orders of behavior statement items, and independent variables were country of student and grade level. (CS)

Cites numerous examples used by a pro-evolutionist in debate with the creationists associated with the Institute for Creation Research and the Creation Research Society. (CS)
