Describes an undergraduate field program, developed over a period of five years at Iowa State University, which provides a combination of field experience and an opportunity for the prospective teacher to work with secondary school students in the field for a one-week period. (PR)

Identifies various components of scientific literacy and characteristics of scientifically literate people. Discusses factors inhibiting scientific literacy. Suggested remedies: federal support for special programs, redesign of teacher education programs and science content courses at all levels, and setting up means of interpreting science to the…

Suggests uses for and possible adaptations of a set of semiflexible molecular models. Includes price and supplier information. Also suggests rubbing oil from human face/hands along the pouring lip of a beaker, allowing one to pour uniformly from the beaker spout and making the process as dripless as possible. (Author/JN)

Highlights major accomplishments, developments, and research in the sciences during 1982, focusing on the space sciences, astronomy, medicine, biology, psychology, chemistry, physics, environment, and zoology. Includes a brief statement of the 1982 Nobel Prize winners' research in medicine, chemistry, and physics. (JN)

Using percolating filters (components of sewage treatment process) reduces problems of organization, avoids damage to habitats, and provides a local study site for field work or rapid collection of biological material throughout the year. Component organisms are easily identified and the habitat can be studied as a simple or complex system.…

Reviews filmstrip/cassette recording materials titled "Reaction Rates: Molecules in Motion." Also reviews six college-level textbooks, addressing major strengths/weaknesses of texts under consideration with regard to their specific usefulness to high school chemistry teachers. (JN)

Reviews two textbooks: "Principles of Biochemistry" by Albert L. Lehninger and "Inorganic Chemistry, A Modern Introduction" by Therald Moeller. Also reviews text, study guide, and laboratory manual for Morris Hein's "Foundations of College Chemistry, Fifth Edition" and text/study guide for David A. Ucko's "Basics for Chemistry." (JN)

Presents information relevant to everyday life so as to stimulate student interest in the properties of the two basic types of liquid crystals: thermotropic and lyotropic. Describes the applications of liquid crystals to electronics, biomedicine, and polymer science and appraises the future of liquid crystal research. (JM)

Examines current status of college science education in light of recent calls for reintroduction of science into liberal arts curriculum, presenting a course sequence as basis for discussion. Proposes advantages of and need for a committee to monitor courses in the sequence. Also lists advantages of increased exposure to science. (JM)

Presents findings from research studies which suggest that changes in teaching procedures can increase survival rates in chemistry. Using 2-minute pauses in lecture and 3-second wait times in discussions, learning chemistry in context of major from which student comes, and computer applications are recommended. (JN)

Discusses faculty and student contributions to student academic failure, suggesting changes in the chemistry curriculum to accommodate increased numbers of non-traditional students. Also suggests creating compensatory programs, leaving content and teaching system intact for traditional students. Factors in developing such programs are considered.…

Outlines procedures demonstrating that the aperture of a microscope objective limits resolving power and then, by using ancillary measurements made with a calibrated graticule in the microscope eyepiece, that the experimentally determined value for the maximum resolving power of a given objective is close to the value predicted by theory. (JN)

Reviews software package for college advanced high school physics. The package, for Apple microcomputers, contains programs instructing students on how to analyze motion of objects under a variety of circumstances. Programs include graphing motion, one-dimensional kinematics, gravity problems, projectile, dynamics (general method), motion on…
