An analysis of price and scientific value of chemistry journals concluded that scientific value does not play a role in the pricing of scientific journals and that consequently little relationship exists between scientific value and the prices charged libraries for journals. Describes a software package, Serials Evaluator, being developed at…

Students in grades three to four can collect, analyze, and represent data in order to determine which piece of playground equipment appears most popular. Students in grades five to six can investigate the geometry of playground structures using measurement and scale models. Lesson plans and reproducible worksheets are included. (CMS)

Describes geographic information systems and the assembly of data for analysis for the Indianapolis-Marion County Public Library (Indiana). Presents examples of possible analyses: distribution of library patrons; distances patrons travel to use libraries; branch library services and characteristics of populations served; numbers of patrons served…

A didactic example is presented of the application of new developments in structural equation modeling that allow for the modeling of multilevel data. The method, a synthesis of methods developed by B. Muthen, is applied to the problem of validating indicators of science education quality in the United States. (SLD)

Points out that data analysis and representation are political acts in the research process. Argues that research methods should be demystified and made available for public criticism. Calls for the involvement of research participants in the development of research projects and for explorations of postmodern conceptions of subjectivity, knowledge…

Describes work to develop a computer game to teach scientific reasoning. A framework for intelligent tutoring games is presented that includes developing a model of scientific knowledge, developing a model of the phenomenon, developing hypotheses, collecting data, analyzing data, and drawing conclusions. Student attitudes are also discussed. (LRW)

The SEPATH structural equation modeling (SEM) software is a new module in the latest release of STATISTICA (version 5.0) for Windows 3.1 and Windows 95. SEPATH is a program that provides a comprehensive set of functions for the SEM modeling. The interface and the Monte Carlo capability are strong features. (SLD)

BMDP/Diamond for Windows was developed as a stand-alone software package for initial data exploration and screening. The program uses advanced visualization techniques to allow one to examine the data from different perspectives, or to manipulate graphics to gain greater insight. Data can be checked quickly for a variety of characteristics. (SLD)

Presents ways in which thematization can be used to control hortatory rhetoric, including varying the complexity of thematic structure and varying the amount of discourse participant themes. The article examines how different choices of thematic progression as text organizers can produce different effects and finds correlations with the…

Examines the use of chaos theory in modelling time series data generated by computer-mediated communication (CMC). Data generated by CMC discussion groups are examined for the presence of chaotic behavior and to assess the variance which can be accounted for by the deterministic mechanism. (Author/LRW)

Discusses the use of mathematics, specifically spreadsheets, to study apportionment in the U. S. House of Representatives. Topics include the interdisciplinary nature of the study, how population changes affect the distribution, different methods for apportioning representatives that have been used throughout history, and analyzing the data. (LRW)

Describes an experiment to demonstrate a simple method for measuring fungus growth by monitoring the effect of temperature on the growth of Trichoderma viride. Among the advantages that this experimental model provides is introducing students to the importance of using the computer as a scientific tool for analyzing and presenting data. (AIM)

Pathfinder is a graphic theoretic technique used to analyze proximity data. This study evaluates its validity: (1) for representing and comparing individuals' navigation through a computer-based hypermedia environment; and (2) for generating an empirically-derived path that represents a set of individual navigational paths during computer-assisted…

Calls for principals to collect data on student performance that go beyond scores on high-stakes tests. Explains reasons for selecting student assessment data that are reliable, universal, and understandable. Describes three advantages of commercial electronic assessment programs: quick feedback, ease of use, and multiplicity. (PKP)

Describes a project that gives students hands-on experience in the careers of statistician and mathematics teacher as they plan and teach a lesson on problem-solving, then assess its effectiveness. (Author)
