Describes some results of a project funded by the National Science Foundation to investigate ways to make a college biology course accessible to visually impaired students, including use of tactile diagrams as an alternative to microscopes and a variety of measuring techniques. (Author/SK)

Summarizes two research studies on: (1) suitability of science reading materials at CSE and O levels, and (2) effects of single sex and coeducation on science subject (N=1200) preferences and choices at 14+. Discusses spider diagrams, what is science, and problems and solutions in chemistry teaching in post-16 institutions. (DS)

Reviews developments in chemistry curriculum/instruction, providing lists of chemistry cassettes, monographs, educational literature from the Royal Society of Chemistry, new teaching packages, and course materials for science in society. Extends information presented in a previous article (EJ 235 051) appearing in this journal. (JN)

Following brief highlights of the development of organic chemistry, surveys undergraduate organic chemistry textbooks published in English since 1887 to see how the presentation of the subject has changed over the last 100 years. Coverage is restricted to texts designed for courses lasting one year or more. (Author/JN)

GEO-Study, an NSF-sponsored study, conducted by the American Geological Institute (1962-64) to examine the educational environment of 44 geology departments, initiating a change in United States geological education. Discusses the early years of development and study (emphasizing undergraduate geological education) and the last 10 years during…

Discusses dice model of exponential radionuclide decay; glancing and collinear perfectly elastic collisions; digital capacitance meter; use of top pan balance in physics; microcomputer calculation of gradient of straight line (includes complete Commodore PET computer program); Fresnel lenses; low-voltage radiant heater; Wheatssone's bridge used as…

Reliability, validity, and standards-setting procedure for a criterion-referenced test (Test of Metric Skills) were examined for use in science curricula. Results indicate a number of factors influencing test reliability/validity and that science teachers need to be aware of these factors to enhance accuracy of their judgments. (Author/JN)

Investigated is the effect of organization and accuracy of detail in instructional aids on the achievement of college students (N=54) in a freshman chemistry lecture course. It is indicated that aids may impede learning by decreasing students' involvement in auditory and semantic encoding during lectures. (Author/DS)

Reviews biology education from 1950 to the present and highlights major assessments of past efforts and current needs (emphasizing "critical elements" in biology curriculum/instruction noted in "Project Synthesis"). The historical perspective and data provided by the assessments are used to seek solutions for the remaining…

Provides evidence indicating that activity-based science programs substantially improve performance in science process/creativity; modestly increase performance on tests of logic, perception, language development, science content, and mathematics; modestly improve attitude toward science and science class; and have pronounced benefits for…

Presents a discussion of the need to present a realistic view of the process of science to students in the laboratory. Several activities and readings are suggested. (SA)

A laboratory exercise using a gerbil is described for use in the high school biology class and in accordance with the National Science Teachers Association guidelines. The authors cite references that deal with current awareness of the moral status concerning animals. The exercise includes measurement and calculations. (SA)

After describing a continuing education course in polymer chemistry, summarizes materials, methods, and results of an extensive evaluation of the course. Includes a discussion of benefits for participants and a list of 14 recommendations based on the evaluation. (JN)

Analyzes the current evolution/creationism controversy by reviewing court cases and what scientists and educators are doing to prevent creationism from being taught as science or included in school curricula. Includes viewpoints of scientists, educators, and creationists. (JN)

Discusses advantages of using an estuarine environment as a study area for A-level students and reviews organizational considerations. Details and references regarding a variety of suitable techniques are provided along with examples of results obtained by students at Waltham Forest College. (Author/DC)
