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)

Presents questions, explorations, and problems centered on data and surveys related to ice cream. (YDS)

Presents an activity in which students gather and analyze data involving the compatibility of human blood types. Uses student surveys, Venn diagrams, and random numbers. Includes activity sheets. (Author/NB)

Describes a two-week unit based on calendars and births designed to be used in January at the start of each new year. (YDS)

Investigates how mathematics is used in various careers. Students explore number sense and operations, logical reasoning, data analysis, and algebra. (Author/NB)

Presents an investigation to engage students in real-life, open-ended data analysis. Allows students to analyze existing data along with data that they collect. Lists steps, necessary materials, and includes activity sheets. (Author/NB)

Studied the reliability and convergent validity for 27 composite scales and 2 items covering aspects of alcohol use, smoking, marijuana use, and other drug use. Results indicate 23 of the 27 composite scales had at least acceptable reliability and the remaining 4 scales had at least marginally acceptable reliability. At least moderate construct…
