Reports on the method and findings of a study which used unobtrusive testing to measure the accuracy and efficiency of search strategies by library personnel when dealing with the technical report literature. A copy of the test questions used in this study is appended. (CLB)

Discusses the various ways that time is measured and expressed, noting several discrepancies between descriptives and their respective vocabularies. Suggests that a logarithmic time scale be adopted by chemists (such as one used in the experimental sciences) particularly when addressing very fast processes. (TW)

Discusses the historical development of a new value of the second dissociation constant (K2) for hydrogen sulfide (H2S). Describes the differences between the traditional high values for K2. Suggests modification of teaching about sulfide equilibria in light of the new low value for K2. (TW)

Provides a review of important science news stories as reported in the issues of "Science News." The stories are summarized under 13 headings and include references to the volume and page number in which the subject appeared. (ML)

Describes an approach to problem solving based on real-world problems. Discusses problem analysis and definitions, preparation of briefing documents, solution finding techniques (brainstorming and synectics), solution evaluation and judgment, and implementation. (JM)

This paper argues that science can be defined with sufficient clarity so as to maintain a coherent boundary for the practical purposes of school science curriculum development. That boundary excludes most forms of indigenous knowledge, if not all, just as it excludes art, history, economics, religion, and many other domains of knowledge. Being…

A citation analysis was conducted to assess the impact of electronic journals on scholarly communities and their research. The article discusses data collection methods (the Institute of Scientific Information's indexes, searchable via DIALOG), explains searches done on particular record fields, and identifies the most frequently cited electronic…

Provides a background of the National Science Foundation's NSDL (National Science, Technology, Engineering, and Mathematics Education Digital Library) which includes three tracks: collections, services, and targeted research. Discusses challenges and opportunities for elementary and secondary school library media specialists and teachers. (LRW)

Discusses access to information concerning environmental issues in Canada and the United States. Highlights include the cross-disciplinary nature of the field; sources of environmental information, including scientific and corporate sources and reviews; government literature; the Canadian Access to Information Act; electronic databases; and the…

To be effective in promoting scientific literacy, science teachers must be well prepared in their subject areas, have a firm understanding of the nature of science, and stay abreast of current technological advances affecting society. Science teachers must engage students in the science revolution by relating it to their lives. (AF)

Reports on a study, Science for All Americans, by the AAAS. Notes this study is the first of three phases in Project 2061. Recommends science teaching should focus on connections rather than boundaries between traditional academic disciplines and should emphasize ideas and thinking rather than specialized vocabulary and memorized procedures. (MVL)

Ten science textbooks (4,393 pages) for grades 6 and 7 were examined for their treatment of five top-ranked global problem issues (population growth, war technology, world hunger and food resources, air quality and atmosphere, and water resources). Implications for science education curricula from this content analysis are discussed. (SLD)

Summarizes the development of scientific and technological libraries and document centers in Bangladesh and describes the problems of acquiring scientific literature through purchase, gift, and exchange programs. The effectiveness of cooperative acquisition programs and international sources of document supply are examined, and plans for future…

Describes recent progress in China in the publication of scientific and technical journals and the computerization of information services; assesses the output of scientific and technical papers and the extent to which they are indexed by foreign bibliographical sources; and describes plans for computer-based library and information systems.…

Discusses problems in scholarly communication, particularly pricing strategies for scientific and technical journals and their impact on academic libraries' collection development. Highlights include the growth rate in scholarly titles; serials expenditures; research and development expenditures; expenditures at Louisiana State University; shared…
